If you are looking for help with etnaviv (bug fixing, new features, ..) feel free to contact me!

Having fun working with embedded devices? We sometimes do, literally. Come by booth B4.120 at #electronicaFair 2024 to see the Steam Deck in action, play Quake on our Vivante-based handheld or some WebXR games on @WolvicXR! 🎮➕🐺🟰🏆

🚀 New Blog Post: My journey with CI-Tron at @igalia and the path to a better board farm for etnaviv! From integrating the PDU to tackling gfxinfo and boot challenges - this project was full of insights.

All ready for AWE EU @ARealityEvent, come stop by the booth and chat to us about your browser needs and give Wolvic a try.

The fundamentals of the Enhanced Vision Instruction Set (EVIS) are known and integrated into isaspec, but currently, only disassembly is partially functional.

A feature that has been in development for some time is finally here—Multiple Render Targets. This paves the way for necessary emulation work for GL_RGBA32F to enable GLES 3.0 support.

Igalia is such a force across all the major browser engines. I wish more companies realized that fixing a problem or adding a feature to the web could be as simple as hiring Igalia.

This Saturday I'll be presenting “Mesa 3D unveiled: from glDrawArrays(…) to GPU magic” at #LinuxDay2024 in Dornbirn, Austria. Come say hi if you're around! The talk will be in German. #Mesa3D #OpenSource

And so we end a week of intense knowledge exchange! Thanks everyone who attended our talks and visited our booth at #OSSummit EU, #LinuxPlumbers and #LFEuropeMemberSummit. Big thank you to the sponsors and to the @linuxfoundation for making these events possible.👏 #OpenSource

Made some progress with OpenCL Image read support.

I figured out almost all of the missing stuff, but somehow I am reading from the wrong offset in the image. Took me quite some time to figure this out.

Missed the last end-of-week update.

I want to finish image support first, and then it will be time to think about creating a nice and easy-to-review merge request—possibly multiple ones.

It's been a great week so far.

We are proud to be a platinum level sponsor of this year's @gstreamer conference in Montréal!

See you there!

I made great progress this week 🎊

There are still some hacks, missing features, and a lot of cleanups needed. Maybe a bit of refactoring here and there, but...

Having more known bits for the store instruction brings us one step closer to passing more OpenCL piglits.

It's always a great feeling when you can outperform the blob shader compiler with your own.

Igalia’s Georges Stavracas writes about profiling WebKitGTK (a Linux port of Apple’s WebKit) to see how WebKitGTK is doing after being switched from Cairo to Skia, and how he hooked into WebKitGTK's existing tracing mechanisms to make that much easier

Ever wondered what the extended instruction encoding looks like on Vivante GPUs? https://t.co/HRzN5AqS1f
