We want to stop using plane->fb with atomic driver, so stop looking at it. I have no idea what this code is trying to achieve. There is no corresponding check in the enable path. Also since arc_pgu_set_pxl_fmt() will anyway oops if there is no fb I'm going to assuming that I can just remove the check entirely. There seems to be a general shortage of .atomic_check() in this driver... Cc: Alexey Brodkin <abrodkin@synopsys.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by:

If we can use an unmappable ring, try to pin it out of the mappable aperture. This simple layout preference is to try and keep the mappable aperture reserved and available to handle GGTT mmapping requests from userspace without causing evictions and GPU stalls. Signed-off-by:

To no surprise (since we've flip-flopped over the use of PIN_HIGH a few times), doing a search by address over a pathologically fragmented address space is exceeding slow. To protect ourselves from nearly unbounded latency (think searching a million holes while under struct_mutex), limit the search for the highest available hole and fallback to best-fit if it fails. In the pathologically fragmented case, such as igt/gem_ctx_thrash, the effect is dramatic, bringing the runtime down from hours to seconds (depending on how many other slow searches you hit, e.g. alloc_iova() and alloc_vmap_area() both degrade to a slow rbtree walk after their small cache is exhausted). For the real world, the number of search steps is unlikely to be significant as we should only need to search once per new context. Signed-off-by:

Searching for an available hole by address is slow, as there no guarantee that a hole will be available and so we must walk over all nodes in the rbtree before we determine the search was futile. In many cases, the caller doesn't strictly care for the highest available hole and was just opportunistically laying out the address space in a preferred order. In such cases, the caller can accept any address and would rather do so then do a slow walk. To be able to mix search strategies, the caller wants to tell the drm_mm how long to spend on the search. Without a good guide for what should be the best split, start with a request to try once at most. That is return the top-most (or lowest) hole if it fulfils the alignment and size requirements. v2: Documentation, by why of example (selftests) and kerneldoc. Signed-off-by:

Chris Wilson authored
As we keep an rbtree of available holes sorted by their size, we can very easily determine if there is any hole large enough that might satisfy the allocation request. This helps when dealing with a highly fragmented address space and a request for a search by address. To cache the largest size, we convert into the cached rbtree variant which tracks the leftmost node for us. However, currently we sorted into ascending size order so the leftmost node is the smallest, and so to make it the largest hole we need to invert our sorting. Signed-off-by:

Use new return type vm_fault_t for fault and huge_fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Commit 1c8f4220 ("mm: change return type to vm_fault_t") Previously vm_insert_page() returns err which driver mapped into VM_FAULT_* type. The new function vmf_ insert_page() will replace this inefficiency by returning VM_FAULT_* type. Signed-off-by:

There's an ongoing effort to remove VLAs[1] from the kernel to eventually turn on -Wvla. The vla in reg_write_range is based on the length of data passed. The one use of a non-constant size for this range is bounded by the size buffer passed to hdmi_infoframe_pack which is a fixed size. Switch to this upper bound.

Commit bc61c975 ("drm/gma500: Move GEM BO to drm_framebuffer") moved the gtt_range structure, from being in psb_framebuffer and embedding the GEM object, to being placed in the drm_framebuffer with the gtt_range being derived from the GEM object. The conversion missed out the Medfield subdriver, which was not being built in the default drm-misc config. Do the trivial fixup here. Signed-off-by:

Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle and destroy functions the same as the GEM framebuffer helper, we can reuse those. Signed-off-by:

The backlight 1st update was in the otm8009a_prepare() function for a bad reason: backlight was not working in video mode and the otm8009a_prepare() is in command mode for the init sequence.

Backlight updates was not working anymore since the good implementation of the DSI low-power mode in the DSI host driver. After a longer analysis, the backlight updates in DSI video mode require the DSI high- speed mode. Note: it is important to keep the DSI low-power mode for the rest of the driver as init sequence, sleep in/out... DSI commands work in low-power mode. Signed-off-by:

Add device_link from panel device (supplier) to DRM device (consumer) when drm_panel_attach() is called. This patch should protect the master DRM driver if an attached panel driver unbinds while it is in use. The device_link should make sure the DRM device is unbound before the panel driver becomes unavailable. The device_link is removed when drm_panel_detach() is called. The drm_panel_detach() should be called by the consumer DRM driver, not the panel driver, otherwise both drivers are racing to delete the same link. Signed-off-by:
