From 386516744ba45d50f42c6999151cc210cb4f96e4 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 30 Mar 2010 05:34:13 +0000 Subject: drm/fb: fix fbdev object model + cleanup properly. The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work. This patch a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs. b) migrated all the fb helper functions out of the crtc helper file into the fb helper file. c) pushed the fb probing/hotplug control into the driver d) makes the surface sizes into a structure for ease of passing This changes the intel/radeon/nouveau drivers to use the new helper.

It also removes the untype void* that was in the connector struct to support this. All connectors are added to the fbdev now but this could be changed in the future.

This hooks set_par to hopefully do the changes once X hands control to fbdev. This also adds the nouveau/intel hotplug support.

It removes the drm_fb_helper_setcolreg function. The reason is that fb_setcolreg is only used in the case where fb_setcmap is called and no fb_ops->fb_setcmap is used. In the drm case we always need a fb_setcmap hook to handle multiple crtcs so we don't need a fb_setcolreg hook. Please apply.
