[PATCH RESEND v2 00/25] drm: fb emulation: Step 1: Create new drm_fb_helper wrapper funcs
DRM drivers using drm_fb_helpers still call some fbdev core functions. This makes the driver depend on CONFIG_FB, resulting in complicated Kconfig options, and preventing us from creating a top level drm config option to enable/disable FBDEV emulation.
Create new drm_fb_helper functions that replace these fbdev functions.
In most cases, the new helper funcs simply wrap around the original fbdev functions. For a few (like framebufer_alloc), we actually do some work that is currently redundant across multiple drivers.
With these patches, the drivers don't call any fbdev functions directly. They are now called through functions in drm_fb_helper.c. We will later create a fbdev emulation config option to stub out the fb helpers.
The only exception is vmwgfx driver. This doesn't use drm_fb_helper. It creates a fb device how a driver in drivers/video/fbdev would. Maybe this needs to be converted to use drm_fb_helpers.
For more info, have a look at the threads: http://lists.freedesktop.org/archives/dri-devel/2015-March/078729.html http://lists.freedesktop.org/archives/dri-devel/2015-March/078975.html

Every drm driver calls framebuffer_alloc, fb_alloc_cmap, unregister_framebuffer, fb_dealloc_cmap and framebuffer_release in order to emulate fbdev support.
Create drm_fb_helper functions that perform the above operations.
This is part of an effort to prevent drm drivers from calling fbdev functions directly. It also removes repetitive code from drivers.
There are some drivers that call alloc_apertures after framebuffer_alloc and some that don't. Make the helper always call alloc_apertures. This would make certain drivers allocate memory for apertures but not use them. Since it's a small amount of memory, it shouldn't be an issue.
v2: - Added kerneldocs - Added a check for non-NULL fb_helper before proceeding. This will make the helpers work when we have a module param for fbdev emulation

Chris Wilson reported on irc that if he builds with I915_FBDEV=n then there's a missing symbol problem here because i915 wants to kick out other framebuffers (well we have to for correctness) even when fbdev emulation is disabled. If you look at i915_dma.c you'll see that the call to remove_conflicting_framebuffers is conditional upon CONFIG_FB and not CONFIG_I915_FBDEV.
I think the proper solution here would be to provide a static inline helper for remove_conflicting_framebuffer itself when CONFIG_FB=n, since a all drivers who call this still want to call this even when fbdev emulation is disabled.
Plan B would be to move this into core drm and make the static inline one selected for CONFIG_FB=n. If you do that then maybe also rename it to drm_remove_conflicting_framebuffer since this really is only tangetial to fbdev emulation.
Anyway current patch unfortunately won't work since we really must remove other framebuffers even in the FB=y, I915_FBDEV=n case. So I dropped it from drm-misc for now. Unfortunately that means all the driver conversions won't apply anymore either :(

I can re-spin the x86 ones and make them stick to the original remove_conflicting_framebuffers call. This way we can at least use the other helpers.

The remove_conflicting_framebuffers calls do_unregister_framebuffer(), which seems to be quite central to fb core, and can't just work without other fb core funcs.
What I don't get is, if legacy fb was never enabled, how did we end up registering fbs in the first place?
Could you briefly explain what these other 'framebuffers' are that remove_conflicting_framebuffers removes? The comments say that they are firmware allocated fbs. I'm not well versed with what happens in desktop graphics.

Following config is the relevant one:
CONFIG_FB=y CONFIG_DRM_I915_FBDEV=n
I.e. core fbdev is enabled and so we might load vesafb or efifb and similar firmware fbdev drivers. But drm/i915 fbdev emulation isn't enabled. Still we absolutely must kick off these firmware fbs in that case. -Daniel

DRM drivers using drm_fb_helpers still call some fbdev core functions. This makes the driver depend on CONFIG_FB, resulting in complicated Kconfig options, and preventing us from creating a top level drm config option to enable/disable FBDEV emulation.
Create new drm_fb_helper functions that replace these fbdev functions.
In most cases, the new helper funcs simply wrap around the original fbdev functions. For a few (like framebufer_alloc), we actually do some work that is currently redundant across multiple drivers.
With these patches, the drivers don't call any fbdev functions directly. They are now called through functions in drm_fb_helper.c. We will later create a fbdev emulation config option to stub out the fb helpers.
The only exception is vmwgfx driver. This doesn't use drm_fb_helper. It creates a fb device how a driver in drivers/video/fbdev would. Maybe this needs to be converted to use drm_fb_helpers.

Every drm driver calls framebuffer_alloc, fb_alloc_cmap, unregister_framebuffer, fb_dealloc_cmap and framebuffer_release in order to emulate fbdev support.
Create drm_fb_helper functions that perform the above operations.
This is part of an effort to prevent drm drivers from calling fbdev functions directly. It also removes repetitive code from drivers.
There are some drivers that call alloc_apertures after framebuffer_alloc and some that don't. Make the helper always call alloc_apertures. This would make certain drivers allocate memory for apertures but not use them. Since it's a small amount of memory, it shouldn't be an issue.
v3: - No changes
v2: - Added kerneldocs - Added a check for non-NULL fb_helper before proceeding. This will make the helpers work when we have a module param for fbdev emulation
