Comment 0 for bug 1939986

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
