The parallel-display driver used an undocumented, non-standard property
"fsl,panel" to optionally associate with a drm_panel device. This patch
fixes the driver to use the same OF graph bindings as the LDB driver
instead:
parallel-display {
compatible = "fsl,imx-parallel-display";
...
port@1 {
reg = <1>;
parallel_out: endpoint {
remote_endpoint = <&panel_in>;
};
};
};
panel {
...
port {
panel_in: endpoint {
remote-endpoint = <¶llel_out>;
};
};
};

This fbdev restore mode was another corner case that was now
calling frontbuffer flip and flush and making we miss
screen updates with PSR enabled.
So let's also add the invalidate hack here while we don't have
a reliable dirty fbdev op.
v2: As pointed by Paulo: removed seg fault risk, used fb_helper
when possible and put brackets on if.

drm/i915: Unconditionally do fb tracking invalidate in set_domain
Note that even before this commit it wasn't perfect since the
invalidate was omitted if the fbcon was already in the GTT domain,
which it usually was.
Since we are also invalidating in other fbdev cases this one
was masked here. At least until now that I found this corner
case: On boot with plymouth doing a splash screen
when returning to the console frontbuffer wans't being invalidated
causing missed screen updates with PSR enabled.
So this patch fixes this issue.
v2: Make invalidate directly and unconditionally and
fix commit message indicating the set_domain fix
as pointed out by Daniel.
v3: Remove unecessary if(obj) added by mistake

Idle frames the number of identical frames needed
before panel can enter PSR.
There are some panels that requires up to minimum of 4 idle
frames available on the market. For these cases usually
VBT should be used to configure the number of idle frames,
but unfortunately this isn't always true and VBT isn't being
set at all.
Let's trust VBT when it is set + 1 and use minimum of 4 + 1
when VBT isn't set. "+1" covers the "of-by-one" case.

By Spec we should only mask memup and hotplug detection
for hardware tracking cases. However we always masked
LPSP because with power well always enabled on audio
PSR was never being activated and residency was always
zeroed.
Apparently audio driver is tying power well management
and runtime PM for some reason. But with audio runtime
PM working or with audio completely out of picture
we should remove this mask, otherwise we have a high
risk of miss screen updates as faced by Matthew.
WARNING: With this patch if snd_intel_hda driver is
running and not releasing power well properly PSR will
constant Exit and Performance Counter will be 0.
But the best thing of this patch is that with one more
HW tracking working the risks of missed blank screen
are minimized at most.
This affects just core platforms where PSR exit are also
helped by HW tracking: Haswell, Broadwell and Skylake
for now.
v2: Fix commit message explanation. It has nothing to do
with runtime PM on i915 as previously advertised.

Let's do a frontbuffer flush on dirty fb.
To be used for DIRTYFB drm ioctl.
This patch solves the biggest PSR known issue, that is
missed screen updates during boot, mainly when there is a splash
screen involved like Plymouth.
Previously PSR was being invalidated by fbdev and Plymounth
was taking control with PSR yet invalidated and could get screen
updates normally. However with some atomic modeset changes
Pymouth modeset over ioctl was now causing frontbuffer flushes
making PSR gets back to work while it cannot track the
screen updates and exit properly.
By adding this flush on dirtyfb we properly track frontbuffer
writes and properly exit PSR.
Actually all mmap_wc users should call this dirty callback
in order to have a proper frontbuffer tracking.
In the future it can be extended to return 0 if the whole
screen has being flushed or the number of rects flushed
as Chris suggested.
v2: Remove ORIGIN_FB_DIRTY and use ORIGIN_GTT instead since dirty
callback is just called after few screen updates and not on
everyone as pointed by Daniel.
v3: Use flush instead of invalidate since flush means
invalidate + flush and dirty means drawn had finished and
it can be flushed.
v4: Remove PSR from subject since it is purely frontbuffer tracking
change and that can be useful for FBC as well.

Since flush actually means invalidate + flush we need to force psr
exit on PSR flush.
On Core platforms there is no way to disable hw tracking and
do the pure sw tracking so we simulate it by fully disable psr and
reschedule a enable back.
So a good idea is to minimize sequential disable/enable in cases we
know that HW tracking like when flush has been originated by a flip.
Also flip had just invalidated it already.
It also uses origin to minimize the a bit the amount of
disable/enabled, mainly when flip already had invalidated.
With this patch in place it is possible to do a flush on dirty areas
properly in a following patch.
v2: Remove duplicated exit on HSW+Sprites as pointed out by Paulo.

The old style of memory interleaving swizzled upto the end of the
first even bank of memory, and then used the remainder as unswizzled on
the unpaired bank - i.e. swizzling is not constant for all memory. This
causes problems when we try to migrate memory and so the kernel prevents
migration at all when we detect L-shaped inconsistent swizzling.
However, this issue also extends to userspace who try to manually detile
into memory as the swizzling for an individual page is unknown (it
depends on its physical address only known to the kernel), userspace
cannot correctly swizzle objects.
v2: Mark the global swizzling as unknown rather than adjust the value
reported to userspace.

Trying to resolve issues with missed vblanks and impossible
values inside delivered kms pageflip completion events showed
that radeon's irq handling sometimes doesn't handle valid irqs,
but silently skips them. This was observed for vblank interrupts.
Although those irqs have corresponding events queued in the gpu's
irq ring at time of interrupt, and therefore the corresponding
handling code gets triggered by these events, the handling code
sometimes silently skipped processing the irq. The reason for those
skips is that the handling code double-checks for each irq event if
the corresponding irq status bits in the irq status registers
are set. Sometimes those bits are not set at time of check
for valid irqs, maybe due to some hardware race on some setups?
The problem only seems to happen on some machine + card combos
sometimes, e.g., never happened during my testing of different PC
cards of the DCE-2/3/4 generation a year ago, but happens consistently
now on two different Apple Mac cards (RV730, DCE-3, Apple iMac and
Evergreen JUNIPER, DCE-4 in a Apple MacPro). It also doesn't happen
at each interrupt but only occassionally every couple of
hundred or thousand vblank interrupts.
This results in XOrg warning messages like
"[ 7084.472] (WW) RADEON(0): radeon_dri2_flip_event_handler:
Pageflip completion event has impossible msc 420120 < target_msc 420121"
as well as skipped frames and problems for applications that
use kms pageflip events or vblank events, e.g., users of DRI2 and
DRI3/Present, Waylands Weston compositor, etc. See also
https://bugs.freedesktop.org/show_bug.cgi?id=85203
After some talking to Alex and Michel, we decided to fix this
by turning the double-check for asserted irq status bits into a
warning. Whenever a irq event is queued in the IH ring, always
execute the corresponding interrupt handler. Still check the irq
status bits, but only to log a DRM_DEBUG message on a mismatch.
This fixed the problems reliably on both previously failing
cards, RV-730 dual-head tested on both crtcs (pipes D1 and D2)
and a triple-output Juniper HD-5770 card tested on all three
available crtcs (D1/D2/D3). The r600 and evergreen irq handling
is therefore tested, but the cik an si handling is only compile
tested due to lack of hw.

wa_ctx_emit() depends on the name of a local variable; if the name of that
variable is changed then we get compile errors. In this case it is unlikely
to be changed as this macro is only used in this set of functions but
Kernel coding guidelines doesn't recommend doing this. It was my mistake
as I should have corrected it at the beginning but missed so correct
this before there are more usages of this macro (Bob Beckett).

Chapter 12, "Things to avoid when using macros", point 2):
"
2) macros that depend on having a local variable with a magic name:
#define FOO(val) bar(index, val)

code and it's prone to breakage from seemingly innocent changes.
"
v2: Optimization to avoid multiple evaluation of 'index' in the macro.

them into a single condition and remove multiple WARN_ON checks (Chris).

We also don't need to update any other plane check functions since we

I'm getting tired of adding "struct drm_device *dev = dev_priv->dev"
everywhere.
If I get a NACK here I'll propose the opposite: convert all the
functions that currently take dev_priv to take dev.

When rotated and partial views were added no one spotted the resume
path which assumes only one GGTT VMA per object and hence is now
skipping rebind of alternative views.

legacy setcrtc ioctl does take a 32 bit value which might indeed
overflow
the checks of crtc_req->x > INT_MAX and crtc_req->y > INT_MAX aren't
needed any more with this
v2: -polish the annotation according to Daniel's comment

Rather than (incompletely [0]) re-implementing drm_gem_mmap() and
drm_gem_mmap_obj() helpers, call them directly from the rockchip mmap
routines.
Once the core functions return successfully, the rockchip mmap routines
can still use dma_mmap_attrs() to simply mmap the entire buffer.
[0] Previously, we were performing the mmap() without first taking a
reference on the underlying gem buffer. This could leak ptes if the gem
object is destroyed while userspace is still holding the mapping.

After the register save/restore code is gone there's just one user
left and it just obfuscates that one. Remove it.

Since that's really what we want to test for. Note remove the gen5
case doesn't change anything: In intel_setup_outputs ilk is handled
already in the HAS_PCH_SPLIT case, and the register save/restore code
touches registers which simply doesn't exist anymore at all.
v2: Drop UMS parts.
v3: Update commit message to reflect that the reg save/restore code is
gone (Ville).

It's probably allowed to leave old_fb set to garbage when unlocking,
but to prevent undefined behavior unset it just in case.
Also crtc_state->event could be NULL on memory allocation failure,
in which case event_space is increased for no reason.
Note: Contains some general simplification of the cleanup code too.

The legacy page_flip driver entry point is the only one left which
requires drivers to update plane->fb themselves. All the other entry
hooks will patch things up for the driver as needed since no one seems
to reliable get this right, see e.g. drm_mode_set_config_internal or
the plane->fb/old_fb handling in drm_mode_atomic_ioctl.
Therefore unify things, which allows us to ditch a TODO from
drm_atomic_helper_page_flip.
This should also help the atomic transition in i915 since we keep a
bit of legacy cruft only around because of this special behaviour in
->page_flip.

Follow the correct pipe vs port disable sequence for the PCH LVDS
ports, ie. disable the port after the pipe.
Other PCH port were already converted in the following commits:
1ea56e269e136544c0a76dc831c5edc27c47cb3c drm/i915: Disable CRT port after pipe on PCH platforms

a4790cec3adf5eec91f397b1884706a71c70730f drm/i915: Disable HDMI port after the pipe on PCH platforms
08aff3fe26ae7a0d6f302ac2e1b7e2eb9933cd42 drm/i915: Move DP port disable to post_disable for pch platforms
but LVDS was forgotten.
