This new functionality allows to configure one or more VKMS instances without having to reload the driver using configfs. For more details, have a look to the kernel patchset and the documentation in "vkms.rst" (not merged yet). [1] There was a previous attempt to implement this tests [2] and I kept copyright were required. Massive thank you to Louis Chauvet who is doing a fenomenal work reviewing this (very long) series of patches. Best wishes, José Expósito [1] https://lore.kernel.org/dri-devel/20250307163353.5896-1-jose.exposito89@gmail.com/T/ [2] https://lists.freedesktop.org/archives/igt-dev/2023-September/060717.html Changes in v2: - Applied review comments by Louis Chauvet: - Added missing references to DRIVER_VKMS in drmtest.c - Loading vkms with drm_load_module(DRIVER_VKMS) in igt_fixture - Documented igt_is_mountpoint() - Checked the return value of snprintf() and fprintf() - Removed unnecessary empty items ({ {} }) in items in igt_vkms_config_t - Added new tests testing the valid values for planes, CRTCs and connectors - Remove code duplication generating configfs paths by adding helpers - Using udev instead of drmGetDevices() to find VKMS devices in a new patch "lib/igt_device_scan: Allow to find device by name". This change is required to support the faux bus.
