cc3f90f063 drm/i915/glk: Reuse broxton code for geminilake
Geminilake is mostly backwards compatible with broxton, so change most
of the IS_BROXTON() checks to IS_GEN9_LP(). Differences between the
platforms will be implemented in follow-up patches.

v2: Don't reuse broxton's path in intel_update_max_cdclk().
    Don't set plane count as in broxton.

v3: Rebase

v4: Include the check intel_bios_is_port_hpd_inverted().
    Commit message.

v5: Leave i915_dmc_info() out; glk's csr version != bxt's. (Rodrigo)

v6: Rebase.

v7: Convert a few mode IS_BROXTON() occurances in pps, ddi, dsi and pll
    code. (Rodrigo)

v8: Squash a couple of DDI patches with more conversions. (Rodrigo)

8bf41b7298 drm/i915/gen6+: Clear upper data byte during PCODE write
The spec calls for the upper data byte to be cleared before most of the
PCODE write commands, for others like IPS control it doesn't say
anything about this byte. Let's clear it in case it's clobbered somehow,
especially that there are places where we only do a PCODE write without
a preceding PCODE read.

31613268c0 drm/i915/audio: extend get_saved_enc() to support more scenarios
In initialization, audio driver will call functions get_eld() and etc.
But at that time, audio driver may not know whether it is DP MST or not.
In the original function get_saved_enc(), if it is DP MST, it requires to
set the pipe to the correct value, otherwise, pipe to be -1.

Although audio driver can get the knowledge whether it is in DP MST mode
or not by reading the codec register. It will drop performance each time
before it calls the get_eld and other similar functions. As gfx driver can
easily know whether it is in DP MST mode or not. Let's extend the
get_saved_enc() function to handle the situation that audio driver
still sends the device id info even it is in DP SST mode and return
the correct intel_encoder instead of panic.

908764f6d0 drm/i915/lspcon: Enable AUX interrupts for resume time initialization
For LSPCON initialization during system resume we need AUX
functionality, but we call the corresponding encoder reset hook with all
interrupts disabled. Without interrupts we'll do a poll-wait for AUX
transfer completions, which adds a significant delay if the transfers
timeout/need to be retried for some reason.

Fix this by enabling interrupts before calling the reset hooks. Note
that while this will enable AUX interrupts it will keep HPD interrupts
disabled, in a similar way to the init time output setup code.

This issue existed since LSPCON support was added.

v2:
- Rebased on drm-tip.

f559013436 Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
On the userspace side, all the basics are working, and most of glmark2
is working.  I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%).  I expect
to push the mesa patches today or tomorrow.

There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree.  If that can land in the next day or two, there might
be a second late pull request for drm/msm.

In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step.  All those patches should also help
out atomic weston (when those patches eventually land).

dc55ac3b52 drm/bridge: Add ti-tfp410 DVI transmitter driver
Add very basic ti-tfp410 DVI transmitter driver. The only feature
separating this from a completely dummy bridge is the EDID read
support trough DDC I2C. Even that functionality should be in a
separate generic connector driver. However, because of missing DRM
infrastructure support the connector is implemented within the bridge
driver. Some tfp410 HW specific features may be added later if needed,
because there is a set of registers behind i2c if it is connected.

This implementation is tested against my new tilcdc bridge support
and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document
is also updated.

Recover from sync lost error flood by resetting the LCDC instead of
turning off the SYNC_LOST error IRQ. When LCDC starves on limited
memory bandwidth it may sometimes result an error situation when the
picture may have shifted couple of pixels to right and SYNC_LOST
interrupt is generated on every frame. LCDC main reset recovers from
this situation and causes a brief blanking on the screen.

The commit d8ff0c63fbcb ("drm/tilcdc: Adjust the FB_CEILING address")
added an adjustment of the FB_CEILING address. This is done by decrementing
the address by one.

On the AM335x (rev 0x4F201000) the framebuffer is rotated left over the
display border, because the ceiling address is 8f276fff instead of
8f277000. Since this adjustment isn't necessary for the LCDC v2, the
origin ceiling address should be used.

cb42e20ea0 drm/tilcdc: add a workaround for failed clk_set_rate()
Some architectures don't use the common clock framework and don't
implement all the clk interfaces for every clock. This is the case
for da850-lcdk where clk_set_rate() only works for PLL0 and PLL1.

Trying to set the clock rate for the LCDC clock results in -EINVAL
being returned.

As a workaround for that: if the call to clk_set_rate() fails, fall
back to adjusting the clock divider instead. Proper divider value is
calculated by dividing the current clock rate by the required pixel
clock rate in HZ.

This code is based on a hack initially developed internally for
baylibre by Karl Beldan <kbeldan@baylibre.com>.

Tested with a da850-lcdk with an LCD display connected over VGA.

Looks like we're only initializing dev_priv->atomic_cdclk_freq
at resume and commit times, not at init time. Let's do that as
well.

We're now hitting the 'WARN_ON(intel_state->cdclk == 0)' in
hsw_compute_linetime_wm() on account of populating
intel_state->cdclk from dev_priv->atomic_cdclk_freq.
Previously we were mispopulating intel_state->cdclk with
dev_priv->cdclk_freq which always had a proper value at init
time and hence the WARN_ON() didn't trigger.

Something I missed before sending off the partial series was that the
non-scheduler guc reset path was broken (in the full series, this is
pushed to the execlists reset handler). The issue is that after a reset,
we have to refill the GuC workqueues, which we do by resubmitting the
requests. However, if we already have submitted them, the fences within
them have already been used and triggering them again is an error.
Instead, just repopulate the guc workqueue.

4d357af499 drm/i915/guc: Keep the execbuf client allocated across reset
In order to avoid some complexity in trying to reconstruct the
workqueues across reset, remember them instead. The issue comes when we
have to handle a reset between request allocation and submission, the
request has reserved space in the wq, but is not in any list so we fail
to restore the reserved space. By keeping the execbuf client intact
across the reset, we also keep the reservations.

334636c67e drm/i915: Trim i915_guc_info() stack usage
i915_guc_info() (part of debugfs output) tries to avoid holding
struct_mutex for a long period by copying onto the stack. This causes a
warning that the stack frame is massive, so stop doing that. We can even
forgo holding the struct_mutex here as that doesn't serialise the values
being read (and the lists used exist for the device lifetime).

potential NULL dereference).

Enable audio codec when DP MST is enabled if has_audio flag is set.
Disable audio codec when DP MST is disabled if has_audio flag is set.

Another separated patches to support DP MST audio will be implemented
in audio driver.

This patch is ported from
commit 3708d5e082 ("drm/i915: start adding dp mst audio")

And because commit 3708d5e082 ("drm/i915: start adding dp mst audio")
breaks MST multi-monitor setups on some platforms, the orignal patch is
reverted by
commit be754b101f ("Revert "drm/i915: start adding dp mst audio"")

As the multi-monitor setups issue is fixed, let's port the patch and
enable the dp mst audio.

a18dbba8f0 drm/i915: Move the release of PT page to the upper caller
a PT page will be released if it doesn't contain any meaningful mappings
during PPGTT page table shrinking. The PT entry in the upper level will
be set to a scratch entry.

Normally this works nicely, but in virtualization world, the PPGTT page
table is tracked by hypervisor. Releasing the PT page before modifying
the upper level PT entry would cause extra efforts.

As the tracked page has been returned to OS before losing track from
hypervisor, it could be written in any pattern. Hypervisor has to recognize
if a page is still being used as a PT page by validating these writing
patterns. It's complicated. Better let the guest modify the PT entry in
upper level PT first, then release the PT page.

David found another issue with priority bumping from mmioflips, where we
are accessing the requests concurrently to them being retired and freed.
Whilst we are skipping the dependency if has been submitted, that is not
sufficient to stop the dependency from disappearing if another thread
retires that request. To prevent we can either employ the struct_mutex (or a
request mutex in the future) to serialise retiring before it is freed.
Alternatively, we need to keep the dependencies alive using RCU whilst
they are being accessed via the DFS.

2401a00846 drm/msm: gpu: Add support for the GPMU
Most 5XX targets have GPMU (Graphics Power Management Unit) that
handles a lot of the heavy lifting for power management including
thermal and limits management and dynamic power collapse. While
the GPMU itself is optional, it is usually nessesary to hit
aggressive power targets.

The GPMU firmware needs to be loaded into the GPMU at init time via a
shared hardware block of registers. Using the GPU to write the microcode
is more efficient than using the CPU so at first load create an indirect
buffer that can be executed during subsequent initalization sequences.

After loading the GPMU gets initalized through a shared register
interface and then we mostly get out of its way and let it do
its thing.

fb03998192 drm/msm: Add adreno_gpu_write64()
Add a new generic function to write a "64" bit value. This isn't
actually a 64 bit operation, it just writes the upper and lower
32 bit of a 64 bit value to a specified LO and HI register.  If
a particular target doesn't support one of the registers it can
mark that register as SKIP and writes/reads from that register
will be quietly dropped.

This can be immediately put in place for the ringbuffer base and
the RPTR address.  Both writes are converted to use
adreno_gpu_write64() with their respective high and low registers
and the high register appropriately marked as SKIP for both 32 bit
targets (a3xx and a4xx). When a5xx comes it will define valid target
registers for the 'hi' option and everything else will just work.

49ec5b2e5a drm/msm/mdp5: handle SMP block allocations "atomically"
Previously, SMP block allocation was not checked in the plane's
atomic_check() fxn, so we could fail allocation SMP block allocation at
atomic_update() time.  Re-work the block allocation to request blocks
during atomic_check(), but not update the hw until committing the atomic
update.

Since SMP blocks allocated at atomic_check() time, we need to manage the
SMP state as part of mdp5_state (global atomic state).  This actually
ends up significantly simplifying the SMP management, as the SMP module
does not need to manage the intermediate state between assigning new
blocks before setting flush bits and releasing old blocks after vblank.
(The SMP registers and SMP allocation is not double-buffered, so newly
allocated blocks need to be updated in kms->prepare_commit() released
blocks in kms->complete_commit().)

4a0f012da3 drm/msm/mdp5: dynamically assign hw pipes to planes
(re)assign the hw pipes to planes based on required caps, and to handle
situations where we could not modify an in-use plane (ie. SMP block
reallocation).

This means all planes advertise the superset of formats and properties.
Userspace must (as always) use atomic TEST_ONLY step for atomic updates,
as not all planes may be available for use on every frame.

The mapping of hwpipe to plane is stored in mdp5_state, so that state
updates are atomically committed in the same way that plane/etc state
updates are managed.  This is needed because the mdp5_plane_state keeps
a pointer to the hwpipe, and we don't want global state to become out
of sync with the plane state if an atomic update fails, we hit deadlock/
backoff scenario, etc.  The use of state_lock keeps multiple parallel
updates which both re-assign hwpipes properly serialized.

1455adbd45 drm/msm/mdp5: handle non-fullscreen base plane case
If the bottom-most layer is not fullscreen, we need to use the BASE
mixer stage for solid fill (ie. MDP5_CTL_BLEND_OP_FLAG_BORDER_OUT).  The
blend_setup() code pretty much handled this already, we just had to
figure this out in _atomic_check() and assign the stages appropriately.

Also fix the case where there are zero enabled planes, where we also
need to enable BORDER_OUT.

host2guc_action() and host2guc_action_response() become guc_send()

Other host2guc_*() functions become simply guc_*().

Other entities are renamed basing on context they appear in:
 - HOST2GUC_ACTIONS_&           become INTEL_GUC_ACTION_*
 - HOST2GUC_{INTERRUPT,TRIGGER} become GUC_SEND_{INTERRUPT,TRIGGER}

747e5a5ff2 drm: hdlcd: Fix cleanup order
If hdlcd_drm_bind() fails at drm_fbdev_cma_init(), its cleanup will call
drm_mode_config_cleanup() as if to balance drm_mode_config_reset(). The
net result is that drm_connector_cleanup() will clean up the active
connectors long before component_unbind_all() gets called, so when the
connector later tries to clean up itself after being unbound, Bad Things
can happen:

a3f79ca63b drm/i915: Don't sanitize has_decoupled_mmio if platform is not broxton
The check in __intel_uncore_early_sanitize() to disable decoupled mmio
would disable it for every platform that is not broxton. While that's
not a problem now since only broxton supports that, simply setting
.has_decoupled_mmio in a new platform's device info wouldn't suffice. So
avoid future confusion and change the workaround to only change the
value of has_decoupled_mmio for broxton.

v2: git add compile fix. (Ander)

60abfbb86a drm/i915/audio: fix hdmi audio noise issue
Some monitors will have noise or even no sound after
applying the patch 6014ac12.

In patch 6014ac12, it will reset the cts value to 0 for HDMI.
However, we need to disable Enable CTS or M Prog bit. This is
the initial setting after HW reset.

41736a8e33 drm/i915: Use the precomputed value for whether to enable command parsing
As i915.enable_cmd_parser is an unsafe option, make it read-only at
runtime. Now that it is constant, we can use the value determined during
initialisation as to whether we need the cmdparser at execbuffer time.

v2: Remove the inline for its single user, it is clear enough (and
shorter) without!

9607ae7971 drm/i915/debugfs: Increment return value of gt.next_seqno
The i915_next_seqno read value is to be the next seqno used by the
kernel. However, in the conversion to atomics ops for gt.next_seqno, in
commit 28176ef4cf ("drm/i915: Reserve space in the global seqno during
request allocation"), this was changed from a post-increment to a
pre-increment. This increment was missed from the value reported by
debugfs, so in effect it was reporting the current seqno (last
assigned), not the next seqno.

e3f51ece02 drm/i915: cleanup use of INSTR_CLIENT_MASK
Doing cmd_header >> 29 to extract our 3-bit client value where we know
cmd_header is a u32 shouldn't then also require the use of a mask. So
remove the redundant operation and get rid of INSTR_CLIENT_MASK now that
there are no longer any users.

30576a2c46 drm/i915/debugfs: Drop i915_hws_info
i915_hws_info() has not been kept upto date (missing new engines) and so
I consider it to be unused. HWS is included in the error state, which
would be an avenue to retrieving it if required in future (possibly via
i915_engine_info). As it is currently oopsing with an rpm testcase, just
remove it.
