Jerome's Radeon KMS Short-Term TODO List
Phoronix: Jerome's Radeon KMS Short-Term TODO List
After the earlier X talks today and then Luc's debated Linux graphics driver stack proposal (largely between he and Eric Anholt and Daniel Stone with conflicting views, but at least Intel admitting "there's a subset of users we care about and a subset we don't"), Jerome Glisse began talking about ATI Radeon kernel mode-setting and its current state. While most that read Phoronix regularly know the direction of Radeon KMS support for the coming releases, below is Jerome's short-term TODO list for the ATI kernel support. Coming up in the Radeon DRM for the Linux 2.6.34 kernel (or releases thereafter) is support for un-mappable VRAM, support for Evergreen GPUs (Radeon HD 5000 "R800" series), use of the Linux power management API for better suspend-and-resume support, better DRM power management, HDMI audio for R700/800 graphics processors, and improved GPU lock-up recording. Other plans on the code side include better fence for improved lock-up detection, using union to separate ASIC specific data, and better message prints for multi-GPU configurations. The most common kernel mode-setting problems these days for ATI Radeon customers is coming down to mode detection issues, PLL issues on laptops with Mobility Radeon parts, ACPI/BIOS interaction problems, memory fragmentation, command submission issues, and GPU lock-ups...
So is the DRM "done" for OpenGL on R600,R700 now?
Does this mean that more complete OpenGL support is just down to Mesa these days, and that the remaining DRM work is bug-fixing?
