Li Peng ee980b8003 drm/i915: enable memory self refresh on 9xx ... Enabling memory self refresh (SR) on 9xx needs to set additional register bits. On 945, we need bit 31 of FW_BLC_SELF to enable the write to self refresh bit and bit 16 to enable the write of self refresh watermark. On 915, bit 12 of INSTPM is used to enable SR. SR will take effect when CPU enters C3+ state and its entry/exit should be automatically controlled by H/W, driver only needs to set SR enable bits in wm update. But this isn't safe in my test on 945 because GPU is hung. So this patch explicitly enables SR when GPU is idle, and disables SR when it is busy. In my test on a netbook of 945GSE chipset, it saves about 0.8W idle power.
