The "unode" pointer cannot be NULL here and checking for it causes Smatch warnings: drivers/gpu/drm/udl/udl_main.c:259 udl_get_urb_locked() warn: can 'unode' even be NULL? Fortunately, it's just harmless dead code which can be removed. It's left over from commit c5c354a3 ("drm/udl: Fix inconsistent urbs.count value during udl_free_urb_list()"). Reported-by:

Create a symlink pointing to USB Type-C connector for DRM connectors when they are created. The link will be created only if the firmware is able to describe the connection beween the two connectors. Currently, even if a display uses a USB Type-C port, there is no way for the userspace to find which port is used for which display. With the symlink, display information would be accessible from Type-C connectors and port information would be accessible from DRM connectors. Associating the two subsystems, userspace would have potential to expose and utilize more complex information. ChromeOS intend to use this information for metrics collection. For example, we want to tell which port is deriving which displays. Also, combined with USB PD information, we can tell whether user is charging their device through display. Chromium patch for parsing the symlink from the kernel is at http://crrev.com/c/4317207. We already have a framework in typec port-mapper.c where it goes through component devices and runs the bind functions for those with matching _PLD (physical location of device). https://elixir.bootlin.com/linux/v5.18.1/source/drivers/usb/typec/ port-mapper.c Since _PLD is ACPI specific field, this linking would only work on ACPI x86 as long as _PLD field for Type-C connectors and DRM connectors are correctly added to the firmware. Currently, USB ports and USB4 ports are added as components to create a symlink with Type C connector. USB: https://lore.kernel.org/all/20211223082349.45616-1-heikki.krogerus @linux.intel.com/ USB4: https://lore.kernel.org/all/20220418175932.1809770-3-wonchung@google.com/ So, we follow the same pattern in this patch.

Expose DRM connector id in device sysfs so that we can map the connector id to the connector syspath. Currently, even if we can derive the connector id from modeset, we do not have a way to find the corresponding connector's syspath. This is helpful when determining the root connector of MST tree. When a tree of multiple MST hub is connected to the system, modeset describes the tree in the PATH blob. For example, consider the following scenario. +-------------+ | Source | +-------------+ | (Device) | | BranchX | | | | (MST) | | [conn6]--->| [port1]--->DisplayA +-------------+ | | | | +-------------+ | | | BranchY | | | | (MST) | | [port2]--->| [port1]----->DisplayB +-------------+ | | | [port2]----->DisplayC +-------------+ DPMST connector of DisplayA would have "mst:6-1" PATH. DPMST connector of DisplayB would have "mst:6-2-1" PATH. DPMST connector of DisplayC would have "mst:6-2-2" PATH. Given that connector id of 6 is the root of the MST connector tree, we can utilize this patch to parse through DRM connectors sysfs and find which connector syspath corresponds to the root connector (id == 6). ChromeOS intend to use this information for metrics collection. For example, we want to tell which port is deriving which displays even with a MST hub. Chromium patch for parsing DRM connector id from the kernel is at http://crrev.com/c/4317207. Signed-off-by: -

Let’s establish a merge plan for Xe, by writing down clear pre-merge goals, in order to avoid unnecessary delays. This initial document starts with a TODO list containing items with clear and measurable key results. Xe’s initial pull request should only be sent to dri-devel after all the items are clearly resolved. Since many of them involve some level of a community consensus, in many cases, the consensus will be reached in follow-up patches to this document with more details of the API or helpers that will be developed or modified. Besides of the items that are highlighted in this document, it is important to highlight that Oded, has been volunteered to give the overall ack on Xe driver as the way to confirm that it looks good for upstream. v2: Incorporated Daniel's feedback: - Do not make long-running compute a blocker. - Add a mention to drm-exec that that ties to vm_bind and long-running compute jobs. Then I also added GPUVA since I recently noticed that this ties also to the work Matt is doing on that front. - Added the devcoredump section. - Add the mention to Oded being volunteered for the overall ack. v3: Reword a bit the Async VM_BIND to incorporate Daniel's feedback on ensuring the async vmbind consensus explicitly include Mesa, besides other kernel drivers.

Before commit bc0d7fde ("drm: vkms: Supports to the case where primary plane doesn't match the CRTC"), the composition was executed on top of the primary plane. Therefore, the primary plane was not able to support the alpha channel. After commit bc0d7fde, this is possible, as the composition is now executed on top of the CRTC. So, allow all planes to support the alpha channel, making full alpha blending possible in vkms. Signed-off-by:

Move the implementation of fb_pgprotect() to fbdev.c and include <asm/fb.h>. Fixes the following warning: ../arch/x86/video/fbdev.c:14:5: warning: no previous prototype for 'fb_is_primary_device' [-Wmissing-prototypes] 14 | int fb_is_primary_device(struct fb_info *info) | ^~~~~~~~~~~~~~~~~~~~ Just including <asm/fb.h> results in a number of built-in errors about undefined function. Moving fb_pgprotect() to the source file avoids the required include statements in the header. The function is only called occasionally from fb_mmap(), [1] so having it as static inline had no benefit. While at it, fix the codying style in fbdev.c.

The CSC matrices were stored as separate matrix for each colorspace, and if we wanted a limited or full RGB output. This created some gaps in our support and we would not always pick the relevant matrix.

YUV444 and YUV422 actually require the same matrix, but programmed differently. We've dealt with it in the past by having two matrices, with the one for YUV444 reordered to accomodate the hardware.

On VC4, the TV margins on the HDMI connector are implemented by scaling the planes. However, if only the TV margins or the connector are changed by a new state, the planes ending up on that connector won't be. Thus, they won't be updated properly and we'll effectively ignore that change until the next commit affecting these planes. Let's make sure to add all the planes attached to the connector so that we can update them properly. Reviewed-by:
