commit 7a6c6243b44a439bda4bf099032be35ebcf53406 upstream.
The BXT/GLK DPLL can't generate certain frequencies. We already
reject the 233-240MHz range on both. But on GLK the DPLL max
frequency was bumped from 300MHz to 594MHz, so now we get to
also worry about the 446-480MHz range (double the original
problem range). Reject any frequency within the higher
problematic range as well.

commit d1f5a3fc85566e9ddce9361ef180f070367e6eab upstream.
In some cases we have the handle those explicitly as the fallback
connector type detection fails and marks those as eDP connectors.
Attempting to use such a connector with mutter leads to a crash of mutter
as it ends up with two eDP displays.
Information is taken from the official DCB documentation.

commit 688f97ed3f5e339c0c2c09d9ee7ff23d5807b0a7 upstream.
When run igt@kms_vrr in a device that uses DCN2.1 architecture, we
noticed multiple failures. Furthermore, when we tested a VRR demo, we
noticed a system hang where the mouse pointer still works, but the
entire system freezes; in this case, we don't see any dmesg warning or
failure messages kernel. This happens due to a lack of vupdate_no_lock
interrupt, making the userspace wait eternally to get the event back.
For fixing this issue, we need to add the vupdate_no_lock interrupt in
the interrupt list.

wait_flush is also called at the beginning to ensure previous

This fixes corrupted display output in HDMI deep color
10/12 bpc mode at least as observed on AMD Mullins, DCE-8.3.
It will hopefully also provide fixes for other DCE's up to
DCE-11, assuming those will need similar fixes, but i could
not test that for HDMI due to lack of suitable hw, so viewer
discretion is advised.
dce110_stream_encoder_hdmi_set_stream_attribute() is used for
HDMI setup on all DCE's and is missing color_depth assignment.
dce110_program_pix_clk() is used for pixel clock setup on HDMI
for DCE 6-11, and is missing color_depth assignment.
Additionally some of the underlying Atombios specific encoder
and pixelclock setup functions are missing code which is in
the classic amdgpu kms modesetting path and the in the radeon
kms driver for DCE6/DCE8.
encoder_control_digx_v3() - Was missing setup code wrt. amdgpu
and radeon kms classic drivers. Added here, but untested due to
lack of suitable test hw.
encoder_control_digx_v4() - Added missing setup code.
Successfully tested on AMD mullins / DCE-8.3 with HDMI deep color
output at 10 bpc and 12 bpc.
Note that encoder_control_digx_v5() has proper setup code in place
and is used, e.g., by DCE-11.2, but this code wasn't used for deep
color setup due to the missing cntl.color_depth setup in the calling
function for HDMI.
set_pixel_clock_v5() - Missing setup code wrt. classic amdgpu/radeon
kms. Added here, but untested due to lack of hw.
set_pixel_clock_v6() - Missing setup code added. Successfully tested
on AMD mullins DCE-8.3. This fixes corrupted display output at HDMI
deep color output with 10 bpc or 12 bpc.

In set_clamp(), the comments and definitions for the COLOR_DEPTH_101010
and COLOR_DEPTH_121212 cases directly contradict the code comment which
explains how this should work, whereas the COLOR_DEPTH_888 case
is consistent with the code comments. Comment says the bitmask should
be chosen to align to the top-most 10 or 12 MSB's on a 14 bit bus, but
the implementation contradicts that: 10 bit case sets a mask for 12 bpc
clamping, whereas 12 bit case sets a mask for 14 bpc clamping.
Note that during my limited testing on DCE-8.3 (HDMI deep color)
and DCE-11.2 (DP deep color), this didn't have any obvious ill
effects, neither did fixing it change anything obvious for the
better, so this fix may be inconsequential on DCE, and just
reduce the confusion of innocent bystanders when reading the code
and trying to investigate problems with 10 bpc+ output.

During commit 88bc4178568b ("drm: Use new

macros have been changed to avoid ambiguity but just because of this
ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning
_SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but
instead of swapping phase values, let's adopt an easier approach Maxime
suggested:
It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to
invert DCLK polarity and this makes things really easier than before. So
let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE
as bit 26 and activating according to bus_flags the same way it is done
for all the other signals polarity.

As it turns out, vendor HDMI PHY driver for H6 has a pretty big table
of predefined values for various pixel clocks. However, most of them are
not useful/tested because they come from reference driver code. Vendor
PHY driver is concerned with only few of those, namely 27 MHz, 74.25
MHz, 148.5 MHz, 297 MHz and 594 MHz. These are all frequencies for
standard CEA modes.
Fix sun50i_h6_cur_ctr and sun50i_h6_phy_config with the values only for
aforementioned frequencies.
Table sun50i_h6_mpll_cfg doesn't need to be changed because values are
actually frequency dependent and not so much SoC dependent. See i.MX6
documentation for explanation of those values for similar PHY.

Channel 1 has polarity bits for vsync and hsync signals but driver never
sets them. It turns out that with pre-HDMI2 controllers seemingly there
is no issue if polarity is not set. However, with HDMI2 controllers
(H6) there often comes to de-synchronization due to phase shift. This
causes flickering screen. It's safe to assume that similar issues might
happen also with pre-HDMI2 controllers.
Solve issue with setting vsync and hsync polarity. Note that display
stacks with tcon top have polarity bits actually in tcon0 polarity
register.

Commit 0a038c1c29a7 ("drm/vc4: Move LBM creation out of
vc4_plane_mode_set()") changed the LBM allocation logic from first
allocating the LBM memory for the plane to running mode_set,
adding a gap in the LBM, and then running the dlist allocation filling
that gap.
The gap was introduced by incrementing the dlist array index, but was
never checking whether or not we were over the array length, leading
eventually to memory corruptions if we ever crossed this limit.
vc4_dlist_write had that logic though, and was reallocating a larger
dlist array when reaching the end of the buffer. Let's share the logic
between both functions.

[Why]
Find out when we try to disable CRC calculation,
crc generation is still enabled. Main reason is
that dc_stream_configure_crc() will never get
called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE.
[How]
Add checking condition that when source is
AMDGPU_DM_PIPE_CRC_SOURCE_NONE, we should also call
dc_stream_configure_crc() to disable crc calculation.
Also, clean up crc window when disable crc calculation.

dereference the wa_ctx.vma if they are set. To protect the error path

While reviewing Christian's annotation patch I noticed that we have a
user-after-free for the WAIT_FOR_SUBMIT case: We drop the syncobj
reference before we've completed the waiting.
Of course usually there's nothing bad happening here since userspace
keeps the reference, but we can't rely on userspace to play nice here!

commit 00cb645fd7e29bdd20967cd20fa8f77bcdf422f9 upstream.
Commit 25b4620ee822 ("drm/i915/dsi: Skip delays for v3 VBTs in vid-mode")
added an intel_dsi_msleep() helper which skips sleeping if the
MIPI-sequences have a version of 3 or newer and the panel is in vid-mode;
and it moved a bunch of msleep-s over to this new helper.
This was based on my reading of the big comment around line 730 which
starts with "Panel enable/disable sequences from the VBT spec.",
where the "v3 video mode seq" column does not have any wait t# entries.
Given that this code has been used on a lot of different devices without
issues until now, it seems that my interpretation of the spec here is
mostly correct.
But now I have encountered one device, an Acer Aspire Switch 10 E
SW3-016, where the panel will not light up unless we do actually honor the
panel_on_delay after exexuting the MIPI_SEQ_PANEL_ON sequence.
What seems to set this model apart is that it is lacking a
MIPI_SEQ_DEASSERT_RESET sequence, which is where the power-on
delay usually happens.
Fix the panel not lighting up on this model by using an unconditional
msleep(panel_on_delay) instead of intel_dsi_msleep() when there is
no MIPI_SEQ_DEASSERT_RESET sequence.

[ Upstream commit bb83d5fb550bb7db75b29e6342417fda2bbb691c ]
The pch_get_backlight(), lpt_get_backlight(), and lpt_set_backlight()
functions operate directly on the hardware registers. If inverting the
value is needed, using intel_panel_compute_brightness(), it should only
be done in the interface between hardware registers and
panel->backlight.level.
The CPU mode takeover code added in commit 5b1ec9ac7ab5
("drm/i915/backlight: Fix backlight takeover on LPT, v3.") reads the
hardware register and converts to panel->backlight.level correctly,
however the value written back should remain in the hardware register
"domain".
This hasn't been an issue, because GM45 machines are the only known
users of i915.invert_brightness and the brightness invert quirk, and
without one of them no conversion is made. It's likely nobody's ever hit
the problem.

commit 0e53656ad8abc99e0a80c3de611e593ebbf55829 upstream.
When inserting a VMA, we restrict the placement to the low 4G unless the
caller opts into using the full range. This was done to allow usersapce
the opportunity to transition slowly from a 32b address space, and to
avoid breaking inherent 32b assumptions of some commands.
However, for insert we limited ourselves to 4G-4K, but on verification
we allowed the full 4G. This causes some attempts to bind a new buffer
to sporadically fail with -ENOSPC, but at other times be bound
successfully.
commit 48ea1e32c39d ("drm/i915/gen9: Set PIN_ZONE_4G end to 4GB - 1
page") suggests that there is a genuine problem with stateless addressing
that cannot utilize the last page in 4G and so we purposefully excluded
it. This means that the quick pin pass may cause us to utilize a buggy
placement.
