Hello list,
did anyone (Jason ???) have time to look into the ahb /Jensenio/EiSA
driver.
I had tracked down the problem on not getting a valid return on the irq
status
in the 1742 driver irq routine:
if ((bus_space_read_1(iot, ioh, G2STAT) & G2STAT_INT_PEND) == 0)
return 0;
/* this point is never reached ! */
always receives a 0 status and thus always returns without doing
anything or clearing the interrupt. I have the Jensen manual but I
really do not know where to start looking for the problem (Problems with
the EISA bus code ???).
All pointers appreciated !
Hans-Jürgen
