| |
I have a IAC-H553 Board with a NS Geode Low-Power CPU:
Working around Cyrix MediaGX virtual DMA bugs. Enable Memory-Write-back mode on Cyrix/NSC processor. Enable Memory access reorder on Cyrix/NSC processor. Enable Incrementor on Cyrix/NSC processor. CPU: After all inits, caps: 00808131 00818131 00000000 00000001 CPU: Cyrix Geode(TM) Integrated Processor by National Semi stepping 02 Checking 'hlt' instruction... OK. with a chipset CS5530A Geode.
I have also a Digital Input Output card, and I have develop a board to generate an interrupt when and input change.
This has been working under MS-DOS properly, but in Linux i lose some interrupt (I do not get my isr routine called and in /proc/interrupts the counter do not increment).
If I use the same Digital Input Output card whit another CPU and linux everithing work property.
Have someone find the same problem with Geode?
I use the kernel 2.6.5 from debian with Preemtive.
I am nos suscribe to the kernel list, so please response also to my email.
Thanks in advance
