| | | | | | | | | | | | | | | | | | | | | | | | | 3-entry PA-only promote, V7 execution swap; compile-verified, untested) Replays the decoded real 570.144 GSP client compute-context sequence on the ladder, additive to modes 0-34: - TSG fault-method buffers: one 0xa06c010a on the ladder TSG with two 0x2000 {base,size,alignment=1,addressSpace,cache} descriptors + zero bar2Addr words + numValidEntries=2; server FBMEM first, registered host sysmem fallback (capture order TSG -> faults -> share -> channel). - FERMI_CONTEXT_SHARE_A (0x9067) reuse of the mode-34 helper (ladder TSG, SHARED_MANAGEMENT VAS, flags SYNC -> VEID 0). - V7 channel 0xcaf000a0: class 0xc46f, TSG parent, hVASpace=0, hContextShare, captured flags 0x00201320 and internalFlags 0x1d, engineType 0, sysmem hObjectError/errorNotifierMem, FBMEM instance/ramfc, sysmem USERD. - One atomic 3-entry GPU_PROMOTE_CTX on V7 (MAIN/PM/PATCH, PA-only, physAttr 4, bInitialize=1, bNonmapped=1) before any 0xc5c0 construct. - TURING_COMPUTE_A (0xc5c0) on V7 after the accepted promote; execution channel swapped to V7 for stage 4 BIND/SCHEDULE/token/GR-sem and forwarding (V6 allocated but unscheduled; its promote suppressed). - Mode-35-only golden9 entry refresh: FECS_EVENT attr=5 with the ctx-window VA in the physAddr field, PRIV_ACCESS_MAP va=0/bNonmapped=1. - gr_promote clamp/param doc extended to 0..35.

* vgsp: add read-only gsp-phys-reg-probe debugfs register snapshotArthur Hanson Rasmusson6 days
| | | | | | | | | | | | Add a read-only BAR0 register-liveness probe at /sys/kernel/debug/vgsp/gsp-phys-reg-probe that prints "name addr value" for the PMC chip-id/clock gate, PGRAPH status/fault, SKED/HWW and FECS/GPCCS falcon state, the front-end QMD virtual-window controls and the GSP context registers, followed by decoded field lines. Read-only (readl only); additive to gsp_phys_boot_debugfs_init(); no ladder logic changed. Used to distinguish a clock/power-gated engine from a halted or running one during a physical cycle.
* vgsp: mode 34 - context-share golden execution lane (compile-verified, untested)Arthur Hanson Rasmusson6 days
| | | | | | | | | | | | | Mode 34 allocates FERMI_CONTEXT_SHARE_A (0x9067) on the ladder TSG before the golden replay; the replay's golden channel A (0xcaf00054) attaches to the share with hVASpace=0 and keeps the captured unwired shape, runs its 9-entry promote and carries TURING_A (0xc597) plus a TURING_COMPUTE_A (0xc5c0, handle 0xcaf00090). V6 (0xcaf00034) attaches to the same share, constructs no class object of its own, and its FWCLIENT promote is suppressed; stage 4 and the forwarded launches run on V6 in A's shared VEID/subcontext. Default off; all paths gated by gsp_phys_rmcall_gr_promote=34. New pr_info cycle landmarks for the share alloc, A alloc/promote, A construct (rpc_result), V6 alloc and the instance/RAMFC decode. No hardware run.

* vgsp: install the Tier-2 scratch-pool window spine via PDE_UPDATE + IQ2M ↵Arthur Hanson Rasmusson6 days
| | | | | | | | | | | | | | | | | | | sentinel diagnostic - The Tier-2 shadow VAs (0x200000 + page<<21 + line<<16) had no PTE chain in the engine's table view on the shared-management VAS: pdb_build's client PD0 spine for the guest scratch PT pool is discarded by the server's root migration, so every param/program/release/alias leg the launch rewrites to a shadow VA was unreachable by the engine. Install each scratch pool window lazily through DMA_UPDATE_PDE_2 (same control shape as the Tier-1 installer, pool chunk as the leaf PT) the first time a shadow line in it is consumed; shared VAS only, idempotent via rmcall_guest_pt_win_mask. m17 confirmed the install is accepted (pdeIndex=1 VA 0x200000 status 0x0). - IQ2M sentinel: write 0xdeadbeef to the inline-QMD destination word 0 after the prewrite and report iq2m=ran/not-run in the post-mortem so 'engine stalled before the inline window' is distinguishable from 'QMD deposited but not executed' without a server capture.
* vgsp: mode-29 construct-last golden execution lane + fetch-aligned USERD ↵Arthur Hanson Rasmusson6 days
| | | | | | | | | | | | | | | | | control offset - New mode 29 (GOLDEN_EXEC_LAST): identical to mode 28 but skips the TURING_COMPUTE_A alloc on the client-wired golden channel (every GR object construct there blocks RM); stage 3 completes with the golden handle swapped and BIND/GPFIFO_SCHEDULE/token are accepted. Param clamp 0..29. - Shape bits: bit6 TSG parent (alloc accepted, same no-fetch), bit7 host USERD control offset 0 (THE FETCH FIX: the server applies the sysmem userd_mem base directly and ignores the captured USERD_INDEX_VALUE=3, so GP_PUT/GP_GET live at +0x8c/+0x88; m14: GP_GET advanced 1), bit8 pre-promote compute object (invalid order: RM blocked -110 + NOCAT 0x52a8b04). - Failure diagnostics: REAL GR SEM FAILED now dumps both candidate USERD control offsets (ctl and alt).
* vgsp: PRIV VA-only booking bit + verify the exact slot before consuming ↵Arthur Hanson Rasmusson6 days
| | | | | | | | | | | | | unreadable CE entries - fwclient mask bit 15 (0x8000): book the PRIV_ACCESS_MAP VA (the FWCLIENT entry form is init-only; the golden9 form carries the VA at VA_GOLDEN9_PRIV). Accepted on V6 (status 0), completing the maximal promoted context. - gsp_sema_service: svc_entry_want_reached() verifies the exact tracking slot against entry_want before the three unreadable-CE consume shortcuts treat the entry as delivered; when the slot lags, re-seed the expectation and let svc_fake_release author or queue the exact slot (UVM registration stall pair with the pool-VA verified-resolver queue).
* vgsp: golden-exec shape bisection + fwclient per-entry promotion + pool-VA ↵Arthur Hanson Rasmusson6 days
| | | | | | | | | | | | | | | | | | | | | | | | | stall fix - Mode 28 golden execution lane behind gsp_phys_rmcall_gr_promote=28 with a shape bitmask (gsp_phys_rmcall_golden_exec_shape: ring / entries=8 / sysmem USERD / USERD size / hObjectBuffer=VAS / skip replay TURING_A) and a USERD control-offset helper. Finding: the RM-managed golden channel hangs any GR object construct (-110, no assert) as soon as client submission wiring (ring or sysmem USERD) is attached, so only the captured server-owned shape constructs; the machinery is kept for future wiring ideas. - fwclient mask bit 11 (0x800): send each non-MAIN FWCLIENT promote entry as its own one-entry control and continue past refusals. V6 acceptance matrix: PM, PATCH, PRIV_ACCESS_MAP, UNRESTRICTED_PRIV_ACCESS_MAP accepted, FECS_EVENT refused 0x1f. - fwclient mask bit 12 (0x1000): golden9 VA-only global bookings (BUNDLE_CB, PAGEPOOL, ATTRIBUTE_CB, RTV_CB_GLOBAL) accepted on V6; bits 13/14 (0x2000/0x4000): FECS PA-only (refused 0x1f) and FECS VA-only (accepted). - gsp_phys_rmcall_srv_main_ignore: ignore a server-reported MAIN in the srv-ctx commit and force the client INITIALIZE_CTX + VA-only fallback. - gsp_sema_service: pool semaphores never fall back to the learned map; queue the absolute release via svc_pending_add until svc_pool_pa_resolve succeeds, and judge pool slots through the verified resolver in svc_apply_pending and the release decode (UVM registration stall fix).

|
* vgsp: alias-map indirect high-VA GR pages and fix up shadow pointersArthur Hanson Rasmusson7 days
| | | | | | | | | The mail kernel's output buffer has no QMD pointer word; the engine reaches it through a pointer inside the parameter bank, so the Tier-1 refusal at its high VA killed the launch. Alias-map such a page's guest HPA at a fresh ladder line and rewrite every matching 8-byte pointer inside the shadowed copy pages (param/program) to the alias, so engine writes land in the guest's own page and the guest's DtoH sees them.
* vgsp: track shadow ranges per record for multi-page GR buffersArthur Hanson Rasmusson7 days
| | | | | | | The inline-record path appends pages after the pointer pages, so the adjacent-entry heuristic missed the second param page. Record each shadowed range (base guest VA, line, mapped PTE count) and extend any page that continues a recorded range, up to 16 pages per 128 B line.
* vgsp: contiguous shadow PTEs for multi-page GR buffers (R4)Arthur Hanson Rasmusson7 days
| | | | | | | | | The mail launch's param buffer spans two pages but the QMD names only the base page. The second page has no pointer word, so the Tier-2 shadow path skipped it and the launch was refused. Map a page with no pointer word that is contiguous with the previous shadow-mapped page into the next PTE of the same 128 B fetch line (each line covers up to 16 consecutive 4 KB pages), keeping the rewritten base-pointer buffer contiguous for the engine.
* vgsp: raise GR forward shadow pool to 24 pagesArthur Hanson Rasmusson7 days
| | | | | | | The mail launch has 8 pointer/QMD pages plus up to two release/sem shadow lines; the 4-page pool exhausted and refused the launch even with the HPA-copy fallback. 24 covers the 16-page launch cap plus the two release shadows.
* vgsp: GR forward shadow fallback for high-VA guest pages (R4)Arthur Hanson Rasmusson7 days
| | | | | | | | | | | | The M1 forward captured the guest's mail launch but was refused at Tier-1: the guest's UVM program/param pages live at 0x7d6e... VAs whose 2 MiB window indices are outside this VAS's PDE range, so DMA_UPDATE_PDE_2 returns 0x1f and the launch fell back (bridge disabled) with the guest polling. When the page HPA was resolved on the identity domain, copy the full guest page into the Tier-2 shadow chunk and rewrite the QMD pointer pair, so pages the engine only reads need no inline coverage. Release/sem pages keep their existing direct-alias shadow lines.
* vgsp: golden9k - size every promoted GR ctx buffer from ↵golden-replayArthur Hanson Rasmusson7 days
| | | | | | | | | | | | | | | | | | GET_ENGINE_CONTEXT_PROPERTIES (REAL GR SEM OK) The golden replay promoted 0x1000 placeholders for FECS_EVENT/PRIV/UNR and 1-page VA-only mappings for the four 3D globals; the server's own geometry reports FECS_EVENT 0x10000, PRIV/UNR 0x80000 each, PAGEPOOL 0x20000, ATTRIBUTE_CB 0x7d7400 and RTV_CB_GLOBAL 0x80000 on this TU104. The girmap sizes are wrong for the engine's ctx-init access-map copies and the ctxsw bundle, producing INJECTED_BUNDLE_ERROR + FECS ctxsw TDR on every VAS shape. fwclient-mask bit 10 (0x400) sizes every promoted buffer from the server's GET_ENGINE_CONTEXT_PROPERTIES (0x801707), re-spaces the VAs to per-buffer caps, extends the ctx small-PT pages to six 2 MB windows and promotes the real sizes. Result (golden9k2): golden promote status 0, FWCLIENT MAIN promote status 0, stage 3 complete, REAL GR SEM OK sem=0xc0ffee01 GPGet=1 GPPut=1, clean teardown, no wedge.
