I never understood the meaning of this bit.
table 4 "_CST FFH GAS Field Encoding"
Bit 1: Set to 1 if OSPM should use Bus Master avoidance for this C-state
Does it mean OS should check BM_STS or does it mean OS OS should do ARB_DIS to
avoid BM activity before entering this C-state?
I always felt that its the second one. But, never saw any BIOS having this bit
set..
