[irda-users] [PATCH2.6] nsc-ircc to platform device + suspend/resume redo

[Rudolf Marek <r.marek@sh...>]

Hello all,

I have never been able to get the nsc-ircc driver working after
resume. As the result I developed a patch that convert driver
to platform_driver stuff plus it adds a working resume for me.

The patch is not yet to be included. What I want is some test/comment
from nsc-ircc users/irda developers.

I know it works for SIR transfers up to 115K.  I dont have any faster device
so I cant test it...

Please can someone do some tests with the patch?

I would like to know if I need to call .._change_speed
even when the device was down to provide some defined state
of those registers, I'm setting speed to 9600.

Good would be if someone can comment the progranm logic.

The patch was a bit inspired by smsc irda driver. If all will
go well I will prepare more cleaner patch for inclusion.

The patch is against 2.6.15-rc6

Thank you,
Regards
Rudolf

[irda-users] net/irda/irnet/irnet_irda.c:699: warning: array subscript out of range

[d binderman <dcb314@ho...>]

Hello there,

I recently tried out a non standard version of the GNU C compiler on the
2.6.14.4 Linux kernel. The compiler said

net/irda/irnet/irnet_irda.c:699: warning: array subscript out of range

The source code is

      self->rname[NICKNAME_MAX_LEN + 1] = '\0';

but

>find net -name \*.h -print | xargs fgrep rname | more
net/irda/irnet/irnet.h:  char                   rname[NICKNAME_MAX_LEN + 1];

Here is an untested patch to shut up the compiler.

[irda-users] can't get irda to work on a TECRA M1

[Louis-Benoit JOURDAIN <thelbj@gm...>]

Hi,

I'm using:
>uname -a
Linux louve 2.6.9-gentoo-r1 #7 Fri Nov 18 15:02:07 CET 2005 i686
Intel(R) Pentium(R) M processor 1400MHz GenuineIntel GNU/Linux

in modules.conf, I have:
alias irda0 smsc_ircc2

I run the following commands in this order:
- smcinit -v -f 0x0130 -s 0x2f8 -d1 -i3
- modprobe smsc_ircc2

That loads the driver correctly:
Dec 21 11:37:00 louve kernel: NET: Registered protocol family 23
Dec 21 11:37:00 louve kernel: found SMC SuperIO Chip (devid=3D0x5a

pin select
Dec 21 11:37:00 louve kernel: IrDA: Registered device irda0

And I can see the interface is configured:
>/sbin/ifconfig irda0
irda0     Link encap:IrLAP  HWaddr 65:64:08:04
         NOARP  MTU:2048  Metric:1
         RX packets:0 errors:0 dropped:0 overruns:0 frame:0
         TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

         RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
         Interrupt:3 Base address:0x130

Now, I irattach irda0:
Dec 21 11:38:56 louve irattach: executing: '/sbin/modprobe irda0'
Dec 21 11:38:56 louve irattach: executing: 'echo louve >

Dec 21 11:38:56 louve irattach: Starting device irda0

I can see the interface is up:
>/sbin/ifconfig irda0

         RX bytes:0 (0.0 b)  TX bytes:30 (30.0 b)
         Interrupt:3 Base address:0x130

setserial says:
>setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
>setserial /dev/ttyS1
/dev/ttyS1, UART: unknown, Port: 0x02f8, IRQ: 3

But, irdadump reports nothing. It looks like it's not configured properly.
I put my phone in front of the irda receiver, nothing is being filtered.

Should irdadump report something?

Then, I load the drivers for ircomm_tty (in modules.conf, I have:
alias tty-ldisc-11 irtty
alias char-major-161 ircomm_tty)

and I try to sync my pilot by irda on /dev/ircomm0, it doesn't work.

The smcinit page says the sir port is supposed to be on 0x3f8.
Whenever I configure the port with smcinit to 0x3f8 and then I try to
load the module smsc_ircc2, it fails with:
Dec 21 11:23:09 louve kernel: NET: Registered protocol family 23
Dec 21 11:23:09 louve kernel: found SMC SuperIO Chip (devid=3D0x5a
rev=3D00 base=3D0x002e): LPC47N227
Dec 21 11:23:09 louve kernel: smsc_superio_flat(): fir: 0x130, sir:
0x3f8, dma: 01, irq: 3, mode: 0x8a
Dec 21 11:23:09 louve kernel: smsc_ircc_present: can't get sir_base of 0x3f=
8

So I think my ports are good.

Any idea what is going wrong with my settings?

Thanks a lot in advance,

LB

After a weeks worth of googling I have found the following...

setserial /dev/ttyS3 uart none
modprobe smsc_ircc2
irattach irda0 -s
ifconfig irda0 up

And irdadump is showing output from my cell phone...

Looks like You use vanilla kernel, so check Your .config at
#
# Library routines
#
CONFIG_CRC_CCITT=m
CONFIG_CRC32=y
CONFIG_LIBCRC32C=m
...

Pre-load crc-ccitt module or recompile kernel with build-in CRC routines

Hi!

[irda-users] smsc-ircc2 on a dell latitude cpi a366st

[Andrew \ruskie\ Levstik <ruskie@ma...>]

I'm having problem getting this to work on my latitude cpi a366st laptop.
I'm running:

Linux 2.6.13 hand built vanilla

The chip reported by the smsc-ircc2 driver is:
found SMC SuperIO Chip (devid=3D0x09 rev=3D01 base=3D0x03f0): FDC37N958FR
Revision higher than expected

The BIOS is configured to set the irda to com4 so ttyS3.
dmesg | grep "ttyS3" returns the following:
ttyS3 at I/O 0x2e8 (irq =3D 3) is a 16550A

Someone please help...
