[9fans] JVC Netbook works fine, except PCMCIA

[9fans] JVC Netbook works fine, except PCMCIA

[Frederik Caulier]

Hello 9fans

Just wanted to let you know that Plan 9 runs fine (except for a
PCMCIA-related problem, see below) on my JVC MP-XP3 Netbook.

I installed Plan 9 using the latest ISO-Image ("Dec 14 2009") which I
downloaded yesterday.

System: JVC MP-XP3

Intel Pentium III (750 MHz)
SIS 630 with VGA, LAN* and onboard AC'97 sound (on chip it says "SIS
630 ST", RAM shares up to 64MB with VGA)
256 MB RAM (can be upgraded to more)
Ricoh 475 PCMCIA Controller (recognized on boot)
80 GB Fujitsu IDE-HDD (5200 RPM)
8,9" display with native resolution of 1024x600 pixels

(*LAN is recognized as "ns83815" on port d400/d4ff, but it's broken
because my predecessor plugged in a bad cable.)

The ps2 trackpoint and the three onboard mouse buttons work just fine
out of the box.

The following resolutions work with the VESA driver:

800x600x32
800x600x16
800x600x8

I tried using 1024x600x8 but it didn't work, rio complains about
something with the vgadb.

Is there a way how I can nevertheless use this resolution?


Right now I'm trying to use my D-Link DFE-690TXD PCMCIA-Card (Realtek
rtl8139) but I encounter some difficulties. According to the Wiki it
should be supported.

First problem:
------------------

% ip/ipconfig
ipconfig: /net/ipifc/clone: bind ether /net/ether0: '/net/ether0' cs:
file does not exist

Second problem:
----------------------

The system boots fine with the PCMCIA card in the slot only once, on
the following boot it always does the usual startup but then hangs at
"init: /bin/rc". (Note that it is not related to the device waiting
for a DHCP offer as I once waited a long time and still nothing
happened.) So I have to reboot, edit and save ANY setting in the BIOS
and then boot again, now the system will work again and boot with the
PCMCIA card.

% cat /n/9fat/plan.ini
bootfile=sdC0!9fat!9pcf
bootargs=local!#S/sdC0/fossil
bootdisk=local!#S/sdC0/fossil

pcmcia0=type=rtl8139 port=0x400 irq=10
ether0=rtl8139

# *debugload=1
# *noahciload=1
# [debug]
*nobiosload=1
*nodumpstack=1
*nomp=1

dmamode=ask
partition=new
mouseport=ps2
vgasize=800x600x32
monitor=vesa

Notes: Whether I change the port/irq, remove port/irq, remove the
complete pcmcia0= line doesn't change anything. Also, whether trying
with or without ether0=rtl8139 doesn't change anything.

The following is what I get on boot:

[...]

3f7	3f7 floppy
400	5ff cardbus # This is the concerned card.
fff	fff dummy
d400	d4ff ns83815

Notes: The card always appears on port 400 and the settings in
plan9.ini are ignored. For example, if I write port=0x380 in plan9.ini
this will still appear on port 400.

I found a few messages with similar issues on 9fans but they didn't
really help me.

Try editing /lib/vgadb and adding "xga=1024x600"

Nope.  "pcmcia0" tells the kernel what kind of PCMCIA
bridge you have; since you have CardBus (which is better),
you shouldn't have one of those lines unless you need to
disable the CardBus driver and use the old PCMCIA code
instead.  One reason to do that, by the way, is that the
PCMCIA bridge driver accepts an IRQ override (for the
bridge itself) and the CardBus driver doesn't.  I have
one Sony Vaio whose BIOS sets *all* IRQ's to 9, which
results in sadness, so I use the PCMCIA driver instead
of the CardBus driver.

> ether0=rtl8139

This is also wrong.  You want "ether0=type=rtl8319".

Can you send us the output of "aux/pcmcia"?  Also of
"cat /dev/ioalloc"?

good catch.  it should be "ether0=type=rtl8139"
though.  one should not need this oft mis-typed
line unless
- you wish to force the a particular ordering of controller
types.  say you want the rtl8139 to be the first controller
and, say, a 83815 to be the second.  i use this on some machines
to force the myricom card to be eth0.
- you need to specify more information, like an ea or
an irq.
- you're using ken's fileserver.

Re: [9fans] JVC Netbook works fine, except PCMCIA

[Frederik Caulier]

I just booted without any "ether0=" and "pcmcia0=" lines and the
problem persists.

Only change is that on boot I see "rtl8139: port 0x400 in use" only
once and not two times as I mentioned in my previous message.

I appreciate your help very much.

Ok, I completely removed the "pcmcia0=" entry and booted only with
"ether0=type=rtl8139" as you told me.

This is what I get on boot, note that the the change is that now I get
"rtl8139: port 0x400 in use" two times.

I think I've seen this before.  A year ago I was trying to get
a LinkSys pseudo-Tulip CardBus card working.  Before I gave up,
I ran into a situation where the CardBus driver was allocating
a hunk of I/O space for the card but the card was later unable
to use the space.  At that time I convinced myself that the
problem was in ioalloc(), around line 230 of devarch.c.  This
is what I did at the time, though I never submitted it as a
patch since I wasn't able to prove it was right by getting the
card to work, plus which I wasn't sure I was fully understanding
the code.

-  if(m->reserved && m->start == port && m->end == port + size) {
+  if(m->reserved && m->start == port && m->end >= port + size) {

Hello

I just recompiled the kernel with your suggested modification in line
239 of the /sys/src/9/pc/devarch.c file.

Good news:
The "port 0x400 in use" disappeared and the rtl8139 PC Card is now
correctly recognized as:
#l0: rtl8139: 10Mbps port 0x400 irq 11: 001b1159be56
(LEDs are active)

Bad news:
When booting the system with the rtl8139 PC Card plugged in the kernel
crashes on boot.

Here's what I get on boot when the card is plugged in:

[...]
cpu0: 748MHz GenuineIntel Pentium III/Xon (cpuid: AX 0x06B1 DX 0x383F9FF)
ELCR: 08B0

When booting the new, modified kernel without the rtl8139 pc card
being plugged in the system boots just fine.

Help on how to fix this is very welcome.

i'm pretty sure that vesa gets its modes from the vesa bios.
i think the setting monitor=vesa might solve this problem.
