Sure, I guess. But that does not change the fact that I cannot use cleanup.h magic in this patchset, yet, as the required changes would have to be done in a separate one. Cheers, -Paul

[PATCH v11 0/7] iio: new DMABUF based API v11

by Paul Cercueil

Hi Jonathan, Here's the v11 of my patchset that introduces DMABUF support to IIO. It addresses the few points that were raised in the review of the v10. It also adds Nuno as a co-developer. Changelog: - [3/7]: - Document .lock_queue / .unlock_queue buffer callbacks - Add small comment to explain what the spinlock protects - Use guard(mutex) - [4/7]: - Remove useless field "attach" in struct iio_dma_buffer_block - Document "sg_table" and "fence" fields in struct iio_block_state - [6/7]: - "a IIO buffer" -> "an IIO buffer" - Add variable name in IOCTL calls - [7/7]: New patch, to document the DMA changes Cheers, -Paul Paul Cercueil (7): dmaengine: Add API function dmaengine_prep_peripheral_dma_vec() dmaengine: dma-axi-dmac: Implement device_prep_peripheral_dma_vec iio: core: Add new DMABUF interface infrastructure iio: buffer-dma: Enable support for DMABUFs iio: buffer-dmaengine: Support new DMABUF based userspace API Documentation: iio: Document high-speed DMABUF based API Documentation: dmaengine: Document new dma_vec API Documentation/driver-api/dmaengine/client.rst | 9 + .../driver-api/dmaengine/provider.rst | 10 + Documentation/iio/iio_dmabuf_api.rst | 54 +++ Documentation/iio/index.rst | 1 + drivers/dma/dma-axi-dmac.c | 40 ++ drivers/iio/Kconfig | 1 + drivers/iio/buffer/industrialio-buffer-dma.c | 178 ++++++- .../buffer/industrialio-buffer-dmaengine.c | 62 ++- drivers/iio/industrialio-buffer.c | 457 ++++++++++++++++++ include/linux/dmaengine.h | 33 ++ include/linux/iio/buffer-dma.h | 31 ++ include/linux/iio/buffer_impl.h | 33 ++ include/uapi/linux/iio/buffer.h | 22 + 13 files changed, 911 insertions(+), 20 deletions(-) create mode 100644 Documentation/iio/iio_dmabuf_api.rst -- 2.43.0

Christian was OK to add cleanup.h support to the DMABUF code as long as the examples were updated as well, but those aren't good candidates as they don't free up the resources in all code paths. > > * Will the desire grow for further collateral evolution according to > affected software components? Not sure what you mean by that. Cheers, -Paul

We discussed this after v6 or v7, DRM/DMABUF maintainers were not keen on doing that *just yet*. Cheers, -Paul
