In reality gma500 is igpu and never shipped with anything discrete, so there should not be any difference. v2: Unfortunately the framebuffer sits outside of the pci bars for gma500, and so only using the pci helpers won't be enough. Otoh if we only use non-pci helper, then we don't get the vga handling, and subsequent refactoring to untangle these special cases won't work. It's not pretty, but the simplest fix (since gma500 really is the only quirky pci driver like this we have) is to just have both calls. v4: - fix Daniel's S-o-b address Signed-off-by: Daniel Vetter Cc: Patrik Jakobsson Cc: Thomas Zimmermann Cc: Javier Martinez Canillas --- drivers/gpu/drm/gma500/psb_drv.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/gma500/psb_drv.c b/drivers/gpu/drm/gma500/psb_drv.c index 2ce96b1b9c74..f1e0eed8fea4 100644 --- a/drivers/gpu/drm/gma500/psb_drv.c +++ b/drivers/gpu/drm/gma500/psb_drv.c @@ -422,12 +422,17 @@ static int psb_pci_probe(struct pci_dev *pdev, const struct pci_device_id *ent) /* * We cannot yet easily find the framebuffer's location in memory.
