12:26 <Hazematman> Hey is there any instructions for running zink with lavapipe? I'm trying to debug this failure but when I run any gl app I get "error: ZINK: failed to choose pdev". I'm setting VK_DRIVER_FILES, LD_LIBRARY_PATH, and MESA_LOADER_DRIVER_OVERRIDE

12:29 <fdobridge> <S​id> zink with lavapipe sure is a unique usecase when llvmpipe exists

12:31 <tintou> Hazematman: are you using LIBGL_ALWAYS_SOFTWARE=true?

12:32 <Hazematman> tintou: No, i'm not. Trying that now and running eglinfo gets me a crash in x11_xlib_display_is_thread_safe

12:34 <tintou> Do you intend to use X11 or is EGL_PLATFORM="surfaceless" enough for you?

12:34 <Hazematman> No I just want to reproduce the issue in CI

12:35 <zmike> LIBGL_ALWAYS_SOFTWARE=true must be set and that's it

12:35 <zmike> assuming the icd is found and such

12:35 <Hazematman> surfaceless doesn't seem to help with eglinfo something else must be messed up

12:36 <Hazematman> zmike: yeah that was all that was needed to get zink to initalize, now its crashing in wsi stuff 🙃

12:36 <zmike> perfect

12:36 <Hazematman> thanks guys!

12:39 <Hazematman> The culprit of one of the crashes https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/vulkan/wsi/wsi_common.c?ref_type=heads#L200 👀

14:58 <fdobridge> <O​wo> It's useful for testing, I'd imagine. Especially if you need to debug and double check if the Vulkan driver is the issue.
