[ANNOUNCE] libhwremote 0.1
by Carl-Daniel Hailfinger 11 Mar '12

11 Mar '12

I'm glad to announce libhwremote 0.1, a library which forwards hardware accesses over a serial line to a machine running SerialICE. No QEMU needed! All you have to do to run lspci/superiotool/... against a remote SerialICE target is to compile those tools against libhwremote, and then just run them like you would run them natively. libhwremote is an early prototype. Due to that it has quite a few quirks: - Each run of a libhwremote enabled application requires the application to be started before SerialICE prints its banner, i.e. start the application, then hit reset on the SerialICE target. The reason is the init code which expects "newline,serialice_banner,newline" to do anything useful. If that banner is not there, the results are undefined. - The error handling is mostly working but not really nice. - /dev/ttyUSB0 is hardcoded for serial line access, you may want to change that. - MMIO functions are totally untested, I didn't find any code which needed it (except for flashrom, but probing for flash chips might interfere with SerialICE functionality if SerialICE runs from ROM). - The pciutils patch is totally untested, but I expect it to work. A big THANK YOU goes to Idwer Vollering who tested a dozen iterations of this code until I had figured out the very surprising and unique properties of the SerialICE protocol. Another big THANK YOU goes to Ron Minnich who sent a mail titled "[SerialICE] an idea" which motivated me to start this little project: http://serialice.com/pipermail/serialice/2009-November/000043.html This code sat unfinished on my disk since December 2009, and it's about time I finished it enough to be usable. Notes:: - superiotool support is tested and stable - pciutils (lspci/setpci/...) support is untested, but should work. Please fetch latest superiotool from the coreboot git tree and latest pciutils from the pciutils git tree to apply the patches. libhwremote is available at: http://ra.openbios.org/~carldani/libhwremote-0.1.tar.gz superiotool patch is available at: http://ra.openbios.org/~carldani/superiotool_hwremote.diff pciutils patch is available at: http://ra.openbios.org/~carldani/pciutils_hwremote.diff I plan to check this code into a source code repository really soon, but for now a tarball and separate patch downloads have to suffice.

Unfortunately, there are ~6 different ways of rebooting an x86 machine (not all of which are available on any given system), so it's possible that CentOS triggered the "wrong" one in seabios, which in turn tries to use a method not supported by qemu (or something like that). > Could you give me some pointers as to where to begin for GSoC or some > little hacks that I should attempt out ?

Only by reducing the kernel size - kernel images are usually already compressed, so there's not much we can do. Fortunately, when putting the kernel in flash, you usually know rather well what kind of hardware you're running it on - so you can reduce kernel/initrd to just the drivers required to access the disk, and go from there. I think current qemu versions are more tolerant with flash sizes - you probably can't go above 4MB, but that should be enough to contain an optimized kernel. Regards, Patrick

A bit of help needed
by Jaspal Dhillon 10 Mar '12

Hello , I am currently a 4th year student ( B.Tech in CSE + MS ) in IIIT-H<http://iiit.ac.in/>and chosen field of study for MS is Virtualization. I have been using kvm , qemu and the libvirt library primarily to experiment with cloud frameworks and migration until now. I was going through the coreboot.org and I am definitely interested in it. So wanted to ask couple of things. I have not read the source code yet but tried it out in this way : 1.Checked out latest version of coreboot on 32bit Fedora 15. make config with settings as : MainBoard Vendor : Emulation , Model : Qemu , ROM Size : 256KB , Payload : SeaBIOS make was successful . Since my laptop is a old one and does not have hardware virtualization support , I use a lab pc ( 64 bit Fedora 15 ) for some of my experiments. scp coreboot.rom root@Lab: ; ssh root@Lab 2.qemu-img create disk.img 2500M 3.mkfs.ext2 disk.img 4.mkdir foo ; mv coreboot.rom foo/ ; cd foo ; ln -s coreboot.rom bios.bin 5.Copy some of the other bios files needed by Qemu ( otherwise , Qemu throws a file not found error and exits ): cp -r qemu_path/pc-bios/{keymaps, kvmapic.bin,pxe-e1000.rom,vgabios-cirrus.bin} /root/foo/ 6.qemu-system-x86_64 -L foo/ -hda disk.img -vnc 0:0 -m 512 -serial stdio -cdrom ~/CentOS-5.5-i386-bin-DVD.iso Installation of CentOS ( Minimum installation ) was successful and at the end , it asked me to reboot. When I clicked on reboot option , coreboot got stuck in an infinite loop and I was getting this (in a loop) on the stdio : Changing serial settings was 0/0 now 3/0 In resume (status=0) In 32bit resume Attempting a hard reboot I killed the process and started my vm again without the -cdrom option and it booted up fine. I am not sure if this is a bug or if I am doing something wrong. Can you shed light on it ? I have pasted the serial output at the end of email. ( There are some other 'file not found' errors but qemu + coreboot worked fine without them ). I am absolutely new to coreboot and used it for the first time yesterday but I love and admire it's goal , to replace the proprietary BIOS. Always thought , where's the code of BIOS ? Could you give me some pointers as to where to begin for GSoC or some little hacks that I should attempt out ? I am trying different payloads in the meantime. The initrd and vmlinuz of the CentOS I just installed have sizes of 3.2MB and 1.8MB respectively. If I want to use them ( a kernel payload ) , how should I ? I read about mkelfImage command and also tried it out but the resultant size of linux.elf is ~5MB which exceeds the size of ROM chip , declared in Qemu. Can I use a kernel payload ( any other ) without hacking Qemu ? ( I think not but want to know , if yes , how ) . Thanks , Jaspal PS : Sorry for the duplicate mail.

Patch merged into coreboot/master: 2fd6df0 If the memory mapped UART isn't present, leave it out of the cb tables.
by gerrit＠coreboot.org 10 Mar '12

10 Mar '12

the following patch was just integrated into master: commit 2fd6df0f261f0f9d587de15cb9e5861c3ff6811a Author: Gabe Black <gabeblack(a)google.com> Date: Wed Oct 5 01:57:03 2011 -0700 If the memory mapped UART isn't present, leave it out of the cb tables. This way u-boot won't try to use a UART that isn't plugged in.
