Are you using SiS based motherboard by any chance?
Following patch should fix this at the cost of some speed...
I just committed the following patch to r300_reg.h:
Thanks. By the way, I confirmed that fglrx sets those bits in 0x180 on the
following cards:
- 0x4E44 (R300)
- 0x4E50 (RV350)
- 0x4A49 (R420)
... i.e. pretty much across the board. However, there are many other
registers that it touches, and I couldn't test how it affects lockups yet.
How very interesting :) I wonder whether this would fix the apparent
tendency of the driver to spend a lot of time in the kernel waiting for
something on rv350..
Or, at least, that's what top says.
+# define R300_MC_MISC__MC_SAME_PAGE_PRIO_SHIFT 24
+# define R300_MC_MISC__MC_GLOBW_INIT_LAT_SHIFT 24
Is the last 24 supposed to be a 28?
+# define R300_MC_MISC__MC_GLOBW_FULL_LAT_SHIFT 0
Is the last 0 supposed to be a 28?
Yes, to both. Sorry for hasty typing I was about to leave when I read
Aapo's e-mail.
Fixed version is in CVS.
