Subject: [PATCH v14 00/10] iommu: I/O page faults for SMMUv3
Date: Thu, 1 Apr 2021 17:47:09 +0200 [thread overview]
Message-ID: <20210401154718.307519-1-jean-philippe@linaro.org> (raw)
Add stall support to the SMMUv3 driver, along with a common I/O Page
Fault handler.
Since [v13] I added review and ack tags (Thanks!), and a lockdep_assert.
It would be good to have all of it in v5.13, since patch 10 introduces
the first user for the IOPF interface from patch 6. But if that's not
possible, please pick patches 1-6 so the Vt-d driver can start using
them.
[v13] https://lore.kernel.org/linux-iommu/20210302092644.2553014-1-jean-philippe@linaro.org/
