[PATCH v2 0/4] s390x/pv: Improve protected VM support

Posted by Cédric Le Goater 1 year, 3 months ago

Hello,

Here is a little series improving error reporting of protected VMs.

Thanks,

C.

Changes in v2:

 - dropped ConfidentialGuestSupportClass handler. The check is now
   done from s390_pv_init() which is called after memory and CPU
   initialization. This gives us a better chance to tune the limits
   correctly.
 - pv_max_cpus now computed from the available size of the response
   buffer of the Read SCP Info Service Call (Thomas)
 
Cédric Le Goater (4):
  s390x/pv: Implement a CGS check helper
  s390x/pv: Check for support on the host
  s390x/pv: Introduce a s390_pv_check() helper for runtime
  s390x/pv: Move check on hugepage under s390_pv_guest_check()
