adding support for a possibly unsupported M.2 harddrive?
I have an M.2 SSD for which I have to assume no support exists so far
in NetBSD 9.99.17.
This is an "TREKSTOR M.2 SSD-Modul 64 GB" bought in 2018.
[ 3.739718] wd1 at atabus1 drive 0
[ 3.739718] wd1: <>
[ 3.739718] wd1: drive supports 1-sector PIO transfers, LBA48 addressing
[ 3.739718] wd1: 61057 MB, 124053 cyl, 16 head, 63 sec, 512 bytes/sect x 125045424 sectors
[ 3.739718] wd1: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133), WRITE DMA FUA, NCQ (32 tags)
[ 3.739718] wd1(ahcisata0:1:0): using PIO mode 4, DMA mode 2, Ultra-DMA mode 6 (Ultra/133) (using DMA), NCQ (31 tags)
With fdisk I can see an earlier partition I created on another
system, but making any changes to partitioning etc pp operations
on disk fail (I can reproduce the information how it fails).
Two question paths:
1. How would I go about (no prior device driver writing
experience) adding this to NetBSD?
2. Who / which list would I talk to and which details are necessary
(so far I know fdisk and dmesg provide good details)
to help with adding this to NetBSD?
