Worked on stabilizing TPM-enabled firmware builds for the microsoft/mu_tiano_platforms repository, focusing on resolving prebuild crashes in QEMU/Q35 environments. Addressed a persistent build issue by removing a stale Tpm2DebugLib mapping, which restored successful GCC5/X64 builds for both DEBUG and RELEASE configurations with TPM_ENABLE set to TRUE. Validated the end-to-end boot process using QEMU and swtpm, confirming proper TPM2Startup execution and accurate PCR7 measurements without asserts. Leveraged expertise in C programming, build system management, and firmware development to enhance CI reliability, enabling TPM-enabled testing pipelines and reducing build fragility across UEFI MU_BASECORE and related tooling.

Jun 1, 2026June 2026 monthly summary for microsoft/mu_tiano_platforms focused on stabilizing TPM-enabled firmware builds and validating end-to-end boot paths in QEMU/Q35. Delivered a targeted firmware build fix by removing a stale Tpm2DebugLib mapping, eliminating TPM_ENABLE=TRUE prebuild crashes and restoring functional prebuilds. Commit: 86f64641879f4a9a4ef0ab0ec761a1815e235cb0. This change removed a vestigial mapping in MU_BASECORE and allowed successful GCC5/X64 builds for both DEBUG and RELEASE with TPM_ENABLE=TRUE. End-to-end validation confirmed QEMU boot with swtpm vTPM; PEI TPM2Startup succeeded; PCR banks reallocated to SHA256; DXE Tcg2Dxe installs Tcg2Protocol and measures PCR7 (SecureBoot/PK/KEK/db/dbx) with no asserts. All prebuild plugins (OverrideValidation) passed, reducing build fragility and enabling TPM-enabled testing in CI. Technologies exercised include UEFI MU_BASECORE, QEMU/Q35, EDK2 DSC/INF changes, prebuild/override-validation tooling, swtpm, and GCC5/X64 cross-compilation.
