Title:
Missing firmware files, in Ubuntu 20.04 LTS, for initramfs, when it
loads i915
Status in linux-firmware package in Ubuntu:
Invalid
Status in linux-firmware source package in Focal:
Fix Committed
Bug description:
[ Impact ]
The i915 driver in Focal HWE kernels (currently 5.11 and 5.13) needs
new firmware blobs. Without them, some users reported display/audio
issues when installing said kernel.
[ Test Case ]
1) Install linux-generic-hwe-20.04
2) echo 'i915' >> /etc/initramfs-tools/modules
3) update-initramfs -u
Which leads to multiple warnings:
W: Possible missing firmware <foo> for module i915
[Fix ]
Add missing firmware blobs from upstream linux-firmware.
[ Where Problems Could Occur ]
New closed-source firmware binaries, would could possibly go wrong? No
display with i915, kernel crashes.
[ Original Description ]
Dear all,
I can see that the linux-firmware is missing firmware files, in Ubuntu
20.04.1 LTS, for initramfs, when it loads i915.
Package: linux-firmware 1.187.15
It contains the following files, for the module i915:
i915/tgl_dmc_ver2_04.bin 2019-09-13 installed
i915/tgl_dmc_ver2_06.bin 2020-03-04 installed
i915/tgl_dmc_ver2_08.bin 2020-08-13 installed
i915/tgl_guc_35.2.0.bin 2019-11-06 installed
i915/tgl_huc_7.0.12.bin 2020-03-04 installed
i915/tgl_huc_7.0.3.bin 2019-11-06 installed
Package: linux-firmware
MUST at least contain the following files, for the module i915:
i915/tgl_huc_7.5.0.bin 2020-08-13 i915: Add HuC
firwmare v7.5.0 for TGL
as the module asks for it, during 'update-initramfs', to avoid:
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for module
i915
But it COULD also contain :
i915/tgl_dmc_ver2_12.bin 2021-07-28 i915: Add v2.12 DMC for TGL
i915/tgl_guc_49.0.1.bin 2020-11-24 i915: Add GuC firmware
v49.0.1 for all platforms
i915/tgl_guc_62.0.0.bin 2021-06-29 firmware/i915/guc: Add
GuC v62.0.0 for all platforms
i915/tgl_huc_7.9.3.bin 2021-06-29 firmware/i915/guc: Add
HuC v7.9.3 for TGL & DG1
Source:
$ modprobe --show-depends --ignore-install i915
...
insmod /lib/modules/5.10.0-1038-oem/kernel/drivers/gpu/drm/i915/i915.ko
$ modinfo -F firmware
/lib/modules/5.10.0-1038-oem/kernel/drivers/gpu/drm/i915/i915.ko
...
i915/tgl_dmc_ver2_08.bin
i915/tgl_guc_35.2.0.bin
i915/tgl_huc_7.5.0.bin
Actual result:
$ sudo update-initramfs -u
W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for module
i915
Expected result:
No Warning. and the firmware "i915/tgl_huc_7.5.0.bin" loaded for module i915
