* 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>
* gpu: nvgpu: hold mutex to get cde context onlyDeepak Nibade2017-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.

| | | | | | | | | | | | | | | | | | In the timers code a macro was using __builtin_return_address(0) when it should have been using _THIS_IP_. __builtin_return_address(0) will cause the timers code to print the return address of the function that calls the timers code. This isn't actually useful, of course. A user actually cares about where the timers code call comes from which is easily obtained with _THIS_IP_.

| | | | | | | | | | | | | | | | Read fuse values from GPU's own fuse registers instead of Tegra fuse registers whenever possible. This reduces the number of dependencies to Linux fuse code. Some fuses do not have a corresponding register in GPU, so they're left as is.
