Re: cpu reclocking to 500Mhz, overclocking to 533Mhz, performance tests and bootloader images
Thanks a lot! I have done some testing again, this time with Qi: the default QtMoko kernel (2.6.29-rc3) gives an error/kernel panic when booting with the (*any*) overclocked Qi, while the SHR-U kernel (2.6.32) *does* boot. I haven't tested SHR-U any further, but if you're saying it suspends and resumes fine, I believe you :-) I get nothing but a black screen and flashing AUX button with the QtMoko kernel, while the SHR-U kernel boots fine. So there is quite a difference in kernel config, or maybe even kernel version. I hope someone can find out what kernel config (or bootloader adjustments) is needed for the overclock to be successful (both under u-boot and Qi), because this still is very promising! Especially the different CPU voltages are very nice to experiment with, that should give a good balance between speed, heat and power consumption.

2010/7/4 Tha_Man jeroenb...@hotmail.com Hi again, I couldn't resist to do some more testing, so I copied my QtMoko SDcard installation to NAND. QtMoko from NAND boots fine in most cases (see overview), it's suspend and resume that fails when overclocked. However, suspend and resume works fine with the original NAND U-boot and your default clocked U-boot. I've flashed the overclocked images exactly as you posted and flashed u-boot_env.in as well, no errors were reported during flashing. Here's an overview: Tested under QtMoko v24, using different u-boot images flashed in NAND: + u-boot-gta02v5-1.3.1: works fine + u-boot.udfu_400_100_1.7: works fine - u-boot.udfu_450_112_1.65_1.9: won't boot (hangs on 'Starting kernel...') - u-boot.udfu_450_112_1.7_1.9_sdmax: won't boot (hangs on 'Starting kernel...') * u-boot.udfu_500_83_1.7: fails to resume after suspend * u-boot.udfu_500_83_1.7_1.8_CLK2: fails to resume after suspend * u-boot.udfu_533_88_1.7: fails to resume after suspend * u-boot.udfu_533_88_1.7_1.8_CLK2: fails to resume after suspend So most u-boot images boot fine with QtMoko v24 and report the correct speeds, but my phone doesn't wake up after suspend with any of the overclocked images; I have to remove the battery to be able to boot again. Even the 450Mhz-images you reported as 'working under qtmoko' fail with me, but I'm not sure if you tested suspend and resume. I'm using the default v24-kernel, based on 2.6.29 I believe. I hope my tests are of any help, if I need to test something else, please let me know.

Re: cpu reclocking to 500Mhz, overclocking to 533Mhz, performance tests and bootloader images
Hi, Gennady suggested the same thing, but the 450Mhz-settings fail on kernel start (see my previous message, I haven't tried the 465 settings). These settings need a recompiled kernel according to Gennady's first message, did you recompile your kernel? If not, I'm very curious why it doesn't work for me! I'm assuming you're running QtMoko v24 as well, either from SD or NAND.

Re: cpu reclocking to 500Mhz, overclocking to 533Mhz, performance tests and bootloader images
Thanks a lot for the clarification! I successfully flashed my Freerunner with u-boot.udfu_533_88_1.7_1.8_CLK2 and got the following results (from QtMoko/Debian): neo:~# dmesg | grep -i mhz [0.00] S3C244X: core 532.000 MHz, memory 88.666 MHz, peripheral 44.333 MHz neo:~# cat /proc/cpuinfo Processor : ARM920T rev 0 (v4l) BogoMIPS: 265.42 Features: swp half thumb CPU implementer : 0x41 CPU architecture: 4T CPU variant : 0x1 CPU part: 0x920 CPU revision: 0 Hardware: GTA02 Revision: 24420360 Compared to the original clocks: neo:~# dmesg | grep -i mhz [0.00] S3C244X: core 400.000 MHz, memory 100.000 MHz, peripheral 50.000 MHz neo:~# cat /proc/cpuinfo Processor : ARM920T rev 0 (v4l) BogoMIPS: 199.47 Features: swp half thumb CPU implementer : 0x41 CPU architecture: 4T CPU variant : 0x1 CPU part: 0x920 CPU revision: 0 Hardware: GTA02 Revision: 24420360 -- So basically from 200 bogoMIPS at 400Mhz to 265 bogoMIPS at 533Mhz, very nice! The QtMoko interface seemed even more responsive, I was able to operate my phone normally and start Navit for example. However, QtMoko seems to have a problem with booting from u-boot using an SD card and suspending. I tried both with *and* without the overclock, but when I suspend my phone when I booted from u-boot, it won't resume... I'm using a QtMoko installation on my SD card, I haven't tried QtMoko on NAND-flash yet (can anyone confirm it should work?). This is obviously a QtMoko problem and not related to the overclock, but still I am curious: is it possible to achieve the overclock when booting with Qi, by setting kernel parameters or something? Thanks for your efforts and I hope others will test it as well!

This is seriously cool! Great to see an overview at different speeds, have you been able to test for stability over a few days of normal operation? If I understand correctly, I will need to patch/recompile my kernel besides flashing a new Uboot. Is this is easy to do for kernels of popular distro's, such as SHR and QtMoko?
