Follow-up on the v5 [1], things have gotten significantly better in the last 9 months, thanks to the efforts on Bifrost support by the Collabora team (and probably others I'm not aware of). I've been testing this series on a MT8183/kukui device, with a chromeos-5.10 kernel [2], and got basic Chromium OS UI up with mesa 20.3.2 (lots of artifacts though). devfreq is currently not supported, as we'll need: - Clock core support for switching the GPU core clock (see 2/4). - Platform-specific handling of the 2-regulator (see 3/4). Since the latter is easy to detect, patch 3/4 just disables devfreq if the more than one regulator is specified in the compatible matching table. [1] https://patchwork.kernel.org/project/linux-mediatek/cover/20200306041345.259332-1-drinkcat@chromium.org/ [2] https://crrev.com/c/2608070 Changes in v9: - Explain why devfreq needs to be disabled for GPUs with >1 regulators. Changes in v8: - Use DRM_DEV_INFO instead of ERROR Changes in v7: - Fix GPU ID in commit message - Fix GPU ID in commit message Changes in v6: - Rebased, actually tested with recent mesa driver.
