Subject: [PATCH v1 2/7] kselftest/arm64: mte: user_mem: add tests using tag_offset
Date: Tue, 25 Jan 2022 15:09:15 +0000 [thread overview]
Message-ID: <20220125150920.23955-3-joey.gouly@arm.com> (raw)
In-Reply-To: <20220125150920.23955-1-joey.gouly@arm.com>
Add some tests that place the different tag at MT_GRANULE_SIZE to check
that less than a full page can also be read.
