Building a randconfig here triggered:
ERROR: modpost: "pm_suspend_target_state" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
because the module export of that symbol happens in
kernel/power/suspend.c which is enabled with CONFIG_SUSPEND.
The ifdef guards in amdgpu_acpi_is_s0ix_supported(), however, test for
CONFIG_PM_SLEEP which is defined like this:
config PM_SLEEP
def_bool y
depends on SUSPEND || HIBERNATE_CALLBACKS
and that randconfig has:
# CONFIG_SUSPEND is not set
CONFIG_HIBERNATE_CALLBACKS=y
leading to the module export missing.

This patch limits the ref_div_max value to 100, during the
calculation of PLL feedback reference divider. With current
value (128), the produced fb_ref_div value generates unstable
output at particular frequencies. Radeon driver limits this
value at 100.
On Oland, when we try to setup mode 2048x1280@60 (a bit weird,
I know), it demands a clock of 221270 Khz. It's been observed
that the PLL calculations using values 128 and 100 are vastly
different, and look like this:
+------------------------------------------+
|Parameter |AMDGPU |Radeon |
| | | |
+-------------+----------------------------+
|Clock feedback | |
|divider max | 128 | 100 |
|cap value | | |
| | | |
| | | |
+------------------------------------------+
|ref_div_max | | |
| | 42 | 20 |
| | | |
| | | |
+------------------------------------------+
|ref_div | 42 | 20 |
| | | |
+------------------------------------------+
|fb_div | 10326 | 8195 |

|fb_div | 1024 | 163 |
+------------------------------------------+
|fb_dev_p | 4 | 9 |
|frac fb_de^_p| | |
+----------------------------+-------------+
With ref_div_max value clipped at 100, AMDGPU driver can also
drive videmode 2048x1280@60 (221Mhz) and produce proper output
without any blanking and distortion on the screen.
PS: This value was changed from 128 to 100 in Radeon driver also, here:

In preparation for LIBNVDIMM to manage labels on CXL devices deploy
helpers that abstract the label type from the implementation. The CXL
label format is mostly similar to the EFI label format with concepts /
fields added, like dynamic region creation and label type guids, and
other concepts removed like BLK-mode and interleave-set-cookie ids.
CXL labels do have the concept of a claim class represented by an
"abstraction" identifier. It turns out both label implementations use
the same ids, but EFI encodes them as GUIDs and CXL labels encode them
as UUIDs. For now abstract out the claim class such that the UUID vs
GUID distinction can later be hidden in the helper.
