rebooting...

CPUのデータキャッシュ(CPU_CONTROL_DC_ENABLE)をOFFにしたら動いた。
そもそもNetBSDのFA526サポートはちゃんと動いてるのか疑惑ががが

ちなみにdata cache enableのままだと、vmをallocした個所を触ってfaultしてdata_abort_handler内でpmapがTLB埋めてreturnした後、再度同じアドレスでfault、という風にループしてた。
TLB設定した後にcache invalidateしてやればcache enableでも動くんじゃなかろうか。まぁいいや。些末な問題っぽいので後にしよ。
…というか動かなかったのｵﾚｼﾞｬﾈーーーーーーーーーーーーーー!!!!!!!

panic: config_devalloc: star は何かポカしてるだけだろう。
さて、これでやっと割り込みで遊べるお。
