Ben Skeggs	d1fb887a08	drm/nouveau/nv50-: separate CHANNEL_GPFIFO handling out from CHANNEL_DMA ... Primarily a cleanup to allow for changes in newer CHANNEL_GPFIFO classes to be more easily implemented. Compared to the prior implementation, this submits userspace push buffer segments as subroutines and uses the NV_RAMUSERD_TOP_LEVEL_GET registers to track the main (kernel) push buffer progress. Fixes a number of sporadic failures seen during piglit runs.

Ben Skeggs	2853ccf092	drm/nouveau/kms/nv50-: wrap existing command submission in nvif_push interface ... This commit pulls in a bunch of new push buffer macros which are able to support NVIDIA's class headers, and provide more useful debug output and error checking (compile-time, where possible) than we had previously. Will incrementally transition each function over to the unified interfaces. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>	2020-07-24 18:50:51 +10:00
