drm/nouveau/bios: improve error handling when reading the vbios from ACPI
drm/nouveau: handle same-fb page flips
This issue is a regression from 70790f4f81,
and causes us to miss a special-case for C51 (NV4E) chipsets and return
the wrong reference frequency for the VPLLs.

The big thing is the disabling of the hsw support by default, cc: stable.
We've aimed for basic hsw support in 3.6, but due to a few bad

On the worst scenario, users with new hardwares and old kernel from
enabling times can get black screens. So, from now on, this
perliminary_hw_support module parameter shall be used by all upcoming
platforms that are still under enabling. The second option would be to
merge the pci ids after basic modeset works, but that makes testing
and development while bringing up hw a rather tedious afair.
Although it is uncomfortable for developers use this extra variable it

This reverts commit 2477367083.
If (for whatever reason) the DP sink device never asks for the maximal
voltage level, we never don't hit the check that should bail us out
after 5 retries of the same voltage. Which leads to an endless loop in
the DP link training code, which hangs the driver.
Now some more DP link training experiments on eDP panels seem to
indicate that our training algorithm isn't robust enough anyway and
needs more work. Hence for 3.7-fixes, let's just revert the regressing
commit instead of trying to apply more duct-tape.

For TV and LVDS encoders intel_sdvo_set_input_timings_for_mode()
is called to pass a mode to the sdvo chip and retrieve a dtd
containing information needed to calculate the adjusted_mode which
is done by intel_sdvo_get_dtd_from_mode().
To set this adjusted_mode as input mode for the sdvo chip, a dtd is
recalculated using intel_sdvo_get_mode_from_dtd(). During this round
trip the sdvo_flags contained in the dtd obtained from the hardware
are lost.
Since these flags cannot be ignored in all cases this patch preserves
and restores them.

The DPLL multipiler is set up in intel_display.c:i9xx_update_pll()

There the DPLL multiplier is adjusted so that the SDVO gets a sufficient
bus clock.
When cloning a CRTC between an SDVO driven encoder and the standard
DAC the DAC setup code reseted the multiplier value to 1 thus undoing
the correct setup. There is no need to touch the multiplier in the DAC
setup code: the correct value (i.e. 1 in case no SDVO encoder is used)
is set by i9xx_update_pll() already.

This return was stupid to begin with since it may have left the card

corresponding to another one). The reclocking code will need to be

radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

Based on Dmitries work, but splitting the code into page

readable and (hopefully) more reliable.
Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.
Also using the fact that allocations from the SA are mostly
continuously (except for end of buffer wraps and under very

This seems to be the root-cause that breaks resume on my i855gm when I
apply the "drm/i915: fixup the plane->pipe fixup code" patch. And that
code doesn't even run on my machine, so it's pure timing changes
causing the regression.
Furthermore resume has been constantly switching between working and
broken on this machine ever since kms support has been merged,
seemingly with no related change as a root cause. And always with the
same symptoms of the backlight lighting up, but the lvds panel only
displaying black.
Also, of both i855gm variants only one is in the table. And in the
past we've only ever removed entries from this quirk table because it
breaks things.
So let's just remove it - in case there's indeed a bios out there
relying on a running pipe A, we can add back in a more precise quirk
entry, like all the others (save for i830/i845).
