Big Improvements For Qualcomm GPU Driver With Linux 6.17 - Especially For Snapdragon X

([Linux Kernel] 3 Hours Ago Qualcomm MSM DRM Driver)


Sent out today by longtime Freedreno/MSM open-source Qualcomm GPU driver developer Robin Clark are the main set of MSM kernel graphics/display driver updates targeting the upcoming Linux 6.17 merge window. There are several exciting feature additions coming to this next kernel version for those relying on Qualcomm graphics capabilities.

First up, the MSM kernel graphics driver is landing VM_BIND support. VM_BIND can help with lowering CPU overhead for the user-space Mesa drivers to deliver better performance. Additionally, VM_BIND is needed for Vulkan sparse requirements. The VM_BIND support for the Qualcomm MSM driver has been in development for a while and amounts to dozens of patches with the main focus on being supporting the Vulkan sparse memory needs by the TURNIP Mesa driver.

Another notable feature addition is providing Qualcomm Adreno X1-85 GPU "speedbin" support. [1]Speedbin is important for reaching the maximum performance capabilities on Snapdragon graphics processors. The Adreno X1-85 is interesting for being the graphics found on the Qualcomm Snapdragon X Elite laptops. Long story short, with Linux 6.17 the graphics performance will hopefully be nicely improved thanks to the speedbin functionality now in place.

This open-source driver code also has Snapdragon X1-45 GPU support for that graphics processor found within the Snapdragon X Plus SoCs.

The MSM driver changes for Linux 6.17 also now provide a single source of truth for Universal Bandwidth Compression (UBWC) configuration handling, further decoupling between the GPU and KMS code, SM8750 support in the DPU and DSI and MDSS code, and various fixes.

More details on these pending Qualcomm MSM DRM driver improvements slated for Linux 6.17 via [2]today's pull request to DRM-Next. I'll be working on some new [3]Qualcomm Snapdragon X Elite benchmarks with the Acer X1E laptop once the Linux 6.17 cycle is underway.

New Linux Companies Hope To Get Rich Quick (#4)

The buzz surrounding Linux and Open Source during 1999 has produced a
large number of billionnaires. However, people who weren't employed by Red
Hat or VA Linux, or who didn't receive The Letter, are still poor. The
visionaries at The IPO Factory want to change all that.

As the name suggests, this company helps other businesses get off the
ground, secure investments from Venture Capitalists, and eventually hold
an IPO that exits the stratosphere. "You can think of us as meta-VCs," the
IPO Factory's founder said. "You provide the idea... and we do the rest.
If your company doesn't hold a successful IPO, you get your money back,
guaranteed!" He added quickly, "Of course, if you do undergo a billion
dollar IPO, we get to keep 25% of your stock."

The company's first customer, LinuxOne, has been a failure. "From now on
we're only going to service clients that actually have a viable product,"
an IPO Factory salesperson admitted. "Oh, and we've learned our lesson:
it's not a good idea to cut-and-paste large sections from Red Hat's S-1
filing."
