| * ARM: ftrace: enable function graph tracerRabin Vincent2010-11-192-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Add the options to enable the function graph tracer on ARM. Function graph tracer support requires frame pointers, so exclude Thumb-2 and also make sure FRAME_POINTER gets enabled when FUNCTION_GRAPH_TRACER is used, since FUNCTION_TRACER doesn't "select FRAME_POINTER" when ARM_UNWIND is used. Therefore, with GCC 4.4.0+, you get plain function tracing without frame pointers, but you'll need them if you want function graph tracing.

| * | ARM: perf: separate PMU backends into multiple filesWill Deacon2010-11-254-2352/+2390
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ARM perf_event.c file contains all PMU backends and, as new PMUs are introduced, will continue to grow. This patch follows the example of x86 and splits the PMU implementations into separate files which are then #included back into the main file. Compile-time guards are added to each PMU file to avoid compiling in code that is not relevant for the version of the architecture which we are targetting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, perf uses the PMU ID as an index into a string table to look up the name of a given PMU. This patch encodes the name of a PMU directly into the arm_pmu structure so that PMU-specific code can be factored out into separate files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In preparation for separating the PMU-specific code, this patch adds self-contained init functions to each PMU, therefore removing any PMU-specific knowledge from the PMU-agnostic init_hw_perf_events function.

| * | ARM: perf: consolidate common PMU behaviourWill Deacon2010-11-251-93/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions for mapping PMU events (perf, cache and raw) are common between all PMU types and differ only in the data on which they operate. This patch implements common definitions of these mapping functions and changes the arm_pmu struct to hold pointers to the data which they require. This is in anticipation of separating out the PMU-specific code into separate files.

They were instead only checking maxbit at the byte level. To fix this, add a compare and a conditional move instruction to the end of the common bit-within-the- byte code used by all the functions and be sure not to clobber the maxbit argument before it is used.

If \inc != 4 then we will store the data to the wrong offset from \ptr. Luckily, the only caller that passes \rept=2 to this function is __clear_user so we haven't been actively corrupting user data. This patch fixes usracc to pass \inc instead of #4 to usraccoff when it is called a second time.
