5a5a0c64a9 drm/i915: implement fastpath for overlay flip waiting
As long as the gpu can keep up, neither the cpu (waiting for gpu)
nore the gpu (waiting for vblank to do an overlay flip) stalls.

240a2d12df drm/i915: fully switch off overlay when not in use
Now that the cache flushing of the memory based overlay regs works,
we can safely switch off the overlay. Beforehand it was only disabled
(like in userspace).

02e792fbaa drm/i915: implement drmmode overlay support v4
This implements intel overlay support for kms via a device-specific
ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on
dri-devel). We've reached the conclusion that such an infrastructure
only makes sense when multiple kms overlay implementations exists,
which atm don't (and it doesn't look like this is gonna change).

Open issues:
- Runs in sync with the gpu, i.e. unnecessary waiting. I've decided
  to wait on this because the hw tends to hang when changing something
  in this area. I left some dummy functions as infrastructure.
- polyphase filtering uses a static table.
- uses uninterruptible sleeps. Unfortunately the alternatives may
  unnecessarily wedged the hw if/when we timeout too early (and
  userspace only overloaded the batch buffers with stuff worth a few
  secs of gpu time).

Changes since v1:
- fix off-by-one misconception on my side. This fixes fullscreen
  playback.
Changes since v2:
- add underrun detection as spec'ed for i965.
- flush caches properly, fixing visual corruptions.
Changes since v4:
- fix up cache flushing of overlay memory regs.
- killed require_pipe_a logic - it hangs the chip.

48764bf43f drm/i915: add i915_lp_ring_sync helper
This just waits until the hw passed the current ring position with
cmd execution. This slightly changes the existing i915_wait_request
function to make uninterruptible waiting possible - no point in
returning to userspace while mucking around with the overlay, that
piece of hw is just too fragile.

Also replace a magic 0 with the symbolic constant (and kill the then
superflous comment) while I was looking at the code.

c9354c85c1 i915: fix intel graphics suspend breakage due to resume/lid event confusion
In commit c1c7af6089 ("drm/i915: force
mode set at lid open time") the intel graphics driver was taught to
restore the LVDS mode on lid open.

That caused problems with interaction with the suspend/resume code,
which commonly runs at the same time (suspend is often caused by the lid
close event, while lid open is commonly a resume event), which was
worked around with in commit 06891e27a9
("drm/i915: fix suspend/resume breakage in lid notifier").

However, in the meantime the lid event code had also grown a user event
notifier (commit 06324194ee: "drm/i915:
generate a KMS uevent at lid open/close time"), and now _that_ causes
problems with suspend/resume and some versions of Xorg reacting to those
uevents by setting the mode.

So this effectively reverts that commit 06324194ee, and makes the lid
open protection logic against suspend/resume more explicit.  This fixes
at least one laptop. See

	http://bugzilla.kernel.org/show_bug.cgi?id=14484

for more details.

0d9c778978 drm/i915: Install a fence register for fbc on g4x
To enable framebuffer compression on a g4x, we not only need the buffer
to tiled (X only), we also need to hold a fence register for the buffer.
Currently we only install a fence register for pre-i965s when setting up
the scanout buffer. Rather than adding some convoluted logic to
g4x_enable_fbc() to acquire a fence register, and perhaps to
g4x_disable_fbc() to release it again, we can extend the acquisition
during setup to all chipsets.

a3e17eb8f4 drm/i915: Set the LVDS_BORDER when using LVDS scaling mode
According to the spec the LVDS_BORDER_ENABLE bit decides whether the border
data should be included in the active display and data sent to the panel.
Border should be used when in VGA centered (un-scaled) mode or when scaling
a 4:3 source image to a wide screen panel (typical 16:9).

So when the LVDS scaling is used, decide whether the LVDS_BORDER should be
enabled or not according to the current scaling mode.

At the same time fix the typo error in LVDS center scaling mode.

b442962a9e drm/radeon/kms: add support for "Surround View"
"Surround View" is an option in the system bios that
enables the AMD IGP chip in conjunction with a
discrete AMD card.  However, since the IGP vbios is
part of the system bios it is not accessible via the
rom bar or the legacy vga location.  When "Surround View"
is enabled in the system bios, the system bios puts a
copy of the IGP vbios image at the start of vram.

This patch adds support for reading the vbios image out
of vram on IGP cards.

Even if the physical output connector is DVI, calling it HDMI
tells the user that there's HDMI audio signaling support.

0d0884cee3 drm/i915: Multiply the refresh by 1000 in TV mode validatiion
As of 559ee21d26 the actual refresh rate
is returned by the function of drm_mode_vrefresh, so multiply the refresh
rate by 1000 in TV mode validation.

At the same time the error is expanded from 10 to 1000.
