[PATCH] Make CONFIG_ATA_DMA and CONFIG_ATA_PIO32 default on
by Paul Durrant 11 May '15

11 May '15

Currently running make defconfig will leave the above turned off which, at least for the Xen/QEMU use-case, means VMs will boot very slowly. There seems to have been some concern over non-QEMU use of ATA_DMA about five years ago, but I can find no particular concern over ATA_PIO32. Given the increased use of QEMU and Xen in that period it would seem like a good idea to default both of these on now. This patch does that.

[PATCH v9 0/6] Add TPM support to SeaBIOS
by Stefan Berger 08 May '15

08 May '15

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 a1ac8861. 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 - Support for initialzation of the TPM - init of TCPA logging table - 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) - Support for sending control messages from the OS to the BIOS and have the BIOS control certain life-cycle aspects of the TPM following those messages - 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) - With an extensions to QEMU's TPM SSDT: The root user in Linux (for example) can send the above mentioned control messages to the BIOS and have the BIOS act upon them - User menu for controlling aspects of the state of the TPM Stefan Berger (6): Add an implementation of a TPM TIS driver Implementation of the TCG BIOS extensions Support for BIOS interrupt handler Add 'measurement' code to the BIOS Support for TPM Physical Presence Interface Add a menu for TPM control Makefile | 5 +- src/Kconfig | 7 + src/boot.c | 28 +- src/cdrom.c | 11 + src/clock.c | 12 + src/config.h | 1 + src/hw/tpm_drivers.c | 291 +++++++ src/hw/tpm_drivers.h | 90 +++ src/optionroms.c | 4 + src/post.c | 12 + src/resume.c | 2 + src/sha1.c | 145 ++++ src/sha1.h | 8 + src/std/acpi.h | 20 + src/tcgbios.c | 2181 ++++++++++++++++++++++++++++++++++++++++++++++++++ src/tcgbios.h | 456 +++++++++++ src/util.h | 2 + src/x86.h | 7 + 18 files changed, 3277 insertions(+), 5 deletions(-) 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 -- 1.9.3

SeaBIOS can use VGA on PCIe cards - the problem appears to be that SeaBIOS isn't scanning all the PCI buses on the machine. Try setting extra-pci-roots as described previously. > Any ideas on SeaBIOS not booting from hard disks or USB storage devices? I suspect the problem with USB storage is really just a result of VGA not working and the behavior of third-party bootloaders when a vgabios isn't found. See my previous email. -Kevin

To support this, seabios needs the CBFS file 'etc/extra-pci-roots' to be set - see: http://www.coreboot.org/SeaBIOS#Other_Configuration_items Ideally, one would set this to the number of extra PCI roots (eg, 1 or 2), but it can also be set to 255 to force a scan of every PCI bus (which takes a little longer on each boot). > Here's a simple diagram showing roughly how devices are connected on the > board: http://ibin.co/20n6DtSrgZSv > > Here's the console output (SeaBIOS log level 8): > http://pastebin.com/jKu21dTV > > SeaBIOS also detects USB mass storage and hard disk drives, but can not > boot from them.

I don't see anything wrong in the log - those messages all appear normal. It's not uncommon for bootloaders to get confused when a vgabios isn't present, so I'd track that down first. If you can't get VGA working, consider installing sgabios as described at: http://www.coreboot.org/SeaBIOS#Adding_sgabios_support -Kevin

Sun Ultra 40 M2 - VGA Card Option Rom not detected
by Nick 07 May '15

07 May '15

Hi guys, I just got coreboot with SeaBIOS payload up and running on a previously unsupported system. The system is a Sun Ultra 40 M2 which is very similar to the NVIDIA l1_2pvv development board (which already has a coreboot port.) Coreboot detects the VGA card and outputs the text "found VGA at PCI: 43:00.0", however, SeaBIOS does not seem to be able to detect the VGA card and doesn't seem to enumerate that bus. It would appear that the option rom is not being ran. Here's a simple diagram showing roughly how devices are connected on the board: http://ibin.co/20n6DtSrgZSv Here's the console output (SeaBIOS log level 8): http://pastebin.com/jKu21dTV SeaBIOS also detects USB mass storage and hard disk drives, but can not boot from them. There's a HALT statement and a bunch of errors (also seen in the log file.) The boot device was a USB mass storage device with linux installed and boots successfully with the vendor bios. Thanks in advance! -Nick

SeaBIOS not fully working when compiled on FreeBSD
by Roger Pau Monné 01 May '15

01 May '15

Hello, I've compiled SeaBIOS on FreeBSD with gcc48, and although the build process succeeds, the resulting binary doesn't fully work. Most functions seem to work fine but there are some int15h functions that don't work properly (ie: they return invalid values). I've compiled SeaBIOS with CONFIG_DEBUG_LEVEL=10 and got the following output (this is from the Xen console): [...] (d4) enter handle_1a: (d4) a=00000200 b=00000000 c=00001725 d=00003400 ds=4cf0 es=9eb8 ss=dd00 (d4) si=00000004 di=00000000 bp=00000000 sp=0000fe66 cs=0000 ip=9336 f=0242 (d4) enter handle_1a: (d4) a=00000200 b=00000000 c=00001725 d=00003400 ds=4cf0 es=9eb8 ss=dd00 (d4) si=00000004 di=00000000 bp=00000000 sp=0000fe66 cs=0000 ip=9336 f=0242 (d4) enter handle_1a: (d4) a=00000200 b=00000000 c=00001725 d=00003400 ds=4cf0 es=9eb8 (XEN) irq.c:386: Dom4 callback via changed to Direct Vector 0x93 (XEN) irq.c:276: Dom4 PCI link 0 changed 5 -> 0 (XEN) irq.c:276: Dom4 PCI link 1 changed 10 -> 0 (XEN) irq.c:276: Dom4 PCI link 2 changed 11 -> 0 (XEN) irq.c:276: Dom4 PCI link 3 changed 5 -> 0 (d4) enter handle_15: And that's all, there's no line containing the register values. I'm quite lost at figuring what's going on, so any help about how to proceed in order to debug this is highly appreciated. Thanks, Roger.

We will discuss the current state of affairs and plan for the future of KVM, its surrounding infrastructure, and management tools. Mark your calendar and join us in advancing KVM. http://events.linuxfoundation.org/events/kvm-forum/ This year, the KVM Forum is moving back to North America. We will be colocated with the Linux Foundation's LinuxCon North America, CloudOpen North America, ContainerCon and Linux Plumbers Conference events. Attendees of KVM Forum will also be able to attend a shared hackathon event with Xen Project Developer Summit on August 18, 2015. We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2015. http://events.linuxfoundation.org/cfp Suggested topics: KVM/Kernel * Scaling and optimizations * Nested virtualization * Linux kernel performance improvements * Resource management (CPU, I/O, memory) * Hardening and security * VFIO: SR-IOV, GPU, platform device assignment * Architecture ports QEMU * Management interfaces: QOM and QMP * New devices, new boards, new architectures * Scaling and optimizations * Desktop virtualization and SPICE * Virtual GPU * virtio and vhost, including non-Linux or non-virtualized uses * Hardening and security * New storage features * Live migration and fault tolerance * High availability and continuous backup * Real-time guest support * Emulation and TCG * Firmware: ACPI, UEFI, coreboot, u-Boot, etc. * Testing Management and infrastructure * Managing KVM: Libvirt, OpenStack, oVirt, etc. * Storage: glusterfs, Ceph, etc. * Software defined networking: Open vSwitch, OpenDaylight, etc. * Network Function Virtualization * Security * Provisioning * Performance tuning =============== SUBMITTING YOUR PROPOSAL =============== Abstracts due: May 1, 2015 Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length up to 45 minutes. Also include in your proposal the proposal type -- one of: - technical talk - end-user talk Submit your proposal here: http://events.linuxfoundation.org/cfp Please only use the categories "presentation" and "panel discussion" You will receive a notification whether or not your presentation proposal was accepted by May 29, 2015. Speakers will receive a complimentary pass for the event. In the instance that your submission has multiple presenters, only the primary speaker for a proposal will receive a complementary event pass. For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, focus on work that needs to be done, difficulties that haven't yet been solved, and on decisions that other developers should be aware of. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2015_BOF Let people you think might be interested know about it, and encourage them to add their names to the wiki page as well. Please try to add your ideas to the list before KVM Forum starts. PANEL DISCUSSIONS If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your abstract. We will request full biographies if a panel is accepted. =============== HOTEL / TRAVEL =============== KVM Forum 2015 will be taking place at the Sheraton Seattle Hotel. We are pleased to offer attendees a discounted room rate of US$199/night (plus applicable taxes) which includes wifi in your guest room. http://events.linuxfoundation.org/events/kvm-forum/attend/hotel-and-travel includes further information on the Sheraton Seattle and the discounted room rate, as well as on transportation and parking options for the hotel. =============== IMPORTANT DATES =============== Notification: May 29, 2015 Schedule announced: June 3, 2015 Event dates: August 19-21, 2015 Thank you for your interest in KVM. We're looking forward to your submissions and seeing you at the KVM Forum 2015 in August! -your KVM Forum 2015 Program Committee Please contact us with any questions or comments.
