2007-03-04[MIPS] No need to write c0_compare in plat_timer_setupAtsushi Nemoto

2007-03-04[MIPS] Convert to RTC-class ds1742 driverAtsushi Nemoto
The generic rtc-ds1742 driver can be used for RBTX4927 and JMR3927 (with __swizzle_addr trick). This patch also removes MIPS local DS1742 stuff. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2007-03-04KVM: Move kvmfs magic number to <linux/magic.h>Andrew Morton
Use the standard magic.h for kvmfs. Cc: Avi Kivity <avi@qumranet.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Fix bogus failure in kvm.ko module initializationAvi Kivity
A bogus 'return r' can cause an otherwise successful module load to fail. This both denies users the use of kvm, and it also denies them the use of their machine, as it leaves a filesystem registered with its callbacks pointing into now-freed module memory. Fix by returning a zero like a good module. Thanks to Richard Lucassen <mailinglists@lucassen.org> (?) for reporting the problem and for providing access to a machine which exhibited it. Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Remove write access permissions when dirty-page-logging is enabledUri Lublin
Enabling dirty page logging is done using KVM_SET_MEMORY_REGION ioctl. If the memory region already exists, we need to remove write accesses, so writes will be caught, and dirty pages will be logged. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04kvm: move do_remove_write_access() upUri Lublin

2007-03-04KVM: Fix dirty page log bitmap size/access calculationUri Lublin
Since dirty_bitmap is an unsigned long array, the alignment and size need to take that into account. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Add missing calls to mark_page_dirty()Uri Lublin
A few places where we modify guest memory fail to call mark_page_dirty(), causing live migration to fail. This adds the missing calls. Signed-off-by: Uri Lublin <uril@qumranet.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Bump API versionAvi Kivity
Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Per-vcpu inodesAvi Kivity
Allocate a distinct inode for every vcpu in a VM. This has the following benefits: - the filp cachelines are no longer bounced when f_count is incremented on every ioctl() - the API and internal code are distinctly clearer; for example, on the KVM_GET_REGS ioctl, there is no need to copy the vcpu number from userspace and then copy the registers back; the vcpu identity is derived from the fd used to make the call Right now the performance benefits are completely theoretical since (a) we don't support more than one vcpu per VM and (b) virtualization hardware inefficiencies completely everwhelm any cacheline bouncing effects. But both of these will change, and we need to prepare the API today. Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Move kvm_vm_ioctl_create_vcpu() aroundAvi Kivity
In preparation of some hacking. Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Rename some kvm_dev_ioctl_*() functions to kvm_vm_ioctl_*()Avi Kivity
This reflects the changed scope, from device-wide to single vm (previously every device open created a virtual machine). Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Create an inode per virtual machineAvi Kivity
This avoids having filp->f_op and the corresponding inode->i_fop different, which is a little unorthodox. The ioctl list is split into two: global kvm ioctls and per-vm ioctls. A new ioctl, KVM_CREATE_VM, is used to create VMs and return the VM fd. Signed-off-by: Avi Kivity <avi@qumranet.com>
2007-03-04KVM: Add internal filesystem for generating inodesAvi Kivity
The kvmfs inodes will represent virtual machines and vcpus, as necessary, reducing cacheline bouncing due to inodes and filps being shared. Signed-off-by: Avi Kivity <avi@qumranet.com>

2007-03-04KVM: mmu: add missing dirty page tracking casesAvi Kivity

2007-03-03ide: make legacy IDE VLB modules check for the "probe" kernel params (v2)Bartlomiej Zolnierkiewicz
Legacy IDE VLB host drivers didn't check for "probe" options when compiled as modules, which was obviously wrong as we don't want module to poke at random I/O ports by simply loading it. Fix it by adding "probe" module param to legacy IDE VLB host drivers. v2: * don't obsolete old "ide0=dtc2278/ht6560b/qd65xx/ali14xx/umc8672" IDE driver options yet (per Alan Cox's request) and enhance documentation Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Remove * "hdx=serialize" * "idex=noautotune" * "idex=autotune" kernel params, they have been obsoleted for ages. "idex=serialize", "hdx=noautotune" and "hdx=autotune" are still available so there is no funcionality loss caused by this patch. v2: * fix CONFIG_BLK_DEV_4DRIVES=y build broken by version 1 of the patch [ /me wearing brown paper bag ] Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-03-03adjust legacy IDE resource setting (v2)Jan Beulich
The change to force legacy mode IDE channels' resources to fixed non-zero values confuses (at least some versions of) X, because the values reported by the kernel and those readable from PCI config space aren't consistent anymore. Therefore, this patch arranges for the respective BARs to also get updated if possible.

2007-03-03ide: ide_get_best_pio_mode() returns incorrect IORDY setting (take 2)Sergei Shtylyov
The function ide_get_best_pio_mode() fails to return the correct IORDY setting for the explicitly specified modes -- fix this along with the heading comment, and also remove the long commented out code. Also, while at it, correct the misliading comment about the PIO cycle time in <linux/ide.h> -- it actually consists of only the active and recovery periods, with only some chips also including the address setup time into equation...

2007-03-03piix/slc90e66: more tuneproc() fixing (take 2)Sergei Shtylyov
The tuneproc() method in both these drivers failed to set the drive's own speed. Fix this by renaming the function and "wrapping around it" the new tuneproc() method. Switch back to calling tuneproc() in the PIO fallback code. While at it, also convert the rest of the PIO timing code into proper C. :-) Has been kind of tested on SLC90E66. I'm too lazy to reboot my box and test on ICH4... :-) [ bart: I quickly tested it on ICH4. ] Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-03-03ide: fix drive side 80c cable check, take 2Tejun Heo
eighty_ninty_three() had word 93 validitity check but not the 80c bit test itself (bit 13). This increases the chance of incorrect wire detection especially because host side cable detection is often unreliable and we sometimes soley depend on drive side cable detection. Fix it.
