            drm/i915: Move to atomic plane helpers (v9)

one of the changes was to call intel_plane_destroy_state() while tearing
down a plane to prevent leaks when unloading the driver.  That made
sense when the patches were first written, but before they were merged,

            drm: Free atomic state during cleanup

had already landed, which made this the responsibility of the DRM core.
The result was that we were kfree()'ing the state twice, and also
possibly double-unref'ing a framebuffer, leading to memory corruption
when the driver was unloaded.

The fix is to simply not try to cleanup the state in the i915 teardown
code now that the core handles this for us.

drm/exynos: unify plane update on exynos_update_plane()

We can safely use the exynos_update_plane() to update the plane
framebuffer for both the overlay and primary planes.

Note that this patch removes a call to manager->ops->commit() in
exynos_drm_crtc_mode_set_commit(). The commit() call is used only by the
fimd driver to set underlying timings and need only in full modeset
operations. For plane update only win_commit is needed.

9 years agodrm/probe-helper: clamp unknown connector status in the poll work
Daniel Vetter [Wed, 21 Jan 2015 07:45:22 +0000 (08:45 +0100)]
drm/probe-helper: clamp unknown connector status in the poll work

On some chipset we try to avoid possibly invasive output detection
methods (like load detect which can cause flickering elsewhere) in the
output poll work. Drivers could hence return unknown when a previous
full ->detect call returned a different state.

This change will generate a hotplug event, forcing userspace to do a
full scan. This in turn updates the connector->status field so that we
will _again_ get a state change when the hotplug work re-runs in 10
seconds.

To avoid this ping-pong loop detect this situation and clamp the
connector state to the old value.

Patch is inspired by a patch from Knut Peterson. Knut's patch
completely ignored connector state changes if either the old or new
status was unknown, which seemed to be a bit too agressive to me.

v2: Rebased onto the drm_probe_helper.c extraction.

9 years agodrm/probe-helper: don't lose hotplug event
Daniel Vetter [Wed, 21 Jan 2015 07:45:21 +0000 (08:45 +0100)]
drm/probe-helper: don't lose hotplug event

There's a race window (small for hpd, 10s large for polled outputs)
where userspace could sneak in with an unrelated connnector probe
ioctl call and eat the hotplug event (since neither the hpd nor the
poll code see a state change).

To avoid this, check whether the connector state changes in all other
->detect calls (in the current helper code that's only probe_single)
and if that's the case, fire off a hotplug event. Note that we can't
directly call the hotplug event handler, since that expects that no
locks are held (due to reentrancy with the fb code to update the kms
console).

Also, this requires that drivers using the probe_single helper
function set up the poll work. All current drivers do that already,
and with the reworked hpd handling there'll be no downside to
unconditionally setting up the poll work any more.

v2: Review from Rob Clark
- Don't bail out of the output poll work immediately if it's disabled
  to make sure we deliver the delayed hoptplug events. Instead just
  jump to the tail.
- Don't scheduel the work when it's not set up. Would be a driver bug
  since using probe helpers for anything dynamic without them
  initialized makes them all noops.

driver from nouveau_ to nvkm_, in preparation for splitting the module
into two down the track.  Also switched to NVIDIA's unit and chipset
names at the same time.  Despite the massive amount of code touch, the
commits should be safe as objdump was used to verify nothing got
changed accidentally in the renames.

Aside from that, not much in this first pull request:
- nouveau_platform.ko for GK20A was merged into nouveau.ko
- GK20A dynamic reclocking support
- no more vt-switches across suspend/resume
- changed output scaling policy.  if the mode comes from the display's
edid, we program that directly rather than using the gpu to scale to
the panel's native mode.  this should address complaints of having to
jump through hoops for 24/120Hz modes etc
