drm/i915/bios: Avoid temporary allocation whilst searching for downclock
Alan Cox reported a missing check on the kmalloc return value for the
allocation of a temporary mode used for searching for the LVDS downlock
frequency. This allocation is roughly 200 bytes, a little too large to
friviously place on the stack. However, we can simply use the few bytes
we need stored within the original DVO timing data, skip the translation
and do the compare directly between the timing data rather than on a
mode, thus avoiding the need for any temporary allocations.

This reverts commit 633f2ea26665d37bb3c8ae30799aa14988622653 and the
attempted fix dcbe6f2b3d136995915e2f9ecc7d4f3b28f47b6c.
There is a single clock source used for both SSC (some LVDS and DP) and
non-SSC (VGA, DVI) outputs. So we need to be careful to only enable SSC
as necessary. However, fiddling with DREFCLK was causing DP links to be
dropped and we do not have a fix ready, so revert.

drm/i915: Override SDVO panel type in VBT
Judging by comments in the BIOS, if the SDVO LVDS option h40 is enabled,
then we are supposed to query the real panel type via Int15. We don't do
this and so for the Sony Vaio VGC-JS210J which has otherwise default
values, we choose the wrong mode.
This patch adds a driver option, i915.vbt_sdvo_panel_type, which can be

drm/i915: Disable SSC for outputs other than LVDS or DP
For CRT and SDVO/HDMI, we need to use a normal, non-SSC, clock and so we
must clear any enabling bits left-over from earlier outputs. And also
seems to correct the LVDS panel on the Lenovo U160.
However, at one point, it did cause an "ERROR failed to disable

The i915 driver normally assumes the video bios has configured several

If these are not correct then although the panel looks ok, output from an

drm/i915: Use the VBT from OpRegion when available (v3)
It is recommended that we use the Video BIOS tables that were copied
into the OpRegion during POST when initialising the driver. This saves
us from having to furtle around inside the ROM ourselves and possibly
allows the vBIOS to adjust the tables prior to initialisation.
On some systems, such as the Samsung N210, there is no accessible VBIOS
and the only means of finding the VBT is through the OpRegion.
v2: Rearrange the code so that ASLE is enabled along with ACPI

drm/i915: Fix DDC bus selection for multifunction SDVO
Multifunction SDVO cards stopped working after 14571b4, and would report
something that looked remarkably like an ADD2 SPD ROM instead of EDID.
This appears to be because DDC bus selection was utterly horked by that
commit; controlled_output was no longer always a single bit, so
intel_sdvo_select_ddc_bus would pick bus 0, which is (unsurprisingly)
the SPD ROM bus, not a DDC bus.
So, instead of that, let's just use the DDC bus the child device table
tells us to use. I'm guessing at the bitmask and shifting from VBIOS
dumps, but it can't possibly be worse.

drm/i915: Check whether the LVDS downclock is found in VBT
Enumerate the LVDS panel timing info entry list in VBT to check whether
the LVDS downclock is found. If found, the downclock is also used to switch
dynamically between low and high frequency for LVDS.

drm/i915: add dynamic clock frequency control
There are several sources of unnecessary power consumption on Intel
graphics systems. The first is the LVDS clock. TFTs don't suffer from
persistence issues like CRTs, and so we can reduce the LVDS refresh rate
when the screen is idle. It will be automatically upclocked when
userspace triggers graphical activity. Beyond that, we can enable memory
self refresh. This allows the memory to go into a lower power state when
the graphics are idle. Finally, we can drop some clocks on the gpu
itself. All of these things can be reenabled between frames when GPU
activity is triggered, and so there should be no user visible graphical
changes.

This adds embedded DisplayPort support on next mobile chip which

drm/I915: Fix offset to DVO timings in LVDS data
Now the DVO timing in LVDS data entry is obtained by using the
following step:
a. get the entry size for every LVDS panel data
b. Get the LVDS fp entry for the preferred panel type
c. get the DVO timing by using entry->dvo_timing
In our driver the entry->dvo_timing is related with the size of
lvds_fp_timing. For example: the size is 46.
But it seems that the size of lvds_fp_timing varies on the differnt
platform. In such case we will get the incorrect DVO timing entry
because of the incorrect DVO offset in LVDS panel data entry.
This also removes a hack on new IGDNG to get proper DVO timing.
Calculate the DVO timing offset in LVDS data entry to get the DVO timing
a. get the DVO timing offset in the LVDS fp data entry by using the
pointer definition in LVDS data ptr
b. get the LVDS data entry
c. get the DVO timing by adding the DVO timing offset to data entry

drm/i915: fix LFP data fetch
Apparently the proper way to do this is to use the LFP data pointer
block to figure out the LFP data block entry size, then use that plus
the panel index to calculate an offset into the LFP data block array.
Similar fix has already been pushed to the 2D driver to fix fdo bug
applied to the VBIOS reader, and things look sane).

DRM: i915: add mode setting support
This commit adds i915 driver support for the DRM mode setting APIs.
Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are
supported. HDMI, DisplayPort and additional SDVO output support will
follow.
Support for the mode setting code is controlled by the new 'modeset'
module option. A new config option, CONFIG_DRM_I915_KMS controls the
default behavior, and whether a PCI ID list is built into the module for
use by user level module utilities.
Note that if mode setting is enabled, user level drivers that access
display registers directly or that don't use the kernel graphics memory
manager will likely corrupt kernel graphics memory, disrupt output
configuration (possibly leading to hangs and/or blank displays), and
prevent panic/oops messages from appearing. So use caution when
enabling this code; be sure your user level code supports the new
interfaces.
A new SysRq key, 'g', provides emergency support for switching back to
the kernel's framebuffer console; which is useful for testing.
