2009-05-28x86, mce: add basic error injection infrastructureAndi Kleen
Allow user programs to write mce records into /dev/mcelog. When they do that a fake machine check is triggered to test the machine check code. This uses the MCE MSR wrappers added earlier. The implementation is straight forward. There is a struct mce record per CPU and the MCE MSR accesses get data from there if there is valid data injected there. This allows to test the machine check code relatively realistically because only the lowest layer of hardware access is intercepted. The test suite and injector are available at git://git.kernel.org/pub/scm/utils/cpu/mce/mce-test.git git://git.kernel.org/pub/scm/utils/cpu/mce/mce-inject.git Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: H.

2009-05-28x86, mce: use 64bit machine check code on 32bitAndi Kleen
The 64bit machine check code is in many ways much better than the 32bit machine check code: it is more specification compliant, is cleaner, only has a single code base versus one per CPU, has better infrastructure for recovery, has a cleaner way to communicate with user space etc. etc. Use the 64bit code for 32bit too. This is the second attempt to do this. There was one a couple of years ago to unify this code for 32bit and 64bit. Back then this ran into some trouble with K7s and was reverted. I believe this time the K7 problems (and some others) are addressed. I went over the old handlers and was very careful to retain all quirks. But of course this needs a lot of testing on old systems. On newer 64bit capable systems I don't expect much problems because they have been already tested with the 64bit kernel. I made this a CONFIG for now that still allows to select the old machine check code. This is mostly to make testing easier, if someone runs into a problem we can ask them to try with the CONFIG switched. The new code is default y for more coverage. Once there is confidence the 64bit code works well on older hardware too the CONFIG_X86_OLD_MCE and the associated code can be easily removed. This causes a behaviour change for 32bit installations. They now have to install the mcelog package to be able to log corrected machine checks. The 64bit machine check code only handles CPUs which support the standard Intel machine check architecture described in the IA32 SDM. The 32bit code has special support for some older CPUs which have non standard machine check architectures, in particular WinChip C3 and Intel P5. I made those a separate CONFIG option and kept them for now. The WinChip variant could be probably removed without too much pain, it doesn't really do anything interesting. P5 is also disabled by default (like it was before) because many motherboards have it miswired, but according to Alan Cox a few embedded setups use that one. Forward ported/heavily changed version of old patch, original patch included review/fixes from Thomas Gleixner, Bert Wesarg. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: H.

2009-05-28x86, mce: remove oops_begin() use in 64bit machine checkAndi Kleen
First 32bit doesn't have oops_begin, so it's a barrier of using this code on 32bit. On closer examination it turns out oops_begin is not a good idea in a machine check panic anyways. All oops_begin does it so check for recursive/parallel oopses and implement the "wait on oops" heuristic. But there's actually no good reason to lock machine checks against oopses or prevent them from recursion. Also "wait on oops" does not really make sense for a machine check too. Replace it with a manual bust_spinlocks/console_verbose. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: H.

2009-05-28x86, mce: remove machine check handler idle notify on 64bitAndi Kleen
i386 has no idle notifiers, but the 64bit machine check code uses them to wake up mcelog from a fatal machine check exception. For corrected machine checks found by the poller or threshold interrupts going through an idle notifier is not needed because the wake_up can is just done directly and doesn't need the idle notifier. It is only needed for logging exceptions. To be honest I never liked the idle notifier even though I signed off on it. On closer investigation the code actually turned out to be nearly. Right now machine check exceptions on x86 are always unrecoverable (lead to panic due to PCC), which means we never execute the idle notifier path. The only exception is the somewhat weird tolerant==3 case, which ignores PCC. I'll fix this in a future patch in a much cleaner way. So remove the "mcelog wakeup through idle notifier" code from 64bit. This allows to compile the 64bit machine check handler on 32bit which doesn't have idle notifiers.

2009-05-28x86, mce: implement the PPro bank 0 quirk in the 64bit machine check codeAndi Kleen
Quoting the comment: * SDM documents that on family 6 bank 0 should not be written * because it aliases to another special BIOS controlled * register. * But it's not aliased anymore on model 0x1a+ * Don't ignore bank 0 completely because there could be a valid * event later, merely don't write CTL0. This is mostly a port on the 32bit code, except that 32bit always didn't write it and didn't have the 0x1a heuristic.
