Ok, attached is a really simple client that will allocate 32MB of scatter-gather memory and map a 1MB ring buffer out of that. The "contents" values should always be 0. Build the client with: gcc -O2 -pipe -I/usr/local/include -I/usr/local/include/drm -L/usr/local/lib -ldrm -o drm-test drm-test.c To perform the test, you will need to boot up in console. (No X) Manually kldload the radeon driver and then as root execute drm-test. robert. > > robert. > > > > -- > > Robert Noland > > FreeBSD > > > -- Robert Noland FreeBSD --=-iuQD1r1McNreZk7d9da1--
