From: Saurabh Sengar Date: Fri, 4 Nov 2022 18:38:43 +0000 (-0700) Subject: x86/hyperv: Expand definition of struct hv_vp_assist_page X-Git-Tag: v6.2-rc1~210^2~6 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=202818e1c8519ee301e930484707d7ddace639e0;p=thirdparty%2Flinux.git x86/hyperv: Expand definition of struct hv_vp_assist_page The struct hv_vp_assist_page has 24 bytes which is defined as u64[3], expand that to expose vtl_entry_reason, vtl_ret_x64rax and vtl_ret_x64rcx field. vtl_entry_reason is updated by hypervisor for the entry reason as to why the VTL was entered on the virtual processor. Guest updates the vtl_ret_* fields to provide the register values to restore on VTL return. The specific register values that are restored which will be updated on vtl_ret_x64rax and vtl_ret_x64rcx. Also added the missing fields for synthetic_time_unhalted_timer_expired, virtualization_fault_information and intercept_message.
