Wire up the various existing pieces so that we can implement measured boot on ArmVirtQemu based on the TPM support in QEMU, just like it has been implemented for x86 in OvmfPkg.
The main difference is that on ARM, we first need to discover the TPM base address from the device tree provided by QEMU, as well as the PSCI method used to perform a cold reset. Changes since v1: - use a separate ResetSystemLib instance based on on-demand parsing of the DT, and expose it via the ResetSystem PPI to other client PEIMs - add Laszlo's ack to #1 - incorporate Laszlo's review feedback across the board Cc: ler...@redhat.com Cc: eric.au...@redhat.com Cc: phi...@redhat.com Cc: marcandre.lur...@redhat.com Cc: stef...@linux.ibm.com Cc: l...@nuviainc.com Ard Biesheuvel (5): OvmfPkg/Tcg2ConfigPei: introduce a signalling PPI to depex on ArmVirtPkg/PlatformPeiLib: make PcdLib dependency explicit in .INF ArmVirtPkg/PlatformPeiLib: discover the TPM base address from the DT ArmVirtPkg: implement ArmVirtPsciResetSystemPeiLib ArmVirtPkg/ArmVirtQemu: add optional support for TPM2 measured boot ArmVirtPkg/ArmVirt.dsc.inc | 6 + ArmVirtPkg/ArmVirtPkg.dec | 6 + ArmVirtPkg/ArmVirtQemu.dsc | 75 ++++++ ArmVirtPkg/ArmVirtQemu.fdf | 6 + ArmVirtPkg/ArmVirtQemuFvMain.fdf.inc | 10 + .../ArmVirtPsciResetSystemPeiLib.c | 232 ++++++++++++++++++ .../ArmVirtPsciResetSystemPeiLib.inf | 39 +++ .../Library/PlatformPeiLib/PlatformPeiLib.c | 101 +++++++- .../Library/PlatformPeiLib/PlatformPeiLib.inf | 20 +- OvmfPkg/OvmfPkg.dec | 5 + OvmfPkg/Tcg/Tcg2Config/Tcg2ConfigPei.inf | 6 +- 11 files changed, 491 insertions(+), 15 deletions(-) create mode 100644 ArmVirtPkg/Library/ArmVirtPsciResetSystemPeiLib/ArmVirtPsciResetSystemPeiLib.c create mode 100644 ArmVirtPkg/Library/ArmVirtPsciResetSystemPeiLib/ArmVirtPsciResetSystemPeiLib.inf -- 2.17.1 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
