I tried looking around, and I didn't find any non-pci vga-compatible controllers for x86 (since that's the only platform where we had this until a few patches ago), where a driver participating in the aperture claim dance would interfere. - I also don't expect that any future bus anytime soon will not just look like pci towards the OS, that's been the case for like 25+ years by now for practically everything (even non non-x86). - Also it's a bit funny if we have one part of the vga removal in the pci function, and the other in the generic one. v2: Rebase. v4: - fix Daniel's S-o-b address Signed-off-by: Daniel Vetter Cc: Thomas Zimmermann Cc: Javier Martinez Canillas Cc: Helge Deller Cc: linux-fbdev@vger.kernel.org Reviewed-by: Javier Martinez Canillas --- drivers/video/aperture.c | 15 +++++++-------- 1 file changed, 7 insertions(+), 8 deletions(-) diff --git a/drivers/video/aperture.c b/drivers/video/aperture.c index 26bdba6b2725..3aad10ab620e 100644 --- a/drivers/video/aperture.c +++ b/drivers/video/aperture.c @@ -298,14 +298,6 @@ int aperture_remove_conflicting_devices(resource_size_t base, resource_size_t si aperture_detach_devices(base, size); - /* - * If this is the primary adapter, there could be a VGA device - * that consumes the VGA framebuffer I/O range.
