K-TEK-M275TP-FN-BL-ML USB keyboard support
by Аладышев Константин 28 Apr '18

28 Apr '18

Hello! I'm having problems with K-TEK-M275TP-FN-BL-ML keyboard (http://www.key-tek.cn/Productview.asp?id=777). It is USB device with keyboard and touchpad combined. It works in OS correctly, but doesn't work in SeaBIOS. I've tried to debug this issue and found that "usb_kbd_setup" function fails on "(epdesc->wMaxPacketSize != 8)" check, cause "epdesc->wMaxPacketSize" is actually 32. I've modified this "if" statement to pass 32 value also and now function completes successfully. But it didn't help to solve my issue. There are no interrupts from keyboard, "ehci_poll_intr" always returns -1 on check: if (token & QTD_STS_ACTIVE) { // No intrs found. return -1; } I don't know what to do now. What should I check next? Does SeaBIOS support USB keyboard+touchpad devices at all?

[PATCH 0/4] RFC: add CRB TPM device
by marcandre.lureau＠redhat.com 12 Feb '18

12 Feb '18

From: Marc-André Lureau <marcandre.lureau(a)redhat.com> Hi, The following series implements a limited TPM CRB driver. The TIS device with a TPM 2.0 seems to be ignored by Windows 10, so I implemented a simple CRB device that I will send shortly on the qemu-devel. With the CRB device, Windows 10 correctly recognized and exchange with a TPM 2.0. As long as the device isn't in qemu, I suppose this series should remain RFC. Feedback welcome!

Loading Option ROM for SATA Controller Card
by Adam Novak 26 Nov '17

26 Nov '17

I've installed a SI-PEX40064 SATA controller card <http://www.sybausa.com/index.php?route=product/product&product_id=156> in my system that I am trying to use with PCI passthrough via Xen, in order to give a guest VM its own real SATA controller so as to not have to deal with virtual disks. Moreover, I want to boot off of a disk attached to the card. The card implements (or pretends to implement) AHCI, so SeaBIOS starts up and can see the attached disk. But SeaBIOS gets a timeout communicating with the disk: |eff9d000| WARNING - Timeout at ahci_port_setup:469! |eff9d000| AHCI/2: device not ready (tf 0x58) The card has a PCI Option ROM, and I think the Option ROM needs to be loaded for the card to work and/or be bootable. But SeaBIOS refuses to load the Option ROM. (My real physical system with Asus EFI firmware and CSM enabled does load the Option ROM for the card when it is installed.) I dug into the code, and it looks like it's the same issue as is mentioned here: https://mail.coreboot.org/pipermail/seabios/2017-June/011425.html Basically, a device is not checked for an option ROM (or an fw_fcg/CBFS-based Option ROM file), and its option ROM is not loaded, if pci->have_driver is set for the device. That field gets set for anything that apparently implements AHCI, so the Option ROMs for AHCI controllers are skipped, even if they are useful. Removing that check causes the option ROM for my card to be loaded, and allows the bootloader stored on the disk attached to the card to start up. I've attached a patch that implements this change, and adds a few more debug messages to explain what is going on. I haven't observed any problems with my patched SeaBIOS under Xen, but I'm not sure why the check was there in the first place (as it wasn't commented), so I can't speak to the repercussions of disabling it on everyone else's machines.

Fw: Re: Re: Fw: Can VTPM2 support WINDOWS
by jwang＠whu.edu.cn 23 Nov '17

Hi，Berger， Thanks. But as I know CRB interface should be for mobile platform. We just want to support Windows Server 2012. Currently,the Windows Server 2012 can find physical TPM2 device. However, for vTPM, the windows server 2012 virtual machine just can find a virtual TPM 1.2 device and can not find vTPM 2.0 device. We have tried linux such as ubuntu and the ubuntu virtual machine can find vTPM 2.0 device in seabios 1.10 and our modified qemu-kvm-ev-2.6. This problem has been bothering us for a month. Could you give us some help?

So I want to know if the current seabios can support the windows guest OS when the tpm driver can not be modified. The host OS we used is CentOS 7.3 and the seabios version is 1.10.2. The hypervisor is KVM+QEMU. The windows version is windows server 2012 that can automatically support physical TPM2 chip. I only ever tried with Windows 10 and that requires a CRB interface (rather than TIS ) for a TPM2, which we will only get with the next version of QEMU. I would assume that this is also the case with windows server 2012. Stefan Looking forward to reply as soon as possible.

Hi,all, We want VTPM2 to support windows virtual machines. So I want to know if the current seabios can support the windows guest OS when the tpm driver can not be modified. The host OS we used is CentOS 7.3 and the seabios version is 1.10.2. The hypervisor is KVM+QEMU. The windows version is windows server 2012 that can automatically support physical TPM2 chip. Looking forward to reply as soon as possible.

Re: [SeaBIOS] [SLOF] [PATCH v3 00/17] Add vTPM support to SLOF
