Intel Drivers With Mesa 26.2 Ready With Xe In Linux 7.1 To Better Handle vRAM Pressure

([Intel] 3 Hours Ago Out Of Memory Behaviro)


Merged to the Intel Xe kernel graphics driver with Linux 7.1 is an addition to [1]improve the video RAM memory pressure or out-of-memory behavior for Intel graphics with dedicated video memory. Introduced is support for purgeable buffer objects via a new user-space API to provide usage hints for enhancing what is purged under vRAM pressure. Merged this week to Mesa 26.2-devel is support for the Intel Mesa drivers to make use of this new interface.

The Intel driver code in Mesa 26.2 for the Iris Gallium3D driver and ANV Vulkan driver now support the madvise purgeable VMAs in the Xe kernel driver. This allows the kernel driver to remove the backing storage of VMAs not needed when under memory pressure.

[2]This merge is where the user-space magic happens for supporting the functionality with the Mesa drivers. So look for the Mesa 26.2 and Linux 7.1 combination this summer for enhancing the experience when Intel graphics are running out of video memory / out-of-memory "OOM" behavior.

Meantime, in the slums below Ronnie's Ranch, Cynthia feels as if some one
has made voodoo boxen of her and her favorite backplanes. On this fine
moonlit night, some horrible persona has been jabbing away at, dragging
magnets over, and surging these voodoo boxen. Fortunately, they seem to
have gotten a bit bored and fallen asleep, for it looks like Cynthia may
get to go home. However, she has made note to quickly put together a totem
of sweaty, sordid static straps, random bits of wire, flecks of once meaningful
oxide, bus grant cards, gummy worms, and some bits of old pdp backplane to
hang above the machine room. This totem must be blessed by the old and wise
venerable god of unibus at once, before the idolatization of vme, q and pc
bus drive him to bitter revenge. Alas, if this fails, and the voodoo boxen
aren't destroyed, there may be more than worms in the apple. Next, the
arrival of voodoo optico transmitigational magneto killer paramecium, capable
of teleporting from cable to cable, screen to screen, ear to ear and hoof
to mouth...
