2006-09-26[PATCH] i386: Account spinlocks to the caller during profiling for !FP kernelsAndi Kleen
This ports the algorithm from x86-64 (with improvements) to i386. Previously this only worked for frame pointer enabled kernels. But spinlocks have a very simple stack frame that can be manually analyzed. Do this. Signed-off-by: Andi Kleen <ak@suse.de>

2006-09-26[PATCH] A few trivial spelling and grammar fixesAdam Henley
A few trivial spelling and grammar mistakes picked up in "arch/x86_64/aperture.c", "arch/x86_64/crash.c" and "arch/x86_64/apic.c". I think all are correct fixes but am ever aware of my fallibility :o) This is my first patch submission so all feedback is appreciated, esp. WRT CCing to Linus, Andi and trivial@kernel.org, is this correct? And which is the most appropriate kernel version to diff against? If any.

2006-09-26[PATCH] x86-64 TIF flags for debug regs and io bitmap in ctxswStephane Eranian
Hello, Following my discussion with Andi. Here is a patch that introduces two new TIF flags to simplify the context switch code in __switch_to(). The idea is to minimize the number of cache lines accessed in the common case, i.e., when neither the debug registers nor the I/O bitmap are used. This patch covers the x86-64 modifications. A patch for i386 follows. Changelog: - add TIF_DEBUG to track when debug registers are active - add TIF_IO_BITMAP to track when I/O bitmap is used - modify __switch_to() to use the new TIF flags <signed-off-by>: eranian@hpl.hp.com Signed-off-by: Andi Kleen <ak@suse.de>

2006-09-26[PATCH] x86: Add portable getcpu callAndi Kleen
For NUMA optimization and some other algorithms it is useful to have a fast to get the current CPU and node numbers in user space. x86-64 added a fast way to do this in a vsyscall. This adds a generic syscall for other architectures to make it a generic portable facility. I expect some of them will also implement it as a faster vsyscall. The cache is an optimization for the x86-64 vsyscall optimization. Since what the syscall returns is an approximation anyways and user space often wants very fast results it can be cached for some time. The norma methods to get this information in user space are relatively slow The vsyscall is in a better position to manage the cache because it has direct access to a fast time stamp (jiffies). For the generic syscall optimization it doesn't help much, but enforce a valid argument to keep programs portable I only added an i386 syscall entry for now. Other architectures can follow as needed. AK: Also added some cleanups from Andrew Morton Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26[PATCH] Add the vgetcpu vsyscallVojtech Pavlik
This patch adds a vgetcpu vsyscall, which depending on the CPU RDTSCP capability uses either the RDTSCP or CPUID to obtain a CPU and node numbers and pass them to the program. AK: Lots of changes over Vojtech's original code: Better prototype for vgetcpu() It's better to pass the cpu / node numbers as separate arguments to avoid mistakes when going from SMP to NUMA. Also add a fast time stamp based cache using a user supplied argument to speed things more up. Use fast method from Chuck Ebbert to retrieve node/cpu from GDT limit instead of CPUID Made sure RDTSCP init is always executed after node is known.

2006-09-26[PATCH] x86: i386/x86-64 Add nmi watchdog support for new Intel CPUsVenkatesh Pallipadi
AK: This redoes the changes I temporarily reverted. Intel now has support for Architectural Performance Monitoring Counters ( Refer to IA-32 Intel Architecture Software Developer's Manual http://www.intel.com/design/pentium4/manuals/253669.htm ). This feature is present starting from Intel Core Duo and Intel Core Solo processors. What this means is, the performance monitoring counters and some performance monitoring events are now defined in an architectural way (using cpuid). And there will be no need to check for family/model etc for these architectural events. Below is the patch to use this performance counters in nmi watchdog driver.

2006-09-26[PATCH] i386: Enable NMI watchdog by defaultAndi Kleen
I've had good experiences with having this on by default on x86-64. It turns nasty hangs into easier to debug oopses. Enable the local APIC wdog by default for systems newer than 2004. This comes from a strange compromise: according to arjan the reason it was off by default was some old IBM systems that corrupted registered when NMI happened in SMI. Can't remember more specific, but >= 2004 should avoid these. It's probably overly broad because most older systems should be ok (and the really old systems won't be supported by the local apic watchdog anyways) Signed-off-by: Andi Kleen <ak@suse.de>

2006-09-26[PATCH] x86: Allow users to force a panic on NMIDon Zickus
To quote Alan Cox: The default Linux behaviour on an NMI of either memory or unknown is to continue operation. For many environments such as scientific computing it is preferable that the box is taken out and the error dealt with than an uncorrected parity/ECC error get propogated. A small number of systems do generate NMI's for bizarre random reasons such as power management so the default is unchanged. In other respects the new proc/sys entry works like the existing panic controls already in that directory. This is separate to the edac support - EDAC allows supported chipsets to handle ECC errors well, this change allows unsupported cases to at least panic rather than cause problems further down the line.

By entering a non-zero value here, a user can enable the nmi watchdog to monitor the online cpus in the system.

This patch cleans up the NMI interrupt path. Instead of being gated by if the 'nmi callback' is set, the interrupt handler now calls everyone who is registered on the die_chain and additionally checks the nmi watchdog, reseting it if enabled.

Incorporates the new performance counter reservation system in oprofile. Also cleans up a lot of the initialization code.

2006-09-26[PATCH] x86: Add performance counter reservation framework for UP kernelsDon Zickus
Adds basic infrastructure to allow subsystems to reserve performance counters on the x86 chips. Only UP kernels are supported in this patch to make reviewing easier. The SMP portion makes a lot more changes. Think of this as a locking mechanism where each bit represents a different counter. In addition, each subsystem should also reserve an appropriate event selection register that will correspond to the performance counter it will be using (this is mainly neccessary for the Pentium 4 chips as they break the 1:1 relationship to performance counters). This will help prevent subsystems like oprofile from interfering with the nmi watchdog. Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>

2006-09-25[PATCH] VIDIOC_ENUMSTD bugJonathan Corbet
The v4l2 API documentation for VIDIOC_ENUMSTD says: To enumerate all standards applications shall begin at index zero, incrementing by one until the driver returns EINVAL. The actual code, however, tests the index this way: if (index<=0 || index >= vfd->tvnormsize) { ret=-EINVAL; So any application which passes in index=0 gets EINVAL right off the bat - and, in fact, this is what happens to mplayer. So I think the following patch is called for, and maybe even appropriate for a 2.6.18.x stable release.

2006-09-25[PATCH] load_module: no BUG if module_subsys uninitializedEd Swierk
Invoking load_module() before param_sysfs_init() is called crashes in mod_sysfs_setup(), since the kset in module_subsys is not initialized yet. In my case, net-pf-1 is getting modprobed as a result of hotplug trying to create a UNIX socket. Calls to hotplug begin after the topology_init initcall. Another patch for the same symptom (module_subsys-initialize-earlier.patch) moves param_sysfs_init() to the subsys initcalls, but this is still not early enough in the boot process in some cases. In particular, topology_init() causes /sbin/hotplug to run, which requests net-pf-1 (the UNIX socket protocol) which can be compiled as a module. Moving param_sysfs_init() to the postcore initcalls fixes this particular race, but there might well be other cases where a usermodehelper causes a module to load earlier still. The patch makes load_module() return an error rather than crashing the kernel if invoked before module_subsys is initialized.
