* gpu: nvgpu: Direct GMMU PTE kind controlSami Kiminki2017-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow userspace to control directly the PTE kind for the mappings by supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX. In particular, in this mode, the userspace will tell the kernel whether the kind is compressible, and if so, what is the incompressible fallback kind. By supplying only the compressible kind, the userspace can require that the map kind will not be demoted to the incompressible fallback kind in case of comptag allocation failure. Add also a GPU characteristics flag NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct kind control is supported. Fix indentation of nvgpu_as_map_buffer_ex_args header comment.

* gpu: nvgpu: Implement PD packingAlex Waterman2017-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases page directories require less than a full page of memory. For example, on Pascal, the final PD level for large pages is only 256 bytes; thus 16 PDs can fit in a single page. To allocate an entire page for each of these 256 B PDs is extremely wasteful. This patch aims to alleviate the wasted DMA memory from having small PDs in a full page by packing multiple small PDs into a single page. The packing is implemented as a slab allocator - each page is a slab and from each page multiple PD instances can be allocated. Several modifications to the nvgpu_gmmu_pd struct also needed to be made to support this. The nvgpu_mem is now a pointer and there's an explicit offset into the nvgpu_mem struct so that each nvgpu_gmmu_pd knows what portion of the memory it's using. The nvgpu_pde_phys_addr() function and the pd_write() functions also require some changes since the PD no longer is always situated at the start of the nvgpu_mem. Initialization and cleanup of the page tables for each VM was slightly modified to work through the new pd_cache implementation. Some PDs (i.e the PDB), despite not being a full page, still require a full page for alignment purposes (HW requirements). Thus a direct allocation method for PDs is still provided. This is also used when a PD that could in principle be cached is greater than a page in size. Lastly a new debug flag was added for the pd_cache code.

* gpu: nvgpu: hold power ref for deterministic channelsKonsta Holtta2017-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support deterministic channels even with platforms where railgating is supported, have each deterministic-marked channel hold a power reference during their lifetime, and skip taking power refs for jobs in submit path for those. Previously, railgating blocked deterministic submits in general because of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time and more significantly because the gpu may need turning on which takes a nondeterministic and long amount of time. As an exception, gk20a_do_idle() can still block deterministic submits until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize needs do_idle, which conflicts with deterministic channels' requirement to keep the GPU on. This is documented in the ioctl header now. Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always set in the gpu characteristics now that it's supported. The only thing left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is the sync framework. Make the channel debug dump show which channels are deterministic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* gpu: nvgpu: debugging API updateAlex Waterman2017-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the debugging APIs in nvgpu to be more coherent and less dependent on Linux kernel APIs and data structures. The old API is maintained for backwards compatibility but the prints themselves are changed. The old API now prints stuff like this: [ 46.376077] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 508 [ 46.376242] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 509 [ 46.376359] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 510 [ 46.376466] nvgpu: gk20a_channel_suspend:3430 [DBG] suspend channel 511 [ 46.376604] nvgpu: gk20a_fifo_update_runlist_locked:3090 [DBG] runlist_id : 0, switch to new buffer 0x 4003a0000 [ 46.378348] nvgpu: gk20a_mm_l2_flush:5259 [DBG] l2_flush_dirty 0x2 [ 46.378562] nvgpu: clk_config_pll:170 [DBG] low_PL 1(div1), high_PL 2(div2) [ 46.378684] nvgpu: clk_config_pll:170 [DBG] low_PL 8(div8), high_PL 17(div17) Each line starts with 'nvgpu:' since this is the nvgpu driver. 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 ...
