This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "A pseudo Operating System for the Dreamcast.".
The branch, master has been updated
via e1c2a4a3124fb40019c1dd4857e0f4a5d1641339 (commit)
from b8a7ada874b94303dca9288ecb0457ef1083051b (commit)
Those revisions listed above that are new to this repository have

commit e1c2a4a3124fb40019c1dd4857e0f4a5d1641339
Author: Ruslan Rostovtsev <sw...@21...>
Date: Fri Dec 29 09:16:54 2023 +0700
Fixes and improvements for Store Queues, Sound and PVR. (#385)
* Fixed snd_pcm16_split_sq().
Also few minor fixes for streams.
* Minor fixes for SPU memload, memread and memset.
* Added dcache_wback_sq() and fix sq_set32().
* Apply suggestions from code review
* Updated authors and remove unused declaration.
Also fix suggestions.
* Re-design Store Queues i/f, improved PVR SQ, ...
- Fixed PVR DMA bus selection.
- Do not disable IRQ due SQ transfer over G2 bus.
* Manage Store Queues for PVR Direct Rendering.
* Added sq_flush() and hide QACR0/1 regs.
* Re-organize PVR memory destination. Add DMA over Root bus.
* Added pvr_sq_set32() and some fixes.
* Fixed PVR examples with Direct Render.
* Fixed SET_QACR_REGS for TA bus.
* Get back single destination for SQ.
Also don't wait SQ on lock.
* Added spu_memset_sq() and minor fixes.
* Updated YUV examples.
* Improved bus selection for TA->VRAM.
* Updated description of PVR and TA memory addresses.
Also remove rootbus/sysbus because need implement CH0 PVR i/f DMA first.
* Use pvr_sq_load() for pvr textures.
Also minor fixes.
* Updated yuv420 example to use SQ better.
* Fixed PVR Direct Rendering.
And removed unused param from PVR state.
