I believe those are Merrifield and Moorefield. gma500 doesn't support them. However 64-bit Cedarview is supported. The register PSB_BSM is the base of stolen memory which is set by BIOS. IIRC the SGX only supports 32-bit addresses so I would be surprised if PSB_BSM would ever be longer than 32-bits. -Patrik > > -- > With Best Regards, > Andy Shevchenko > >
