* gpu: nvgpu: Move Linux files away from commonTerje Bergstrom2018-06-15
| | | | | | | | | | | | | | | Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.

* gpu: nvgpu: drop force_need_sync_fence in submit pathKonsta Holtta2018-05-18
| | | | | | | | | | | | | | | | For CDE work a sync fence is always requested, but kernel does not need it and submit flags from userspace will be passed to the submit function in cde path so a sync fence will get created if necessary. To reduce some complexity, remove the explicit boolean in favor of just NVGPU_SUBMIT_FLAGS_SYNC_FENCE.

* gpu: nvgpu: Add conversion function for uapi submit gpfifo flagsSourab Gupta2018-04-11
| | | | | | | | | | | | | | | | | | The submit gpfifo flags are splattered everywhere inside the nvgpu code. Though the usage is inside nvgpu Linux code only, still it needs to be gotten rid of and replaced with the defines present in common code.

* gpu: nvgpu: remove usage of nvgpu_gpfifoSourab Gupta2018-04-11
| | | | | | | | | | | | | | | | | | | Remove the usage of nvgpu_gpfifo splattered across nvgpu, and replace with a struct defined in common code. The usage is still inside Linux, but this helps the subsequent unification efforts, e.g. to unify the submit path.

* gpu: nvgpu: ce: store fences in a separate arrayKonsta Holtta2018-01-26
| | | | | | | | | | | | | | | | | | | | Simplify the copyengine code massively by storing the job post fence pointers in an array of fences instead of mixing them up in the command buffer memory. The post fences are used when the ring buffer of a context gets full and we need to wait for the oldest slot to free up.

| | | | | | | | | | | | | | | | | | | | | | | Simplify the copyengine code by deleting support for the ce_event_callback feature that has never been used. Similarly, create a channel without the finish callback to get rid of that Linux dependency, and delete the finish callback function as it now serves no purpose. Delete also the submitted_seq_number and completed_seq_number fields that are only written to.

* gpu: nvgpu: move submit path to linuxDeepak Nibade2017-11-02
Nvgpu submit path has a lot of dependency on Linux framework e.g. use of copy_from_user, use of structures defined in uapi/nvgpu headers, dma_buf_* calls for trace support etc Hence to keep common code independent of Linux code, move submit path to Linux directory Move below APIs to common/linux/channel.c trace_write_pushbuffer() trace_write_pushbuffer_range() gk20a_submit_prepare_syncs() gk20a_submit_append_priv_cmdbuf() gk20a_submit_append_gpfifo() gk20a_submit_channel_gpfifo() Move below APIs to common/linux/ce2.c gk20a_ce_execute_ops() Define gk20a_ce_execute_ops() in common/linux/ce2.c, and declare it in gk20a/ce2_gk20a.h since it is needed in common/mm code too Each OS needs to implement this API separately gk20a_channel_alloc_gpfifo() use sizeof(nvgpu_gpfifo) to get size of one gpfifo entry, but structure nvgpu_gpfifo is linux specific Define new nvgpu_get_gpfifo_entry_size() in linux specific code and use it in gk20a_channel_alloc_gpfifo() to get gpfifo entry size Each OS needs to implement this API separately Export some APIs from gk20a/ce2_gk20a.h and gk20a/channel_gk20a.h that are needed in linux code Jira NVGPU-259 Jira NVGPU-313 Change-Id: I360c6cb8ce4494b1e50c66af334a2a379f0d2dc4 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1586277 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
