Revision f492c171a38d77fc13a8998a0721f2da50835224 authored by Christian König on 13 September 2012, 08:33:47 UTC, committed by Alex Deucher on 13 September 2012, 20:17:49 UTC
Only increase the higher 32bits if we really detect a wrap around. v2: instead of increasing the higher 32bits just use the higher 32bits from the last emitted fence. v3: also use last emitted fence value as upper limit. The intention of this patch is to make fences as robust as they where before introducing 64bit fences. This is necessary because on older systems it looks like the fence value gets corrupted on initialization. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=51344 Should also fix: https://bugs.freedesktop.org/show_bug.cgi?id=54129 https://bugs.freedesktop.org/show_bug.cgi?id=54662 https://bugzilla.redhat.com/show_bug.cgi?id=846505 https://bugzilla.redhat.com/show_bug.cgi?id=845639 3.5 needs a separate patch due to changes in the fence code. Will send that out separately. Signed-off-by: Christian König <deathsimple@vodafone.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
