2012-10-16lib tools traceevent: Add back pevent assignment in __pevent_parse_format()Steven Rostedt
Even though with the change of commit commit 2b29175 "tools lib traceevent: Carve out events format parsing routine", allowed __pevent_parse_format() to parse an event without the need of a pevent handler, the event still needs to assign the pevent handed to it. There's no problem with assigning it if the pevent is NULL, as the event->pevent would be NULL without the assignment. But function parsing handlers may be assigned to the pevent handler to help in parsing the event. If there's no pevent then there would not be any function handlers, but if the pevent isn't assigned first before parsing the event, it wont honor the function handlers that were assigned. Worse yet, the current code crashes if an event has a function that it tries to parse. For example: # perf record -e scsi:scsi_dispatch_cmd_timeout Segmentation fault (core dumped) This happens because the scsi_dispatch_cmd_timeout event format has the following: scsi_trace_parse_cdb(p, __get_dynamic_array(cmnd), REC->cmd_len) which hasn't been defined by the pevent code.

2012-10-16perf: Require exclude_guest to use PEBS - kernel side enforcementPeter Zijlstra
Intel PEBS in VT-x context uses the DS address as a guest linear address, even though its programmed by the host as a host linear address. This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine.

2012-10-16perf tool: Precise mode requires exclude_guestDavid Ahern
Summary of events per Peter: "Intel PEBS in VT-x context uses the DS address as a guest linear address, even though its programmed by the host as a host linear address. This either results in guest memory corruption and or the hardware faulting and 'crashing' the virtual machine. Therefore we have to disable PEBS on VT-x enter and re-enable on VT-x exit, enforcing a strict exclude_guest. AMB IBS does work but doesn't currently support exclude_* at all, setting an exclude_* bit will make it fail." This patch handles userspace perf command, setting the exclude_guest attribute if precise mode is requested, but only if a user has not specified a request for guest or host only profiling (G or H attribute). Kernel side AMD currently ignores all exclude_* bits, so there is no impact to existing IBS code paths. Robert Richter has a patch where IBS code will return EINVAL if an exclude_* bit is set. When this goes in it means use of :p on AMD with IBS will first fail with EINVAL (because exclude_guest will be set). Then the existing fallback code within perf will unset exclude_guest and try again. The second attempt will succeed if the CPU supports IBS profiling.

2012-10-15xtensa: copy_thread with CLONE_VM must not copy live parent AR windowsMarc Gauthier
When doing a fork (new VM), the new task has a mirror image of the parent's stack, so keeps the same live register windows etc. However when doing a clone with CLONE_VM, keeping the same VM (eg. when creating a new thread), the child starts afresh on a new stack -- it cannot share any part of the parent stack. It especially cannot have the same live AR windows as the parent, otherwise it will overwrite the parent stack on overflow, likely causing corruption. (and so it did...) Effectively, the register windows need to be spilled. Turns out it's much easier to simply not copy parent register windows when CLONE_VM is set.

Based on Dmitries work, but splitting the code into page directory and page table handling makes it far more readable and (hopefully) more reliable. Allocations of page tables are made from the SA on demand, that should still work fine since all page tables are of the same size. Also using the fact that allocations from the SA are mostly continuously (except for end of buffer wraps and under very high memory pressure) to group updates send to the chipset specific code into larger chunks. v3: mostly a rewrite of Dmitries previous patch. v4: fix some typos and coding style Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Tested-by: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2012-10-15drm/radeon: allocate PPLLs from low to highAlex Deucher
The order shouldn't matter, but there have been problems reported on certain older asics. This behaves more like the original code before the PPLL allocation rework. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Markus Trippelsdorf <markus@trippelsdorf.de>
