Subject: [PATCHv4 0/5] DMA Atomic pool for arm64
Date: Wed, 2 Jul 2014 11:03:33 -0700 [thread overview]
Message-ID: <1404324218-4743-1-git-send-email-lauraa@codeaurora.org> (raw)
Hi,
This is the latest in a series to add support for atomic DMA allocations
for non-coherent/CMA code paths in arm64. I did some refactoring to have
arm also use genalloc and pull out some of the remapping code.
This could probably use more testing on other platforms, especially those
that have CONFIG_ARM_DMA_USE_IOMMU set.
Thanks,
Laura
v4: Simplified the logic in gen_pool_first_fit_order_align which makes the
data argument actually unused.
v3: Now a patch series due to refactoring of arm code. arm and arm64 now both
use genalloc for atomic pool management. genalloc extensions added.
DMA remapping code factored out as well.
v2: Various bug fixes pointed out by David and Ritesh (CMA dependency, swapping
coherent, noncoherent). I'm still not sure how to address the devicetree
suggestion by Will [1][2]. I added the devicetree mailing list this time around
to get more input on this.

Laura Abbott (5):
lib/genalloc.c: Add power aligned algorithm
lib/genalloc.c: Add genpool range check function
common: dma-mapping: Introduce common remapping functions
arm: use genalloc for the atomic pool
arm64: Add atomic pool for non-coherent and CMA allocations.
