Subject: [PATCH v10 18/25] arm64: gic-v3: Implement arch support for priority masking
Date: Thu, 31 Jan 2019 14:58:56 +0000 [thread overview]
Message-ID: <1548946743-38979-19-git-send-email-julien.thierry@arm.com> (raw)
In-Reply-To: <1548946743-38979-1-git-send-email-julien.thierry@arm.com>
Implement architecture specific primitive allowing the GICv3 driver to
use priorities to mask interrupts.
