| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* arch: add virtio-pci eventfds with exact matchDaniel Verkamp2018-10-11
| | | | | | | | | | | | | | | | | | | | The virtio PCI spec (4.1.5.2 Notifying The Device) says: "The driver notifies the device by writing the 16-bit virtqueue index of this virtqueue to the Queue Notify address." We were previously registering the notify address specifying NoDatamatch; switch this to a 16-bit match of the queue index to follow the specification.

* sys_util: remove Scm struct and sock_ctrl_msg C libraryZach Reizner2018-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Scm object was made to reduce the number of heap allocations in the hot paths of poll loops, at the cost of some code complexity. As it turns out, the number of file descriptors being sent or received is usually just one or limited to a fixed amount that can easily be covered with a fixed size stack allocated buffer. This change implements that solution, with heap allocation as a backup in the rare case that many file descriptors must be sent or received. This change also moves the msg and cmsg manipulation code out of C and into pure Rust. The move was necessary to allocate the correct amount of buffer space at compile time. It also improves safety by reducing the scope of unsafe code. Deleting the code for building the C library is also a nice bonus. Finally, the removal of the commonly used Scm struct required transitioning existing usage to the ScmSocket trait based methods. This includes all those changes.

* Arch: Big refactor and add an empty PCI busDylan Reid2018-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting up IO, accept an optional PciRoot device to put on the IO bus. For aarch64, it's currently ignored. For x86_64, it will be added at 0xcf8. break up mmio device creation and registration Moving forward registration will be handled by the architecture specific code. However, creation will be handled by the common code. To make that easier split up the two steps so a list of devices is created, then each is registered later. Start moving to a model where the configuration generates a set of components that are passed to the architecture. The architecture will crate a VM from the components. Break up the big run_config function and move architecture specific parts to the various architectures. This doesn't refactor the function calls each architecture makes, but moves the setup flow in to the arch impls so that they can diverge in the future.

* x86_64: fill cache info in cpuid, stop spoofing CPU vendor idSlava Malyugin2018-07-09
| | | | | | | | | | | | | | | | | | | | | | | | | The fix passes through cache-related CPU entries 2, 4, 0x80000005 and 0x80000006 similar to how QEMU does it. Note passing this cpuid info itself is not sufficient unless CPU vendor is something Linux kernel recognizes. Therefore, I am removing cute spoofing of the vendor id, allowing host value to pass through. I believe it is generally a bad idea to spoof vendor id as lots of kernel and user space code gets confused and may take unoptimized paths. The corollary is that removing the spoofing may have unintended consequences correctness- and performance-wise. I would appreciate recommendation on additional testing.
