commit b25b4427e9dfba073cf9bc86603956ed395eb6e3 upstream.
The intent was to only enable it by default for optimus, e.g. see the
runtime_idle callback. The suspend callback may be called directly, e.g.
as a result of nouveau_crtc_set_config.

commit 9fadb352ed73edd7801a280b552d33a6040c8721 upstream.
Only the render backends of the first shader engine were enabled. The others
were erroneously disabled. Enabling the other render backends improves
performance a lot.
Unigine Sanctuary on Bonaire:
Before: 15 fps
After: 90 fps
Judging from the fan noise, the GPU was also underclocked when the other
render backends were disabled, resulting in horrible performance. The fan is
a lot noisy under load now.

commit a885b3ccc74d8e38074e1c43a47c354c5ea0b01e upstream.
The GMCH_CTRL register (or MGCC in the spec) is at a different address
on Sandybridge, and the address to which we currently write to is
undefined. These stray writes appear to upset (hard hang) my Ivybridge
machine whilst it is in UEFI mode.
Note that the register is still marked as locked RO on Sandybridge, so
vgaarb is still dysfunctional.

commit 96b4026878d9dac71bd4c3d6e05c7fbb16a3e0aa upstream.
Currently, PC8 is enabled at modeset_global_resources, which is called
after intel_modeset_update_state. Due to this, there's a small race
condition on the case where we start enabling PC8, then do a modeset
while PC8 is still being enabled. The racing condition triggers a WARN
because intel_modeset_update_state will mark the CRTC as enabled, then
the thread that's still enabling PC8 might look at the data structure
and think that PC8 is being enabled while a pipe is enabled. Despite
the WARN, this is not really a bug since we'll wait for the
PC8-enabling thread to finish when we call modeset_global_resources.
The spec says the CRTC cannot be enabled when we disable LCPLL, so we
had a check for crtc->base.enabled. If we change to crtc->active we
will still prevent disabling LCPLL while the CRTC is enabled, and we
will also prevent the WARN above.
This is a replacement for the previous patch named
"drm/i915: get/put PC8 when we get/put a CRTC"

commit 4db080f9e93411c3c41ec402244da28e2bbde835 upstream.
As the rings may be processed and their requests deallocated in a
different order to the natural retirement during a reset,
/* Whilst this request exists, batch_obj will be on the
* active_list, and so will hold the active reference. Only when this
* request is retired will the the batch_obj be moved onto the
* inactive_list and lose its active reference. Hence we do not need
* to explicitly hold another reference here.
*/
is violated, and the batch_obj may be dereferenced after it had been
freed on another ring. This can be simply avoided by processing the
status update prior to deallocating any requests.

commit 6c719faca2aceca72f1bf5b1645c1734ed3e9447 upstream.
The update is horribly racy since it doesn't protect at all against
concurrent closing of the master fd. And it can't really since that
requires us to grab a mutex.
Instead of jumping through hoops and offloading this to a worker
thread just block this bit of code for the modesetting driver.
Note that the race is fairly easy to hit since we call the breadcrumb
function for any interrupt. So the vblank interrupt (which usually
keeps going for a bit) is enough. But even if we'd block this and only
update the breadcrumb for user interrupts from the CS we could hit
this race with kms/gem userspace: If a non-master is waiting somewhere
(and hence has interrupts enabled) and the master closes its fd
(probably due to crashing).
v2: Add a code comment to explain why fixing this for real isn't
really worth it. Also improve the commit message a bit.
v3: Fix the spelling in the comment.

commit acc240d41ea1ab9c488a79219fb313b5b46265ae upstream.
So apparently under ridiculous amounts of memory pressure we can get
into trouble in do_switch when we try to move the old hw context
backing storage object onto the active lists.
With list debugging enabled that usually results in us chasing a
poisoned pointer - which means we've hit upon a vma that has been
removed from all lrus with list_del (and then deallocated, so it's a
real use-after free).
Ian Lister has done some great callchain chasing and noticed that we
can reenter do_switch:
i915_gem_do_execbuffer()
i915_switch_context()
do_switch()
from = ring->last_context;
i915_gem_object_pin()
i915_gem_object_bind_to_gtt()
ret = drm_mm_insert_node_in_range_generic();
// If the above call fails then it will try i915_gem_evict_something()
// If that fails it will call i915_gem_evict_everything() ...
i915_gem_evict_everything()
i915_gpu_idle()
i915_switch_context(DEFAULT_CONTEXT)
Like with everything else where the shrinker or eviction code can
invalidate pointers we need to reload relevant state.
Note that there's no need to recheck whether a context switch is still
required because:
- Doing a switch to the same context is harmless (besides wasting a
bit of energy).
- This can only happen with the default context. But since that one's
pinned we'll never call down into evict_everything under normal
circumstances. Note that there's a little driver bringup fun
involved namely that we could recourse into do_switch for the
initial switch. Atm we're fine since we assign the context pointer
only after the call to do_switch at driver load or resume time. And
in the gpu reset case we skip the entire setup sequence (which might
be a bug on its own, but definitely not this one here).
Cc'ing stable since apparently ChromeOS guys are seeing this in the
wild (and not just on artificial stress tests), see the reference.
Note that in upstream code doesn't calle evict_everything directly
from evict_something, that's an extension in this product branch. But
we can still hit upon this bug (and apparently we do, see the linked
backtraces). I've noticed this while trying to construct a testcase
for this bug and utterly failed to provoke it. It looks like we need
to driver the system squarly into the lowmem wall and provoke the
shrinker to evict the context object by doing the last-ditch
evict_everything call.
Aside: There's currently no means to get a badly-fragmenting hw
context object away from a bad spot in the upstream code. We should
fix this by at least adding some code to evict_something to handle hw
contexts.

commit 0d1430a3f4b7cfd8779b78740a4182321f3ca7f3 upstream.
Inorder to serialise the closing of the file descriptor and its
subsequent release of client requests with i915_gem_free_request(), we
need to hold the struct_mutex in i915_gem_release(). Failing to do so
has the potential to trigger an OOPS, later with a use-after-free.

commit 027476642811f8559cbe00ef6cc54db230e48a20 upstream.
Some lower level things get angry if we don't have modeset locks
during intel_modeset_setup_hw_state(). Actually the resume and
lid_notify codepaths alreday hold the locks, but the init codepath
doesn't, so fix that.
Note: This slipped through since we only disable pipes if the
plane/pipe linking doesn't match. Which is only relevant on older
gen3 mobile machines, if the BIOS fails to set up our preferred
linking.

commit f60711666bcab6df2c6c91d851e07ed54088453c upstream.
The global integrated clock source bit resides in DPLL B on VLV, but we
were treating it as a per-pipe resource. It needs to be set whenever
any PLL is active, so pull setting the bit out of vlv_update_pll and
into vlv_enable_pll. Also add a vlv_disable_pll to prevent disabling it
when pipe B shuts down.
I'm guessing on the references here, I expect this to bite any config
where multiple displays are active or displays are moved from pipe to
pipe.
v2: re-add bits in vlv_update_pll to keep from confusing the state checker
v3: use enum pipe checks (Daniel)
set CRI clock source early (Ville)
consistently set CRI clock source everywhere (Ville)
v4: drop unnecessary setting of bit in vlv enable pll (Ville)

The values were taken from the HDMI spec, but they assumed
exact x/1.001 clocks. Since we round the clocks, we also need
to calculate different N and CTS values.
Note that the N for 25.2/1.001 MHz at 44.1 kHz audio is out of
spec. Hopefully this mode is rarely used and/or HDMI sinks
tolerate overly large values of N.

drm/i915: sanitize forcewake registers on reset
To make this work both for resets and for BIOS takeover just add the
forcewake clearing call back to intel_uncore_early_sanitize.
We need to clear the forcewake in early sanitize so that the forcewak
dance in intel_uncore_init (to figure out whether we have mt or legacy
forcewake on ivb) works. That cleanup fits in nicely with the general
topic of early_sanitize to prepare for the very first mmio ops.

commit b2ea8ef559b4d94190009f3651b5b3ab7c05afd3 upstream.
Apparently they need the same treatment as primary planes. This fixes
modesetting failures because of stuck cursors (!) on Thomas' i830M
machine.
I've figured while at it I'll also roll it out for the ivb 3 pipe
version of this function. I didn't do this for i845/i865 since Bspec
says the update mechanism works differently, and there's some
additional rules about what can be updated in which order.

commit 48f34e10169dbb3dd7a19af64e328492b7f54af4 upstream.
The ns2501 controller seems to need the dpll and dvo port to accept
the timing update commands. Quick testing on my x30 here seems to
indicate that other dvo controllers don't mind. So let's move the
->mode_set callback to a place where we have the port up and running
already.

commit da95c788ef0c645378ffccb7060a0df1a33aee38 upstream.
All error paths will want to keep the mm node, so handle this at the
function exit. This fixes an ioremap failure error path.
Also add some comments to make the function a bit easier to understand.
