Subject: [RFC PATCH v4 0/6] arm64: tlb: add support for TTL feature
Date: Tue, 24 Mar 2020 21:45:28 +0800 [thread overview]
Message-ID: <20200324134534.1570-1-yezhenyu2@huawei.com> (raw)
In order to reduce the cost of TLB invalidation, the ARMv8.4 TTL
feature allows TLBs to be issued with a level allowing for quicker
invalidation. This series provide support for this feature.
Patch 1 and Patch 2 was provided by Marc on his NV series[1] patches,
which detect the TTL feature and add __tlbi_level interface.
See patches for details, Thanks.
