Re: [PATCH] reset qxl to vga mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


The procedure was:
We sign the driver for Win10 only and then produce 2 driver packages: one for Win 10 (with signed one) and another one for 8.1 (we call it 'compatible') as is. It is signed by RH certificate and has all the respective limitations.

As far as I remember, we built qxldod for Win10 only anyway.

Best regards,

I'm not sure how to release it. We used to bundle it in
spice-guest-tools but there was a signing process too.

I see that virtio-win also bundles spice-guest-tools so, they
ship our ancient release... I see something in preinst for
amd64/w8 on qxldod [0]. Vadim, does virtio-win build/sign qxldod for
some Windows releases with fixes?

Unfortunately qxldod is not a part of the virtio-win drivers build. 
Technically, it should not be a problem to build a new version of qxldod 
driver and submit it to WHQL dashboard for attestation signing. But 
attestation signing works for Win10 drivers only.
