Windows 2008 R2 (which requires a CSM build) doesn't offer me the Suspend option in the Start menu. Not sure why, S3 is advertised and enabled in DSDT/SSDT. In Windows 2012 R2 I tried the "psshutdown -d" command (from <http://technet.microsoft.com/en-us/sysinternals/bb897541.aspx>), but it says "The local system does not support suspend.". I also checked those... ugh... "elements" of the GUI where the suspend option should be offered -- it's not there. I've learned about the "powercfg /a" command. It says: The following sleep states are not available on this system: [...] Standby (S3) An internal system component has disabled this standby state. Graphics [...] (This is distinct from "The system firmware does not support this standby state", so the ACPI tables are probably OK.) The Windows 2012 R2 GUI seems to use the GOP exclusively (which is OK I guess), but for some reason it's exactly the basic GOP driver that prevents S3. ... From googling it seems that I should install a graphics driver that supports suspend/resume explicitly (this does make sense). Alas I know of no such driver. I don't expect one to exist for Cirrus or stdvga. None appear to exist for QXL either: <https://bugzilla.redhat.com/show_bug.cgi?id=957827#c3>. Maybe I could find guest drivers for VMVGA (not sure if those are publicly available), but then we wouldn't have a GOP in OVMF (no support in QemuVideoDxe I think).
