01:01 <CatSwarm> [context for quote] ~ supposedly, zink [via gallium] works on modern iGPU on modern intel CPUs? / I'm on tigerlake with the decent ~ [by iGPU standards] ~ "iris Xe", which is actually nicer than my old sandybridge era laptop which had a discrete nVidia GPU in it.

01:03 <CatSwarm> basically, I can't seem to figure out how to compile mesa with an iris_dri.so, and I think zink via gallium is probably "good enough" [tm] ~ sanity check if anyone doesn't mind. I'm doing some os devops and porting for previously unsupported hardware with an iris Xe iGPU

01:03 <zmike> set MESA_LOADER_DRIVER_OVERRIDE=zink

01:03 <CatSwarm> I didn't compile with zink

01:03 <CatSwarm> as I said, this is for porting

01:04 <zmike> meson configure -Dgallium-drivers=iris,zink

01:04 <CatSwarm> basically, if you think zink will probably work for the above-described config, that's what I'm thinking and if you're saying it sounds right, and you're not guessing it's appreciated.

01:04 <zmike> I have no idea

01:04 <zmike> probably it would

01:04 <zmike> I don't know why iris wouldn't work though

01:04 <CatSwarm> ah, well. I'm basically doing LFS [linux from scratch] for this distro.

01:05 <CatSwarm> [re: iris] ~ yeah well /usr/lib64/dri/iris_dri.so doesn't exist O_O

01:06 <CatSwarm> either way, I'm going to be trying with zink because the research I've done for other OS devs and porting teams had a loose consensus about zink support being "good enough" [tm] for this hardware.

01:06 <zmike> possibly installed to different prefix

01:06 <CatSwarm> zink definitely beats llvmpipe, which is my current awful hack.

01:06 <zmike> good luck I guess

01:07 <CatSwarm> thanks. if anyone knows for certain ~ [per above question] ~ that'd be appreciated, but I'm intending to throw a new build instructions at my toolchain and give it a best attempt with zink instead of llvmpipe =^.^=

06:19 <CatSwarm> [context] >>> Intel(R) Xe Graphics (TGL GT2)

06:20 <CatSwarm> very close match to what I'm running, validated against mesa 22.1.4

06:26 <CatSwarm> also, I'm pretty sure nobody here caused the issue(s) I'm experiencing, and it's the wrapper which is calling meson not an issue with zink itself ~ [portage, with portage-style configuration knobs] ~ https://github.com/gentoo/gentoo/pull/14605

07:22 <CatSwarm> https://gist.github.com/kuzetsa/ccf37a4276cd505b3ae09ac2991e6e44

07:24 <CatSwarm> ~ it was bad enough that I had to modify the meson wrapper to include iris support because neither crocus nor iris drivers were included, with the default assumption that llvmpipe is better? I guess? either way, I hope this got me sorted O_O

07:26 <CatSwarm> time to fix x11-libs/libdrm while I'm at it because of how mesa / gallium / drm / zink works, I think?

07:39 <CatSwarm> ../libdrm-2.4.112/meson.build:21:0: ERROR: Unknown options: "iris"

07:39 <CatSwarm> I'm stumped

07:40 <CatSwarm> albiet, the naive decision to assume I could just do >>>>> [21:04:26] <zmike> meson configure -Dgallium-drivers=iris,zink

07:44 <CatSwarm> I have no idea how that archlinux user got their iGPU to build vulkan support properly for UHD Graphics 620, so I might end up needing to copy whatever was validated @ https://vulkan.gpuinfo.org/displayreport.php?id=16051

07:48 <CatSwarm> I'm even more stumped than I first thought. I'll just stop guessing and spamming I guess & possibly see if any archlinux users or devs know how they fixed it on that toolchain / source-based distro. blarg.
