sis190/191 gigabit ethernet driver

Submitted by nothing
on March 10, 2005 - 3:42pm

Hey, don't mean to waste anyone's time or anything, but i cannot seem to find the sis 190/191 gigabit ethernet adapter either in the menuconfig, .config, or drivers/net/. I've seen it mentioned in multiple change logs, and this url has it mentioned, but it isn't at the spot indicated there in the 2.6.11 kernel. Will I have to downgrade for this support or what? I have searched sis.com and asus.com (it's an integrated nic on a k8s-mx mobo for my new athlon64 2800+) but have found nothing but windows drivers there :\. Any help regarding this would be highly appreciated, thanks.

well, i've managed to find go

well, i've managed to find google results for it up to as recent as 2.6.10 but I still cannot find the sis190 driver source in the source tree....feel free to offer any suggestions :\ thanks

are you sure it is a SiS190?

http://usa.asus.com/products/mb/socket754/k8s-mx/overview.htm# tells me, your board has Integrated 10/100 LAN in a highly integrated single-chip Fast Ethernet controller. Also it is the most cost effective in K8 solution which implies 'no advanced interfaces'...

Also, the southbridge is a SiS 965L, which according to http://www.sis.com/products/sis965l.htm just integrates a IEEE 802.3 and IEEE 802.3x compliant MAC with external LAN physical layer chip supporting full duplex 10 Base-T, 100 Base-T Ethernet. Have you tried the sis900 driver? What does lspci say?

Yeah, I tried the sis900 driv

on
March 11, 2005 - 10:32am

Yeah, I tried the sis900 driver off the bat, since the hd i'm using was previously in a box with that particular nic. modprobe says 'init_module(): No such device' or something like that. lspci says: Ethernet controller: ... [SiS]: Unknown device 0190.

In my Asus manual it says it includes the sis191/sis190 device driver for it on the cd (for windows, of course :\) and also mentions enabling /disabling the 'sis 190 lan device' from bios. If you really want you can download the manual to verify those facts (http://www.asus.com/pub/ASUS/mb/sock754/k8s-mx/e1884_k8s-mx.pdf, page ix (or 9 according to xpdf) and others).

I'm not much of a hardware guru or anything, so i'm not exactly sure what it implies, but i know it flat out says it uses sis 190 Gbit ethernet repeatedly :P.

interestingly...

SiS don't know their own chip:

http://www.sis.com/function/search.php?keyword=sis190&imageField.x=0&ima...

http://www.sis.com/products/product_000015.htm

And on the layout picture on page 16 there are only the chips we know about. The "Realtek RTL8201 PHY" chip is explicitely listed in sis900.c in the linux sources. Maybe ASUS for some reason reprograms the pci ids? Or do you have an ethernet card plugged into a slot?

I have the same problem with

on
March 15, 2005 - 11:20am

I have the same problem with the same motherboard. Upon loading sis900.ko, I find a sis900 status message in dmesg, but it fails to make the device available as eth[x]. I have to use a different NIC to connect to the outside world.

silently changed?

on
March 15, 2005 - 11:33am

Can we assume ASUS silently uses new incompatible chipset revisions in newer boards and hides this fact by shipping an exchanged windows driver and updating the minimal parts of their documentation to not be fraudulent? Nothing except the real hardware behavior indicates the interface to be sis190, at least according to the chip manufacturer who ought to know (or updated the chips but wants to hold a press event before documenting it on the web site).

Anyway, that doesn't solve the driver problems...

If you grab a new pci.ids file from pciids.sf.net then `lcpci' should show the right details. Alternately use `lspci -n' and then look up the PCI ID manually.

sis190: my findings

on
March 14, 2005 - 8:48am

Hi,

My situation is almost exactly the same as sinthetek's.

The source for this driver *was* present in the kernel, but was removed by Jeff Garzik in April 2004 (http://gkernel.bkbits.net:8080/net-drivers-2.6/cset@1.1371.1.405), since:
"The driver was copied from the very-buggy r8169 (pre-Francois),
and is for hardware that isn't even out of the lab yet."

The last kernel in which the driver was present is 2.6.5, IIRC (which is why I am puzzled by sinthetek's reference to 2.6.10 above). I obtained sis190.c from that kernel and tried it, both as a module and also compiled into the kernel, but it didn't work. When I loaded it as a module, it cribbed that "module falsely claims to have parameter MEDIA" or words to that effect. When I compiled it into the kernel(Fedora core 2, 2.6.9), the device was detected, but it was inactive, and I couldn't get it working.

I can send you the source if you want it. Or you can get it from the link above, but you might have to do some editing.

Note that I tried to use the driver source (from 2.6.5) with kernel 2.6.9. Perhaps that was the cause of the problem - I haven't tried downgrading to that kernel.

IDE controller on the same motherboard

March 20, 2005 - 4:28am

prasanthvr: yeah, i think i was mistaken pertaining to the 2.6.10 thing... i guess i misinterpreted one of my search results or something. (i tried downgrading to 2.6.10 and found no mention of the sis190 driver in it).

On a different note, are any of you guys witha k8s-mx using an eide drive? I'm using one I had in my old box, maybe one day i can afford a sata drive :P. but in the mean time...i can't seem to get dma enabled for some reason. It uses an sis5513 chipset and i've enabled all appropriate options in the kernel as far as i can tell:

You can add "handled = 1;" in SiS190_interrupt to fix the problem.

static irqreturn_t
SiS190_interrupt(int irq, void *dev_instance, struct pt_regs *regs)
{
struct net_device *dev = (struct net_device *) dev_instance;
struct sis190_private *tp = dev->priv;
int boguscnt = max_interrupt_work;
void *ioaddr = tp->mmio_addr;
unsigned long status = 0;
int handled = 0;

do {
status = SiS_R32(IntrStatus);

/* h/w no longer present (hotplug?) or major error, bail */

SiS_W32(IntrStatus, status);

if ((status & (TxQ0Int | RxQInt)) == 0)
break;

// Steve Tsai
handled = 1;

Did you ever get sis 190 working? It appears that you must recompile your kernel with a patch for your kernel (mine is 2.615)
simple instructions are at http://www.howtoforge.com/kernel_compilation_ubuntu
kernels and patches at http://www.vi.kernel.org/pub/linux/kernel/v2.6/. there have been numerous patches that include the patch for the sis 190 drivers I'm using *.15.7 because some patches needed patches themselves so I assume if I get the latest I'll be okay. I'm concerned about losing data. I don't know what happens when you recompile a kernel.

Built-in kernel driver

on
October 29, 2005 - 7:25pm

I recently bought a mobo ASUS K8S-MX with an on-board SIS 190 LAN card, and had to wait until the release of the 2.6.14 kernel to get the card up. In this version there is a built-in driver for that card, that at a first sight seems to work.

Now I have another problem: the card works fine since I tested it on window$s, but on linux, when I try to download files, the card doesn't behave well (the download is unstable, sometimes it stops downloading and continues a few seconds later, sometimes the download is interrupted,etc).

I see this behaviour even when I try to update my Debian with apt. I've tried to download many files from many sources (java virtual machine, netbeans ide, kernel sources from kernel.org, updates from debian mirrors, etc), and the problem presents on every single try (driver problem?)

So if there is somebody that has tested the built-in driver, please post a comment on this issues.

Thanx

Re: Built-in kernel driver

It seems that the unstabilities were due to hardware problems (a very old 10 Mbps mal-functioning hub). Thanks to Francois Romieu (driver mantainer) for some useful comments.

I just installed the latest FC4 kernel (2.6.14-1.1633_FC4) and it does recognize the ethernet card now, but my experience is much like yours in your first message: works fine in Windows but is very unstable in Linux. It seems as if it can only send/receive small bits of information, anything slightly bigger and the connection just dies (nothing appears in the logs).

Anything that Francois Romieu told you that might help me?

Gave up

on
November 2, 2005 - 2:02pm

Okay, I´ve given up on this motherboard (ASRock 939S56), it´s quite new and support for both Linux and "the other OS" is still in its infancy. On both OSes I experienced problems with lock-ups, mouse/keyboard suddenly not working anymore, CD-Rom which did not work with Linux etc etc.

So I just installed a Gigabit motherboard and everything has been working perfectly (great to see Linux immediately booting and working while Windows needed practically a complete re-install).

I thought I would just Windows until I got the wrinkels ironed out of the Linux install but when I noticed Windows had a bunch of problems as well I just gave up.

Well that´s what you get for not checking the Linux compatibility for the ASRock MB first.

AsRock Board works fine for me, but only after installing
2 identical RAM modules (dual channel). With only one 256MB
RAM (Kingston VR) it even refused to boot. Haven't checked
if Kingston RAM is faulty, simply bought 2 GSkill 128MB RAMs.

Now everything works fine, except I'm using Debian stable on
this thing (kernel 2.6.8) and there is no support for sis190.

I worked around this by buying an PCI card with RealTek 8139 chip
(costs: EUR 6,xx).

Reception error in Gentoo AMD64

I'm having similar problems with the SiS190. My motherboard is an Asus K8S-MX, and I'm currently running Gentoo amd64 with kernel 2.6.17-gentoo-r4 (which I configured by hand), although the behaviour was the same under 2.6.16-gentoo-r11. The device shows up as "00:04.0 Ethernet controller: Silicon Integrated Systems [SiS] 190 Gigabit Ethernet Adapter" in lspci.

The network seems to be okay for ordinary web browsing, as I'm on a home ADSL connection and the speed can't get too high. However, there are serious problems when using the card to access the local network (100Mbs via a fast ethernet switch). When I try accessing some larger pages on an internal webserver, or transfer files of any significant size via sftp or scp, I start getting RX errors and the operation hangs. It's even happened while just trying to ls the contents of some directories on another computer via ssh. I've noticed that the number of RX errors is always the same as the number of the RX frame, although I have no idea what that means.

I'd love to get to the bottom of what the problem is. This thread is the only place I've found any mention of something similar. It's almost certainly not a hardware problem, as I'm running a dual boot with Windows and the network is just fine there.

I called the manufacturer (foxconn) and I was instructed to install the SIS191 driver, but the only instructions were for kernel recompile. If I knew how to do that I wouldn't be using Ubuntu. How can SIS191 be installed by a newbie? I am my wits end I bought this board because I couldn't install Ubuntu on my HP Pavillion board. Now its installed but its useless because it can't connect to the internet.

If it is there then why didn't it install. Why are people installing programs such as ubuntu and their ethernet interface is not recognized. Obviously it's not there.

Have you managed to get this working? I had a similar problem which I fixed in sis190.c.
