The problem concerns a race condition in the code around the safe_halt() call in the default_idle() routine. Setting 'nohalt' on the kernel command line causes the long wakeups to disappear. void default_idle (void) { local_irq_enable(); while (!need_resched()) { --> if (can_do_pal_halt) --> safe_halt(); else A timer tick could arrive between the check for !need_resched and the actual call to safe_halt() (which does a pal call to PAL_HALT_LIGHT). By the time the timer tick completes, a thread that might now need to run could get held up for as long as a timer tick waiting for the halted cpu. I'm proposing that we disable irq's and check need_resched again before calling safe_halt(). Does anyone see any problem with this approach?

Peter Anvin" Date: Mon, 13 Aug 2007 16:27:42 -0700 Subject: [x86 setup] Don't use EDD to get the MBR signature At least one machine has been identified in the field which advertises EDD for all drives but locks up if one attempts an extended read from a non-primary drive. The MBR is always at CHS 0-0-1, so there is no reason to use an extended read, other than the possibility that the BIOS cannot handle it. Although this might break as many machines as it fixes (a small number either way), the current state is a regression but the reverse is not. Therefore revert to the previous state of not using extended read. Quite probably the Right Thing to do is to read using plain (CHS) read and extended read on failure, but that change would definitely have to go through -mm first. Signed-off-by: H.

If PAL_GET_PSTATE returns -1, such as when running on Xen, scaling_cur_freq is happy to return 4294967285 kHz (ie. (unsigned)-11). The other drivers appear to return 0 for a failure, and doing so gives me the max frequency from scaling_cur_frequency and "" from cpuinfo_cur_frequency. I believe that's the desired behavior.

When the address accessed is below the first mapping the previous mapping is returned as NULL, and this case is handled. However, when the address accessed is above the highest mapping the vma returned is NULL, this case is not handled correctly, and it fails to spot that this access might require an existing mapping to grow upwards.

Miller" Date: Thu, 16 Aug 2007 22:59:49 -0700 Subject: [MATH-EMU]: Fix underflow exception reporting. The underflow exception cases were wrong. This is one weird area of ieee1754 handling in that the underflow behavior changes based upon whether underflow is enabled in the trap enable mask of the FPU control register. As a specific case the Sparc V9 manual gives us the following description: -------------------- If UFM = 0: Underflow occurs if a nonzero result is tiny and a loss of accuracy occurs. Tininess may be detected before or after rounding. Loss of accuracy may be either a denormalization loss or an inexact result. If UFM = 1: Underflow occurs if a nonzero result is tiny. Tininess may be detected before or after rounding. -------------------- What this amounts to in the packing case is if we go subnormal, we set underflow if any of the following are true: 1) rounding sets inexact 2) we ended up rounding back up to normal (this is the case where we set the exponent to 1 and set the fraction to zero), this should set inexact too 3) underflow is set in FPU control register trap-enable mask The initially discovered example was "DBL_MIN / 16.0" which incorrectly generated an underflow. It should not, unless underflow is set in the trap-enable mask of the FPU csr. Another example, "0x0.0000000000001p-1022 / 16.0", should signal both inexact and underflow. The cpu implementations and ieee1754 literature is very clear about this. This is case #2 above. However, if underflow is set in the trap enable mask, only underflow should be set and reported as a trap. That is handled properly by the prioritization logic in arch/sparc{,64}/math-emu/math.c:record_exception(). Based upon a report and test case from Jakub Jelinek. Signed-off-by: David S.

For i386, however, smpboot.c:smp_callin() calls wait_for_init_deassert() which is buggy for mach-default and mach-es7000 cases. [ I test-built a kernel -- smp_callin() itself got inlined in its only callsite, smpboot.c:start_secondary() -- and the relevant piece of code disassembles to the following: 0xc1019704 : mov 0xc144c4c8,%eax 0xc1019709 : test %eax,%eax 0xc101970b : je 0xc1019709 init_deasserted (at 0xc144c4c8) gets fetched into %eax only once and then we loop over the test of the stale value in the register only, so these look like real bugs to me. With the fix below, this becomes: 0xc1019706 : pause 0xc1019708 : cmpl $0x0,0xc144c4c8 0xc101970f : je 0xc1019706 which looks nice and healthy. ] Thanks to Heiko Carstens for noticing this.

It works around the problem by disabling interrupts on the nic but makes a printk while holding device spinlog - which isn't smart thing to do if you have netconsole on the same nic. This patch moves the printk's out of the spinlock protected area. Without this patch the machine hangs hard. With this patch everything still works even when there is significant increase on CPU usage while using the nic.

In some cases the paravirt patchers will choose to leave the patch site unpatched (length mismatch, clobbers mismatch, etc). This causes the new patching code to copy an uninitialized temp buffer, i.e. garbage, to the callsite. Simply make sure to always initialize the buffer with the original instruction stream. A better fix is to audit all the patchers and return proper length so that apply_paravirt() can skip copies when we leave the patch site untouched.

Unfortunately, querying the CAFE i2c controller too soon after a write causes the hardware to flake. The problem had been "solved" with an msleep() call, but, between the number of registers and how msleep() behaves, that resulted in a 3-second delay on camera initialization. Instead, we hand-code a wait for the completion interrupt which avoids reading the status registers.

It passed aio+dio stress testing and some bug regression testing on ext3. This patch was introduced by Linus in the conversation that lead up to Badari's minimal fix to manually zero .map_bh.b_state in commit: 6a648fa72161d1f6468dabd96c5d3c0db04f598a It makes the code a bit smaller.

So the resulting intent of the patch isn't a performance gain but to avoid exposing ourselves to the risk of finding another field like .map_bh.b_state where we rely on zeroing but don't enforce it in the code.

There are several s390 diagnose calls, which must be executed below the 2GB memory boundary. In order to enforce this, those diagnoses must be compiled into the kernel.

Unfortunately it can happen, that there is still a user of the device structure, when the character device is open during the detach process. To fix this, reference counting for the vmur structure is introduced. In addition to that, the online, offline, probe and remove functions are serialized now using a global mutex.

The instruction length is encoded into the first two bits of the s390 instruction. Kprobe is incorrectly computing the instruction length. The instruction length is used for determining what type of "fix-up" is needed for conditional branch instruction. The problem can bee seen by placing a kprobe on a "bc" instruction that will not branch. The results is that Kprobe incorrectly computes the new instruction pointer (psw.addr) after single stepping the instruction. The problem is corrected with this patch.

Because the close function sends the 'abort' command, a parameter is added that allows the caller of garmin_write_bulk to specify, if the 'ack' should be propagated to the serial link or dimissed. This fixes the problem with gpsbabel, it has sent several packets that were acknowledged before they were sent to the GPS and GpsBabel closed the device - thus effectively cancelled all outstanding requests in the queue. - removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed them into counters. It evades USB reset of the gps on every device close.

Without both bytes, we assume the device has been disconnected. Lack of the second byte shouldn't matter much, since the spec requires it always to be equal to 0.

The first problem, which apparently has been around for a while although nobody noticed it, shows up when an aborted command is still pending when a disconnect occurs. The SCSI error-handler will continue to wait in command_abort() until the us->notify completion is signalled. Thus quiesce_and_remove_host() needs to signal it. The second problem was introduced recently along with autosuspend support. Since usb_stor_scan_thread() now calls usb_autopm_put_interface() before exiting, we can't simply leave the scanning thread running after a disconnect; we must wait until the thread exits. This is solved by adding a new struct completion to the private data structure. Fortuitously, it allows the removal of the rather clunky mechanism used in the past to insure that all threads have finished before the module is unloaded.

안정 커널 트리 +------------------------ + +4 자리 숫자로 이루어진 버젼의 커널들은 -stable 커널들이다. 그것들은 2.6.x +커널에서 발견된 큰 퇴보들이나 보안 문제들 중 비교적 작고 중요한 수정들을 +포함한다. + +이것은 가장 최근의 안정적인 커널을 원하는 사용자에게 추천되는 브랜치이며, +개발/실험적 버젼을 테스트하는 것을 돕는데는 별로 관심이 없다. + +어떤 2.6.x.y 커널도 사용가능하지 않다면 그때는 가장 높은 숫자의 2.6.x +커널이 현재의 안정 커널이다. + +2.6.x.y는 "stable" 팀에 의해 관리되며 거의 매번 격주로 +배포된다. + +커널 트리 문서들 내에 Documentation/stable_kernel_rules.txt 파일은 어떤 +종류의 변경들이 -stable 트리로 들어왔는지와 배포 프로세스가 어떻게 +진행되는지를 설명한다. + + +2.6.x -git 패치들 +------------------ +git 저장소(그러므로 -git이라는 이름이 붙음)에는 날마다 관리되는 Linus의 +커널 트리의 snapshot 들이 있다. 이 패치들은 일반적으로 날마다 배포되며 +Linus의 트리의 현재 상태를 나타낸다. 이 패치들은 정상적인지 조금도 +살펴보지 않고 자동적으로 생성된 것이므로 -rc 커널들 보다도 더 실험적이다. + +2.6.x -mm 커널 패치들 +--------------------- +Andrew Morton에 의해 배포된 실험적인 커널 패치들이다. Andrew는 모든 다른 +서브시스템 커널 트리와 패치들을 가져와서 리눅스 커널 메일링 리스트로 +온 많은 패치들과 한데 묶는다. 이 트리는 새로운 기능들과 패치들을 위한 +장소를 제공하는 역할을 한다. 하나의 패치가 -mm에 한동안 있으면서 그 가치가 +증명되게 되면 Andrew나 서브시스템 메인트너는 그것을 메인라인에 포함시키기 +위하여 Linus에게 보낸다. + +커널 트리에 포함하고 싶은 모든 새로운 패치들은 Linus에게 보내지기 전에 +-mm 트리에서 테스트를 하는 것을 적극 추천한다. + +이 커널들은 안정되게 사용할 시스템에서에 실행하는 것은 적합하지 않으며 +다른 브랜치들의 어떤 것들보다 위험하다. + +여러분이 커널 개발 프로세스를 돕길 원한다면 이 커널 배포들을 사용하고 +테스트한 후 어떤 문제를 발견하거나 또는 모든 것이 잘 동작한다면 리눅스 +커널 메일링 리스트로 피드백을 해달라. + +이 커널들은 일반적으로 모든 다른 실험적인 패치들과 배포될 당시의 +사용가능한 메인라인 -git 커널들의 몇몇 변경을 포함한다. + +-mm 커널들은 정해진 일정대로 배포되지 않는다. 하지만 대개 몇몇 -mm 커널들은 +각 -rc 커널(1부터 3이 흔함) 사이에서 배포된다. + +서브시스템 커널 트리들과 패치들 +------------------------------- +많은 다른 커널 서브시스템 개발자들은 커널의 다른 부분들에서 무슨 일이 +일어나고 있는지를 볼수 있도록 그들의 개발 트리를 공개한다. 이 트리들은 +위에서 설명하였던 것 처럼 -mm 커널 배포들로 합쳐진다. + +다음은 활용가능한 커널 트리들을 나열한다. + git trees: + - Kbuild development tree, Sam Ravnborg < sam@ravnborg.org> + git.kernel.org:/pub/scm/linux/kernel/git/sam/kbuild.git + + - ACPI development tree, Len Brown + git.kernel.org:/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git + + - Block development tree, Jens Axboe + git.kernel.org:/pub/scm/linux/kernel/git/axboe/linux-2.6-block.git + + - DRM development tree, Dave Airlie + git.kernel.org:/pub/scm/linux/kernel/git/airlied/drm-2.6.git + + - ia64 development tree, Tony Luck < tony.luck@intel.com> + git.kernel.org:/pub/scm/linux/kernel/git/aegl/linux-2.6.git + + - infiniband, Roland Dreier + git.kernel.org:/pub/scm/linux/kernel/git/roland/infiniband.git + + - libata, Jeff Garzik + git.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev.git + + - network drivers, Jeff Garzik + git.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6.git + + - pcmcia, Dominik Brodowski < linux@dominikbrodowski.net> + git.kernel.org:/pub/scm/linux/kernel/git/brodo/pcmcia-2.6.git + + - SCSI, James Bottomley < James.Bottomley@SteelEye.com> + git.kernel.org:/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6.git + + quilt trees: + - USB, PCI, Driver Core, and I2C, Greg Kroah-Hartman < gregkh@suse.de> + kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/ + - x86-64, partly i386, Andi Kleen < ak@suse.de> + ftp.firstfloor.org:/pub/ak/x86_64/quilt/ + + 다른 커널 트리들은 http://kernel.org/git와 MAINTAINERS 파일에서 참조할 수 + 있다. + +버그 보고 +--------- +bugzilla.kernel.org는 리눅스 커널 개발자들이 커널의 버그를 추적하는 곳이다. +사용자들은 발견한 모든 버그들을 보고하기 위하여 이 툴을 사용할 것을 권장한다. +kernel bugzilla를 사용하는 자세한 방법은 다음을 참조하라. + http://test.kernel.org/bugzilla/faq.html + +메인 커널 소스 디렉토리에 있는 REPORTING-BUGS 파일은 커널 버그일 것 같은 +것을 보고하는는 법에 관한 좋은 템플릿이고 문제를 추적하기 위해서 커널 +개발자들이 필요로 하는 정보가 무엇들인지를 상세히 설명하고 있다. + + +버그 리포트들의 관리 +-------------------- + +여러분의 해킹 기술을 연습하는 가장 좋은 방법 중의 하는 다른 사람들이 +보고한 버그들을 수정하는 것이다. 여러분은 커널을 더욱 안정화시키는데 +도움을 줄 뿐만이 아니라 실제있는 문제들을 수정하는 법을 배우게 되고 +그와 함께 여러분들의 기술은 향상될 것이며 다른 개발자들이 여러분의 +존재에 대해 알게 될 것이다. 버그를 수정하는 것은 개발자들 사이에서 +점수를 얻을 수 있는 가장 좋은 방법중의 하나이다. 왜냐하면 많은 사람들은 +다른 사람들의 버그들을 수정하기 위하여 시간을 낭비하지 않기 때문이다. + +이미 보고된 버그 리포트들을 가지고 작업하기 위해서 http://bugzilla.kernelorg를 +참조하라. 여러분이 앞으로 생겨날 버그 리포트들의 조언자가 되길 원한다면 +bugme-new 메일링 리스트나(새로운 버그 리포트들만이 이곳에서 메일로 전해진다) +bugme-janitor 메일링 리스트(bugzilla에 모든 변화들이 여기서 메일로 전해진다) +에 등록하면 된다. + + http://lists.osdl.org/mailman/listinfo/bugme-new + http://lists.osdl.org/mailman/listinfo/bugme-janitors + + + +메일링 리스트들 +--------------- + +위의 몇몇 문서들이 설명하였지만 핵심 커널 개발자들의 대다수는 +리눅스 커널 메일링 리스트에 참여하고 있다. 리스트에 등록하고 해지하는 +방법에 관한 자세한 사항은 다음에서 참조할 수 있다. + http://vger.kernel.org/vger-lists.html#linux-kernel +웹상의 많은 다른 곳에도 메일링 리스트의 아카이브들이 있다. +이러한 아카이브들을 찾으려면 검색 엔진을 사용하라. 예를 들어: + http://dir.gmane.org/gmane.linux.kernel +여러분이 새로운 문제에 관해 리스트에 올리기 전에 말하고 싶은 주제에 대한 +것을 아카이브에서 먼저 찾기를 강력히 권장한다. 이미 상세하게 토론된 많은 +것들이 메일링 리스트의 아카이브에 기록되어 있다. + +각각의 커널 서브시스템들의 대부분은 자신들의 개발에 관한 노력들로 이루어진 +분리된 메일링 리스트를 따로 가지고 있다. 다른 그룹들이 무슨 리스트를 가지고 +있는지는 MAINTAINERS 파일을 참조하라. + +많은 리스트들은 kernel.org에서 호스트되고 있다. 그 정보들은 다음에서 참조될 수 있다. + http://vger.kernel.org/vger-lists.html + +리스트들을 사용할 때는 올바른 예절을 따를 것을 유념해라. +대단하진 않지만 다음 URL은 리스트(혹은 모든 리스트)와 대화하는 몇몇 간단한 +가이드라인을 가지고 있다. + http://www.albion.com/netiquette/ + +여러 사람들이 여러분의 메일에 응답한다면 CC: 즉 수신 리스트는 꽤 커지게 +될 것이다. 아무 이유없이 CC에서 어떤 사람도 제거하거나 리스트 주소로만 +회신하지 마라. 메일을 보낸 사람으로서 하나를 받고 리스트로부터 또 +하나를 받아 두번 받는 것에 익숙하여 있으니 mail-header를 조작하려고 하지 +말아라. 사람들은 그런 것을 좋아하지 않을 것이다. + +여러분의 회신의 문맥을 원래대로 유지해야 한다. 여러분들의 회신의 윗부분에 +"John 커널해커는 작성했다...."를 유지하며 여러분들의 의견을 그 메일의 윗부분에 +작성하지 말고 각 인용한 단락들 사이에 넣어라. + +여러분들이 패치들을 메일에 넣는다면 그것들은 Documentation/SubmittingPatches에 +나와있는데로 명백히(plain) 읽을 수 있는 텍스트여야 한다. 커널 개발자들은 +첨부파일이나 압축된 패치들을 원하지 않는다. 그들은 여러분들의 패치의 +각 라인 단위로 코멘트를 하길 원하며 압축하거나 첨부하지 않고 보내는 것이 +그렇게 할 수 있는 유일한 방법이다. 여러분들이 사용하는 메일 프로그램이 +스페이스나 탭 문자들을 조작하지 않는지 확인하라. 가장 좋은 첫 테스트는 +메일을 자신에게 보내보고 스스로 그 패치를 적용해보라. 그것이 동작하지 +않는다면 여러분의 메일 프로그램을 고치던가 제대로 동작하는 프로그램으로 +바꾸어라. + +무엇보다도 메일링 리스트의 다른 구독자들에게 보여주려 한다는 것을 기억하라. + + +커뮤니티와 일하는 법 +-------------------- + +커널 커뮤니티의 목적은 가능한한 가장 좋은 커널을 제공하는 것이다. 여러분이 +받아들여질 패치를 제출하게 되면 그 패치의 기술적인 이점으로 검토될 것이다. +그럼 여러분들은 무엇을 기대하고 있어야 하는가?

Andrea라는 이름을 가진 남자와 +Pat이라는 이름을 가진 여자가 있을 수도 있는 것이다. 리눅스 커널에서 +작업하며 생각을 표현해왔던 대부분의 여성들은 긍정적인 경험을 가지고 +있다. + +언어 장벽은 영어에 익숙하지 않은 몇몇 사람들에게 문제가 될 수도 있다. + 언어의 훌륭한 구사는 메일링 리스트에서 올바르게 자신의 생각을 +표현하기 위하여 필요하다. 그래서 여러분은 이메일을 보내기 전에 +영어를 올바르게 사용하고 있는지를 체크하는 것이 바람직하다. + + +여러분의 변경을 나누어라 +------------------------ + +리눅스 커널 커뮤니티는 한꺼번에 굉장히 큰 코드의 묶음을 쉽게 +받아들이지 않는다. 변경은 적절하게 소개되고, 검토되고, 각각의 +부분으로 작게 나누어져야 한다. 이것은 회사에서 하는 것과는 정확히 +반대되는 것이다. 여러분들의 제안은 개발 초기에 일찍이 소개되야 한다. +그래서 여러분들은 자신이 하고 있는 것에 관하여 피드백을 받을 수 있게 +된다. 커뮤니티가 여러분들이 커뮤니티와 함께 일하고 있다는 것을 +느끼도록 만들고 커뮤니티가 여러분의 기능을 위한 쓰레기 장으로서 +사용되지 않고 있다는 것을 느끼게 하자. 그러나 메일링 리스트에 한번에 +50개의 이메일을 보내지는 말아라. 여러분들의 일련의 패치들은 항상 +더 작아야 한다. + +패치를 나누는 이유는 다음과 같다. + +1) 작은 패치들은 여러분의 패치들이 적용될 수 있는 확률을 높여준다. + 왜냐하면 다른 사람들은 정확성을 검증하기 위하여 많은 시간과 노력을 + 들이기를 원하지 않는다. 5줄의 패치는 메인트너가 거의 몇 초간 힐끗 + 보면 적용될 수 있다. 그러나 500 줄의 패치는 정확성을 검토하기 위하여 + 몇시간이 걸릴 수도 있다(걸리는 시간은 패치의 크기 혹은 다른 것에 + 비례하여 기하급수적으로 늘어난다). + + 패치를 작게 만드는 것은 무엇인가 잘못되었을 때 디버그하는 것을 + 쉽게 만든다. 즉, 그렇게 만드는 것은 매우 큰 패치를 적용한 후에 + 조사하는 것 보다 작은 패치를 적용한 후에 (그리고 몇몇의 것이 + 깨졌을 때) 하나씩 패치들을 제거해가며 디버그 하기 쉽도록 만들어 준다. + +2) 작은 패치들을 보내는 것뿐만 아니라 패치들을 제출하기전에 재작성하고 + 간단하게(혹은 간단한게 재배치하여) 하는 것도 중요하다. + +여기에 커널 개발자 Al Viro의 이야기가 있다. + "학생의 수학 숙제를 채점하는 선생님을 생각해보라. 선생님은 학생들이 + 답을 얻을때까지 겪은 시행착오를 보길 원하지 않는다. 선생님들은 + 간결하고 가장 뛰어난 답을 보길 원한다. 훌륭한 학생은 이것을 알고 + 마지막으로 답을 얻기 전 중간 과정들을 제출하진 않는다. + + 커널 개발도 마찬가지이다. 메인트너들과 검토하는 사람들은 문제를 + 풀어나가는 과정속에 숨겨진 과정을 보길 원하진 않는다. 그들은 + 간결하고 멋진 답을 보길 원한다." + +커뮤니티와 함께 일하며 뛰어난 답을 찾고 여러분들의 완성되지 않은 일들 +사이에 균형을 유지해야 하는 어려움이 있을 수 있다. 그러므로 프로세스의 +초반에 여러분의 일을 향상시키기위한 피드백을 얻는 것 뿐만 아니라 +여러분들의 변경들을 작은 묶음으로 유지해서 심지어는 여러분의 작업의 +모든 부분이 지금은 포함될 준비가 되어있지 않지만 작은 부분은 이미 +받아들여질 수 있도록 유지하는 것이 바람직하다. + +또한 완성되지 않았고 "나중에 수정될 것이다." 와 같은 것들은 포함하는 +패치들은 받아들여지지 않을 것이라는 점을 유념하라. + +변경을 정당화해라 +----------------- + +여러분들의 나누어진 패치들을 리눅스 커뮤니티가 왜 반영해야 하는지를 +알도록 하는 것은 매우 중요하다. 새로운 기능들이 필요하고 유용하다는 +것은 반드시 그에 맞는 이유가 있어야 한다. + + +변경을 문서화해라 +----------------- + +여러분이 패치를 보내려 할때는 여러분이 무엇을 말하려고 하는지를 충분히 +생각하여 이메일을 작성해야 한다. 이 정보는 패치를 위한 ChangeLog가 될 +것이다. 그리고 항상 그 내용을 보길 원하는 모든 사람들을 위해 보존될 +것이다. 패치는 완벽하게 다음과 같은 내용들을 포함하여 설명해야 한다. + - 변경이 왜 필요한지 + - 패치에 관한 전체 설계 어프로치 + - 구현 상세들 + - 테스트 결과들 + +이것이 무엇인지 더 자세한 것을 알고 싶다면 다음 문서의 ChageLog 항을 봐라. + "The Perfect Patch" + http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt + + + + +이 모든 것을 하는 것은 매우 어려운 일이다. 완벽히 소화하는 데는 적어도 몇년이 +걸릴 수도 있다. 많은 인내와 결의가 필요한 계속되는 개선의 과정이다. 그러나 +가능한한 포기하지 말라. 많은 사람들은 이전부터 해왔던 것이고 그 사람들도 +정확하게 여러분들이 지금 서 있는 그 곳부터 시작했었다. + + + + +---------- +"개발 프로세스"(http://linux.tar.gz/articles/2.6-development_process) 섹션을 +작성하는데 있어 참고할 문서를 사용하도록 허락해준 Paolo Ciarrocchi에게 +감사한다. 여러분들이 말해야 할 것과 말해서는 안되는 것의 목록 중 일부를 제공해준 +Randy Dunlap과 Gerrit Huizenga에게 감사한다. 또한 검토와 의견 그리고 +공헌을 아끼지 않은 Pat Mochel, Hanna Linder, Randy Dunlap, Kay Sievers, +Vojtech Pavlik, Jan Kara, Josh Boyer, Kees Cook, Andrew Morton, Andi Kleen, +Vadim Lobanov, Jesper Juhl, Adrian Bunk, Keri Harris, Frans Pop, +David A.

Ok, lets kill the message. As Alois Nešpor also saw, that's fixed up by Yenta, so PCI does not have to warn about it. PCI could still warn about it if is_cardbus is 0 in that instance of pci_scan_bridge(), but so far I have not seen a report where this would have been the case so I think we can spare the kernel of that check (removes ~300 lines of asm) unless debugging is done. History: The whole check was added in the days before we had the fixup for this in Yenta and pci=assign-busses was the only way to get CardBus cards detected on many (not all) of the machines which give this warning. In theory, there could be cases when this warning would be triggered and it's not cardbus, then the warning should still apply, but I think this should only be the case when working on a completely broken PCI setup, but one may have already enabled the debug code in drivers/pci and the patched check would then trigger. I do not sign this off yet because it's completely untested so far, but everyone is free to test it (with the #ifdef DEBUG replaced by #if 1 and pr_debug( changed to printk(. We may also dump the whole check (remove everything within the #ifdef from the source) if that's perferred. On Alois Nešpor's machine this would then (only when debugging) this message: "PCI: Bus #0b (-#0e) is partially hidden behind transparent bridge #0a (-#0b)" "partially" should be in the message on his machine because #0b of #0b-#0e is reachable behind #0a-#0b, but not #0c-#0e. But that differentiation is now moot anyway because the fixup in Yenta takes care of it as far as I could see so far, which means that unless somebody is debugging a totally broken PCI setup, this message is not needed anymore, not even for debugging PCI. Ok, here the patch with the following changes: * Refined to say that the bus is only partially hidden when the parent bus numbers are not totally way off (outside of) the child bus range * remove the reference to pci=assign-busses and the plea to report it We could add a pure source code-only comment to keep a reference to pci=assign-busses the in case when this is triggered by someone who is debugging the cause of this message and looking the way to solve it.

Linux has +supported platforms with Non-Uniform Memory Access architectures since 2.4.?. +The current memory policy support was added to Linux 2.6 around May 2004. This +document attempts to describe the concepts and APIs of the 2.6 memory policy +support. + +Memory policies should not be confused with cpusets (Documentation/cpusets.txt) +which is an administrative mechanism for restricting the nodes from which +memory may be allocated by a set of processes. Memory policies are a +programming interface that a NUMA-aware application can take advantage of. When +both cpusets and policies are applied to a task, the restrictions of the cpuset +takes priority. See "MEMORY POLICIES AND CPUSETS" below for more details. + +MEMORY POLICY CONCEPTS + +Scope of Memory Policies + +The Linux kernel supports _scopes_ of memory policy, described here from +most general to most specific: + + System Default Policy: this policy is "hard coded" into the kernel. It + is the policy that governs all page allocations that aren't controlled + by one of the more specific policy scopes discussed below. When the + system is "up and running", the system default policy will use "local + allocation" described below. However, during boot up, the system + default policy will be set to interleave allocations across all nodes + with "sufficient" memory, so as not to overload the initial boot node + with boot-time allocations. + + Task/Process Policy: this is an optional, per-task policy. When defined + for a specific task, this policy controls all page allocations made by or + on behalf of the task that aren't controlled by a more specific scope. + If a task does not define a task policy, then all page allocations that + would have been controlled by the task policy "fall back" to the System + Default Policy. + + The task policy applies to the entire address space of a task. Thus, + it is inheritable, and indeed is inherited, across both fork() + [clone() w/o the CLONE_VM flag] and exec*(). This allows a parent task + to establish the task policy for a child task exec()'d from an + executable image that has no awareness of memory policy. See the + MEMORY POLICY APIS section, below, for an overview of the system call + that a task may use to set/change it's task/process policy. + + In a multi-threaded task, task policies apply only to the thread + [Linux kernel task] that installs the policy and any threads + subsequently created by that thread. Any sibling threads existing + at the time a new task policy is installed retain their current + policy. + + A task policy applies only to pages allocated after the policy is + installed. Any pages already faulted in by the task when the task + changes its task policy remain where they were allocated based on + the policy at the time they were allocated. + + VMA Policy: A "VMA" or "Virtual Memory Area" refers to a range of a task's + virtual adddress space. A task may define a specific policy for a range + of its virtual address space. See the MEMORY POLICIES APIS section, + below, for an overview of the mbind() system call used to set a VMA + policy. + + A VMA policy will govern the allocation of pages that back this region of + the address space. Any regions of the task's address space that don't + have an explicit VMA policy will fall back to the task policy, which may + itself fall back to the System Default Policy. + + VMA policies have a few complicating details: + + VMA policy applies ONLY to anonymous pages. These include pages + allocated for anonymous segments, such as the task stack and heap, and + any regions of the address space mmap()ed with the MAP_ANONYMOUS flag. + If a VMA policy is applied to a file mapping, it will be ignored if + the mapping used the MAP_SHARED flag. If the file mapping used the + MAP_PRIVATE flag, the VMA policy will only be applied when an + anonymous page is allocated on an attempt to write to the mapping-- + i.e., at Copy-On-Write. + + VMA policies are shared between all tasks that share a virtual address + space--a.k.a. threads--independent of when the policy is installed; and + they are inherited across fork(). However, because VMA policies refer + to a specific region of a task's address space, and because the address + space is discarded and recreated on exec*(), VMA policies are NOT + inheritable across exec(). Thus, only NUMA-aware applications may + use VMA policies. + + A task may install a new VMA policy on a sub-range of a previously + mmap()ed region. When this happens, Linux splits the existing virtual + memory area into 2 or 3 VMAs, each with it's own policy. + + By default, VMA policy applies only to pages allocated after the policy + is installed. Any pages already faulted into the VMA range remain + where they were allocated based on the policy at the time they were + allocated. However, since 2.6.16, Linux supports page migration via + the mbind() system call, so that page contents can be moved to match + a newly installed policy. + + Shared Policy: Conceptually, shared policies apply to "memory objects" + mapped shared into one or more tasks' distinct address spaces. An + application installs a shared policies the same way as VMA policies--using + the mbind() system call specifying a range of virtual addresses that map + the shared object. However, unlike VMA policies, which can be considered + to be an attribute of a range of a task's address space, shared policies + apply directly to the shared object. Thus, all tasks that attach to the + object share the policy, and all pages allocated for the shared object, + by any task, will obey the shared policy. + + As of 2.6.22, only shared memory segments, created by shmget() or + mmap(MAP_ANONYMOUS|MAP_SHARED), support shared policy. When shared + policy support was added to Linux, the associated data structures were + added to hugetlbfs shmem segments. At the time, hugetlbfs did not + support allocation at fault time--a.k.a lazy allocation--so hugetlbfs + shmem segments were never "hooked up" to the shared policy support. + Although hugetlbfs segments now support lazy allocation, their support + for shared policy has not been completed. + + As mentioned above [re: VMA policies], allocations of page cache + pages for regular files mmap()ed with MAP_SHARED ignore any VMA + policy installed on the virtual address range backed by the shared + file mapping. Rather, shared page cache pages, including pages backing + private mappings that have not yet been written by the task, follow + task policy, if any, else System Default Policy. + + The shared policy infrastructure supports different policies on subset + ranges of the shared object. However, Linux still splits the VMA of + the task that installs the policy for each range of distinct policy. + Thus, different tasks that attach to a shared memory segment can have + different VMA configurations mapping that one shared object. This + can be seen by examining the /proc//numa_maps of tasks sharing + a shared memory region, when one task has installed shared policy on + one or more ranges of the region. + +Components of Memory Policies + + A Linux memory policy is a tuple consisting of a "mode" and an optional set + of nodes. The mode determine the behavior of the policy, while the + optional set of nodes can be viewed as the arguments to the behavior. + + Internally, memory policies are implemented by a reference counted + structure, struct mempolicy. Details of this structure will be discussed + in context, below, as required to explain the behavior. + + Note: in some functions AND in the struct mempolicy itself, the mode + is called "policy". However, to avoid confusion with the policy tuple, + this document will continue to use the term "mode". + + Linux memory policy supports the following 4 behavioral modes: + + Default Mode--MPOL_DEFAULT: The behavior specified by this mode is + context or scope dependent. + + As mentioned in the Policy Scope section above, during normal + system operation, the System Default Policy is hard coded to + contain the Default mode. + + In this context, default mode means "local" allocation--that is + attempt to allocate the page from the node associated with the cpu + where the fault occurs. If the "local" node has no memory, or the + node's memory can be exhausted [no free pages available], local + allocation will "fallback to"--attempt to allocate pages from-- + "nearby" nodes, in order of increasing "distance". + + Implementation detail -- subject to change: "Fallback" uses + a per node list of sibling nodes--called zonelists--built at + boot time, or when nodes or memory are added or removed from + the system [memory hotplug]. These per node zonelist are + constructed with nodes in order of increasing distance based + on information provided by the platform firmware. + + When a task/process policy or a shared policy contains the Default + mode, this also means "local allocation", as described above. + + In the context of a VMA, Default mode means "fall back to task + policy"--which may or may not specify Default mode. Thus, Default + mode can not be counted on to mean local allocation when used + on a non-shared region of the address space. However, see + MPOL_PREFERRED below. + + The Default mode does not use the optional set of nodes. + + MPOL_BIND: This mode specifies that memory must come from the + set of nodes specified by the policy. + + The memory policy APIs do not specify an order in which the nodes + will be searched. However, unlike "local allocation", the Bind + policy does not consider the distance between the nodes. Rather, + allocations will fallback to the nodes specified by the policy in + order of numeric node id. Like everything in Linux, this is subject + to change. + + MPOL_PREFERRED: This mode specifies that the allocation should be + attempted from the single node specified in the policy. If that + allocation fails, the kernel will search other nodes, exactly as + it would for a local allocation that started at the preferred node + in increasing distance from the preferred node. "Local" allocation + policy can be viewed as a Preferred policy that starts at the node + containing the cpu where the allocation takes place. + + Internally, the Preferred policy uses a single node--the + preferred_node member of struct mempolicy. A "distinguished + value of this preferred_node, currently '-1', is interpreted + as "the node containing the cpu where the allocation takes + place"--local allocation. This is the way to specify + local allocation for a specific range of addresses--i.e. for + VMA policies. + + MPOL_INTERLEAVED: This mode specifies that page allocations be + interleaved, on a page granularity, across the nodes specified in + the policy. This mode also behaves slightly differently, based on + the context where it is used: + + For allocation of anonymous pages and shared memory pages, + Interleave mode indexes the set of nodes specified by the policy + using the page offset of the faulting address into the segment + [VMA] containing the address modulo the number of nodes specified + by the policy. It then attempts to allocate a page, starting at + the selected node, as if the node had been specified by a Preferred + policy or had been selected by a local allocation. That is, + allocation will follow the per node zonelist. + + For allocation of page cache pages, Interleave mode indexes the set + of nodes specified by the policy using a node counter maintained + per task. This counter wraps around to the lowest specified node + after it reaches the highest specified node. This will tend to + spread the pages out over the nodes specified by the policy based + on the order in which they are allocated, rather than based on any + page offset into an address range or file. During system boot up, + the temporary interleaved system default policy works in this + mode. + +MEMORY POLICY APIs + +Linux supports 3 system calls for controlling memory policy. These APIS +always affect only the calling task, the calling task's address space, or +some shared object mapped into the calling task's address space. + + Note: the headers that define these APIs and the parameter data types + for user space applications reside in a package that is not part of + the Linux kernel. The kernel system call interfaces, with the 'sys_' + prefix, are defined in ; the mode and flag + definitions are defined in . + +Set [Task] Memory Policy: + + long set_mempolicy(int mode, const unsigned long *nmask, + unsigned long maxnode); + + Set's the calling task's "task/process memory policy" to mode + specified by the 'mode' argument and the set of nodes defined + by 'nmask'. 'nmask' points to a bit mask of node ids containing + at least 'maxnode' ids. + + See the set_mempolicy(2) man page for more details + + +Get [Task] Memory Policy or Related Information + + long get_mempolicy(int *mode, + const unsigned long *nmask, unsigned long maxnode, + void *addr, int flags); + + Queries the "task/process memory policy" of the calling task, or + the policy or location of a specified virtual address, depending + on the 'flags' argument. + + See the get_mempolicy(2) man page for more details + + +Install VMA/Shared Policy for a Range of Task's Address Space + + long mbind(void *start, unsigned long len, int mode, + const unsigned long *nmask, unsigned long maxnode, + unsigned flags); + + mbind() installs the policy specified by (mode, nmask, maxnodes) as + a VMA policy for the range of the calling task's address space + specified by the 'start' and 'len' arguments. Additional actions + may be requested via the 'flags' argument. + + See the mbind(2) man page for more details. + +MEMORY POLICY COMMAND LINE INTERFACE + +Although not strictly part of the Linux implementation of memory policy, +a command line tool, numactl(8), exists that allows one to: + ++ set the task policy for a specified program via set_mempolicy(2), fork(2) and + exec(2) + ++ set the shared policy for a shared memory segment via mbind(2) + +The numactl(8) tool is packages with the run-time version of the library +containing the memory policy system call wrappers. Some distributions +package the headers and compile-time libraries in a separate development +package. + + +MEMORY POLICIES AND CPUSETS + +Memory policies work within cpusets as described above. For memory policies +that require a node or set of nodes, the nodes are restricted to the set of +nodes whose memories are allowed by the cpuset constraints. If the +intersection of the set of nodes specified for the policy and the set of nodes +allowed by the cpuset is the empty set, the policy is considered invalid and +cannot be installed. + +The interaction of memory policies and cpusets can be problematic for a +couple of reasons: + +1) the memory policy APIs take physical node id's as arguments. However, the + memory policy APIs do not provide a way to determine what nodes are valid + in the context where the application is running.

Unfortunately, its idea of "relevant" doesn't include c_[io]speed. So if the baud rate bits are BOTHER and you just change the speed, the change gets optimised away.

As this takes finite time to drain reclaim will consider more areas than ultimatly needed to satisfy the request. This leads to more reclaim than strictly required and reduced success rates. I was able to confirm Mel's test results on systems locally. These show that even under light load the success rates drop off far more than expected. Testing with a modified version of his patch (which follows) I was able to allocate almost all of ZONE_MOVABLE with a near idle system. I ran 5 test passes sequentially following system boot (the system has 29 hugepages in ZONE_MOVABLE): 2.6.23-rc1 11 8 6 7 7 sync_lumpy 28 28 29 29 26 These show that although hugely better than the near 0% success normally expected we can only allocate about a 1/4 of the zone. Using synchronous reclaim for these allocations we get close to 100% as expected. I have also run our standard high order tests and these show no regressions in allocation success rates at rest, and some significant improvements under load. This patch: We are transitioning pages from active to inactive in clear_active_flags, those need counting as PGDEACTIVATE vm events.

In the situation were all pages in that region are inactive and not referenced by any process over time, it works well. In the situation where there is even light load on the system, the pages may not free quickly. Out of a area of 1024 pages, maybe only 950 of them are freed when the allocation attempt occurs because lumpy reclaim returned early. This patch alters the behaviour of direct reclaim for large contiguous blocks. The first attempt to call shrink_page_list() is asynchronous but if it fails, the pages are submitted a second time and the calling process waits for the IO to complete. This may stall allocators waiting for contiguous memory but that should be expected behaviour for high-order users. It is preferable behaviour to potentially queueing unnecessary areas for IO. Note that kswapd will not stall in this fashion.

By putting it in ubd_add, it covered the cases where the COWing was specified on the command line. However, when the command line only has the COW file specified, the fact that it's a COW file isn't known until it's opened, so the limit is missed in these cases. This patch moves the sector limit from ubd_add to ubd_open_dev.

The inconsistency is that the directory inode mutex is held for both lookup and revalidate calls when called via lookup_hash whereas it is held only for lookup during a path walk. Consequently, if the mutex is held during a call to revalidate autofs4 can't release the mutex to callback the daemon as it can't know whether it owns the mutex. This situation happens when a process tries to create a directory within an automount and a second process also tries to create the same directory between the lookup and the mkdir. Since the first process has dropped the mutex for the daemon callback, the second process takes it during revalidate leading to deadlock between the autofs daemon and the second process when the daemon tries to create the mount point directory. After spending quite a bit of time trying to resolve this on more than one occassion, using rather complex and ulgy approaches, it turns out that just delaying the hashing of the dentry until the create operation works fine.

When ZONE_MOVABLE is configured with kernelcore=, the the highest zone becomes ZONE_MOVABLE. The result is that policies are only applied to allocations like anonymous pages and page cache allocated from ZONE_MOVABLE when the zone is used. This patch applies policies to the two highest zones when the highest zone is ZONE_MOVABLE. As ZONE_MOVABLE consists of pages from the highest "real" zone, it's always functionally equivalent. The patch has been tested on a variety of machines both NUMA and non-NUMA covering x86, x86_64 and ppc64. No abnormal results were seen in kernbench, tbench, dbench or hackbench. It passes regression tests from the numactl package with and without kernelcore= once numactl tests are patched to wait for vmstat counters to update. akpm: this is the nasty hack to fix NUMA mempolicies in the presence of ZONE_MOVABLE and kernelcore= in 2.6.23. Christoph says "For .24 either merge the mobility or get the other solution that Mel is working on. That solution would only use a single zonelist per node and filter on the fly. That may help performance and also help to make memory policies work better."

This is followed by a number of errors and speed reduction steps on the affected ports. There are two bugs in pata_pdc2027x's PLL detection code: 1. The PLL counter's start value is read before the chip is put in "test mode". Outside of test mode the counter is halted, and on the PowerMac the counter is zero because the chip hasn't been initialised by its BIOS. The fix is to move the read of the start value to after test mode is started, but before the mdelay() in test mode. This also improves the precision of the PLL detection. 2. The code to compute the number of PLL decrements during the mdelay() in test mode fails to consider that the PLL counter only is 30 bits wide. If there is a wraparound, it will compute an incorrect and much too large value. On the PowerMac, the start count is zero, the end count is a large 30-bit value, so wraparound occurs and an out of bounds PLL clock is detected. The fix is to mask the (start - end) computation to 30 bits. While debugging this I also noticed that pdc_read_counter() reads the two halves of the 30-bit PLL counter as 16-bit values, and then combines them as if the halves only are 15 bits wide. To avoid confusion, the halves should be read as 15-bit values. This patch implements all three changes. It fixes the PLL detection failure on my PowerMac, and doesn't cause any regressions on an x86 with an identical card.

This allows the rq clock to work around TSC-stops-in-C2, TSC-gets-corrupted-in-C3 type of problems. ( Besides the scheduler's statistics this also benefits blktrace and printk-timestamps as well. ) Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup callbacks allow the scheduler to get out the most of the period where the CPU has a reliable TSC. This results in slightly more precise task statistics. the ACPI bits were acked by Len.

However, there was a minor difference between the code in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop devices using the LG-H06xF NIM. dvb-pll will probe for the presence of an i2c pll chip by performing a single byte read, the lgh06xf driver did not do this. Unfortunately, the code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads as a probe. Such probes with the current code will always fail. In order to work around this problem, and restore proper functionality of the Airstar HD5000 device, this hack was created to make the probe appear to succeed. The single byte read in dvb_pll_attach is the only place where such a probe would ever occur, so this change is safe, and will not affect any other devices. Of course, if one knew how to actually perform the read operation, it would be better to go that route. In the meantime, however, we must apply this workaround, in order to prevent the regression that causes tuning to fail on the Airstar HD5000 ATSC device. Thanks to Jarod Wilson, who had originally reported this regression, and to Geoffrey Hausheer, whose original workaround patch led us to find the actual cause of the problem.

Unfortunately, the exception handler cannot distinguish it from other interrupt causes by the SRR1 register, which gets used for this on Power 6 and others. IBM Blade servers that want to support triggering the system reset exception using a pinhole button in the front panel therefore use an extra register to determine the reset cause.

It turns out that the part of that commit that aimed to ensure that we created an SLB entry for the kernel stack on secondary CPUs when starting the CPU didn't achieve its aim, and in fact caused a regression, because get_paca()->kstack is not initialized at the point where slb_initialize is called. This therefore just reverts that part of that commit, while keeping the change to slb_flush_and_rebolt, which is correct and necessary.

By fixing the granlarity to a constany the wakeup latency it a function of the number of running tasks on the rq. Invert this relation. sysctl_sched_granularity becomes a minimum for the dynamic granularity computed from the new sysctl_sched_latency. Then use this latency to do more intelligent granularity decisions: if there are fewer tasks running then we can schedule coarser.

In testing our ESP/AH offload hardware, I discovered an issue with how AH handles mutable fields in IPv4. RFC 4302 (AH) states the following on the subject: For IPv4, the entire option is viewed as a unit; so even though the type and length fields within most options are immutable in transit, if an option is classified as mutable, the entire option is zeroed for ICV computation purposes. The current implementation does not zero the type and length fields, resulting in authentication failures when communicating with hosts that do (i.e. FreeBSD). I have tested record route and timestamp options (ping -R and ping -T) on a small network involving Windows XP, FreeBSD 6.2, and Linux hosts, with one router. In the presence of these options, the FreeBSD and Linux hosts (with the patch or with the hardware) can communicate. The Windows XP host simply fails to accept these packets with or without the patch. I have also been trying to test source routing options (using traceroute -g), but haven't had much luck getting this option to work *without* AH, let alone with.

That's because early_param parsing is a little different from __setup parsing, and needs the "=" omitted: then it seems to work as the original commit intended (no mention of IO-APIC in /proc/interrupts when maxcpus=0).
