* gpu: nvgpu: take power refcount in gk20a_cde_convert()Deepak Nibade2017-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a gk20a_busy() call in gk20a_buffer_convert_gpu_to_cde() and we again call gk20a_busy() in gk20a_submit_channel_gpfifo() If gk20a_do_idle() is triggered in between these two calls, then this leads to a deadlock and results in idle failure Hence to avoid this take power refcount in a more fine-grained way i.e. in gk20a_cde_convert() instead of taking in gk20a_buffer_convert_gpu_to_cde() Keep gk20a_cde_execute_buffer() out of the gk20a_busy()/ gk20a_idle() pair since we take power refcount in submit path anyways Add correct error handling path in gk20a_cde_convert() Bug 200287073 Change-Id: Iffea2d4c03f42b47dbf05e7fe8fe2994f9c6b37c Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1324329 (cherry picked from commit ce057d784d40a6ce57e892d58e211ed2fd9826f8) Reviewed-on: http://git-master/r/1320408 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | In gk20a_cde_convert(), we hold cde_app.mutex almost for everything which is unnecessary Also, this causes a deadlock scenario when gk20a_do_idle() is called In some cases it is possible that Thread 1 holds the lock and is trying to power on GPU, and Thread 2 is trying to power off GPU and then grab cde_app.mutex to cleanup GPU state To fix this, grab the mutex only for gk20a_cde_get_context() and then release it Bug 200287073 Change-Id: Ic4856604652d0d4024abdeb5c2f8f03910c601a5 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1324328 (cherry picked from commit 3c8eef0d0e9ef3307e2792e3e127c10f3ff118a7) Reviewed-on: http://git-master/r/1322030 GVS: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

* gpu: nvgpu: abstract away dma alloc attrsKonsta Holtta2017-03-21
| | | | | | | | | | | | | | | | | | | | | | | | Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but define nvgpu-internal flags for no kernel mapping, force contiguous, and read only modes. Store the flags in the allocated struct mem_desc and only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS abstraction. Rename the notion of attr to flags. Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers allocated via gk20a_gmmu_alloc_vid for consistency. Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr parameter accidentally.

| | | | | | | | | | | | | | | | | | | | | | Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary since the natural free function name for this is nvgpu_kfree() but that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent patch). This API exists becasue not all allocation sizes can be determined at compile time and in some cases sizes may vary across the system page size. Thus always using kmalloc() could lead to OOM errors due to fragmentation. But always using vmalloc() is wastful of memory for small allocations. This API tries to alleviate those problems.
