A debugfs node, /d/<gpu>/separate_fixed_allocs Controls this feature. To enable it: # echo <SPLIT_ADDR> > /d/<gpu>/separate_fixed_allocs Where <SPLIT_ADDR> is the address to do the split on in the GVA address range. This will cause the split to be made in all subsequent address space ranges that get created until it is turned off. To turn this off just echo 0x0 into the same debugfs node.

* | gpu: nvgpu: Add support for FECS ctxsw tracingAnton Vorontsov2016-03-23

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>
