Can somebody use magisk hide with this kernel?

I see no reason why magisk hide wouldn't work.

Unfortunately its not working. As I read at the Magisk forum, the Linux kernel version is old...

Hmm,interesting. I have no need for this feature,but have tested and thought it worked fine. We are stuck on Linux kernel 3.4 nothing can be done about that. If it doesn't work I can look into trying to a backport patch or something. I really have no idea. I'd have to look into this.

Im using this kernel in RR and have no issues with magisk hide and safetynet.

 

[Pat750]

Magisk hide also worked on an older Xenon (with the F) and Kernel 3.0. There are so many other things why hide wouldn't work...the Magisk thread is full of that issue...

 

[a-dead-trousers]

Can somebody use magisk hide with this kernel?

Yes. With 4.0 (the 4.0a I haven't tried yet)

 

[MikeT.]

13.3 works fine with v4.0

Is USB OTG and MHL supported by this kernel for the device? Thank you for the great work!

I thought USB OTG was enabled by default (in the stock kernel) As you can tell I haven't tested [emoji3]
Someone who has use for it needs to test and let me know. If it's not enabled I think its pretty easy to change that.
I thought MHL was an HTC thing. I'm also not even sure our device would support it. Do you know it does or? I also don't know much about this. Its something I can look into.

test v4.0

Thanks for creating and updating this kernel. I just tried your kernel for a week and I'm really satisfied with regard to performance and battery lifetime. Only thing I noticed were two reboots while my phone was in sleep mode. Any way to get useful logs so you can have a look at it?
btw: I'm using newest LOS 14.1 rom

Yeah,a few others have experienced random reboots as well. Strangely I have not had one with the latest kernel on here,v4.0.
I've been super busy lately,but have looked at a few logs provided to me and it's a kernel panic causing this. Thats no big surprise though and I haven't had the time to really investigate further. Hopefully sometime soon.

A couple of questions:
Have you adjusted the voltages?
What CPU governor are/were you using?
Which I/O scheduler?

As far as logs, if you share them I will certainly have a look and it is appreciated. This can be done via TWRP. Go to advanced and open the terminal emulator. Then type
cp /proc/last_kmsg /sdcard/log.txt
This will copy the kernel log to your internal storage. You can then share it here.

I've flashed the 4.0 version and wiped both caches. Besides that I didn't changed anything. I just installed kernel adiutor to see if the CPU is using the unlocked OC clock rates.
I've attached the log like you explained it. Keep up your work!

 

[Pat750]

Same here, only installed it, no changes in settings. Had two reboots when screen is off. Version 4.0, ROM DND2.1. No other issues, ROM is super fast now...

Thanks for the log. I had some time and looked it over. No kernel panics or oops or any of the such. This line however is repeated over and over...
"0 dw_mmc dw_mmc.2: data CRC error CMD19 CLKSEL 0x 03030003 1 Count 0"
This is your SDCard I believe (would have to double check) but the redundancy check is failing,so there must be corrupt data there....I assume.

Thanks for the feedback. Yeah,while I've had no reboots,most who have seem to report it happens when the screen is off. This is why I think it may be related to powersuspend or similar. Still looking into it. Hopefully I can sort it out.

Thanks for the prompt answer MHL is actually used by a variety of manufacturers, including HTC and Samsung, and the latter were a party in the development of the technology. The S5 has this feature but the Mini version do not support it officially. I am not aware of the requirements and cannot tell whether it's a matter of kernel tweaking. . .

Ahh,OK I didn't know this. It's something I can look into at some point. I'm really short on time lately,but I will try to look into it when I'm able.

A couple of questions:
Have you adjusted the voltages? -No
What CPU governor are/were you using? interactive
Which I/O scheduler? cfq
Kernel 4.0a 1500MHz

Please have a look at the log. I've noticed at least 2 random reboots in the last hours. The phone has got some problems with wifi reception at the current place but thats because of the building. Maybe that's a trigger?

Many thanks for the log and the detailed info. It is very helpful in these situations and appreciated. Sadly there is nothing in your log that stands out to me. I have also had random reboots with version 4.0a. That along with my lack of time is the reason I've yet to release a new version on here. Interestingly,my reboots seemed caused by the intelliactive governor and I haven't had one since changing. I think (hope) that a big reason for these issues is me changing the default HZ from 100 to 300. I haven't even had the time to revert that and try it out. Hopefully I will this weekend. I will post up a new test version on github if I do.

 

[spookcity138]

New test build up. Hopefully some of these random reboot issues are fixed,fingers crossed. Download Here
