I have tried booting latest -current snapshot on 2019 macbook pro 16, and noticed that nvme driver didn't attach, as class reported is 0x018002 and not 0x010802 that we expect in nvme_pci.c. The following linux changes seem to be related: https://github.com/torvalds/linux/commit/66341331ba0d2de4ff421cdc401a1e34de50502a https://github.com/torvalds/linux/commit/d38e9f04ebf667d9cb8185b45bff747485f1d3e9 I have tried adding the exact PCI IDs, but that also fails as number of msix vectors seems to be 0 in nvme_ctrlr_setup_interrupts() and nvme_ctrlr_configure_intx() fails with "unable to allocate shared IRQ". Any hints on how to proceed here? pciconf excerpt: none7@pci0:4:0:0: class=0x018002 rev=0x01 hdr=0x00 vendor=0x106b device=0x2005 subvendor=0x106b subdevice=0x1800 vendor = "Apple Inc." device = "ANS2 NVMe Controller" class = mass storage bar [10] = type Prefetchable Memory, range 64, base 0xc0400000, size 419304, enabled bar [18] = type Prefetchable Memory, range 64, base 0xc1400000, size 524288, enabled bar [20] = type Prefetchable Memory, range 64, base 0xc1600000, size 65536, enabled cap 01[40] = powerspec 3 supports D0 D3 current D0 cap 05[50] = MSI supports 8 messages, 64 bit cap 10[70] = PCI-Express 2 endpoint max data 256(256) RO NS link x4(x4) speed 8.0(8.0) ASPM L1(L1) ClockPM enabled ecap 0001[100] = AER 2 0 fatal 0 non-fatal 1 corrected ecap 0019[148] = PCIe Sec 1 lane errors 0 ecap 0018[168] = LTR 1 ecap 001e[170] = L1 PM Substated 1 ecap 000b[180] = Vendor [1] ID 0002 Rev 1 Length 256 ecap 0015[280] = Resizable BAR 1
