So next week, we can get the updated romcc? -----邮件原件----- 发件人: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] 发送时间: 2004年6月25日 17:41 收件人: YhLu 抄送: LinuxBIOS 主题: Re: [COMMIT] romcc 0.63 and some fixes...

I took some time and tracked the problem down. So far I have exposed 2 problems in romcc with your code. The first that was causing the core dump I have fixed. The second is a little more insidious. Basically when call/return instructions are introduced the control flow graph is no longer a graph. Because the structure changes depending on which path you take through the code. What happens currently is I treat it like a graph and get a conservative estimate on the control flow structure. So no incorrect transformations happen to the code. However there are a number of cases and your code was one where code that is correct does not appear to be. Because it appears that there are additional paths to a basic block, when there are not. The result is some legitimate cases will not compile. And likely that some optimization opportunities are lost. I suspect the lost optimization opportunities are responsible for the code size growth. Without calls and returns the dominance relationship between instructions is transitive. Instruction X dominates instruction Y if you must execute X before Y. With call/return pairs the dominance relationship is no longer quite transitive which is going to take some delicate manipulation to let romcc understand this without breaking it. I am going to spend a little more time looking at this and when I am done I am going to commit however many fixes/enhancements that I have. Eric

Eric, The printo_debug("this mainboard is only designed for 2 cpus\r\n"); causes the segment dump. Another problem. After only change print_debug in raminit.c, the final image size get bigger from 68663 to 70203.

I knew I had touched to much code for the new release to run without a hitch. Could you look at the core dump with gdb and give me a back trace? That should help even if I can't reproduce the problem on this end. Eric

Eric, I find the problem, need to call init_timer in p6 cpu fixup. It works well now. Some code should be moved to p6 or even p5. For example: apic_timper.c enable_mmx_sse.inc/disable_mmx_sse.inc regards YH -----邮件原件----- 发件人: YhLu 发送时间: 2004年6月25日 14:12 收件人: ebiederman(a)lnxi.com 抄送: ron minnich; Stefan Reinauer; LinuxBIOS 主题: Re: E7501 support in V2 Eric, I made some progress.

LVDS Support
by Michael Robinson 25 Jun '04

25 Jun '04

The VIA EPIA MII can be bought with an LVDS port on it and I was wondering the compatibility of this. Obviously its not supported under LinuxBIOS, but would it work under Linux? A guy told me that the LCD panel had to be supported by VIA's BIOS for it to work. Should Linux be able to setup something like this since LinuxBIOS leaves most of that stuff to Linux or does it have to be done by the BIOS (ie if Linux doesn't support LVDS)? Thanks, Michael Robinson mrobinson(a)fuzzymuzzle.com www.fuzzymuzzle.com

---The trend seems to be NOT to use DiskOnChip but rather a CF <> IDE adapter. Using FILO you can boot from the CF.--- So I'd flash FILO to the BIOS, then it would load the LinuxBIOS kernel image, and then the kernel image would do whatever you want LinuxBIOS to do, right? Or am I wrong... It says FILO loads a "boot image", whats the definition of a "boot image", is it just the kernel?

DiskOnChip Questions
by Michael Robinson 24 Jun '04

24 Jun '04

Hey guys, Please bear with me, I have some questions that are probably pretty basic but I can't find the answers anywhere. My first question is what does the DiskOnChip provide to the LinuxBIOs project that the standard flash chip can't? My second is that I'm going to be using the VIA EPIA MII motherboard which has a PLCC BIOS, as far as I can tell PLCC DiskOnChips aren't very readily available. Should I use a DIP to PLCC adapter; how did the other people who used this board do it? My final question is how do I pick the size of the DiskOnChip. What is LinuxBIOS's typical size requirement; do motherboards have a maximum BIOS size limitation? If BIOSs do have a maximum size limitation how do I figure it out, VIA says says the BIOS for my board is 2/4Mbit flash memory. Sorry if these seem very basic. Thanks, Michael Robinson mrobinson(a)fuzzymuzzle.com www.fuzzymuzzle.com

AMD64 emulators and other hardware based LinuxBIOS developing tools
by Ken Fuchs 24 Jun '04

24 Jun '04

I'm looking for a good/adequate tool for LinuxBIOS software integration/development for dual Opteron mainboards. The American Arium has recently added AMD64 support to their ECM-50 emulator. I've heard that the ECM-50 is $11K plus $4K for AMD64 module and $1.5K for support for a total of $16.5K. I've looked for other AMD64 emulators, but didn't find any. Are there cheaper AMD64 emulators? Something less than an in-circuit emulator may suffice. Maybe a bus analyzer that simply filters and records bus signals on the mainboard. The bus analyzed could be the processor bus, PCI bus, etc. I'm looking for at least a POST card. Maybe a POST card with extra features. I suppose even a processor adapter that allows processor pins to be probed with a logic analyzer might do as well. What hardware tools (emulators, bus analyzers, POST card, etc.) would you recommend for LinuxBIOS integration/development for dual Opteron mainboards? ------ Thank you Ron, YH and David for your comments concerning Nvidia CK8-04 support in LinuxBIOS! It was/is most appreciated! Sincerely, Ken Fuchs <kfuchs(a)winternet.com>

RE: Has anyone heard about EPIA MII FastBoot ROM Utility? < GPL Issue
by Stefan de Konink 24 Jun '04

24 Jun '04

Hello all, I'm trying to boot from the CF reader on the VIA Epia platform. After reading forums and mailinglist this could be possible by the FastBoot Utility. http://downloads.viaarena.com/WinCE/Apr04/fastboot%20v2.01.zip But I was a bit surpriced what I found in there... grep linux `find` and look at the 'loader*.obj'-files. Can somebody confirm this is _not_ distributed GPL code as a binary? Greetings, Stefan de Konink
