Mesa 24.03 + etnaviv = Multiple Render Targets (MRTs)!
The latest release of Mesa 24.03 brings exciting news for the etnaviv GPU driver: support for Multiple Render Targets (MRTs)!

christian-gmeiner.info · Multiple Render Targets for etnavivModern graphics programming revolves around achieving high-performance rendering and visually stunning effects. Among OpenGL’s capabilities, Multiple Render Targets (MRTs) are particularly valuable for enabling advanced rendering techniques with greater efficiency.
With the latest release of Mesa 24.03 and the commitment from Igalia, the etnaviv GPU driver now includes support for MRTs. If you’ve ever wondered how MRTs can transform your graphics pipeline or are curious about the challenges of implementing this feature, this blog post is for you.

christian-gmeiner.info · CI-Tron: A Long Road to a Better Board FarmI’m a big supporter of finding problems before they get into the code base. The earlier you catch issues, the easier they are to fix. One of the main tools that helps with this is a Continuous Integration (CI) farm. A CI farm allows you to run extensive tests like deqp or piglit on a merge request or even on a private git branch before any code is merged, which significantly helps catch problems early.
One step closer to getting the etnaviv CI back online.

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.

This blog post is part 1 of a series of blog posts about isaspec and its usage in the etnaviv GPU stack.
I will add here links to the other blog posts, once they are published.
The first time I heard about isaspec, I was blown away by the possibilities it opens. I am really thankful that Igalia made it possible to complete this crucial piece of core infrastructure for the etnaviv GPU stack.
Exciting news on my blog! I’ve written about the latest improvements in the etnaviv GPU stack and how I am integrating a hardware database into Mesa to enhance driver development.
christian-gmeiner.info · hwdb - The only truthTrusting hardware, particularly the registers that describe its functionality, is fundamentally risky.
tl;dr The etnaviv GPU stack is continuously improving and becoming more robust. This time, a hardware database was incorporated into Mesa, utilizing header files provided by the SoC vendors.
If you are interested in the implementation details, I recommend checking out this Mesa MR.
Are you employed at Versilicon and want to help? You could greatly simplify our work by supplying the community with a comprehensive header that includes all the models you offer.
New blog post: The Year 2023 in Retrospect https://christian-gmeiner.info/2022-12-26-end-of-year/
christian-gmeiner.info · The Year 2023 in RetrospectHolidays are here and I have time to look back at 2023. For six months I have been working for Igalia and what should I say?
I ❤️ it!
This was the best decision to leave my comfort zone of a normal 9-5 job. I am so proud to work on open source GPU drivers and I am able to spend much of my work time on etnaviv.
Driver maintenance Before adding any new feature I thought it would be great idea to improve the current state of etnaviv’s gallium driver.
If you're running #phoc's development branch (main, tracking #wlroots git) on a device with split display controller and gpu (like the #librem5 with #etnaviv and mxsfb / dcss) make sure to set
WLR_RENDER_DRM_DEVICE=/dev/dri/renderD128
export WLR_RENDER_DRM_DEVICE
in ~/.phoshdebug as otherwise GTK4 (and lots of other things) will fail to render anything. GTK3 and #phosh itself will work fine.
This doesn't apply when you run nested of e.g. with intel graphics.
Today I looked into OpenCL local memory and under some (yet) unknown conditions the binary blob generates a shader binary that contains a store instructions with a destination register. Yes ... with a destination register ... crazy.
Multiple Render Targets are working - finally. Took me some time to "see" the missing register write in the cmd stream dump.

HW/GPU vendors are very creative when using the available register space. Just pack some values in some unused bits of an already used register and call it a day. Takes some time to RE these things.
