2022-06-09card: Add support for writeback connectorsLaurent Pinchart
Enable enumeration of writeback connectors if both libdrm and the device support it. The new Card::has_writeback() method report if the card support writeback connectors. Existing code that expect all connectors to model an output may be confused by the sudden availability of new connectors. To handle this issue, - add a KMSXX_DISABLE_WRITEBACK_CONNECTORS environment variable to disable enumeration of writeback connectors, similarly to universal planes ; and - ignore writeback connectors where no specific connector is requested (Card::get_first_connected_connector(), ResourceManager::reserve_connector() if no connector name is specified, and applications that use all connected outputs).

Looks like RPi gives 0xff as possible_crtcs, even if there's only one crtc. The current code throws an exception in that case. Fix this by just ignoring non-existent possible crtcs. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2020-08-10dumbfb: Fix pitch for tri-planar formatsLaurent Pinchart
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.

2020-08-10dumbfb: Add support tri- or quadri-planar buffersLaurent Pinchart

2020-05-28card: add constructor for pre-opened FDMatt Hoosier
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.

2020-01-16Link libfmt in header-only modeMatt Hoosier
This saves us the trouble of having a copy of its shared library installed into the target filesystem, which would conflict with an independently packaged copy. Only the headers are needed to accomplish the usages that Kms++ makes.

2019-11-18Allow making extframebuffer and dmabufframebuffer with modifiersMatt Hoosier
Many GPUs use bandwidth compression or tiling, and this information must be passed along to KMS when constructing the framebuffer object around the GEM handle or prime filedescriptor. Add an vector of modifiers as an optional parameter to both of these classes. Bump the minimum required version of libdrm to 2.4.17 to ensure drmModeAddFB2WithModifiers() is available.

2019-01-17card: another try with card constructorsTomi Valkeinen
Let's try again with the card constructors. Card::open_modesetting_card() is removed. The main constructor is Card(const std::string& dev_path = ""). If dev_path is set, the device node with that path is used. If dev_path is not set, the behavior is similar as previously, except a modeset capable card is used at the third step: - If KMSXX_DEVICE env variable is set, the card device with that path is opened. - If KMSXX_DRIVER env variable is set, the card with the given driver name and index is opened. The format is either "drvname" or "drvname:idx". - If neither env variable is given, the first modeset capable card is opened. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

Add new Card constructor: Card(const std::string& driver, uint32_t idx) which can be used to open Nth card for the given driver.

The format is either "drvname" or "drvname:idx". - If neither env variable is given, open /dev/dri/card0 Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
