Hi Andriy,
excellent! This made me add the long overdue register descriptions for the PMBASE area to the patch, which I can use very well for the project I'm working on.
Attached is a new patch that should solve the issues the right way.
Andriy Gapon wrote:
From publicly available ICH9 spec (I guess ICH8 is the same here):
<quote> LV2 — Level 2 Register I/O Address: PMBASE + 14h ... Reads to this register return all 0s, writes to this register have no effect. Reads to this register generate a “enter a level 2 power state” (C2) to the clock control logic. This will cause the STPCLK# signal to go active, and stay active until a break event occurs. Throttling (due either to THTL_EN or FORCE_THTL) will be ignored. ... NOTE: This register should not be used by IA-64 processors or systems with more than 1 logical processor, unless appropriate semaphoring software has been put in place to ensure that all threads/processors are ready for the C2 state when the read to this register occurs. </quote>
The subsequent byte registers are LV3, LV4, LV5 and for mobile version LV6 intended for entering C3, C4, C5 and C6 states.
