Add 64M@0xDB000000 for GVT-d usage as below. Currently, use 64M for graphics stolen memory, gop driver and uos IGD driver will use this memory region. start end size Note [0x 00000000, 0x 000A0000] 640K [0x 000A0000, 0x 00100000] 384K [0x 00100000, 0x 7ff00000] 2G-1M lowmem-1M [0x 80000000, 0x 88000000] 128M [lowmem, +128M] [0x DB000000, 0x DF000000] 64MB graphics stolen memory for GVT-d [0x DF000000, 0x E0000000] 16M gvt [0x e0000000, 0x100000000] 512M [0x100000000, 0x140000000] 1G Tracked-On: #4360 Signed-off-by: Junming Liu <junming.liu@intel.com> Reviewed-by: Zhao Yakui <yakui.zhao@intel.com> Reviewed-by: Liu XinYun <xinyun.liu@intel.com> Reviewed-by: Shuo A Liu <shuo.a.liu@intel.com> Reviewed-by: Wu Binbin <binbin.wu@intel.com> Acked-by: Yu Wang <yu1.wang@intel.com>
