Hello,
these patches implement support for setting the rate of the EMC clock based on stats collected from the ACTMON, a piece of hw in the Tegra124 that counts memory accesses (among others).
It depends on the following in-flight patches:
* MC driver: http://thread.gmane.org/gmane.linux.ports.tegra/19623 * EMC driver: http://thread.gmane.org/gmane.linux.ports.arm.kernel/365125 * CPUFreq driver: http://thread.gmane.org/gmane.linux.kernel/1812962
I have pushed a branch here for testing:
http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=actmon
Regards,
Tomeu
