DMT Version 1.0, Rev. 13 lists a bunch of new modes we don't currently

The order may look a bit weird since it's not sorted based on the DMT

are ordered by the resolution, pixel clock, or some such factor. I
decided that it's perhaps best to keep the same order as the spec.

Completely different approach: Instead of encoding each and every
framebuffer update as spice operation simply update the shadow
framebuffer and maintain a dirty rectangle. Also schedule a worker
to push an update for the dirty rectangle as spice operation. Usually
a bunch of dirty rectangle updates are collected before the worker
actually runs.
What changes: Updates get batched now. Instead of sending tons of
small updates a few large ones are sent. When the same region is
updated multiple times within a short timeframe (scrolling multiple
lines for example) we send a single update only. Spice server has an
easier job now: The dependency tree for display operations which spice
server maintains for lazy rendering is alot smaller now. Spice server's
image compression probably works better too with the larger image blits.
Net effect: framebuffer console @ qxldrmfb is an order of magnitude
faster now.

Single channel LVDS maxes out at 112 MHz. The 15" pre-retina models
shipped with 1440x900 (106 MHz) by default or 1680x1050 (119 MHz)
as a BTO option, both versions used dual channel LVDS even though
the smaller one would have fit into a single channel.
Notes:
Bug report showing that the MacBookPro8,2 with 1440x900 uses dual
channel LVDS (this lead to it being hardcoded in intel_lvds.c by
Daniel Vetter with commit 618563e3945b9d0864154bab3c607865b557cecc):
https://bugzilla.kernel.org/show_bug.cgi?id=42842
If i915.lvds_channel_mode=2 is missing even though the machine needs
it, every other vertical line is white and consequently, only the left
half of the screen is visible (verified by myself on a MacBookPro9,1).
Forum posting concerning a MacBookPro6,2 with 1440x900, author is
using i915.lvds_channel_mode=2 on the kernel command line, proving
that the machine uses dual channels:
https://bbs.archlinux.org/viewtopic.php?id=185770
Chi Mei N154C6-L04 with 1440x900 is a replacement panel for all
MacBook Pro "A1286" models, and that model number encompasses the
MacBookPro6,2 / 8,2 / 9,1. Page 17 of the panel's datasheet shows it's
driven with dual channel LVDS:
http://www.ebay.com/itm/-/400690878560http://www.everymac.com/ultimate-mac-lookup/?search_keywords=A1286http://www.taopanel.com/chimei/datasheet/N154C6-L04.pdf
Those three 15" models, MacBookPro6,2 / 8,2 / 9,1, are the only ones
with i915 graphics and dual channel LVDS, so that list should be
complete. And the 8,2 is already in intel_lvds.c.
Possible motivation to use dual channel LVDS even on the 1440x900
models: Reduce the number of different parts, i.e. use identical logic
boards and display cabling on both versions and the only differing
component is the panel.

Single channel LVDS maxes out at 112 MHz, anything above must be dual

(193 MHz), plus those 15" pre-retina models which had a resolution
of 1680x1050 (119 MHz) as a BTO option.

This breaks under the vblank timestamp cleanup patch
by Daniel Vetter. Also it is pointless to return anything
but zero (or any other constant) if the function doesn't
actually query a hw vblank counter. The bogus return of
the current drm vblank counter via direct readout or via
drm_vblank_count() is found in many of the new kms drivers,
but it does exactly nothing different from returning any
arbitrary constant - it's a no operation.
Let's simply return 0 - Easy and fast.

Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.18, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.
v2: Rebased on top of Daniel Vetter's fixup and documentation
patch for timestamp updates. Drop request for stable kernel
backport as this would be more difficult, unless the original
patch would get applied to stable kernels.

For a kms driver to support immediate disable of vblank
irq's reliably without introducing off by one errors or
other mayhem for clients, it must not only support a
hardware vblank counter query, but also high precision
vblank timestamping, so vblank count and timestamp can be
instantaneously reinitialzed to valid values. Additionally
the exposed hardware counter must behave as if it is
incrementing at leading edge of vblank to avoid off by
one errors during reinitialization of the counter while
the display happens to be inside or close to vblank.
Check during drm_vblank_init that a driver which claims to
be capable of vblank_disable_immediate at least supports
high precision timestamping and prevent use of instant
disable if that isn't present as a minimum requirement.
v2: Changed from DRM_ERROR to DRM_INFO and made message

This was a bit too much cargo-culted, so lets make it solid:
- vblank->count doesn't need to be an atomic, writes are always done
under the protection of dev->vblank_time_lock. Switch to an unsigned
long instead and update comments. Note that atomic_read is just a
normal read of a volatile variable, so no need to audit all the
read-side access specifically.
- The barriers for the vblank counter seqlock weren't complete: The
read-side was missing the first barrier between the counter read and
the timestamp read, it only had a barrier between the ts and the
counter read. We need both.
- Barriers weren't properly documented. Since barriers only work if
you have them on boths sides of the transaction it's prudent to
reference where the other side is. To avoid duplicating the
write-side comment 3 times extract a little store_vblank() helper.
In that helper also assert that we do indeed hold
dev->vblank_time_lock, since in some cases the lock is acquired a
few functions up in the callchain.
Spotted while reviewing a patch from Chris Wilson to add a fastpath to
the vblank_wait ioctl.
v2: Add comment to better explain how store_vblank works, suggested by
Chris.
v3: Peter noticed that as-is the 2nd smp_wmb is redundant with the
implicit barrier in the spin_unlock. But that can only be proven by
auditing all callers and my point in extracting this little helper was
to localize all the locking into just one place. Hence I think that
additional optimization is too risky.
