Hopefully Jonathan finds one soon.

Support for LoongArch is now in # next and might be merged into # 5.19: lore.kernel.org/all/CAK8P3a15o…

"LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V" (quoted from the cover letter: lore.kernel.org/all/2022051809… )

Mesa 3d 22.1.0 is out: lists.freedesktop.org/archives/mesa-…

Highlights:

* support for new GPUs from # and #
* WSL now supports OpenGL 4.2
* WSL now supports Vulkan thx to the driver Dozen "dzn"
* as always: general and game/app specific performance improvements and bug-fixes

# # 5.18-rc7, final likely to be released in a week from now: lore.kernel.org/lkml/CAHk-=wg2…

"So things continue to be fairly calm, and as such this is likely the last rc before 5.18 unless something bad happens next week.

Please give it one last week of testing […]"



Would #'s GPUs even had a chance to work well & performant in this bright new CXL server future, if they had continued with a proprietary # # driver? They already ran into roadblocks (lwn.net/Articles/82759… ) and I wonder if CXL would have made things far worse.

PSA: even with Nvidia's open kernel driver a lot of (most?) # # developers will likely continue to ignore bug reports happening when this driver is in use, as out-or-tree code can cause all sorts of issues everywhere in the kernel.
NVIDIA Releases Open-Source GPU Kernel Modules



[bookmark=https://twitter.com/never_released/status/1524482785800601602]My comment on the NVIDIA GPU kernel module:

> The open flavor of kernel modules supports Turing, Ampere, and forward. […] the open kernel modules depend on the GPU System Processor (GSP) first introduced in Turing.
