Hyper-V provides Isolation VM which has memory encrypt support. Add
hyperv_cc_platform_has() and return true for check of GUEST_MEM_ENCRYPT
attribute.
You need to refresh on how to write commit messages - never say what the
patch is doing - that's visible in the diff itself. Rather, you should
talk about *why* it is doing what it is doing.
Sure. Will update.
bool cc_platform_has(enum cc_attr attr)
{
+ if (hv_is_isolation_supported())
+ return hyperv_cc_platform_has(attr);
Is there any reason for the hv_is_.. check to come before...
Do you mean to check hyper-v before sev? If yes, no special reason.
+
if (sme_me_mask)
return amd_cc_platform_has(attr);
... the sme_me_mask check?
What's in sme_me_mask on hyperv?
sme_me_mask is unset in this case.
