Pineview is just different.
Also split out i9xx_clock from intel_clock and drop the now redundant
struct device * parameter.
Note that in this patch I kill an XXX comment about 100MHz clocks. I
couldn't figure out what this is about, and we don't seem to have any
bug reports about this either. I suspect that it's a remnant from when
the i9xx and ilk+ modeset code was all in the same file since ilk+
does indeed have a 100MHz clock. So I've just killed it to stop the
cargo-culting.

Since this is run in the compute config stage we need to check
the new_ pointers, i.e the stage output routing, not the current
modeset layout. Also there was a little logic bug in properly skipping
connectors: The old code did not skip any unused connectors and so
clamped to whatever was left in there (usually 0 if that connector
hasn't seen a EDID 1.4 screen ever since boot-up).
This has been broken when moving the pipe bpp selection in

drm/i915: precompute pipe bpp before touching the hw
To avoid too much casting switch from drm_ to intel_ types.
Also add a bit of debug output to help reconstructing what's going
on.
v2: Try to clarify this a bit:
- s/pipe_config_set_bpp/compute_baseline_pipe_bpp/ to make it clearer
at which stage this function is run. Also add a comment about what
it does.
- Extract the sink clamping into it's own function.
v3: Actually make it compile.
v4: Split out all the prep refactoring to make the bugfix stick out
really badly. Also elaborate a bit in the commit message about the
nature of the bugfix.

As a prep work to fix it up:
- Use intel_connector instead of drm_connector to avoid too much
upcasting in the bugfix patch.
- Extract the connector bpp clamping from the loop-over-connectors
logic.
- Bikeshed function names (to make it clearer that
acompute_baseline_pipe_bpp runs in the compute stage of the modeset
sequence) and add a comment to make it clearer what it does.
No functional change in this patch.

Use container_of() instead of a cast to get struct intel_fbdev
from struct drm_fb_helper.
Also populate the fb_info->par correctly with the drm_fb_helper pointer
instead of the intel_fbdev pointer.
There's no actual functional change since the drm_fb_helper happens to

Keep track of ring seqno progress and if there are no
progress detected, declare hang. Use actual head (acthd)
to distinguish between ring stuck and batchbuffer looping
situation. Stuck ring will be kicked to trigger progress.
This commit adds a hard limit for batchbuffer completion time.
If batchbuffer completion time is more than 4.5 seconds,
the gpu will be declared hung.
Review comment from Ben which nicely clarifies the semantic change:
"Maybe I'm just stating the functional changes of the patch, but in case
they were unintended here is what I see as potential issues:
1. "If ring B is waiting on ring A via semaphore, and ring A is making
progress, albeit slowly - the hangcheck will fire. The check will
determine that A is moving, however ring B will appear hung because
the ACTHD doesn't move. I honestly can't say if that's actually a
realistic problem to hit it probably implies the timeout value is too
low.
2. "There's also another corner case on the kick. If the seqno = 2
(though not stuck), and on the 3rd hangcheck, the ring is stuck, and
we try to kick it... we don't actually try to find out if the kick
helped"
v2: use atchd to detect stuck ring from loop (Ben Widawsky)
v3: Use acthd to check when ring needs kicking.
Declare hang on third time in order to give time for
kick_ring to take effect.
v4: Update commit msg

The way the stolen handling works is we take a pin on the backing pages,
but we never actually get a reference to the bo. On freeing objects
allocated with stolen memory, the final unref will end up freeing the
object with pinned pages count left. To enable an assertion to catch
bugs in this code path, this patch cleans up that remaining pin.

These changes are mostly minor fixes to things introduced in 3.10. The

submissions from userspace and wasn't working properly. All other

around.

The firewall was reinitialised for each gather. Because the filter
was reinitialised, it did not track the class over gather boundaries.
This allowed the user application to set host1x class to one class
in one gather and use that class in another gather without firewall
having knowledge about that.

The firewall assumed that the user space always delivers a relocation
table when it is accessing address registers. If userspace did not
deliver a relocation table and tried to access the address registers,
the code performed bad memory accesses.
This patch modifies the firewall to check correctly that the firewall
table is available before accessing it. In addition, check_reloc() is
converted to use boolean return value (true when the reloc is valid,
false when invalid).

So it looks like for virtual hw cursors on QXL we need to inform
the "hw" device what the cursor hotspot parameters are. This
makes sense if you think the host has to draw the cursor and interpret
clicks from it. However the current modesetting interface doesn't support
passing the hotspot information from userspace.
This implements a new cursor ioctl, that takes the hotspot info as well,
userspace can try calling the new interface and if it gets -ENOSYS it means
its on an older kernel and can just fallback.

The tilcdc has a number of limitations for the allowed sizes of
the various adjustable timing parameter. Some modes are outside
of these timings. This commit will prune modes that report timings
that will overflow the allowed sizes in the tilcdc.

When hooking up to an HDMI analyzer noticed some timings were
off by one. Referring to the hardware technical reference manual
for the lcd controller some of the timing registers use 0 to
represent 1. This patch addresses that issue.

1024 pixels to be specified (upto 2048). This patch
adds support for setting this bit on LCDC V2.

At the larger resolutions, the g200e series sometimes struggles with
maintaining a proper output. Problems like flickering or black bands appearing
on screen can occur. In order to avoid this, limitations regarding resolutions
and bandwidth have been added for the different variations of the g200e series.
This code was ported from the old xorg mga driver.

drm_mode_detailed() is called quite often, therefore when a monitor
that has a detailed timing mode marked DRM_EDID_PT_STEREO or requiring
composite sync, warning messages will clutter up the kernel log.
Like we already do for incorrect hsync/vsync pluse widths, print these
messages only when KMS debugging is enabled.

but the caller is not the DRM-Master because file_priv->is_master = 0.
Fix that by returning to ioctl caller the driver master_set error code.

There's a race window (small for hpd, 10s large for polled outputs)
where userspace could sneak in with an unrelated connnector probe
ioctl call and eat the hotplug event (since neither the hpd nor the
poll code see a state change).
To avoid this, check whether the connector state changes in all other
->detect calls (in the current helper code that's only probe_single)
and if that's the case, fire off a hotplug event. Note that we can't
directly call the hotplug event handler, since that expects that no
locks are held (due to reentrancy with the fb code to update the kms
console).
Also, this requires that drivers using the probe_single helper
function set up the poll work. All current drivers do that already,
and with the reworked hpd handling there'll be no downside to
unconditionally setting up the poll work any more.

Drivers are allowed (actually have to) disable unrelated crtcs in
their ->set_config callback (when we steal all the connectors from
that crtc). If they do that they'll clear crtc->fb to NULL.
Which results in a refcount leak, since the drm core is keeping track
of that reference.
To fix this track the old fb of all crtcs and adjust references for
all of them. Of course, since we only hold an additional reference for
the fb for the current crtc we need to increase refcounts before we
drop the old one.
This approach has the benefit that it inches us a bit closer to an
atomic modeset world, where we want to update the config of all crtcs
in one step.
This regression has been introduce in the framebuffer refcount
conversion, specifically in
