Since the device addresss has been translated in PciRootBridgeIo.c
so shuldn't translate it twice in ArmPciCpuIo2Dxe.c

The I/O translation in the I/O domain and the mapping of the I/O window in the physical memory space are two different translations, and they both need to be applied. PciRootBridgeIo.c deals with the former, whereas this driver deals with the latter. > --- > ArmPkg/Drivers/ArmPciCpuIo2Dxe/ArmPciCpuIo2Dxe.c | 2 -- > 1 file changed, 2 deletions(-) > > diff --git a/ArmPkg/Drivers/ArmPciCpuIo2Dxe/ArmPciCpuIo2Dxe.c b/ArmPkg/Drivers/ArmPciCpuIo2Dxe/ArmPciCpuIo2Dxe.c > index d8625e1593..8c46a2778b 100644 > --- a/ArmPkg/Drivers/ArmPciCpuIo2Dxe/ArmPciCpuIo2Dxe.c > +++ b/ArmPkg/Drivers/ArmPciCpuIo2Dxe/ArmPciCpuIo2Dxe.c > @@ -399,7 +399,6 @@ CpuIoServiceRead ( > return Status; > } > > - Address += PcdGet64 (PcdPciIoTranslation); > > // > // Select loop based on the width of the transfer > @@ -485,7 +484,6 @@ CpuIoServiceWrite ( > return Status; > } > > - Address += PcdGet64 (PcdPciIoTranslation); > > // > // Select loop based on the width of the transfer > -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
