Summary: The addition of the test infrastructure is motivated by the regressions caused by adding mode switching and transformation support. A contributing factor to these regression is the fact that the DRM platform does not have any tests. It is difficult to test this code as it needs to work with hardware, thus we cannot use the real DRM library. Instead we need to use mocking. This change sets up some first basic tests with the help of a mockDrm library. In order to better test the code as units the Drm classes are slightly refactored. Most importantly the dependency to DrmBackend is removed wherever possible and replaced by a simple int fd which is mostly the only element used by the classes. This first test introduces basic testing of a DrmObject. It is intended to extend this to at least also test DrmPlane as a central piece of our Drm platform plugin. This will also extend the tests of DrmObject. Reviewers: #kwin, #plasma Subscribers: plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D8776

# FindLibdrm
|
|
# -------
|
|
#
|
|
# Try to find libdrm on a Unix system.
|
|
#
|
|
# This will define the following variables:
|
|
#
|
|
# ``Libdrm_FOUND``
|
|
# True if (the requested version of) libdrm is available
|
|
# ``Libdrm_VERSION``
|
|
# The version of libdrm
|
|
# ``Libdrm_LIBRARIES``
|
|
# This can be passed to target_link_libraries() instead of the ``Libdrm::Libdrm``
|
|
# target
|
|
# ``Libdrm_INCLUDE_DIRS``
|
|
# This should be passed to target_include_directories() if the target is not
|
|
# used for linking
|
|
# ``Libdrm_DEFINITIONS``
|
|
# This should be passed to target_compile_options() if the target is not
|
|
# used for linking
|
|
#
|
|
# If ``Libdrm_FOUND`` is TRUE, it will also define the following imported target:
|
|
#
|
|
# ``Libdrm::Libdrm``
|
|
# The libdrm library
|
|
#
|
|
# In general we recommend using the imported target, as it is easier to use.
|
|
# Bear in mind, however, that if the target is in the link interface of an
|
|
# exported library, it must be made available by the package config file.
