This allows the user to set a mode larger than the native one, useful
if we had trouble finding the actual native mode (e.g. because it goes
above the hardware bandwidth limits).

We aren't currently using tiling in userspace on evergreen,
but the info we currently return for the tiling info query
(gb_addr_config) is no adequate for userspace tiling alignment
calculations. It does not contain the bank info. Create a custom
tiling info dword with all the necessary info (num channels,
num banks, group size, row size).

We were previously dropping alignment requests on the floor
when allocating buffers so we always ended up page aligned.
Certain tiling modes on 6xx+ require larger alignment which
wasn't happening before.

The eDP panel must be powered up for aux transactions, so power it
up for detect and mode probe functions, otherwise power it up or
down based on dpms.
v2:
- only mess with eDP panel on DCE4+
- only mess with eDP panel on eDP connectors, not all DP connectors
v3:
- be extra careful to only mess with eDP panels on eDP connectors
v4:
- avoid possible null derefernce if a connector has not been
assigned to the encoder

If there was no connector mapped to the encoder, atombios_get_encoder_mode()
returned 0 which is the id for DP. Return something sane instead based on
the encoder id. This avoids hitting the DP paths on non-DP encoders.

Tiled buffers have the same alignment requirements regardless of
whether the surface is for db, cb, or textures. Previously, the
calculations where inconsistent for each buffer type.
- Unify the alignment calculations in a common function
- Standardize the alignment units (pixels for pitch/height/depth,
bytes for base)
- properly check the buffer base alignments

Currently an invalid EDID extension will cause the whole EDID to be considered invalid. Instead just drop the invalid extensions, and return the valid ones. The base block is modified to claim to have the number valid extensions, and the check sum is updated.
For my EIZO S2242W the base block is fine, but the extension block is all zeros. Without this patch I get no X and no VTs.

only, including list manipulation associated with reserving buffer objects.

Commit 219adae1 cached the EDID found during LVDS init, but in the
process prevented the init routine from discovering the preferred
fixed-mode for the panel. This was causing us to guess the correct mode,
which sometimes is wide of the mark.

My Sandybridge only reports 0 for the ring buffer registers, causing it
to hang as soon as we exhaust the available ring. As a workaround, take
advantage of our huge ring buffers and use the auto-reporting mechanism
to update the status page with the HEAD location every 64 KiB.

Xorg/1401 is trying to acquire lock:

which lock already depends on the new lock.
When the locking around the pwrite ioctl was simplified, I did not spot
that the phys path never took any locks and so we introduced this
potential circular reference.
