Subject[git pull] drm v2.6.31 merge (part 1)

Hi Linus,

Please pull the 'drm-linus' branch from
ssh://master.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6.git drm-linus

This contains the Intel tree merge (merged properly I haven't rebased or
touched it), which contains numerous GEM bugfixes + support for a new
chipset. AMD patches for new r600 chipset support. A more flexible drm
debugging system to decrease the firehose effect enabling drm debugging
has, it also contains some paving the way patches for part 2 of the merge.

It also contains one AGP patch for supporting those new chips, and a PNP
patch to add a new interface that intel kms relies on now, all the
signoffs for the pnp code should be correct.

Part 2 will contains an initial radeon KMS driver and the TTM memory
manager, its quite large so I don't want to include it all in this pull.
The initial radeon KMS code enable switch will hide under staging for now
for one driver release while we stabilise it in-tree, its not in a bad
state but its a lot of new code and we'd hate for anyone to fall over it
my accident. Its quite well separated from the old radeon code so
shouldn't fall over too much. I'll send the part 2 pull early next week.

Dave.

drm: Eliminate magic I2C frobbing when reading EDID

This code depends on the underlying I2C adapter using the bit-banging algo,

having it in the general path.

drm: add separate drm debugging levels

Now all the DRM debug info will be reported if the boot option of
"drm.debug=1" is added. Sometimes it is inconvenient to get the debug
info in KMS mode. We will get too much unrelated info.

This will separate several DRM debug levels and the debug level can be used
to print the different debug info. And the debug level is controlled by the
module parameter of drm.debug

In this patch it is divided into four debug levels;
drm_core, drm_driver, drm_kms, drm_mode.

At the same time we can get the different debug info by changing the debug
level. This can be done by adding the module parameter. Of course it can
be changed through the /sys/module/drm/parameters/debug after the system is
booted.

Four debug macro definitions are provided.
DRM_DEBUG(fmt, args...)
DRM_DEBUG_DRIVER(prefix, fmt, args...)
DRM_DEBUG_KMS(prefix, fmt, args...)
DRM_DEBUG_MODE(prefix, fmt, args...)

When the boot option of "drm.debug=4" is added, it will print the debug info
using DRM_DEBUG_KMS macro definition.
When the boot option of "drm.debug=6" is added, it will print the debug info
using DRM_DEBUG_KMS/DRM_DEBUG_DRIVER.

Sometimes we expect to print the value of an array.
For example: SDVO command,
In such case the following four DRM debug macro definitions are added:
DRM_LOG(fmt, args...)
DRM_LOG_DRIVER(fmt, args...)
DRM_LOG_KMS(fmt, args...)
DRM_LOG_MODE(fmt, args...)

drm: don't associate _DRM_DRIVER maps with a master

A driver will use the _DRM_DRIVER map flag to indicate that it wants
to be responsible for removing the map itself, bypassing the DRM's
automagic cleanup code.

Since the multi-master changes this has been broken, resulting in some
drivers having their registers unmapped before it's finished with them.

By sending a broken execbuffer (its length was not suitably aligned) I
triggered an operation upon a freed object. The invalid alignment was
discovered after updating the write_domain on the object but before the
object was placed on the active queue. So during the unwind process
following the error, the now freed object attempts to flush its
non-existent, but outstanding, GPU writes causing this use-after-free.

drm/i915: avoid non-atomic sysrq execution

The sysrq functions are executed in hardirq context, so we shouldn't be
calling sleeping functions from them, like mutex_locks or memory
allocations.

Fix up the i915 sysrq handler to avoid this.

drm/i915: parse VBT general definition block to get the SDVO device info

The general definition block contains the child device tables, which include
the SDVO device info. For example: device slave address, device dvo port,
device type.

We will get the info of SDVO device by parsing the general definition blocks.
Only when a valid slave address is found, it is regarded as the SDVO device.
And the info of DVO port and slave address is recorded.

drm/i915: Change GEM throttling to be 20ms like the comment says.

keithp didn't like the original 20ms plan because a cooperative client could
be starved by an uncooperative client. There may even have been problems
with cooperative clients versus cooperative clients. So keithp changed
throttle to just wait for the second to last seqno emitted by that client.
It worked well, until we started getting more round-trips to the server
due to DRI2 -- the server throttles in BlockHandler, and so if you did more
than one round trip after finishing your frame, you'd end up unintentionally
syncing to the swap.

Fix this by keeping track of the client's requests, so the client can wait
when it has an outstanding request over 20ms old. This should have
non-starving behavior, good behavior in the presence of restarts, and less
waiting. Improves high-settings openarena performance on my GM45 by 50%.

drm/i915: Remove a bad BUG_ON in the fence management code.

This could be triggered by a gtt mapping fault on 965 that decides to
remove the fence from another object that happens to be active currently.
Since the other object doesn't rely on the fence reg for its execution, we
don't wait for it to finish. We'll soon be not waiting on 915 most of the
time as well, so just drop the BUG_ON.
