During pool populate, Pool 1 triggers NPA_POOL_ERR_INT_R= ANGE repeatedly, followed by Err_intr=3D0x1000: testpmd: create a new mbuf pool : n=3D203456, size=3D2304, soc= ket=3D0 testpmd: preferred mempool ops selected: cn10k_mempool_ops CNXK: npa_q_irq():150 queue_intr=3D0x1 qintx=3D1 CNXK: npa_q_irq():165 Pool=3D1 NPA_POOL_ERR_INT_RANGE (repeats 4 times during mbuf pool populate) Configuring Port 0 (socket 0) CNXK: npa_err_irq():18 Err_intr=3D0x1000 CNXK: npa_err_irq():18 Err_intr=3D0x1000 Pool 1 context at time of error: ptr_start: 0x24808d200 ptr_end: 0x267200000 buf_size: 20 (units of 128 bytes =3D 2560 bytes) buf_offset: 1 count: decreasing across dumps (0x31aa6 =E2=86=92 0x31a91 =E2=86= =92 0x31a79 =E2=86=92 0) op_pc: increasing (0x1a =E2=86=92 0x2f =E2=86=92 0x47 =E2=86=92 0x= 31ac0) stack_pages: 0 (remains zero across all dumps) Notable observations: ---------------------- - stack_pages remains 0 throughout, even as op_pc increases =E2=80=94 sug= gesting buffers are being freed but the stack is not being updated - count decreases to 0 by the final dump, indicating the pool is fully drained - The address range [0x24808d200, 0x267200000) spans ~512 MB, but the mem= pool requests ~203K buffers of 2304 bytes (~447 MB) Expected Result ------------------- No NPA pool range errors. Pool 1 should initialize and populate without triggering NPA_POOL_ERR_INT_RANGE or npa_err_irq interrupts. --=20 You are receiving this mail because: You are the assignee for the bug.=
