Welcome to the machinex wiki! Really just a space for older changelogs. Older Updates: UPDATES - MarkTen - SEPTEMBER 22, 2016 CHANGELOG:

• OUT OF BETA!!! NOW IN RELEASE!!!
• Fixed HSIC-related RR for good.
• Removed IntelliMM as it causes extra cpu load even when disabled.
• HSIC side-effect, battery life is AMAZING, just make sure to RESET FUELGUAGE.
• New settings to play with in Synapse, including sleep states and time spent in each.
• Figured out screen related stuff, see below. Enjoy. UPDATES - MarkNine - SEPTEMBER 19, 2016 MarkNine CHANGELOG:
• Implemented CPU HARDLIMIT control. I put a little write up in the main post above. It's working flawlessly in Synapse. This means that, realistically, you could see some VERY LIGHT overclocking in the near/distant future. MAAAAAYBE.
• Speaking of Synapse, I added Wireless Charge Amp Control in the Battery section. I just noticed it wasn't in there tonight. I don't know if anyone uses it for this device, but what hell, right?
• Synapse: the "quick cache drop" button now drops caches the regular way, and samsung's reserved way as well, so it's that much more effective.
• Added Cyanogen's mdp4 PCC colour control as well. Controls are in Synapse, and though it may seem like overkill on top of KCAL, this gives you fine-grained control over your screen display colour from values 1000-32768. Have fun ;)
• Disabled HSIC's constant search for a suspend state it will never find, hopefully putting the modem related kernel panics (random reboots) to rest for good. Pun intended.
• Cleaned up the mid and post-init scripts a fair deal. Boot time should be faster because there is less time wasted searching for devices and properties we don't [bleeping] have.
• Personal Update: my swearing problem persists.

UPDATES - MarkEight - SEPTEMBER 15, 2016 MarkEight CHANGELOG:

• fixed deep idle powercollapse for cpus.
• better Krait cpu power regulation (updated driver). UPDATES - MarkSeven - SEPTEMBER 15, 2016 MarkSeven CHANGELOG:
• This release fixes a bug in the cpufreq driver code that was introduced in the last version, making it perfectly okay to switch governors on the fly without worry of a kernel panic. I won't get into the technical details, but let's just say that I have to be far more cautious regarding cpu/scheduling updates from here on in. What you may lose in "smooth" performance, you will gain stability, dependability, and battery life gains from this release.
• cpuidle, sleeping has faster response time
• msm BAM driver resets asyncronously, hopefully helping with mdm modem airplane mode issue (modem sleeping is my goal for next release) -dma/cma/memmap stability fixes.
• DISABLED kernel mode neon, it was a difficult decision to make given that you've all gotten used to its snappiness by now, i'm sure, but the stability is impossible to ignore. It has always been an experimental feature and I gotta make this thing more consistent. -Disabled Google "Snappy" compression, I had tested it last version and am not impressed with it compared to other compression types.
• The install script makes a cool arc reactor graphic because fun.
• new led colors
• more features to come next release, this was another bring-up build UPDATES - MarkSix - SEPTEMBER 12, 2016 MarkSix CHANGELOG:
• This release focusses mainly on stability and default settings that are balanced, so that all users can benefit from it. I don't care if you think it takes too long to boot, because that is better than a full-throttle boot sequence that some devices' binnings/hardware cannot handle.
• Removed CM gamma control, it literally stopped doing anything after KCAL went live.
• Reverted Alucard Hotplug to its original settings, they are far more stable. Also reverted default governor to ondemand.
• Thanks to those who provided logs, as I have pinpointed and eradicated the random reboot. It was due to a qualcomm modem patch that was resulting in a kernel panic. Problem is solved.
• Modem sleeping issue is closer to being fixed, but involves me having to build a custom frankenstein of a solution for suspend which will take some time. It's on my list.
• Qtaguid has been fixed. It was denying network-related userspace processes of the permissions they needed to function properly. It was a security patch, which I try to keep up with because security is important. That said, functionality is more important and with custom kernels something has to give.
• Reduced execve restrictions to avoid init failures on ported roms.
• All battery and charging code is up to scratch now.
• More scheduling, cpu and kgsl fixes so that all governors (including the ones with graphics boost hooks, elementalx and electroactive) work properly once more.
• Sound: Re-doubled the slimbus overclock value, and sound is much cripser. THIS will be the default from here on in.
• timer function improvements
• cleaned up some display code, the display looks amazing again.
• Selinux code has been combed for bugs. Despite it being permissive, it still takes up a significant amount of resources. So it' s still important to mitigate its impact on fs, memory, and cpu usage.
• Sound Volume steps now have 0 delay when changing volume.
• improved some of the log in the Synapse backend, so the app will be less buggy.
• machinex is a good kernel again.

UPDATES - MarkFive - SEPTEMBER 10, 2016 MarkFive CHANGELOG:

• returned the Saw-Regulator (responsible for regulation of like everything) to stock values, as the change that was made previously resulted in instability. That means no more stuttery boots. -speaking of stuttery boots, the system now boots using the "Performance" governor, and then midway (once initialization is mostly finished) switches to the default "Hellsactive." Hellsactive tunables have been tweaked for performance from the start as well. -Regardless, this is a significant update, and your first boot will take longer than usual. Subsystem code has been repaired and thus modem operation will much better. -The line directly above means MODEM issues are like 99.99% fixed. -Battery - I fixed some functions in the pm8921-charger driver that will improve battery efficiency and SoC recognition of battery-life remaining. As a result, for this update I would RESET FUEL GUAGE in Synapse' Battery section. You'll see a massive drop in initial battery life, but your battery stats will be much more accurate from here on in. Also, after resetting, I charged my phone for like 15 mins and (thanks to fast-charge) it went from 50% to like 90%. But now battery life is improved so it's a trade off I recommend accepting. -Speaking of Synapse...I literally changed the "max cpus online" and "max cpus online during suspsend" variable names in all of the Hotplug drivers that use those tunables. Now EVERY Hotplug with those tunables (listed in Synapse) can be operated from the same controls, eliminating clutter and making Synapse more simplistic/effective. -Other Synapse improvements, including the addition of a CPU Voltage section, GPU Voltage added to the GPU section, LIVE cpu-temperature (avg of cores for now) display in thermal, and some more I think but I forget. -Thermal! Brought back stock thermal settings so y'all can get off my back ;) . But the live temp display is at the top of the section to act as a warning, like the ones on cigarette packs. (in my country we have gross, graphic warnings of the worst kind on our cigarette packs)
• CPU will stop panicking on governors with incompatible stats collection. (two lines of code to avoid a panic, like 5 words, ain't C an amazing language?) https://github.com/robcore/machinex/commit/fb7e4a9b8d12cc151bd709d0183ee6c35cabc248 -dma mapping: if an error occurs on boot, it now flushes the allocated memory for the mapped area that failed, as opposed to keeping it stored in memory. -added the cm gamma control settings in Synapse. It was always in the kernel, just not Synapse. TBH I don't think it does anything anymore now that KCAL is live, so I'll probably replace it with a different colour mod that faux123 made. It hooks the same code so with KCAL it might actually do something interesting.
• I SUPPORT NOTHING IF YOU FIDDLE WITH VOLTAGE!!!!! IT IS USED AT YOUR OWN RISK AND WILL PROBABLY TURN YOUR DEVICE INTO A NOTE 7!!!! that will scare them off, right? UPDATES - MarkFour - SEPTEMBER 10, 2016 MarkFour CHANGELOG: -ACTUALLY removed zen decision for good -more under-the-hood cpu and scheduling improvements. This bad boy is amazing for battery and performance. -default governor is now hellsactive, and it will actually stick because this update hijacks qualcomm's post_boot script. The important stuff is left in, the garbage they use to override our preferences is out. -updated the uninstaller script to reflect the change mentioned above. -reduced slimbus overclock from twice the "golden-ratio" values to the "golden-ratio" values. Now audio/video is perfect. -minor Synapse updates, but this update has such better performance that I'm rushing to get it out in lieu of adding too much fancy stuff. -random entropy generation is even faster, as it is now contributed by individual cores going online/offline. -probably more

UPDATES - MarkThree - SEPTEMBER 8, 2016 MarkThree CHANGELOG: -Added new governors, some for performance, some for battery life, and some for balance. As a reference, check out the link in my performance and battery life post. -More low-level scheduling/cpu code to bring those areas up to scratch -Slimbus enhancements, for stability as well as something experimental. All of us S4 kernel devs have tried out the "slimbus overclock" patch here and there, which makes audio communication in the hardware faster, but this is something different. Both ROOT and CLOCK gears are tuned to levels that are optimized using "golden-ratio" logic in order to correspond to each audio frequency step. Also, 44100hz & 48000hz freqs are added to the default playback adjust frequences, given that they are the most used frequencies in audio playback for most mediums. We will try it out together and see if its performance outweighs potential battery drain.

• Alucard Hotplug is now the default. -Use MTP while fastcharging is now set by default. I turn it off when not using it because my battery seems to charge faster with a wall charger when mtp is disabled. Use at your discretion. -added FSUTILS section in Synapse, with options to trim your data/cache/system folders at the click of the button, and also with handy buttons to remount your system/rootfs as rw or ro. -added samsung samp_spcm enable/disable capability, merely as an option. Frankly, i've not done extensive enough research either way and don't plan to, but I welcome "y'all" to test the results if it's something you care about. -removed Synapse options that literally did nothing -System is even faster -modem issues don't seem to be there, but i'm sure they'll pop up on a deepsleep now and then, still haven't fixed autosleeps RAW POWER for it yet. But you're looking at like, once every 50 sleeps so whatever for now... -Installer should account for Imperium Kernel's symlink, thus be more smooth when coming from his rig. -Removed Zen_Decision. It's a genius idea when having to battle with msm mp_decision, but we don't have it running in kernel or userspace so... -RETYPED ALMOST THE WHOLE BLOODY OP BECAUSE THE INTERNET SCREWED ME. Thank goodness for google's cached webpages. I'll bring the op back to looking presentable again soon. -more maybe? I'll letcha know if i think of anything else.

UPDATES - MarkTwo - SEPTEMBER 6, 2016 MarkTwo CHANGELOG: -Interactive-based governors not only work, but they work fast -A TON of low-level scheduling/cpu code to bring those areas up to scratch -Added Alucard Hotplug, and it's working in Synapse NOTE: The seek bar will not show up at first for Alucard Tunables. To get it working, select Alucard_Hotplug, then use the CLEAR SYNAPSE DATA button in the REBOOT tab(or delete Synapse's data in settings.) Have fun kids! -MODEM is much more stable -The battery/charging code is also much more stable UPDATE:Sep 6 part 2

• purely cosmetic. Updated hotplug descriptions in Synapse to include Lazy and Alucard hotplugs, and made sure that all kernel version info clearly states MarkTwo.

BUGS: A great deal of time (pretty much a year, maybe a year and a half?) went into ironing out some of the major bugs that came with upgrading so many crucial subsystems for a barely supported SoC such as ours. (ironically, it has like full 4.6 device-tree support so...cool) A good hunk of this kernel's infrastructure is 3.10-3.18-even a little 4.0+ based, and as such, there are certain drivers that I have hacked my way into preserving functionality, all while maintaining compatibility with android/touchwiz userspace. It's a delicate tightrope act to say the least. -Synapse has a built in log collection feature that will be of much use if you'd like to help to debug this bad boy. -Synapse governor tunables have issues sticking (sometimes). In the meantime, do it manually, go with stock values (I tuned each one myself in the source), or grab Flar2's Ex Manager/Faux's Fauxclock apps or a free one (make sure to delete Synapse from priv-app if you do go down that road though, or at least disable it).

• Again, drop caches once in a while. Persistent ram and dcache code need some more work, but I will get to it. Right now I'm busy making a fancy shmancy kernel thread.:This is probably not necessary anymore, but it's useful info in case you ever are in a jam.
• IMPORTANT: Reset your fuel-guage (also made a button for it in Synapse) if you find your battery/system getting laggy or weird anywhere below 50%. I still have some power-driver updating to do and the fuelguage gets wonky. [UPDATE]: it's a little better now.
• Nothing else off the top of my head, but I'm sure I'll be editing this page tons when something pops up.
