The idea is to flag a power state with a certain type and use
that type to decide on what state to select. On r6xx+, we
select a state and then transition between clock modes in that
state. On pre-r6xx, we transition between states directly.

The general idea is to validate the current hw state
against the set of power states and select a power
state based on that. This patch just pulls the power
states from the bios and prints the information. It
is not currently hooked up in the actual power management
code. Hooking it up will require reworking the the current
power state selection code and will be handled in a future
patch.
Additionally, we'd need to decide on some default lower
power states for cards without power tables.
v2 - increment state_index after checking for default state
v3 - fix typo in pm init on pre-atom cards, handle pre-atom
cards without x86 bioses

Only flush the gpu caches before we submit a fence.
This leads to a small performance boost when we take
the extra gpu cache flushes out of the ddx and mesa.
Once this patch is in and the drm version is bumped,
we can remove the flushes from the ddx and drm.
Also, remove the extra cache flushes from the blit
routine.

Rework the pll algo selection so that the pll algo
in use can be selected more easily. This allows
us to select different pll divider selection algos
for specific monitors that work better with one algo
or the other. This is needed for the next patch which
adds an LVDS pll quirk for a specific notebook.

In order to improve our diagnostic capabilities following a GPU hang
and subsequent reset, we need to record the batch buffer that triggered
the error. We assume that the current batch buffer, plus a few details
about what else is on the active list, will be sufficient -- at the very
least an improvement over nothing.
The extra information is stored in /debug/dri/.../i915_error_state
following an error, and may be decoded using
intel_gpu_tools/tools/intel_error_decode.
v2: Avoid excessive work under spinlocks.
v3: Include ringbuffer for later analysis.
v4: Use kunmap correctly and record more buffer state.
v5: Search ringbuffer for current batch buffer
v6: Use a work fn for the impossible IRQ error case.
v7: Avoid non-atomic paths whilst in IRQ context.

i915_gem_object_fenceable was mostly just a repeat of the
i915_gem_object_fence_offset_ok, but also checking the size (which was
checkecd when we allowed that BO to be tiled in the first place). So
instead, export the latter function and use it in place.

This aligns it with the other user of i915_gem_clear_fence_reg,
which blows away the mapping before changing the fence reg.
Only affects userspace if it races against itself when changing
tiling parameters, i.e. behaviour is undefined, anyway.

No functional change, because gtt flushing is a no-op. Still, try
to keep the bookkeeping accurate. The if is still slightly wrong
for with execbuf2 even i915-class hw doesn't always need a fence
reg for gpu access. But that's for somewhen lateron.

He Shuang reported an OGLC performance regression introduced in the patch
"enable memory self refresh on 9xx", In that patch, SR on 945 is disabled
everytime when calling intel_mark_busy(), while too much of such operation
will impact performance. Actually disable SR is necessary only when GPU and
Crtc changing from idle to busy. This patch make such optimization.

Ironlake (and 965GM, which this patch doesn't support) supports a
hardware performance and power management feature that allows it to
adjust to changes in GPU load over time with software help. The goal
if this is to maximize performance/power for a given workload.
This patch enables that feature, which is also a requirement for
supporting Intelligent Power Sharing, a feature which allows for
dynamic budgeting of power between the CPU and GPU in Arrandale
platforms.

Enabling memory self refresh (SR) on 9xx needs to set additional
register bits. On 945, we need bit 31 of FW_BLC_SELF to enable the
write to self refresh bit and bit 16 to enable the write of self
refresh watermark. On 915, bit 12 of INSTPM is used to enable SR.
SR will take effect when CPU enters C3+ state and its entry/exit
should be automatically controlled by H/W, driver only needs to set
SR enable bits in wm update. But this isn't safe in my test on 945
because GPU is hung. So this patch explicitly enables SR when GPU
is idle, and disables SR when it is busy. In my test on a netbook of
945GSE chipset, it saves about 0.8W idle power.

With the introduction of the hang-check, we can safely expect that
i915_wait_request() will always return even when the GPU hangs, and so
do not need to open code the wait in order to manually check for the
hang. Also we do not need to always evict all buffers, so only flush
the GPU (and wait for it to idle) for KMS, but continue to evict for UMS.
