similar to: [PATCH v3] drm/cirrus: flip default from 24bpp to 16bpp

The problem with 24bpp is that it is a rather unusual depth these days, cirrus is pretty much the only relevant device still using that, and it is a endless source of issues. Wayland doesn't support it at all. Bugs in Xorg keep showing up. Typically either 32bpp or 16bpp are used. Using 32bpp would limit the resolution to 800x600 due to hardware constrains. So lets go with 16bpp. Also

Time to kill some bad sample code people are copying from ;) This is a complete rewrite of the cirrus driver. The cirrus_mode_set() function is pretty much the only function which is carried over largely unmodified. Everything else is upside down. It is a single monster patch. But given that it does some pretty fundamental changes to the drivers workflow and also reduces the code size by

cirrus can handle 1024x768 (and slightly higher) with 24bpp depth. cirrus can handle up to 800x600 with 32bpp. The problem with 24bpp is that it is a rather unusual depth these days, cirrus is pretty much the only relevant device still using that, and it is a endless source of issues. Wayland doesn't support it at all. Bugs in Xorg keep showing up. So using 32bpp by default is the better

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 through 5 are enough to make the atmel-hlcdc driver do what I need. The rest

This patch replaces mgag200's framebuffer console with DRM's generic implememtation. All respective code is being removed from the driver. The console is set up with a shadow buffer. The actual buffer object is not permanently pinned in video ram, but just another buffer object that the driver moves in and out of vram as necessary. The driver's function mga_crtc_do_set_base() used to
