Hi guys,
I'm ccining coreboot ml. I still struggle with the flicker during LDTSTOP
transitions on 785G (PCI ID 0x9710 of uma and NB same as RS880). I suspect that
I need to setup something in graphics engine. I checked all possible settings in
NB/SB so I guess it must be something which is set in gfx.c
<------>/* Force allow LDT_STOP Cool'n'Quiet workaround. */
<------>*(GpuF0MMReg + 0x655c/4) |= 1<<4;
I think those bits are read only on my system. Maybe it is something else.
Any idea what to do with that? It seems it needs access to some more advanced
documentation.
Thanks
Rudolf
