The telematics/Car-PC's we've been designing also have CDMA/GPRS, CAM, WiFi and WiMax soon, USB2.0, 1394, 10/100 ethernet, Bluetooth and Cardbus. The telematics/Car-PC's allow the driver and passengers to have real time navigation, voice over IP, and high speed satellite connectivity to the internet while the vehicle is in motion. The driver can be following the on screen maps while the kids in the back seat can be watching a Mpeg movie or playing their Xbox or Playstation2 network games. The telematics/Car-PC's will also allow for full speed video teleconferencing and several other data services while the vehicle is cruising down the interstate or stuck in city traffic. -Bari

That does seem to have some merit. Where are you seeing the code run slowly? In particular I am wondering if this is an mtrr setup problem or something else you are avoiding.

Although, AMD64 would be over-kill for a Car-PC, LinuxBIOS-AMD64.pdf is probably the most up to date document on LinuxBIOS v2 (freebios2): http://www.openbios.org/LinuxBIOS-AMD64.pdf Sincerely, Ken Fuchs <kfuchs(a)winternet.com>

For S2885, I can not compile that under LOGLEVEL=8. And I have to comment out severl printk_debug in auto.c stage.

Can we > talk about this a bit first. Sure. First here are two examples. struct chip_opertations cpu_intel_socket_mPGA479M_control = { .name = "socket mPGA479M", }; Killing the name for cpu sockets allows us to kill the whole structure. struct chip_operations northbridge_intel_e7501_ops = { .name = "intel E7501 Northbridge", .enable_dev = enable_dev, }; First note that all we did with the names was to print them when we converted from the static to the dynamic tree. Nothing uses them anymore. Killing them is as simple as removing a structure member. And deleting a few lines of code. Bloatwise strings appear to be up towards the top of the list. This is really a continuation of killing the static device tree. If you like I will trade you gdb stubs for the currently useless debugging string names. ;) I just finished the code for that. The conversations of the last couple of days inspired me. :) Eric _______________________________________________ Linuxbios mailing list Linuxbios(a)clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios

VIA GPL Violation ?

hi guys was looking through via arena, and found this file : http://www.viaarena.com/guides/WinCE/fastboot%20v2.03.zip problem is, running strings */BIOS_*.BIN | grep inux gives 2 mentions of LinuxBios for each binary bios file, which makes the whole thing suspect... should via be hit with some GPL cluestick ?

Actually, just asking for the software (binary or source) is enough. They don't need to give it to _you_, if another third party has already acquired the binary or source (containing GPL code). Until the first public or _private_ release (binary or source) to a third party, modifications to GPL code can be kept private, but once any release of the code (binary or source) occurs, the full conditions of the GPL must be met.

The above are sufficient, but not necessary conditions for getting the modified source code under the GPL. Refer to the version of the GPL that LinuxBIOS is licensed under (Version 2, June 1991): http://www.gnu.org/licenses/gpl.html The code in question doesn't include source and the distributer of this code is not a non-profit, so the following clause applies: ------ # b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, ------ Such an offer is not included in the zip file and it must be, if any binary code in the zip file is generated from GPL licensed code, i.e. LinuxBIOS. Therefore, if any LinuxBIOS source or binary code is compiled/linked to generate binaries in the zip file in question, distribution of that zip file is a violation of the GPL. The next step is proving that GPL code (LinuxBIOS) is actually being incorporated. Without that proof, there is no GPL violation. Contacting the FSF for advise would be next best step. I don't see any point in discussing this potential GPL violation in a this public forum. However, continued generic discussion of the GPL and what it requires might be helpful.

Should be Ron. You should delete 855pm. Without (i) in i855pm, it will not be processed by config.g and ....

I am walking through the code converting the sizeram() functions and have run across a duplicate 855pm and the i855pm. The digitallogic/adl855pc is using the i855pm, so that appears to be the active one. Is there a reason we have two of these? If not can we just delete src/northbridge/intel/855pm?

LinuxBIOS debugging with an emulator
by Stephen.Kimball＠bench.com 28 Oct '04

28 Oct '04

Can someone tell me what the starting sequence is with LinuxBIOS? Reset jumps to crt0.s. crt0.s calls auto.E. auto.E is built using romcc, so source-level debugging is not possible. The statement locations can be found using the Lxxxx labels in linuxbios.map. Then hardwaremain is called. Hardwaremain is the first C function called. Crt0 and auto run out of FLASH. Hardwaremain is the first function called after LinuxBIOS is copied to RAM. Is this correct? Maybe this will help get the American Arium to work. Steve
