We are currently using 8 bit read cycles. This needs to be wider, at least 32bit reads to reduce the time for oprom shadow Signed-off-by: Sumana Venur <sumana.ve...@intel.com> --- MdeModulePkg/Bus/Pci/PciBusDxe/PciOptionRomSupport.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/MdeModulePkg/Bus/Pci/PciBusDxe/PciOptionRomSupport.c b/MdeModulePkg/Bus/Pci/PciBusDxe/PciOptionRomSupport.c index c994ed5fe3..a981f93f43 100644 --- a/MdeModulePkg/Bus/Pci/PciBusDxe/PciOptionRomSupport.c +++ b/MdeModulePkg/Bus/Pci/PciBusDxe/PciOptionRomSupport.c @@ -521,9 +521,9 @@ LoadOpRomImage ( // PciDevice->PciRootBridgeIo->Mem.Read ( PciDevice->PciRootBridgeIo, - EfiPciWidthUint8, + EfiPciWidthUint32, RomBar, - (UINT32) RomImageSize, + (UINT32) RomImageSize/sizeof(UINT32), Image ); RomInMemory = Image; -- 2.16.2.windows.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
