Subject: [PATCHv4 0/5] Atomic pool for arm64
Date: Tue, 22 Jul 2014 18:35:03 -0700 [thread overview]
Message-ID: <1406079308-5232-1-git-send-email-lauraa@codeaurora.org> (raw)
Hi,
This is another revision of the series to properly add atomic allocations
for arm64. This version mostly addressed review comments. As always,
reviews and testing welcome
Thanks,
Laura
v4: Addressed comments from Thierry and Catalin. Updated map_vm_area call in
dma_common_pages_remap since the API changed.
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.

common: dma-mapping: Introduce common remapping functions
arm: use genalloc for the atomic pool
arm64: Add atomic pool for non-coherent and CMA allocations.
