Michel Thierry 088e0df402 drm/i915/gtt: Allow >= 4GB offsets in X86_32
Similar to commit c44ef60e43 ("drm/i915/gtt:
Allow >= 4GB sizes for vm"), i915_gem_obj_offset and i915_gem_obj_ggtt_offset
return an unsigned long, which in only 4-bytes long in 32-bit kernels.

Change return type (and other related offset variables) to u64.

Since Global GTT is always limited to 4GB, this change would not be required
in i915_gem_obj_ggtt_offset, but this is done for consistency.

v2: Remove unnecessary offset variable in do_pin, as we already have
    vma->node.start (Chris).
    Update GGTT offset too (Tvrtko).

Daniel Vetter c50bfd08d6 drm/fbdev: Return -EBUSY when oopsing
Trying to do anything with kms drivers when oopsing has become a
failing proposition. But since we can end up in the fbdev code simply
due to the console unblanking that's done unconditionally just
removing our panic handler isn't enough. We need to block all fbdev
callbacks when oopsing.

There was already one in the blank handler, but it failed silently.
That makes it impossible for drivers (like i915) who subclass these
functions to figure this out.

Instead consistently return -EBUSY so that everyone knows that we
really don't want to be bothered right now. This also allows us to
remove a pile of FIXMEs from the i915 fbdev code (since due to the
failure code they now won't attempt to grab dangerous locks any more).

Maarten Lankhorst 5c1e342619 drm/i915: Readout initial hw mode.
drm/i915: Readout initial hw mode, v2.

Atomic requires a mode blob when crtc_state->enable is true, or
you get a huge warn_on.

With a few tweaks the mode we read out from hardware could be used
as the real mode without a modeset, but this requires too much
testing, so for now force a modeset the first time the mode blob's
updated.

This preserves the old behavior, because previously we never set
the initial mode, which always meant that a modeset happened
when the mode was first set.

Changes since v1:
- Add a description in intel_modeset_readout_hw_state of how the
  recalculation is done.

    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

John Harrison 91af127fd7 drm/i915: Update i915_gem_object_sync() to take a request structure
The plan is to pass requests around as the basic submission tracking structure
rather than rings and contexts. This patch updates the i915_gem_object_sync()
code path.

v2: Much more complex patch to share a single request between the sync and the
page flip. The _sync() function now supports lazy allocation of the request
structure. That is, if one is passed in then that will be used. If one is not,
then a request will be allocated and passed back out. Note that the _sync() code
does not necessarily require a request. Thus one will only be created until
certain situations. The reason the lazy allocation must be done within the
_sync() code itself is because the decision to need one or not is not really
something that code above can second guess (except in the case where one is
definitely not required because no ring is passed in).

The call chains above _sync() now support passing a request through which most
callers passing in NULL and assuming that no request will be required (because
they also pass in NULL for the ring and therefore can't be generating any ring
code).

The exeception is intel_crtc_page_flip() which now supports having a request
returned from _sync(). If one is, then that request is shared by the page flip
(if the page flip is of a type to need a request). If _sync() does not generate
a request but the page flip does need one, then the page flip path will create
its own request.

v3: Updated comment description to be clearer about 'to_req' parameter (Tomas
Elf review request). Rebased onto newer tree that significantly changed the
synchronisation code.

v4: Updated comments from review feedback (Tomas Elf)

Rodrigo Vivi 03e515f7f8 drm/i915: Make sure we invalidate frontbuffer on fbcon.
There are some cases like suspend/resume or dpms off/on sequences
that can flush frontbuffer bits. In these cases features that relies

So, let's make sure we also invalidate frontbuffer on fbdev blank.

one so let's make sure frontbuffer bits gets invalidate here instead of
on random write operations that doesn't garantee we track all frontbuffer

Notes:
a) this reworks irq handling for DP MST ports, so that we can
avoid the mode config locking in the current hpd handlers, as
we need to process up/down msgs at a better time.

Changes since v0.1:
use PORT_PCH_HOTPLUG to detect short vs long pulses
add a workqueue to deal with digital events as they can get blocked on the
main workqueue beyong mode_config mutex
fix a bunch of modeset checker warnings
acks irqs in the driver
cleanup the MST encoders

Changes since v0.2:

move around bring up and tear down to fix DPMS on/off
use path properties.

Changes since v0.3:

more state checker fixes
irq handling improvements
fbcon handling support
improved reference counting of link - fixes redocking.

Changes since v0.4:
handle gpu reset hpd reinit without oopsing
check link status on HPD irqs
fix suspend/resume

Changes since v0.5:
use proper functions to get max link/lane counts
fix another checker backtrace - due to connectors disappearing.
set output type in more places fro, unknown->displayport
don't talk to devices if no HPD asserted
check mst on short irqs only

Thierry Reding 10a2310265 drm: Introduce drm_fb_helper_prepare()
To implement hotplug detection in a race-free manner, drivers must call
drm_kms_helper_poll_init() before hotplug events can be triggered. Such
events can be triggered right after any of the encoders or connectors
are initialized. At the same time, if the drm_fb_helper_hotplug_event()
helper is used by a driver, then the poll helper requires some parts of
the FB helper to be initialized to prevent a crash.

At the same time, drm_fb_helper_init() requires information that is not
necessarily available at such an early stage (number of CRTCs and
connectors), so it cannot be used yet.

Add a new helper, drm_fb_helper_prepare(), that initializes the bare
minimum needed to allow drm_kms_helper_poll_init() to execute and any
subsequent hotplug events to be processed properly.

X could end up putting the fbcon fb into other domains, e.g.
for smooth take-overs. Also we want this for accurate frontbuffer
tracking: The set_config is an implicit flush and will re-enable
psr and similar features, so we need to bring the bo back into
the gtt domain.

Chris Wilson afba0b5a22 drm/i915: Use the first mode if there is no preferred mode in the EDID
This matches the algorithm used by earlier kernels when selecting the
mode for the fbcon. And only if there is no modes at all, do we fall
back to using the BIOS configuration. Seamless transition is still
preserved (from the BIOS configuration to ours) so long as the BIOS has
also chosen what we hope is the native configuration.

use the CRTC and connector ids. These are much harder for us to

case). Similarly, we want to manually print the mode size rather than
rely on mode->name being set.

Daniel Vetter 7e696e4cad drm/i915: ignore bios output config if not all outputs are on
Both Ville and QA rather immediately complained that with the new
initial_config logic from Jesse not all outputs get enabled. Since the
fbdev emulation pretty much tries to always enable as many outputs as
possible (it even has hotplug handling and all that) fall back if more
outputs could have been enabled.

v2: Fix up my confusion about what enabled means - it's passed from
the fbdev helper, we need to check for a non-zero connector->encoder
link. Spotted by Ville.

v3: Add some debug output as requested by Jesse for debugging fallback
issues.
