2021-08-04Reduce overhead of AlignedAtomic typesAndrei Vagin
AlignedAtomicUint64 is 15 bytes and it takes 16 bytes in structures. On 32-bit systems, variables and structure fields is guaranteed to be 32-bit aligned and this means that we need only 12 bytes to find 8 contiguous bytes.

2021-06-14Fix frame pointer is clobbered before saving vet issue on BP registerKoichi Shiraishi
BP should be callee-save. It will be saved automatically if there is nonzero frame size. $ go vet -framepointer ./pkg/atomicbitops pkg/atomicbitops/atomicbitops_amd64.s:27:1: frame pointer is clobbered before saving pkg/atomicbitops/atomicbitops_amd64.s:34:1: frame pointer is clobbered before saving pkg/atomicbitops/atomicbitops_amd64.s:50:1: frame pointer is clobbered before saving pkg/atomicbitops/atomicbitops_amd64.s:57:1: frame pointer is clobbered before saving pkg/atomicbitops/atomicbitops_amd64.s:64:1: frame pointer is clobbered before saving Signed-off-by: Koichi Shiraishi <zchee.io@gmail.com>

N.B. we don't explicitly support MIPS, but there's no reason it shouldn't work.

2020-03-30kvm: handle exit reasons even under EINTR.Adin Scannell
In the case of other signals (preemption), inject a normal bounce and defer the signal until the vCPU has been returned from guest mode. PiperOrigin-RevId: 303799678
2020-02-20Re-add atomicbitops_arm64.s to BUILD.gVisor bot
This was inadverently dropped by cl/295811743. PiperOrigin-RevId: 296254482
2020-02-18atomicbitops package cleanupsgVisor bot
- Redocument memory ordering from "no ordering" to "acquire-release". (No functional change: both LOCK WHATEVER on x86, and LDAXR/STLXR loops on ARM64, already have this property.) - Remove IncUnlessZeroInt32 and DecUnlessOneInt32, which were only faster than the equivalent loops using sync/atomic before the Go compiler inlined non-unsafe.Pointer atomics many releases ago.

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55
