01:03 zzoon: Lynne: Looking into av1 dec on anv now..
01:04 zzoon: found some issues on handling cdf bufs
01:41 Lynne: glehmann: my issue is that I'm several function calls in, most very hot, and checking for the return of every single one of them adds branches in a part where I don't really want branches
04:31 DemiMarie: Lynne: patch Mesa to add the support :P
04:32 Lynne: can't be fixed, its a glsl issue, and as we all know, glsl issues never get fixed
04:33 Lynne: pretty sure there's nothing illegal about outputting spirv OpKill from compute shaders
04:39 Lynne: I'd write in spirv asm if I could, if only spirv assemblers weren't part of the same trainwreck that glsl compilers are, and the IR in spirv was less IR-y and took a book from x86
04:40 HdkR: Time to implement VK_EXT_ARB_shader
04:41 DemiMarie: Why GLSL and not HLSL?
04:42 DemiMarie: Or if this is Mesa-specific just patch Mesa to add a compiler intrinsic.
04:42 Lynne: all roads lead to rome, in other words, anything that touches spirv (except mesa) uses the same piece of cursed libs
04:42 airlied: opkill isn't legal in compute I don't htink
04:43 airlied: I think you just return from the function
04:43 DemiMarie: Can GPUs implement longjmp?
04:43 airlied: at least for kernels
04:44 DemiMarie: Lynne: what is this for?
04:44 Lynne: video decoder running on vulkan
04:45 DemiMarie: Interesting! Is this for when the HW does not support decoding in fixed function?
04:46 Lynne: you can read junk or eos during entropy decoding so rather than overreading, you just want to terminate the invocation immediately
04:46 Lynne: no, its for codecs with no fixed function implementations
04:46 DemiMarie: Interesting! I thought that decompression was too serial to be fast on GPUs.
04:47 Lynne: codecs where the entropy coding state gets reset between blocks can be parallelized
04:47 DemiMarie: Which ones are those?
04:48 Lynne: prores, vc-2, mjpeg, ffv1, many
04:48 Lynne: gopro's old intra codec too
04:48 DemiMarie: Darn it! I was hoping to see the big ones on the list.
04:49 HdkR: ProRes might be a big one in certain circles
04:52 Lynne: prores isn't big enough for you?
04:52 Lynne: 99% of what you see has been prores at some point
04:53 Lynne: though I'm currently writing ffv1, which is what most archival libraries use
04:54 DemiMarie: I don't work in the video production space.
04:55 DemiMarie: I trust that you are right about ProRes being a big deal, but it doesn't come up in my line of work.
04:55 DemiMarie: Or if it does, I'm not aware of it.
04:57 DemiMarie: What got me excited was the possibility of not needing to expose the fixed-function HW blocks and the corresponding attack surface.
05:54 zzoon: Lynne: could u recommend a branch of FFMpeg for testing vk av1 decoding?
05:54 Lynne: git master will work fine
05:55 zzoon: ok
06:38 mareko: eric_engestrom: how do I add -Wno-inconsistent-missing-override to debian-android?
06:42 mareko: eric_engestrom: it ignores options in meson.build
08:48 mareko: jenatali: hi, any idea why this is failing? Assertion failed: var->data.location_frac == 0 && old_length <= 4 - https://gitlab.freedesktop.org/mesa/mesa/-/jobs/68427130
09:04 lorenzoperocci: It was never about who is legit or superior (mistakes is where people get closer to truth but timing is bit different not because of priorities only, but also happenings in life that gets you relaxed, you see i control that without bullying later on in my career, you do not find truth normally but let the truth to find you, and to get there temper needs to be lowered and reactions need
09:04 lorenzoperocci: to go to more dormant or silent versions), it's about the nasty devil opinions and things you do to force others into constrainted situations, in other words deliberate abuse done to certain stereotypes envied, and it was never like i cared as to what your opinions were either, you come to my hotel to harass people for 15 years in a row claiming you are someone but are presenting
09:04 lorenzoperocci: yourself someone who you are not which is where combined with all other abuse lameness already is way too much to handle without trying to using force as last resort. Altogether the truth found me , i am not sure who's heroics it was either, you as behaving idiotically or my temper controlling or the mixture of those, but generally i was dropped into hole where i realized it's so deep
09:04 lorenzoperocci: that i can not get out of there, and best thing to do is to settle down and truth started to find me from my previous attempts with very high percentages, i got more correct results in testing and backed up my theories etc etc. in other words, were able to find proof as evidence or theorems lemmas of my previous temperamented hypothesis, which i never got close being angry or storing
09:04 lorenzoperocci: hatrism. And i have learned not to circulate anger/envy in my daily thoughts otherwise i can not work, it is as simple as that. So you see trends that i flush your opinion , though i know your opinions that i am mentally ill, it never disturbs me if you or me are classified as mentally ill, and all your crap i flush i forgive and forget both tbh. to be able to work better, there is
09:04 lorenzoperocci: some concious parts where i control keeping to memory of your nasty opinions and terror, i just do not call it out daily to be able to work as needed in life until it ends.
10:36 soreau: ping on https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32535
10:37 soreau: daniels: have you had a chance to take a look? ^^
13:16 jenatali: mareko: thanks for the ping, I'll take a look
14:43 daniels: karolherbst: :( :( :( https://gitlab.freedesktop.org/daniels/mesa/-/jobs/68444277#L4591
14:44 karolherbst: daniels: ohh right.. I should fix that, there was an issue already. Let me get it done aspa
14:45 daniels: karolherbst: <3 <3 <3
15:18 karolherbst: daniels: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32723
15:18 daniels: thankyou!
15:19 karolherbst: uhh.. hopefully that still compiles wiht 1.78 🙃 but yeah
15:19 karolherbst: though we might not want to compile with `-D warning` in CI
15:19 karolherbst: not sure what's adding that
15:20 karolherbst: we also don't fail on warnings in C code there
15:21 karolherbst: but maybe it's fine :)
15:24 daniels: passing --werror to Meson does that
15:25 daniels: and there's no way to enable it only for C but not Rust, so if we don't do it then Mesa just becomes a sea of warnings instead :\
15:39 phasta: sima, hi… FYI, I today messed up by applying a patch twice, once to dri-misc-next and dri-misc-fixes. "drm/sched: Fix drm_sched_fini() docu generation" – content is the same, so shouldn't cause a merge conflict, but definitely not good… Mea culpa. Will be very careful in the future
15:41 sima: phasta, ping drm misc maintainers as heads up, so tzimmermann, mlankhorst and mripard
15:42 sima: phasta, also for intentional cherry-picking (e.g. pushed to -next, later on realized it's a bugfix) there's dim cherry-pick
15:42 phasta: ping via mail?
15:42 sima: nah here is good enough
15:42 sima: otherwise no worries, it's not a disaster
15:43 phasta: for me it's the cherry on the icing of a horrible week ^^'
15:43 phasta: thx, will look into dim cherry-pick for next time
15:43 sima: phasta, if you've pushed to -fixes first I would have not bothered with also -next, if that's where you wanted it
15:43 phasta: no, was to -next first
15:43 sima: but if it's accidentally to -next instead of -fixes, pls ask drm-misc maintainers first, they would have told you about dim cherry-pick
15:43 MrCooper: daniels: could pass -Werror via c{,pp}_args ?
15:44 sima: phasta, yeah in general just ask here instead of trying to rectify it yourself, we generally have a process/docs for almost every possible screw-up :-)
15:44 phasta: sima, ACK, thx
15:46 daniels: MrCooper: meh tbh
15:55 mripard: sima: I think we said that cherry-picks were maintainer-only operations though, so we probably shouldn't advertise it :)
15:56 sima: mripard, yeah that's why I told phasta to ping drm-misc maintainers first and not try to rectify themselves
15:56 sima: because if you just cherry-pick no one remembers to check whether dim has a command for that
17:33 mlankhorst: Ohh I got pinged, reminds me to pull request today. :)
18:17 mlankhorst: sima: shouldn't be a big problem to have it applied twice for once though?
18:20 sima: mlankhorst, yeah it's no big deal
20:56 karolherbst: daniels: yeah.. it looks like we simply disable specific warnings causing errors on the C/C++ side then... oh well
21:04 karolherbst: daniels: anyway, if you verify that my MR fixes those build issues I can merge it, though I might just assign to marge right away 🙃 It's not like anything there can break anything
21:04 karolherbst: just would be good to know if there is more or if it's everything
22:05 dcbaker: daniels, karolherbst: We could change `--werror` to accept languages...
