Subject: [PATCH v6 4/9] KVM: VMX: Move MSR_IA32_VMX_BASIC bit defines to asm/vmx.h
Date: Fri, 8 Mar 2024 17:27:20 -0800 [thread overview]
Message-ID: <20240309012725.1409949-5-seanjc@google.com> (raw)
In-Reply-To: <20240309012725.1409949-1-seanjc@google.com>
From: Xin Li <xin3.li@intel.com>
Move the bit defines for MSR_IA32_VMX_BASIC from msr-index.h to vmx.h so
that they are colocated with other VMX MSR bit defines, and with the
helpers that extract specific information from an MSR_IA32_VMX_BASIC value.
Opportunistically use BIT_ULL() instead of open coding hex values.
Opportunistically rename VMX_BASIC_64 to VMX_BASIC_32BIT_PHYS_ADDR_ONLY,
as "VMX_BASIC_64" is widly misleading. The flag enumerates that addresses
are limited to 32 bits, not that 64-bit addresses are allowed.
