Subject: [PATCH 05/12] OvmfPkg/VirtioSerialDxe: use TPL_NOTIFY

RH-MergeRequest: 39: ArmVirt: add VirtioSerialDxe to ArmVirtQemu builds

RH-Commit: [5/6] 08998538804a8d62903e44e716bcafd9674d208f (kraxel/centos-edk2)
|
||
|
|
|
||
|
|
Apparently TPL_CALLBACK is too low, code runs into an ASSERT
|
||
|
|
complaining the new TPL is lower than the old TPL.
