source: vbox/trunk/src/VBox/VMM/VMMRC/PDMRCDevice.cpp@ 45792

Last change on this file since 45792 was 44902, checked in by vboxsync, 12 years ago

Relevant PDMDevHlpPhysWrite changed to PDMDevHlpPCIPhysWrite. If this breaks anything, add PDM_DO_NOT_RESPECT_PCI_BM_BIT to VMM_COMMON_DEFS to disable the feature.
