I wondering if I'm missing something here. I had PCMCIA stuff working
for a NE2000 ethernet card but not for serial ports. Does anyone have
serial ports working (ie. modems or serial cards)? I had this laptop
working with 3.1 and just upgraded it to current and the serial port
stopped working.
Here is what is reported from pccardd:
May 28 09:00:01 770z /kernel: Card inserted, slot 0
May 28 09:00:06 770z pccardd[1428]: Using I/O addr 0x3e8, size 8

May 28 09:00:11 770z pccardd[1428]: driver allocation failed for Xircom
Significant boot messages:
May 28 08:11:14 770z /kernel: PC-Card Intel 82365 (5 mem & 2 I/O windows)
May 28 08:11:14 770z /kernel: pcic: controller irq 3
May 28 08:11:14 770z /kernel: Initializing PC-card drivers: ed xe
Looking at the code /sys/pccard/pccard.c:
static int
allocate_driver(struct slot *slt, struct dev_desc *desc)
{
struct pccard_devinfo *devi;
struct pccard_device *drv;
int err, irq = 0, s;
drv = find_driver(desc->name);
printf("Found driver %s,%p\n",desc->name,drv); /*DJA DEBUG*/
if (drv == 0)
return(ENXIO);
Is returning not found since it is not in the list of "Initializing
PC-card drivers: ed xe". Confirmed by my debug printf.
grep sio /sys/i386/conf/files.i386, returns
isa/sio.c optional sio device-driver
Looking at /sys/isa/sio.c, line 96 on:
#if 0
#include "card.h"
#if NCARD > 0
#include <sys/module.h>
#include <pccard/cardinfo.h>
#include <pccard/slot.h>
#endif
#if NPNP > 0
#include <i386/isa/pnp.h>
#endif
#endif
In 3.1 the laptop used /sys/i386/isa/iso.c and this code was not ifdef'ed out.
This change appears to be part of the new-bus stuff with the changes
narrowed down to
i386/conf/files.i386 rev 1.236
isa/sio.c rev 1.216
So to me this looks like work to be done, ie. convert the pccard stuff to
call new-bus drivers or some capatibility layer needs to be done or I'm
smoking dope.
Thanks,
Doug A.
