read_current_link_settings_on_detect() on eDP 1.4+ may use the
edp_supported_link_rates table which is set up by
detect_edp_sink_caps(), so that function needs to be called first.

For high-res (8K) or HFR (4K120) displays, using uncompressed pixel
formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the
"interesting" modes would be disabled, leaving only low-res or low
framerate modes.
This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS
clock is exceeded. Verified that 8K30 and 4K120 are now available and
working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700.

Calling kzalloc() and related functions requires the

kzalloc(sizeof(struct dcn10_ipp), GFP_KERNEL);
A lot of other headers also miss a direct include in this file,
but this is the only one that causes a problem for now.

A final attempt at enabling sse2 for GCC users.
Orininally attempted in:
commit 10117450735c ("drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines")
Reverted due to "reported instability" in:
commit 193392ed9f69 ("Revert "drm/amd/display: add -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines"")
Re-added just for Clang in:
commit 0f0727d971f6 ("drm/amd/display: readd -msse2 to prevent Clang from emitting libcalls to undefined SW FP routines")
The original report didn't have enough information to know if the GPF
was due to misalignment, but I suspect that it was. (The missing
information was the disassembly of the function at the bottom of the
trace, to see if the instruction pointer pointed to an instruction with
16B alignment memory operand requirements. The stack trace does show
the stack was only 8B but not 16B aligned though, which makes this a
strong possibility).
Now that the stack misalignment issue has been fixed for users of GCC
7.1+, reattempt adding -msse2. This matches Clang.
It will likely never be safe to enable this for pre-GCC 7.1 AND use a
16B aligned stack in these translation units.
This is only a functional change for GCC 7.1+ users, and should be boot
tested.

GCC earlier than 7.1 errors when compiling code that makes use of
`double`s and sets a stack alignment outside of the range of [2^4-2^12]:
$ cat foo.c
double foo(double x, double y) {
return x + y;
}
$ gcc-4.9 -mpreferred-stack-boundary=3 foo.c
error: -mpreferred-stack-boundary=3 is not between 4 and 12
This is likely why the AMDGPU driver was ever compiled with a different
stack alignment (and thus different ABI) than the rest of the x86
kernel. The kernel uses 8B stack alignment, while the driver was using
16B stack alignment in a few places.
Since GCC 7.1+ doesn't error, fix the ABI mismatch for users of newer
versions of GCC.
There was discussion about whether to mark the driver broken or not for
users of GCC earlier than 7.1, but since the driver currently is
working, don't explicitly break the driver for them here.
Relying on differing stack alignment is unspecified behavior, and
brittle, and may break in the future.
This patch is no functional change for GCC users earlier than 7.1. It's
been compile tested on GCC 4.9 and 8.3 to check the correct flags. It
should be boot tested when built with GCC 7.1+.
-mincoming-stack-boundary= or -mstackrealign may help keep this code
building for pre-GCC 7.1 users.
The version check for GCC is broken into two conditionals, both because
cc-ifversion is currently GCC specific, and it simplifies a subsequent
patch.

The x86 kernel is compiled with an 8B stack alignment via
`-mpreferred-stack-boundary=3` for GCC since 3.6-rc1 via
commit d9b0cde91c60 ("x86-64, gcc: Use -mpreferred-stack-boundary=3 if supported")
or `-mstack-alignment=8` for Clang. Parts of the AMDGPU driver are
compiled with 16B stack alignment.
Generally, the stack alignment is part of the ABI. Linking together two
different translation units with differing stack alignment is dangerous,
particularly when the translation unit with the smaller stack alignment
makes calls into the translation unit with the larger stack alignment.
While 8B aligned stacks are sometimes also 16B aligned, they are not
always.
Multiple users have reported General Protection Faults (GPF) when using
the AMDGPU driver compiled with Clang. Clang is placing objects in stack
slots assuming the stack is 16B aligned, and selecting instructions that
require 16B aligned memory operands.
At runtime, syscall handlers with 8B aligned stack call into code that
assumes 16B stack alignment. When the stack is a multiple of 8B but not
16B, these instructions result in a GPF.
Remove the code that added compatibility between the differing compiler
flags, as it will result in runtime GPFs when built with Clang. Cleanups
for GCC will be sent in later patches in the series.

A display that supports DRR can never really be considered
"synchronized" with any other display because we can dynamically
enable DRR (i.e. without modeset). this will cause their
relative CRTC positions to drift and lose sync. this will disrupt
features such as MCLK switching that assume and depend on
their permanent alignment (that can only change with modeset)

Clang warns:
../drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:2520:42:
error: implicit conversion from enumeration type 'enum transmitter' to
different enumeration type 'enum physical_phy_id'
[-Werror,-Wenum-conversion]
psr_context->smuPhyId = link->link_enc->transmitter;
~ ~~~~~~~~~~~~~~~~^~~~~~~~~~~
1 error generated.
As the comment above this assignment states, this is intentional. To
match previous warnings of this nature, add a conversion function that
explicitly converts between the enums and warns when there is a
mismatch.
See commit 828cfa29093f ("drm/amdgpu: Fix amdgpu ras to ta enums
conversion") and commit d9ec5cfd5a2e ("drm/amd/display: Use switch table
for dc_to_smu_clock_type") for previous examples of this.
v2: use PHYLD_UNKNOWN for the default case.

kfree has taken null pointer into account. hence it is safe to remove

UAPI Changes:
Cross-subsystem Changes:
Core Changes:
* Handle UP requests asynchronously in the DP MST helpers, fixing
hotplug notifications and allowing us to implement suspend/resume
reprobing
* Add basic suspend/resume reprobing to the DP MST helpers
* Improve locking for link address reprobing and connection status
request handling in the DP MST helpers
* Miscellaneous refactoring in the DP MST helpers
* Add a Kconfig option to the DP MST helpers to enable tracking of
gets/puts for topology references for debugging purposes
Driver Changes:
* nouveau: Resume hotplug interrupts earlier, so that sideband
messages may be transmitted during resume and thus allow
suspend/resume reprobing for DP MST to work
* nouveau: Avoid grabbing runtime PM references when handling short DP
pulses, so that handling sideband messages in resume codepaths with the
DP MST helpers doesn't deadlock us
* i915, nouveau, amdgpu, radeon: Use detect_ctx for probing MST
connectors, so that we can grab the topology manager's atomic lock
Note: there's some amdgpu patches that I didn't realize were pushed
upstream already when creating this topic branch. When they fail to
apply, you can just ignore and skip them.
