commit 910081322bf9c4ed392dc8f2ecbc33fdb42a2958
Author: Eric W. Biederman <[email protected]>
Date: Wed Aug 4 12:51:11 2010 -0700

x86/apic: Map the local apic when parsing the MP table.

This fixes a regression in 2.6.35 from 2.6.34, that is
present for select models of Intel cpus when people are
using an MP table.

The commit cf7500c0ea133d66f8449d86392d83f840102632
"x86, ioapic: In mpparse use mp_register_ioapic" started
calling mp_register_ioapic from MP_ioapic_info. An extremely
simple change that was obviously correct. Unfortunately
mp_register_ioapic did just a little more than the previous
hand crafted code and so we gained this call path.

The problem call path is:
MP_ioapic_info()
mp_register_ioapic()
io_apic_unique_id()
io_apic_get_unique_id()
get_physical_broadcast()
modern_apic()
lapic_get_version()
apic_read(APIC_LVR)

Which turned out to be a problem because the local apic
was not mapped, at that point, unlike the similar point
in the ACPI parsing code.

This problem is fixed by mapping the local apic when
parsing the mptable as soon as we reasonably can.

Looking at the number of places we setup the fixmap for
the local apic, I see some serious simplification opportunities.
For the moment except for not duplicating the setting up of the
fixmap in init_apic_mappings, I have not acted on them.

The regression from 2.6.34 is tracked in bug

This one was fixed in 2.6.34.3. Mainline was OK - only the patches to stable
were affected. The bug should be closed.

I was able to reproduce this with about 50% chance in boot. But that
happened in a few rc (rc2-rc4 iirc) versions only. After that never
again.

Fix the Errata AAK100/AAP53/BD53 workaround, the officialy documented
workaround we implemented in:

11164cd: perf, x86: Add Nehelem PMU programming errata workaround

doesn't actually work fully and causes a stuck PMU state
under load and non-functioning perf profiling.

A functional workaround was found by trial & error.

Affects all Nehalem-class Intel PMUs.

I can confir this behaviour until 2.6.32-rc2. Couldn't try with -rc3
because compilation exited with error on my laptop...

Dear Rafael Wysocki,

This regression still exists in 2.6.35.4. (I haven't tested 2.6.36-rcX
series.) Kosaki Motohiro has kindly helped me with this issue and found
a fix for the regression. Today I have successfully tested his patch,
but I don't know whether the patch needs to be further refined and tested.

Regards,

M. Vefa Bicakci

Thanks for the information. Do you have a pointer to the patch?
