Ben Skeggs	468fae7bb0	drm/nouveau/fifo: add cgrp, have all channels be part of one ... Engine context tracking will move to nvkm_cgrp in later commits, so we create SW-only channel groups on HW without support for them. - switches to nvkm_chid for TSG/channel ID allocation Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>	2022-11-09 10:44:47 +10:00
Ben Skeggs	800ac1f8d7	drm/nouveau/fifo: add chid allocator ... We need to be able to allocate TSG IDs as well as channel IDs, also, Ampere has per-runlist channel IDs. - holds per-ID private data, which will be used for/to protect lookup - holds an nvkm_event which will be used for events tied to IDs - not used yet beyond setup, and switching use of "fifo->nr - 1" for channel ID mask to "chid->mask" Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>	2022-11-09 10:44:47 +10:00
