Subject: [PATCH v8 4/9] KVM: VMX: Report tertiary_exec_control field in dump_vmcs()
Date:   Mon, 11 Apr 2022 17:04:42 +0800
Message-Id: <20220411090447.5928-5-guang.zeng@intel.com>
In-Reply-To: <20220411090447.5928-1-guang.zeng@intel.com>
References: <20220411090447.5928-1-guang.zeng@intel.com>
Precedence: bulk

From: Robert Hoo <robert.hu@linux.intel.com>

Add tertiary_exec_control field report in dump_vmcs(). Meanwhile,
reorganize the dump output of VMCS category as follows.

Before change:
*** Control State ***
 PinBased=0x000000ff CPUBased=0xb5a26dfa SecondaryExec=0x061037eb
 EntryControls=0000d1ff ExitControls=002befff

After change:
*** Control State ***
 CPUBased=0xb5a26dfa SecondaryExec=0x061037eb TertiaryExec=0x0000000000000010
 PinBased=0x000000ff EntryControls=0000d1ff ExitControls=002befff
