Subject: drm/i915: enable irqs earlier when resuming
|
||||
|
||||
From: Daniel Vetter <daniel.vetter@ffwll.ch>
|
||||
|
||||
commit 15239099d7a7a9ecdc1ccb5b187ae4cda5488ff9 upstream.
|
||||
|
||||
We need it to restore the ilk rc6 context, since the gpu wait no
|
||||
requires interrupts. But in general having interrupts around should
|
||||
help in code sanity, since more and more stuff is interrupt driven.
|
||||
|
||||
This regression has been introduced in

||||

||||

|
||||
drm/i915: Rearrange code to only have a single method for waiting upon the ring
|
||||
|
||||
Like in the driver load code we need to make sure that hotplug
|
||||
interrupts don't cause havoc with our modeset state, hence block them
|
||||
with the existing infrastructure. Again we ignore races where we might
|
||||
loose hotplug interrupts ...
|
||||
|
||||
Note that the driver load part of the regression has already been
|
||||
fixed in

||||

||||

drm/i915: reorder setup sequence to have irqs for output setup
|
||||
|
||||
v2: Add a note to the commit message about which patch fixed the
|
||||
driver load part of the regression. Stable kernels need to backport
|
||||
both patches.

Subject: drm/i915: reorder setup sequence to have irqs for output setup
|
||||
|
||||
From: Daniel Vetter <daniel.vetter@ffwll.ch>
|
||||
|
||||
commit 52d7ecedac3f96fb562cb482c139015372728638 upstream.
|
||||
|
||||
Otherwise the new&shiny irq-driven gmbus and dp aux code won't work that
|
||||
well. Noticed since the dp aux code doesn't have an automatic fallback
|
||||
with a timeout (since the hw provides for that already).
|
||||
|
||||
v2: Simple move drm_irq_install before intel_modeset_gem_init, as
|
||||
suggested by Ben Widawsky.
|
||||
|
||||
v3: Now that interrupts are enabled before all connectors are fully
|
||||
set up, we might fall over serving a HPD interrupt while things are
|
||||
still being set up. Instead of jumping through massive hoops and
|
||||
complicating the code with a separate hpd irq enable step, simply
|
||||
block out the hotplug work item from doing anything until things are
|
||||
in place.
|
||||
|
||||
v4: Actually, we can enable hotplug processing only after the fbdev is
|
||||
fully set up, since we call down into the fbdev from the hotplug work
|
||||
functions. So stick the hpd enabling right next to the poll helper
|
||||
initialization.
|
||||
|
||||
v5: We need to enable irqs before intel_modeset_init, since that
|
||||
function sets up the outputs.
|
||||
|
||||
v6: Fixup cleanup sequence, too.
