Message-ID: <E19uTo2-0005dc-LD@flint.arm.linux.org.uk> (raw)
Update of /mnt/src/cvsroot/cpufreq
In directory flint:/tmp/cvs-serv21659
Modified Files:
patch
Log Message:
* add speedstep-smi driver (Hiroshi Miura)
* clean up speedstep-smi driver (Dominik Brodowski)
- fixes a couple of warnings
- to run as a module, we need to export ist_info. Also, only show the
IST_INFO line in dmesg if speedstep_smi is enabled.
- Use a new ->resume callback in the cpufreq core.
- let's call this driver "speedstep-smi" in cpufreq_driver also
- if the smi_get_freqs call fails, fall back to the "let's try it out
and see what frequency we are at" mechanism. Needed on my notebook (at
least).
* update driver/cpufreq/cpufreq.c
