* gpu: nvgpu: Add and move FECS trace flagvishnu Reddy2017-03-02
| | | | | | | | | | | | | | | | Added fecs trace characteristic flag to vgpu to determine for platform support Also moved fecs flag from ctxsw init to fecs init for native linux. This makes flag init uniform across both platforms.

* gpu: nvgpu: do not flush FECS record on engine resetThomas Fleury2016-08-29
| | | | | | | | | | | | | | | | | | | | | | | Flushing timestamp record method can fail in case FECS is not processing the main method queue. In particular, this occurs in case of ctxsw timeout, where we process fifo sched interrupts from the host, but FECS is still waiting for idle (grWFI). In such scenario, this adds huge delay in fifo recovery procedure (timeout on FECS method). Since flushing the last (incomplete) record from FECS would only be useful in that case (context switch ongoing), remove flush operation on engine reset. Note that an explicit ENGINE_RESET event (with pid) is inserted in user-facing ctxsw buffer on engine reset.

* gpu: nvgpu: Add support for FECS ctxsw tracingAnton Vorontsov2016-03-23
bug 1648908 This commit adds support for FECS ctxsw tracing. Code is compiled conditionnaly under CONFIG_GK20_CTXSW_TRACE. This feature requires an updated FECS ucode that writes one record to a ring buffer on each context switch. On RM/Kernel side, the GPU driver reads records from the master ring buffer and generates trace entries into a user-facing VM ring buffer. For each record in the master ring buffer, RM/Kernel has to retrieve the vmid+pid of the user process that submitted related work. Features currently implemented: - master ring buffer allocation - debugfs to dump master ring buffer - FECS record per context switch (with both current and new contexts) - dedicated device for ctxsw tracing (access to VM ring buffer) - SOF generation (and access to PTIMER) - VM ring buffer allocation, and reconfiguration - enable/disable tracing at user level - event-based trace filtering - context_ptr to vmid+pid mapping - read system call for ctxsw dev - mmap system call for ctxsw dev (direct access to VM ring buffer) - poll system call for ctxsw dev - save/restore register on ELPG/CG6 - separate user ring from FECS ring handling Features requiring ucode changes: - enable/disable tracing at FECS level - actual busy time on engine (bug 1642354) - master ring buffer threshold interrupt (P1) - API for GPU to CPU timestamp conversion (P1) - vmid/pid/uid based filtering (P1) Change-Id: I8e39c648221ee0fa09d5df8524b03dca83fe24f3 Signed-off-by: Thomas Fleury <tfleury@nvidia.com> Reviewed-on: http://git-master/r/1022737 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
