Issues on initialization of PCI devices below root.
by lautriv
Hello,
i tried to get seabios up via payload from coreboot and failed on the
initialisation
of neccessary devices.
The board in Question is a Tyan S4882, consisting of K8 northbridge,
8131 southbridge, 8111 southbridge and Winbond w83627hf SuperIO.
You will see on the following pastebin-url that coreboot does a proper
init and can see all relevant devices.
I was also able to get VGA up via coreboot ( to reflect an accessible
device below root ) but not from within seabios. It probes only against
PCI 00:18.0 ... 00:18.3 which are on the northbridge itself.
I had a look on the sources and found it should see and init the whole
tree, also checked my sources against some patches i found on the net
and they are all applied or superseded.
the seabios was 1.7.1 and master from git
The relevant startup can be found here : http://pastebin.com/wZvRWm1Z
feel free to send me something to test out if there are unanswered
questions or contact me
in #coreboot on freenode's IRC. I'm not omnipresent but 8-12AM and
9-12PM CET should be fine ;)
Best regards, lautriv.

I am looking for a document on building & running
coreboot seabios to work with qemu-kvm. Do we
have such documents for newbies ?

[PATCH 00/11] q35: acpi bits
by Gerd Hoffmann
Hi,
This series adds the q35 acpi bits (as is, first two patches), then goes
cleanup stuff my subsequently moving reusable stuff to separate include
files and make both piix and q35 include them. Kept fine-gained
splitted for now so it is easy to reorder/squash stuff for merge.
Unsolved issues:
ISA devices. See patch #11 for an idea how to tackle this, I don't like
it that much though. /me is open for better ideas.
VGA. It's in slot 2 for piix and slot 1 for q35. So the current q35
dsdt is simply plain wrong as it declares the vga for slot 2. Is there
some way to deal with that in AML code? Note: That this isn't q35
specific issue. Recent qemu versions allow to place the vga in any
slot (try "qemu -vga none -device VGA,addr=0a.0").
Comments & Reviews are welcome.
cheers,
Gerd

[PATCH 0/4] misc fixes
by Gerd Hoffmann
Hi,
These patches are mostly cherry-picked from Jason's q35 patch series.
It carries some bugfixes and preparations for the q35 chipset support,
but not yet the q35 code itself. Should be ready for merge.
cheers,
Gerd

[PATCH] Collapse PCI device tables in pci_bios_init_devices().
by Kevin O'Connor
Use just one "struct pci_device_id" device table list in the
pci_bios_init_devices initialization code instead of three separate
tables. There isn't any compelling reason to use multiple tables.

We're executing a scsi script without enabling the lsi bus master bit.
There is also a bug in the lsi code:
1038 again:
1039 insn_processed++;
1040 insn = read_dword(s, s->dsp);
1041 if (!insn) {
1042 /* If we receive an empty opcode increment the DSP by 4 bytes
1043 instead of 8 and execute the next opcode at that location */
1044 s->dsp += 4;
1045 goto again;
Which causes the script interpreter to go into an infinite loop. This
should be moved to a bottom half or thread.

[PATCH] DSDT: Fix HPET _CRS Method
by Gabriel L. Somlo
Updated _CRS method for HPET, bringing it in line with the way it is
presented on recent hardware (e.g. Dell Latitude D630, MacPro5,1, etc);
Allows it to be detected and utilized from Mac OS X; Also tested OK on
Linux (F16 64-bit install DVD) and Windows (Win7 64-bit install DVD).
