Current tip not booting from USB or SD cards

by Stefan Berger

Hello! The current git tip does not boot from USB or SD cards on an Acer C720. The issue seems to stem from: ab9d771ce14d5b8d38cde373d15a51b45efb99c6 is the first bad commit commit ab9d771ce14d5b8d38cde373d15a51b45efb99c6 Author: Kevin O'Connor <kevin(a)koconnor.net> Date: Sat Jun 14 12:48:35 2014 -0400 ehci: Update usb command timeouts to use usb_xfer_time() Signed-off-by: Kevin O'Connor <kevin(a)koconnor.net> :040000 040000 4fcdb230f8fcffc0d8256225eb3c3220bd2293d4 78b62cb78cc3537da5a2ce1f1417fb1e0a571ba1 M src Regards, Stefan

[PATCH v8 0/8] Add TPM support to SeaBIOS

by Stefan Berger

This is a repost of a series of patches providing TPM support to SeaBIOS. As an addition, this patch series now works on the Acer C720 Chromebook with limitations (S3 not getting invoked; no logging into TCPA table). The patch series cleanly applies to a checkout of tags/rel-1.7.5. The following set of patches add TPM and Trusted Computing support to SeaBIOS. In particular the patches add: - a TPM driver for the Qemu's TPM TIS emulation (not yet in Qemu git) - ACPI support for the TPM device (SSDT table) - ACPI support for measurement logging (TCPA table) - Support for initialzation of the TPM - Support for the TCG BIOS extensions (1ah handler [ah = 0xbb]) (used by trusted grub; http://trousers.sourceforge.net/grub.html) - Static Root of Trusted for Measurement (SRTM) support - Support for S3 resume (sends command to TPM upon resume) - TPM-specific menu for controlling aspects of the TPM All implementations necessarily follow specifications. When all patches are applied the following services are available - SSDT ACPI table for TPM support - initialization of the TPM upon VM start and S3 resume - Static root of trust for measurements (SRTM) that measures (some) data of SeaBIOS in TCPA ACPI table - 1ah interrupt handler offering APIs for measuring and sending commands to the TPM (trusted grub uses them) - User menu for controlling aspects of the state of the TPM Stefan Berger (8): Add an implementation of a TPM TIS driver Provide ACPI SSDT table for TPM device + S3 resume support Implementation of the TCG BIOS extensions Support for BIOS interrupt handler Add 'measurement' code to the BIOS Add a menu for TPM control Add a menu item for displaying TPM diagnostics Make the TPM menu work on a Chromebook (Acer C720) Makefile | 12 +- src/Kconfig | 15 + src/boot.c | 28 +- src/cdrom.c | 10 + src/clock.c | 12 + src/config.h | 1 + src/fw/acpi-tpm-ssdt.dsl | 24 + src/fw/acpi-tpm-ssdt.hex | 27 + src/fw/acpi.c | 41 + src/hw/tpm_drivers.c | 273 ++++++ src/hw/tpm_drivers.h | 91 ++ src/optionroms.c | 4 + src/post.c | 9 + src/resume.c | 2 + src/sha1.c | 145 +++ src/sha1.h | 8 + src/std/acpi.h | 20 + src/tcgbios.c | 2208 ++++++++++++++++++++++++++++++++++++++++++++++ src/tcgbios.h | 431 +++++++++ src/util.h | 32 + 20 files changed, 3388 insertions(+), 5 deletions(-) create mode 100644 src/fw/acpi-tpm-ssdt.dsl create mode 100644 src/fw/acpi-tpm-ssdt.hex create mode 100644 src/hw/tpm_drivers.c create mode 100644 src/hw/tpm_drivers.h create mode 100644 src/sha1.c create mode 100644 src/sha1.h create mode 100644 src/tcgbios.c create mode 100644 src/tcgbios.h -- 1.8.1.4

Coverity detected issues in SeaBIOS

Hello, We run Coverity on the Xen source code occasionally and it happens to include SeaBIOS. The following new warnings have appeared since I pulled in rel-1.7.5.

Coreboot/Seabios cold boot laptop keyboard does not work

by Inez G

I have setup Coreboot with Seabios to run on a Lenovo X131e laptop. It works fine, except for the non-responsive keyboard on cold boots. With a warm reboot (restart) I can use the laptop keyboard to press F10 and then specify the number for the operating system/drive I want to boot from. But with a cold boot (from a previously powered-off state), the laptop keyboard does not work until I get to the password prompt in linux. So, with a cold boot, Seabios just defaults to boot from the first device in the boot order. An external USB keyboard, however, works fine (for both cold and warm reboots) to enter F10 for the boot order and to select the OS/drive I want. I tried setting the boot-menu-wait and the ps2-keyboard-spinup options with times as high as 90 seconds (90,000 milli sec), but the laptop keyboard still did not work on a cold boot. After the 90 seconds, Seabios just selects the first device to boot from. Any suggestions? Thanks

How to load but not run Option ROMs?

by Paul Menzel

Dear SeaBIOS folks, in the thread *Help for Coreboot project* [1] on the coreboot mailing list, Denis Carikli wrote that to get graphics under Linux (not GRUB or SeaBIOS) with AMD/ATI graphics devices it is enough to place/load(?) the Video BIOS/VGA Option ROM at the right place and not run it. The same is needed for some Intel devices (Google Chromebooks) so the VBT, needed for setting up the panel, is found. Enabling that option in coreboot (currently only possible by changing `def_bool` to `y`) and disabling Option ROM handling in SeaBIOS did not work. I think SeaBIOS overwrote the region (`/proc/iomem`). Looking for configuration options in SeaBIOS, there is the Kconfig option `OPTIONROMS_DEPLOYED`, which only available for QEMU though. Also it uses placed/loaded Option ROMs and still runs them. I guess more Kconfig options have to be added to support my use case. Is that wanted or should I do as Denis wrote and patch the SeaBIOS locally? Thanks, Paul [1] http://www.coreboot.org/pipermail/coreboot/2014-July/078293.html [2] http://review.coreboot.org/5594

SeaBIOS TPM support on Chromebook Acer C720

by Stefan Berger

Hello! I added support from the TPM to SeaBIOS and have parts of the BIOS functionality successfully running on a Chromebook Acer C720 (as example hardware). Here are some findings on the Acer: The TPM is successfully detected but sending TPM_Startup(ST_Clear) to the TPM fails since either coreboot or some other firmware seems to already have initialized the TPM, which is fine, and also extended PCR 0 with at least one hash. Ideally there would be a TCPA ACPI table containing information about what was logged, since otherwise the state of the PCR seems not that useful. SeaBIOS's TPM extensions could then also use this TCPA table and add its own logs into it along with extending PCRs in the TPM. So, in this case the TPM SeaBIOS extensions don't log anything and adding additional ACPI tables to the existing coreboot tables seems 'impractical'. I was wondering if coreboot could add such a table if a TPM was found to be present? Regards, Stefan An older version of the SeaBIOS TPM patches can be found here (for now): http://www.seabios.org/pipermail/seabios/2011-August/002252.html

expecting string instruction after `rep' with latest SeaBIOS

by Ian Campbell

Building the seabios defconfig on a 64-bit Debian Wheezy system I'm seeing: Compiling (16bit) out/romlayout.o src/romlayout.S: Assembler messages: src/romlayout.S:285: Error: expecting string instruction after `rep' make: *** [out/romlayout.o] Error 1 That line is: // Acquire lock and take ownership of shared stack 1: rep nop I've also checked the preprocessed version and the nop isn't being disappeared or anything like that. This is with 083ee297ef88d "ohci: Update usb command timeouts to use usb_xfer_time()". I don't see it with the rel-1.7.5 tag. git bisect has fingered 0673b7870063a ""smp: Replace QEMU SMP init assembler code with C; run only in 32bit mode.", which makes sense since it made those additions to romlayout.S Other than a compiler bug I can't think what might be going on. Debian Wheezy has gcc 4.7.2 and binutils 2.22. Ian.
