Hallo, seit dem Kernel 6.8 und Mesa 24.1 steht unter dem Namen "Intel Xe" ja ein neuer Treiber für diverse Intel-GPUs zur Verfügung.
Aber kann mir jemand sagen ob der Support dafür auch beim Gentoo-Package "media-libs/mesa" angekommen ist? Das ebuild ist für Leute die nicht täglich ein ebuild schreiben leider nicht so einfach zu lesen.

WEnn das ebuild bisher unbekannte treiber nicht einfach deaktivieren kann dann sollte es mit mesa 24.1 standardmäßg aktiv sein.
zu mindestens laut diesem phoronix artikel: https://www.phoronix.com/news/Intel-Xe-KMD-Mesa-24.1-Default

EDIT: Wobei vermutlich es reicht den intel treiber an sich aktiv zu haben

Ich habe es inzwischen einfach mal ausprobiert und ja der Support dafür ist im Mesa von Gentoo drin aber das ganze hat die Bezeichnung experimentell echt verdient.
Das System hat mit diesem Treiber zwar problemlos gestartet und ich konnte mich auch an meiner KDE-Plasma-Wayland-Session erfolgreich anmelden, doch man merkte allein schon an der Bewegung des Mauszeigers sofort das etwas nicht so ist wie es sein sollte. Und beim Versuch im Vivaldi-Browser einen WebGL-Benchmark laufen zu lassen blockierte des Brwoser und der PC-Lüfter heulte auf wie er es noch nie machte, nicht einmal beim kompilieren von grösseren Packages.

Fazit:
Dieser Treiber wird aktuell zurecht als Experimentell eingestuft, mal sehen wie sich das entwickelt.
Spannend ist es auf jeden Fall.

Hier noch ein paar Infos:
Die Grafikkarte:
00:02.0 VGA compatible controller [0300]: Intel Corporation RocketLake-S GT1 [UHD Graphics 750] [8086:4c8a] (rev 04)

Die zu meiner GPU passende modprobe-Konfig um die Nutzung des "xe"-Modul zu forcieren:
options i915 force_probe=!4c8a
options xe force_probe=4c8a

Mein Mesa-Package mit USE-Flags:
media-libs/mesa-24.2.2::gentoo  USE="X d3d9 llvm lm-sensors (opengl) osmesa proprietary-codecs vaapi vdpau vulkan wayland xa zstd -debug -opencl (-selinux) -test -unwind -valgrind -vulkan-overlay" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="sse2" LLVM_SLOT="18 -15 -16 -17" VIDEO_CARDS="intel lavapipe radeon radeonsi virgl zink -d3d12 (-freedreno) (-lima) -nouveau -nvk (-panfrost) -r300 -r600 (-v3d) (-vc4) (-vivante) -vmware"

Die Frage ist, ob deine GPU überhaupt gut von diesem treiber unterstützt wird.
Im code gibt es einen check welcher folgende Meldung ausgibt, wenn die GPU nicht offiziell untersützt wird:
Quote:
"Support for this platform is experimental with Xe KMD, bug reports may be ignored."

Meine integrierte GPU taucht jedenfalls schon mal in der Liste auf die mit "modinfo xe" angezeigt werden kann (siehe unten).
Ein Zeichen dafür das dieser neue Treiber den alten irgendwann ersetzen soll, zumindest bei einigen GPUs. Letzten Endes wird es vermutlich ähnlich laufen wie beim "amdgpu"-Treiber, der war am Anfang auch nur bei den neusten GPUs zu gebrauchen doch diese Zeiten sind zum Glück schon lange vorbei. Inzwischen ist der alte "radeon"-Treiber nur noch bei GPUs nötig die vom neuen nicht unterstützt werden.
