git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for Linux 5.16 - More progress on the protected VM front, now with the full fixed feature set as well as the limitation of some hypercalls after initialisation. - Cleanup of the RAZ/WI sysreg handling, which was pointlessly complicated - Fixes for the vgic placement in the IPA space, together with a bunch of selftests - More memcg accounting of the memory allocated on behalf of a guest - Timer and vgic selftests - Workarounds for the Apple M1 broken vgic implementation - KConfig cleanups - New kvmarm.mode=none option, for those who really dislike us
2021-10-22kvm: x86: mmu: Make NX huge page recovery period configurableJunaid Shahid1-1/+8
Currently, the NX huge page recovery thread wakes up every minute and zaps 1/nx_huge_pages_recovery_ratio of the total number of split NX huge pages at a time. This is intended to ensure that only a relatively small number of pages get zapped at a time. But for very large VMs (or more specifically, VMs with a large number of executable pages), a period of 1 minute could still result in this number being too high (unless the ratio is changed significantly, but that can result in split pages lingering on for too long). This change makes the period configurable instead of fixing it at 1 minute. Users of large VMs can then adjust the period and/or the ratio to reduce the number of pages zapped at one time while still maintaining the same overall duration for cycling through the entire list. By default, KVM derives a period from the ratio such that a page will remain on the list for 1 hour on average.

2021-10-18selftests: KVM: Introduce system counter offset testOliver Upton1-14/+27
Introduce a KVM selftest to verify that userspace manipulation of the TSC (via the new vCPU attribute) results in the correct behavior within the guest.

2021-10-18KVM: x86: Expose TSC offset controls to userspaceOliver Upton1-0/+57
To date, VMM-directed TSC synchronization and migration has been a bit messy. KVM has some baked-in heuristics around TSC writes to infer if the VMM is attempting to synchronize. This is problematic, as it depends on host userspace writing to the guest's TSC within 1 second of the last write. A much cleaner approach to configuring the guest's views of the TSC is to simply migrate the TSC offset for every vCPU. Offsets are idempotent, and thus not subject to change depending on when the VMM actually reads/writes values from/to KVM. The VMM can then read the TSC once with KVM_GET_CLOCK to capture a (realtime, host_tsc) pair at the instant when the guest is paused.

2021-10-18KVM: x86: Report host tsc and realtime values in KVM_GET_CLOCKOliver Upton1-9/+39
Handling the migration of TSCs correctly is difficult, in part because Linux does not provide userspace with the ability to retrieve a (TSC, realtime) clock pair for a single instant in time. In lieu of a more convenient facility, KVM can report similar information in the kvm_clock structure. Provide userspace with a host TSC & realtime pair iff the realtime clock is based on the TSC. If userspace provides KVM_SET_CLOCK with a valid realtime value, advance the KVM clock by the amount of elapsed time. Do not step the KVM clock backwards, though, as it is a monotonic oscillator.

Recent changes to KVM for arm64 has made it impossible for the host to hibernate or use kexec when protected mode is enabled via the kernel command line. There are people who rely on kexec (for example, developers who use kexec as a quick way to test a new kernel), let's document this change in behaviour, so it doesn't catch them by surprise and we have a place to point people to if it does.

2021-10-11KVM: arm64: Allow KVM to be disabled from the command lineMarc Zyngier1-0/+2
Although KVM can be compiled out of the kernel, it cannot be disabled at runtime. Allow this possibility by introducing a new mode that will prevent KVM from initialising. This is useful in the (limited) circumstances where you don't want KVM to be available (what is wrong with you?), or when you want to install another hypervisor instead (good luck with that).

2021-09-13Merge branch 'gcc-min-version-5.1' (make gcc-5.1 the minimum version)Linus Torvalds4-4/+4
Merge patch series from Nick Desaulniers to update the minimum gcc version to 5.1. This is some of the left-overs from the merge window that I didn't want to deal with yesterday, so it comes in after -rc1 but was sent before. Gcc-4.9 support has been an annoyance for some time, and with -Werror I had the choice of applying a fairly big patch from Kees Cook to remove a fair number of initializer warnings (still leaving some), or this patch series from Nick that just removes the source of the problem. The initializer cleanups might still be worth it regardless, but honestly, I preferred just tackling the problem with gcc-4.9 head-on. We've been more aggressiuve about no longer having to care about compilers that were released a long time ago, and I think it's been a good thing. I added a couple of patches on top to sort out a few left-overs now that we no longer support gcc-4.x. As noted by Arnd, as a result of this minimum compiler version upgrade we can probably change our use of '--std=gnu89' to '--std=gnu11', and finally start using local loop declarations etc. But this series does _not_ yet do that.

2021-09-13Documentation: raise minimum supported version of GCC to 5.1Nick Desaulniers1-1/+1
commit fad7cd3310db ("nbd: add the check to prevent overflow in __nbd_ioctl()") raised an issue from the fallback helpers added in commit f0907827a8a9 ("compiler.h: enable builtin overflow checkers and add fallback code") Specifically, the helpers for checking whether the results of a multiplication overflowed (__unsigned_mul_overflow, __signed_add_overflow) use the division operator when !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW. This is problematic for 64b operands on 32b hosts. Also, because the macro is type agnostic, it is very difficult to write a similarly type generic macro that dispatches to one of: * div64_s64 * div64_u64 * div_s64 * div_u64 Raising the minimum supported versions allows us to remove all of the fallback helpers for !COMPILER_HAS_GENERIC_BUILTIN_OVERFLOW, instead dispatching the compiler builtins. arm64 has already raised the minimum supported GCC version to 5.1, do this for all targets now. See the link below for the previous discussion.
