* gpu: nvgpu: Add context reset at golden context initTerje Bergstrom2016-06-04
| | | | | | | | | | | | | | | | | | Part of golden context initialization is in powerup sequence, and part done as part of first channel creation. The sequence is missing a context reset, which causes initialization of golden context to fail on dGPU. Just moving the code to golden context initialization does not work, because iGPU can be rail gated, and part of the sequence is required in GPU boot. Thus a part of context initialization is replicated to golden context init after a context reset.

* gpu: nvgpu: fix TSG abort sequenceDeepak Nibade2016-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_fifo_abort_tsg(), we loop through channels of TSG and call gk20a_channel_abort() for each channel This is incorrect since we disable and preempt each channel separately, whereas we should disable all channels at once and use TSG specific API to preempt TSG Fix this with below sequence : - gk20a_disable_tsg() to disable all channels - preempt tsg if required - for each channel in TSG - set has_timedout flag - call gk20a_channel_abort_clean_up() to clean up channel state Also, separate out common gk20a_channel_abort_clean_up() API which can be called from both channel and TSG abort routines In gk20a_channel_abort(), call gk20a_fifo_abort_tsg() if the channel is part of TSG Add new argument "preempt" to gk20a_fifo_abort_tsg() and preempt TSG if flag is set Bug 200205041 Change-Id: I4eff5394d26fbb53996f2d30b35140b75450f338 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1157190 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* | gpu: nvgpu: add PRAMIN support for mem accessorsKonsta Holtta2016-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support vidmem, implement a way to access buffers via the PRAMIN window instead of just kernel-mapped sysmem buffers for iGPU as of now. Depending on the buffer aperture, choose between the two access types in the buffer memory accessor functions. vmap()/vunmap() pairs are no-ops for buffers that can't be cpu-mapped. Two uses of DMA_ATTR_READ_ONLY are removed in the ucode loading path to support writing to them too via the indirection in addition to cpu.

| | | | | | | | | | | | | | | | | | | | | | | | FECS trace are currently collected using periodic polling every 16.66 ms. Whenever polling thread finds some events from FECS, it generates a SOF event with current PTIMER value. These events may introduce out of order timestamps, and extra processing would be required in driver to insert them in the right order. This change removes SOF event generation, as they is currently no use case for them.
