* 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: 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.
