Our goal is to transition to our new DAL display stack. It is the path we are validating internally for both the open and hybrid stacks and will be the only display stack we support going forward with new asics. When we initially released the patches, there were some rough edges and quite a few things were pointed out that need to be fixed. Some are relatively easy to fix, others will take time. Our goal is to make those changes. We'd like to target 4.7 for upstreaming DAL. To that end, I think it would be easier to review and track our progress if I maintained a public DAL branch and send out patches against that branch rather than respinning giant squashed patches every time we fix something. It's much harder to track what progress has been made. DAL is currently at ~400 patches. We previously tried to squash that down into a bunch of larger commits, but I'm not sure that is particularly easy to review. I'm also not sure it's worth spamming the list with 400 patches. I've posted our current DAL tree here for review: https://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.7-wip-dal I can certainly send out the patches if that is preferred. We will be sending out all new patches to the list as the further clean up tasks and new features are implemented. Our goal is to fix the following items in time for 4.7. Additional fixes and re-factoring will continue as we work to address all of the comments and concerns. Tasks to be completed for 4.7: - Remove (malloc/free/sleep/delay/etc.) wrappers for building DAL in userspace (done) - Switch to using Linux i2c subsystem (done) - Switch to using Linux drm aux interface (in progress) - Convert cursors to planes API (in progress) - Switch to native drm EDID fetching (in progress) Tasks post 4.7 (we will attempt to fix these sooner as time permits): - Using common Linux infoframe infrastructure - Migrating to common logging infrastructure - Refactoring DC Current DAL status: - DCE8 Support (Hawaii, Bonaire) - DCE10 Support (Fiji, Tonga) - DCE11 Support (CZ, ST) - DP support (SST, MST, Audio) - HDMI Support - HDMI 2.0 Support (on supported asics) - DVI Support - Full integration with power management - Atomic KMS support - Solid 4K@60 Support Thanks, Alex _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
