* crosvm: virtio-pmem deviceJakub Staron2019-06-05
| | | | | | | | | | | | | | | | | | | | Adds support for virtio-pmem device as an alternative for virtio-blk. Exposing disk image to guest as virtio-blk device results in both guest and host independently caching the disk I/O. Using virtio-pmem device allows to mount disk image as direct access (DAX) in the guest and thus bypass the guest cache. This will reduce memory foodprint of the VMs. BUG=None TEST=cargo test TEST=Boot patched termina kernel in crosvm; mount virtio-pmem device as DAX and run xfstests.

* Initial BIOS support.Cody Schuffelen2019-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The --bios argument is added as an alternative to the kernel positional argument. The BIOS runs in unreal mode (16-bit cs selector set to the end of 32-bit address space), which matches the default state KVM puts the segment and data registers into. Example usage: Build u-boot with "make qemu-x86_defconfig && make" Run crosvm with "crosvm_wrapper.sh run --bios=u-boot.rom" This produces the following message: """ U-Boot 2019.01-00017-gdc76aabe6a-dirty (May 21 2019 - 12:17:02 -0700) CPU: DRAM: 16 MiB unable to get online cpu number: -19 Warning: MP init failure Model: QEMU x86 (I440FX) Net: No ethernet found. error: can't find etc/table-loader Hit any key to stop autoboot: 0 => """ At this point the u-boot shell works with stdin/stdout, but virtual disks passed with --rwdisk weren't immediately visible from running "virtio scan" and "virtio info".

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.

* sync: Mutex type with methods that panic instead of return errorDavid Tolnay2018-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL adds a crate `sync` containing a type sync::Mutex which wraps the standard library Mutex and mirrors the same methods, except that they panic where the standard library would return a PoisonError. This API codifies our error handling strategy around poisoned mutexes in crosvm. - Crosvm releases are built with panic=abort so poisoning never occurs. A panic while a mutex is held (or ever) takes down the entire process. Thus we would like for code not to have to consider the possibility of poison. - We could ask developers to always write `.lock().unwrap()` on a standard library mutex. However, we would like to stigmatize the use of unwrap. It is confusing to permit unwrap but only on mutex lock results. During code review it may not always be obvious whether a particular unwrap is unwrapping a mutex lock result or a different error that should be handled in a more principled way. Developers should feel free to use sync::Mutex anywhere in crosvm that they would otherwise be using std::sync::Mutex.
