drm: Introduce 'power saving policy' drm property

2024-07-10T20:58:19+00:00

The `power saving policy` DRM property is an optional property that can be added to a connector by a driver. This property is for compositors to indicate intent of policy of whether a driver can use power saving features that may compromise the experience intended by the compositor.

drm/uapi: Move drm_color_ctm_3x4 out from drm_mode.h

2024-05-07T11:14:30+00:00

drm_color_ctm_3x4 is some undocumented amgdpu private uapi and thus has no business being in drm_mode.h. At least move it to some amdgpu specific header, albeit with the wrong namespace as maybe something somewhere is using this already?

drm: Introduce plane SIZE_HINTS property

2024-04-11T15:28:58+00:00

Add a new immutable plane property by which a plane can advertise a handful of recommended plane sizes. This would be mostly exposed by cursor planes as a slightly more capable replacement for the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare a one size fits all limit for the whole device. Currently eg. amdgpu/i915/nouveau just advertize the max cursor size via the cursor size caps. But always using the max sized cursor can waste a surprising amount of power, so a better strategy is desirable. Most other drivers don't specify any cursor size at all, in which case the ioctl code just claims that 64x64 is a great choice. Whether that is actually true is debatable. A poll of various compositor developers informs us that blindly probing with setcursor/atomic ioctl to determine suitable cursor sizes is not acceptable, thus the introduction of the new property to supplant the cursor size caps. The compositor will now be free to select a more optimal cursor size from the short list of options. Note that the reported sizes (either via the property or the caps) make no claims about things such as plane scaling. So these things should only really be consulted for simple "cursor like" use cases.

This reverts commit 85863a4e16e77079ee14865905ddc3ef9483a640. 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.

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; }; Acked-by: Harry Wentland Acked-by: Sebastian Wick Signed-off-by: Jessica Zhang Reviewed-by: Dmitry Baryshkov Signed-off-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20231027-solid-fill-v7-2-780188bfa7b2@quicinc.com
