[PATCH v2 00/14] drm/i915/fbc: Fix FBC for glk+

[PATCH v2 00/14] drm/i915/fbc: Fix FBC for glk+

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

CI got hopelessly confused with the v1 series so reposting in its
entirety.

I also slapped on an extra patch at the end which should hopefully
avoid the problems with FBC not getting enabled with fastboot.

[PATCH v2 01/14] drm/i915/fbc: Disable fbc by default on all glk+

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We're missing a workaround in the fbc code for all glk+ platforms
which can cause corruption around the top of the screen. So
enabling fbc by default is a bad idea. I'm not keen to backport
the w/a so let's start by disabling fbc by default on all glk+.
We'll lift the restriction once the w/a is in place.

[PATCH v2 04/14] drm/i915/fbc: Remove the FBC_RT_BASE setup for ILK/SNB

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We don't want to use the FBC hardware render tracking so let's not
enable it. To use the hw tracking properly we'd anyway need to
integrate this into the command submissing path as the register is
context saved, and if rendering happens via the ppgtt we'd have
to configure it with the ppgtt address instead of the ggtt address.
Easier to use software tracking instead.

Note that on pre-ilk we can't actually disable render tracking.
However we can't rely on it because it requires that DSPSURF to
match the render target address, and since we play tricks
with DSPSURF that may not be the case. Hence we shall rely on
software render tracking on all platforms.

[PATCH v2 06/14] drm/i915/fbc: Track plane visibility

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently the code (ab)uses cache->vma to indicate the plane
visibility. I want to nuke that so let's add a dedicated boolean
for this.

[Intel-gfx] [PATCH v2 06/14] drm/i915/fbc: Track plane visibility

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently the code (ab)uses cache->vma to indicate the plane
visibility. I want to nuke that so let's add a dedicated boolean
for this.

[PATCH v2 08/14] drm/i915/fbc: Make fence_id optional for i965gm

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

i965gm no longer needs the fence for scanout so we should be
do what we do for ctg+ and only configure a fence for FBC
when we have one.

In theory this should do nothing atm on account of
intel_fbc_can_activate() requiring the fence, but since
we do this for g4x+ let's do it for i965gm as well. We
may want to relax the requirements at some point and allow
FBC without a fence.

[Intel-gfx] [PATCH v2 08/14] drm/i915/fbc: Make fence_id optional for i965gm

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

i965gm no longer needs the fence for scanout so we should be
do what we do for ctg+ and only configure a fence for FBC
when we have one.

In theory this should do nothing atm on account of
intel_fbc_can_activate() requiring the fence, but since
we do this for g4x+ let's do it for i965gm as well. We
may want to relax the requirements at some point and allow
FBC without a fence.

[PATCH v2 11/14] drm/i915/fbc: Start using flip nuke

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The hardware automagically nukes the cfb on flip. We can use
that whenever the plane/crtc configuration doesn't change too
much. Let's hook that up.

We'll need this for glk+ since we need to introduce an extra
vblank wait after FBC disable. As we're currently disabling
FBC around all plane updates we'd slow them down by an extra
frame. Not a great user experience when your fps is always
capped at vrefres/2. With flip nuke we don't need the extra
vblank wait.

[Intel-gfx] [PATCH v2 11/14] drm/i915/fbc: Start using flip nuke

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The hardware automagically nukes the cfb on flip. We can use
that whenever the plane/crtc configuration doesn't change too
much. Let's hook that up.

We'll need this for glk+ since we need to introduce an extra
vblank wait after FBC disable. As we're currently disabling
FBC around all plane updates we'd slow them down by an extra
frame. Not a great user experience when your fps is always
capped at vrefres/2. With flip nuke we don't need the extra
vblank wait.

[PATCH v2 12/14] drm/i915/fbc: Wait for vblank after FBC disable on glk+

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

On glk+ the hardware gets confused if we disable FBC while
it's recompressing and we perform a plane update during the
same frame. The result is that top of the screen gets corrupted.

We can avoid that by giving the hardware enough time to finish
the FBC disable before we touch the plane registers. Ie. we need
an extra vblank wait after FBC disable.

[PATCH v2 14/14] drm/i915/fbc: Reallocate cfb if we need more of it

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The code assumes we can omit the cfb allocation once fbc
has been enabled once. That's nonsense. Let's try to
reallocate it if we need to.

The code is still a mess, but maybe this is enough to get
fbc going in some cases where it initially underallocates
the cfb and there's no full modeset to fix it up.

The code assumes we can omit the cfb allocation once fbc
has been enabled once. That's nonsense. Let's try to
reallocate it if we need to.

The code is still a mess, but maybe this is enough to get
fbc going in some cases where it initially underallocates
the cfb and there's no full modeset to fix it up.

Retested Asus E406MA, default parameters (fastboot=1) and now FBC is
marked enabled in i915_fbc_status.
I can't reproduce the visual corruption using my original tests
(interacting with GNOME gdm login screen, frantically scrolling text
inside gnome-terminal).

Tested-by: Daniel Drake <drake@endlessm.com>

[PATCH v3 12/14] drm/i915/fbc: Wait for vblank after FBC disable on glk+

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

On glk+ the hardware gets confused if we disable FBC while
it's recompressing and we perform a plane update during the
same frame. The result is that top of the screen gets corrupted.

We can avoid that by giving the hardware enough time to finish
the FBC disable before we touch the plane registers. Ie. we need
an extra vblank wait after FBC disable.

v2: Don't do the vblank wait if we never activated FBC in hw

For 1-11, 14

How would we get rid of the disable there? By triggering nukes at some
predefined interval? Doesn't sound all that great.

Not touching FBC on frontbuffer write at all, and forcing userspace to use the dirtyfb api. I think the whole implicit tracking should be removed.

Perhaps. Not sure userspace is ready for that though.

I guess the only long lasting frontbuffer invalidate is the
one from set_domain. Everything else is bounded and so we
know the flush is going to come in a somewhat timely manner.
So for those cases I guess we could perhaps skip the invalidate.

Hmm. Also looks like ORIGIN_GTT has been neutered and now
we treat everyting as ORIGIN_CPU. That's maybe not so great.
Should probably reinstate ORIGIN_GTT so we can actually benefit
from the hw gtt tracking. Or we just try to kill that off as well.

Also I wonder where is the flush counterpart to the invalidate
in i915_gem_object_prepare_write()?

Perhaps. Not sure userspace is ready for that though.

I guess the only long lasting frontbuffer invalidate is the
one from set_domain. Everything else is bounded and so we
know the flush is going to come in a somewhat timely manner.
So for those cases I guess we could perhaps skip the invalidate.

Hmm. Also looks like ORIGIN_GTT has been neutered and now
we treat everyting as ORIGIN_CPU. That's maybe not so great.
Should probably reinstate ORIGIN_GTT so we can actually benefit
from the hw gtt tracking. Or we just try to kill that off as well.

Also I wonder where is the flush counterpart to the invalidate
in i915_gem_object_prepare_write()?

We have to audit that DirtyFB is called on all gen9+ userspace, because FBC is only enabled by default on those platforms.

I know the modesetting ddx does, I believe xf86-video-intel as well. So it should be safe to do. We could hide the old behavior behind a kernel parameter for now for 1 or 2 releases,

so we can chicken out if needed.

HW tracking has been buggy for a long time, and is no longer available on current hw because of those bugs.

I'll probably enable it across the board once I get it fixed.

Which bugs? We still enable it on all platforms so I don't know what
you mean by it not being available.

Entire series pushed with Maarten's irc r-b for the rest (thanks).

I also tracked down the lag I'm seeing on my laptop. It's caused by
the intel ddx never issuing dirtyfb ioctls because it fails to
correctly detect the capability. I'll post fixes for that shortly.
I suspect it was working better before we got WC mmap because then
the hw gtt tracking should have dealt with it. But with WC mmap
that no longer works and we actually depend on dirtyfb to flush
things.
