FakeDRM - userspace DRM emulation library This is FakeDRM, a userspace library providing userspace emulation of Linux Direct Rendering Manager kernel interfaces. The library provides wrappers for system calls (typically provided by libc) to catch relevant operations on DRM devices and emulate them in userspace. Compiling --------- libdrm uses CMake as its build system of choice and follows the typical procedures of installation for projects using this build system. The first step is to create makefiles by running CMake: cmake . Next step is to build the library: make and once make finishes successfully, install the package using make install Running -------- FakeDRM library consists of a binary file called libfakedrm.so, which needs to be preloaded for any application which should have kernel DRM interfaces emulated in userspace: export LD_PRELOAD=/usr/lib/libfakedrm.so ./testapp To support various extensions provided by real kernel DRM drivers, an environment variable FAKEDRM_DRIVER is used to select which driver should be emulated. Currently supported drivers: dummy - dummy FakeDRM driver, providing only generic functionality exynos - Exynos DRM (Samsung SoC DRM),
