treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 482

2019-06-19T15:09:52Z

Based on 1 normalized pattern(s): this work is licensed under the terms of the gnu gpl version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 48 file(s).

kvm: selftests: aarch64: dirty_log_test: support greater than 40-bit IPAs

2018-12-21T10:28:30Z

When KVM has KVM_CAP_ARM_VM_IPA_SIZE we can test with > 40-bit IPAs by using the 'type' field of KVM_CREATE_VM. Signed-off-by: Andrew Jones Signed-off-by: Radim Krčmář

kvm: selftests: introduce new VM mode for 64K pages

2018-10-16T22:29:35Z

Rename VM_MODE_FLAT48PG to be more descriptive of its config and add a new config that has the same parameters, except with 64K pages. Signed-off-by: Andrew Jones Signed-off-by: Paolo Bonzini

kvm: selftests: tidy up kvm_util

2018-10-16T22:26:44Z

Tidy up kvm-util code: code/comment formatting, remove unused code, and move x86 specific code out. We also move vcpu_dump() out of common code, because not all arches (AArch64) have KVM_GET_REGS. Signed-off-by: Andrew Jones Signed-off-by: Paolo Bonzini

kvm: selftests: introduce ucall

2018-10-16T22:26:14Z

Rework the guest exit to userspace code to generalize the concept into what it is, a "hypercall to userspace", and provide two implementations of it: the PortIO version currently used, but only useable by x86, and an MMIO version that other architectures (except s390) can use.

kvm: selftests: add basic test for state save and restore

2018-08-06T15:32:04Z

The test calls KVM_RUN repeatedly, and creates an entirely new VM with the old memory and vCPU state on every exit to userspace. The kvm_util API is expanded with two functions that manage the lifetime of a kvm_vm struct: the first closes the file descriptors and leaves the memory allocated, and the second opens the file descriptors and reuses the memory from the previous incarnation of the kvm_vm struct. For now the test is very basic, as it does not test for example XSAVE or vCPU events. However, it will test nested virtualization state starting with the next patch. Signed-off-by: Paolo Bonzini

kvm: selftests: create a GDT and TSS

2018-08-06T15:32:02Z

The GDT and the TSS base were left to zero, and this has interesting effects when the TSS descriptor is later read to set up a VMCS's TR_BASE. Basically it worked by chance, and this patch fixes it by setting up all the protected mode data structures properly. Because the GDT and TSS addresses are virtual, the page tables now always exist at the time of vcpu setup. Signed-off-by: Paolo Bonzini
