See also commit 1d38fe6ee6a8 ("PCI/VGA: Move vgaarb to drivers/pci") This should not result in any functional change, and the non-x86 multi-gpu pci systems are probably rare enough to not matter (I don't know of any tbh). But it's a nice cleanup, so let's do it. There's been a few questions on previous iterations on dri-devel and irc: - fb_is_primary_device() seems to be yet another implementation of this theme, and at least on x86 it checks for both vga_default_device OR rom shadowing. There shouldn't ever be a case where rom shadowing gives any additional hints about the boot vga device, but if there is then the default vga selection in vgaarb should probably be fixed. And not special-case checks replicated all over. - Thomas also brought up that on most !x86 systems fb_is_primary_device() returns 0, except on sparc/parisc. But these 2 special cases are about platform specific devices and not pci, so shouldn't have any interactions. - Furthermore fb_is_primary_device() is a bit a red herring since it's only used to select the right fbdev driver for fbcon, and not for the fw handover dance which the aperture helpers handle. At least for x86 we might want to look into unifying them, but that's a separate thing. v2: Extend commit message trying to summarize various discussions. v4: - make the test for the primary device easier to read (Javier) - fix commit message style (i.e., commit 1234 ("...")) - 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 Cc: Bjorn Helgaas Cc: linux-pci@vger.kernel.org Reviewed-by: Javier Martinez Canillas --- drivers/video/aperture.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/drivers/video/aperture.c b/drivers/video/aperture.c index 41e77de1ea82..d0eccc4ed60b 100644 --- a/drivers/video/aperture.c +++ b/drivers/video/aperture.c @@ -328,9 +328,8 @@ int aperture_remove_conflicting_pci_devices(struct pci_dev *pdev, const char *na resource_size_t base, size;

Also I'm about to add a different boolean argument, so it's better to keep the confusion down to the absolute minimum. v2: Since the hypervfb patch got droppped (it's only a pci device for gen1 vm, not for gen2) there is one leftover user in an actual driver left to touch. v4: - fixes to commit message - 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 Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: "K.
