Andrew,
As part of the loop of opening Block_Io devices I put in:
SAFE_OPEN_PROTOCOL_LIB_HANDLE *namehandle;
EFI_COMPONENT_NAME2_PROTOCOL *name;
if ((namehandle=SafeOpenProtocol(handlepointer[i],
&gEfiComponentName2ProtocolGuid, (void**)&name, NULL))!=NULL) {
CHAR16 *drivername;
name->GetDriverName(name, "en-us", &drivername);
CHAR16 *controllername;
name->GetControllerName(name, handlepointer[i], NULL, "en-us",
&controllername);
printf("driver:%ws controller:%ws\n", drivername, controllername);
SafeCloseProtocol(namehandle);
}
else printf("no name protocol\n");
and all that prints is "no name protocol" for all block devices.
Note that the "SafeOpenProtocol" in this case is just emulated, it's
actually opening BY_HANDLE_PROTOCOL. I left that method in there if the
hang issues is ever fixed/figured out.
