Severity: moderate

Justification: Range is dominated by bug fixes (CCE pending-bits saturation, BE interrupt priority ordering, instret_en CSR mode, mtval/stval on instruction access fault, CCE-decode-dir-case) and verification/CI improvements (Xcelium support, coverage in VCS/Verilator, Verilator 5.045 associative-array fix). A handful of small features (icache tracer plusargs, dramsim3 mkdir-before-move). No top-level RTL architectural changes for the BlackParrot core itself — bug fixes touch existing modules (bp_be_csr, CCE) but don't reshape the pipeline.

What changed (highlights)

• CSR fixes — bp_be_csr: instret_en uses is_s_mode not is_m_mode (#1262); write faulting PC to mtval/stval on instruction access fault (#1018 / #1270).
• Interrupt priority ordering — bp_be interrupt priority fix (#1287 / #1288).
• CCE fixes — pending-bits saturation fix (#1292); decode-dir-case bug fix.
• Verification — Verilator 5.045 associative-array nonblocking fix (#1290); Icache tracer migrated to plusargs (#573 / #1257); cosim DPI-C uses plusargs for program name (#1277); mem-noc CID aliasing safety check (#391 / #1245).
• MSHR / interface verifier — enhanced derived cache + flit stats (#1241); fix MSHR parameter check + typos (#1244); inline docs on bp_be_commit_pkt_s (#1239).
• Tooling — Xcelium support added (#1304); VCS + Verilator coverage added (#1305); CI scripts bumped to v1p1 (#1291); dramsim3 makefile mkdir-before-mv (#1279).
• Docs / housekeeping — root .editorconfig (#1247); export BP_DIR from Makefile.env (#1250); BlackParrot macOS Docker setup guide (#1252); README/eval_guide typo fixes; v2.1 release date in README; platform address maps + routing details (#1278); CCE tracer signal usage fix (#1274); PR template link update.

Recommendation

Update opportunistically — CSR and interrupt fixes are correctness improvements that HighTide's bp_uno / bp_quad variants should pick up; no major RTL reshaping. Worth a clean re-baseline of the existing _final flows once the bump lands. Re-verify the CTS-0105 workaround (#10177, ours in 81b0ed4b) still applies after the bump.
