* Add runnable vcpuDylan Reid2019-12-10
| | | | | | | | | | | | | Add a new type `RunnableVcpu` for a vcpu that is bound to a thread. This adds type safety to ensure that vcpus are only ever run on one thread because RunnableVcpu can't `Send`. It also ensures multiple vcpus can't run on the same thread.

* use `SharedMemory::{named, anon}` to replace `::new`Zach Reizner2019-09-11
| | | | | | | | | | | | | | | | The new constructors are shorter and omit the bare `None` in the `anon` call sites which gave no clues to the reader what the effect of that `None` was. This should improve readability.

* edition: Remove extern crate linesDavid Tolnay2019-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Rust 2018 edition, `extern crate` is no longer required for importing from other crates. Instead of writing: extern crate dep; use dep::Thing; we write: use dep::Thing; In this approach, macros are imported individually from the declaring crate rather than through #[macro_use]. Before: #[macro_use] extern crate sys_util; After: use sys_util::{debug, error}; The only place that `extern crate` continues to be required is in importing the compiler's proc_macro API into a procedural macro crate. This will hopefully be fixed in a future Rust release. extern crate proc_macro; TEST=cargo check TEST=cargo check --all-features TEST=cargo check --target aarch64-unknown-linux-gnu TEST=local kokoro Change-Id: I0b43768c0d81f2a250b1959fb97ba35cbac56293 Reviewed-on: https://chromium-review.googlesource.com/1565302 Commit-Ready: David Tolnay <dtolnay@chromium.org> Commit-Ready: ChromeOS CL Exonerator Bot <chromiumos-cl-exonerator@appspot.gserviceaccount.com> Tested-by: David Tolnay <dtolnay@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: David Tolnay <dtolnay@chromium.org>
* toolchain: Update to Rust 1.31.0David Tolnay2018-12-13
| | | | | | | | | | | | | | | | | | We updated the production toolchain from 1.30 to 1.31 in CL:1366446. This CL does the same upgrade for the local developer toolchain and Kokoro. The relevant changes are in rust-toolchain and kokoro/Dockerfile. The rest are from rustfmt.

* kvm: support adding read only memory to VMsZach Reizner2018-02-06
| | | | | | | | | | | | | | | | | Read only memory is useful for triggering VM exits when the VM writes to memory while allowing reads transparently and quickly. For example, a virtual device implementation might not care if the VM reads a memory mapped device register, but a exit would be required if the VM wrote to the same register.
