[9front] ThinkPad X1 Yoga 3rd Gen vs WWAN NvME

[sl]

openbsd was able to format this and mount it.

9front recognizes it as sdN, but the kernel bails out:

sdN (nvme): create completion queue: status 102

sysinfo:

any ideas?

The status code 0x102 means invalid queue size (§3.3.3.2.1.2).

We should check the maximum queue entries supported (mqes)
field of the controller capabilities before setting up the queues
(§5.4.1). Then /sys/src/9/port/sdnvme.c:/Overkill could go away.

Cheers,

my friend tried to install 9front on their pc, and they
had this exact problem. the motherboard was a gigabyte
b660m and the nvme controller was this:

02:00.0 Non-Volatile memory controller: Silicon Motion, Inc.
SM2263EN/SM2263XT SSD Controller (rev 03)

fyi, i tried another drive and discovered the following model nvme ssd works fine in 9front:

Western Digital SN520 SDAPMUW-256G-1101

the machine can't boot directly from the wwan slot, but booting the kernel from a usb stick and then mounting root from the nvme ij the wwan slot works fine.
