* gpu: nvgpu: Add CHANNEL_SETUP_BIND IOCTLDebarshi Dutta2019-08-15
| | | | | | | | | | | | | | | | | | | | | | | | For a long time now, the ALLOC_GPFIFO_EX channel IOCTL has done much more than just gpfifo allocation, and its signature does not match support that's needed soon. Add a new one called SETUP_BIND to hopefully cover our future needs and deprecate ALLOC_GPFIFO_EX. Change nvgpu internals to match this new naming as well.

* gpu: nvgpu: rename has_timedout and make it thread safeSeema Khowala2019-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently has_timedout variable is protected by wmb at places where it is being set and there is no correspoding rmb whenever has_timedout variable is read. This is prone to errors for concurrent execution. This change is supposed to fix this issue. Rename has_timedout variable of channel struct to ch_timedout. Also to avoid rmb every time ch_timedout is read, ch_timedout_spinlock is added to protect ch_timedout variable for taking care of concurrent execution.

* gpu: nvgpu: move header location of gk20a.hDebarshi Dutta2018-09-25
| | | | | | | | | | | | | | | | | | | | | | | 1) Update header path of gk20a.h files present in os/ to <nvgpu/gk20a.h> 2) os_fence_android_sema.c indirectly was dependent on gk20a.h via semaphore.h.

* gpu: nvgpu: Update Linux side VM code for API solidificationAlex Waterman2018-06-22
| | | | | | | | | | | | | | | | | | | | | | Update the Linux specific code to match the MM API docs in the previous patch. The user passed page size is plumbed through the Linux VM mapping calls but is ultimately ignored once the core VM code is called. This will be handled in the next patch. This also adds some code to make the CDE page size picking happen semi-intelligently. In many cases the CDE buffers can be mapped with large pages.

* gpu: nvgpu: add submit entry points for kernel and ioctlKonsta Holtta2018-06-20
| | | | | | | | | | | | | | | | gk20a_submit_channel_gpfifo() supports reading the gpfifo entries from either a kernel buffer or an userspace buffer in an ioctl. Add two separate entry points: one for the ioctl and another for any other kernel use. This shortens the function prototypes and simplifies and clarifies the call sites slightly.
