From 7450cd235b45d43ee6f3c235f89e92623458175d Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 6 Apr 2023 15:21:04 +0200 Subject: [PATCH] video/aperture: Only kick vgacon when the pdev is decoding vga Otherwise it's a bit silly, and we might throw out the driver for the screen the user is actually looking at. I haven't found a bug report for this case yet, but we did get bug reports for the analog case where we're throwing out the efifb driver. v2: Flip the check around to make it clear it's a special case for kicking out the vgacon driver only (Thomas) v4: - fixes to commit message - fix Daniel's S-o-b address v5: - add back an S-o-b tag with Daniel's Intel address Link: https://bugzilla.kernel.org/show_bug.cgi?id=216303 Signed-off-by: Daniel Vetter Signed-off-by: Daniel Vetter Signed-off-by: Thomas Zimmermann Cc: Thomas Zimmermann Cc: Javier Martinez Canillas Cc: Helge Deller Cc: linux-fbdev@vger.kernel.org Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230406132109.32050-5-tzimmermann@suse.de --- drivers/video/aperture.c | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) diff --git a/drivers/video/aperture.c b/drivers/video/aperture.c index c56553d86fe77..b85163e843f30 100644 --- a/drivers/video/aperture.c +++ b/drivers/video/aperture.c @@ -342,13 +342,15 @@ int aperture_remove_conflicting_pci_devices(struct pci_dev *pdev, const char *na return ret; } - /* - * WARNING: Apparently we must kick fbdev drivers before vgacon, - * otherwise the vga fbdev driver falls over. - */ - ret = vga_remove_vgacon(pdev); - if (ret) - return ret; + if (primary) { + /* + * WARNING: Apparently we must kick fbdev drivers before vgacon, + * otherwise the vga fbdev driver falls over. + */ + ret = vga_remove_vgacon(pdev); + if (ret) + return ret; + } return 0; -- 2.30.2
