2023-08-16drm/panel: Add driver for JDI LPM102A188ADiogo Ivo
The JDI LPM102A188A is a 2560x1800 IPS panel found in the Google Pixel C. This driver is based on the downstream GPLv2 driver released by Google written by Sean Paul [1], which was then adapted to the newer kernel APIs.

2023-08-14drm/bridge: panel: Add a device link between drm device and panel deviceLiu Ying
Add the device link when panel bridge is attached and delete the link when panel bridge is detached. The drm device is the consumer while the panel device is the supplier. This makes sure that the drm device suspends eariler and resumes later than the panel device, hence resolves problems where the order is reversed, like the problematic case mentioned in the below link.

There are two problems in lsdc_pixel_pll_setup() 1. If kzalloc() fails then call iounmap() to release the resources. 2. Both kzalloc and ioremap does not return error pointers on failure, so using IS_ERR_OR_NULL() checks is a bit confusing and not very right, fix this by changing those to NULL checks instead.

2023-08-11drm/bridge: lvds-codec: Implement atomic_get_input_bus_fmts for LVDS encoderAlexander Stein
atomic_get_input_bus_fmts is only implemented for LVDS decoders, resulting that LVDS encoders only support bus format MEDIA_BUS_FMT_FIXED. This results in warnings like: mxsfb 21c8000.lcdif: Bridge does not provide bus format, assuming MEDIA_BUS_FMT_RGB888_1X24. Please fix bridge driver by handling atomic_get_input_bus_fmts. Fix this by reusing lvds_codec_atomic_get_input_bus_fmts currently used for LVDS decoders. Use RGB888_1X24 for LVDS encoders.

2023-08-08drm/nouveau/sched: Don't pass user flags to drm_syncobj_find_fence()Faith Ekstrand
The flags field in drm_syncobj_find_fence() takes SYNCOBJ_WAIT flags from the syncobj UAPI whereas sync->flags is from the nouveau UAPI. What we actually want is 0 flags which tells it to just try to find the fence and then return without waiting.

The driver depends on CONFIG_OF, so it is not necessary to use of_match_ptr here. Even for drivers that do not depend on CONFIG_OF, it's almost always better to leave out the of_match_ptr(), since the only thing it can possibly do is to save a few bytes of .text if a driver can be used both with and without it.

2023-08-04drm/nouveau: implement new VM_BIND uAPIDanilo Krummrich
This commit provides the implementation for the new uapi motivated by the Vulkan API. It allows user mode drivers (UMDs) to: 1) Initialize a GPU virtual address (VA) space via the new DRM_IOCTL_NOUVEAU_VM_INIT ioctl for UMDs to specify the portion of VA space managed by the kernel and userspace, respectively. 2) Allocate and free a VA space region as well as bind and unbind memory to the GPUs VA space via the new DRM_IOCTL_NOUVEAU_VM_BIND ioctl. UMDs can request the named operations to be processed either synchronously or asynchronously. It supports DRM syncobjs (incl. timelines) as synchronization mechanism. The management of the GPU VA mappings is implemented with the DRM GPU VA manager. 3) Execute push buffers with the new DRM_IOCTL_NOUVEAU_EXEC ioctl. The execution happens asynchronously. It supports DRM syncobj (incl. timelines) as synchronization mechanism. DRM GEM object locking is handled with drm_exec. Both, DRM_IOCTL_NOUVEAU_VM_BIND and DRM_IOCTL_NOUVEAU_EXEC, use the DRM GPU scheduler for the asynchronous paths.

The new VM_BIND UAPI uses the DRM GPU VA manager to manage the VA space. Hence, we a need a way to manipulate the MMUs page tables without going through the internal range allocator implemented by nvkm/vmm. This patch adds a raw interface for nvkm/vmm to pass the resposibility for managing the address space and the corresponding map/unmap/sparse operations to the upper layers.
