Experiencing a qemu segfault and serialice accessibility problems
My problem is two-fold: 1) Running the patched qemu segfaults. $ sudo ./i386-softmmu/qemu -serialice /dev/ttyUSB0 -hda /dev/zero -L bios/ [sudo] password for idwer: SerialICE: Open connection to target hardware...

My problem is two-fold:
1) Running the patched qemu segfaults.

svn://serialice.com/serialice/trunk/qemu-0.11.0 It's already patched, and it has been updated more recently than the patch.
2) Right now, the serialice shell appears only once: after flashing serialice.rom and performing a soft reset from vendor bios to serialice.
SerialICE v1.5 (Aug 3 2010)
Sounds like SerialICE is depending on some initialization from the vendor BIOS. I guess an ugly way to test it would be to copy the working configuration bits from lspci and hard code them into SerialICE until you find what's wrong. Thanks, Myles

I think you also need to specify -M serialice.
Yes. The parameters changed from the patch to the tree version of qemu. I think we should retire the patch and let people generate their own from the tree, or find a way to keep it up to date automatically. Myles

Absolutely. The mechanism that lets you create your own patch is "make diff" on the top level. It is called for every release, but not in between. So whenever using the SVN version of SerialICE you also have to use the SVN version of the coreboot tree or you will most likely run into odd trouble. I had hoped that we could get rid of the "serialice" machine type, but except getting rid of another parameter it doesn't make a whole lot of sense. Stefan

Sorry to be dense. I missed that completely when I was coming up to speed with SerialICE.

I agree. Thanks, Myles

Yes, that worked very well, thanks.

I'll investigate that by setting up the superio only. If anyone wants to look at the serialice log produced by qemu, let me know. Myles

Like this ? E.g. this is what I found for ICH5's LPC_EN, offset address 0xe6: 00:1f.0 ISA bridge [0601]: Intel Corporation 82801EB/ER (ICH5/ICH5R) LPC Interface Bridge [8086:24d0] (rev 02): // snip e0: 00 00 00 80 00 00 08 14 33 22 11 00 00 00 67 45 pci_write_config16(PCI_ADDR(0, 0x1f, 0, 0xe6), 0x1408); Attached the mainboard code as well.
Thanks, Myles
