ASoC: SOF: amd: Fix error code handling in psp_send_cmd()

2026-05-12T01:14:33+00:00

The smn_read_register() helper returns negative error codes on failure or the register value on success. When used with read_poll_timeout(), the return value is stored in the 'data' variable. Currently 'data' is declared as u32, which causes negative error codes to be cast to large positive values. This makes the condition 'data > 0' incorrectly treat errors as success. Fix by changing 'data' from u32 to int, matching the pattern used in psp_mbox_ready() which correctly handles the same helper function.

ALSA: compress_offload: Add 64-bit safe timestamp infrastructure

2025-09-08T07:33:24+00:00

The copied_total field in struct snd_compr_tstamp is a 32-bit value that can overflow on long-running high-bitrate streams, leading to incorrect calculations for buffer availablility. This patch adds a 64-bit safe timestamping mechanism. A new UAPI struct, snd_compr_tstamp64, is added which uses 64-bit types for byte counters. The relevant ops structures across the ASoC and core compress code are updated to use this new struct. ASoC drivers are updated to use u64 counters. Internal timestamps being u64 now, a compatibility function is added to convert the 64-bit timestamp back to the 32-bit format for legacy ioctl callers.

ASoC: SOF: amd: acp-loader: Use GFP_KERNEL for DMA allocations in resume context

2025-07-28T17:58:15+00:00

Replace GFP_ATOMIC with GFP_KERNEL for dma_alloc_coherent() calls. This change improves memory allocation reliability during firmware loading, particularly during system resume when memory pressure is high. Because of using GFP_KERNEL, reclaim can happen which can reduce the probability of failure. Fixes memory allocation failures observed during system resume with fragmented memory conditions. snd_sof_amd_vangogh 0000:04:00.5: error: failed to load DSP firmware after resume -12 Fixes: 145d7e5ae8f4e ("ASoC: SOF: amd: add option to use sram for data bin loading") Fixes: 7e51a9e38ab20 ("ASoC: SOF: amd: Add fw loader and renoir dsp ops to load firmware") Cc: stable@vger.kernel.org Signed-off-by: Muhammad Usama Anjum Link: https://patch.msgid.link/20250725190254.1081184-1-usama.anjum@collabora.com Signed-off-by: Mark Brown
