Now that we finally have a sane way to keep port allocations around, use it to fix the potential unchecked ->port accesses that nouveau makes by making sure we keep the mst port allocated for as long as it's drm_connector is accessible. Additionally, now that we've guaranteed that mstc->port is allocated for as long as we keep mstc around we can remove the connector registration checks for codepaths which release payloads, allowing us to release payloads on active topologies properly. These registration checks were only required before in order to avoid situations where mstc->port could technically be pointing at freed memory. Signed-off-by:

There is no need to look at the port's VCPI allocation before calling drm_dp_mst_deallocate_vcpi(), as we already have msto->disabled to let us avoid cleaning up an msto more then once. The DP MST core will never call drm_dp_mst_deallocate_vcpi() on it's own, which is presumably what these checks are meant to protect against. More importantly though, we're about to stop clearing mstc->port in the next commit, which means if we could potentially hit a use-after-free error if we tried to check mstc->port->vcpi here. So to make life easier for anyone who bisects this code in the future, use msto->disabled instead to check whether or not we need to deallocate VCPI instead. Signed-off-by:

Just like i915 and nouveau, it's a good idea for us to hold a malloc reference to the port here so that we never pass a freed pointer to any of the DP MST helper functions. Also, we stop unsetting aconnector->port in dm_dp_destroy_mst_connector(). There's literally no point to that assignment that I can see anyway. Signed-off-by:

Up until now, freeing payloads on remote MST hubs that just had ports removed has almost never worked because we've been relying on port validation in order to stop us from accessing ports that have already been freed from memory, but ports which need their payloads released due to being removed will never be a valid part of the topology after they've been removed. Since we've introduced malloc refs, we can replace all of the validation logic in payload helpers which are used for deallocation with some well-placed malloc krefs. This ensures that regardless of whether or not the ports are still valid and in the topology, any port which has an allocated payload will remain allocated in memory until it's payloads have been removed - finally allowing us to actually release said payloads correctly.

While this isn't a complete fix, this will improve the reliability of drm_dp_get_last_connected_port_and_mstb() pretty significantly during hotplug events, since there's a chance that the in-memory topology tree may not be fully updated when drm_dp_get_last_connected_port_and_mstb() is called and thus might end up causing our search to fail on an mstb whose topology refcount has reached 0, but has not yet been removed from it's parent. Ideally, we should further fix this problem by ensuring that we deal with the potential for racing with a hotplug event, which would look like this: * drm_dp_payload_send_msg() retrieves the last living relative of mstb with drm_dp_get_last_connected_port_and_mstb() * drm_dp_payload_send_msg() starts building payload message At the same time, mstb gets unplugged from the topology and is no longer the actual last living relative of the original mstb * drm_dp_payload_send_msg() tries sending the payload message, hub times out * Hub timed out, we give up and run away-resulting in the payload being leaked This could be fixed by restarting the drm_dp_get_last_connected_port_and_mstb() search whenever we get a timeout, sending the payload to the new mstb, then repeating until either the entire topology is removed from the system or drm_dp_get_last_connected_port_and_mstb() fails. But since the above race condition is not terribly likely, we'll address that in a later patch series once we've improved the recovery handling for VCPI allocations in the rest of the DP MST helpers.

The current way of handling refcounting in the DP MST helpers is really confusing and probably just plain wrong because it's been hacked up many times over the years without anyone actually going over the code and seeing if things could be simplified. To the best of my understanding, the current scheme works like this: drm_dp_mst_port and drm_dp_mst_branch both have a single refcount. When this refcount hits 0 for either of the two, they're removed from the topology state, but not immediately freed. Both ports and branch devices will reinitialize their kref once it's hit 0 before actually destroying themselves. The intended purpose behind this is so that we can avoid problems like not being able to free a remote payload that might still be active, due to us having removed all of the port/branch device structures in memory, as per: commit 91a25e46 ("drm/dp/mst: deallocate payload on port destruction") Which may have worked, but then it...

Add the KMS plane rotation property to the DRM rockchip driver, for SoCs RK3328, RK3368 and RK3399. RK3288 only supports rotation at the display level (i.e. CRTC), but for now we are only interested in plane rotation. This commit only adds support for the value of reflect-y and reflect-x (i.e. mirroring). Note that y-mirroring is not compatible with YUV. The following modetest commands would test this feature, where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x. X mirror: modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17 Y mirror: modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33 XY mirror: modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49 Signed-off-by:

Currently, YUV hardware overlays are converted to RGB using a color space conversion different than BT.601. The result is that colors of e.g. NV12 buffers don't match colors of YUV hardware overlays. In order to fix this, enable YUV2YUV and set appropriate coefficients for formats such as NV12 to be displayed correctly. This commit was tested using modetest, gstreamer and chromeos (hardware accelerated video playback). Before the commit, tests rendering with NV12 format resulted in colors not displayed correctly.

The following happened when migrating an old fbdev driver to DRM: The Integrator/CP PL111 supports 16BPP but only ARGB1555/ABGR1555 or XRGB1555/XBGR1555 i.e. the maximum depth is 15. This makes the initialization of the framebuffer fail since the code in drm_fb_helper_single_fb_probe() assigns the same value to sizes.surface_bpp and sizes.surface_depth. I.e. it simply assumes a 1-to-1 mapping between BPP and depth, which is true in most cases but not for this hardware that only support odd formats. To support the odd case of a driver supporting 16BPP with only 15 bits of depth, this patch will make the code loop over the formats supported on the primary plane on each CRTC managed by the FB helper and cap the depth to the maximum supported on any primary plane. On the PL110 Integrator, this makes drm_mode_legacy_fb_format() select DRM_FORMAT_XRGB1555 which is acceptable for this driver, and thus we get framebuffer, penguin and console on the Integrator/CP.

Build tested with arm and x86. v2: - prefer forward declarations when possible (Laurent Pinchart) - sort include files (Laurent Pinchart) Signed-off-by:

The gem drivers use shmemfs to allocate backing storage for gem objects. On Samsung Chromebook Plus, the drm/rockchip driver may call rockchip_gem_get_pages -> drm_gem_get_pages -> shmem_read_mapping_page to pin a lot of pages, breaking the page reclaim mechanism and causing oom-killer invocation. E.g. when the size of a zone is 3.9 GiB, the inactive_ratio is 5. If active_anon / inactive_anon < 5 and all pages in the inactive_anon lru are pinned, page reclaim would keep scanning inactive_anon lru without reclaiming memory. It breaks page reclaim when the rockchip driver only pins about 1/6 of the anon lru pages. Mark these pinned pages as unevictable to avoid the premature oom-killer invocation.

Add forward declaration and pull in include file to make drm_framebuffer.h self contained. While add it order include files alphabetically. The use of TASK_COMM_LEN is the reason for including sched.h. I could not see any good way to avoid this dependency, and users of drm_framebuffer.comm already use TASK_COMM_LEN to check for length etc. v2: - Added forward declaration of drm_gem_object (Noralf) - Added ack from Noralf Signed-off-by:

Move DRM_SWITCH_POWER out of drmP.h to allow users to get rid of the drmP include. Moved to drm_device.h because drm_device.switch_power_state is the only user. Converted to enum and added sparse kerneldoc comments. Signed-off-by:

Updated comment style to kernel-doc format in drm_device.h In struct drm_device there are 12 struct members without doc: - registered - filelist_mutex - filelist - irq - vbl_lock - event_lock - hose - sigdata - sigdata.context - sigdata.lock - agp_buffer_map - agp_buffer_token They all need proper documentation, a task left for someone that knows their usage. drm_device is not plugged into Documentation/gpu/drm-internals.rst as this would create a new load of warnings.

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.
