2011-08-12perf probe: Fix to walk all inline instancesMasami Hiramatsu
Fix line-range collector to walk all instances of inlined function, because some execution paths can be optimized out depending on the function argument of instances. E.g.) inline_func (arg) { if (arg) do_something; else do_another; } func_A() { inline_func(1) } func_B() { inline_func(0) } In this case, func_A may have only do_something code and func_B may have only do_another.

2011-08-12perf probe: Fix to search nested inlined functions in CUMasami Hiramatsu
Fix perf probe to walk through the lines of all nested inlined function call sites and declared lines when a whole CU is passed to the line walker. The die_walk_lines() can have two different type of DIEs, subprogram (or inlined-subroutine) DIE and CU DIE. If a caller passes a subprogram DIE, this means that the walker walk on lines of given subprogram. In this case, it just needs to search on direct children of DIE tree for finding call-site information of inlined function which directly called from given subprogram. On the other hand, if a caller passes a CU DIE to the walker, this means that the walker have to walk on all lines in the source files included in given CU DIE. In this case, it has to search whole DIE trees of all subprograms to find the call-site information of all nested inlined functions. Without this patch: $ perf probe --line kernel/cpu.c:151-157 </home/mhiramat/ksrc/linux-2.6/kernel/cpu.c:151> static int cpu_notify(unsigned long val, void *v) { 154 return __cpu_notify(val, v, -1, NULL); } With this: $ perf probe --line kernel/cpu.c:151-157 </home/mhiramat/ksrc/linux-2.6/kernel/cpu.c:151> 152 static int cpu_notify(unsigned long val, void *v) { 154 return __cpu_notify(val, v, -1, NULL); } As you can see, --line option with source line range shows the declared lines as probe-able.

2011-08-12drm/radeon: re-POST the asic on Apple hardware when booted via EFIMatthew Garrett
At least some Apples program the GPU into a state that wedges the engine once userspace starts trying to perform accelerated operations. Executing the Atom init scripts gets the hardware back into a working state. The same hardware works fine when booted via BIOS emulation, so let's just execute the init scripts on Apples when we're using EFI.

2011-08-12drm/radeon: Allow panel preferred EDID to override BIOS native modeMatthew Garrett
We have two sources of information about panel capabilities on mobile radeon - the BIOS, which gives us a native mode, and the panel's preferred mode. In theory these two will always match, but there's some corner cases where the BIOS hasn't been fully initialised and so the native mode in it ends up with default values. However, if we get a panel with reasonable EDID, it's probably the case that the panel's preferred mode does actually represent the panel capabilities. This patch handles that case by replacing the native mode with the panel's preferred mode if the resolutions don't match. Systems without a valid internal panel EDID will still use the BIOS native mode.
