The pipe is off at that point in time, so a vblank wait is simply a
50ms wait. Caught by Jesse's verbose "make vblank wait timeouts WARN"
patch. We've probably had a few versions of this float around already.
To document assumptions put a pipe assert into the same place. And
also add a posting read.
If we ever decide to update the eld and infoframes while the pipe is
already on (e.g. for fastboot) then there's lots of work to do. So
better properly document all the hidden assumptions.

BIT_WORD() truncates rather than rounds, so the loops in
syncpt_thresh_isr() and _host1x_intr_disable_all_syncpt_intrs() use <=
rather than < in an attempt to process the correct number of registers
when rounding of the conversion of count of bits to count of words is
necessary. However, when rounding isn't necessary because the value is
already a multiple of the divisor (as is the case for all values of
nb_pts the code actually sees), this causes one too many registers to
be processed.
Solve this by using and explicit DIV_ROUND_UP() call, rather than
BIT_WORD(), and comparing with < rather than <=.

With the recent primary-plane changes for drm, the primary plane's
framebuffer needs to be ref counted the same way as for
non-primary-planes. This was not done by the omapdrm driver, which
caused the ref count to drop to 0 too early, causing problems.
This patch moves the fb unref and ref from omap_plane_update to
omap_plane_mode_set. This way the fb refs are updated for both primary
and non-primary cases, as omap_plane_update calls omap_plane_mode_set.

omap_crtc->old_fb is used to check whether the previous page flip has completed
or not. However, it's never initialized to anything, so it's always NULL. This
results in the check to always succeed, and the page_flip to proceed.
Initialize old_fb to the fb that we intend to flip to through page_flip, and
therefore prevent a future page flip to proceed if the last one didn't
complete.

A waiter of the type OMAP_GEM_READ should wait for a buffer to be completely
written, and only then proceed with reading it. A similar logic applies for
waiters with OMAP_GEM_WRITE flag.
Currently the function is_waiting() waits on the read_complete/read_target
counts in the sync object.
This should be the other way round, as a reader should wait for users who are
'writing' to this buffer, and vice versa.
Make readers of the buffer(OMAP_GEM_READ) wait on the write counters, and
writers to the buffer(OMAP_GEM_WRITE) wait on the read counters in is_waiting()

At the moment the omap_crtc_pre_apply() handles the enabling, disabling
and configuring of encoders and panels separately from the CRTC (i.e.
the overlay manager).
However, this doesn't work correctly. The encoder driver has to be in
control of its video input (i.e. the crtc) for correct operation.
This problem causes bugs with (at least) HDMI: the HDMI encoder supplies
pixel clock for DISPC, and DISPC supplies video stream for HDMI. The
current code first enables the HDMI encoder, and CRTC after that.
However, the encoder expects the video stream to start during the
encoder's enable, and if it doesn't, there will be sync lost errors.
The encoder enables its video source by calling src->enable(), and this
call goes to omapdrm (omap_crtc_enable), but omapdrm doesn't do anything
in that function. Similarly for disable, which goes to
omap_crtc_disable().
This patch moves the code to setup and enable/disable the crtc to
omap_crtc_enable. and omap_crtc_disable().

At module unload, omap_fbdev_free() gets called which releases the
framebuffers. However, the framebuffers are still used by crtcs, and
will be released only later at vsync. The driver doesn't wait for this,
and goes on to release the rest of the resources, which often
causes a crash.
This patchs adds a omap_crtc_flush() function which waits until the crtc
has finished with its apply queue and page flips.
The function utilizes a simple polling while-loop, as the performance is
not an issue here.

At the moment the DMM driver is never unregistered, even if it's
registered in the omapdrm module's init function. This means we'll get
errors when reloading the omapdrm module.
Fix this by unregistering the DMM driver properly, and also change the
module init to fail if DMM driver cannot be registered, simplifying the
unregister path as we don't need to keep the state whether we registered

At the moment it's quite easy to get the following errors when the HDMI
output is enabled or disabled:
[drm:omap_crtc_error_irq] *ERROR* tv: errors: 00008000
The reason for the errors is that the omapdrm driver doesn't properly
handle the sync-lost irqs that happen when enabling the DIGIT crtc,
which is used for HDMI and analog TV. The driver does disable the
sync-lost irq properly, but it fails to wait until the output has been
fully enabled (i.e. the first vsync), so the sync-lost errors are still
seen occasionally.
This patch makes the omapdrm act the same way as the omapfb does:
- When enabling a display, we'll wait for the first vsync.
- When disabling a display, we'll wait for framedone if available, or
odd and even vsyncs.
These changes make sure the output is fully enabled or disabled at the
end of the function.

If we always initialize kref for the context, even if we are using fake
contexts for hangstats when there is no hw support, we can forgo the
dance to dereference the ctx->obj and inspect whether we are permitted
to use kref inside i915_gem_context_reference() and _unreference().
My ulterior motive here is to improve the debugging of a use-after-free
of ctx->obj. This patch avoids the dereference here and instead forces
the assertion checks associated with kref.
v2: Refactor the fake contexts to being even more like the real
contexts, so that there is much less duplicated and special case code.
v3: Tweaks.
v4: Tweaks, minor.

Some machines use an external EC for controlling the backlight. Info

if no PWM backlight is available or supported according to VBT. The
acpi_backlight interface appears to work for the EC control.
In most cases there has been no harm done, but it looks like there are
machines out there that have both an EC and our PWM line connected to
the same wire. This, obviously, does not end well.

This reverts commit 4b28a1f3ef55a3b0b68dbab1fe6dbaf18e186710.
This patch duct-tapes over some issue in the current bdw rps patches
which must wait with enabling rc6/rps until the very first batch has
been submitted by userspace.
But those patches aren't merged yet, and for upstream we need to have
an in-kernel emission of the very first batch. I shouldn't have
merged this patch so let's revert it again.
Also Imre noticed that even when rps is set up normally there's a
small window (due to the 1s delay of the async rps init work) where we
could runtime suspend already and blow up all over the place. Imre has
a proper fix to block runtime pm until the rps init work has
successfully completed.
