前面写了一个hello world驱动，现在简单调用一下

-----------------testlib.c文件----------------------------

#include <uefi.h>
#include <library/uefilib.h>
#include <library/basememorylib.h>
#include <library/uefiapplicationentrypoint.h>
#include <Library/UefiBootServicesTableLib.h>
#include <Library/UefiRuntimeServicesTableLib.h>
//#include <protocol/firstdriver.h>
#include <firstdriver/firstdriver.h>

EFI_STATUS EFIAPI UefiMain(IN EFI_HANDLE ImageHandle, IN EFI_SYSTEM_TABLE *SystemTable)
{
EFI_STATUS Status = EFI_SUCCESS;

EFI_FIRSTDRIVER_PROTOCOL *gf;

Status = gBS->LocateProtocol(
  &gEfifirstdriverProtocolGuid,
  NULL,
  &gf
  );

if(EFI_SUCCESS == Status)
{
Print(L"success to locate protocol\n");
}
else
{
Print(L"failed to locate protocvol\n");
}

gf->Func1(gf);
Print(L"ia in protocol is %d\n",gf->ia);

return Status;
}

testlib.dsc的 [libraryclass] 块中加上

firstdriver|firstdriver/firstdriver/firstdriver.inf

-------------------testlib.inf-------------------------

[Packages]
MdePkg/MdePkg.dec
firstdriver/firstdriver.dec

[LibraryClasses]
UefiApplicationEntryPoint
UefiLib

[Protocols]
