drm/amd/display: NULL pointer hang

[Why]
In dc_link_dp_set_test_pattern, we assume all pipes have a stream, which
can cause null pointer dereference.

[How]
Add a null pointer check before accessing stream.

drm/amd/pm: modify the fine grain tuning function for Renoir

This patch is to improve the fine grain tuning function for Renoir.
The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage
to config gfxclk. Meanwhile, another sysfs
node -- power_dpm_force_perfomance_level also affects the gfx clk.
It will cause confusion when these two sysfs nodes works
together.
And the flag "od_enabled" is used to control the overdrive function for
dGPU, like navi10, navi14 and navi21.
APU like Renior or Vangogh uses this "od_enabled" to configure
the frequency range of gfx clock, but the max value of frequency
range will not be higher than the safe limit, it is not "overdrive".
So this patch adds two new flags -- "fine_grain_enabled" and
"fine_grain_started" to avoid this confusion, the flag will
make these two sysfs nodes work separately.
The flag "fine_grain_enabled" is set as "enabled" by default,
so the fine grain tuning function will be enabled by default.
But the flag "fine_grain_started" is set as "false" by default,
so the fine grain function will not take effect until it is set as
"true".
Only when power_dpm_force_perfomance_level is changed to
"manual" mode, the flag "fine_grain_started" will be set as "true",
and the fine grain tuning function will be started.
In other profile modes, including "auto", "high", "low", "profile_peak",
"profile_standard", "profile_min_sclk", "profile_min_mclk",
the flag "fine_grain_started" will be set as "false", and the od range of
fine grain tuning function will be restored default value.

drm/amdgpu: Add check to prevent IH overflow

Similar to commit <81ce6b9e81d6>("drm/amdgpu: fix IH overflow on Vega10 v2").
When an ring buffer overflow happens the appropriate bit is set in the WPTR
register which is also written back to memory. But clearing the bit in the
WPTR doesn't trigger another memory writeback.

So what can happen is that we end up processing the buffer overflow over and
over again because the bit is never cleared. Resulting in a random system
lockup because of an infinite loop in an interrupt handler.

drm/amdgpu/display: drop DCN support for aarch64

From Ard:

"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.

So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."

Disable support until the code can be properly refactored to support this
properly on aarch64.

drm/amd/display: enable idle optimizations for linux (MALL stutter)

[Why]
We can only use this feature when the display is idle. When active vblank
irq count is 0 we know all the displays are idle.

[How]
-Add a active vblank irq counter
-Update the counter when we enable/disable vblank irq
-if vblank irq count is 0 we can consider mall stutter

drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCO

This patch is to improve the fine grain tuning function for RV/RV2/PCO.
The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage
to config gfxclk. Meanwhile, another sysfs
node -- power_dpm_force_perfomance_level also affects the gfx clk.
It will cause confusion when these two sysfs nodes works
together. So this patch adds one flag to avoid this confusion, the flag
will make these two sysfs nodes work separately.
The flag is set as "disabled" by default, so the fine grain tuning function
will be disabled by default.
Only when power_dpm_force_perfomance_level is changed to
"manual" mode, the flag will be set as "enabled",
and the fine grain tuning function will be enabled.
In other profile modes, including "auto", "high", "low",
"profile_peak", "profile_standard", "profile_min_sclk",
"profile_min_mclk", the flag will be set as "disabled",
and the od range of fine grain tuning function will
be restored default value.

drm/amd/pm: add support to umd P-state function for vangogh

This patch is to add support to umd P-state function for vangogh.
It enables the "set" function of 3 sysfs nodes: pp_dpm_mclk,

This patch is to add the fine grain tuning function for renoir.
This function uses the pp_od_clk_voltage sysfs file to configure the min

Command guide:
echo "s level value" > pp_od_clk_voltage
        "s" - set the sclk frequency
        "level" - 0 or 1, "0" represents the min value,  "1" represents

        auto
        $ echo "profile_standard" > power_dpm_force_performance_level
