Hi all, While debugging some of my work, I find it difficult to relate the aubinator decoded instructions to the part of the API that actually emitted those packets (especially with Anv that records batches of instructions per pipeline and just dumps them out in a batchbuffer later) .
This series introduce a new debug parameter (INTEL_DEBUG=batch-messages) that will require the driver to emit debug messages in the command stream. For now they're implemented using MI_NOOP. When the "Identification Number Register Write Enable" field is set to false, the 21 bits "Identification Number" can be used for stuff 3 ascii characters. For now there are only a few debug messages but you probably want to write your own depending what you're debbuging. Patch 2 also implement the reading back of those messages in either aubinator, aubinator_error_decode or while debugging with INTEL_DEBUG=batch. Looking forward to comments!
