Summary: Possible correction for r300_pacify's
R300_RB3D_DSTCACHE_CTLSTAT write
Product: Mesa
Version: CVS
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/r300
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
This patch modifies r300_pacify's write to R300_RB3D_DSTCACHE_CTLSTAT to be
more
correct according to Vladimir's comment in r300_reg.h. Apparently we should
write 0xa before 3D operations, and 0x2 afterwards.
I am not entirely sure this is correct, but I tested it with glxgears and it
seems to not cause any regressions. I'm not sure it actually helps anything
other than technical correctness, so it some other people could test it and
make
sure I haven't broken anything, I'd appreciate it.
It is possible that fglrx's behaviour has changed since Vladimir's comment,
too.
