Intel Drivers With Mesa 26.2 Ready With Xe In Linux 7.1 To Better Handle vRAM Pressure
Merged to the Intel Xe kernel graphics driver with Linux 7.1 is an addition to 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.
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.
