Subject: [PATCH v4 0/9] video/aperture: Ignore firmware framebuffers with non-primary devices
Date: Thu,  6 Apr 2023 10:32:31 +0200	[thread overview]
Message-ID: <20230406083240.14031-1-tzimmermann@suse.de> (raw)

Only remove sysfb and VGA devices for primary graphics devices. The
PCI helper for aperture ownership now detects primary devices. Resolves
bug reports about lost framebuffer consoles on systems with multiple
graphics cards.

The series picks up Daniel's patchset at v3 from [1] and cleans up a few
minor things. There's another patch on top that clarifys gma500's
special case.

v4:
	* add gma500 patch on top of v3
	* fix Daniel's S-o-b address
	* fix various typos in the commit messages

  drm/gma500: Use drm_aperture_remove_conflicting_pci_framebuffers
  video/aperture: use generic code to figure out the vga default device
  drm/aperture: Remove primary argument
  video/aperture: Only kick vgacon when the pdev is decoding vga
  video/aperture: Move vga handling to pci function
  video/aperture: Drop primary argument
  video/aperture: Only remove sysfb on the default vga pci device
  fbdev: Simplify fb_is_primary_device for x86

Thomas Zimmermann (1):
  video/aperture: Provide a VGA helper for gma500 and internal use
