Linux Firmware amdgpu Daily

Daily updates of amdgpu firmware from the kernel repo, added into the normal ubuntu linux-firmware package.

Inspired by: https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-19.10-Radeon-RX-5700
Because on 2020-10-21, ubuntu 20.04 was four releases behind on firmware for navi10 cards (20.10, 20.20, 20.30, 20.40).

I've been using this on focal since December 2020, and haven't heard of anyone having problems with it. It should work on 21.04 hirsute, and 21.10 impish. 20.10 groovy has been EOLed, so launchpad won't build packages for it anymore.

This bug makes these an unnecessary pain to maintain. https://bugs.launchpad.net/launchpad/+bug/1908006

To verify the contents of this PPA are identical to manually installing the upgraded firmware:

These instructions assume that all files in /lib/firmware are installed from the lib-firmware package. You should check which packages actually need to be reinstalled, with "dpkg -S /lib/firmware", before deleting it.

apt update && apt dist-upgrade
mkdir ~/linux-firmware.tmp
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git ~/linux-firmware.tmp/linux-firmware
cd /lib
mv firmware firmware.bak
apt reinstall linux-firmware # get rid of cruft
rm -r firmware/amdgpu/
cp -a ~/linux-firmware.tmp/linux-firmware/amdgpu/ firmware/
mv firmware firmware.goal
add-apt-repository ppa:darxus/linux-firmware-amdgpu-daily
apt update && apt dist-upgrade
# this should not output anything, unless upstream has updated in the last day:
diff -r firmware.goal firmware

To uninstall this PPA and revert to the normal linux-firmware package:

ppa-purge ppa:darxus/linux-firmware-amdgpu-daily

I have another PPA that updates everything in this package that comes from the upstream kernel linux-firmware repo: https://code.launchpad.net/~darxus/+archive/ubuntu/linux-firmware-daily/

The AMD firmware release notes mentioned this PPA from February to April 2021, then they removed the entire "Using the Upstream version" section, which linked to this:
