introduce SIZE_MAX

2012-06-01T00:49:26+00:00

ULONG_MAX is often used to check for integer overflow when calculating
allocation size.  While ULONG_MAX happens to work on most systems, there
is no guarantee that `size_t' must be the same size as `long'.

This patch introduces SIZE_MAX, the maximum value of `size_t', to improve
portability and readability for allocation size validation.

ttm: add prime sharing support to TTM (v2)

2012-05-23T09:46:27+00:00

This adds the ability for ttm common code to take an SG table
and use it as the backing for a slave TTM object.

The drivers can then populate their GTT tables using the SG object.

v2: make sure to setup VM for sg bos as well.

drm/prime: introduce sg->pages/addr arrays helper

2012-05-23T09:45:57+00:00

the ttm drivers need this currently, in order to get fault handling
working and efficient.

It also allows addrs to be NULL for devices like udl.

drm: add plane properties

2012-05-22T09:54:30+00:00

The omapdrm driver uses this for setting per-overlay rotation.  It
is likely also useful for setting YUV->RGB colorspace conversion
matrix, etc.

drm: add bitmask property type

2012-05-22T09:54:16+00:00

A bitmask property is similar to an enum.  The enum value is a bit
position (0-63), and valid property values consist of a mask of
zero or more of (1 << enum_val[n]).

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.

drm/dp: Add DPCD defines for register 0x007

2012-05-22T09:18:36+00:00

Low four bits are downstream port count.  High bit indicates peer OUI
support.  OUI matching will allow us to do additional per-sink handling
for things like DP->VGA bandwidth limits or (hopefully) the iMac-as-
display hack.
