2025-12-18perf: Pass parameters by const reference to avoid copiesTomi Valkeinen
Fix cppcheck performance warnings by passing function parameters by const reference instead of by value, preventing unnecessary copies: - string parameters in open_device_by_path() - set<Connector*> parameters in connector finder functions - vector parameter in FlipState constructor - range variable in kmscapture loop These changes improve performance by avoiding object copies while maintaining the same functionality.
2025-12-18fix: Replace C-style casts with C++ static/reinterpret castsTomi Valkeinen
C-style casts should be replaced with appropriate C++ cast operators for better type safety and code clarity. This change fixes cppcheck style warnings about C-style pointer casting by using: - static_cast for simple pointer type conversions - reinterpret_cast for memory buffer pointer arithmetic The changes maintain identical functionality while following modern C++ best practices for explicit casting.

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>

2024-12-09Implement native visual matchingKaido Kert
Implement matching GBM buffer format to EGL NATIVE_VISUAL_ID. eglChooseConfig cannot match on NATIVE_VISUAL_ID, but GBM/EGL requires matching formats. Similar logic is implemented in kmscube code in match_config_to_visual. X11, Wayland and Null cube demos remain unchanged. Tested on Raspi-4 and VirtualBox/Ubuntu

2023-11-15testpat: Fix memory mapping in threaded drawingLaurent Pinchart
The IFramebuffer::map() function is not thread-safe, which is why the threaded implementation of draw_test_pattern_impl() maps all planes before starting to draw. A typo slipped in the code, resulting in only plane 0 being mapped. This didn't result in an immediate segfault, as drawing operations in the worker threads map the remaining planes. However, due to the implementation of DumbFramebuffer::map(), this can result in the same plane being mapped multiple times, with only one of the mapping recorded in the mapping cache. The other mappings are then leaked, leading not only to extra memory consumption, but also to the DRM device never being released even after the destruction of the Card object. Fix this.

2023-11-07kmstest: Don't fail if setting crtc inactive and disabling the planes failsDave Stevenson
Many simple DRM devices (eg SPI) don't support disabling the primary plane when the CRTC is enabled (which is different from the ACTIVE flag from being cleared). This is enforced by the kernel in drm_atomic_helper_check_crtc_primary_plane. Do not exit if that commit fails. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
