Out of memory: Killed process 1820693 (rustc)
With only 4 GB of memory, you need to be careful when building Mesa.

New blog post: PanVK Extension Sprint - Mesa 26.1 🚀
18 Vulkan extensions landed in PanVK for Mesa 26.1 - the open-source Vulkan driver for Arm Mali GPUs. Covering the Proton stack essentials (DXVK, vkd3d-proton), DDK feature parity, and closing gaps on mesamatrix.
From VK_EXT_conditional_rendering to VK_EXT_nested_command_buffer - each one pulls PanVK closer to "throw a DXVK game at it and it just works."
depth32f emulation MR is ready!
Took me some rounds to cleanup and simplify some details, but this is the next big puzzle peace for gles3.

One thing I find hard when working on multiple topics/MRs in parallel is remembering all the details behind why I implemented something a certain way. By the time the first code review arrives - often days/weeks later - I've already moved on mentally and started working on something else.
From time to time I work on kernel stuff, and I finally switched to using b4. It has eliminated so much manual work that I wish I'd made the switch sooner.
To pass more deqp gles3 tests, we need to support UNIFIED_SAMPLER feature of Vivante GPUs. It allows the fragment and vertex stages share one 32-entry
sampler HW array, that gets managed dynamically. With out it there is a fixed 16/16 split.

@karolherbst@chaos.social I'm surprised - yes .. ebc_nir_lower_pack_64.c

@Luigi311@mastodon.social ATM it's still gles2 but I am working actively on it and a lot of gles3/3.1 features are already in place. Using a more recent version gives new working features (even if they are hidden behind an env var) and from time even performance optimizations.
Life is hard - 100 meters away there’s 1 Gbps fiber available… but here? Nothing 😞

@linmob@linuxmobile.social @Luigi311@mastodon.social correct - I work on other areas in mesa too :)

@Luigi311@mastodon.social always try to use a recent/latest mesa version... there is always something for etnaviv.

Spend the nights during the weekend with some time consuming debug of RA issues - looks like it seems to be okay now.

@karolherbst@chaos.social best commit message so far: "hacks.. again .." 😅

@karolherbst@chaos.social I’ll remember this tip for the next feature branch. I actually started catching up with upstream about six months ago. I’m now at a point where I think everything works as expected, but there’s still a lot of cleanup left to do.
The biggest pain point is that about 4–5 months ago, I decided to slowly change the core architecture. I probably should have started fresh back then… but yeah, I didn’t have anything better to do at night.

@Luigi311@mastodon.social I couldn't resist and went with the maxed-out IMX8M version 🙃

@linuxplumbersconf I think the correct link would be https://lpc.events/event/18/abstracts/
