qgraph API for the qtest driver framework
This series of patches introduce a different qtest driver
organization, viewing machines, drivers and tests as node in a
graph, each having one or multiple edges relations.
The idea is to have a framework where each test asks for a specific
driver, and the framework takes care of allocating the proper devices
required and passing the correct command line arguments to QEMU.
A node can be of four types:
- MACHINE: for example "arm/raspi2"
- DRIVER: for example "generic-sdhci"
- INTERFACE: for example "sdhci" (interface for all "-sdhci" drivers)
- TEST: for example "sdhci-test", consumes an interface and tests
the functions provided
An edge relation between two nodes (drivers or machines) X and Y can be:
- X CONSUMES Y: Y can be plugged into X
- X PRODUCES Y: X provides the interface Y
- X CONTAINS Y: Y is part of X component
Basic framework steps are the following:
- All nodes and edges are created in their respective machine/driver/test files
- The framework starts QEMU and asks for a list of available drivers
and machines
- The framework walks the graph starting from the available machines and
performs a Depth First Search for tests
- Once a test is found, the path is walked again and all drivers are
allocated accordingly and the final interface is passed to the test
- The test is executed
- Unused objects are cleaned and the path discovery is continued
Depending on the QEMU binary used, only some drivers/machines will be available
and only test that are reached by them will be executed.
This work is being done as Google Summer of Code 2018 project for QEMU,
my mentors are Paolo Bonzini and Laurent Vivier.
