perf intel-pt: Fix packet decoding of CYC packets

2018-07-03T09:23:15+00:00

commit 621a5a327c1e36ffd7bb567f44a559f64f76358f upstream.

Use a 64-bit type so that the cycle count is not limited to 32-bits.

perf intel-pt: Fix "Unexpected indirect branch" error

2018-07-03T09:23:15+00:00

commit 9fb523363f6e3984457fee95bb7019395384ffa7 upstream.

Some Atom CPUs can produce FUP packets that contain NLIP (next linear
instruction pointer) instead of CLIP (current linear instruction
pointer).  That will result in "Unexpected indirect branch" errors. Fix
by comparing IP to NLIP in that case.

perf intel-pt: Fix MTC timing after overflow

2018-07-03T09:23:15+00:00

commit dd27b87ab5fcf3ea1c060b5e3ab5d31cc78e9f4c upstream.

On some platforms, overflows will clear before MTC wraparound, and there
is no following TSC/TMA packet. In that case the previous TMA is valid.
Since there will be a valid TMA either way, stop setting 'have_tma' to
false upon overflow.

perf intel-pt: Fix decoding to accept CBR between FUP and corresponding TIP

2018-07-03T09:23:15+00:00

commit bd2e49ec48feb1855f7624198849eea4610e2286 upstream.

It is possible to have a CBR packet between a FUP packet and
corresponding TIP packet. Stop treating it as an error.

perf intel-pt: Fix sync_switch INTEL_PT_SS_NOT_TRACING

2018-07-03T09:23:15+00:00

commit dbcb82b93f3e8322891e47472c89e63058b81e99 upstream.

sync_switch is a facility to synchronize decoding more closely with the
point in the kernel when the context actually switched.

In one case, INTEL_PT_SS_NOT_TRACING state was not correctly
transitioning to INTEL_PT_SS_TRACING state due to a missing case clause.
Add it.

perf tools: Fix symbol and object code resolution for vdso32 and vdsox32

2018-07-03T09:23:15+00:00

commit aef4feace285f27c8ed35830a5d575bec7f3e90a upstream.

Fix __kmod_path__parse() so that perf tools does not treat vdso32 and
vdsox32 as kernel modules and fail to find the object.

perf/tools: header file sync up

2018-06-05T08:28:58+00:00

When building tools/perf/ it rightly complains about a number of .h
files being out of sync.  Fix this up by syncing them properly with the
relevant in-kernel versions.

tools include: Move ARRAY_SIZE() to linux/kernel.h

2018-06-05T08:28:57+00:00

commit 8607c1ee734d12f62c6a46abef13a510e25a1839 upstream.

To match the kernel, then look for places redefining it to make it use
this version, which checks that its parameter is an array at build time.
