perf record: Move perf_mmap__write_tail to perf.h

2011-01-22T21:56:29+00:00

Close to perf_mmap__read_head() and the perf_mmap struct definition.
This is useful for any recorder, and we will need it in 'perf test'.

perf tools: Move __used from perf.h to linux/compiler.h

2010-03-26T07:52:59+00:00

Just like in the kernel and also to remove the need to include
perf.h in the symbol subsystem.

perf, ARM: Modify kuser rmb() call to compile for Thumb-2

2010-03-04T11:13:28+00:00

The Thumb-2 instruction set does not provide an encoding
for sub pc, r0, #95 as present in the rmb() definition used
by perf. This results in compilation failure when using a
compiler targetting an instruction set other than ARM.

This patch redefines rmb() for ARM by casting the address
of the kuser helper to a function pointer, therefore getting
the compiler to take care of making the call.

Patch taken against tip/master.

perf tools: Allow building for ARM

2009-12-11T12:50:21+00:00

Add definitions of rmb() and cpu_relax() and include the ARM
unistd.h header. The __kuser_memory_barrier helper in the helper
page is used to provide the correct memory barrier depending on
the CPU type.

[ The rmb() will work on v6 and v7, segfault on v5. Dynamic
  detection to add v5 support will be added later. ]
