LAB (LinuxBIOS-like thing for embedded ARM-based devices)
by Joshua Wise 04 Nov '03

04 Nov '03

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey all, Some of you may remember me as the LAB guy (Linux As Bootldr). Just wanted to let you all know that LAB is booting on the iPAQ h3900. It's currently 512kbytes, and I don't expect it to go over that, although I'm aiming for 256kbytes. Code is in handhelds.org CVS. Does anyone have any suggestions for fitting a kernel 2.6 in sub-256k? /joshua (Also, I've got me an ABIT KG7-RAID here. I've been sick and tired of the crap BIOS that comes with it. What information do I need to collect so I can start working on this board, and what hardware do you all think I should use?

device configuration
by Greg Watson 03 Nov '03

03 Nov '03

Hi, Can someone please provide some assistance on the new device configuration setup? For example, how do I configure the IDE controller on a Winbond chip? I used to do this through the enable routine in the chip_control structure but this is no longer used. I've tried using the enable_dev routine, but it never seems to get called. Do I need to do something with the 'pci' configuration statement? What is the purpose of these? I've tried defining 'pci 0:9.0 on' and 'pci 0:9.1 on' but it doesn't make any difference. Thanks, Greg

rom for epia m-10000
by Xavier Pegenaute 03 Nov '03

03 Nov '03

Hi, finally! I obtained the flash memories for epia m 10000, now i'm trying to put LinuxBios, but in all the tests that i made no one printed somethig throught serial line. I have no idea about the problem. I know that serial line work because if i put "console=tty0 console=ttyS0,115200" in lilo with the normal bios i can see the msgs of kernel. Any one have some binry image for an epia m-10000 ? or some other idea? Thanks. Xavi. PD: I bought them in www.progshop.com

RomCC
by Dave Ashley 03 Nov '03

03 Nov '03

These discussions on romcc running out of registers, optimizations, inline and all are surprising. Isn't the point of romcc to just get the system ram up right at the beginning? Then once that is done any compiler (gcc) can be used to write code. Because dram configuration is so complicated and interpreting the SPD data from the dram, people would rather code that in 'C' than in x86 asm, so that's the purpose of romcc? -Dave

So need one customerization Installation image to execute the sh to install conf file. Also the kernel in the installation image should support X server without VGA init.

If the user writes the FILO configuration file. It will be possible that FILO loads the configuration file from distribution CD and boot from the CD almost automatically, and the distribution installer creates the FILO configuration file on the hard disk, so the machine will boot from hard disk next time. (the default location of the config file can be saved in CMOS) So the LinuxBIOS pre-installed workstation will be possible. -- Takeshi

Sone, So if the user installed the Linux Distribution to HD in normal BIOS and after that he flash the ROM to LinuxBIOS with FIFO and the system call work without any problem.

FILO loads vmlinuz and ELF kernel from filesystem (like ext2) on the local IDE hard disk, CD-ROM, CompactFlash, or ROM. It's working well on my EPIA, and also reported to work with K8 based boards including Tyan's. See this for details: http://te.to/~ts1/filo/ My plan is to add support for configuration file, so the default kernel location and parameters will no longer be hard coded in the Flash, and Stephan told me maybe he can support this config file in the future releases of SuSE installation CDs. -- Takeshi

To confirm where you are running out of registers I would suggest commenting out the code in question to see if it compiles without it. Knowing that should help craft a solution. Depending on the nature of the problem and how we are running out of registers it might make sense to store a couple of values in a single variable. If you want to keep it from running forever before it gives up I suggest -fmax-allocation-passes=8 -fdebug-live-range-conflicts. The -fdebug-live-range-conflicts is not terribly interesting except it tells you how many passes romcc goes through before it gives up. The -fmax-allocation-passes=8 sets the limit on the number of register allocation passes romcc will use. The most I have seen it make and succeed in my regression tests is 6. And the default is 100.
