Managed to get the NVMe drive working on my QNAP-TS832X using an upstream Linux build \o/ Not much custom code so far, mostly DT massaging. https://github.com/delroth/linux-qnap-tsx32x/commit/ea69bd0423d6836e05e11e83a4e4a92ee05080e8 … Lost 3h of debugging to having forgotten to set an msi-parent, causing interrupts to never be triggered. Oops.

Next step: not sure -- AHCI might not actually be too bad, most of the custom patches in QNAP's kernel seem to be quirks, not full-on extra drivers. Networking would be nice and convenient, but that's a lot more custom code as far as I can tell.

[ 1.797619] sda: sda1 sda2 sda3 sda4 sda5 [ 1.807139] sd 4:0:0:0: [sda] Attached SCSI disk Well, that was easy. Though right now the 8 drives seem to share one IRQ, which seems suboptimal. One of the quirks hacked in the QNAP kernel is for MSI-X support. Would be nice.
