* 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: Disable IRQs only if enabledAlex Waterman2017-02-21
| | | | | | | | | | | | | | | | | In the PCI init/de-init code only disable IRQs if they were enabled. The enable happens in the common power_on code. The PCI routines could both be called without the common power_on code being called which causes an extra disable to happen.

| | | | | | | | | | | | | | | | | In two places we used broadcast register as base, but added the unicast offset to it. This causes the write to go well beyond valid register range.

| | | | | | | | | | | | | | | | | | | | | | | Move semaphore_gk20a.c drivers/gpu/nvgpu/common/ since the semaphore code is common to all chips. Move the semaphore_gk20a.h header file to drivers/gpu/nvgpu/include/nvgpu and rename it to semaphore.h. Also update all places where the header is inluced to use the new path. This revealed an odd location for the enum gk20a_mem_rw_flag. This should be in the mm headers. As a result many places that did not need anything semaphore related had to include the semaphore header file. Fixing this oddity allowed the semaphore include to be removed from many C files that did not need it.

* gpu: nvgpu: Move kmem_caches to allocatorAlex Waterman2017-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using a single static kmem_cache for each type of data structure the allocators may want to allocate each allocator now has its own instance of the kmem_cache. This is done so that each GPU driver instance can accurately track how much memory it is using. In order to support this on older kernels a new NVGPU API has been made, nvgpu_kmem_cache_create(struct gk20a *g, size_t size) To handle the possibility that caches cannot be created with the same name. This patch also fixes numerous places where kfree() was wrongly used to free kmem_cache allocs.

* gpu: nvgpu: Simplify ref-counting on VMsAlex Waterman2017-02-07
| | | | | | | | | | | | | | | | | | | | Simplify ref-counting on VMs: take a ref when a VM is bound to a channel and drop a ref when a channel is freed. Previously ref-counts were scattered over the driver. Also the CE and CDE code would bind channels with custom rolled code. This was because the gk20a_vm_bind_channel() function took an as_share as the VM argument (the VM was then inferred from that as_share). However, it is trivial to abtract that bit out and allow a central bind channel function that just takes a VM and a channel.
