Commen= t # 71 on bug 97879<= /a> from Marek Ol=C5=A1=C3=A1k 
The current heuristic in Mesa is that if a buffer is not mappe=
d for read, Mesa
doesn't enable CPU caches for the mapping. It's usually an optimal solution=
 for
write-only buffer uploads.

Enabling CPU caches for mapped buffers adds a lot of inefficiencies, so it
should be avoided.
