virtio_pcie

Description

Virtio PCIE File System device based on the Virtio 1.2 specification. Implements the base functionality. Does not implement:

VIRTIO_FS_F_NOTIFICATION

This device uses MSI-X for interrupts, and does currently not support legacy interrupts. CONFIG_PCI_MSI=y must thus be set in the kernel config.

Interfaces Implemented

conf_object, log_object, pcie_device

Connects

clkreq (optional): Required interfaces: signal
upstream_target (optional): Required interfaces: pcie_map; Optional interfaces: io_memory, memory_space, pcie_link_control, port_space, ram, rom, transaction, transaction_translator, translator

Notifiers

cell-change: Notifier that is triggered after the object's cell was changed.
object-delete: Notifier that is triggered just before Simics object is deleted.
queue-change: Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.
state-change: Notifier on potential DML state change

Commands for this class

info – print information about the object
status – print status of the object

Attributes

always_cache: Pseudo attribute; read/write access; type: b
Enable full caching for FUSE, which increases the performance of the virtioFS mount point on the guest. NOTE! Only set to true if no modifications will be done in the shared directory from the host until the simics process has been terminated. Doing so might result in data loss. Disabled by default
clkreq: Optional attribute; read/write access; type: o|[os]|n
CLKREQ output signal (active high)
Required interface: signal
daemon_log_file: Pseudo attribute; read/write access; type: s|n
Enable logs for the FUSE daemon and specify the output file for the logs
share: Pseudo attribute; read/write access; type: s|n
Directory on the host to share with the simulated target or unix domain socket file created by virtiofs daemon
tag_name: Optional attribute; read/write access; type: s
The tag name to be used when mounting the device on the guest
