* gpu: nvgpu: use common nvgpu mutex/spinlock APIsDeepak Nibade2017-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using Linux APIs for mutex and spinlocks directly, use new APIs defined in <nvgpu/lock.h> Replace Linux specific mutex/spinlock declaration, init, lock, unlock APIs with new APIs e.g struct mutex is replaced by struct nvgpu_mutex and mutex_lock() is replaced by nvgpu_mutex_acquire() And also include <nvgpu/lock.h> instead of including <linux/mutex.h> and <linux/spinlock.h> Add explicit nvgpu/lock.h includes to below files to fix complilation failures. gk20a/platform_gk20a.h include/nvgpu/allocator.h Jira NVGPU-13 Change-Id: I81a05d21ecdbd90c2076a9f0aefd0e40b215bd33 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1293187 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: remove use of mutex_is_locked()Deepak Nibade2017-02-22
| | | | | | | | | | | | | | | | | | | mutex_is_locked() API is defined on Linux only and not on other OS like QNX. Hence remove use of this API for OS abstraction support to nvgpu. Instead of using mutex_is_locked(), use mutex_trylock() for same purpose Jira NVGPU-13 Change-Id: I542daf20a2294153da8e8bfe89e0dc0387297523 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1297184 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: Use timer API in gk20a codeAlex Waterman2017-01-18
| | | | | | | | | | | | | | | | | Use the timers API in the gk20a code instead of Linux specific API calls. This also changes the behavior of several functions to wait for the full timeout for each operation that can timeout. Previously the timeout was shared across each operation.

* gpu: nvgpu: Start re-organizing the HW headersAlex Waterman2017-01-11
| | | | | | | | | | | | | | | | | | | | | | | Reorganize the HW headers of gk20a. The headers are moved to a new directory: include/nvgpu/hw/gk20a And from the code are included like so: #include <nvgpu/hw/gk20a/hw_pwr_gk20a.h> This is the first step in reorganizing all of the HW headers for gm20b, gm206, etc. This is part of a larger effort to re-structure and make the driver more readable and scalable.
