drm_gem_shmem_get_sg_table is meant to implement obj->funcs->get_sg_table, for prime exporting. The one we want is drm_gem_shmem_get_pages_sgt, which also handles imported dma-buf, not just native objects. v2: Rebase, this stuff moved around in commit 2f2aa137 Author: Gerd Hoffmann <kraxel@redhat.com> Date: Fri Feb 7 08:46:38 2020 +0100 drm/virtio: move virtio_gpu_mem_entry initialization to new function Acked-by:

- Move the shmem helper section to the drm-mm.rst file, next to the vram helpers. Makes a lot more sense there with the now wider scope. Also, that's where the all the other backing storage stuff resides. It's just the framebuffer helpers that should be in the kms helper section. - Try to clarify which functiosn are for implementing drm_gem_object_funcs, and which for drivers to call directly. At least one driver screwed that up a bit. Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Rob Herring <robh@kernel.org> Cc: Noralf Trønnes <noralf@tronnes.org> Reviewed-by:

I honestly don't exactly understand what's going on here, but the current code is wrong for sure: It calls dma_buf_vunmap without ever calling dma_buf_vmap. What I'm not sure about is whether the WARN_ON is correct: - msm imports dma-buf using drm_prime_sg_to_page_addr_arrays. Which is a pretty neat layering violation of how you shouldn't peek behind the curtain of the dma-buf exporter, but par for course. Note that all the nice new helpers don't (and we should probably have a bit a warning about this in the kerneldoc). - but then in the get_vaddr() in msm_gem.c, we seems to happily wrap a vmap() around any object with ->pages set (so including imported dma-buf). - I'm not seeing any guarantees that userspace can't use an imported dma-buf for e.g. MSM_SUBMIT_CMD_BUF in a5xx_submit_in_rb, so no guarantees that an imported dma-buf won't end up with a ->vaddr set. But even if that WARN_ON is wrong, cleaning up a vmap() done by msm by calling dma_buf_vunmap is the wrong thing to do. v2: Rob said in review that we do indeed have a gap in get_vaddr() that needs to be plugged. But the users I've found aren't legit users on imported dma-buf, so we can just reject that. Reviewed-by:

This code was using get_user_pages*(), in a "Case 2" scenario (DMA/RDMA), using the categorization from [1]. That means that it's time to convert the get_user_pages*() + put_page() calls to pin_user_pages*() + unpin_user_pages() calls. There is some helpful background in [2]: basically, this is a small part of fixing a long-standing disconnect between pinning pages, and file systems' use of those pages.

Dealing with the return value of get_user_pages*() variants has a few classic pitfalls, and this driver found one of them: the return value might be zero, positive, or -errno. And if positive, it might be fewer pages than were requested. And if fewer pages than requested, then the caller should return (via put_page()) the pages that *were* pinned. This driver was doing that *except* that it had a problem with the -errno case, which was being stored in an unsigned int, and which would case an interesting mess if it ever happened: nr_pages would be interpreted as a spectacularly huge unsigned value, rather than a small negative value. Also, it was unnecessarily overriding a potentially informative -errno, with -EINVAL, in some cases. Instead: clamp the nr_pages to zero or positive, so that the error handling works. And return the -errno value from get_user_pages*(), unchanged, if we get one. And explain this with comments, seeing as how it is error-prone.

For historical reasons it's called dev->num_crtcs, which is rather confusing ever since kms was added. But now we have a nice helper, so let's use it for better readability! Only code change is in atomic helpers: vblank support means that dev->irq_enabled must be set too. Another one of these quirky things ... But since it's implied we can simplify that check.

gma500 only uses mode->private_flags to convey the sdvo pixel multiplier from the encoder .mode_fixup() hook to the encoder .mode_set() hook. Those always seems get called as a pair so let's just stuff the pixel multiplier into the encoder itself as there are no state objects we could use in this non-atomic driver. Paves the way for nuking mode->private_flag.
