Hi All,
I have problems with the my PCI OpRom device driver on some platforms.
Driver executing successfully on the old DG41TX motherboard, but on the DH67BL
and on the some new HP motherboards driver does not loading from OpRom on the
PCIe card (probably, even entrypoint does not executing).
Boot process not freezing and UEFI Shell from USB pen loading successfully
after platform initialization.
With "loadpcirom" command from UEFI shell my driver executing successfully on
any platforms.
Thanks, Vladimir.
My entrypoint code:
EFI_STATUS EFIAPI PciDriverEntryPoint
( IN EFI_HANDLE ImageHandle, IN EFI_SYSTEM_TABLE *SystemTable )
{
EFI_STATUS Status;
DEBUG ((EFI_D_INFO, "DRIVER ENTRYPOINT\n"));
//
// Install UEFI Driver Model protocol(s).
//
Status = EfiLibInstallDriverBindingComponentName2 ( ImageHandle,
SystemTable,
&gPciDriverBinding,
ImageHandle,
&gPciComponentName,
&gPciComponentName2
);
ASSERT_EFI_ERROR (Status);
//
// Install UEFI DriverSupportedEfiVersion Model protocol(s).
//
Status = gBS->InstallMultipleProtocolInterfaces (
&ImageHandle,
&gEfiDriverSupportedEfiVersionProtocolGuid,
&gPciDriverSupportedEfiVersion, // EFI_2_40_SYSTEM_TABLE_REVISION NULL
);
ASSERT_EFI_ERROR (Status);
return Status;
}
