Subject: [PATCH v1 0/6] arm64: tlb: add support for TTL feature
Date: Fri, 3 Apr 2020 17:00:42 +0800 [thread overview]
Message-ID: <20200403090048.938-1-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. Patch 3
added __tlbi_user_level interface. Patch 4 was provided by Peter and
added some mmu_gather APIs. Patch 5 provided flush_*_tlb_range wrappers
so we can do the tlb invalidation according to the information in
struct mmu_gather. Finally, we supported TTL feature in ARM64 by using
tlb->cleared_* in struct mmu_gather.
See patches for details, Thanks.
