2022-07-25T21:17:28Z

[Why&How] Preparation to enable run time initialization of register offsets to add dc_context to the link_enc_create callback. This is needed to get the dc_ctx handle where register offset initialization routine is called.

drm/amd/display: Enable fp16 also on DCE-8/10/11.

2021-01-05T16:35:22Z

The hw supports fp16, this is not only useful for HDR, but also for standard dynamic range displays, because it allows to get more precise color reproduction with about 11 - 12 bpc linear precision in the unorm range 0.0 - 1.0. Working fp16 scanout+display (and HDR over HDMI) was verified on a DCE-8 asic, so i assume that the more recent DCE-10/11 will work equally well, now that format-specific plane scaling constraints are properly enforced, e.g., the inability of fp16 to scale on older hw like DCE-8 to DCE-11.

This request: each acquired_i2c_engine setup the i2c speed needed and sets the I2c engine for HDCP use at release_engine. This covers SW using HW i2c engine and HDCP using HW i2c engine. for dmcu using HW i2c engine, needs add similar logic in dmcu fw.
