Top speed reduced

[blackinjun]

Did anyone notice before .26 that the top unused speeds in cpu spy were 1.9 and the top speed now is 1.7??

It now reads the correct speed:

Yes, there's been some changes in the DVFS tables (tegra3_dvfs.c) in the newer kernel:

.22:

CPU_DVFS("cpu_g",  5, 3, MHZ,   1,   1, 770, 770,  910,  910, 1150, 1230, 1280, 1330, 1370, 1400, 1470, 1500, 1500, 1540, 1540, 1700,1810,1900),
CPU_DVFS("cpu_g",  5, 4, MHZ,   1,   1, 770, 770,  940,  940, 1160, 1240, 1280, 1360, 1390, 1470, 1500, 1520, 1520, 1590, 1700, 1700,1810,1900),

.26:

CPU_DVFS("cpu_g",  5, 3, MHZ,   1,   1, 770, 770,  910,  910, 1150, 1230, 1280, 1330, 1370, 1400, 1470, 1500, 1500, 1540, 1540, 1700),
CPU_DVFS("cpu_g",  5, 4, MHZ,   1,   1, 770, 770,  940,  940, 1160, 1240, 1280, 1360, 1390, 1470, 1500, 1520, 1520, 1590, 1700),

As you can see they've removed 1810 and 1900 MHz from the dynamic frequency range. Probably because it wasn't supposed to be there?

T33 can be overclocked to 1900, but on the stock kernel couldn't and can't go beyond 1700 for single-core and 1600 for multi-core use, so now it just shows what was actually happening already.

Correct. those higher speeds were only for testing purposes. now if you were rooted and still on older firmware, you couldve manually overclocked those higher speeds.

Isn't this the same thing we ran into with the Prime. The higher speeds were listed but not accessible and we surmised they were saving them for the next model.
