* | 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>
