From 9b44eb71ca2392606b74a15f7f330482be3e826a Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Mon, 21 Sep 2026 19:42:17 -0400 Subject: kernel: INTR_GET_KERNEL_TABLE subtreeMap = intrInitSubtreeMap_TU102 values Driver's intrCacheIntrFields requires subtree(ACCESS_CNTR=72)=1 within subtreeMap[UVM_OWNED] and UVM_SHARED to be a single subtree. Zeroed map failed RmInitNvDevice state load ('unexpected subtree'). Map matches intrInitSubtreeMap_TU102 (what physical-path guests get from real GSP-RM): ESCHED{3,3} ESCHED_NOTIF{0,0} UVM_OWNED{1,1} UVM_SHARED{2,2}, DEFAULT/RUNLIST/RUNLIST_NOTIF=INVALID(0xFF). Struct retyped to 7x2B; out_params_size spans full struct (driver reads subtreeMap at offset 2052). Verified: probe passes state load, /dev/nvidia0 persists. --- kernel/gsp_rm_tu104.h | 19 ++++++++++++++++++- 1 file changed, 18 insertions(+), 1 deletion(-) (limited to 'kernel/gsp_rm_tu104.h') diff --git a/kernel/gsp_rm_tu104.h b/kernel/gsp_rm_tu104.h index ddd735f..d05d453 100644 --- a/kernel/gsp_rm_tu104.h +++ b/kernel/gsp_rm_tu104.h @@ -74,10 +74,27 @@ struct tu104_intr_table_entry { u32 vectorNonStall; }; +/* NV2080_INTR_CATEGORY_SUBTREE_MAP (ctrl2080internal.h) - 2 bytes */ +struct tu104_intr_subtree_map { + u8 subtreeStart; + u8 subtreeEnd; +}; + +/* NV2080_INTR_CATEGORY enum */ +#define TU104_INTR_CATEGORY_DEFAULT 0 +#define TU104_INTR_CATEGORY_ESCHED_DRIVEN_ENGINE 1 +#define TU104_INTR_CATEGORY_ESCHED_DRIVEN_ENGINE_NOTIFICATION 2 +#define TU104_INTR_CATEGORY_RUNLIST 3 +#define TU104_INTR_CATEGORY_RUNLIST_NOTIFICATION 4 +#define TU104_INTR_CATEGORY_UVM_OWNED 5 +#define TU104_INTR_CATEGORY_UVM_SHARED 6 +#define TU104_INTR_CATEGORY_ENUM_COUNT 7 +#define TU104_INTR_INVALID_SUBTREE 0xFF + struct tu104_intr_get_kernel_table_params { u32 tableLen; struct tu104_intr_table_entry table[TU104_INTR_TABLE_MAX_SIZE]; - u32 subtreeMap[7]; /* NV2080_INTR_CATEGORY_* count */ + struct tu104_intr_subtree_map subtreeMap[TU104_INTR_CATEGORY_ENUM_COUNT]; }; /* NV2080_CTRL_GPU_CONSTRUCTED_FALCON_INFO (ctrl2080gpu.h) - 20 bytes */ -- cgit v1.2.3
