[Test case] Boot n2d-standard-2 or n2d-standard-64 instances on GCP, issue a lot of IO, and look for DMA overflow or full swiotlb messages on dmesg. [Potential regression] Boot failures should not be discarded when SWIOTLB cannot be allocated. ------------------ ubuntu_boot log_check fails with: WARNING: CPU: 34 PID: 8648 at /build/linux-gcp-5.4-zTWCml/linux-gcp-5.4-5.4.0/kernel/dma/direct.c:35 report_addr+0x33/0x90 From the serial console: [ 137.928758] nvme 0000:00:04.0: overflow 0x0000801f68b5f000+131072 of DMA mask ffffffffffffffff bus mask 0 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.928758] nvme 0000:00:04.0: overflow 0x0000801f68b5f000+131072 of DMA mask ffffffffffffffff bus mask 0 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938685] ------------[ cut here ]------------ Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938691] WARNING: CPU: 34 PID: 8648 at /build/linux-gcp-5.4-zTWCml/linux-gcp-5.4-5.4.0/kernel/dma/direct.c:35 report_addr+0x33/0x90 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938691] Modules linked in: ip6table_filter ip6_tables iptable_filter bpfilter nls_iso8859_1 input_leds pvpanic serio_raw mac_hid sch_fq_codel ib_iser rdma_cm iw_cm ib_cm ib_core iscsi_tcp libiscsi_tcp libiscsi scsi_transport_iscsi ip_tables x_tables autofs4 btrfs zstd_compress raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq raid1 raid0 multipath linear crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel crypto_simd cryptd glue_helper psmouse i2c_piix4 gve Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938712] CPU: 34 PID: 8648 Comm: apt-check Not tainted 5.4.0-1060-gcp #64~18.04.1-Ubuntu Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938712] Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 01/01/2011 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938714] RIP: 0010:report_addr+0x33/0x90 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938716] Code: 48 83 ec 08 48 8b 87 30 02 00 00 48 89 75 f8 48 85 c0 74 26 4c 8b 00 b8 fe ff ff ff 49 39 c0 76 0d 80 3d 47 67 b2 01 00 74 2e <0f> 0b c9 c3 48 83 bf 40 02 00 00 00 75 e9 eb f0 80 3d 2f 67 b2 01 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938716] RSP: 0018:ffffbd77cf99f4e0 EFLAGS: 00010282 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938718] RAX: 0000000000000000 RBX: ffff9773f8b960b0 RCX: 0000000000000000 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938718] RDX: 0000000000000000 RSI: ffff9753ff897448 RDI: 0000000000000000 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938719] RBP: ffffbd77cf99f4e8 R08: 0000000000000305 R09: 0000000000000022 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938719] R10: 000000000016dfee R11: ffffbd77cf99f218 R12: 0000000000020000 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938720] R13: ffff9753abfe9000 R14: 0000000000000001 R15: 0000000000000100 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938723] FS: 00007f55bb523740(0000) GS:ffff9753ff880000(0000) knlGS:0000000000000000 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938723] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938724] CR2: 00007f55b41d6000 CR3: 0000801f6be28000 CR4: 0000000000340ee0 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938726] Call Trace: Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938730] dma_direct_map_page+0xe2/0xf0 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938731] dma_direct_map_sg+0x6c/0xc0 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938735] nvme_queue_rq+0x6fb/0xbd0 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938738] __blk_mq_try_issue_directly+0x139/0x200 Jan 19 12:54:30 b-lgcp-5-4-gcp-5-4-0-n2dstd64-boot kernel: [ 137.938741] ?
