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.

This adds the command stream checker for the RN50, R100 and R200 cards.
It stops any access to 3D registers on RN50, and does checks
on buffer sizes on the r100/r200 cards. It also fixes some texture
sizing checks on r300.

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.]

There are several sources of unnecessary power consumption on Intel
graphics systems. The first is the LVDS clock. TFTs don't suffer from
persistence issues like CRTs, and so we can reduce the LVDS refresh rate
when the screen is idle. It will be automatically upclocked when
userspace triggers graphical activity. Beyond that, we can enable memory
self refresh. This allows the memory to go into a lower power state when
the graphics are idle. Finally, we can drop some clocks on the gpu
itself. All of these things can be reenabled between frames when GPU
activity is triggered, and so there should be no user visible graphical
changes.

In the event that any one of the DAC analog outputs (R,G,B) were driven
at full-scale (white video) or some analog level close to full-scale
voltage, and if the video cable were then disconnected, the analog video
voltage level would exceed the maximum electrical overstress limit of the
native (thin-oxide) transistors thus causing a long-term reliability concern.
The electrical overstress condition occurs in this particular case.
This patch address the IGD EOS (electrical overstress condition) issue.
When the EOS interrupt occurs, OS should disable DAC and then disable EOS,
then the normal hotplug operation follows.
TODO: it appears the normal unplug interrupt is missed as reported by Li Peng,
need more checks here.

Currently SDVO TV only support NTSC-M format. In this patch
we introduce PAL and SECAM formats available and create seting-format
property at init time. When user dynamically chose preferred
format by xrandr command, it will refine all modelines
provided by SDVO device, then instruct SDVO device to execute.
At the same time the property is added for SDVO-TV so that the SDVO-TV mode can be changed
by using xrandr.

For integrated TV there are 3 connector types: S-VIDEO, Composite and
Component(YprPb). Those tv formats whose component flag is true should
be assigned to Component connector, others are for S-VIDEO and Composite.
The patch intends to find appropriate tv format for each connector.
In such case it will return the correct modeline to user space. Otherwise
it will return the incorrect modeline when S-video/composite is connected.

Some i915/i945 platforms have a fairly high memory latency in certain
situations, so increase our constant a bit to avoid FIFO underruns.
The effect should be positive on other platforms as well; we'll have a
bit more insurance against a busy memory subsystem due to the extra
FIFO entries.
Fixes fdo bug #23368. Needed for 2.6.31.

Commit log for commit 517d3cc15b36392e518abab6bacbb72089658313
("[libata] ata_piix: Enable parallel scan") says:
This patch turns on parallel scanning for the ata_piix driver.
This driver is used on most netbooks (no AHCI for cheap storage it seems).
The scan is the dominating time factor in the kernel boot for these
devices; with this flag it gets cut in half for the device I used
for testing (eeepc).
Alan took a look at the driver source and concluded that it ought to be safe
to do for this driver. Alan has also checked with the hardware team.
and it is all true but once we put all things together additional
constraints for PATA controllers show up (some hardware registers
have per-host not per-port atomicity) and we risk misprogramming
the controller.
I used the following test to check whether the issue is real:
@@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_
(timings[pio][1] << 8);
}
pci_write_config_word(dev, master_port, master_data);
- if (is_slave)
+ if (is_slave) {
+ if (ap->port_no == 0) {
+ u8 tmp = slave_data;
+
+ while (slave_data == tmp) {
+ pci_read_config_byte(dev, slave_port, &tmp);
+ msleep(50);
+ }
+
+ dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan "
+ "race detected\n");
+ }
pci_write_config_byte(dev, slave_port, slave_data);
+ }
/* Ensure the UDMA bit is off - it will be turned back on if
UDMA is selected */
and it indeed triggered the error message.
Lets fix all such races by adding an extra locking to ->set_piomode
and ->set_dmamode methods for PATA controllers.
[ Alan: would be better to take the host lock in libata-core for these
cases so that we fix all the adapters in one swoop. "Looks fine as a
temproary quickfix tho" ]
