2026-05-11utils: Add a dump_framebuffer() methodLaurent Pinchart
Add a new method to write the contents of a framebuffer to a file descriptor. This can be used to capture frames from writeback connectors. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2026-05-08kmstest: Use pixpat vbar for the moving flip barTomi Valkeinen
Replace the hand-rolled draw_color_bar call in FlipState::draw_bar with pixpat's "vbar" pattern via a new draw_vbar_pattern helper in kms++util. The pattern fills the full buffer, so the old_xpos bookkeeping for clearing the previous bar is no longer needed.
2026-05-08kms++util: Replace test-pattern generator with pixpatTomi Valkeinen
Switch draw_test_pattern() to call libpixpat (linked statically into libkms++util.so) instead of the in-tree pattern generator. Pixpat covers every pattern (kmstest, smpte, solid colors) and every pixel format the previous generator handled, so behavior is unchanged for all callers. Drop the now-unused machinery: conv.h and conv-*.h template writers, color16.h (RGB16/YUV16 plus conversions), the *_old / _single / _multi declarations that had no definitions or callers, and the c_draw_test_pattern C ABI which had no callers anywhere in the tree. RecStandard and ColorRange move from color16.h directly into kms++util.h, since they are still part of the public TestPatternOptions struct.
2025-09-08utils: c_draw_test_pattern() takes format name, not fourccTomi Valkeinen
We can generate test patterns for pixel formats not in DRM, so we can't take DRM fourcc as a parameter for c_draw_test_pattern(). Switch it to format name instead. This is a ABI change, but it is marked as super experimental. Also, it feels a bit odd to add non-DRM format handling to kms++. But it feels a bit pointless to split the testpat generation to a separate library. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>

2025-04-17color16: Fix RGB-to-YUVTomi Valkeinen
The calculation was not right, producing bad values. Fix it, and this time actually test the output... Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
2025-03-26kms++util: Add draw_test_pattern() with C ABITomi Valkeinen
Add a draw_test_pattern for C ABI (i.e. not C++). This function can be easily called from Python with ctypes, without any kind of bindings. Experimental, ABI can change. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>

2020-05-15resmgr: add release() methodsMatt Hoosier
This makes the ResourceManager class much more functional for uses where the set of resources used to scan out a scene changes from frame to frame. The atomic modesetting API discipline requires a brute-force search to find a compatible pairing of planes/etc, and being able to reserve bits incrementally is much simpler than throwing out the entire resourcemanager and make a new one each time a resource reserved in a tentative attempt to probe its compatibility with an test-mode atomic commit, turns out not to pan out.

2017-10-03Rework framebuffer classesTomi Valkeinen
Drop (I)MappedFramebuffer, as it doesn't really provide any value, and have most of the methods be present in IFramebuffer with default exception throwing implementation. This gives us simpler way to use the framebuffers, as almost always we can just use a pointer to IFramebuffer.
