[PATCH 1/5] perf, x86, uncore: Fix section mismatch in split uncore driver

[Andi Kleen]

From: Andi Kleen <ak@linux.intel.com>

The new split Intel uncore driver code that recently went
into tip added a section mismatch, which the build process
complains about.

uncore_pmu_register can be called from uncore_pci_probe,
which is not __init and can be called from pci driver ->probe.
I'm not fully sure if it's actually possible to call the probe
function later, but it seems safer to mark uncore_pmu_register
not __init.

This also fixes the warning.

[PATCH 2/5] perf, x86, uncore: Add Haswell-EP uncore support

[Andi Kleen]

From: "Yan, Zheng" <zheng.z.yan@intel.com>

The uncore subsystem in Haswell-EP is similar to Sandy/Ivy
Bridge-EP. There are some differences in config register
encoding and pci device IDs. The Haswell-EP uncore also
supports a few new events. Add the Haswell-EP driver to
the snbep split driver.

v2: (AK): Add missing break. Add imc events. Add cbox nc/isoc/c6.

perf/x86/intel/uncore: Add Haswell-EP uncore support

The uncore subsystem in Haswell-EP is similar to Sandy/Ivy
Bridge-EP. There are some differences in config register
encoding and pci device IDs. The Haswell-EP uncore also
supports a few new events. Add the Haswell-EP driver to
the snbep split driver.

my E5-1630 v3 crashes hard during boot in
snbep_uncore_msr_init_box()+0x3c
I don't have a setup to capture the screen so early in the boot.
So this is just heads up.
I replaced the call above with 'return -ENODEV' as a workaround.
btw, E5-16xx v3 became available just a month ago.

Is it a general general protection fault or a page fault?

If it's a page fault please post the disassembled code:

gdb vmlinux
disassemble  snbep_uncore_msr_init_box

[PATCH 3/5] perf, x86, uncore: Register the PMU only if the uncore pci device exists

[Andi Kleen]

From: "Yan, Zheng" <zheng.z.yan@intel.com>

Current code registers PMUs for all possible uncore pci devices.
This is not good because, on some machines, one or more uncore pci
devices can be missing. The missing pci device make corresponding
PMU unusable. Register the PMU only if the uncore device exists.

[PATCH 4/5] perf, x86, uncore: Add missing cbox filter flags on IvyBridge-EP uncore driver

[Andi Kleen]

From: Andi Kleen <ak@linux.intel.com>

The IvyBridge-EP uncore driver was missing three filter flags:
NC, ISOC, C6 which are useful in some cases. Support them in the same way
as the Haswell EP driver, by allowing to set them and exposing
them in the sysfs formats.

Also fix a typo in a define.

Relies on the Haswell EP driver to be applied earlier.

From: Andi Kleen <ak@linux.intel.com>

The PCU frequency band filters use 8 bit each in a register.
When setting up the value the shift value was not correctly
scaled, which resulted in all filters except for band 0 to
be zero. Fix the scaling.

This allows to correctly monitor multiple uncore frequency bands.
