Hi freebsd-hackers@, CC'd freebsd-current@,
I hope you all had a wonderful holiday season.
I recently got a HP Spectre x360 13t-aw200 which is an Intel
TigerLake-based laptop. It has the Intel "Evo" branding and an "Optane"
SSD which I disabled (so I can get a "second" SSD).
On the Spectre, the NVMe is not detected: https://imgur.com/a/ighTwHQ
I don't know if it is HP or Intel, but the VMD IDs device id is
8086:9a0b. I'm guessing Intel since Dell laptops (XPS, Vostro) also have
this device ID [1].
Sadly, NVMe RAID is forced on this laptop.
I wrote a rough patch to add the device IDs, and the patch is below:
--- a/sys/dev/vmd/vmd.c
+++ b/sys/dev/vmd/vmd.c
@@ -66,13 +66,20 @@ struct vmd_type {
#define INTEL_VENDOR_ID 0x8086
#define INTEL_DEVICE_ID_VMD 0x201d
#define INTEL_DEVICE_ID_VMD2 0x28c0
+#define INTEL_DEVICE_ID_VMD3 0x9a0b
static struct vmd_type vmd_devs[] = {
{ INTEL_VENDOR_ID, INTEL_DEVICE_ID_VMD, "Intel Volume
Management Device" },
{ INTEL_VENDOR_ID, INTEL_DEVICE_ID_VMD2, "Intel Volume
Management Device" },
+ { INTEL_VENDOR_ID, INTEL_DEVICE_ID_VMD3, "Intel Volume
Management Device" },
{ 0, 0, NULL }
However, I get a panic whenever I use this patch:

Without this patch, I am able to boot fine but can't see the SSD or any
nvd* devices beyond a "none" device in `pciconf -lv`.
For those who know about PCI/ACPI subsystems, can you please tell me
what's going wrong?
I'm still debugging in the meanwhile, but am no expert on PCI/ACPI
subsystems. I may know more than most PC builders or CS grads, but not
really enough to do it full-time.
The Spectre's SSD works fine with Windows 10 (obviously) and Linux
(Fedora and Debian tested).
Best,
Neel Chauhan
