Subject: [PATCH 4/4] selftest/arm64: Add MTE test config fragment
Date: Thu, 20 Aug 2026 16:33:26 +0100 [thread overview]
Message-ID: <20260820153331.2448875-5-usama.anjum@arm.com> (raw)
In-Reply-To: <20260820153331.2448875-1-usama.anjum@arm.com>
The arm64 selftest collection has no Kconfig fragment, so kernels built
with the selftest requirements are not guaranteed to provide the support
used by the MTE tests.
Add a fragment covering the userspace MTE and tagged-address ABIs, KSM
and its sysfs interface, explicit HugeTLB mappings and their proc/sysctl
interfaces, and tmpfs-backed file mappings.
Do not request NUMA solely for the optional KSM merge_across_nodes.
