| === API documentation generation ===
| |
|
| |
| '''Summary:''' Generation of API documentation from doc comments
| |
|
| |
| QEMU currently has many functions documented using the GTK-Doc
| |
| syntax, but there is no mechanism to actually generate API
| |
| documentation from these doc comments. We need build rules
| |
| that generate API documentation from C and Python source code.
| |
|
| |
| Tasks:
| |
| * Picking a documentation generation tool (unclear if we should stay with GTK-Doc)
| |
| * Fixing or converting existing documentation comments
| |
| * Writing build rules to generate the documentation
| |
| * Extra tasks, if time allows:
| |
| ** Improving clarity or formatting of existing doc comments
| |
| ** Converting existing ad-hoc comments in the code to doc comment syntax
| |
| ** Add doc comments to existing APIs that are undocumented
| |

| === Guest ABI automated testing ===
| |
|
| |
| '''Summary:''' Automated test of Guest ABI and compatibility
| |
|
| |
| QEMU tries to provide a stable '''guest ABI''' on versioned
| |
| machine-types. Despite investing lots of effort keeping
| |
| compatibility, we have no automated testing to detect common
| |
| mistakes that break guest ABI. It should be possible to write
| |
| automated test cases that will compare a virtual machine to a
| |
| previously stored dump of guest ABI information.
| |
|
| |
| A guest ABI dump may include, for example:
| |
|
| |
| * Data returned by CPUID instruction (or equivalent)
| |
| * Physical memory and I/O port maps
| |
| * Device addresses (PCI, USB, etc.)
| |
| * Device IDs and other guest-visible device fields
| |
| * Value of QOM properties that affect device behavior
| |
|
| |
| This might require improving or adding new QMP commands to provide information to be validated by the automated test cases. Some test cases may use a custom kernel image for collecting guest-visible data, or extending the qtest protocol.
