Subject: intel: Fix aux map alignments on 32-bit builds.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8dc0540a171627cb502f76c75a29a43a86328a95;p=mesa.git

intel: Fix aux map alignments on 32-bit builds.

ALIGN() brilliantly uses uintptr_t, making it unsafe for use with 64-bit
GPU addresses in 32-bit builds of the driver.  Use align64() instead,
which uses uint64_t.

Fixes assertion failures when running any 32-bit program on Tigerlake.

Fixes: 2e6a7ced4db ("iris/gen12: Write GFX_AUX_TABLE base address register")
Fixes: 0d0290bb3f7 ("intel/common: Add surface to aux map translation table support")
