The applesmc module allows to monitor the temperature on Macmini terminals and set/get the fan speed in order to control the temperature. |
|||
The rpm available at Bashlinux repository includes the kernel module for CentOS and a service daemon which is monitoring the temperature and setting the fan speed. |
|||
To get the module working install the rpm from repository: |
|||
<pre><nowiki> |
|||
# yum -y install applesmc-utils |
|||
</nowiki></pre> |
|||
== drm == |
|||
The drm module avilable at Bashlinux repo has been modified in order to create dri device for AGP card on CX700M2 chipset. |
|||
== tpm == |
|||
The tpm module available at Bashlinux has been build from sources to setup the TPM chipset on Dell servers. |
|||
To build the module is necessary to enable it on kernel, one way to get this done is going to the kernel source folder, usually `/usr/src/linux` then run the config utility. |
|||
'''Useful Information''' |
|||
Please note that `ncurses-devel` must be installed to get menuconfig running. |
|||
<pre><nowiki> |
|||
# cd /usr/local/src |
|||
# make menuconfig |
|||
</nowiki></pre> |
|||
Select the TPM device driver under _Device Drivers > Character devices > TPM devices_, save the configuration and build the kernel modules. |
|||
<pre><nowiki> |
|||
# make modules |
|||
</nowiki></pre> |
|||
== usblp == |
