From 5eac589d9a7af8f8b321b00398575070b9a88513 Mon Sep 17 00:00:00 2001 From: Arthur Hanson Rasmusson Date: Tue, 22 Sep 2026 02:16:18 -0400 Subject: kernel: floorsweeping masks + interrupt tree + WPR2 race + fn-10 handler - STATIC_KGR_GET_FLOORSWEEPING_MASKS(0x20800a26): TU104 gpcMask=0x3f (6 GPCs), 4 TPC/GPC. numGpcs==0 killed krcWatchdogInit -> RmInitAdapter bailed ('numGpcs > 0' assert at kernel_graphics_object.c:191). - CPU interrupt tree (osVerifyInterrupts): driver accesses VF window at virtualRegPhysOffset=NV_VIRTUAL_FUNCTION_FULL_PHYS_OFFSET(0xB80000)+off, NOT 0x1640 (was watching wrong offset). On LEAF_TRIGGER write, set LEAF/TOP pending bits + inject MSI-X so the sanity-test ISR runs - osVerifySystemEnvironment now passes. - WPR2 race: clear boot state BEFORE CPUCTL=HALTED on Booter-unload kick so WPR2 is down when driver checks kgspIsWpr2Up ('WPR2 is still up'). - Dedicated GSP_RM_FREE(10) handler: echo NVOS00_PARAMETERS + status=NV_OK (proper free_v03_00 form). fn-10 timeout persists despite this - characterized as driver-side reply-matching issue, not content. --- kernel/gsp_emulation.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'kernel/gsp_emulation.h') diff --git a/kernel/gsp_emulation.h b/kernel/gsp_emulation.h index 929003e..6fa69b1 100644 --- a/kernel/gsp_emulation.h +++ b/kernel/gsp_emulation.h @@ -71,6 +71,20 @@ * returns NULL) so the health check always passes. */ #define GSP_EMU_REG_FALCON_DEBUGINFO 0x110094 +/* CPU interrupt tree (Turing, physical-GPU path): the driver accesses the + * VF window registers at virtualRegPhysOffset = NV_VIRTUAL_FUNCTION_FULL_PHYS_OFFSET + * (0xB80000) + offset. + * LEAF_TRIGGER 0xB80000+0x1640 - write a vector to fire its software interrupt + * LEAF[i] 0xB80000+0x1000+i*4 - per-32-vector pending bits + * TOP[i] 0xB81600+i*4 - per-32-subtree pending bits + * _osVerifyInterrupts (osVerifySystemEnvironment) fires a doorbell software + * interrupt and waits for its ISR; if we don't set the pending state and + * inject MSI-X, the ISR never runs and RmInitAdapter bails. */ +#define GSP_EMU_REG_FULL_PHYS_OFFSET 0xB80000 +#define GSP_EMU_REG_CPU_INTR_LEAF_TRIGGER (GSP_EMU_REG_FULL_PHYS_OFFSET + 0x1640) +#define GSP_EMU_REG_CPU_INTR_LEAF_BASE (GSP_EMU_REG_FULL_PHYS_OFFSET + 0x1000) +#define GSP_EMU_REG_CPU_INTR_TOP_BASE (GSP_EMU_REG_FULL_PHYS_OFFSET + 0x1600) + #define GSP_EMU_CPUCTL_STARTCPU 0x2 #define GSP_EMU_CPUCTL_HALTED 0x10 -- cgit v1.2.3
