Built-in Intel Bluetooth device disappeared after booting Linux 6.7

by Ramses

I am running an alder lake i7 1260P with built-in bluetooth. This adapter always worked fine with no special config, but since I booted Linux 6.7, the device completely disappeared. There's no mention of bluetooth in the kernel or system logs, there's no device node, and there's no entry in lspci. When I boot the last working kernel again (6.6.10), the device also doesn't appear (even though it did before, see logs below). I also tried booting a ubuntu live ISO to exclude any configuration issues with my distro's (NixOS) kernel or such, and also there the device did not show up. I am not sure at all that this is related to the kernel, but I wouldn't know where else to look. I am including below my system logs (journalctl -g 'blue|Blue|Linux') showing the kernel version and the bluetooth related entries. As you can see, on 6.6.10 the bluetooth module got loaded, /dev/hci0 gets created, and user space sets up the bluetooth stack. The next boot entry is the first time I booted 6.7, and there's no mention of bluetooth at all in the logs. I tried to load the bluetooth module manually, which succeeds but doesn't create a device node. When I boot 6.6.10 again now, I get exactly the same as on 6.7. I don't know if the kernel could have done anything persistent to the device that makes that it doesn't get initialised anymore? I'm not sure how to debug this further, let me know if there's a way to get more detailed info in the kernel logs or such. Thanks, Ramses Logs with 6.6.10: -- Boot 7847b5595e1d40a8bf2624542e5fff74 -- jan 09 02:03:50 localhost kernel: Linux version 6.6.10 (nixbld@localhost) (gcc (GCC) 12.3.0, GNU ld (GNU Binutils) 2.40) #1-NixOS SMP PREEMPT_DYNAMIC Fri Jan 5 14:19:45 UTC 2024 jan 09 02:03:50 localhost kernel: SELinux: Initializing. jan 09 02:03:50 localhost kernel: usb usb1: Manufacturer: Linux 6.6.10 xhci-hcd jan 09 02:03:50 localhost kernel: usb usb2: Manufacturer: Linux 6.6.10 xhci-hcd jan 09 02:04:02 starbook kernel: Linux agpgart interface v0.103 jan 09 02:04:02 starbook kernel: mc: Linux media interface: v0.10 jan 09 02:04:02 starbook kernel: Bluetooth: Core ver 2.22 jan 09 02:04:02 starbook kernel: Bluetooth: HCI device and connection manager initialized jan 09 02:04:02 starbook kernel: Bluetooth: HCI socket layer initialized jan 09 02:04:02 starbook kernel: Bluetooth: L2CAP socket layer initialized jan 09 02:04:02 starbook kernel: Bluetooth: SCO socket layer initialized jan 09 02:04:03 starbook kernel: videodev: Linux video capture interface: v2.00 jan 09 02:04:03 starbook kernel: Intel(R) Wireless WiFi driver for Linux jan 09 02:04:03 starbook kernel: Bluetooth: hci0: Firmware timestamp 2023.42 buildtype 1 build 73111 jan 09 02:04:03 starbook kernel: Bluetooth: hci0: No support for _PRR ACPI method jan 09 02:04:03 starbook kernel: Bluetooth: hci0: Found device firmware: intel/ibt-0041-0041.sfi jan 09 02:04:03 starbook kernel: Bluetooth: hci0: Boot Address: 0x100800 jan 09 02:04:03 starbook kernel: Bluetooth: hci0: Firmware Version: 151-42.23 jan 09 02:04:03 starbook kernel: Bluetooth: hci0: Firmware already loaded jan 09 02:04:03 starbook kernel: pps_core: LinuxPPS API ver. 1 registered jan 09 02:04:04 starbook dbus-broker-launch[1265]: Ignoring duplicate name 'org.bluez.mesh' in service file '/nix/store/6dln0pmd1zb9xg4c81l3k08igxh98j0w-bluez-5.70/share/dbus-1/system-services/org.bluez.> jan 09 02:04:04 starbook dbus-broker-launch[1265]: Ignoring duplicate name 'org.bluez' in service file '/nix/store/6dln0pmd1zb9xg4c81l3k08igxh98j0w-bluez-5.70/share/dbus-1/system-services/org.bluez.servi> jan 09 02:04:04 starbook systemd[1]: Starting Bluetooth service... jan 09 02:04:04 starbook (uetoothd)[1275]: bluetooth.service: ConfigurationDirectory 'bluetooth' already exists but the mode is different.

[PATCH] block: Fix iterating over an empty bio with bio_for_each_folio_all

[PATCH v4 3/4] ASoC: codecs: lpass-wsa-macro: fix compander volume hack

by Johan Hovold

The LPASS WSA macro codec driver is updating the digital gain settings behind the back of user space on DAPM events if companding has been enabled. As compander control is exported to user space, this can result in the digital gain setting being incremented (or decremented) every time the sound server is started and the codec suspended depending on what the UCM configuration looks like. Soon enough playback will become distorted (or too quiet). This is specifically a problem on the Lenovo ThinkPad X13s as this bypasses the limit for the digital gain setting that has been set by the machine driver. Fix this by simply dropping the compander gain offset hack. If someone cares about modelling the impact of the compander setting this can possibly be done by exporting it as a volume control later. Note that the volume registers still need to be written after enabling clocks in order for any prior updates to take effect.

[PATCH v4 1/4] ASoC: codecs: wsa883x: fix PA volume control

by Johan Hovold

The PA gain can be set in steps of 1.5 dB from -3 dB to 18 dB, that is, in 15 levels. Fix the dB values for the PA volume control as experiments using wsa8835 show that the first 16 levels all map to the same lowest gain while the last three map to the highest gain. These values specifically need to be correct for the sound server to provide proper volume control. Note that level 0 (-3 dB) does not mute the PA so the mute flag should also not be set.

[PATCH] drm/i915/psr: Only allow PSR in LPSP mode on HSW non-ULT

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> On HSW non-ULT (or at least on Dell Latitude E6540) external displays start to flicker when we enable PSR on the eDP. We observe a much higher SR and PC6 residency than should be possible with an external display, and indeen much higher than what we observe with eDP disabled and only the external display enabled. Looks like the hardware is somehow ignoring the fact that the external display is active during PSR. I wasn't able to redproduce this on my HSW ULT machine, or BDW. So either there's something specific about this particular laptop (eg. some unknown firmware thing) or the issue is limited to just non-ULT HSW systems. All known registers that could affect this look perfectly reasonable on the affected machine. As a workaround let's unmask the LPSP event to prevent PSR entry except while in LPSP mode (only pipe A + eDP active). This will prevent PSR entry entirely when multiple pipes are active. The one slight downside is that we now also prevent PSR entry when driving eDP with pipe B or C, but I think that's a reasonable tradeoff to avoid having to implement a more complex workaround.
