From c9661edb46f087c67ffd9dca7ac30b291503ecd3 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Sun, 15 Nov 2026 15:15:14 -0500 Subject: vgsp: eng59b - do not let the arming launch consume the release carrier; re-arm in the pump The saved-window release carrier was armed inside the pack-completing launch's own build, and the client-first cancel treated that same launch (and its retries) as the next client launch, silently dropping the claim. c762: MME-CARRY-SAVE (win=240 held=68) -> MME-CARRY-ARM mode=release -> the arming launch ran mac=0 (LOAD-ONLY, window dropped, held CALLs still owed) -> no FIRE, no synthetic push, no mac=0x22. Track the arming launch identity (h + push) and keep the claim armed across it; only the MME-PACK-REARM edge (calls actually released), a real consumer, context/handle changes, or a launch error cancels/consumes. Add a pump-side re-arm once pack_done_gen is set, and bounded MME-CARRY-HOLD receipts for every skip. One fire per pack completion, no retries. Build rc 0; validation pending (c762-class boot with sema_gl_mme_pack_release=1). --- kernel/gsp_phys_booter.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'kernel/gsp_phys_booter.h') diff --git a/kernel/gsp_phys_booter.h b/kernel/gsp_phys_booter.h index a27225b..21eb1fc 100644 --- a/kernel/gsp_phys_booter.h +++ b/kernel/gsp_phys_booter.h @@ -597,6 +597,8 @@ void gsp_phys_gr_mme_carry_failed(int rc); */ bool gsp_phys_gr_mme_release_peek(u32 *h_object); bool gsp_phys_gr_mme_release_take(u32 h_object, u32 *held, u32 *win); +void gsp_phys_gr_mme_release_rearm(void); +bool gsp_phys_gr_mme_release_is_arming(u32 h, u64 push); void gsp_phys_gr_mme_release_cancel(const char *reason); void gsp_phys_gr_mme_release_failed(int rc); void gsp_phys_gr_mme_release_complete(void); -- cgit v1.2.3
