On SandyBridge IPS was entirely implemented in hardware and not reliant
on the driver monitoring power consumption and feeding back desired run
states, so the hardware is able to adapt quicker and more flexibly. Which
is a huge relief for us as we no longer have to carry empirically
derived magic algorithms.
Yet despite the advance in technology, the driver was still doing its
IPS polling on all machines. Restrict it to the only supported hardware,
Clarkdale/Arrandale.

Clearing bit 5 of CACHE_MODE_0 is necessary to prevent GPU hangs in
OpenGL programs such as Google MapsGL, Google Earth, and gzdoom when
using separate stencil buffers. Without it, the GPU tries to use the
LRA eviction policy, which isn't supported. This was supposed to be off
by default, but seems to be on for many machines.
This cannot be done in gen6_init_clock_gating with most of the other
workaround bits; the render ring needs to exist. Otherwise, the
register write gets dropped on the floor (one printk will show it
changed, but a second printk immediately following shows the value
reverts to the old one).

- VGA load-detect fix. This bug seems to be as old as the load-detect code
(2.6.30), but needs stupid userspace (upowerd trying to detect
connectors on dpms-off outputs) to actually kill the machine. And
obviously a machine without VGA-hotplug, otherwise we don't do load
detect.

We seem to have a decent confusion between the output timings and the
input timings of the sdvo encoder. If I understand the code correctly,
we use the original mode unchanged for the output timings, safe for
the lvds case. And we should use the adjusted mode for input timings.
Clarify the situation by adding an explicit output_dtd to the sdvo
mode_set function and streamline the code-flow by moving the input and
output mode setting in the sdvo encode together.
Furthermore testing showed that the sdvo input timing needs the
unadjusted dotclock, the sdvo chip will automatically compute the
required pixel multiplier to get a dotclock above 100 MHz.
Fix this up when converting a drm mode to an sdvo dtd.
This regression was introduced in

/* If it's a TV, we already set the output timing in mode_fixup.
* Otherwise, the output timing is equal to the input timing.
Due to questions raised in review, below a more elaborate analysis of
the bug at hand:
Sdvo seems to have two timings, one is the output timing which will be
sent over whatever is connected on the other side of the sdvo chip (panel,
hdmi screen, tv), the other is the input timing which will be generated by
the gmch pipe. It looks like sdvo is expected to scale between the two.
To make things slightly more complicated, we have a bunch of special
cases:
- For lvds panel we always use a fixed output timing, namely
intel_sdvo->sdvo_lvds_fixed_mode, hence that special case.
- Sdvo has an interface to generate a preferred input timing for a given
output timing. This is the confusing thing that I've tried to clear up
with the follow-on patches.
- A special requirement is that the input pixel clock needs to be between
100MHz and 200MHz (likely to keep it within the electromechanical design
range of PCIe), 270MHz on later gen4+. Lower pixel clocks are
doubled/quadrupled.
The thing this patch tries to fix is that the pipe needs to be
explicitly instructed to double/quadruple the pixels and needs the
correspondingly higher pixel clock, whereas the sdvo adaptor seems to
do that itself and needs the unadjusted pixel clock. For the sdvo
encode side we already set the pixel mutliplier with a different
command (0x21).
This patch tries to fix this mess by:
- Keeping the output mode timing in the unadjusted plain mode, safe
for the lvds case.
- Storing the input timing in the adjusted_mode with the adjusted
pixel clock. This way we don't need to frob around with the core
crtc mode set code.
- Fixing up the pixelclock when constructing the sdvo dtd timing
struct. This is why the first hunk of the patch is an integral part
of the series.
- Dropping the is_tv special case because input_dtd is equivalent to
adjusted_mode after these changes. Follow-up patches clear this up
further (by simply ripping out intel_sdvo->input_dtd because it's
not needed).

Somehow we have a fast-path that tries to avoid going through
the load-detect code when the encode already has a crtc associated.
But this fails horribly when the crtc is off. The load detect pipe
itself manages this case well (and also does not forget to restore the
dpms state), so just rip out this special case.
The issue seems to go back all the way to the commit that originally
introduced load-detection on the vga output:

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.
This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c. But that way we don't have
to export our internal do_mmap_pgoff() function.
Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead. We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

This fixes a resume regression introduced in
commit 7dd4906586274f3945f2aeaaa5a33b451c3b4bba

Date: Wed Mar 21 10:48:18 2012 +0000
drm/i915: Mark untiled BLT commands as fenced on gen2/3
which fixed fencing tracking for untiled blt commands.
A side effect of that patch was that now also untiled objects have a
non-zero obj->last_fenced_seqno to track when a fence can be set up
after a pipelined tiling change. Unfortunately this was only cleared
by the fence setup and teardown code, resulting in tons of untiled but
inactive objects with non-zero last_fenced_seqno.
Now after resume we completely reset the seqno tracking, both on the
driver side (by setting dev_priv->next_seqno = 1) and on the hw side
(by allocating a new hws page, which contains the seqnos). Hilarity
and indefinite waits ensued from the stale seqnos in
obj->last_fenced_seqno from before the suspend.
The fix is to properly clear the fencing tracking state like we
already do for the normal gpu rendering while moving objects off the
active list.
