[PATCH v3 00/11] Add TPM 2 support
by Stefan Berger 06 Feb '16

06 Feb '16

This series of patches adds TPM 2 support to SeaBIOS in the way previously proposed. v2->v3: - Converted TPM_VERSION_* from enum's to #define's and removed unnecessary cases with TPM_VERSION_NONE in switch statements. - Convert the log_entry internal representation to TPM 2 native format. - Added patch that looks at command tags in the TPM_Passthrough API call and return error code in case of TPM version mismatch. v1->v2: - Addressed most of Kevin's comments. - Added patch for writing logs in TPM 2 format Stefan Stefan Berger (11): tpm: Extend TPM TIS with TPM 2 support. tpm: Factor out tpm_extend tpm: Prepare code for TPM 2 functions tpm: Implement tpm20_startup and tpm20_s3_resume tpm: Implement tpm20_set_timeouts tpm: Implement tpm20_prepboot tpm: Implement tpm20_extend tpm: Implement tpm20_menu tpm: Implement TPM 2's tpm_set_failure part tpm: Write logs in TPM 2 format Filter TPM commands in passthrough API src/hw/tpm_drivers.c | 38 ++- src/hw/tpm_drivers.h | 26 +- src/std/tcg.h | 147 +++++++++ src/tcgbios.c | 900 ++++++++++++++++++++++++++++++++++++++++++--------- 4 files changed, 961 insertions(+), 150 deletions(-) -- 2.4.3

[PATCH 1/2] ehci: Only delay UHCI/OHCI port scan until after EHCI setup completes
by Kevin O'Connor 06 Feb '16

06 Feb '16

EHCI controller setup needs to occur prior to checking any UHCI or OHCI ports to ensure a high speed device is not mistakenly configured on a full speed "companion" controller. However, only the UHCI/OHCI port scan needs to be delayed, not the full UHCI/OHCI controller init. This change moves back the ehci controller setup check until port scan in UHCI/OHCI.

[RFC PATCH v2] fw/pci: Add support for mapping Intel IGD OpRegion via QEMU
by Alex Williamson 04 Feb '16

04 Feb '16

When assigning Intel IGD graphics via QEMU/vfio, the OpRegion for the device may be exposed as a fw_cfg file. Allocate space for this, copy the contents and write the ASL Storage register (0xFC) to point to this buffer. NB, it's possible for QEMU to use the write to the ASL Storage register to map access to the host OpRegion overlapping the allocated buffer, but we shouldn't care if it does.

What about option 2a - SeaBIOS copies from fw_cfg to memory and then programs 0xfc. QEMU can detect the write to 0xfc and choose to map that ram (thus completely ignoring the contents that were just copied in) or it can choose not to map that ram (thus guest uses the contents just copied in). The advantage of this approach is that it is a bit simpler in the firmware (no size probing is needed as the size comes from fw_cfg) and it allows for future flexibility as the choice of mapping can be deferred. Totally untested seabios code below as example. As an aside, if this type of "program a pci register" with a memory address becomes common, we could enhance the acpi-style "linker script" system to automate this.. -Kevin static void intel_igd_opregion_setup(struct pci_device *dev, void *arg) { struct romfile_s *file = romfile_find("etc/igd-opregion"); if (!file) return; void *data = memalign_high(PAGE_SIZE, file->size); if (!data) { warn_noalloc(); return; } int ret = file->copy(file, data, file->size); if (ret < 0) { free(data); return; } pci_config_writel(dev->bdf, 0xFC, (u32)data); }

[RFC PATCH] fw/pci: Add support for mapping Intel IGD OpRegion via QEMU
by Alex Williamson 02 Feb '16

02 Feb '16

The proposed IGD OpRegion support in QEMU via vfio maps the host OpRegion into VM system memory at the address written to the ASL Storage register (0xFC). The OpRegion contains a 16-byte signature followed by a 4-byte size field. Therefore SeaBIOS can allocate a buffer of the typical size (8KB), this results in a matching e820 reserved entry for the range, then write the buffer address to the ASL Storage register, blinking the OpRegion into the VM address space. At that point SeaBIOS can validate the signature and size and remap if necessary. If the OpRegion is larger than 8KB, this would result in any conflicting ranges being temporarily mapped with the OpRegion, which probably needs further discussion on what that could break. Other options might be to use the same algorithm with an obscenely sized initial buffer to make sure we do not overlap, always re-allocating the proper sized buffer, or perhaps we could pass the OpRegion itself or information about the OpRegion through fw_cfg. With the posted kernel series[1] and QEMU series[2] (on top of Gerd's IGD patches[3]), this makes the OpRegion available to the VM and tracing shows that the guest driver does access it.
