[Xen-devel] PCMCIA WLAN success after patching xen
Short description:
I have Amilo M 7400 laptop with 3COM Atmel based PCMCIA WLAN
card.
I managed to get xen-2.0-testing to work with that card, after
applying Keri Frazer''s CARDBUS patch into xen and recompiling the
kernel for driver support.
Wlan speed is normal:
scp copied data with a rate 737KB/s, that equals approximately
with the normal Linux copying speed.
Marko
Seen problems (Linux: Debian Testing, Linux-2.6.9):
- Time consuming to find out correct compilation parameters for 2.6.9 kernel.
- Network connection was lost after the wlan had been idle for a while.
ifdown eth1, ifup eth1 solved the problem.
I don''t know the cause for this. Power management seems to be off
on the WLAN card.
- Apache 2 starts up very slowly. I believe, that Apache waits
for some keyboard input under domain0. That seems to help??
Details about installation:
I tried first the xen-2.0.1, but moved into xen-2.0-testing:
I found out, that the Intel video card might work there with agpgart.
It works for me.
I got the 3COM PCMCIA WLAN (Atmel chipset) to work at the following way:
Apply the patch made by Keri Fraser on mail archive:
http://sourceforge.net/mailarchive/message.php?msg_id=9923531
Here is the patch that I applied into xen-2.0-testing:
xen/common/physdev.c:
On function void physdev_init_dom0(struct domain *p):
Replace the following code:
* In Linux2.6 we set pcibios_scan_all_fns().
*/
if ( dev->hdr_type != PCI_HEADER_TYPE_NORMAL )
continue;
into this code on line 745:
* In Linux2.6 we set pcibios_scan_all_fns().
*/
if ( dev->hdr_type != PCI_HEADER_TYPE_NORMAL &&
dev->hdr_type != PCI_HEADER_TYPE_CARDBUS)
continue;
This really worked!
- cardbus was found.
- Yenta socket was initialized.
- 3COM Atmel card: the firmware was loaded via HotPlug into the PCMCIA card,
and the network card was initialized.
- The netwok just started to work!
It took me lots of time to configure the kernel.
Here are the main kernel configuration parts, that affected the PCMCIA success.

Re: [Xen-devel] PCMCIA WLAN success after patching xen
thanks for tips. I guess I''ll retry the issue. the same patch did not quite work for me.

I guess I''ll re-try it with xen-2.0-testing. I was trying with xen-2.0-beta, so perhaps this makes difference. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Re: [Xen-devel] PCMCIA WLAN success after patching xen
Thank you very much. I noticed also a following thing on installation: It would have helped me on install instructions, if there were some requirement note, that the domain0 must be on a single partition to be able to boot. I managed to start up xen only after repartitioning: I had /, /boot and /usr partitions. Under /boot directory there is some soft links, that point into various places. After moving into one very large root partition, the Domain0 started to boot. -- Marko On Sat, 11 Dec 2004 13:19:25 -0500 (EST) Adam Sulmicki <adam@cfar.umd.edu> wrote:> > thanks for tips.
