card: Add support for writeback connectors

2020-08-06T02:09:16+00:00

Add a Card::has_writeback() method to report if the card support
writeback connectors. Similarly to universal planes, add a
KMSXX_DISABLE_WRITEBACK_CONNECTORS environment variable to disable
enumeration of writeback connectors to avoid confusing existing code
that expects all connectors to model an output.

kms++: Add support for missing 8 -and 16-bit RGB formats

2020-08-06T02:09:16+00:00

Add support for the RGB332, XRGB1555 and XRGB4444 formats to the
PixelFormat class, the Python API, and the drawing utilities.

kms++: Add support for the planar YUV formats

2020-08-06T02:09:16+00:00

Add support for the 6 planar YUV formats (YUV and YVU, combined with
420, 422 or 444 subsampling) to the PixelFormat class, the Python API,
and the drawing utilities.

kms++: Add support for semiplanar YUV422 formats (NV16 and NV61)

2020-08-06T02:09:16+00:00

Add support for the NV16 and NV61 pixel formats to the PixelFormat
class, the Python API, and the drawing utilities.

dumbfb: Fix pitch for tri-planar formats

2020-08-06T02:09:16+00:00

The BO pitches are unconditionally set to the frame buffer pitch, for
all planes. This is correct for semiplanar YUV formats, as they
subsample chroma horizontally by two but combined U and V in a single
plane, cancelling each other. For fully planar YUV formats, however, the
horizontal subsampling need to be taken into account to compute the
pitch. Fix it.

dumbfb: Add support tri- or quadri-planar buffers

2020-08-06T02:09:16+00:00

The DumbFrameBuffer class supports up to 4 planes, as required by the
DRM/KMS API, but only considers planes 0 and 1 when constructing the
buffer. Fix it.

card: Rename has_has_universal_planes to has_universal_planes

2020-08-05T22:59:56+00:00

The has_has_universal_planes() method name includes a typo, fix it.

card: Add a method to retrieve the device minor

2020-08-05T22:59:56+00:00

The device minor number is needed to access the debugfs directory
corresponding to the device. Make it available to users through a
get_minor() method on the Card object.

card: add factory function for selecting card by name

2020-05-28T19:08:42+00:00

Uses drmOpen() to do the heavy lifting.

card: add constructor for pre-opened FD

2020-05-28T19:08:42+00:00

This is an escape hatch to let the user do whatever crazy thing he
wants to obtain the DRM fd. This could be from a DRM lease, an FD
passed across a Wayland protocol request, something calculated by
manually walking across the set of DRI cards and selecting specific
criteria, etc.
