From ee3db4fc04714c80196e49f8f3a5f157f20d2862 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sat, 24 Mar 2018 18:40:22 +0100 Subject: [PATCH] efi_loader: use TPL_NOTIFY for network timer event We use a timer to poll the network. iPXE is used for booting from iSCSI drives. It has been changed to run at TPL_CALLBACK most of the time (which is not what the UEFI spec recommends). By changing our timer to TPL_NOTIFY we can ensure that it is nevertheless executed.
