drm/lease: allow empty leases
This can be used to create a separate DRM file description, thus creating a new GEM handle namespace.
My use-case is wlroots. The library splits responsibilities between separate components: the GBM allocator creates buffers, the GLES2 renderer uses EGL to import them and render to them, the DRM backend imports the buffers and displays them. wlroots has a modular architecture, and any of these components can be swapped and replaced with something else. For instance, the pipeline can be set up so that the DRM dumb buffer allocator is used instead of GBM and the Pixman renderer is used instead of GLES2. Library users can also replace any of these components with their own custom one.
DMA-BUFs are used to pass buffer references across components. We could use GEM handles instead, but this would result in pain if multiple GPUs are in use: wlroots copies buffers across GPUs as needed. Importing a GEM handle created on one GPU into a completely different GPU will blow up (fail at best, mix unrelated buffers otherwise).
Everything is fine if all components use Mesa. However, this isn't always desirable. For instance when running with DRM dumb buffers and the Pixman software renderer it's unfortunate to depend on GBM in the DRM backend just to turn DMA-BUFs into FB IDs. GBM loads Mesa drivers to perform an action which has nothing driver-specific. Additionally, drivers will fail the import if the 3D engine can't use the imported buffer, for instance amdgpu will refuse to import DRM dumb buffers [1]. We might also want to be running with a Vulkan renderer and a Vulkan allocator in the future, and GBM wouldn't be welcome in this setup.
To address this, GBM can be side-stepped in the DRM backend, and can be replaced with drmPrimeFDToHandle calls. However because of GEM handle reference counting issues, care must be taken to avoid double-closing the same GEM handle. In particular, it's not possible to share a DRM FD with GBM or EGL and perform some drmPrimeFDToHandle calls manually.
So wlroots needs to re-open the DRM FD to create a new GEM handle namespace. However there's no guarantee that the file-system permissions will be set up so that the primary FD can be opened by the compsoitor. On modern systems seatd or logind is a privileged process responsible for doing this, and other processes aren't expected to do it. For historical reasons systemd still allows physically logged in users to open primary DRM nodes, but this doesn't work on non-systemd setups and it's desirable to lock them down at some point.
Some might suggest to open the render node instead of re-opening the primary node. However some systems don't have a render node at all (e.g. no GPU, or a split render/display SoC).
Solutions to this issue have been discussed in [2]. One solution would be to open the magic /proc/self/fd/<fd> file, but it's a Linux-specific hack (wlroots supports BSDs too). Another solution is to add support for re-opening a DRM primary node to seatd/logind, but they don't support it now and really haven't been designed for this (logind would need to grow a completely new API, because it assumes unique dev_t IDs). Also this seems like pushing down a kernel limitation to user-space a bit too hard.
Another solution is to allow creating empty DRM leases. The lessee FD would have its own GEM handle namespace, so wouldn't conflict wth GBM/EGL. It would have the master bit set, but would be able to manage zero resources. wlroots doesn't intend to share this FD with any other process.
All in all IMHO that seems like a pretty reasonable solution to the issue at hand.
Note, I've discussed with Jonas Ådahl and Mutter plans to adopt a similar design in the future.
Example usage in wlroots is available at [3]. IGT test available at [4].

Force-probing a connector can be slow and cause flickering. As this affects the global KMS state, let's make it so only the DRM master can force-probe a connector.
Non-master DRM clients won't be able to force-probe a connector anymore. Instead, KMS will perform a regular read-only connector query.

drm: report dp downstream port type as a subconnector property
Currently, downstream port type is only reported in debugfs. This information should be considered important since it reflects the actual physical connector type. Some userspace (e.g. window compositors) may want to show this info to a user.
The 'subconnector' property is already utilized for DVI-I and TV-out for reporting connector subtype.
The initial motivation for this feature came from i2c test [1]. It is supposed to be skipped on VGA connectors, but it cannot detect VGA over DP and fails instead.
v2: - Ville: utilized drm_dp_is_branch() - Ville: implement DP 1.0 downstream type info - Replaced create_dp_properties with add_dp_subconnector_property - Added dp_set_subconnector_property helper
v4: - Ville: add DP1.0 best assumption about subconnector - Ville: assume DVI is DVI-D - Ville: reuse Writeback enum value for Virtual subconnector - Renamed #defines: HDMI -> HDMIA, DP -> DisplayPort
v5: rebase
v6: - Jani Nikula: renamed a function name - Jani Nikula: addressed the issues with documentation

drm: Add HDR source metadata property
This patch adds a blob property to get HDR metadata information from userspace. This will be send as part of AVI Infoframe to panel.
It also implements get() and set() functions for HDR output metadata property.The blob data is received from userspace and saved in connector state, the same is returned as blob in get property call to userspace.
v2: Rebase and modified the metadata structure elements as per Ville's POC changes.
v3: No Change
v4: Addressed Shashank's review comments
v5: Rebase.
v6: Addressed Brian Starkey's review comments, defined new structure with header for dynamic metadata scalability. Merge get/set property functions for metadata in this patch.
v7: Addressed Jonas Karlman review comments and defined separate structure for infoframe to better align with CTA 861.G spec. Added Shashank's RB.
v8: Addressed Ville's review comments. Moved sink metadata structure out of uapi headers as suggested by Jonas Karlman.
v9: Rebase and addressed Jonas Karlman review comments.
v10: Addressed Ville's review comments, dropped the metdata_changed state variable as its not needed anymore.

Interpreting it as a 0.16 fixed point means we can't accurately represent 1.0. Which is one of the values we really should be able to represent.
Since most (all?) luts have lower precision this will only affect rounding of 0xffff.
