Subject: [RESEND PATCH v2 0/3] iommu/arm-smmu: Split pagetable support
Date: Mon, 8 Jul 2019 13:00:44 -0600 [thread overview]
Message-ID: <1562612447-19856-1-git-send-email-jcrouse@codeaurora.org> (raw)
(RESEND because I fat fingered a email address and I didn't want everybody to
get a bunch of SMTP errors)
This series implements split pagetable support for arm-smmu-v2 devices. You have
seen this code before as part of [1] but I split it apart from the other
features to make it easier to review / merge.
This series adds a new format type to io-pgtable-arm to enable TTBR0 and
TTBR1. Because of the way that the registers are mixed up it makes the most
sense to enable them together instead of trying to create two different
pagetables and merge them together later in the arm-smmu drive.
This will be used later by the drm/msm driver to enable split pagetables
as part of the effort to implement per-context pagetables [2].
Thanks,
Jordan
