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. > =================================================================== > RCS file: /cvsroot/r300/r300_driver/r300/r300_reg.h,v > retrieving revision 1.41 > diff -u -r1.41 r300_reg.h > --- r300_reg.h 8 Jun 2005 15:05:24 -0000 1.41 > +++ r300_reg.h 10 Jun 2005 16:09:22 -0000 > @@ -1,6 +1,27 @@ > #ifndef _R300_REG_H > #define _R300_REG_H > > +#define R300_MC_INIT_MISC_LAT_TIMER 0x180 > +# define R300_MC_MISC__MC_CPR_INIT_LAT_SHIFT 0 > +# define R300_MC_MISC__MC_VF_INIT_LAT_SHIFT 4 > +# define R300_MC_MISC__MC_DISP0R_INIT_LAT_SHIFT 8 > +# define R300_MC_MISC__MC_DISP1R_INIT_LAT_SHIFT 12 > +# define R300_MC_MISC__MC_FIXED_INIT_LAT_SHIFT 16 > +# define R300_MC_MISC__MC_E2R_INIT_LAT_SHIFT 20 > +# 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_INIT_GFX_LAT_TIMER 0x154 > +# define R300_MC_MISC__MC_G3D0R_INIT_LAT_SHIFT 0 > +# define R300_MC_MISC__MC_G3D1R_INIT_LAT_SHIFT 4 > +# define R300_MC_MISC__MC_G3D2R_INIT_LAT_SHIFT 8 > +# define R300_MC_MISC__MC_G3D3R_INIT_LAT_SHIFT 12 > +# define R300_MC_MISC__MC_TX0R_INIT_LAT_SHIFT 16 > +# define R300_MC_MISC__MC_TX1R_INIT_LAT_SHIFT 20 > +# define R300_MC_MISC__MC_GLOBR_INIT_LAT_SHIFT 24 > +# define R300_MC_MISC__MC_GLOBW_FULL_LAT_SHIFT 0 Is the last 0 supposed to be a 28? cu, Nicolai
