Hey Roman, maybe you and da-g can get together to get the gpu tweaks and 54mhz minimum implemented into jugs

GPU tweaks don't really do much on these chipsets. It's not really worth the extra voltage you throw at it.
Ok. It sounded good though lol. Thanks for the info

Depends on the test - most of them can't push stock settings - But the "Monjori Shader Benchmark" from market shows 43 fps @ stock 266MHz max GPU and 51 fps @ 300MHz OC 
Real world, you are probably right.. but the GPU also scales so provided the proper speed steppings it won't park up at the highest speed unless it needs to

Why have you stop the development for this kernel???
I find indersting the thing that kernel get at 1.89 mhz.

Will this kernel ever get boot animation support???? Would be nice!

Yeah. A lot. This will not work on ICS.
Guess I'll bump this to. Um, you do see how old this thread is? There was no ICS for the T989 when this was made. Short answer, this is a GB kernel,not an ICS kernel.

Jugs!

What the hell this is
- OC up to 1.836 ghz
- should boot into stock frequencies
- added BFQ I/O scheduler and made default
- patched drivers from newer Telus 989D source
- BLN
- added zram
- working init.d support
- insecure
- and much much more. Check the latest additions in the change log!
Change Log
Code:[B][U]0.3 - Nov 6[/U][/B] - added BLN! (use neldar's BLN control app from the market) - tweaked ondemand gov - added 1.89ghz step - any weirdness going past 1.72 should be fixed - added snapdragon compiler flag optimizations [B][U]0.2 - Nov 4[/U][/B] - added zram (must enable through init script, more on it below) - ALSO LOL WE DONT NEED THIS WE HAVE 999999MB OF RAM - patched drivers from Telus 989D source (newer, less debugging) - increased voltages to more stock-like values (uv by yourself) - boots up into stock frequencies (384 - 1512) (oc by yourself) 0.1 - Nov 3 - initial release
Bugs
Right now, there doesn't seem to be any bugs. However, if you do get a random reboot, or are having boot loops please provide me with a log and follow the instructions.
- Flash kernel (make sure you've wiped cache & dalvik cache)
- After it bootloops/freezes, immediately boot into recovery (unplug usb, hold power, vol +/vol -, let go of power when you see Samsung logo)
-
Code:
adb pull /proc/last_kmsg - upload that last_kmsg for me (please don't post it, it can get long!)
Voltage Control
You can control it via shell/init.d scripts as follows
[ to over volt ALL frequencies by 25000 uv (microvolts) ]
[ to under volt ALL frequencies by 25000 uv (microvolts) ]Code:echo "+25000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
Code:echo "-25000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
[ to set a specific frequency (ie 1.18 GHz) with a specific voltage (ie 1.0875 volts) ]
Code:echo "1188000 1087500" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
Clock Control
Just about any OC app will work just fine. By default, the kernel sets the max frequency to the highest frequency available. You can change this by adding a few lines to an init.d script (or run commands in a shell).
For instance, setting stock freqs would look like this
Code:(su if in shell) echo 384000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq echo 1512000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq echo 1 > /sys/devices/system/cpu/cpu1/cpufreq/online echo 384000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq echo 1512000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
zRam
To enable zRam you must execute the following commands in shell as root
Code:mkswap /dev/block/zram0 swapon /dev/block/zram0
This needs to be run on every reboot.
You can check to see if it's enabled/actually being used:
Code:$ free total used free shared buffers Mem: 801980 664364 137616 0 50656 -/+ buffers: 613708 188272 Swap: 98300 0 98300
free = 0? it's not being used. usually takes a while to build up (especially with the megashittons of RAM we have)
Misc
- Make sure you know how to get into recovery via HARDWARE KEY COMBO - I HAVE WARNED YOU
- Please do not include this with any ROMs
- Source available on my github (link in sig)
- You can use the kernel with any ROM out currently.

Please STOP spewing crap and non-sense about kernels.
mfreq is used to FORCE MAX FREQUENCY for CPU governors and has ABSOLUTELY NOTHING to do with min frequency adjustments. It is set to root write only as protection against accident overrides from user space binaries.
here's the code snippet from cpufreq from the kernel:
Code:static ssize_t store_mfreq(struct sysdev_class *class, struct sysdev_class_attribute *attr, const char *buf, size_t count) { u64 val; if (strict_strtoull(buf, 0, &val) < 0) { pr_err("Invalid parameter to mfreq\n"); return 0; } if (val) override_cpu = 1; else override_cpu = 0; return count; } static int set_cpu_freq(struct cpufreq_policy *policy, unsigned int new_freq) { int ret = 0; struct cpufreq_freqs freqs; freqs.old = policy->cur; if ([COLOR="Red"]override_cpu[/COLOR]) { [COLOR="Red"]if (policy->cur == policy->max)[/COLOR] return 0; else [COLOR="red"]freqs.new = policy->max;[/COLOR]6
Can you please refrain from posting ****, atleast in my thread, that you can't backup with proof or actual knowledge.
Thanks.
