Every other case of this I had seen was 128MB, so I was just assuming. Basically the issue (afaik) is that you're running out of KVA because framebuffers are large and KVA isn't all that huge. pmap_mapdev was not designed to handle failure to allocate memory, so it just paniced instead of returning NULL (which wouldn't have helped us anyway, due to other issues). -- Eric Anholt eta_at_lclark.edu http://people.freebsd.org/~anholt/ anholt_at_FreeBSD.orgReceived on Sun Jun 26 2005 - 21:43:02 UTC
