I looked at my board, and IRQ 15 is definitely connected to the Jazz16 chip. On to the probing with probe_irq_on() and probe_irq_mask(). If I turn off the secondary IDE port of the legacy-mode PIIX chip, I get jazz16pnp: irq_config 0 -> irq_mask 000000. jazz16pnp: irq_config 1 -> irq_mask 000040 (bit 5 set). jazz16pnp: irq_config 2 -> irq_mask 001000 (bit 9 set). jazz16pnp: irq_config 3 -> irq_mask 000010 (bit 3 set). jazz16pnp: irq_config 4 -> irq_mask 000200 (bit 7 set). jazz16pnp: irq_config 5 -> irq_mask 002000 (bit 10 set). jazz16pnp: irq_config 6 -> irq_mask 000000. jazz16pnp: irq_config 7 -> irq_mask 000000. Setting irq_config 8-15 works just like irq_config 0-7. It only gets weirder with the secondary IDE port enabled: jazz16pnp: irq_config 0 -> irq_mask 0000000. jazz16pnp: irq_config 1 -> irq_mask 0000040 (bit 5 set). jazz16pnp: irq_config 2 -> irq_mask 0001000 (bit 9 set). jazz16pnp: irq_config 3 -> irq_mask 0000010 (bit 3 set). jazz16pnp: irq_config 4 -> irq_mask 0000200 (bit 7 set). jazz16pnp: irq_config 5 -> irq_mask 0002000 (bit 10 set). jazz16pnp: irq_config 6 -> irq_mask 0100000 (bit 15 set). jazz16pnp: irq_config 7 -> irq_mask 0000000. Here IRQ 15 does work.

I've decided to go with this, with the exception that I'll ask for just a 16-bit channel since there is currently little use for the 8-bit one. -- Rask Ingemann Lambertsen _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
