Module Name: src
Committed By: macallan
Date: Thu May 14 01:10:19 UTC 2009
Modified Files:
src/sys/arch/sgimips/hpc: files.hpc hpc.c
Added Files:
src/sys/arch/sgimips/hpc: panel.c
Log Message:
add a driver for the Indy's front panel buttons.
- power button presses are reported to sysmon
- volume control buttons are reported to PMF
TODO: add better key repeat code. The hardware keeps firing interrupts at us
whenever a button is down and not on - say - status change. If we don't clear
the interrupt we'll be fired on until someone clears it. We should probably
disable the entire interrupt and occasionally poll for button release.
