From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx> Hi, This is yet another version of the DRM fences patches. Please refer to the cover letter[1] in a previous version to check for more details. In v7 we now have split most of the out_fences code into prepare_crtc_signaling() and unprepare_crtc_signaling() with improved error handling. More details on the v7 changes are embedded in each commit's message. Robert Foss managed to port Android's drm_hwcomposer to the new HWC2 API and added support to fences. Current patches can be seen here: https://git.collabora.com/cgit/user/robertfoss/drm_hwcomposer.git/log/?h=hwc2_fence_v1 He managed to run AOSP on top of padovan/fences kernel branch with full fence support on qemu/virgl and msm db410c. That means we already have a working open source userspace using the explicit fencing implementation. Also i-g-t testing are available at: https://git.collabora.com/cgit/user/padovan/intel-gpu-tools.git/log/ Please review!
