* gpu: nvgpu: remove fence dependency trackingKonsta Holtta2017-04-11
| | | | | | | | | | | | | | | | | | | | In preparation for better abstraction in job synchronization, drop support for the dependency fences tracked via submit pre-fences in semaphore-based syncs. This has only worked for semaphores, not nvhost syncpoints, and hasn't really been used. The dependency was printed in the sync framework's sync pt value string. Remove also the userspace-visible gk20a_sync_pt_info which is not used and depends on this feature (providing a duration since the dependency fence's timestamp).

* gpu: nvgpu: wait for engine idle in shutdownDeepak Nibade2017-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_pm_shutdown(), we do not check return value of gk20a_pm_prepare_poweroff In some cases it is possible that gk20a_pm_prepare_poweroff() returns -EBUSY (this could happen if engines are busy) so we don't clean up s/w state and directly trigger GPU railgate In case some interrupt is triggered simultaneously we try to access a register while GPU is already railgated This leads to a hard hang in nvgpu shutdown path Make below changes in shutdown sequence to fix this: - check return value of gk20a_wait_for_idle() - disable activity on all engines with gk20a_fifo_disable_all_engine_activity() - ensure engines are idle with gk20a_fifo_wait_engine_idle() - check return value of gk20a_pm_prepare_poweroff() - check return value of gk20a_pm_railgate() Add a print when we bail out early in case GPU is already railgated Move to use new nvgpu_info/err() log messages instead of dev_*() messages Bug 200281010 Change-Id: I2856f9be6cd2de9b0d3ae12955cb1f0a2b6c29be Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1454658 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

Then there's the function name which is is right justified and post-fixed with a line number. This keeps all statements lined up so long as the function name does not exceed the length of characters alloted for function names (33 currently). Lines are also left justified with 4 available spaces since there are currently no source files with over 9999 lines. The type of message (DBG, WRN, ERR) is then printed in brackets. Finally there's whatever message is to be printed. The new API will be largely the same except there will be an additional print of the GPU that the message has originated from in order to help debug cases where both an iGPU and dGPU are active. Also the implicit newline added in the legacy API has been removed. This is inline with essentially every other print function in the C world. There are numerous places where '\n' is added despite it not being needed which results in log files being littered with blank lines. This makes the logs much harder to read. Bug ...

* gpu: nvgpu: use NO_KERNEL_MAPPING for default vidmemKonsta Holtta2017-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 8f3875393e7a6bd0fc03afdb1fa99b7e33b71576 ("abstract away dma alloc attrs") added an implicit NVGPU_DMA_NO_KERNEL_MAPPING for the explicit vidmem buffer allocation path. The default allocation api that chooses vidmem or sysmem based on available support still passed a zero flag and produced a warning when the flag should have been there. Force the NO_KERNEL_MAPPING flag on currently via the default-allocator api. Commit 8a15e02ca92b83aa5a216ea9cd42680373212ecd ("gpu: nvgpu: add NO_KERNEL_MAPPING for alloc_map_vid") did the same for flagless alloc-and-map calls but this default alloc-only call got overlooked. Also, store the flags in the mem_desc during allocation, just like in the sysmem allocator, to be checked during freeing.

| | | | | | | | | | | | | | | | | | | Move code that touches host registers and instance block to fifo HAL. This involves adding HAL ops for the fifo HAL functions that get called from outside fifo. This clears responsibility of channel by leaving it only managing channels in software and push buffers. channel had member ramfc defined, but it was not used, to remove it. pbdma_acquire_val consisted both of channel logic and hardware programming. The channel logic was moved to the caller and only hardware programming was moved.
