| * | sema-svc: apply releases promptly and decode compute-push releases | Arthur Hanson Rasmusson | 2026-09-28 |
| | | | | | | | | | | | | | | | | | | | The content sweep now: - decodes a release whose method stream continues with any INC_METHOD, not only the CE LAUNCH_DMA group, so the releases at the head of a compute/GR channel's first push are applied too; - remembers releases whose target VA had no translation (deferred list) and retries them every service pass, so a VA->PA injection lands them immediately instead of after the next full sweep; - re-arms the fast sliced sweep for a few seconds after an injection; - treats a channel whose USERD/ring cannot be resolved as stalled, so the sweep keeps looking for the releases its unreadable pushes carry. tools: add per-cdt client-pin helper (sem pages + /dev/nvidia0 windows), sem-page scanner and memprobe fixes (short-read guard, --brief). Live-verified: injecting a client sem page applied 12 deferred releases within a second; the service kept applying (89 -> 202) while cdt ran. | ||

| * | gsp_sema_service: add content rescue for unmapped push-buffer pool VAs | Arthur Hanson Rasmusson | 2026-09-25 |
| - Add expected_sem_payload tracking to svc_channel for CE channels - Implement svc_rescue_push_page() to scan guest RAM for push with expected semaphore release when VA translation fails - Add svc_init_expected_payload() to initialize expected payload from pool - Add rate-limited logging of distinct stalled VAs (svc_log_stalled_va) - Advance expected_sem_payload on successful push decode - Pushes SEMA_MAP_MAX to 65536, SVC_PIN_SLOTS to 32768 for scale | |||
