[PATCH] drm/virtio: Fix an IS_ERR() vs NULL check in virtio_gpu_object_shmem_init()
by Dan Carpenter 19 Jun '20

The drm_gem_shmem_get_pages_sgt() function returns error pointers on error, it never returns NULL.

Hi, my test box won't boot 5.8-rc1 all the way but stops at ... fb0: switching to nouveaufb from EFI VGA <-- EOF I've bisected it to the commit in $Subject, see below. Unfortunately, it doesn't revert cleanly so I can't really do the final test of reverting it ontop of 5.8-rc1 to confirm that this one is really causing it. Any ideas?

[PATCH v6 00/36] DRM: fix struct sg_table nents vs. orig_nents misuse
by Marek Szyprowski 19 Jun '20

19 Jun '20

Dear All, During the Exynos DRM GEM rework and fixing the issues in the. drm_prime_sg_to_page_addr_arrays() function [1] I've noticed that most drivers in DRM framework incorrectly use nents and orig_nents entries of the struct sg_table. In case of the most DMA-mapping implementations exchanging those two entries or using nents for all loops on the scatterlist is harmless, because they both have the same value. There exists however a DMA-mapping implementations, for which such incorrect usage breaks things. The nents returned by dma_map_sg() might be lower than the nents passed as its parameter and this is perfectly fine. DMA framework or IOMMU is allowed to join consecutive chunks while mapping if such operation is supported by the underlying HW (bus, bridge, IOMMU, etc). Example of the case where dma_map_sg() might return 1 'DMA' chunk for the 4 'physical' pages is described here [2] The DMA-mapping framework documentation [3] states that dma_map_sg() returns the numer of the created entries in the DMA address space. However the subsequent calls to dma_sync_sg_for_{device,cpu} and dma_unmap_sg must be called with the original number of entries passed to dma_map_sg. The common pattern in DRM drivers were to assign the dma_map_sg() return value to sg_table->nents and use that value for the subsequent calls to dma_sync_sg_* or dma_unmap_sg functions. Also the code iterated over nents times to access the pages stored in the processed scatterlist, while it should use orig_nents as the numer of the page entries. I've tried to identify all such incorrect usage of sg_table->nents and this is a result of my research. It looks that the incorrect pattern has been copied over the many drivers mainly in the DRM subsystem. Too bad in most cases it even worked correctly if the system used a simple, linear DMA-mapping implementation, for which swapping nents and orig_nents doesn't make any difference. To avoid similar issues in the future, I've introduced a common wrappers for DMA-mapping calls, which operate directly on the sg_table objects. I've also added wrappers for iterating over the scatterlists stored in the sg_table objects and applied them where possible. This, together with some common DRM prime helpers, allowed me to almost get rid of all nents/orig_nents usage in the drivers. I hope that such change makes the code robust, easier to follow and copy/paste safe. The biggest TODO is DRM/i915 driver and I don't feel brave enough to fix it fully. The driver creatively uses sg_table->orig_nents to store the size of the allocate scatterlist and ignores the number of the entries returned by dma_map_sg function. In this patchset I only fixed the sg_table objects exported by dmabuf related functions. I hope that I didn't break anything there. Patches are based on top of Linux next-20200618. The required changes to DMA-mapping framework has been already merged to v5.8-rc1. If possible I would like ask for merging most of the patches via DRM tree.

[PATCH 0/6] remove deprecated i2c_new_device API
by Wolfram Sang 19 Jun '20

19 Jun '20

I want to remove the above API this cycle, and just a few patches have not made it into 5.8-rc1. They have been reviewed and most had been promised to get into linux-next, but well, things happen. So, I hope it is okay for everyone to collect them like this and push them via I2C for 5.8-rc2. One minor exception is the media documentation patch which I simply have missed so far, but it is trivial. And then, finally, there is the removal of the old API as the final patch. Phew, that's been a long ride. I am open for comments, of course.

[PATCH v4 0/3] Support virtio cross-device resources
by David Stevens 19 Jun '20

19 Jun '20

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. [1] https://markmail.org/thread/2ypjt5cfeu3m6lxu [2] https://markmail.org/thread/p5d3k566srtdtute [3] https://markmail.org/thread/j4xlqaaim266qpks v3 -> v4 changes: - Replace dma-buf hooks with virtio dma-buf from v1. - Remove virtio_attach callback, as the work that had been done in that callback is now done on dma-buf export. The documented requirement that get_uuid only be called on attached virtio dma-bufs is also removed. - Rebase and add call to virtio_gpu_notify for ASSIGN_UUID.
