[ANNOUNCE][CFT] kexec for v2.5.48 && kexec-tools-1.7
by ebiederm＠xmission.com 20 Nov '02

20 Nov '02

kexec is a set of systems call that allows you to load another kernel from the currently executing Linux kernel. The current implementation has only been tested, and had the kinks worked out on x86, but the generic code should work on any architecture. Could I get some feed back on where this work and where this breaks. With the maturation of kexec-tools to skip attempting bios calls, I expect a new the linux kernel to load for most people. Though I also expect some device drivers will not reinitialize after the reboot. The patch is archived at: http://www.xmission.com/~ebiederm/files/kexec/ And is currently kept in two pieces. The pure system call. http://www.xmission.com/~ebiederm/files/kexec/linux-2.5.48.x86kexec.diff And the set of hardware fixes known to help kexec. http://www.xmission.com/~ebiederm/files/kexec/linux-2.5.48.x86kexec-hwfixes… A compatible user space is at: http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.7.tar.gz This code boots either a static ELF executable or a bzImage. As of version 1.6 /sbin/kexec now works much more like /sbin/reboot. It is recommend you place /sbin/kexec -e in /etc/init.d/reboot just before the the call to /sbin/reboot. If you haven't called /sbin/kexec previously it will fail, and you can then call /sbin/reboot. Given the similiarity it is now the plan to merge in reboot via kexec into /sbin/reboot. One bug was fixed in the move to 2.5.48. Previously I had failed to clear PAE and PSE in the kernel. This caused reboot failures when CONFIG_HIGHMEM_64G was enabled, as the new kernel would fail when enabling paging, as these bits remained set. Is %cr4 present on all 386+ intel cpus, or do I need to conditionalize the code that accesses it? As of version 1.6 /sbin/kexec when presented with a bzImage by default avoids all BIOS calls and jumps directly to the kernels 32 bit entry point. The information it would usually get from the BIOS is instead collected from the current kernel. Accurately getting things like the BIOS memory map from the current kernel is a challenge, still needs to be addressed. Safe defaults have been provided for the cases I do not currently have good code to gather the information from the running kernel. In bug reports please include the serial console output of kexec kexec_test. kexec_test exercises most of the interesting code paths that are needed to load a kernel (mainly BIOS calls) with lots of debugging print statements, so hangs can easily be detected.

hi.. I install RH 8.0. I porting the linuxbios my k7sem board. I following method. linuxbios cvs downloading. cvs -d :pserver:anonymous@cvs.freebios.sourceforge.net:/cvsroot/freebios login cvs -z3 -d :pserver:anonymous@cvs.freebios.sourceforge.net:/cvsroot/freebios co freebios and then, download kernel linux-2.4.17 using ftp.(ftp.kernel.org) patch linux-2.4.17-sis.patch. kernel compile error mtd, video, sound when orginal config(cvs downloading) file using. my kernel config file is than. orignal config file is modified. ============================================ #

by albert 20 Nov '02

20 Nov '02

Hi everybody: i got an old asus p2b mainboard, and i wnat to make it linuxbios run-able. BUT, i can not get any response for ali about requesting chipset datasheet. the chipset on p2b is ali m1541 northbridge and m1543 southbridge the memory type is sdram. i want to make it boot from the flashrom, not yet linux, then if it boot, use harddisk instead of dom, due to i do not have DOM now!! could anybody help me, i will very very appreciate your help or there are some other methods i can do, please be kind to tell me. thanks advance

Can't get a rom image below 512k?
by Andrew Kohlsmith 20 Nov '02

20 Nov '02

I *think* I did this right. I'm getting a 64k linuxbios.rom and a 512k romimage file. I'm using 2.4.19 with the SIS patch (as per the SBC710 port doc). If I run the bios inside of bochs, I get a segfault (yes, bochs crashes!) after saying "prefetch: running in bogus memory". It does this for either the 64k rom image or the 512k one. Now my biggest concern is that the target board has a 256k flash device. I don't think I can fit 512k into 256k. :-) I'm using the digitallogic smartcore-p5 as a guide, as my target board is also a 430tx-based board. I've written an SMC FDC37n958fr super io intializer (based on the 37c67x) but otherwise they're pretty similar. My intention is to use the LinuxBIOS to either boot a real kernel using etherboot (I have to compile in PCMCIA then though) or to boot from a IDE-attached CompactFlash card. At this stage in the game my kernel is pared down just about as much as I can think to do it. no VT (serial console only), IDE, direct PCI and that's about it. Am I missing something? Regards, Andrew

Reversing the default value of CONFIG_COMPRESS from 1 to 0
by Ronald G. Minnich 20 Nov '02

20 Nov '02

Eric, how much heartburn is there if we set the default value of CONFIG_COMPRESS to 0? I've just hit another platform where it is trouble. At this point I believe there are only a small number of platforms for which it works well if set to 1. Do you have any issues if we have it default to 0, not 1, so it is only enabled on platforms it is "known good" on? thanks ron

booting elf from ROM
by Andrew Kohlsmith 20 Nov '02

20 Nov '02

I've managed to get all the way to jmp_to_elf_entry(), but I have run in to a snag in the assembly code which copies LinuxBIOS in to high memory and then attempts to continue execution up there. At line 130 of arch/i386/boot/boot.c the code attempts to jump to the next instruction in its new home. (the jmp EAX). When tracing through it in bochs, however, the EAX just points to the next instruction (in low memory, where it was executing before). The copy moves 0x12fab dwords (304kb?) from 0x04000 to 0x3fbb4154 (what on earth does this address represent?!) I seem to pass all the ELF header checks so I don't think my problem is anywhere in the etherboot code... Can someone maybe explain what jmp_to_elf_entry() is doing here? Regards, Andrew

Repeating problems with the 440bx, and 440gx, files attached
by Gregg C Levine 18 Nov '02

18 Nov '02

Hello again from Gregg C Levine Ron, I've tried your suggestion for the 440gx, it, looked like it did not work. I've attached a script file from that one. And for the 440bx, I have also attached a script file, and for it, the config file. I'm confused. Really confused. There are also some other errors during the build runs for the 440gx, if you want to see them, I'll make out a new script file for that one.

smartcore p3 is now solid
by Ronald G. Minnich 18 Nov '02

I had to do this: option CONFIG_COMPRESS=0 and all was well with the -current cvs tree. Nice little node, 750 Mhz PIII in PC/104 format. ron
