* devices: virtio: Initial implementation of virtio-video deviceKeiichi Watanabe2020-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | This CL adds a fundamental part of the virtio video device, which will be shared between the encoder and the decoder. Both devices uses the virtio-video protocol proposed as RFC v3 [1,2]. The corresponding driver code is at CL:2060327 and its children CLs. The actual decoding and encoding logic will be implemented in different CLs.

* Adding hypervisor crate to abstract out Kvm implementationUdam Saini2020-05-03
| | | | | | | | | | | | | | | | | | | | | | This is a separate hypervisor crate for interacting with Kvm in an abstract manner. The intention is to not leak the internals of kvm with its specific calls in various places in the codebase. Currently, this just creates an initial structure for adding various implementations over time. In addition, a SafeDescriptor class is added, that wraps a raw file descriptor safely, without needing to wrap it in the rust file class. The intention is to use this for non file raw descriptors.

* virtio-gpu: gfxstream backendLingfeng Yang2020-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new backend type, gfxstream, that calls out to a C library implementing the actual rendering. The purpose is to allow the Cuttlefish and Android Studio Emulator teams to use crosvm with the current API-forwarding style of rendering employed in the Android Studio Emulator. Also, introduces a new key to the --gpu command line interface, backend=, which selects from different backends. Note that the previous behavior is now deprecated and will be removed after some time (when all clients switch over to backend=). The gfxstream backend itself implements a subset of 3d-related resource and context creation/transfer/execbuffer commands. Their meaning is specific to the way in which they are interpreted in the backend library. To interface with display, gfx stream backend takes a callback that is run on guest vsync. The callback is responsible for repainting the display's contents. gfx stream provides a callback, get_pixels, that can be used asynchronously. The asyncness is not taken advantage of currently but will be useful for cases where the client attached to the VMM might want to update at a different rate than guest vsync. The guts of the stream backend library is currently defined here: https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android-qemu2-glue/emulation/virtio-goldfish-pipe.cpp The linking of the library is controlled via the feature "gfxstream". If the feature is turned off, we use a default do-nothing stub impl.

* Support composite disks.Cody Schuffelen2019-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new disk file type next to raw files and qcow images that represent an indirection to further raw disk files. The disk file itself is a proto file with references to file paths for other disks to open and their virtual offsets and lengths. The intention is to make it easy to assemble a single virtual hard disk out of several distinct partition files. In the particular case of Cuttlefish running Android in a VM, this is relevant as the Android build system distributes partitions as separate raw files. While the simple solution is to pass each partition as a separate raw disk, some functionality (like the bootloader) assumes there is a partition table with multiple distinct partitions on a single disk. Implementing composite disk support in the VMM bridges this gap through supporting the general-purpose case of a disk built out of multiple component files. If desired, this can be extended to support qcow files to support unusual configurations like a mixed qcow/raw disk. Enabled with the "composite-disk" feature.

* split crosvm into a library and a main "crosvm" binaryZach Reizner2019-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change has 3 parts: - Modify the Cargo.toml to point at the bin and the lib source. - Move modules and Config struct into the lib source - Fix the argument/plugins module's doc comments which had never been tested. The motivation for this change is to make testing crosvm's major functionality (booting guest kernels, emulating hardware, etc) easier to do from a cargo test. Being able to launce a crosvm config via the API instead of the binary's command line will be possible with this change. A side benefit is that this also enables doc tests in the lib side of crosvm. The doc tests in binaries are not run due to a limitation in how they get tested by cargo.

Underaligned references of type &T or &mut T are always undefined behavior in Rust. - Same pattern in x86_64. - Same pattern in plugin::vcpu. - Code in crosvm_plugin that dereferences a potentially underaligned pointer.

* devices: Add an Ac97 PCI deviceDylan Reid2019-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ac97 device provides the guest with an audio playback device. All input devices are stubbed out. Only playback at 48kHz is supported. The device is emulated by `Ac97Dev` which interfaces with the PCI bus. `Ac97Dev` uses `Ac97` to drive audio functions and emulate the device registers. Physical Ac97 devices consist of two parts, the bus master and a mixer. These two sets of registers are emulated by the `Ac97BusMaster` and `Ac97Mixer` structures. `Ac97BusMaster` handles audio samples and uses `Ac97Mixer` to determine the configuration of the audio backend.

* 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.
