[Alsa-devel] SonyPI module and via82xx sound driver
Hi, The sonypi module uses IO Address 0x1080 - 0x1084B, which is in the range of the via82xx sound driver (0x1000 - 0x10ff). Is it possible to exclude the address range of the sonypi module in the via82xx driver? I'm pretty sure that it isn't really used by ALSA :) thanks Markus -- __/"\ Markus Gaugusch \ /ASCII Ribbon Campaign markus(at)gaugusch.at X Against HTML Mail / \ --- This SF.net email is sponsored by: IBM Linux Tutorials.

Unfortunately, the region is shown with 256 bytes: 00:07.5 Multimedia audio controller: VIA Technologies, Inc. VT82C686 AC97 Audio Controller (rev 50) Subsystem: Sony Corporation: Unknown device 80f6 Flags: medium devsel, IRQ 5 I/O ports at 1000 [size=256] I/O ports at 1c54 [size=4] I/O ports at 1c50 [size=4] Is there any hope for a fix?

(this driver already has two different hacks with subsystem id checks.) Takashi --- This SF.net email is sponsored by: IBM Linux Tutorials. Become an expert in LINUX or just sharpen your skills.
