"GPL-2.0-only" in the license header was incorrectly changed to the now deprecated "GPL-2.0". Fix.

drm/gpuvm: Dual-licence the drm_gpuvm code GPL-2.0 OR MIT

2023-10-17T08:55:30Z

Dual-licence in order to make it possible for other non-GPL os'es to re-implement the code. The use of EXPORT_SYMBOL_GPL() is intentionally left untouched to prevent use of drm_gpuvm as a proxy for non-GPL drivers to access GPL-only kernel symbols. Much of the ideas and algorithms used in the drm_gpuvm code is already present in one way or another in MIT-licensed code.

Merge tag 'drm-misc-next-2023-09-27' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

2023-09-28T22:27:15Z

drm-misc-next for v6.7-rc1: UAPI Changes: - drm_file owner is now updated during use, in the case of a drm fd opened by the display server for a client, the correct owner is displayed. - Qaic gains support for the QAIC_DETACH_SLICE_BO ioctl to allow bo recycling. Cross-subsystem Changes: - Disable boot logo for au1200fb, mmpfb and unexport logo helpers. Only fbcon should manage display of logo. - Update freescale in MAINTAINERS. - Add some bridge files to bridge in MAINTAINERS. - Update gma500 driver repo in MAINTAINERS to point to drm-misc. Core Changes: - Move size computations to drm buddy allocator. - Make drm_atomic_helper_shutdown(NULL) a nop. - Assorted small fixes in drm_debugfs, DP-MST payload addition error handling. - Fix DRM_BRIDGE_ATTACH_NO_CONNECTOR handling. - Handle bad (h/v)sync_end in EDID by clipping to htotal. - Build GPUVM as a module. Driver Changes: - Simple drivers don't need to cache prepared result. - Call drm_atomic_helper_shutdown() in shutdown/unbind for a whole lot more drm drivers. - Assorted small fixes in amdgpu, ssd130x, bridge/it6621, accel/qaic, nouveau, tc358768. - Add NV12 for komeda writeback. - Add arbitration lost event to synopsis/dw-hdmi-cec. - Speed up s/r in nouveau by not restoring some big bo's. - Assorted nouveau display rework in preparation for GSP-RM, especially related to how the modeset sequence works and the DP sequence in relation to link training. - Update anx7816 panel. - Support NVSYNC and NHSYNC in tegra. - Allow multiple power domains in simple driver.

drm/gpuvm: allow building as module

2023-09-25T23:58:28Z

Currently, the DRM GPUVM does not have any core dependencies preventing a module build. Also, new features from subsequent patches require helpers (namely drm_exec) which can be built as module.

drm/gpuvm: rename struct drm_gpuva_manager to struct drm_gpuvm

2023-09-25T23:51:28Z

Rename struct drm_gpuva_manager to struct drm_gpuvm including corresponding functions. This way the GPUVA manager's structures align very well with the documentation of VM_BIND [1] and VM_BIND locking [2]. It also provides a better foundation for the naming of data structures and functions introduced for implementing a common dma-resv per GPU-VM including tracking of external and evicted objects in subsequent patches.
