Subject: [PATCH 0/5] HardwareInterrupt2 protocol
Date: Thu, 16 Feb 2017 22:14:26 +0000 [thread overview]
Message-ID: <20170216221431.280072-1-evan.lloyd@arm.com> (raw)
From: Evan Lloyd <evan.lloyd@arm.com>
This v2 series of patches corrects a problem detected on the ARM Juno
platform that is actually generic (at least to ARM GIC platforms).
The HardwareInterrupt protocol had no means of handling characteristics
like Edge/Level triggered and polarity.
A new HardwareInterrupt2 protocol is added, and code changed to utilise
the new capabilities.
The code is available for examination on Github at:
https://github.com/EvanLloyd/tianocore/tree/376_irqtype_v2
Note: Significant defects exist in the (original) Watchdog handling,
and a new patch will follow shortly.
Ard Biesheuvel (3):
EmbeddedPkg: Introduce HardwareInterrupt2 protocol
ArmPkg/ArmGicDxe: Expose HardwareInterrupt2 protocol
ArmPkg/GenericWatchdogDxe: Set Watchdog interrupt type
Evan Lloyd (2):
ArmPkg: Tidy GIC code before changes.
ArmPkg: Tidy up GenericWatchdogDxe.c
