b4c26818ae drm/nouveau/mxm: initial implementation of dcb sanitisation
The DCB table provided by the VBIOS on most MXM chips has a number of
entries which either need to be disabled, or modified according to the
MXM-SIS Output Device Descriptors.

The x86 vbios code usually takes care of this for us, however, with the
large number of laptops now with switchable graphics or optimus, a lot
of the time nouveau is responsible for POSTing the card instead - leaving
some fun situations like, plugging in a monitor and having nouveau decide
3 connectors actually just got plugged in..

No MXM-SIS fetching methods implemented yet.

befb51e9c9 drm/nouveau/disp: parse connector info directly in nouveau_connector.c
Another case where we parsed vbios data to some structs, then again use
that info once to construct another set of data.  Skip the intermediate
step.

This is also slightly improved in that we can now use DCB 3.x connector
table info, which will allow NV4x to gain hotplug support, and to make
quirks for SPWG LVDS panels unnecessary.

f553b79c03 drm/nouveau/i2c: handle bit-banging ourselves
i2c-algo-bit doesn't actually work very well on one card I have access to
(NVS 300), random single-bit errors occur most of the time - what we're
doing now is closer to what xf86i2c.c does.

The original plan was to figure out why i2c-algo-bit fails on the NVS 300,
and fix it.  However, while investigating I discovered i2c-algo-bit calls
cond_resched(), which makes it a bad idea for us to be using as we execute
VBIOS scripts from a tasklet, and there may very well be i2c transfers as
a result.

So, since I already wrote this code in userspace to track down the NVS 300
bug, and it's not really much code - lets use it.

2bdb06e3cf drm/nouveau/i2c: tidy up bit-bang helpers, also fixing nv50 setsda bug
Was using nv_mask, which is bad.  Reading the reg senses the current line
states, which aren't necessarily the states we're trying to drive the
lines to.

Fixed to store SCL driver state just as we already do for SDA.

84e052e626 drm/nvd0/disp: handle yet another interrupt
Spotted while messing with overlay channels (probably as a result of
sending a similar "disable" sequence as we do for the flip channels).

The value in 0x61008c was 0x20, which one would reasonably guess is
"bit 5 == something to report about evo channel 5" - but who knows.

Spotted the binary driver getting this too, and it appears to not do
anything exciting as a result.  So, handle it the same way and avoid
an IRQ storm.

6934618014 drm/nv40/pm: convert to new pwm hooks, also fixing pwm type detection
A NV49 appeared a while back that was using the "nv41 style" pwm registers,
rather than the "nv40 style" ones my board is using.  This disproves the
previous theory that the pwm controller choice is chipset-specific.

So, after looking at a bunch of vbios images it appears that the next viable
theory is that we should select the pwm controller to use based on the gpio
line the fan is tied to, just like we do on nv50.

a175094cd8 drm/nouveau/pm: introduce generic handler for on-chip fan controller
The handling of the internal pwm fan controller is similar enough between
current chipsets that it makes sense to share the logic, and bugfixes :)

No hw backends converted yet, will automatically fall-through to the
"old" per-chipset fanspeed hooks for now.

Exposes the following sysfs entries:
- fan0_input: read the rotational speed of the fan (poll a bit during 250ms)
- pwm0: set the pwm duty cycle
- pwm0_min/max: set the minimum/maximum pwm value

v2 (Ben Skeggs):
- nv50 pwm controller code removed in favour of other more complete code
- FAN_RPM -> FAN_SENSE
- merged FAN_SENSE readout into common code, not at all nv50-specific
- protected fanspeed changes with perflvl_wr
- formatting tidying
- added some comments where things are shaky

v3 (Martin Peres)
- ensure duty min/max from thermal table are sane

c75488376a drm: call connector dpms fxn, when setting config
Call connector->funcs->dpms(DPMS_ON) rather than just setting
connector->dpms = DPMS_ON.  This ensures that if the connector
has something to do to enable the output (rather than just using
drm_helper_connector_dpms helper directly), that this happens
at bootup.  This solves an issue with connectors not getting
enabled from fbcon_init() when the driver is loaded.

If the bpc is set from the connector is 0, we then use it later to adjust

passing a 0 pixel clock into the code.

I'm not sure if this is the correct answer or if we should avoid the HDMI
clock adjustment for 0 values.

30eb77f4e6 drm/radeon: precompute fence cpu/gpu addr once v3
Add a start fence driver helper function which will be call
once for each ring and will compute cpu/gpu addr for fence
depending on wether to use wb buffer or scratch reg.

This patch replace initialize fence driver separately which
was broken in regard of GPU lockup. The fence list for created,
emited, signaled must be initialize once and only from the
asic init callback not from the startup call back which is
call from the gpu reset.

v2: With this in place we no longer need to know the number of
    rings in fence_driver_init, also writing to the scratch reg
    before knowing its offset is a bad idea.

5736995b47 gma500: Replace SDVO code with slightly modified version from i915
Our current SDVO implementation is not working properly, so replace it with
a modified version of the i915. Further testing and debugging is needed to make
sure we can handle the different SDVO setups and wiring.

9c8cee4713 gma500: Convert PSB LVDS to new output handling
LVDS for PSB now uses psb_intel_encoder and psb_intel_connectors instead of
psb_intel_output. i2c_bus and ddc_bus are moved to lvds_priv. There was also a
pointer to mode_dev (for no obvious reason) that we now get directly from
dev_priv.

59df7b1771 drm/intel: Fix initialization if startup happens in interlaced mode [v2]
My EFI BIOS starts the graphics card up in my projector's preferred EDID
mode, 1080@60i. The Intel driver does not clear all the interlaced bits.

This patch introduces a new PIPECONF_INTERLACE_MASK define and uses it
to restore progressive mode.

4966b2a935 Fix wrong assumptions in cea_for_each_detailed_block v2
The current logic misunderstands the spec about CEA 18byte descriptors.
First, the spec doesn't state "detailed timing descriptors" but "18 byte
descriptors", so any data record could be stored, mixed timings and
other data, just as in the standard EDID.
Second, the lower four bit of byte 3 of the CEA record do not contain
the number of descriptors, but "the total number of DTDs defining native
formats in the whole EDID [...], starting with the first DTD in the DTD
list (which starts in the base EDID block)." A device can of course
support non-native formats.

As such the number can't be used to determine n, and the existing code
will filter non-timing 18byte descriptors anyway.

097354eb14 drm/i915: check ACTHD of all rings
Otherwise hangcheck spuriously fires when running blitter/bsd-only
workloads.

Contrary to a similar patch by Ben Widawsky this does not check
INSTDONE of the other rings. Chris Wilson implied that in a failure to
detect a hang, most likely because INSTDONE was fluctuating. Thus only
check ACTHD, which as far as I know is rather reliable. Also, blitter
and bsd rings can't launch complex tasks from a single instruction
(like 3D_PRIM on the render with complex or even infinite shaders).

This fixes spurious gpu hang detection when running
tests/gem_hangcheck_forcewake on snb/ivb.

The GEN7_* register addresses actually take effect since GEN6 and should
