Move the assert_vblank_disabled() into intel_crtc_vblank_on()
so that we don't have to inline it all over.
This does mean we now assert_vblank_disabled() during readout as well
but that is totally fine as it happens after drm_crtc_vblank_reset().
One can even argue it's what we want to do anyway to make sure
the reset actually happened.

In order to avoid some nasty mutex inversions, commit 09c5ab384f
("drm/i915: Keep rings pinned while the context is active") allowed the
intel_ring unpinning to be run concurrently with the next context
pinning it. Thus each step in intel_ring_unpin() needed to be atomic and
ordered in a nice onion with intel_ring_pin() so that the lifetimes
overlapped and were always safe.
Sadly, a few steps in intel_ring_unpin() were overlooked, such as
closing the read/write pointers of the ring and discarding the
intel_ring.vaddr, as these steps were not serialised with
intel_ring_pin() and so could leave the ring in disarray.

I was debugging an issue that ended up fixed by commit a096883dda

puzzled how these atomic operations were guaranteeing atomicity.
if (atomic_add_return(1, &dsb->refcount) != 1)
return dsb;
Thread A could still be initializing dsb struct (and even fail in the
middle) while thread B would take a reference and use it (even
derefencing a NULL cmd_buf).
I don't think the atomic operations here will help much if this were
to support multithreaded scenario in future, so just remove them to
avoid confusion.

VBT revision 229 adds a new "Generic DTD" block 58 and deprecates the
old LFP panel mode data in block 42. Let's start parsing this block to
fill in the panel fixed mode on devices with a >=229 VBT.
v2:
* Update according to the recent updates:
- DTD size is now 16 bits instead of 24
- polarity is now just a single bit for hsync and vsync and is
properly documented
* Minor checkpatch fix
v3:
* Now that panel options are parsed separately from the previous patch,
move generic DTD parsing into a function parallel to
parse_lfp_panel_dtd. We'll still fall back to looking at the legacy
LVDS timing block if the generic DTD fails. (Jani)
* Don't forget to actually set lfp_lvds_vbt_mode! (Jani)
* Drop "bdb_" prefix from dtd entry structure. (Jani)
* Follow C99 standard for structure's flexible array member. (Jani)
v4:
* Add "positive" to polarity field names for clarity. (Jani)
* Move VBT version check and fallback to legacy DTD parsing logic to a
helper to keep top-level VBT parsing uncluttered. (Jani)
* Restructure reserved bit packing at end of generic_dtd_entry from
"u32 rsvd:24" to "u8 rsvd[3]" to prevent copy/paste mistakes in the
future. (Jani)

bits decided to move elsewhere on HSW, so on many platforms
we're not doing anything at all here. Also we're forgetting

Add all the bit definitions for the various homes these bits
have had throughout the years, and reset them all to zero.
However I'm not entirely sure this is a safe thing to do. If
not I guess we'd want full readout+statecheck for this stuff.

Our callers fall into two categories, those passing timeout=0 who just
want to flush request retirements and those passing a timeout that need
to wait for submission completion (e.g. intel_gt_wait_for_idle()).
Currently, we only wait for a snapshot of timelines at the start of the
wait (but there was an expectation that new requests would cause timelines
to appear at the end). However, our callers, such as
intel_gt_wait_for_idle() before suspend, do require us to wait for the
power management requests emitted by retirement as well. If we don't,
then it takes an extra second or two for the background worker to flush
the queue and mark the GT as idle.
