The Weston project use VKMS when running its test suite in CI, and we have now uses cases which would need to ability to set-up the outputs DPMS/state individually, rather than globally -- which would affect all outputs. This an attempt on fixing that by giving the possibility to create more than one pipe, and thus allowing to run tests that could exercise code paths in the compositor related to management of outputs. v2: - Replace 'outputs' with 'pipes' as to use the proper terminology (Thomas Zimmermann, Maíra Canal) - Fixed passing wrong possible_crtc bitmask when initializing the write back connector which address kms_writeback failure (Maíra Canal) - Add a feat. note about moving overlay planes between CRTCs (Melissa Wen) Marius Vlad (3): vkms: Pass the correct bitmask for possible crtcs vkms: Add support for multiple pipes Documentation/gpu/vkms.rst: Added a note about plane migration Documentation/gpu/vkms.rst | 5 +++-- drivers/gpu/drm/vkms/vkms_crtc.c | 3 +-- drivers/gpu/drm/vkms/vkms_drv.c | 27 ++++++++++++++++++++++----- drivers/gpu/drm/vkms/vkms_drv.h | 11 ++++++++--- drivers/gpu/drm/vkms/vkms_output.c | 7 +++---- drivers/gpu/drm/vkms/vkms_writeback.c | 24 ++++++++++++------------ 6 files changed, 49 insertions(+), 28 deletions(-) -- 2.39.2
