Even though this is required for degamma since DCE HW only supports a
couple predefined LUTs we can just program the LUT directly for regamma.
This fixes dark screens which occurs when we program regamma to bypass
while degamma is using srgb LUT.

git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
Remove Exynos specific framebuffer structure and
relevant functions.
- it removes exynos_drm_fb structure which is a wrapper of
drm_framebuffer and unnecessary two exynos specific callback
functions, exynos_drm_destory() and exynos_drm_fb_create_handle()
because we can reuse existing drm common callback ones instead.

Now exynos_drm_fb is just an empty wrapper around drm_framebuffer, we
can drop it.

Since drm_framebuffer can now store GEM objects directly, place them
there rather than in our own subclass. As this makes the framebuffer
create_handle and destroy functions the same as the GEM framebuffer
helper, we can reuse those.

On Geminilake, sometimes audio card is not getting
detected after reboot. This is a spurious issue happening on
Geminilake. HW codec and HD audio controller link was going
out of sync for which there was a fix in i915 driver but
was not getting invoked for GLK. Extending this fix to GLK as well.
Tested by Du,Wenkai on GLK board.
Bspec: 21829
v2: Instead of checking GEN9_BC, BXT and GLK macros, use IS_GEN9 macro (Jani N)

We have to cleanup after i915_perf_init(), even on the error path, as it
passes a pointer into the module to the sysfs core. If we fail to
unregister the sysctl table, we leave a dangling pointer which then may
explode anytime later.

The VBT contains the DDC pin to use for specific ports. Alas, sometimes
the field appears to contain bogus data, and while we check for it later
on in intel_gmbus_get_adapter() we fail to check the returned NULL on
errors. Oops results.
The simplest approach seems to be to catch and ignore the bogus DDC pins
already at the VBT parsing phase, reverting to fixed per port default
pins. This doesn't guarantee display working, but at least it prevents
the oops. And we continue to be fuzzed by VBT.
One affected machine is Dell Latitude 5590 where a BIOS upgrade added
invalid DDC pins.

While thinking about sporadic failures of perf_pmu/rc6-runtime-pm* tests
on some CI machines I have concluded that: a) the PMU readout of RC6 can
race against runtime PM transitions, and b) there are other reasons than
being runtime suspended which can cause intel_runtime_pm_get_if_in_use to
fail.
Therefore when estimating RC6 the code needs to assert we are indeed in
suspended state, and if not, the best we can do is return the last known
RC6 value.
Without this check we can calculate the estimated value based on un-
initialized or inappropriate internal state, which can result in over-
estimation, or in any case incorrect value being returned.
v2:
* Re-arrange the code a bit to avoid second unlock and return branch.
(Chris Wilson)
v3:
* Insert some strategic blank lines and improve commit msg.

When cancelling the requests and clearing out the ports following a
successful preemption completion, also clear the active flag. I had
assumed that all preemptions would be followed by an immediate dequeue
(preserving the active user flag), but under rare circumstances we may
be triggering a preemption for the second port only for it to have
completed before the preemotion kicks in; leaving execlists->active set
even though the system is now idle.
We can clear the flag inside the common execlists_cancel_port_requests()
as the other users also expect the semantics of active being cleared.

initialization
Much error exist in host dmesg during guest boot up with loca display
enabled.
gvt: vgpu 1: invalid range gmadr 0x0 size 0x0
This error happens when qemu get dmabuf info in case that the virtual
display plane is enabled but its base address is an invalid 0, such
case may be true before guest enable its plane. At this moment, its
state is copied from host where the plane may be enabled.
This patch disable primary/sprite/cursor plane at virtual display
initialization, so intel_vgpu_decode_primary/cursor/sprite could
return early as plane is disabled, then plane base check is skipped and
error message disapper.

GVT-g dispatches request to host i915 and depends on i915 notify
ring interrupt mechanism to check completion of request.
For now MI_USER_INTERRUPT in guest requests is passed through
in GVT-g cmd parser and i915 does not use it, which causes
unnecessary interrupt handling in i915.
On the other hand, if several requests from guest are combined into
one request in and contain MI_USER_INTERRUPT in the middle of
combined request. GVT-g still has to wait on the whole request to
complete to inject user interrupts to guest.
This patch makes all the MI_USER_INTERRUPT nop to save some interrupt
handling.
Here is test result to run glmark2 on guest for 10 seconds:
host master interrupts number is reduced from 16021 to 11162
host user interrupts number is reduced from 7936 to 3536

LSPCON adapters in low-power state may ignore the first I2C write during
TMDS output buffer enabling, resulting in a blank screen even with an
otherwise enabled pipe. Fix this by reading back and validating the
written value a few times.
The problem was noticed on GLK machines with an onboard LSPCON adapter
after entering/exiting DC5 power state. Doing an I2C read of the adapter
ID as the first transaction - instead of the I2C write to enable the
TMDS buffers - returns the correct value. Based on this we assume that
the transaction itself is sent properly, it's only the adapter that is
not ready for some reason to accept this first write after waking from
low-power state. In my case the second I2C write attempt always
succeeded.

Hardware understands the regamma LUT as a piecewise linear function,
with points spaced exponentially along the range. We previously
programmed the LUT for range [2^-10, 2^0). This causes (normalized)
color values of 1 (=2^0) to miss the programmed LUT, and fall onto the
end region.
For DCE, the end region is extrapolated using a single (base, slope)
pair, using the max y-value from the last point in the curve as base.
This presents a problem, since this value affects all three color
channels. Scaling down the intensity of say - the blue regamma curve -
will not affect it's end region. This is especially noticiable when
using RedShift. It scales down the blue and green channels, but leaves
full-intensity colors unshifted.
Therefore, extend the range to cover [2^-10, 2^1) by programming another
hardware segment, containing only one point. That way, we won't be
hitting the end region.
Note that things are a bit different for DCN, since the end region can
be set per-channel.

Commit 8a7eda7686675b73d74c22c0d5b83059f9d783f6 ("drm: omapdrm: dispc:
Pass DISPC pointer to remaining dispc API functions") made dpi.c use
ctx->pll even when there's no PLL, causing a crash at modeset on AM4
EVM, and presumably all OMAP2/3 boards.
Fix this by having struct dpi_data pointer in the ctx instead, giving
access to dispc without going through the pll.

Two years ago I tried an AMD Radeon E8860 embedded GPU with the drm driver.
The dmesg output included driver warnings about an invalid PCIe lane width.
Tracking the problem back led to si_set_pcie_lane_width_in_smc().
The calculation of the lane widths via ATOM_PPLIB_PCIE_LINK_WIDTH_MASK and
ATOM_PPLIB_PCIE_LINK_WIDTH_SHIFT macros did not increment the resulting
value, per the comment in pptable.h ("lanes - 1"), and per usage elsewhere.
Applying the increment silenced the warnings.
The code has not changed since, so either my analysis was incorrect or the
bug has gone unnoticed. Hence submitting this as an RFC.
