Hardware Datasheets?

Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.

Actually, QEMU supports the AMD PC-Net PCI chipset as well.. :wink:

Code: Select all

-M isapc -net nic,model=nek2_isa
-net nic,model=ne2k_pci
-net nic,model=rtl8139
-net nic,model=pcnet
As for the VIA Rhine II Fast Ethernet Adapter I have a surprise for ya pcmattman.. :wink:
http://www.viaarena.com/default.aspx?Pa ... bCatID=147

While source code is definitely no replacement for proper documentation, Maybe it'll be a good read over for implementing chipset support (It looks sophisticated..)

I'm not 100% on that NE DM-1001 card though, You might want to boot up BSD or Linux and see if it uses a common chipset or something (If it's detected..)

Good luck :)

Wow. Free code is good. Very good. :D

I've been able to get the maximum packet size of the 3Com cards by reading the registers. At least that means I understand the datasheet... Now to do something useful :D.

I would. I don't understand the hardware enough yet. I just want to write a driver for my OS that I can test without a reboot.

Wow, I didn't know they had an opensource driver. :]
good to see. I will put that on the list of items to port in the future.

They have source for some of their 3d graphics cards too.. Some other hardware as well, Kind of neat.. Documentation would be nice too..

Haha... I boot my OS on my testbed and it tells me I have an NE2K compatible card! I'm still coding a 3C90xC card driver, but I find it interesting that I can use an NE2K driver in my OS on real hardware...

What MOBO chipset you have? It could be if you have an integrated mobo it's Ne2k compatible? What makes me wonder though... what PCI IDs you actually detect?

Code: Select all

static struct pci_device_id ne2k_pci_tbl[] = {
        { 0x10ec, 0x8029, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_RealTek_RTL_8029 },
        { 0x1050, 0x0940, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Winbond_89C940 },
        { 0x11f6, 0x1401, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Compex_RL2000 },
        { 0x8e2e, 0x3000, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_KTI_ET32P2 },
        { 0x4a14, 0x5000, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_NetVin_NV5000SC },
        { 0x1106, 0x0926, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Via_86C926 },
        { 0x10bd, 0x0e34, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_SureCom_NE34 },
        { 0x1050, 0x5a5a, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Winbond_W89C940F },
        { 0x12c3, 0x0058, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Holtek_HT80232 },
        { 0x12c3, 0x5598, PCI_ANY_ID, PCI_ANY_ID, 0, 0, CH_Holtek_HT80229 },
        { 0, }
};
MODULE_DEVICE_TABLE(pci, ne2k_pci_tbl);
The above is from Linux ne2k-pci.c and the VIA in the list is integrated in chipset, so that's what you have?
The real problem with goto is not with the control transfer, but with environments. Properly tail-recursive closures get both right.

Well for a start it's not onboard, it's a PCI card.

And the card I'm talking about is a Novell card, pretty old. Still has a coaxial cable jack...

I think it didn't detect it earlier but now I've blown some cobwebs out (and added another 3 network cards to my testbed/server)...

        {"Via 86C926", ONLY_16BIT_IO},
From Linux again. Don't try to do 32-bit IO on that one. ;)

I just found out I have an RTL8029... Ironic, that's the only card my OS supports so far :D.

I have trouble with the 3Com implementation, can't even get an interrupt from the card :?

Did you test it out on there? I'm curious to see my code work on a real life machine.

I'm testing and modifying to make it work. ATM I use a sniffer on my main PC that can view the network data coming into it. All packets coming from my OS are malformed, so I'm working to try to figure out why. Basically in each packet every legit byte is followed by some other byte.

Have you tried packing the structures?, A could place to start would be packet_t and ethernet_t.

Are you saying that if you drop every other byte, you get the correct packet?

Maybe you've configured the card for 16-bit I/O and you are doing 8-bit I/O and it thinks you're doing 16-bit?

edit: oh ok, I checked your CVS and this doesn't seem to be the case. Your packet receive loop still looks a bit suspicious to me, I hope you know what your logic is supposed to do.... anyway... could be it doesn't support 8-bit?

I'll make sure that they do get packed...

I had a similar problem with UDP packets, the structure wasn't packed.
