Software-Emulated XIR
A software-emulated External Initiated Reset (XIR) has been added to the Sun Blade
2000 workstation.
By default, the XIR feature is activated by pressing the power switch three times
within 1.5 seconds. When this is done, the Sun Blade 2000 system changes to the ok
prompt. This allows you to begin troubleshooting procedures immediately upon first
failure, improving time to resolution.
Note – XIR causes a hard break, similar to the Stop-A key command, and an
immediate change to the ok prompt. The file system is not synchronized and
services are not systematically shut down. Therefore, XIR should be used only when
there is no other way to drop to the ok prompt (for example, when the system has
"hung").
To make the software-emulated XIR possible, the todds1287 driver has been
modified to generate a level-15 interrupt whenever the power switch is pressed.
Additionally, the driver makes a time interpretation of switch presses and executes
the XIR according to the properties set in the /etc/system file.
