drm/hyperv: Switch to drm_atomic_helper_crtc_create_state

2026-08-31T13:09:26+00:00

The hyperv crtc implementation uses the deprecated drm_atomic_helper_crtc_reset() as its reset hook. Switch to drm_atomic_helper_crtc_create_state() instead.

drm_hyperv: Remove support for synth video protocol of old Hyper-V hosts

2026-08-24T12:40:11+00:00

With the overall removal of Linux support for running on Hyper-V hosts earlier than WS2016 and Windows 10, it's no longer necessary to support older synthetic video protocols. Remove the support.

drm/hyperv: Move MODULE_DEVICE_TABLE to the device_id arrays

2026-07-20T14:33:49+00:00

It matches the usual coding style to have the MODULE_DEVICE_TABLE macro directly after the respective arrays.

drm/hyperv: Explicitly set subvendor and subdevice for pci match array

2026-07-20T14:33:25+00:00

.subvendor and .subdevice were set to 0 implicitly, so only devices with these two values set to 0 in hardware can probe automatically. Make this requirement explicit. While touching this array item, also make use of the pci macro designed for that case.

drm/hyperv: Unregister pci driver in error path before module unload

2026-07-20T14:33:24+00:00

The pci driver must not kept registered if the module is unloaded after vmbus_driver_register() fails. So check the return value of vmbus_driver_register() and unregister the pci driver on failure.

drm/hyperv: Use "hv_drm_" as symbol name prefix

2026-05-29T11:08:30+00:00

Function and structure names in the Hyper-V DRM driver currently use "hyperv_" as the prefix. This conflicts with usage in core Hyper-V and VMBus code, and incorrectly implies that functions and structures in this driver apply generically to Hyper-V. A specific conflict arises for "hyperv_init", which is an initcall for generic Hyper-V initialization on arm64. The conflict prevents the use of initcall_blacklist on the kernel boot line to skip loading this driver. Fix this by substituting "hv_drm_" as the prefix for all functions and structures in this driver. In most places, this is replacing "hyperv_" with "hv_drm_". In a few places, the substitution results in "hv_drm_drm_", which has been collapsed to just "hv_drm_". In two cases, the existing prefix is a bare "hv" (including in the to_hv() macro), which has been replaced with "hv_drm" for consistency. The changes are all mechanical text substitution in symbol names. There are no other code or functional changes.
