This patch allows panel orientation quirks from DRM core to be
used. They attach a DRM connector property "panel orientation"
which indicates in which direction the panel has been mounted.
Some machines have the internal screen mounted with a rotation.
Since the panel orientation quirks need the native mode from the
EDID, check for it in amdgpu_dm_connector_ddc_get_modes.

This was unusual; normally, inline functions are declared static as
well, and defined in a header file if used by multiple compilation
units. The latter would be more involved in this case, so just drop
the inline declaration for now.

Current RUNPM mechanism relies on PMFW to master the timing for BACO
in/exit. And that needs cooperation from sound driver for dstate
change notification for function 1(audio). Otherwise(on sound driver
missing), BACO cannot be kicked in correctly and hang will be observed
on RUNPM exit.
By switching back to legacy message way on sound driver missing,
we are able to fix the runpm hang observed for the scenario below:
amdgpu driver loaded -> runpm suspend kicked -> sound driver loaded

[Why]
call stack of amdgpu dsc mst pbn, slot num calculation is as below:
-compute_bpp_x16_from_target_bandwidth
-decide_dsc_target_bpp_x16
-setup_dsc_config
-dc_dsc_compute_bandwidth_range
-compute_mst_dsc_configs_for_link
-compute_mst_dsc_configs_for_state
from pbn -> dsc target bpp_x16
bpp_x16 is calulated by compute_bpp_x16_from_target_bandwidth.
Beside pixel clock and bpp, num_slices_h and bpp_increment_div
will also affect bpp_x16.
from dsc target bpp_x16 -> pbn
within dm_update_mst_vcpi_slots_for_dsc,
pbn = drm_dp_calc_pbn_mode(clock, bpp_x16, true);
drm_dp_calc_pbn_mode(int clock, int bpp, bool dsc)
{
return DIV_ROUND_UP_ULL(mul_u32_u32(clock * (bpp / 16), 64 * 1006),
8 * 54 * 1000 * 1000);
}
bpp / 16 trunc digits after decimal point. This will cause calculation
delta. drm_dp_calc_pbn_mode does not have other informations,
like num_slices_h, bpp_increment_div. therefore, it does not do revese
calcuation properly from bpp_x16 to pbn.
pbn from drm_dp_calc_pbn_mode is less than pbn from
compute_mst_dsc_configs_for_state. This cause not enough mst slot
allocated to display. display could not visually light up.
[How]
pass pbn from compute_mst_dsc_configs_for_state to
dm_update_mst_vcpi_slots_for_dsc

On Carrizo/Stoney systems we set backlight through panel_cntl, i.e.
directly via the PWM registers, if DMCU is not initialized. We
always read it back through ABM registers which leads to a
mismatch and forces atomic_commit to program the backlight
each time.
Instead make sure we use the same logic for backlight readback,
i.e. read it from panel_cntl if DMCU is not initialized.
We also need to remove some extraneous and incorrect calculations
at the end of dce_get_16_bit_backlight_from_pwm.

On some GPUs the PCIe atomic requirement for KFD depends on the MEC
firmware version. Add a firmware version check for this. The minimum
firmware version that works without atomics can be updated in the
device_info structure for each GPU type.
Move PCIe atomic detection from kgd2kfd_probe into kgd2kfd_device_init
because the MEC firmware is not loaded yet at the probe stage.

Add manual sclk/vddc setting supoort via pp_od_clk_voltage sysfs
to maintain consistency with other asics. As cyan skillfish doesn't
support DPM, there is only a single frequency and voltage to adjust.
v2: maintain consistency and add command guide.
v3: adjust user settings storage and coding style.
Command guide:
echo vc point sclk vddc > pp_od_clk_voltage
"vc" - sclk voltage curve
"point" - must be 0
"sclk" - target value of sclk(MHz), should be in safe range
"vddc" - target value of vddc(mV), a 6.25(mV) stepping is
recommended and should be in safe range (the real
vddc is an approximation of target value)
echo c > pp_od_clk_voltage
"c" - commit the changes of sclk and vddc, only after
the commit command, the target values set by "vc"
command will take effect
echo r > pp_od_clk_voltage
"r" - reset sclk and vddc to default value, a subsequent
commit command is needed to take effect
Example:
1) Check default sclk and vddc
$ cat pp_od_clk_voltage
OD_SCLK:
0: 1800Mhz *
OD_VDDC:
0: 862mV *
OD_RANGE:
SCLK: 1000Mhz 2000Mhz
VDDC: 700mV 1129mV
2) Set sclk to 1500MHz and vddc to 700mV
$ echo vc 0 1500 700 > pp_od_clk_voltage
$ echo c > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 1500Mhz *
OD_VDDC:
0: 693mV *
OD_RANGE:
SCLK: 1000Mhz 2000Mhz
VDDC: 700mV 1129mV
3) Reset sclk and vddc to default
$ echo r > pp_od_clk_voltage
$ echo c > pp_od_clk_voltage
$ cat pp_od_clk_voltage
OD_SCLK:
0: 1800Mhz *
OD_VDDC:
0: 874mV *
OD_RANGE:
SCLK: 1000Mhz 2000Mhz
VDDC: 700mV 1129mV
NOTE:
We don't specify an explicit safe range, you can set any values
between min and max at your own risk. Enjoy!

In amdgpu_dm_atomic_check, dc_validate_global_state is called. On
failure this logs a warning to the kernel journal. However warnings
shouldn't be used for atomic test-only commit failures: user-space
might be perfoming a lot of atomic test-only commits to find the
best hardware configuration.
Downgrade the log to a regular DRM atomic message. While at it, use
the new device-aware logging infrastructure.
This fixes error messages in the kernel when running gamescope [1].

KH in the misc tree back in the previous merge window, so only the
cleanup ends up being new to 5.15 - Linus ]

Andre reported fw_devlink=on breaking OLPC XO-1.5 [1].
OLPC XO-1.5 is an X86 system that uses a mix of ACPI and OF to populate
devices. The root cause seems to be ISA devices not setting their fwnode
field. But trying to figure out how to fix that doesn't seem worth the
trouble because the OLPC devicetree is very sparse/limited and fw_devlink
only adds the links causing this issue. Considering that there aren't many
users of OF in an X86 system, simply fw_devlink DT support for X86.

The ret value might be -EBUSY, caller will think lru lock is still
locked but actually NOT. So return -ENOSPC instead. Otherwise we hit
list corruption.
ttm_bo_cleanup_refs might fail too if BO is not idle. If we return 0,
caller(ttm_tt_populate -> ttm_global_swapout ->ttm_device_swapout) will
be stuck as we actually did not free any BO memory. This usually happens
when the fence is not signaled for a long time.
