* devices: port vhost-user-net from cloud-hypervisorAlyssa Ross2021-05-11
| | | | | | | This is the cloud-hypervisor vhost-user-net code, modified just enough to compile as part of crosvm. There is currently no way to run crosvm with a vhost-user-net device, and even if there were, it wouldn't work without some further fixes.
* devices: implement dedicated Interrupt struct for virtio WorkerZide Chen2019-10-25
| | | | | | | | | | | | | | | | | | | | | | The code to inject interrupt to the guest can be generic to all virtio devices. This patch: - move those guest interrupt related fields out of Worker structure and put in a separate file, making the worker code cleaner. - remove redandant functions across virtio devices: signal_used_queue(), signal_config_changed(), etc. BUG=chromium:854765 TEST=sanity test on eve and Linux TEST=cargo test -p devices Change-Id: I8e9f760f2057f192fdc74d16a59fea2e6b08c194 Signed-off-by: Zide Chen <zide.chen@intel.corp-partner.google.com> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/1869553 Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> Tested-by: Daniel Verkamp <dverkamp@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Daniel Verkamp <dverkamp@chromium.org>
* devices: virtio: add copy_config() helper functionDaniel Verkamp2019-08-16
| | | | | | | | | | | | | | | | | | | | | | | Add a new virtio configuration copying function to replace all of the slightly varying read_config() and write_config() implementations in our virtio devices. This replaces a lot of tricky bounds-checking code with a single central implementation, simplifying the devices to a single call to copy_config() in most cases. The balloon device is also changed to represent its config space as a DataInit struct to match most other devices and remove several unwrap() calls.

* crosvm: Implement Reader/Writer interface over DescriptorChain.Jakub Staron2019-06-21
| | | | | | | | | | | | | | | | | | | This change adds a convinient interface over DescriptorChain. It hides the complexity of DescriptorChain and allows to treat it as a pair of read-only and write-only buffers. In the future, it will also allow to easily support indirect descriptors.

* 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.

* Adds Virtio-Input device simulationJorge E. Moreira2019-02-01
| | | | | | | | | | | | | | | | | | | | | | | | This allows decoupling input from the wayland socket while using a standard virtio device for it. The proposed virtio input spec can be found at https://www.kraxel.org/virtio/virtio-v1.0-cs03-virtio-input.pdf, it has already been implemented in qemu and (guest) kernel support exists since version 4.1. This change adds the following options to crosvm: --evdev: Grabs a host device and passes it through to the guest --<device>: Creates a default configuration for <device>, receives the input events from a unix socket. <device> can be 'keyboard', 'mouse' or 'trackpad'.

* crosvm: add debug labels to devices for improved SIGCHLD logsZach Reizner2019-01-26
| | | | | | | | | | | | | | | | | | | Each device (Bus, Pci, Proxy, etc), gets a debug label associated with it. When a child is spawned, the debug label for it is stored in a map with the child's pid as the key. If a SIGCHLD is handled, this map is used to print a more helpful message about exactly which child died. BUG=None TEST=run with sandboxing and a faulty child device check logs for message about child died the child should have a debug label Change-Id: I61fbbee0a8e701249533a7a3a6a1ad48840f12e5 Reviewed-on: https://chromium-review.googlesource.com/1432835 Commit-Ready: Chih-Yang Hsia <paulhsia@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Tested-by: Zach Reizner <zachr@chromium.org> Reviewed-by: Daniel Verkamp <dverkamp@chromium.org>
