This patchset introduces the writeback support to vkms. As a pre-work, the first set of patches separates part of the code inside vkms_crc to a new file named vkms_composer; this change allows that other parts of the vkms take advantage of composing functions. Next, there's a patch that enables the virtual encoder to be compatible with the crtc when we have multiple encoders. The final patch adds the required implementation to enable writeback in the vkms. With this patchset, vkms can successfully pass all the kms_writeback tests from IGT. Note: This patchset depends on Daniel's rework of CRC, see it at https://patchwork.freedesktop.org/series/61737/ Rodrigo Siqueira (5): drm/vkms: Move functions from vkms_crc to vkms_composer drm/vkms: Rename crc_enabled to composer_enabled drm/vkms: Rename vkms_crc_data to vkms_data drm/vkms: Use index instead of 0 in possible crtc drm/vkms: Add support for writeback drivers/gpu/drm/vkms/Makefile | 10 +- drivers/gpu/drm/vkms/vkms_composer.c | 69 +++++++++++ drivers/gpu/drm/vkms/vkms_composer.h | 12 ++ drivers/gpu/drm/vkms/vkms_crc.c | 81 ++----------- drivers/gpu/drm/vkms/vkms_crtc.c | 2 +- drivers/gpu/drm/vkms/vkms_drv.c | 9 +- drivers/gpu/drm/vkms/vkms_drv.h | 18 ++- drivers/gpu/drm/vkms/vkms_output.c | 12 +- drivers/gpu/drm/vkms/vkms_plane.c | 40 +++---- drivers/gpu/drm/vkms/vkms_writeback.c | 166 ++++++++++++++++++++++++++ 10 files changed, 315 insertions(+), 104 deletions(-) create mode 100644 drivers/gpu/drm/vkms/vkms_composer.c create mode 100644 drivers/gpu/drm/vkms/vkms_composer.h create mode 100644 drivers/gpu/drm/vkms/vkms_writeback.c -- 2.21.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
