drm/drm_property: make replace_property_blob_from_id a DRM helper

2023-12-13T20:09:53+00:00

Place it in drm_property where drm_property_replace_blob and
drm_property_lookup_blob live. Then we can use the DRM helper for
driver-specific KMS properties too.

Revert "drm: Introduce pixel_source DRM plane property"

2023-12-04T19:33:10+00:00

This reverts commit e50e5fed41c7eed2db4119645bf3480ec43fec11.

Although the Solid Fill planes patchset got all reviews and
acknowledgements, it doesn't fulfill requirements for the new uABI. It
has neither corresponding open-source userspace implementation nor the
IGT tests coverage. Reverting this patchset until userspace obligations
are fulfilled.

drm: Introduce solid fill DRM plane property

2023-12-01T23:56:48+00:00

Document and add support for solid_fill property to drm_plane. In
addition, add support for setting and getting the values for solid_fill.

To enable solid fill planes, userspace must assign a property blob to
the "solid_fill" plane property containing the following information:

struct drm_mode_solid_fill {
	u32 r, g, b, pad;
};

drm: Introduce pixel_source DRM plane property

2023-12-01T23:56:46+00:00

Add support for pixel_source property to drm_plane and related
documentation. In addition, force pixel_source to
DRM_PLANE_PIXEL_SOURCE_FB in DRM_IOCTL_MODE_SETPLANE as to not break
legacy userspace.

This enum property will allow user to specify a pixel source for the
plane. Possible pixel sources will be defined in the
drm_plane_pixel_source enum.

Currently, the only pixel sources are DRM_PLANE_PIXEL_SOURCE_FB (the
default value) and DRM_PLANE_PIXEL_SOURCE_NONE.

drm/atomic: Add support for mouse hotspots

2023-11-24T10:57:56+00:00

Atomic modesetting code lacked support for specifying mouse cursor
hotspots. The legacy kms DRM_IOCTL_MODE_CURSOR2 had support for setting
the hotspot but the functionality was not implemented in the new atomic
paths.

Due to the lack of hotspots in the atomic paths userspace compositors
completely disable atomic modesetting for drivers that require it (i.e.
all paravirtualized drivers).

This change adds hotspot properties to the atomic codepaths throughtout
the DRM core and will allow enabling atomic modesetting for virtualized
drivers in the userspace.

drm: allow DRM_MODE_PAGE_FLIP_ASYNC for atomic commits

2023-11-23T16:12:49+00:00

If the driver supports it, allow user-space to supply the
DRM_MODE_PAGE_FLIP_ASYNC flag to request an async page-flip.
Set drm_crtc_state.async_flip accordingly.

Document that drivers will reject atomic commits if an async
flip isn't possible. This allows user-space to fall back to
something else. For instance, Xorg falls back to a blit.
Another option is to wait as close to the next vblank as
possible before performing the page-flip to reduce latency.

drm: Refuse to async flip with atomic prop changes

2023-11-23T16:12:38+00:00

Given that prop changes may lead to modesetting, which would defeat the
fast path of the async flip, refuse any atomic prop change for async
flips in atomic API. The only exception is the framebuffer ID to flip
to. Currently the only plane type supported is the primary one.
