HCL - Sony SVF15A1C5E

[r.fl...@openmailbox.org]

I tested if this laptop supports VT-d both with `qubes-hcl-report` and
`xl dmesg`. Furthermore BIOS supports Intel VT.
However I cannot determine what is the PCH of this laptop. I think that
it's a HM76 chipset but, from its ark page, it does not support VT-d.
How can I determine it correctly?
I also attached lspci's output.

I opened the laptop. I can confirm that it's a SLJ8E BD82HM76 PCH. So
the motherboard does not support VT-d.
So how both hcl and xen confirm that this laptop supports IOMMU?

the HCL script is pretty easy to read. You can check how it is decide
vt-d support.

it is actually relaying on xen, and parsing the output of these commands
:
xl info
xl dmesd

If you believe it is a false report, send us the support files as well
for further investigation.

I didn't know that `qubes-hcl-report` is a bash shell script. I've just
saw how VT-d support is recognized. Probably there is a problem with `xl
info`. It prints actually that this laptop supports VT-d.
It's strange..

However I attached support files. I hope that we can resolve this
'mistery'.

According the data you sent me, your device is an Ivy Bridge + i7-3537U
https://pci-ids.ucw.cz/read/PC/8086/0154

According the intel official docs, this system is supprts vt-x and
vt-d as well:

mbedded-3rd-generation-intel-core-i7-processor-with-mobile-intel-hm76-ch
ipset.html

http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/7
- -series-chipset-pch-datasheet.pdf


So Xen (and qubes HCL script) reports about vt-d is seems to be true :)
