Description spbrothers 2017-10-31 13:10:47 UTC 
While attempting to run OSMesa Gallium llvmpipe and softpipe software rasterizers on PowerPC with Linux Mesa outputs "Mesa 13.0.6 implementation error: Unexpected format PIPE_FORMAT_A8B8G8R8_UNORM in st_new_renderbuffer_fb". 

Same for 13.0.4.
PowerPC works in big-endian mode.
LLVM version is 3.9.1.
Comment 1 Eric Engestrom 2017-10-31 13:28:02 UTC 
Thank you for running tests on PowerPC, we don't have many people with the right hardware to do that :)
big-/little-endian issues unfortunately come up every now and then because of this lack of testing.

That version is quite old; can you upgrade to 17.2 or above and try again?
It's quite possible the issue has already been fixed.
Comment 2 Emil Velikov 2017-10-31 15:28:05 UTC 
As Eric mentioned - Mesa 13.0.x is EOL. We had a number of PPC fixes since then, so I'd encourage you to try 17.2.3/17.2.4 or master.

Thank you for fast responses. I will try newer version.
Comment 4 Ben Crocker 2018-01-22 21:47:09 UTC 
Yes, please try Mesa 17.2.4 or later; Mesa 17.2.x is up to 17.2.8.
OR you could try Mesa 17.3.1 or 17.3.2.

In late 2016 to mid-2017, Roland Scheidegger, Ray Strode, and I solved
a number of problems in the LLVM software pipeline.  Please see

https://bugs.freedesktop.org/show_bug.cgi?id=100613

for our lengthy discussion.

We would like to close this bug as RESOLVED in light of the
successful resolution of 100613.
