Subject: [RFC for-4.8 v2 0/7] xen/arm: Add support for mapping mmio-sram nodes into dom0
Date: Fri, 3 Jun 2016 15:29:05 +0200 [thread overview]
Message-ID: <1464960552-6645-1-git-send-email-edgar.iglesias@gmail.com> (raw)
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
This series adds support for mapping mmio-sram nodes into dom0
as normal uncached MEMORY with RWX perms.
If the no-memory-wc prop is present, we create DEVICE RW mappings.
Patch 6 is a bit of a hack to avoid remapping the mmio-sram
sub-area nodes. These nodes represent allocations within the
sram and not mappings that Xen should create.
Comments welcome!
Best regards,
Edgar
ChangeLog:
v1 -> v2
* Replace the .map method with a list of match -> map attributes
* Handle no-memory-wc by mapping as DEVICE RW
* Generalize map_regions_rw_cache instead of adding new functions
Edgar E. Iglesias (7):
xen/arm: Add MATTR_MEM_NC for normal non-cacheable memory
xen/arm: Rename and generalize un/map_regions_rw_cache
xen/device-tree: Add __DT_MATCH macros without braces
xen/device-tree: Make dt_match_node match props
xen/arm: domain_build: Plumb for different mapping attributes
xen/device-tree: Add an mmio-sram bus
xen/arm: Map mmio-sram nodes as normal un-cached rwx memory
