C++ (Cpp) EFI_BOOT_SERVICES::RaiseTPL Examples

Example #1

File: BootServices.c Project: jief666/clover

EFI_TPL EFIAPI
OvrRaiseTPL(IN EFI_TPL NewTpl)
{
	EFI_TPL				Status;
	
	Status = gOrgBS.RaiseTPL(NewTpl);
	// do not print - it's called by UEFI events and timers (from timer interrupts) many times
	//PRINT("->RaiseTPL(NewTpl=%d) = %d\n", NewTpl, Status);
	return Status;
}

Example #2

File: nii.c Project: baloo/ipxe

/**
 * Block callback
 *
 * @v unique_id		NII NIC
 * @v acquire		Acquire lock
 */
static EFIAPI VOID nii_block ( UINT64 unique_id, UINT32 acquire ) {
	struct nii_nic *nii = ( ( void * ) ( intptr_t ) unique_id );
	EFI_BOOT_SERVICES *bs = efi_systab->BootServices;

	/* This functionality (which is copied verbatim from the
	 * SnpDxe implementation of this function) appears to be
	 * totally brain-dead, since it produces no actual blocking
	 * behaviour.
	 */
	if ( acquire ) {
		nii->saved_tpl = bs->RaiseTPL ( TPL_NOTIFY );
	} else {
