Subject: PCI IRQ Steering under Linux?
Date: Wed, 07 Mar 2001 21:05:55 GMT
Does Linux support PCI IRQ steering (as in Windoze)? I can't get a
clear answer from the Red Hat support site, the LDP site, or the Web
in general. I don't even know if it's a stupid question :-(
The reason I need to know is that my Asus A7V mobo shares the IRQ for
each PCI slot with things such as the ATA100 controller (and this
feature seems to be non-negotiable). This means in particular that
my Netgear FA310 network card and its IRQ (10) is recognised by the
Linux kernel on boot-up, but the card won't work because of a conflict
with the ATA100 controller's use of IRQ 10. The only way of getting
an unshared IRQ for the card is to disable the ATA100 controller, and
I don't really want to do that. A similar problem would occur on the
other PCI slots, so there seems to be no point in shuffling the card
around.
I'm warm-booting to Red Hat 7.0 (kernel 2.2.16) via LOADLIN from DOS
(don't know if this is relevant). The "PnP OS" BIOS value is set to
"no".
Any info gratefully received.

Indeed. If it doesn't (many don't, mine certainly doesn't) you
might want something like:
----- box (Linux)
|
cable ------ Linux[1] ------ Hub --- box (Win)
modem |
----- box (Win)
[1] - NAT + firewall of some kind (doesn't have to be Linux, could be
*BSD); hardware requirements are minimal

Does Redhat 7.0 have rescue mode boot from the install CD? If it does
and you can get to a command prompt and mount your root partition on,
say, /mnt then you can run
/sbin/lilo -r /mnt
and it'll chroot to /mnt (making /mnt appear as / to the command) and
then read /etc/lilo.conf from your current setup and reinstall itself.
No need to reinstall at all.

Ok, here goes. I am currently running Slackware 7.0 with kernel 2.2.18,
i have a Genius modem with a Lucent chipset that is supported, i have
the drivers for this chipset. When i have installed the drivers as the
README states, i try connecting to the net with wvdial. It dials the
number ok, and you hear the dialtone etc, but then pppd dies! I am
running the standard ppp version that comes with Slack 7.0, version
2.3.10.
But thats not all, i have run Suse 7.0 with kernel 2.2.18, with same ppp
version, and installed drivers *exactly* the same, and i have managed to
connect ot the net, everything is fine.
Why not run Suse i hear you say. Well, and this is weird, my original
Sounblaster 16 (that is its not just a SB16 chipset, its an actual
Creative Labs card) doesnt get detected! I have tried compiling it in as
a module, and also not as a module in the kernel, but neither work! I
dont know why!
Any help on this matter would be GREATLY appreciated, as i am sick to
death of windoze crashing, and those god-awful blue screens of death. I
may just buy an external modem, seeing as i can afford to now, but if i
can get my current one working that would be better, plus its a
challenge :)
Thanks

I use a Logitech wireless keyboard and mouse, works fine.
The receiver box plugs into the PS/2 keyboard and mouse ports
and it looks to the system just like any other.

My Linux server (Mandrake 7.2) has an FA311 installed, once I used the new

Erh.. Does the Linux[1] box down there need 4 NIC then? one to cable modem,
one to hub and other two for two boxes.

I would recommend using the command: "/sbin/ifconfig | grep HWaddr" to get the
hardware address. You can then use the utilities like sed and awk to actually
strip out the address without all of the other stuff in front of it.

The linux kernel, being an entity that values YOUR privacy,
disables access to the CPUid by default. You will need to
recompile most kernels to enable access.

This is the right one if you set up firewall capability on the Linux
box. The cable modem probably has no firewall capability. This requires
two NICs in the Linux box.
If you don't want to make the Linux box a firewall, then you could
do this:
cable modem ---- FW Box --- Hub --- Windows
|
*----- Linux
Where "FW Box" could be an off-the-shelf firewall/router ($99).
They're generally easy to configure. Or use a spare 486 with
Linux on it configured for firewall/routing.
I highly recommend having a firewall somewhere if you don't
want to get hacked easily.

Subject: Re: poll_wait and interruptible_sleep_on
Date: Wed, 07 Mar 2001 22:39:02 GMT
Hi Michael,
Thanks you very much on answering all my questions. With you cooperation,
I've got the basic driver working. I've included some piece of code to help
you understading my issues.
1. I've to be able to report the interrupt status to user, since I don't
know how much data has been written on the bridge memory (My driver is used
on the primary bus side of the bridge, secondary bus side is a different env
(VxWorks in this case). And the app level protocol between 2 sides will have
the knowlede for the data content. Do you think it is the right approach
still (or still a broken design)
2. As you mentioned poll_wait does return right away. The tried with my test
code (app side) that user gets the response right away (even though my
driver did not issue any wake up call). This is with case when user called
system poll command only for my device. kernel did invoke my poll routine.
And poll_wait return right away. Since I did not get any interrupt status
change, driver did not call any wake, but still user did not goto the wait
mode. WHY?
3. So I tried something different, provided an IOCTL call to be able to wait
till interrupt is changed. This time I called interruptible_sleep_on method
on the same queue. And the IOCTL call kept the user in the wait mode, until
driver called the wake_up call. So, I got the desired result.
4. Please review my code (if possible) and suggest me what is wrong, why the
poll method does not work.
5. It seems like the interruptible_sleep_on did the trick. Shall I use this
in my poll command also.
6. I'm still little fuzzy about the interruptible_sleep_on and poll_wait
difference.
Thanks

I'm waiting for an encrypted wireless keyboard.

It is possible you have an authentication failure dumping you after it
connects. Most ISP's use PAP, some use CHAP. Check the files
/etc/ppp/pap-secrets and chap-secrets. Both of these files must be
readable only by root. They contain password info that is needed *after*
the normal login. PAP uses it once after login, CHAP uses it at random
intervals. Some of it is explained in the man page for pppd. A sample
line would be:
some_login_name * some_password

One, there can be hardware setup issues for ISA, or ISA PNP, or PCI,
that are not due to this being a SB16. There can also be sound setup
issues, after hardware setup issues are out of the way. Some
clarification is that each card generally has an irq and base address.
Some have more, such as sound cards having DMA addresses, and multiple
base addresses since it also supports a joystick port. In the case of a
pure ISA card, this will be set on the card with jumpers, and software
will have to be told what irq and address to use. In the case of a
Plug-n-Play (PNP) ISA card, the software side has the same requirement,
but the hardware is programmed with software also, instead of manual
jumpers. For this isapnptools are used, e.g., check out isapnpdump and
the file /etc/isapnp.conf. In the case of a PCI card, it has internal
information to aid the system in making all of those settings for you.
But, you should try to set your BIOS, during bootup, to "operating
system is NOT plug-n-play aware"; this means the BIOS will try to set up
the hardware before your system sees it (the system can still manipulate
it, but it is better if the BIOS can help avoid some of it). The system
is more likely to detect and set (through various distribution setup
scripts) a PCI card right, especially if the BIOS setting is "not pnp
aware", although it may still require intervention sometimes.
If the hardware is correctly initialized, then modules or other sound
setup can succeed. I can't help much with this particular card, but you
will be at an advantage if you set BIOS to not pnp aware, and find out
if this is a jumpered ISA card, ISA PNP, or PCI. If you post more
questions, be sure to state which kind of card it is.

Yep, but don't expect any Linux support. Of course, I'm biased
