hi,
thanks for the reply, though it will be some time before i try this out
and can let you know the result.
the reason why i would like to downgrade is because i'm trying to perform
some frequency scaling experiments. v0.4 seems to have better support in
this regard with "/proc/scale". in v0.5 there is a
"/proc/cpu/clock/current" file though. however the latter seems to support
only 3 freqs viz. 176900, 191700, 206400. anything outside this and the
ipaq freezes and for expts this range is not good enough. in v0.4 there
seems to be promise of 11 different freqs from 59Mhz to 206Mhz and i
have heard from people that they have been successfull in switching
across these freqs. so i want to check on this. any help in this
regard would be appreciated. i'm using a 3650 model.
also surprised to see a package for an older version floating in the v0.5
archives ( cpu_scale, useless without /proc/scale functionality). the same
seems to exist in v0.6, but with a note. apart from the note, does it work
in v0.6? anybody tried it? when x starts it seems to try to change some
frequencies. why?
frequency scaling, does anyone had any success? any pointers?
