SubjectRE: [PATCH v3 07/11] hv_netvsc: Use HV_HYP_PAGE_SIZE for Hyper-V communication
Date
From: Boqun Feng <boqun.feng@gmail.com> Sent: Thursday, September 10, 2020 7:35 AM

> When communicating with Hyper-V, HV_HYP_PAGE_SIZE should be used since
> that's the page size used by Hyper-V and Hyper-V expects all
> page-related data using the unit of HY_HYP_PAGE_SIZE, for example, the
> "pfn" in hv_page_buffer is actually the HV_HYP_PAGE (i.e. the Hyper-V
> page) number.
>
> In order to support guest whose page size is not 4k, we need to make
> hv_netvsc always use HV_HYP_PAGE_SIZE for Hyper-V communication.
