drm/i915: Use a hybrid scheme for fast register waits
Ville Syrjälä reported that in the majority of wait_for(I915_READ()) he
inspect, most completed within the first couple of reads and that the
delay between those wait_for() reads was the ratelimiting step for many
code paths. For example, __gen6_update_ring_freq() was blamed for
slowing down boot by many milliseconds, but under Ville's scrutiny the
issue was just excessive delay waiting for sandybridge_pcode_write().
We can eliminate the wait by initially using a busyspin upon the register
read and only fallback to the sleeping loop in cases where the hardware
is indeed too slow. A threshold of 2 microseconds is used as the initial
ballpark.
To avoid excessive code bloating from converting every wait_for() into a
hybrid busy/sleep loop, we extend wait_for_register_fw() and export it
for use by other callers.
Something appears to be off in the timing, but as far as I can tell it
is not along the event delivery path. The net effect appears to be
rendering flicker (the current render buffer appears on the scanout,
with what appears to be active rendering for a fraction of a frame) and
is causing me a headache.
The cursor is also being stalled by page flips, causing a "heavy mouse"
and jitter.
Daniel Stone did find what appears to the cause of the tearing, in
https://lists.freedesktop.org/archives/intel-gfx/2016-June/099466.html
That is the parameter passed to intel_atomic_commit_tail is the
old_state but we need the new_state to wait upon.
That leaves the question of how the CRC based tests didn't spot the
error (how can we improve our tests?), the issue of legacy cursor
stalling flips, and the issue of flips stalling the cursor. For the
moment, step back until the condundrum of new/old state is reviewed
along with more tests!

drm/i915: Remove request->reset_counter
Since commit 2ed53a94d8cb ("drm/i915: On GPU reset, set the HWS
breadcrumb to the last seqno") once a hang is completed, the seqno is
advanced past all current requests. With this we know that if we wake up
from waiting for a request, if a hang has occurred and reset completed,
our request will be considered complete (i.e.
i915_gem_request_completed() returns true). Therefore we only need to
worry about the situation where a hang has occurred, but not yet reset,
where we may need to release our struct_mutex. Since we don't need to
detect the completed reset using the global gpu_error->reset_counter
anymore, we do not need to track the reset_counter epoch inside the
request.

When a display update triggers a DDB re-allocation, we should start by
assuming that only the updated pipes need to be re-allocated (we have
logic later that may add additional pipes if, e.g., a modeset triggers a
change to the global allocation).
We were erroneously using the _active_ pipes as our starting point
rather than the changed pipes. This causes us to grab CRTC locks that
we didn't actually need, reducing parallelism. Given the recent
non-blocking atomic changes, it also causes legacy pageflips against one
CRTC to return -EBUSY if there's an outstanding pageflip against a
different CRTC (a situation easily triggered via compositors like
Weston).

drm/i915/guc: don't ever forward VBlank to the GuC
If a context waiting for VBlank were switched out, switching
in the next context and generating a CSB event in the process,
then the GuC would have to put the context back in the queue,
and then observe the subsequent VBlank interrupt so that it
could resubmit the suspended context.
However, we always set the CTX_CTRL_INHIBIT_SYN_CTX_SWITCH bit
in the RING_CONTEXT_CONTROL register, so this case cannot occur.
Furthermore we don't use the GuC's internal scheduler or allow
it to auto-resubmit workloads. Consequently, the GuC doesn't
need to see VBlanks, and by sending them to it we may be waking
it up unnecessarily, which might reduce RC6 residency and
increase power consumption.
So this patch removes the setting of the GFC_FORWARD_VBLANK
field from the code that diverts interrupts towards the GuC.
(The code to direct interrupts to the host, OTOH, continues to
explicitly set the field to "never send VBlanks to the GuC".)
v3:
Remove the line of code completely (original set the field
to ALWAYS forward, v1 changed it to CONDITIONAL forwarding,
v2 explicitly set it to NEVER, v3 just doesn't touch it at
all, as we know it's already set to NEVER).
Gen8 versions of these macros were updated a few months ago
(e8ebd8e drm/i915: eliminate 'temp' in gen8_for_each macros)
originally because at least one iterator could generate an
out of bounds access, but also because eliminating the 'temp'
parameter generated smaller and faster code.

but while we're changing these, we might as well make them as
much like the gen8 versions as possible, including the style
of using "&& (..., true)" rather than ": (..., 1) : 0", and
of course eliminating the redundant 'temp'.
Furthermore, the "all_pdes" version is only used in one place,
so we can improve code efficiency by changing both the macro
parameters and the calling code to reduce extra dereferences.

drm/i915: Only switch to default context when evicting from GGTT
The contexts only pin space within the global GTT. Therefore forcing the
switch to the perma-pinned kernel context only has an effect when trying
to evict from and find room within the global GTT. We can then restrict
the switch to only when operating on the default context. This is mostly
a no-op as full-ppgtt only exists with execlists at present which skips
the context switch anyway.

drm/i915: Split idling from forcing context switch
We only need to force a switch to the kernel context placeholder during
eviction. All other uses of i915_gpu_idle() just want to wait until
existing work on the GPU is idle. Rename i915_gpu_idle() to
i915_gem_wait_for_idle() to avoid any implications about "parking" the
context first.

drm/i915: No need to wait for idle on L3 remap
As the L3 remapping is applied before the next execution, there is no
need to wait until all previous uses are idle, the application will not
occur any sooner.

drm/i915: Mark all default contexts as uninitialised after context loss
When the GPU is reset or state lost through suspend, every default
legacy context needs to reload their state - both the golden render
state and the L3 mapping. Only context images explicitly saved to memory
(i.e. all execlists and non-default legacy contexts) will retain their
state across the reset.
Chris Wilson [Fri, 24 Jun 2016 13:55:54 +0000 (14:55 +0100)]
drm/i915: Treat kernel context as initialised
The kernel context exists simply as a placeholder and should never be
executed with a render context. It does not need the golden render
state, as that will always be applied to a user context. By skipping the
initialisation we can avoid issues in attempting to program the golden
render context when trying to make the hardware idle.

drm/i915: Move legacy kernel context pinning to intel_ringbuffer.c
This is so that we have symmetry with intel_lrc.c and avoid a source of
if (i915.enable_execlists) layering violation within i915_gem_context.c -
that is we move the specific handling of the dev_priv->kernel_context
for legacy submission into the legacy submission code.
This depends upon the init/fini ordering between contexts and engines
already defined by intel_lrc.c, and also exporting the context alignment
required for pinning the legacy context.
v2: Separate out pin/unpin context funcs for greater symmetry with
intel_lrc. One more step towards unifying behaviour between the two
classes of engines and towards fixing another bug in i915_switch_context
vs requests.

drm/i915: Skip idling an idle engine
During suspend (or module unload), if we have never accessed the engine
(i.e. userspace never submitted a batch to it), the engine is idle. Then
we attempt to idle the engine by forcing it to the default context,
which actually means we submit a render batch to setup the golden
context state and then wait for it to complete. We can skip this
entirely as we know the engine is idle.

drm/i915: Move module init/exit to i915_pci.c
The module init/exit routines are a wrapper around the PCI device
init/exit, so move them across.
Note that in order to avoid exporting the driver struct, instead of
manipulating driver.features inside i915_init we instead opt to simply
exit if i915.modeset is disabled.

drm/i915: Remove user controllable DRM_ERROR for i915_getparam()
The GETPARAM ioctl writes to a user supplied address. If that address is
invalid, it is the user's error and not the driver's, so quietly report
EFAULT and don't blame ourselves with a DRM_ERROR.

drm/i915: Merge i915_dma.c into i915_drv.c
i915_dma.c used to contain the DRI1/UMS horror show, but now all that
remains are the out-of-place driver level interfaces (such as
allocating, initialising and registering the driver). These should be in
i915_drv.c alongside similar routines for suspend/resume.
drm_connector_register_all() is now automatically called by
drm_dev_register(), and so we no longer have to do so ourselves (via
intel_modeset_register() after calling drm_dev_register()). Similarly
for unregistering.
Chris Wilson [Fri, 24 Jun 2016 13:00:19 +0000 (14:00 +0100)]
drm/i915: Demidlayer driver unloading
To complete the transition to manual control of load/unload, we need to
take over unloading from i915_pci_remove(). This allows us to correctly
order our unregister vs shutdown phases, which currently are inverted
due to the midlayer.
However, the unload sequence is still invalid as we shutdown the driver
with the last reference. Ideally, all we want to do is remove the
userspace access on device removal, deferring the cleanup to the
drm_dev_release() - breaking the reference cycles is then left as an
exercise for the reader.
Chris Wilson [Fri, 24 Jun 2016 13:00:18 +0000 (14:00 +0100)]
drm/i915: Demidlayer driver loading
Take control over allocating, loading and registering the driver from the
DRM midlayer by performing it manually from i915_pci_probe. This allows
us to carefully control the order of when we setup the hardware vs when
it becomes visible to third parties (including userspace). The current
ordering makes the driver visible to userspace first (in order to
coordinate with removed DRI1 userspace), but that ordering incurs risk.
The risk increases as we strive for more asynchronous loading.
One side effect of controlling the allocation is that we can allocate
both the drm_device + drm_i915_private in one block, the next step
towards subclassing.
Unload is still left as before, a mix of midlayer and driver.
v2: After drm_dev_init(), we should call drm_dev_unref() so that we call
drm_dev_release() and free everything from drm_dev_init().
v3: Fixup missed error code for failing to allocate dev_priv

drm/i915: Register debugfs interface last
Currently debugfs files are created before the driver is even loads.
This gives the opportunity for userspace to open that interface and poke
around before the backing data structures are initialised - with the
possibility of oopsing or worse.
Move the creation of the debugfs files to our registration phase, where
we announce our presence to the world when we are ready, i.e the
sequence changes from

drm/i915: Move connector registration to driver registration
Defer connector registration from during construction to the driver

e.g. not using debugfs before it is ready.

drm/i915: Move backlight registration to connector registration
Currently the backlight is being registered in the load phase (before
the display and its objects are registered). Move the backlight
registration into the analogous phase by performing it from the
connector registration, just after its creation.
Chris Wilson [Fri, 24 Jun 2016 13:00:14 +0000 (14:00 +0100)]
drm/i915: Move registration actions to connector->late_register
With the introduction of a connector->func for callback from
drm_connector_register() we can move all the tasks that we want to do
upon registration into that callback. Later, this will allow us to
reorder the registration and defer it until after the device is setup
and ready for userspace.

drm/i915: Move panel's backlight setup next to panel init
Currently setting up the backlight for a panel is sometimes done
together with initialising the panel, and sometimes after the connector
is registered. The backlight setup does not depend upon connector
registration (i.e. access to sysfs/debugfs and the kobject hierachy) so
perform it consistently just after panel initialisation.
Note the discrepancy here as destroying the panel is done during
connector unregistration...

drm/i915: Small compaction of the engine init code
Effectively removes one layer of indirection between the mask of
possible engines and the engine constructors. Instead of spelling
out in code the mapping of HAS_<engine> to constructors, makes
more use of the recently added data driven approach by putting
engine constructor vfuncs into the table as well.
Effect is fewer lines of source and smaller binary.
At the same time simplify the error handling since engine
destructors can run on unitialized engines anyway.
Similar approach could be done for legacy submission is wanted.
v2: Removed ugly BUILD_BUG_ONs in favour of newly introduced
ENGINE_MASK and HAS_ENGINE macros.
Also removed the forward declarations by shuffling functions
around.
v3: Warn when logical_rings table does not contain enough data
and disable the engines which could not be initialized.

v4: Chris Wilson suggested a nicer engine init loop.
