On P5 chips, the maximum number\nof concurrent TPA is 256 and the amount of memory we allocate is order-5\non systems using 4K pages.  Memory allocation failure has been reported:\n\nNetworkManager: page allocation failure: order:5, mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0-1\nCPU: 15 PID: 2995 Comm: NetworkManager Kdump: loaded Not tainted 5.10.156 #1\nHardware name: Dell Inc. PowerEdge R660/0M1CC5, BIOS 0.2.25 08/12/2022\nCall Trace:\n dump_stack+0x57/0x6e\n warn_alloc.cold.120+0x7b/0xdd\n ? _cond_resched+0x15/0x30\n ? __alloc_pages_direct_compact+0x15f/0x170\n __alloc_pages_slowpath.constprop.108+0xc58/0xc70\n __alloc_pages_nodemask+0x2d0/0x300\n kmalloc_order+0x24/0xe0\n kmalloc_order_trace+0x19/0x80\n bnxt_alloc_mem+0x1150/0x15c0 [bnxt_en]\n ? bnxt_get_func_stat_ctxs+0x13/0x60 [bnxt_en]\n __bnxt_open_nic+0x12e/0x780 [bnxt_en]\n bnxt_open+0x10b/0x240 [bnxt_en]\n __dev_open+0xe9/0x180\n __dev_change_flags+0x1af/0x220\n dev_change_flags+0x21/0x60\n do_setlink+0x35c/0x1100\n\nInstead of allocating this big chunk of memory and dividing it up for the\nconcurrent TPA instances, allocate each small chunk separately for each\nTPA instance.  This will reduce it to order-0 allocations.\n\ud83d\udccf Published: 2025-05-02T15:56:07.666Z\n\ud83d\udccf Modified: 2025-05-02T15:56:07.666Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/16f3aae1aa2dd89bc8d073a67f190af580386ae9\n2. https://git.kernel.org/stable/c/d16701a385b54f44bf41ff1d7485e7a11080deb3\n3. https://git.kernel.org/stable/c/20fd0607acbf9770db9b99e3418dd75614f80b6c\n4. https://git.kernel.org/stable/c/fcae40e65802547def39b4deaa2ae38a29864d81\n5. https://git.kernel.org/stable/c/ad529d1fae1565d38f929479d4ea8aea90054bd2\n6. https://git.kernel.org/stable/c/accd7e23693aaaa9aa0d3e9eca0ae77d1be80ab3", "creation_timestamp": "2025-05-02T16:16:10.000000Z"}
