...step for you, and as suger on top, you no longer have to convince the core drm maintainers that adding a lot of fbdev emulation code is needed. So, I think you actually want to wait for my series to land before adding CLUT support. > Extra questions: > - any plan to update modetest with the DRM_FORMAT_C8 support + gamma > get/set? I don't know that code base at all, but from the glimpse I got when browsing it, it seemed like it was pretty hardwired to non-palettized modes.

We have gamma igts, well for the fancy new atomic color manager stuff.

Update the cirrus driver to follow current best practices. While the driver's hardware is obsolete, the cirrus driver is still one of the go-to modules to learn about writing a DRM driver. So keep it in good shape. Patches 1 to 3 simplify blitting and convert it to the DRM's current helpers. Patches 4 to 8 replace simple-KMS helpers with DRM's regular atomic helpers. The former are

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3 are enough to make the atmel-hlcdc driver do what I need (when patched
