This is the V3 version of a series that introduces the writeback support to vkms. As a result of the previous review, this patchset can be seen in three parts: make vkms able to support multiple connector, pre-work for vkms, and the vkms implementation. Follows the details: * First part: The first patch of this series is a fix that enables vkms to accept new connectors, such as writeback connector. * Second part: The second part of this patchset starts on patch 02 and finish on patch 04; basically it is a pre-work that aims to make vkms composer operations a little bit more generic. These patches update the CRC files and function to make it work as a composer; it also centralizes the vkms framebuffer operations. Additionally, these changes enable the composer to use the writeback framebuffer instead of creating a copy. * Third part: The final patch enables the support for writeback in vkms. With this patchset, vkms can successfully pass all the kms_writeback tests from IGT. Note: Most of the changes in the V3 was suggested by Daniel Vetter as can be seen at the link https://patchwork.freedesktop.org/patch/311844/?series=61738&rev=2 Note: This patchset depends on Daniel's rework of CRC, see it at https://patchwork.freedesktop.org/series/61737/ Rodrigo Siqueira (5): drm/vkms: Avoid assigning 0 for possible_crtc drm/vkms: Rename vkms_crc.c into vkms_composer.c drm/vkms: Decouple crc operations from composer drm/vkms: Compute CRC without change input data drm/vkms: Add support for writeback drivers/gpu/drm/vkms/Makefile | 9 +- .../drm/vkms/{vkms_crc.c => vkms_composer.c} | 174 ++++++++++-------- drivers/gpu/drm/vkms/vkms_crtc.c | 30 +-- drivers/gpu/drm/vkms/vkms_drv.c | 10 +- drivers/gpu/drm/vkms/vkms_drv.h | 40 ++-- drivers/gpu/drm/vkms/vkms_output.c | 16 +- drivers/gpu/drm/vkms/vkms_plane.c | 40 ++-- drivers/gpu/drm/vkms/vkms_writeback.c | 141 ++++++++++++++ 8 files changed, 331 insertions(+), 129 deletions(-) rename drivers/gpu/drm/vkms/{vkms_crc.c => vkms_composer.c} (51%) create mode 100644 drivers/gpu/drm/vkms/vkms_writeback.c -- 2.21.0 -- Rodrigo Siqueira https://siqueira.tech _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
