Guest Nazgulled Posted July 15, 2010 Report Share Posted July 15, 2010 1) Compache is not enabled in stock kernel. In fact it's not even included. I patched the sources (it's not even in the vanilla kernel source tree v 2.6.29). I didn't know that, I though it was enabled... Can I assume that having compcache disabled, whatever it's doing, it's doing the same as the fault kernel right? Where can I read more about compcache and the default method used in the default kernel? I've searched but couldn't find much info about the two and differences between them. That's basically what I want to know, the differences and benefits of one versus the other... 2) The kernel should be ROM independent provided you merge it with the appropriate ramdisk to create the "right" boot.img Basically, I need to replace the ramdisk on my own boot.img with the one found on the boot.img from the download on this thread? And of course, use all the modules and init scripts... Right? Link to comment Share on other sites More sharing options...
Guest goatee Posted July 16, 2010 Report Share Posted July 16, 2010 This may seem like a stupid question, but without OC enabled, does this kernel provide better performance than the one included in r5? Link to comment Share on other sites More sharing options...
Guest davrian Posted July 17, 2010 Report Share Posted July 17, 2010 This may seem like a stupid question, but without OC enabled, does this kernel provide better performance than the one included in r5? I found the speed increase phenomenal, without overclocking... I have 100+ apps though and tend to multi task a fair bit. I enabled compcache to use my swap partition and i've not moved back since. It's nice to have ext4 support if you run a2sd as well! Link to comment Share on other sites More sharing options...
Guest goatee Posted July 19, 2010 Report Share Posted July 19, 2010 Thanks for the feedback - when touchpal is finished downloading and installing, I'll install it :angry:.

Guest NutsPT Posted July 19, 2010 Report Share Posted July 19, 2010 I'm using OverclockWidget and can't pass the 528Mhz even used several tutorials on this app/widget... :D set it to 691 but never updates... :\ Any help. Thx PS: I allready installed the zip :angry: Link to comment Share on other sites More sharing options...

Guest theFRAGGLE Posted July 21, 2010 Report Share Posted July 21, 2010 No OC but overall everything is smoother and more responsive. So, great, thank you. :angry: Link to comment Share on other sites More sharing options...
Guest vatvedt Posted July 21, 2010 Report Share Posted July 21, 2010 Trying out this one now, thanks! :angry: Seems good so far, but would be awesome with working overclocking up to 690MHz :D Link to comment Share on other sites More sharing options...
Guest DeekB Posted July 21, 2010 Report Share Posted July 21, 2010 Trying out this one now, thanks! :angry: Seems good so far, but would be awesome with working overclocking up to 690MHz :D I agree! Used this one for a couple of day's and was impressed compared to stock but like the OC feature. Link to comment Share on other sites More sharing options...
Guest vatvedt Posted July 22, 2010 Report Share Posted July 22, 2010 Is there any way to overclock this kernel to 691MHz? I'd love to overclock my Hero, and keep my R5 ROM :( Link to comment Share on other sites More sharing options...
Guest DeekB Posted July 23, 2010 Report Share Posted July 23, 2010 I went back to this kernal as the other ones as causing me issues, Would be good to get this overclocked though I agree with vatvedt Link to comment Share on other sites More sharing options...
Guest toxic-hero Posted July 23, 2010 Report Share Posted July 23, 2010 i don't want to OC my hero and also don't use a2sd. would teknologist kernel on hero make any difference for me? Link to comment Share on other sites More sharing options...
Guest venturerider Posted July 23, 2010 Report Share Posted July 23, 2010 i don't want to OC my hero and also don't use a2sd. would teknologist kernel on hero make any difference for me? Good question. Other than the added modules, are there any optimizations in the Teknologist kernel? Link to comment Share on other sites More sharing options...
Guest Posted July 26, 2010 Report Share Posted July 26, 2010 I'm reading a lot about some effect of compcache on the performance of heros using a2sd - can someone explain that to me? Also what benefit ext4 would bring? Link to comment Share on other sites More sharing options...

Also what benefit ext4 would bring? Compcache grabs a chuck of RAM and makes a compressed cache with it. The problem with that is that you already have a small amount of RAM. Now you have even less. So your OS will swap sooner and more often. Because the cache is compressed, that requires your CPU to compress/uncompress the pages as they are written/read from the cache. On a system with a slow CPU, that's not very good. So now, your OS is swapping more often and your CPU is compressing/decompressing on the fly. Therefore, when that cache kicks in, I expect the Hero will slow down. Of course, I might have completely misunderstood the way compcache works. If so, disregard this message ;-) Link to comment Share on other sites More sharing options...

Guest AlThePost Posted July 27, 2010 Report Share Posted July 27, 2010 i don't want to OC my hero and also don't use a2sd. would teknologist kernel on hero make any difference for me? I remember the 1.91 kernel making a huge difference over stock. I suggest a read of the support thread for it here as my understanding is that freeasabeer incorporated most (if not all) of the optimisations into this kernel. Sorry I can't be of more help. Btw, I'm not overclocking either (it doesn't appear to work correctly anyhow) but am using A2SD+ and my handset definitely 'feels' snappier in use with this kernel.

Guest arunshen Posted July 28, 2010 Report Share Posted July 28, 2010 Am using the kernel on MCR r5 with A2SD+ and it does feel more responsive. Link to comment Share on other sites More sharing options...
Guest heroboy Posted July 29, 2010 Report Share Posted July 29, 2010 i can confirm: no OC! within the OC settings it shows 691mhz but when u move the slider it goes only to max 528mhz. Overclocking doesn't work for me, too. :( I took a closer look at this and found, that there are only two powermanager governors compiled in tk kernel : ondemand (default setting) and performance. I tried to manipulate speeds via linux sys structure echo '691000' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed but sys interface seems not to react here. As far as I know, only userspace governor is capable of scaling cpu speed manually. Correct me, if I'm wrong. Maybe its worth a try to compile userspace governor with tk kernel ?

Maybe its worth a try to compile userspace governor with tk kernel ? no you dont need the userspace governor, because that governor just changes the frequencies and does not react to processor load or dynamically changes the cpu speed (which you absolutely want to save battery), just set the min and max freq using scaling_max_freq and scaling_min_freq and your done, the governor does the frequency switching for you.
