K-TEK-M275TP-FN-BL-ML USB keyboard support
by Аладышев Константин
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 v1 0/3] tpm: Support 2.0 TPM devices connected to a TIS host
by Stephen Douthit
Changes from v0 -> v1
Patch 1/3
*Rename sts to value
Patch 2/3
*No Change
Patch 3/3
*No longer sending command to the TPM. Instead check the
InterfaceVersion field in the TPM_INTF_CAPABILITY register if necessary.
*Removed "Tested-by:" since I wasn't able to find 1.2 hardware for
regression test.
Stephen Douthit (3):
tpm: Refactor duplicated wait code in tis_wait_sts() & crb_wait_reg()
tpm: Wait for interface startup when probing
tpm: Handle unimplemented TIS_REG_IFACE_ID in tis_get_tpm_version()

[PATCH 0/3] Support TPM2.0 devices on TIS host
by Stephen Douthit
Hello all,
I ran into an issue getting a Infineon SLB9670 2.0 TPM running on an
Intel Denverton platform, and traced the problem to what seems to be
incorrect behavior of tis_get_tpm_version(). That function is returning
the version of the interface, and it seems the device version is what is
needed. The version check implemented here is based on the tpm2_probe()
function in the Linux tpm_tis driver.
This patch set applies on top of Marc-André and Stefan's "Add CRB TPM
device" patch series currently under review
I've tested this on real hardware with a SLB9670 hanging off of an
Intel C3758, but have not regression tested with TPM 1.2 devices.
Regards,
Steve

reboot fails with QEMU "isapc" machine type
by Daniel P. Berrangé
I was experimenting with old MS-DOS 6.22 under QEMU with the 'isapc' machine
type, and found it is not able to reboot the guest. Bisecting QEMU blamed
the QEMU change that rebased from "rel-1.9.3", to "rel-1.10.0". Further
bisecting SeaBIOS blames this change:
commit b837e68d5a6c1a5945513f1995875445a1594c8a (refs/bisect/bad)
Author: Kevin O'Connor <kevin(a)koconnor.net>

resume: Make KVM soft reboot loop detection more flexible
Move the check for soft reboot loops from resume.c to shadow.c and
directly check for the case where the copy of the BIOS in flash
appears to be a memory alias instead. This prevents a hang if an
external reboot request occurs during the BIOS memcpy.
Signed-off-by: Kevin O'Connor <kevin(a)koconnor.net>
I was testing as follows:
$ qemu-system-x86_64 -machine isapc -monitor stdio demo.img
where 'demo.img' is a disk image with MS-DOS installed (FreeDOS shows the
same problem too. Not checked any other OS).
Once C:\ command prompt is showing I enter
(qemu) sendkey ctrl-alt-delete
in the QEMU monitor console. Nothing visible will happen - the cursor will
stay flashing, but it no longer responds to input. Prior to this SeaBIOS
commit it will correctly reboot.
Interesting side note is that this only happens with QEMUs 'isapc' machine
type. The 'pc' machine type is still rebooting fine.
If I enable the isa-debugcon device in QEMU I see this when the 'isapc'
machine tries to reboot:
In resume (status=0)
In 32bit resume
Attempting a hard reboot
Unable to hard-reboot machine - attempting shutdown.
Regards,
Daniel

[PATCH v2 0/4] Add CRB TPM device
by Stefan Berger
The following series implements a 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 has now been integrated into QEMU. With the CRB device,
Windows 10 correctly recognizes and exchanges packets with a TPM 2.0.

The default seabios configuration is to build for qemu and not
coreboot. So, by default it would not include that code and would not
raise a compile time error. If you configured seabios to build for
coreboot and it didn't raise a compile time error then that seems like
a build defect.
