drm/udl: limit modes to the sku pixel limits.

2012-10-02T17:40:03+00:00

commit 3a75885848996baab5276ff37ebf7295c3c753f0 upstream.

Otherwise when X starts we commonly get a black screen scanning
out nothing, its wierd dpms on/off from userspace brings it back,

With this on F18, multi-seat works again with my 1920x1200 monitor
which is above the sku limit for the device I have.

drm/udl: Make sure to get correct endian keys from vendor descriptor

2012-06-25T06:43:12+00:00

This is a port of
commit b49f184b640dcfab7ede394cf2a1ff4fe3d154f5
Author: Ben Collins 
from udlfb to udl kms driver.

The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen
on big-endian CPUs where the DL chips's max mode was smaller than the
monitor's native mode.

drm/udl: unlock before returning in udl_gem_mmap()

2012-05-29T10:02:50+00:00

If we hit an error here, then we should unlock and unreference obj
before returning.

udl: add prime fd->handle support.

2012-05-23T09:46:05+00:00

udl can only be used as an output offload so doesn't need to support
handle->fd direction.

drm: Constify drm_mode_config_funcs pointer

2012-05-22T09:35:07+00:00

The DRM mode config functions structure declared by drivers and pointed
to by the drm_mode_config funcs field is never modified. Make it a const
pointer.

drm: Constify gem_vm_ops pointer

2012-05-22T09:34:53+00:00

The GEM vm operations structure is passed to the VM core that stores it
in a const field. There vm operations structures can thus be const in
DRM as well.

mm, drm/udl: fixup vma flags on mmap

2012-04-02T10:08:17+00:00

There should be VM_MIXEDMAP, not VM_PFNMAP, because udl_gem_fault() inserts
pages via vm_insert_page(). Other drm/gem drivers already do this.
