In order to comply with a spec requirement, I need to determine how much shared system memory Linux Xorg will allocate to a GS45 GMA X4500 MHD?
[ 0.420285] agpgart-intel 0000:00:00.0: Intel GM45 Chipset
[ 0.422401] agpgart-intel 0000:00:00.0: detected 32764K stolen memory
[ 0.445812] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000
(==) intel(0): VideoRam: 262144 KB
BIOS setting is for "Max DVMT"
System memory, 4G (although BIOS has MAX TOLUD of 3GB). /proc/meminfo MemTotal: 2955604 kB
It's my understanding that Xorg will magically detect a video memory size, but this seems to be 256MB. I'd very much like to be able to control or say with that additional shared memory is used (looking to get 512MB or more). How can I determine/verify additional memory used?
