* kvm-arm64/hvhe: : Support for running split-hypervisor w/VHE, courtesy of Marc Zyngier : : From the cover letter: : : KVM (on ARMv8.0) and pKVM (on all revisions of the architecture) use : the split hypervisor model that makes the EL2 code more or less : standalone. In the later case, we totally ignore the VHE mode and : stick with the good old v8.0 EL2 setup. : : We introduce a new "mode" for KVM called hVHE, in reference to the : nVHE mode, and indicating that only the hypervisor is using VHE. KVM: arm64: Fix hVHE init on CPUs where HCR_EL2.E2H is not RES1 arm64: Allow arm64_sw.hvhe on command line KVM: arm64: Force HCR_E2H in guest context when ARM64_KVM_HVHE is set KVM: arm64: Program the timer traps with VHE layout in hVHE mode KVM: arm64: Rework CPTR_EL2 programming for HVHE configuration KVM: arm64: Adjust EL2 stage-1 leaf AP bits when ARM64_KVM_HVHE is set KVM: arm64: Disable TTBR1_EL2 when using ARM64_KVM_HVHE KVM: arm64: Force HCR_EL2.E2H when ARM64_KVM_HVHE is set KVM: arm64: Key use of VHE instructions in nVHE code off ARM64_KVM_HVHE KVM: arm64: Remove alternatives from sysreg accessors in VHE hypervisor context arm64: Use CPACR_EL1 format to set CPTR_EL2 when E2H is set arm64: Allow EL1 physical timer access when running VHE arm64: Don't enable VHE for the kernel if OVERRIDE_HVHE is set arm64: Add KVM_HVHE capability and has_hvhe() predicate arm64: Turn kaslr_feature_override into a generic SW feature override arm64: Prevent the use of is_kernel_in_hyp_mode() in hypervisor code KVM: arm64: Drop is_kernel_in_hyp_mode() from __invalidate_icache_guest_page() Signed-off-by: Oliver Upton <oliver.upton@linux.dev> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
