When the output device is LVDS, maybe the pixel clock of adjusted_mode will be
less than that in mode. In such case it will set the incorrect multipler factor
in DPLL_MD register.
So the dpll_md_reg will be reset when the output type is non-SDVO

When the sdvo device is detected as SDVO-LVDS, we will check whether the

If it is supported, we will add the brightness property and then brightness

When the sdvo device is detected as SDVO-TV, we will check whether the
sepecific picture enhancement is supported. If it is supported, we will
add the corresponnding property for SDVO-TV. We will add the following
property for the SDVO-TV enhancements if they are supported:
 * Contrast/Brightness/Saturation/Hue.
 * left/right/top/bottom margin: This is implemented by using the
   horizontal/vertical overscan enhancements. When the overscan
   enhancements are supported, the above properties will be added. This is
   to be compatible with what we have done in integrated-TV.
 * horizontal pos/vertical pos.

Otherwise, some other userland writing into its buffer may race to land
writes either after the CPU thinks it's got a coherent view, or after its

When an output was disconnected, its mode list would remain.  If you later
plugged into a sink with no EDID (projector, etc), you'd inherit the mode
list from the old sink, which is not what you want.

This adds the r600 KMS + CS support to the Linux kernel.

The r600 TTM support is quite basic and still needs more
work esp around using interrupts, but the polled fencing
should work okay for now.

Also currently TTM is using memcpy to do VRAM moves,
the code is here to use a 3D blit to do this, but
isn't fully debugged yet.

When we need to add the standard timing mode, we will firstly check whether it
can be found in DMT table by comparing the hdisplay/vdisplay/vfresh_rate.
If it can't be found, then we will use the cvt/gtf to add the required mode.
If it can be found, it will be returned.

At the same time the function of drm_mode_vrefresh is also fixed. It will
return the result of actual refresh_rate plus 0.5.
For example:
When the calculated value is 84.9, then the fresh_rate is 85.
When the calculated value is 70.02, then the fresh_rate is 70.

When we add a standard timing mode in UMS, we will first check whether it can
be found in default mode table. If it can't be found, then we will use cvt/gtf
to add the standard timing mode.
Add the default mode table so that we can check whether the given mode
can be found in the default mode table as what we have done in UMS mode.

If the status of one output device is connected but there is no EDID, it will
have no correct mode. In such case we can add some default modes for it. Of
course we only add the modes in the default modes list that visible part is not
greater than 1024x768.

The default mode is autogenerated from the DMT spec. And it is copied from
xserver/hw/xfree86/modes/xf86EdidModes.c. But the mode with reduced blank
feature is removed.

According to the docs, the ringbuffer is not allowed to wrap in the middle
of an instruction.

G45 PRM, Vol 1b, p101:
  While the “free space” wrap may allow commands to be wrapped around the
  end of the Ring Buffer, the wrap should only occur between commands.
  Padding (with NOP) may be required to follow this restriction.

Do as commanded.

[Having seen bug reports where there is evidence of split commands, but
apparently the GPU has continued on merrily before a bizarre and untimely
death, this may or may not fix a few random hangs.]
