I have a question, is there any way to compile Mesa by linking it to a custom libdrm folder? My system ships with an older version of the libdrm but I can compile 2.4.99 easily, all I need now is to configure Mesa to use the non-system shipped headers/libraries.

Thanks!

I actually wrote about this very issue in this thread before.

In such case I simply build a newer libdrm package for Debian and install it system wide. It's easier than pointing to some custom libdrm location when building. In your case you need both regular and dev package for building Mesa.

I wrote down for myself how to do it, so here is my note:

Let's say Debian still has older libdrm (let's say 2.4.97), and you want a newer one (2.4.99).

Make sure to have devscripts package installed.

wget https://dri.freedesktop.org/libdrm/libdrm-2.4.99.tar.gz -O $HOME/downloads/libdrm-2.4.99.tar.gz

mkdir -p $HOME/build/libdrm
cd $HOME/build/libdrm
sudo apt-get build-dep libdrm
apt-get source libdrm
cd libdrm-2.4.97
uupdate ~/downloads/libdrm-2.4.99.tar.gz
cd ../libdrm-2.4.99
dpkg-buildpackage -us -uc -nc

# You might need to add some missing symbol definitions along the way to match new upstream

To build 32-bit variant, use:

apt-get build-dep -a i386 libdrm
dpkg-buildpackage -a i386 -us -uc -nc

# You might need to install some gcc packages manually, since apparently build-dep -a i386 is not enough.

# Possibly dpkg --force-overwrite -i is needed, to work around changelog
conflicts in packages.

Thanks for the tips, I went ahead and compiled/packaged the new libs. Installation went smooth and the Mesa config did get to the next step. I still have a few outdated packages to work on but getting there.

Considering how old Debian 9 is, all the signs would tell me to go for something newer. It's been a fun learning experience though so I'll keep digging :)

Sure, upgrade to Debian testing, and avoid the mess. Even there such stuff as above is needed during freeze periods, that's why I was doing it. But for the most part it's up to date.

They did enable bulk moves, but afetr 5.4-rc1 (i.e. 5.4-rc2 has it). I can't test Aco yet, due to it being still quite buggy with Navi.

Maybe it improved a little bit: https://www.phoronix.com/scan.php?page=news_item&px=RADV-Navi-GFX10-ACO-Lands

Not yet. It's still work in progress.
