Thank you. Just unconditionally disabling AGP in R300 initialization made radeonkms to load successfully. It seems that no tunables for FreeBSD are described instead of MODULE_PARM_DESC and module_param_named. So, I have to learn how to add them to the source code. (/usr/src/sys/dev/drm2/os_freebsd.c seem to help.)
Anyway, it worked. thank you. Some problems remain. The virtual screen is larger than the real one and I cannot see the command line I am inputting, and I did not yet test X as there seem to be problems in building them from ports, but that are other things. 2017-03-06 13:03 GMT+09:00 Herminio Hernandez, Jr. <herminio.hernande...@gmail.com>: > Per the radeon man page here.
