[Mesa-dev] [PATCH] st/mesa: gl_program::info.system_values_read is a 64-bit-field

Michel Dänzer michel at daenzer.net
Thu Mar 8 16:50:01 UTC 2018


From: Michel Dänzer <michel.daenzer at amd.com>

We were dropping the upper 32 bits, which caused assertion failures in
some compute shader piglit tests with radeonsi since the commit below.

Fixes: 752e96970303 ("compiler: Add two new system values for subgroups")
Signed-off-by: Michel Dänzer <michel.daenzer at amd.com>
