Re: [coreboot] Serial input / output with SeaBIOS 1.11.0
by Piotr Kubaj 25 Feb '18

25 Feb '18

I didn't get it working with SeaBIOS' SERCON, but I just moved on to SgaBIOS. It turns out it's actually better for me than SERCON, because it provides serial redirection to the point where kernel takes over, while SERCON only provides till bootloader starts. That feature of SgaBIOS makes it possible to use full disk encryption on FreeBSD (without unencrypted /boot), because the password prompt just before bootloader is about to start and currently it's impossible to redirect it to serial (bootloader can be redirected to serial, password prompt can not). With SgaBIOS, I can get a password prompt via serial, with SERCON it's not possible (at least I didn't find a way to do so). -- ________________________________________ / Toilet Toupée, n.: \ | | | Any shag carpet that causes the lid to | | become top-heavy, thus | | | | creating endless annoyance to male | | users. | | | \ -- Rich Hall, "Sniglets" / ---------------------------------------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || ||

"varverify32init.patch" in the attachments. To apply a patch please copy it to the coreboot directory, "cd" to coreboot, and - if seabios is already cloned (e.g. after building a coreboot once, followed by a "make clean" of course) run " patch -l -p1 < varverify32init.patch " Sorry, my previous message had a typo, the final results for testfunc() : (1) = OK, inside " cbfs_copyfile " (2) = OK, inside " coreboot_cbfs_init " (3) = ERR, inside " cbfs_run_payload " P.S.

Strange, I didn't apply any patches. I run D16 with stock coreboot 4.7 and OpenBMC. Could it be because I have different memory modules (4xKVR16R11D4/16)?

Mysterious "is VARVERIFY32INIT but used from" problem while trying to improve SeaBIOS
by Mike Banon 24 Feb '18

24 Feb '18

Friends, I need your help. While trying to improve SeaBIOS I got stuck at this very strange problem - which does not appear when you do a standalone build of SeaBIOS but it happens when you try building a coreboot together with SeaBIOS. Steps to reproduce: add this innocent looking function to the beginning of ./coreboot/payloads/external/SeaBIOS/seabios/src/fw/coreboot.c : int // doesn't matter if static or not testfunc(void) { int *c = malloc_tmp(sizeof(int)); // doesn't matter if _tmp or _tmphigh // free(c); // <--- commented out because doesn't affect the results return 0; } and try calling it from "cbfs_copyfile" function of the same file: static int cbfs_copyfile(struct romfile_s *file, void *dst, u32 maxlen) { ... void *temp = malloc_tmphigh(size); ... int ret = ulzma(dst, maxlen, temp, size); testfunc(); // <--- added ... } Then I get this problem while building a coreboot with together SeaBIOS : ... Compiling whole program out/code32seg.o Compiling whole program out/ccode16.o Compiling to assembler out/src/asm-offsets.s Generating offset file out/asm-offsets.h Compiling (16bit) out/romlayout.o Building ld scripts ERROR: .data.varinit.. is VARVERIFY32INIT but used from ['.text.runtime..', '.text.do_boot', '.text.malloc_tmp'] Makefile:162: recipe for target 'out/romlayout16.lds' failed make[2]: *** [out/romlayout16.lds] Error 1 Makefile:80: recipe for target 'build' failed make[1]: *** [build] Error 2 payloads/external/Makefile.inc:73: recipe for target 'payloads/external/SeaBIOS/seabios/out/bios.bin.elf' failed make: *** [payloads/external/SeaBIOS/seabios/out/bios.bin.elf] Error 2 However, if I try adding this function to the end of "coreboot_cbfs_init" function I don't get such an error: void coreboot_cbfs_init(void) { ... process_links_file(); testfunc(); // <--- works OK there } What is a difference between "cbfs_copyfile" and "coreboot_cbfs_init" that affects this behaviour? And why it is OK to call "malloc_" from inside the "cbfs_copyfile" function --- void *temp = malloc_tmphigh(size); --- but we couldn't call there our testfunc() which calls "malloc_" without running into this problem? Best regards, Mike Banon

Hello, Thank you for your reply. I reflashed (same build) the BMC module with a hotplug. Now it works like a charm, it got an ip, I can log through ssh, reboot, etc.. But now I have a new problem. If I try to boot from a halted system, with BMC module attached, the system fires up but Coreboot hangs: Unable to detect valid memory on any nodes. Halting! mct_d: fatalexit If I remove the BMC module the system boots fine. I have 4 Micron MT18JSF25672PDZ-1G4F1DD modules, located in CPU1 orange slots. I attach both console logs.
