It seems some of those IGP dislike non dma32 page despite what documentation says. Fix regression since we allowed non dma32 pages. It seems it only affect some revision of those IGP chips as we don't know which one just force dma32 for all of them. https://bugzilla.redhat.com/show_bug.cgi?id=785375 Signed-off-by: Jerome Glisse Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman --- diff --git a/drivers/gpu/drm/radeon/radeon_device.c b/drivers/gpu/drm/radeon/radeon_device.c index 5992502a3448..de5e0b51dc63 100644 --- a/drivers/gpu/drm/radeon/radeon_device.c +++ b/drivers/gpu/drm/radeon/radeon_device.c @@ -772,7 +772,7 @@ int radeon_device_init(struct radeon_device *rdev, if (rdev->flags & RADEON_IS_AGP) rdev->need_dma32 = true; if ((rdev->flags & RADEON_IS_PCI) && - (rdev->family < CHIP_RS400)) + (rdev->family <= CHIP_RS740)) rdev->need_dma32 = true; dma_bits = rdev->need_dma32 ? 32 : 40;
