yesterday i finnaly finished debuging for amdgpu , i found the suspend and resume function not work for freebsd 12.1 drm5.0 ,because the linuxkpi_register_pci_drm_driver won't get suspend and resume callback .
the problem is linuxkpi compilation option is incorrect by default caus linuxkpi.ko lost some member variable of struct , amdgpu drm 5.0 driver use linuxkpi version more then 50000 .
before do following step , you have to install amdgpu drm5.0 driver for freebsd 12.1, read this thread

to solve this issus, you shoud change /usr/src/sys/modules/linuxkpi/Makefile like this:
#########START############## <--- do not copy this line

this Makefile only use for drm 5.0 driver
and then compile linuxkpi and install it. just do this
put this in your /etc/sysctl.conf to close lid for suspending
to test it ,just close your laptop lid , it works fine for amd r3500u vega8
you need restart your laptop before testing it
how to check does it work?
look at your laptop power indicator led, it will be blinking slowly.
