=====XELK 2.x.y series=====
Practically speaking, for [[Axel_Embedded_Linux_Kit_(XELK)#XELK_software_components|XELK 12.x.y series]] this mechanism makes use of two different thresholds, denoted as <code>trip_point0</code> (also known as ''passive threshold'') and <code>trip_point1</code> (also known as ''critical threshold''. When Tj reaches <code>trip_point0</code>, Linux kernel scales down processor frequency:

System is too hot. GPU3D will work at 1/64 clock.
XELK 3.x.y kernels implement the same mechanism of XELK 2.x.y series. However a notable difference exists, that is default temperature thresholds depend on the silicon grade, as follows:
*for commercial parts
** passive thresholdsthreshold: 85°C** critical thresholdsthreshold: 90°C
*for extended commercial and industrial parts
** passive thresholdsthreshold: 95°C** critical thresholdsthreshold: 100°C
*for automotive parts
** passive thresholdsthreshold: 115°C** critical thresholdsthreshold: 120°C.
