Hi @jserv , I find that there are two inconsistencies in pcm_release state according to [the VirtIO 1.3 standard](https://docs.oasis-open.org/virtio/virtio/v1.3/csd01/virtio-v1.3-csd01.html#x1-56700014) in section 5.14.6.6.5.1: - The device MUST complete all pending I/O...

Hi @jserv , Let me report the current progress. I just implement the flush feature, and it actually flushes the I/O queue. I also observe that the sound device can...
Hi @jserv , I am going to report current progress in this comment. ## Findings The device always fails at `pcm_release` state after the second round of playing with the...
Hi @jserv , I am going to report current progress in this comment. ## Upgrade Linux Kernel to v6.7.12 In v6.7.12 (commit `fe981e67568c41de6caae25d70b5f203b94452cc`), it introduces ack callback to fulfill the...
Hi @jserv , I will report some progresses in these days in this comment. ## `aplay: pcm_write:2178: write error: Input/output error` After checking, I confirm that there is something funny...
Hi @xbasel and @zuiderkwast , I have done the acceleration of NEON for CRC32-C on ARM (particularly Armv7-A and Armv8-A 32-bit) with both lookup table and carry-less multiplication (reference: https://github.com/DLTcollab/sse2neon/pull/627/files)....
Hi @zuiderkwast , > IIUC, these techniques would only optimeze payloads of length 128 or longer. Do you have another experience? These techniques is for optimization utilizing both SIMD and...
Hi @zuiderkwast , Thanks for assigning this issue to me. I will list the tasks for the ease of tracking the progress. As such, I would like to ask the...
Thanks for the help of @zuiderkwast , I list the tasks for this issue: - [ ] Optimize CRC16 without any certain SIMD framework - Add unit tests as well....
