Create GEM objects with drm_gem_cma_create_object_default_funcs(), which allocates the object and sets CMA's default object functions. Corresponding callbacks in struct drm_driver are cleared. No functional changes are made. Driver and object-function instances use the same callback functions, with the exception of vunmap. The implementation of vunmap is empty and left out in CMA's default object functions. v3: * convert to DRIVER_OPS macro in a separate patch Signed-off-by:

The kirin drivers uses drm_gem_cma_dumb_create_internal() for its .dumb_create implementation. The function is meant for internal use only by drivers that require additional buffer setup. Kirin does not do an additional setup, so convert it over to drm_gem_cma_dumb_create(). Signed-off-by:

- Ditch the ->pages array - Make it a private gem bo, which means no shmem object, which means fireworks if anyone calls drm_gem_object_get_pages. But we've just made sure that's all covered. v2: Rebase v3: I forgot to remove the page_count mangling from the free path too. Noticed by Boris while testing.

Just a bit of light paranoia. Also sprinkle this check over drm_gem_shmem_get_sg_table, which should only be called when exporting, same for the pin/unpin functions, on which it relies to work correctly. Acked-by:

This patch adds support for Kaohsiung Opto-Electronics Inc. 10.1" TX26D202VM0BWA WUXGA(1920x1200) TFT LCD panel with LVDS interface. The panel has dual LVDS channels. My panel is manufactured by US Micro Products(USMP). There is a tag at the back of the panel, which indicates the panel type is 'TX26D202VM0BWA' and it's made by KOE in Taiwan. The panel spec from USMP can be found at: https://www.usmicroproducts.com/sites/default/files/datasheets/USMP-T101-192120NDU-A0.pdf The below panel spec from KOE is basically the same to the one from USMP. However, the panel type 'TX26D202VM0BAA' is a little bit different. It looks that the two types of panel are compatible with each other. http://www.koe.j-display.com/upload/product/TX26D202VM0BAA.pdf Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by:

This is already taken care of by drm_atomic_helper_shutdown(), and in that case only for the CRTC which are actually on. Only tricky bit here is that we kill the interrupt handling before we shut down crtc, so need to reorder that. Acked-by:

Currently this seems to work by converting the sgt into a pages array, and then treating it like a native object. Do the right thing and redirect mmap to the exporter. With this nothing is calling get_pages anymore on imported dma-buf, and we can start to remove the use of the ->pages array for that case. v2: Rebase Tested-by:

There's no direct harm, because for the shmem helpers these are noops on imported buffers. The trouble is in the locks these take - I want to change dma_buf_vmap locking, and so need to make sure that we only ever take certain locks on one side of the dma-buf interface: Either for exporters, or for importers. v2: Change the control flow less compared to what's there (Thomas) Tested-by:

drm_gem_shmem_get_sg_table is meant to implement obj->funcs->get_sg_table, for prime exporting.

- 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:
