Fwd: [RFC 0/2] (Ongoing)Support multiple pci domains in pci_device

The pxb-pcie host bus is put into a separated domain, so are the devices under the pxb host bus. I think we should also initialize busses in other domains and probe those devices during bios initialization. But currently qemu only binds port 0xcf8 and 0xcfc to q35 host's conf_mem and data_mem, if we want to read the config space of pxb host, we should use another port. I use port range 0x1000 and 0x1004 for a temporary workaround because they seem to be 'free' now. Please correct me if I misunderstand it. P.S. Maybe you would want to ignore this patch set as there are a few bugs that I fix later, and I will soon send a v2 patch (v2 is not working either, but I think I find where the current problem is), soon after I fix my network proxy issue... Thanks Zihan

Re: [SeaBIOS] Problem with boot coreboot
by Mike Banon 09 Aug '18

09 Aug '18

Dear friend, have you tried this advice (given at your coreboot thread) : For the beginning, I recommend you to check if you could boot anything at all. In example, try making an Ubuntu LiveUSB from a spare USB flash drive, and using SeaBIOS try booting from it. If it is working, you could also try installing Ubuntu to a spare Hard Drive and also try booting for it. If all this is working (means the SeaBIOS booting capabilities are fully functional both for USB and SATA interfaces) - while booting FreeBSD still doesn't work - that means something is wrong either with FreeBSD installation or (more likely) its partition table or maybe GRUB2 is corrupted. Then you could try restoring GRUB2, by following these instructions for example - https://howtoubuntu.org/how-to-repair-restore-reinstall-grub-2-with-a-ubunt… If yes, it didn't help you?

[RFC 0/2] (Ongoing)Support multiple pci domains in pci_device
by Zihan Yang 08 Aug '18

08 Aug '18

NOTE: This patch set is still ongoing and does not fully function as its goal. But it involves some API changes, therefore I post them for comments before moving on to make sure I'm on the right path. The corresponding qemu part can be found at https://gitlab.com/WhoisZihan/qemu-pci-domain/tree/master/qemu I will submit it to qemu list later. Currently seabios assumes there is only one pci domain(0), and almost everything operates on pci domain 0 by default. This patch aims to add multiple pci domain support for pci_device, while reserve the original API for compatibility. Some part of it is dirty and hardcoded, as I plan to make it support 2 pci domains first as a working POC. Many works remain to do when BIOS checks and initializes PCI devices, because almost everywhere assumes 1 pci domain by default. It compiles and runs, but the guest will issue a "Bus 0001:00 not in PCI Namespace" warning, and it does not correctly recognize the bus under host bridges other than q35. If you have any clue about this error, please point me out, I will appreciate it.

Download URLs changed
by Paolo Bonzini 02 Aug '18

02 Aug '18

Hi, it looks like at some point the download URLs for SeaBIOS changed from https://code.coreboot.org/p/seabios/downloads/get/seabios-X.Y.Z.tar.gz to https://code.coreboot.org/p/seabios/downloads/seabios-X.Y.Z.tar.gz. Would it be possible to add a redirect or symlink from the old files, so as not to break places (such as distribution packages) that have the old URL in it? Thanks, Paolo

TPM 2.0 with SeaBIOS
by Piotr Kubaj 01 Aug '18

01 Aug '18

Hi, I use SeaBIOS 1.11.2 as payload with 4.8-835-g113f670baa on ASUS KGPE-D16 board. I also have ASUS TPM-L R2.0 module with Infineon SLB9665 chip. TPM is correctly detected by both Linux and FreeBSD. It's also detected by coreboot in debug console. But SeaBIOS doesn't cooperate with it - there's no TPM menu. In serial console, I get: TCGBIOS: Detected a TPM 1.2. rsdp=0x000f1930 rsdt=0xbf4b9030 table(41504354)=0xbf4bf460 TCGBIOS: Starting with TPM_Startup(ST_CLEAR) Return from tpm_simple_cmd(99, 1) = 1e TCGBIOS: TPM malfunctioning (line 874). Return from tpm_simple_cmd(73, 0) = 1e Note that SeaBIOS detects it as TPM 1.2, even though it's TPM 2.0. -- _________________________________________ / I find this corpse guilty of carrying a \ | concealed weapon and I fine it $40. | | | | -- Judge Roy Bean, finding a pistol and | | $40 on a man he'd | | | \ just shot. / ----------------------------------------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || ||

The list of runtime SeaBIOS settings is at: https://www.seabios.org/Runtime_config You could try playing with the etc/pci-optionrom-exec setting. See QEMU's -fw_cfg command line option. You'll need to pass in a binary integer zero or binary integer one to control that setting. -Kevin

Marvell 88SE9230 passthrough in KVM takes long time to boot
by Konrad Eisele 29 Jul '18

29 Jul '18

I'm passing through a Marvell 88SE9230 card to a KVM guest under Ubuntu 18.04. The card is a Sata controller with 4 ports. The option rom of the Marvell 88SE9230 card shows on a normal boot a bios screen. When pressing CTRL-m quick enough, you can interrupt the bootprocess and enter a menue wherer you can define raid arrays. When booting seabios inside KVM the bootprocess is very slow. There is a 1 min holdtime where the cpu is about 30%. The screen is black with only the seabios version string shown. I suspect that the passed-through Marvell 88SE9230 cards option roms causes this behaviour. Maybe the scanning for option rom cause the slow bootprocess? In the seabios boot case no bios menue is shown, after around 1 min the boot continues. Is it possible to disable the options rom processing? Is there some documentation about this (How can I configure it for Ubuntu) ? // Greetings Konrad
