This test boots a Linux kernel, and checks that the given command
|
|
|
357786 |
line was effective in two ways:
|
|
|
357786 |
|
|
|
357786 |
* It makes the kernel use the set "console device" as a console
|
|
|
357786 |
* The kernel records the command line as expected in the console
|
|
|
357786 |
|
|
|
357786 |
Given that way too many error conditions may occur, and detecting the
|
|
|
357786 |
kernel boot progress status may not be trivial, this test relies on a
|
|
|
357786 |
timeout to handle unexpected situations. Also, it's *not* tagged as a
|
|
|
357786 |
quick test for obvious reasons.
|
|
|
357786 |
|
|
|
357786 |
It may be useful, while interactively running/debugging this test, or
|
|
|
357786 |
tests similar to this one, to show some of the logging channels.
|
|
|
357786 |
Example:
|
|
|
357786 |
|
|
|
357786 |
$ avocado --show=QMP,console run boot_linux_console.py
