Pass BIT(DRM_ROTATE_0) instead of DRM_ROTATE_0 to skl_update_scaler().
The former is a mask, the latter just the bit number.
Fortunately the only thing skl_update_scaler() does with the rotation
is check if it's 90/270 degrees or not, and so in this case it would
still do the right thing.

On SKL+ plane scaling is mutually exclusive with color keying. The code
check for this, but during some refactoring the code got changed to
also reject primary plane windowing when color keying is used. There is
no such restriction in the hardware, so restore the original logic.

LRC code was calling GEM API like i915_gem_obj_ggtt_offset from
places where the struct_mutex cannot be grabbed (irq handlers).
To avoid that this patch caches some interesting bits and values
in the engine and context structures.
Some usages are also removed where they are not needed like a
few asserts which are either impossible or have been checked
already during engine initialization.
Side benefit is also that interrupt handlers and command
submission stop evaluating invariant conditionals, like what
Gen we are running on, on every interrupt and every command
submitted.
This patch deals with logical ring context id and descriptors
while subsequent patches will deal with the remaining issues.
v2:
* Cache the VMA instead of the address. (Chris Wilson)
* Incorporate Dave Gordon's good comments and function name.
v3:
* Extract ctx descriptor template to a function and group
functions dealing with ctx descriptor & co together near
top of the file. (Dave Gordon)

Majority of them was duplicated code and only render ring
currently overrides some of them. We can save some lines of
code and also take away the confusion on why bsd2 did not
do the seqno coherency workaround. (VCS2 ring does not exist
on platforms where workaround is needed but that was not
documented in the code.)

This simplifies the exit path a little bit, makes the code

Kernel and userspace are able to handle 4GB (1<<32) address space range,
but "A32 Stateless Model" is not. According to documentation, A32 accesses
are based on General State Base Address and bound checking is in place.
Because size field (instruction State Base Address) limitation, it is not
possible to address full 4GB memory region.
A32 Stateless Model is used by some libraries and without this patch, the
last page of 4GB address space is not accessible in 32bit processes.

commit 10afa0b65fe2 ("drm/i915: Reject >9 ddi translation entried if port != A/E on SKL")
added sanity checks to make sure we don't end up with too many ddi translation
values for eDP ports, but it actually failed to check if the port is eDP.
We still look up the edp translations for non-eDP ports, but don't use
them, so we shouldn't be complaining about them either.

MI_BATCH_BUFFER is nasty since it requires that userspace pass in the
correct batch length.
Let's switch to using MI_BATCH_BUFFER_START instead (like we do on
other platforms). Then we don't have to specify the batch length
at all, and the CS will instead execute until it sees the
MI_BATCH_BUFFER_END.
We still need the batch length since we do the CS TLB workaround
and copy the batch into the permanently pinned scratch object
and execute it from there. But for this we can simply use the
batch object length when the user hasn't specified the actual
batch length. So specifying the batch length becomes just a
way to optimize the batch copy a little bit.
We lost batch_len from a bunch of igts (including the quiesce batch)
so without this igt is utterly broken on 830/845. Also some igts such
as gem_cpu_reloc never specified the batch_len and so didn't work.
With MI_BATCH_BUFFER_START we don't have to fix up igt every time
someone forgets that 830/845 exist.

My 85x has VBT version 108 which has a child dev size of 27 bytes.
Let's allow that without printing an error.
We still want to reject the actual parsin since for that we need
the child device size to be at least 33 bytes. So we should still
check for that, but let's make it print a debug message only instead
of an error.
While at it, toss in a BUILD_BUG_ON() to verify our struct
old_child_dev_config is in fact 33 bytes.

We use the vblank timestamps to generate the vblank frame counter value
on gen2. That means we need the pipe scanout position to be accurate
when we call drm_crtc_vblank_on(), otherwise the frame counter
guesstimate may jump when the pipe actually start.
What I observed on my 85x is that the DSL initially reads 0, and when
the pipe actually starts DSL jumps to vblank_start. On gen2 DSL==0 means
actually vtotal-1 (see update_scanline_offset()), so if we initially
get vtotal-1, and then very quickly vblank_start (or thereabouts), the
scanout position will appear to jump backwards by approximately one
vblank length. Which means the frame counter guesstimate will also
jump backwards. That's no good, so let's make sure the pipe has
started before we call drm_crtc_vblank_on().

We're supposed to pass the primary DP encoder to intel_ddi_clk_select(),
not the fake MST encoder. Do so.
There's no real bug here though, since intel_ddi_clk_select() only
checks if the encoder type is EDP (which it isn't for either the
primary DP encoder or the fake MST encoder), and it gets the DDI port
via intel_ddi_get_encoder_port() (which knows how to do the
fake->primary->port dance itself).
