I've written a design document for a new input/output linker to replace nir_link_opt_varyings and nir_compact_varyings, but I guess I'll keep it to myself for now

Could someone with the appropriate permissions update the labels on my MR (https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21654#note_1803757). Based on the feedback I added support for get_screen_fd to all the gallium drivers that are missing it, but the MR is only labeled for gallium right now

<jadahl>
when doing eglGetProcAddress() on libEGL from libglvnd, do the function pointer I get point directly into the vendor EGL implementation? if so, how do I affect what vendor's version I get?
<emersion>
i don't think it does
<jadahl>
looking at a backtrace it looks like it
<emersion>
libglvnd does the dispatching to the backend EGL impl I think
<jenatali>
You could just be seeing a tail call optimization?
<emersion>
libglvnd may be doing some magic here, i wouldn't trust a stack trace
<jadahl>
if I load eglInitialize() it'll go directly into libEGL_mesa, if I break on eglInitialize on a path that doesn't use eglGetProcAddress it'll stop in libEGL.so
<emersion>
but it'
<emersion>
s supposed to be usable with multiple EGL backends
<emersion>
so if i have two EGLSurfaces, one from backend A, another from backend B
<emersion>
when i call eglSwapBuffers, depending on the EGLSurface, glvnd needs to dispatch to the correct backend
<emersion>
afaiu
<jadahl>
hrm, I'm let me write a tiny test case and inspect what address space the pointer leads to

eric_engestrom: what about the meson-test section. tbh I would like to have only one uncollapsed section per job; what do you think?
<DavidHeidelberg[m]>
This change MAY prolong discovering of fails. When the job fails, now it'll try twice to run it before it reports failure. This is unlucky. But still better than having to watch Marge-bot dying cause some rare flake.
konstantin has quit [Ping timeout: 480 seconds]
<DavidHeidelberg[m]>
One thing I'm still considering is specifying retry: 1, because 2 seems to be too excessive. On other hand I cannot define retry: 2 for runner_system_failure which would make sense to keep that way.
ybogdano has joined #dri-devel
<DavidHeidelberg[m]>
zmike: would you be still R-b with retry: 1? I think 2 would take too long on failing job
<zmike>
yeah 1 retry is enough to cover all my babysitting

hey, is it possible to use Mesa's Vulkan without the standard overlays?
<mi6x3m>
I get a segfault for CreateCommandPool in vkcube if I don't load any layers
<mi6x3m>
supposedly because vk_device_dispatch_table_load is never called which seems to be the task of the overlay layer

you shouldn't need layers for (most?) Mesa Vulkan drivers
ybogdano has quit [Ping timeout: 480 seconds]
<mi6x3m>
well that's weird because a getprocaddress for CreateControlPool returns NULL
<mi6x3m>
and the only place vk_device_dispatch_table_load is called is in the overlay-layer
<Sachiel>
no, it's not. It's called from the generated entry points code

ah, my bad, you said that one first

yeah, that one should always be there

:) by vk_device_dispatch_table_get_if_supported seems to return an index, 72, but table[72] is then NULL :/

what driver?
