Re: [Linaro-mm-sig] [virtio-dev] Re: [PATCH v5 0/3] Support virtio cross-device resources
Unless there are any remaining objections to these patches, what are the next steps towards getting these merged? Sorry, I'm not familiar with the workflow for contributing patches to Linux.
Thanks, David

This patchset implements the current proposal for virtio cross-device resource sharing [1]. It will be used to import virtio resources into the virtio-video driver currently under discussion [2]. The patch under consideration to add support in the virtio-video driver is [3]. It uses the APIs from v3 of this series, but the changes to update it are relatively minor.
This patchset adds a new flavor of dma-bufs that supports querying the underlying virtio object UUID, as well as adding support for exporting resources from virtgpu.
Gerd, David, if possible, please test this in configuration with virtual VTD enabled but with iommu_platform=off to make sure we didn't break this config.
Besides that, for virtio parts:

Sorry, just have been busy and not paying as much attention to drm patches as usual. Playing catch-up now. Queued for drm-misc-next, unless something goes wrong in my testing the patches should land in linux-next soon and be merged upstream in the next merge window.
take care, Gerd

Oh, spoke too soon. scripts/checkpatch.pl has a bunch of codestyle warnings. Can you fix them and resend?
thanks, Gerd

Sent a new version to fix the line length warning. There's still a MAINTAINER warning, but I think the new virtio_dma_buf file can fall under virtio core (and the existing wildcards do match it), rather than get its own MAINTAINER entry. I can break it out into its own thing if that's better, though.
