It's neccessary to allocate a Graphics Stolen Memory area to enable GPU-Passthrough for integrated Intel GPUs. Therefore, use a new memory layout with a static Pci32Baseaddress. Old layout: [... , lowmemlimit] RAM [lowmemlimit, 0xE000 0000] PCI Space New layout: [... , lowmemlimit] RAM [lowmemlimit, gsmbase ] Memory hole (may be absent) [gsmbase , 0xC000 0000] GSM (may be absent) [0xC000 0000, 0xE000 0000] PCI Space Reviewed-by: Peter Grehan <grehan@freebsd.org> Acked-by: Rebecca Cran <rebecca@bsdio.com> Signed-off-by: Corvin Köhne <c.koehne@beckhoff.com> Message-Id: <20210705110842.14088-2-c.koehne@beckhoff.com>
