Hi
I've encountered a problem after using the patch from SBL (slimboot)
https://github.com/slimbootloader/slimbootloader/pull/809
The SBL supports resource allocation above the 4GB, but it fails on ASSERT
[PciHostBridgeDxe]
/home/andreyv/edk2/edk2/MdeModulePkg/Bus/Pci/PciHostBridgeDxe/PciRootBridgeIo.c(120):
Bridge->Mem.Limit < 0x0000000100000000ULL
The proposed workaround for this is something like in function
AdjustRootBridgeResource() of
UefiPayloadPkg\Library\PciHostBridgeLib\PciHostBridgeSupport.c :
VOID
AdjustRootBridgeResource (
IN PCI_ROOT_BRIDGE_APERTURE *Io,
IN PCI_ROOT_BRIDGE_APERTURE *Mem,
IN PCI_ROOT_BRIDGE_APERTURE *MemAbove4G,
IN PCI_ROOT_BRIDGE_APERTURE *PMem,
IN PCI_ROOT_BRIDGE_APERTURE *PMemAbove4G
)
{
Io->Base = 0x1000;
Io->Limit = 0xEFFF;
Mem ->Base = 0x80000000;
Mem ->Limit = 0xCFFFFFFF;
PMem ->Base = MAX_UINT64;
PMem ->Limit = 0;
MemAbove4G->Base = MAX_UINT64;
MemAbove4G->Limit = 0;
PMemAbove4G->Base = 0x400000000ULL;
PMemAbove4G->Limit = 0x7FFFFFFFFULL;
}
It is working in my board using SBL, but still with a following error
PciHostBridge driver failed to set EFI_MEMORY_UC to MMIO aperture - Out of
Resources.
Can someone help to resolve this issue ?
Andrey
