Hi,

attached the patch to add basic support for the mainboard in a so called IGEL-316 graphical terminal. I'm not sure who the original manufacturer of this mainboard is. It is labeled with "WINNET100 VER: 1.1 (30-3130000-110)"

Comments are welcome.

Great, thanks! Comments below, but please resend with a proper sign-off, otherwise we cannot commit the code: http://linuxbios.org/Development_Guidelines#Sign-off_Procedure

That, and please add the common license header to all source files: http://linuxbios.org/Development_Guidelines#Common_License_Header

(At least the following ones:)

- src/mainboard/igel/igel-316/auto.c - src/mainboard/igel/igel-316/chip.h - targets/igel/igel-316/Config.lb - src/mainboard/igel/igel-316/irq_tables.c - src/mainboard/igel/igel-316/mainboard.c - src/mainboard/igel/igel-316/raminit.h - src/mainboard/igel/igel-316/sdram_timing.h

What's the status of this code? Does it boot a payload correctly? Does it fully boot a Linux kernel? Which hardware works, which doesn't when booted with LinuxBIOS?

Is the above correct for the Winnet? What does 'lspnp -v' report when booted from the proprietary BIOS?

Also, can you please send some more system information (lspci -nn, /proc/cpuinfo etc. etc.) so it gets recorded in the list archives for other people who'll search for it later...

A full bootlog (LinuxBIOS + Linux, with maximum verbosity) would be nice, too.

Shouldn't we use igel_316 instead of igel-316 as directory name? All other mainboards do that AFAICS.

My guess is that this is an ASI/BCom board (but I don't have evidence), so it should go into targets/asi/xxxx, too?

Are you sure? Mine has a BIOS chip and a DoC. While the BIOS usually boots a kernel from the DoC, if you attach an IDE disk (with external power, as the thin client doesn't provide it), it will boot a Linux from the disk just fine.

Status is "tested on my boards" (I'm currenlty using 5 IGEL-316 at home). It works with etherboot and FILO. And boots my 2.6.21 kernel with Video and without (one IGEL is my file server, the others are small X terminals, connected to my main workstation).

Are you sure? Mine has a BIOS chip and a DoC. While the BIOS usually boots a kernel from the DoC, if you attach an IDE disk (with external power, as the thin client doesn't provide it), it will boot a Linux from the disk just fine.

Yes I'm sure. At system start I only see "booting...". No way found to stop it.

On my system there's no need to enter the BIOS. Just attach an IDE disk (and power for it), and the BIOS will automatically boot from that (instead of the DoC).

FWIW, I can enter the original BIOS by pressing ESC while the IGEL logo is displayed on the screen.

What's the status of this code? Does it boot a payload correctly? Does it fully boot a Linux kernel? Which hardware works, which doesn't when booted with LinuxBIOS?

Status is "tested on my boards" (I'm currenlty using 5 IGEL-316 at home). It works with etherboot and FILO. And boots my 2.6.21 kernel with Video and without (one IGEL is my file server, the others are small X terminals, connected to my main workstation).

So X11 works? Sound? Ethernet? USB? Booting from USB? All the other hardware such as keyboard, mouse, parallel port etc. etc?

Ok, here we go:

- X11 works fine. But not with the official geode driver from Xorg. This driver relies also on the SMM, so it fails on my LinuxBIOSv2 based system - With my own Xorg driver implementation it works fine! - Sound: I can play mp3 with "madplay". But only on a system with no other load. My driver must poll the SMI registers to know when the sound DMA finishes a data block. I need to play with priorities and maybe RT Preempt to ensure my polling routine will always get the CPU when there is the need. Otherwise system hangs. The sound DMA seems to be a fragile beast. - Ethernet: My onboard RTL8139C works since month. All systems are running "in production". My Geode based fileserver 24hours@365days... - Booting from USB? Not tried yet. Only etherboot and FILO (harddisk). But connecting memory sticks and MP3 players works fine (very important for my children!). - Keyboard: PS/2 and USB based keyboards are working fine - Mouse: PS/2 and USB based mice are working fine - LPT: Don't know. Never tried.

Is the above correct for the Winnet? What does 'lspnp -v' report when booted from the proprietary BIOS?

As I stated. I copied it from the eaglelion/5bcm and modified it until it works on my hardware...

Same here. Is it mainboard-specific? Otherwise merge it into src/northbridge/amd/gx1/raminit.[ch]? Should it get its own file? If so, why?

Some parts are mainboard specific, some are SDRAM specific. Unless we can read back the SPD EEPROM, we must manually add the SDRAM data.

Yes, reading the SPD values is definately the correct thing to do. We should try to make that work...

Yes.

...

...
...
I'll try to dump the SPD information on my Winnet3 and report the results...

But it would be valid only for exact one SDRAM type! Not for all the others.

Ah yes, sure, the SDRAM info is specific. I meant that I'll check whether reading SPD values works at all on my board.

I think no one of this manufacturer has made his own development. They all redo National's reference schematic in various ways to ensure the standard BIOS will work (this is one advantage of closed source: You must be hardware compatible in any way to ensure it works...). Does someone has this reference schematic? This would help to improve our development.

Hi,

attached the patch to add basic support for the mainboard in a so called IGEL-316 graphical terminal. I'm not sure who the original manufacturer of this mainboard is. It is labeled with "WINNET100 VER: 1.1 (30-3130000-110)"

Please dont put raminit into the mainboard specific code. It belongs to the northbridge code instead. Please implement this generic.

But how? Without access to the SPD EEPROM content, I need some way to define board specific what kind of SDRAM is in use. And we need a way to consider some board/layout specific things (delay values, load and so on). To setup the SDRAM controller in a correct way we need all this info. And this info is not generic!

It seems to find a generic way to configure the SDRAM in a Geode bases system is nearly impossible. At last we need some information about

- the physical behaviour of the mainboard (line load, line length for delay calculation, max possible SDRAM clock, jitter and so on) - the type of connected SDRAM modules (soldered, SO-DIMM, DIMM -> line load/length!) - the type of the SDRAM devices (timing requirements)

Maybe we are able to detect the SPD EEPROM on *some* boards. But never on all boards. There are too many individual incarnations how you can connect the I2C lines to your CPU (thanks to popconserve for the reference schematics!). Mainboard's physical behaviour (I believe) you never can autodetect. So we might need a filestructure you can try to autodetect things, or to hardcode most or all of the required settings. And then call ram_init with this data. Any idea? The faked-SPD alone does not help.

Yes and no. Where ever you have some spare GPIOs you can connect an I2C bus. And it seems every manufacurer did so. Some connect it to the companion chip, some to the multiIO, various multiIOs are possible. How to deal with it?

...

raminit could call back some board specific routines to query for SDRAM params. And they handle it in a board specific way. Some ask the SPD EEPROM if they know how deal with the I2C, some other provide generic params, and some uses specific params as one know the SDRAM devices that are plugged in.
