* gpu: nvgpu: move channel_sync_gk20a.* to common directoryDebarshi Dutta2018-09-18
| | | | | | | | | | | | | | | | | | | | 1) Move channel_sync_gk20a.* from gk20a/ to common/ directory as they donot program any hardware registers. Also as an add-on rename channel_sync_gk20a.* to channel_sync.* and update the headers in required files. 2) Rename the struct gk20a_channel_sync to struct nvgpu_channel_sync. Also, corresponding syncpt and semaphore versions of the struct alongwith related methods are renamed by removing "gk20a" from their names and adding "nvgpu". 3) Add misra-c cleanups Jira NVGPU-1086 Change-Id: I4e0e21803ca3858dd7a5fc4d2454dba1f1bfcecd Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1812594 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | To finish OS unification of the submit path, move the gk20a_submit_channel_gpfifo* functions to a file that's accessible also outside Linux code. Also change the prefix of the submit functions from gk20a_ to nvgpu_.

* gpu: nvgpu: abstract away ioctl gpfifo readKonsta Holtta2018-06-20
| | | | | | | | | | | | | | | | | | | The biggest remaining Linuxism in the submit path is the copy_from_user() calls for reading the gpfifo entries to the HW-visible buffer. Abstract away the copy of one such segment starting at some offset and keep the wraparound logic and vidmem proxy in the core submit path.

* 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.
