Detailed Description
struct drm_panthor_queue_submit - Job submission arguments.
This is describing the userspace command stream to call from the kernel command stream ring-buffer. Queue submission is always part of a group submission, taking one or more jobs to submit to the underlying queues.
Member Data Documentation
◆ latest_flush
| __u32 drm_panthor_queue_submit::latest_flush |
@latest_flush: FLUSH_ID read at the time the stream was built.
This allows cache flush elimination for the automatic flush+invalidate(all) done at submission time, which is needed to ensure the GPU doesn't get garbage when reading the indirect command stream buffers. If you want the cache flush to happen unconditionally, pass a zero here.
Ignored when stream_size is zero.
◆ pad
| __u32 drm_panthor_queue_submit::pad |
@pad: MBZ.
◆ queue_index
| __u32 drm_panthor_queue_submit::queue_index |
@queue_index: Index of the queue inside a group.
◆ stream_addr
| __u64 drm_panthor_queue_submit::stream_addr |
@stream_addr: GPU address of the command stream to execute.
Must be aligned on 64-byte.
Can be zero is stream_size is zero too.
◆ stream_size
| __u32 drm_panthor_queue_submit::stream_size |
@stream_size: Size of the command stream to execute.
Must be 64-bit/8-byte aligned (the size of a CS instruction)
Can be zero if stream_addr is zero too.
When the stream size is zero, the queue submit serves as a synchronization point.
◆ syncs
| struct drm_panthor_obj_array drm_panthor_queue_submit::syncs |
@syncs: Array of struct drm_panthor_sync_op sync operations.
