      drm/nouveau/disp/nv50-: fix center/aspect-corrected scaling · 91ae8724
      由 Ilia Mirkin 提交于 
      [ Upstream commit 533f4752407543f488a9118d817b8c504352b6fb ]

Previously center scaling would get scaling applied to it (when it was
only supposed to center the image), and aspect-corrected scaling did not
always correctly pick whether to reduce width or height for a particular
combination of inputs/outputs.

      drm: Flush output polling on shutdown · ff0fbfac
      由 Chris Wilson 提交于 
      [ Upstream commit 3b295cb1a411d9c82bbfaa66bc17a8508716ed07 ]

We need to mark the output polling as disabled to prevent concurrent
irqs from queuing new work as shutdown the probe -- causing that work to
execute after we have freed the structs:

      Revert "drm/amd/powerplay: Enable/Disable NBPSTATE on On/OFF of UVD" · a935d78e
      由 Shirish S 提交于 
      [ Upstream commit 00fedbe629bfc0a51c07b6e665265ce31d8b6f3c ]

This reverts commit dbd8299c32f6f413f6cfe322fe0308f3cfc577e8.

Reason for revert:
This patch sends  msg PPSMC_MSG_DisableLowMemoryPstate(0x002e)
in wrong of sequence to SMU which is before PPSMC_MSG_UVDPowerON (0x0008).
This leads to SMU failing to service the request as it is
dependent on UVD to be powered ON, since it accesses UVD
registers.

This msg should ideally be sent only when the UVD is about to decode
a 4k video.

      drm/amd/display: readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines · 70ec2eec
      由 Nick Desaulniers 提交于 
      [ Upstream commit 0f0727d971f6fdf8f1077180d495ddb9928f0c8b ]

arch/x86/Makefile disables SSE and SSE2 for the whole kernel.  The
AMDGPU drivers modified in this patch re-enable SSE but not SSE2.  Turn
on SSE2 to support emitting double precision floating point instructions
rather than calls to non-existent (usually available from gcc_s or
compiler_rt) floating point helper routines for Clang.

This was originally landed in:
commit 10117450735c ("drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines")
but reverted in:
commit 193392ed9f69 ("Revert "drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines"")
due to bugreports from GCC builds. Add guards to only do so for Clang.

      由 Lyude Paul 提交于 
      [ Upstream commit 34ca26a98ad67edd6e4870fe2d4aa047d41a51dd ]

It appears when testing my previous fix for some of the legacy
modesetting issues with MST, I misattributed some kernel splats that
started appearing on my machine after a rebase as being from upstream.
But it appears they actually came from my patch series:

[    2.980884] ---[ end trace 5eb47a76277d4731 ]---

The cause of this appears to be due to the fact that if there's
pre-existing display state that was set by the BIOS when i915 loads, it
will attempt to perform a modeset before the driver is registered with
userspace. Since this happens before the driver's registered with
userspace, it's connectors are also unregistered and thus-states which
would turn on DPMS on a connector end up getting rejected since the
connector isn't registered.

These bugs managed to get past Intel's CI partially due to the fact it
never ran a full test on my patches for some reason, but also because
all of the tests unload the GPU once before running. Since this bug is
only really triggered when the drivers tries to perform a modeset before
it's been fully registered with userspace when coming from whatever
display configuration the firmware left us with, it likely would never
have been picked up by CI in the first place.

After some discussion with vsyrjala, we decided the best course of
action would be to just move the unregistered connector checks out of
update_connector_routing() and into drm_atomic_set_crtc_for_connector().
The reason for this being that legacy modesetting isn't going to be
expecting failures anywhere (at least this is the case with X), so
ideally we want to ensure that any DPMS changes will still work even on
unregistered connectors. Instead, we now only reject new modesets which
would change the current CRTC assigned to an unregistered connector
unless no new CRTC is being assigned to replace the connector's previous
one.

      drm/i915: Make sure cdclk is high enough for DP audio on VLV/CHV · 057cdb6f
      由 Ville Syrjälä 提交于 
      [ Upstream commit a8f196a0fa6391a436f63f360a1fb57031fdf26c ]

On VLV/CHV there is some kind of linkage between the cdclk frequency
and the DP link frequency. The spec says:
"For DP audio configuration, cdclk frequency shall be set to
 meet the following requirements:
 DP Link Frequency(MHz) | Cdclk frequency(MHz)
 270                    | 320 or higher
 162                    | 200 or higher"

I suspect that would more accurately be expressed as
"cdclk >= DP link clock", and in any case we can express it like
that in the code because of the limited set of cdclk (200, 266,
320, 400 MHz) and link frequencies (162 and 270 MHz) we support.

Without this we can end up in a situation where the cdclk
is too low and enabling DP audio will kill the pipe. Happens
eg. with 2560x1440 modes where the 266MHz cdclk is sufficient
to pump the pixels (241.5 MHz dotclock) but is too low for
the DP audio due to the link frequency being 270 MHz.

v2: Spell out the cdclk and link frequencies we actually support

This patch adds support for the Armadeus ST0700 Adapt. It comes with a
Santek ST0700I5Y-RBSLW 7.0" WVGA (800x480) TFT and an adapter board so
that it can be connected on the TFT header of Armadeus Dev boards.

      [ Upstream commit 517b91f4cde3043d77b2178548473e8545ef07cb ]

[What]
readptr read always returns zero, since most likely
these blocks are either power or clock gated.

[How]
fetch rptr after amdgpu_ring_alloc() which informs
the power management code that the block is about to be
used and hence the gating is turned off.

      drm/amdgpu: fix ring test failure issue during s3 in vce 3.0 (V2) · 7abeffff
      由 Louis Li 提交于 
      [ Upstream commit ce0e22f5d886d1b56c7ab4347c45b9ac5fcc058d ]

[What]
vce ring test fails consistently during resume in s3 cycle, due to
mismatch read & write pointers.
On debug/analysis its found that rptr to be compared is not being
correctly updated/read, which leads to this failure.
Below is the failure signature:
	[drm:amdgpu_vce_ring_test_ring] *ERROR* amdgpu: ring 12 test failed
	[drm:amdgpu_device_ip_resume_phase2] *ERROR* resume of IP block <vce_v3_0> failed -110
	[drm:amdgpu_device_resume] *ERROR* amdgpu_device_ip_resume failed (-110).

[How]
fetch rptr appropriately, meaning move its read location further down
in the code flow.
With this patch applied the s3 failure is no more seen for >5k s3 cycles,
which otherwise is pretty consistent.

We assumed that vm_mmap() would reject an attempt to mmap past the end of
the filp (our object), but we were wrong.

Applications that tried to use the mmap beyond the end of the object
would be greeted by a SIGBUS. After this patch, those applications will
be told about the error on creating the mmap, rather than at a random
moment on later access.

This is much louder then we want. VCPI allocation failures are quite
normal, since they will happen if any part of the modesetting process is
interrupted by removing the DP MST topology in question. So just print a

      drm/vblank: Allow dynamic per-crtc max_vblank_count · 2b4f5679
      由 Ville Syrjälä 提交于 
      [ Upstream commit ed20151a7699bb2c77eba3610199789a126940c4 ]

On i965gm we need to adjust max_vblank_count dynamically
depending on whether the TV encoder is used or not. To
that end add a per-crtc max_vblank_count that takes
precedence over its device wide counterpart. The driver
can now call drm_crtc_set_max_vblank_count() to configure
the per-crtc value before calling drm_vblank_on().

Also looks like there was some discussion about exynos needing
similar treatment.

v2: Drop the extra max_vblank_count!=0 check for the
    WARN(last!=current), will take care of it in i915 code (Daniel)
    WARN_ON(!inmodeset) (Daniel)
    WARN_ON(dev->max_vblank_count)
    Pimp up the docs (Daniel)
