https://bugs.freedesktop.org/show_bug.cgi?id=32645 --- Comment #29 from Francisco Jerez <currojerez at riseup.net> 2011-01-21 18:49:39 PST --- (In reply to comment #28) > Created an attachment (id=42295) --> (https://bugs.freedesktop.org/attachment.cgi?id=42295) > TVdump from nouveau running 1600x1200 Apparently this video mode is making your card hit its memory bandwidth limits - a 279MHz memory clock (the default your BIOS sets) is usually enough for it, but when you start doing acceleration the CRTC FIFOs get filled more slowly and they eventually underflow, causing this corruption. The last two patches set a more aggressive CRTC FIFO arbitration policy. That doesn't seem to be enough. Does it get any better with "nouveau.perflvl_wr=7777 nouveau.perflvl=0" in the kernel command line? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
