Re: cassiopeia for DoCoMo

鈴木(康)です。
<200002251337.WAA07559@ninja.hpc.bs1.fc.nec.co.jp>の記事において
suz@hpc.bs1.fc.nec.co.jpさんは書きました。

  | 鈴木(康)です。
  | 
  | カシオペアでいろいろやっているんですが、割り込み回り
  | なかなかうまくいかないです。

やっとうまくいきました。

  | linuxce のほうで 湯浅さんから
  | 
  | 
  |   IRQの40-71(GIU interrupt 0-32)のどれかに割り込みが入ったときは、
  |   IRQの16(System interrput 8)にも割り込みが入ります。
  |   pollingではありません。
  | 
  | と教えていただいたので

これやっぱり正しかったです。

カシオペアの割り込みは全部

VRGIU＿INTR＿LEVEL＿LOW＿THROUGH

みたいです。

# ボタンが active low であることから、もっと早く気が付いても
# 良かったのに と思いました。


  | 0 番の GIU を開けるようにしてみたんですが、
  | 割り込みが入りつづけてしまいます。

だからこうなってしまったわけでした。


というわけで、

config を

vrisab4 at vrgiu? platform CASIO_CASSIOPEIAE_E55 isaportoffset 0xc000
isa4    at vrisab4
wdc0    at isa4 port 0x170 irq 0x0020000f

という風にしています。

irq は、32 -> 0 に見なすように vrgiu.c をちょっと修正して、

あと、とりあえず以下のところ ハードコーディングしています。


mode = VRGIU_INTR_LEVEL_HIGH_THROUGH;  /* XXX Is this OK? */
->
mode = VRGIU_INTR_LEVEL_LOW_THROUGH;  /* XXX Is this OK? */
