The goal of this patchset is to improve UIO framework and UIO dmem driver to allow cache-coherent DMA accesses from user-space. This patchset is based on two previous patchsets: 1) [PATCH v5 0/6] UIO driver for APM X-Gene QMTM (Refer, http://www.spinics.net/lists/devicetree/msg58244.html) 2) [PATCH 0/4] Fix and extend uio_dmem_genirq (Refer, https://lkml.org/lkml/2016/5/17/141) We have adopted only patch0-3 of patchset1 which was abandoned long time back. We have taken care of last few unaddressed comments on these patches. The patchset2 is quite recent has been adopted entirely. We have taken care review comments on these patches too. This patchset is based on v4.7-rc7 tag and it is available in uio-v2 branch of https://github.com/Broadcom/arm64-linux.git Changes since v1: - Make patch5 as first patch1 and mark it for linux-stable - Check return value of dma_set_coherent_mask() - Get UIO dmem dynamic region details as module parameter instead of getting it from DT node Ankit Jindal (3): uio: code style cleanup uio: Add new UIO_MEM_PHYS_CACHE type for mem regions Documentation: Update documentation for UIO_MEM_PHYS_CACHE and UIO_MEM_DEVICE Anup Patel (2): uio: Add new UIO_MEM_DEVICE type for mem regions uio: Use new memtypes in uio_dmem_genirq Jan Viktorin (3): uio: fix dmem_region_start computation uio: UIO_IRQ_NONE is a valid option for uioinfo->irq uio: bind uio_dmem_genirq via OF Documentation/DocBook/uio-howto.tmpl | 6 +- drivers/uio/uio.c | 32 ++++-- drivers/uio/uio_dmem_genirq.c | 190 +++++++++++++++++++++++++++-------- include/linux/uio_driver.h | 10 +- 4 files changed, 182 insertions(+), 56 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
