**Describe the bug** On one TGLU SDW device (jf-tglu-sku0a3e-sdw-01), we observed that HDA controller reset failure and DSP failed to probe after system boot. There's no WOV pipeline in the...
we currently only support the isochronous mode for 48kHz DAIs. If we want to send data at a different rate, we'll need to use the TX-controlled mode. It's supported by...
The kernel prints the following errors for a failed IPC commands ``` [ 123.853034] sof-audio-pci 0000:00:1f.3: ipc tx: 0x60010000: GLB_STREAM_MSG: PCM_PARAMS [ 123.853531] sof-audio-pci 0000:00:1f.3: error: ipc error for 0x60010000...
**Is your feature request related to a problem? Please describe.** On systems with multiplexed GPU and vga-switcheroo enabled in kernel: https://01.org/linuxgraphics/gfx-docs/drm/gpu/vga-switcheroo.html ... the Intel i915 graphics may be switched off...
What I have observed is that on CML/CNL platforms, running below commands will crash the whole system: 1. echo on > /sys/bus/pci/devices/0000\:00\:1f.3/power/control 2. cd /sys/kernel/debug/sof 3. hexdump hda (or dsp)...
Looking at `snd_sof_fw_parse_ext_data()` https://github.com/thesofproject/linux/blob/6da19674c8bf7ddf5af94c36b1d50a2ab5c35a29/sound/soc/sof/loader.c#L89 it parses firmware `fw_ready()` IPC message. While doing that it seems to unconditionally trust the correctness of data that has been read from the firmware, e.g....
We really need to have a watchdog-like mechanism where the host driver can detect the DSP is no longer responding and recover by reinitializing the hardware and notify apps.
When the firmware gets stuck or unresponsive (IPC timeouts), the driver just bails out and the only way to recover is to reboot. That's not acceptable for a number of...
on a stock Fedora34 (kernel v5.11.10) with SOF enabled, UCM endpoints are not detected. Gnome settings app does not show any output/input. Spotify starts but there is nothing progressing/playing. Updating...
Add logic to program LCTL in case clocks are not set up. Patch "ALSA: hda - set intel audio clock to a proper value" in non-DSP legacy driver
