Cannot disable HAL device polling
Last modified: 2013-06-20 08:10:42 EDT
Description of problem:
No way for user to disable device polling other than editing system files
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Research how to prevent HAL from polling my unused CD-ROM driver
2. Note references to utility "hal-disable-polling" which is not included in the
3. End up editing /usr/share/hal/fdi/policy/10osvendor/20-storage-methods.fdi to
Must edit system file to disable HAL's device polling.
There should be a way other than editing system files to disable HAL's device
I only use my CD-ROM drive once every ~2 years, to upgrade the operating system.
So why do I have to live with the high-frequency polling of the drive every
minute of every day? This polling is consuming precious CPU and bus bandwidth
(at a rate of 37260 interrupts per hour) and providing nothing I want in return.
Please provide a method if disabling device polling. I've edited the system
file as noted above but that change will be lost on the next update of the HAL
RPM. I don't care if the solution is providing the "hal-disable-polling"
utility or some sort of /etc/sysconfig/haldaemon hack to the init script.
You can simply drop an fdi in /etc/hal/fdi - that's why it's there (to allow
sysadmins to override policy). To make this even easier use the
# cat /etc/hal/fdi/information/media-check-disable-DVD_GCC4244.fdi
<?xml version="1.0" encoding="UTF-8"?>
<merge key="storage.media_check_enabled" type="bool">false</merge>
If haldaemon is not install then how do i disable polling?
I am running on RHEL 5.5 64 bit.
I want to disable polling for tape.
