Running 11.2 release with a radeon HD 5550 board,
11.2-RELEASE-p4 FreeBSD 11.2-RELEASE-p4 #0: Thu Sep 27 08:16:24 UTC 2018 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
kldstat shows the following drivers:
radeonkms.ko
radeon_REDWOOD_pfp_bin.ko
radeon_REDWOOD_me_bin.ko
radeon_REDWOOD_rlc_bin.ko
radeon_REDWOOD_smc_bin.ko
radeon_CYPRESS_uvd_bin.ko
Things seem to be running fine but I am getting the following errors
in my security log:
+fence_wait returned with error -512
Can anyone explain to me what these are about?
I found this thread:
http://freebsd.1045724.x6.nabble.com/drm2-in-base-td6284182.html
but it's not clear to me what the fence is and what fence_wait is all
about.
Thanks,
Gary
