* gpu: nvgpu: move cycle state buffer handler to linuxDeepak Nibade2017-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | We use dma_buf pointer cyclestate_buffer_handler in common code But since this is linux specific, we need to move this out of common code and into linux specific code Move dma_buf pointer cyclestate_buffer_handler from common channel code to struct nvgpu_channel_linux Fix all pointer accesses to this handle Move gk20a_channel_free_cycle_stats_buffer() to ioctl_channel.c since it is mostly linux specific And since gk20a_channel_free_cycle_stats_buffer() needs to be called while closing the channel, call it from nvgpu_channel_close_linux() Jira NVGPU-397 Jira NVGPU-415 Change-Id: Ifb429e49b8f7a1c9e2bc757f3efdd50b28ceca1f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1603909 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: move snapshot_client memory handling to linuxDeepak Nibade2017-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We right now store dmabuf fd and dma_buf pointer for gk20a_cs_snapshot_client But since dma_buf and all related APIs are linux specific, we need to remove them from common code and move them to linux specific code Add new linux specific structure gk20a_cs_snapshot_client_linux which includes struct gk20a_cs_snapshot_client and linux specific dma_buf pointer In gk20a_attach_cycle_stats_snapshot(), we first handle all dma_buf related operations and then call gr_gk20a_css_attach() Move gk20a_channel_free_cycle_stats_snapshot() to ioctl_channel.c In gk20a_channel_free_cycle_stats_snapshot(), we call gr_gk20a_css_detach() and then free up dma_buf in linux specific code We also need to call gk20a_channel_free_cycle_stats_snapshot() while closing the channel, so call it from linux specific nvgpu_channel_close_linux() Jira NVGPU-397 Jira NVGPU-415 Change-Id: Ida27240541f6adf31f28d7d7ee4f51651c6d3de2 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1603908 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: define error_notifiers in common codeDeepak Nibade2017-11-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the linux specific error_notifier codes are defined in linux specific header file <uapi/linux/nvgpu.h> and used in all the common driver But since they are defined in linux specific file, we need to move all the uses of those error_notifiers in linux specific code only Hence define new error_notifiers in include/nvgpu/error_notifier.h and use them in the common code Add new API nvgpu_error_notifier_to_channel_notifier() to convert common error_notifier of the form NVGPU_ERR_NOTIFIER_* to linux specific error notifier of the form NVGPU_CHANNEL_* Any future additions to error notifiers requires update to both the form of error notifiers Move all error notifier related metadata from channel_gk20a (common code) to linux specific structure nvgpu_channel_linux Update all accesses to this data from new structure instead of channel_gk20a Move and rename below APIs to linux specific file and declare them in error_notifier.h nvgpu_set_error_notifier_locked() nvgpu_set_error_notifier() nvgpu_is_error_notifier_set() Add below new API and use it in fifo_vgpu.c nvgpu_set_error_notifier_if_empty() Include <nvgpu/error_notifier.h> wherever new error_notifier codes are used NVGPU-426 Change-Id: Iaa5bfc150e6e9ec17d797d445c2d6407afe9f4bd Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1593361 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: use submit callback only in linux codeKonsta Holtta2017-11-22
| | | | | | | | | | | | | | | | | Move the implementation for channel job update callbacks that is based on Linux specific work_struct usage to Linux-specific code. This requires a bit of extra work for allocating OS-specific priv data for channels which is also done in this patch. The priv data will be used more when more OS-specific features are moved.

* gpu: nvgpu: support tuning per-ch deterministic optsKonsta Holtta2017-11-06
| | | | | | | | | | | | | | | | Add a new ioctl NVGPU_GPU_IOCTL_SET_DETERMINISTIC_OPTS to adjust deterministic options on a per-channel basis. Currently, the only supported option is to relax the no-railgating requirement on open deterministic channels. This also disallows submits on such channels, until the railgate option is reset.

* 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>
