      drm/fb-helper: don't call remove_conflicting_framebuffers for FB=m && DRM=y · 749cc6f7
      由 Arnd Bergmann 提交于 
      When CONFIG_DRM_KMS_FB_HELPER is disabled, we can have a configuration
in which some DRM drivers are built-in, but the framebuffer core is a
loadable module. This results in a link error, such as:

drivers/gpu/drm/radeon/radeon.o: In function `radeon_pci_probe':
radeon_kfd.c:(.text.radeon_pci_probe+0xbc): undefined reference to `remove_conflicting_framebuffers'
drivers/gpu/drm/amd/amdgpu/amdgpu.o: In function `amdgpu_pci_probe':
amdgpu_mn.c:(.text.amdgpu_pci_probe+0xa8): undefined reference to `remove_conflicting_framebuffers'
drivers/gpu/drm/mgag200/mgag200.o: In function `mga_vram_init':
mgag200_ttm.c:(.text.mga_vram_init+0xa8): undefined reference to `remove_conflicting_framebuffers'
drivers/gpu/drm/mgag200/mgag200.o: In function `mga_pci_probe':
mgag200_ttm.c:(.text.mga_pci_probe+0x88): undefined reference to `remove_conflicting_framebuffers'
Makefile:969: recipe for target 'vmlinux' failed

This changes the compile-time check to IS_REACHABLE, which means we end up
not calling remove_conflicting_framebuffers() in the configuration, which
seems good enough, as we know that no framebuffer driver is loaded by the
time that the built-in DRM driver calls remove_conflicting_framebuffers.

We could alternatively avoid the link error by forcing CONFIG_FB to not
be a module in this case, but that wouldn't change anything at runtime,
and just make the already convoluted set of dependencies worse here.

I could not find out what happens if the fbdev driver gets loaded as
a module after the DRM driver is already initialized, but that is a case
that can happen with or without this patch.

      drm: Add top level Kconfig option for DRM fbdev emulation · a03fdcb1
      由 Archit Taneja 提交于 
      Legacy fbdev emulation support via DRM is achieved through KMS FB helpers.
Most modesetting drivers enable provide fbdev emulation by default by
selecting KMS FB helpers. A few provide a separate Kconfig option for the
user to enable or disbale fbdev emulation.

Enabling fbdev emulation is finally a distro-level decision. Having a top
level Kconfig option for fbdev emulation helps by providing a uniform way
to enable/disable fbdev emulation for any modesetting driver. It also lets
us remove unnecessary driver specific Kconfig options that causes bloat.

With a top level Kconfig in place, we can stub out the fb helper functions
when not needed without breaking functionality. Having stub functions also
prevents drivers to require wrapping fb helper function calls with #ifdefs.

DRM_FBDEV_EMULATION defaults to y since many drivers enable fbdev
emulation by default and majority of distributions expect the fbdev
interface in the kernel.

      drm/fb_helper: Add drm_fb_helper functions to manage fb_info creation · b8017d6c
      由 Archit Taneja 提交于 
      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.

      drm: Perform cmdline mode parsing during connector initialisation · eaf99c74
      由 Chris Wilson 提交于 
      i915.ko has a custom fbdev initialisation routine that aims to preserve
the current mode set by the BIOS, unless overruled by the user. The
user's wishes are determined by what, if any, mode is specified on the
command line (via the video= parameter). However, that command line mode
is first parsed by drm_fb_helper_initial_config() which is called after
i915.ko's custom initial_config() as a fallback method. So in order for
us to honour it, we need to move the cmdline parser earlier. If we
perform the connector cmdline parsing as soon as we initialise the
connector, that cmdline mode and forced status is then available even if
the fbdev helper is not compiled in or never called.

We also then expose the cmdline user mode in the connector mode lists.

v2: Rebase after connector->name upheaval.

v3: Adapt mga200 to look for the cmdline mode in the new place. Nicely
simplifies things while at that.

v4: Fix checkpatch.

v5: Select FB_CMDLINE to adapt to the changed fbdev patch.
