RISC-V OpenSBI FW_DYNAMIC: Pass Next-Stage Information Through the Correct Handoff ABI
Diagnose OpenSBI FW_DYNAMIC handoff failures through a2, target-width information layout, early assembly checks and preferred-boot-hart relocation policy.

RISC-V Secondary-Hart Startup: Treat SBI HSM Success as an Asynchronous Transition
Integrate SBI secondary-hart startup through asynchronous HSM states, physical entry and unspecified-register handling, with a separate runtime-ready handshake.
-
RISC-V Floating-Point Context: Save fcsr and Registers Under the FS State Contract
Audit RISC-V floating-point task contexts through fcsr ownership, FS state meanings and conservative dirty tracking rather than assuming FS initializes registers.
-
RISC-V Vector Loops: Advance by the Returned vl Rather Than an Assumed Register Width
Build portable RISC-V strip-mined loops around returned vl, including legal midrange choices, tail policy and caller-clobbered vector configuration.
-
RISC-V Counter Reads: Separate CSR Availability from Privilege Permission
Distinguish RISC-V counter implementation, mcounteren/scounteren access permission and mcountinhibit progression before interpreting profiling results.
-
RISC-V Executable Memory: Synchronize Instruction Fetch on Every Executing Hart
Synchronize newly written RISC-V instructions across local and remote harts, including data-fence ordering, SBI RFENCE errors and migration coverage.
-
BitBake Include Files: Separate Metadata Lookup from Local Source Lookup
Diagnose include/require parser lookup through parent-directory and BBPATH order, expansion timing and missing-file semantics without confusing it with FILESPATH payload lookup.
-
BitBake Fetch Concurrency: Apply number_threads Without Changing Compiler Parallelism
Apply the global do_fetch number_threads flag, trace the scheduler task-name counter and distinguish its cap from compiler jobs and server-wide quotas.
-
BitBake Pressure Limits: Distinguish New-Task Admission from Process Resource Caps
Explain BitBake pressure-based new-task admission, initialization and measurement scope, then separate it from compiler parallelism and hard resource guarantees.
-
U-Boot Command Timeout: Typing Does Not Restart the bootretry Deadline
Diagnose bootretry as a command-input deadline rather than an idle-after-each-character timer.
