When trying to start firefox, I get the following messages: ---8<--- ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. Crash Annotation GraphicsCriticalError: |[0][GFX1]: Unknown image format 0 (t=1.61474) [GFX1]: Unknown image format 0 Exiting due to channel error. Segmentation fault ---8<--- I expect the segfault is intentional and triggered by the handler for critical errors. Anyway, image format 0 is SurfaceFormat::B8G8R8A8, which on little endian is aliased to SurfaceFormat::A8R8G8B8_UINT32 and equivalent to CAIRO_FORMAT_ARGB32, which makes the conversion function at gfx/2d/HelpersCairo.h line 139 work normally: ---8<--- static inline cairo_format_t GfxFormatToCairoFormat(SurfaceFormat format) { switch (format) { case SurfaceFormat::A8R8G8B8_UINT32: return CAIRO_FORMAT_ARGB32; case SurfaceFormat::X8R8G8B8_UINT32: return CAIRO_FORMAT_RGB24; case SurfaceFormat::A8: return CAIRO_FORMAT_A8; case SurfaceFormat::R5G6B5_UINT16: return CAIRO_FORMAT_RGB16_565; default: gfxCriticalError() << "Unknown image format " << (int)format; return CAIRO_FORMAT_ARGB32; } } ---8<--- However, on big endian the CAIRO_FORMAT_ARGB32 and SurfaceFormat::A8R8G8B8_UINT32 formats correspond to SurfaceFormat::A8R8G8B8 (4) instead. This is the format that needs to be used, as SurfaceFormat::B8G8R8A8 would correspond to CAIRO_FORMAT_BGRA32, which does not exist. Cairo requires the alpha bits to be in the MSBs for 32-bit formats. Reproducible: Always Steps to Reproduce: 1.Build firefox 102 on ppc64 (big endian). Note that two patches from https://bugs.gentoo.org/873340 are needed to fix webrtc related build failures. 2.Start firefox 3. Actual Results: A window opens but immediately closes, and the terminal shows a critical error and segfault Expected Results: The firefox window stays open and lets me browse the WWW.

I wonder if this is due to the patches we added, or if we missed something... does either esr or rapid work? I have no clue really, not much to search upstream bugzilla either. If you find patches that help, I can add them to our patch set.
esr (102.3.0) is the one I tested. rapid (105.0.1) has the same issue, and is also affected by bug #873340, although only the first half and not the DesktopCapturer bit.
If it's webrtc related, I wonder if we should just disable webrtc on ppc64? AFAIK it doesn't even have the media sandbox available on ppc64 making webrtc a bit more unsecure on ppc64.
Personally I don't care either way as I don't use webrtc (if it's easy to disable maybe have a use flag for it and everybody who doesn't care about webrtc can just turn it off regardless of arch?). The webrtc patch seems rather straightforward though; the image format regression appears more complex IMO.
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=d52d5a3733acdf481f514dd1e7733d438a33941a commit d52d5a3733acdf481f514dd1e7733d438a33941a Author: Joonas Niilola <juippis@gentoo.org> AuthorDate: 2022-10-18 12:49:49 +0000 Commit: Joonas Niilola <juippis@gentoo.org> CommitDate: 2022-10-18 12:54:47 +0000 www-client/firefox: add 106.0 - add a patch to update bindgen cargo crate, - llvm:15 can't still be enabled due to rust lacking support - it wouldn't work for everyone, - pinned lld dependencies on slots, now that lld is gloriously slotted, - rebased our no-warnings-as-errors patch, - rebased our system-av1 patch, - upstream enabled support for mold linker, but we can't enable it yet (easily) before support is added to toolchain-funcs.eclass. Track the support in bug #877539.
