Subject: [PATCH v3 0/2] XEN SWIOTLB dma operations extension
Date: Tue, 31 Jan 2017 20:30:24 +0200 [thread overview]
Message-ID: <1485887426-9016-1-git-send-email-andrii.anisov@gmail.com> (raw)
From: Andrii Anisov <andrii_anisov@epam.com>
Some drivers need additional dma ops to be provided by xen swiotlb. Because
common operations implementation came from x86 world and does not suite ARM
needs we have to provide needed XEN SWIOTLB for ARM callbacks.
dma_mmap patch is a port of an antique and lost patch discussed here:
http://marc.info/?l=xen-devel&m=139695901430667&w=4
Changes in V3:
- dma ops are moved from ARM specific to generic code
- runtime operation verified for arm64 with LK 4.9
- compilation verified for arm, arm64, x86 with the current LK master HEAD
566cf877a1fcb6d6dc0126b076aad062054c2637
Changes in V2:
- patches are rebased and checked for compilation for x86, arm, arm64 with
the current LK master HEAD 83346fbc07d267de777e2597552f785174ad0373
