From: Philippe Mathieu-Daudé Date: Thu, 12 Oct 2023 11:09:45 +0000 (+0200) Subject: hw/pci-host/designware: Add 'host_mem' variable for clarity X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=50e4291d62970adaa1668aeb4e7dbc7c67739504;p=qemu-xen.git hw/pci-host/designware: Add 'host_mem' variable for clarity designware_pcie_root_realize() uses get_system_memory() as the "host side memory region", as opposed to the "PCI side" one. Introduce the 'host_mem' variable for clarity.
