Comments and license text only: the amd64 kernel builds, every changed script parses.

* starkernel/doe_log.h — DoE (Design of Experiments) CSV logger
|
||
*
|
||
* Emits per-heartbeat-tick CSV rows to the serial log, tagged with
|
||
* [HADES][DOE ] so they can be grepped cleanly from the QEMU log.
|
||
*
|
||
* Each row contains the 12 standard heartbeat snapshot fields plus
|
||
* 3 APIC timer fields from TimeTrustState:
|
||
* apic_ticks, time_trust_q48, variance_q48
|
||
*
|
||
* A header row is printed automatically before the first data row.
|
||
*
|
||
* Always compiled in -- gating moved from a build-time flag
|
||
* (HEARTBEAT_DOE_LOG) to a runtime one (g_doe_log_enabled below) so the
|
||
* same build can run with or without per-tick instrumentation, toggled
|
||
* live via the HB-ON/HB-OFF FORTH words (register_doe_log_words()),
|
||
* no rebuild required.
