[Galaxy Tab 10.1 Android Development] decatf:
I tried to clean up the manifest and I'm running a build now that pulls only from github and not my local machine. So there will be one that's less messy soon.

Turns out that method I posted totally wrecks the stack. Running subsequent code in user-space gets kind of weird due to that. I don't know if it's just not possible to alter the CPU state too much within the kernel-space or if I'm doing something wrong. At the moment the only way I am able to redirect to a user-space lib is to only re-assign the PC. Then save state from the user-space lib before calling more code.

The kernel can read/write to user-space using get_user/put_user. So we can write the original instruction or the PC address to a struct in user memory as long as we know what user memory address. Doing the opposite (user-space to kernel) seems not so straightforward. This may only need to be done for bootstrapping the kernel trap and user lib during application launch anyways.

There is a cost when hitting a kernel exception but it doesn't seem too significant. For the neon vldr/vstr instructions there were tens of thousands of calls over a brief period (a day or so maybe) of use. It did not slow down significantly from what I could tell. If there were any impacts on benchmarks it didn't appear to change the results. That may be because the code generated by the ART compiler didn't impact any benchmark apps in the first place. I'm thinking most of the performance impact would be based the efficiency the NEON emulation rather than a bulk of kernel exceptions. That will definitely be more than a few stack instructions.

I think a way to reduce the exceptions is to do a look ahead. If the next instruction is also a NEON op then keep handling the next instruction until it's done. I think that might be possible since there aren't any control flow instructions. It all data operations.

Interesting...

The other configuration is to default to Optimizing and include a kernel that emulates NEON load/store instructions. That way xposed won't break and those that don't use it still won't be affected at all. I opted to stick with Quick compiler instead of load/store emulation because there is (supposedly) some performance impact from kernel exceptions as discussed above.
[Galaxy Tab 10.1 Android Development] UncleDick:
"Optimizing"

I've been looking for references explaining what exactly ART "Optimizing" means. For decades, compilers have had options to look through code to find variables that are set but not referenced, or that could be placed on the stack instead of stored/retrieved, rearranging code, loop optimization, etc. In addition to that sort of thing, I found vague comments about the ART compiler having

knowledge of specific processors

, implying that "Quick" code would run on ANY processor, but ART code for one processor would not necessarily run on another. Of course, that doesn't matter, because both Quick and code are generated on each device and put into the cache. If there is a technical reference to how ART works, I'd love to browse through it.

I remain almost giddy that this tablet may be the ONLY tablet (aside from Nexus models) that is even close to current with security patches.

Thank You. Thank You. Thank You

Followed the procedure, clean install but it will boot straight to recovery.

Any advice?
[Galaxy Tab 10.1 Android Development] jephimax:
Try flashing back to stock, then redo the whole process. Be sure to use the ROM/recovery intended for your device's model. Or try reflashing the ROM, if it really succeeded.

Hi guys. I've really been enjoying decatf's Rom's and the new Nougat one is looking very good. With the MM Rom I was using TouchScreenTune to increase screen sensitivity for use with a stylus (which is my preference). Unfortunately, the apk doesn't work in Nougat. I'm waiting to hear from the developer whether he is going to update it. In the meantime, do any of you guys know of another apk, or some other way of increasing the screen sensitivity as I really like using a stylus?

I have a question related to this rom, for my old tablet, I was able to use bigsys version and install android 8.1 on it, I want to try android 7.1.2 but each time I try to install it in twrp it keep showing that moving animation bar, I was able to get all the downloads I need for it, and I downgraded bigsys to twrp311-20171009_v2-p4wifi.zip

and it frezeing ok, I was able to get it to work from twrp311-20150814-p3wifi.zip

what I don't know is why on twrp311-20171009_v2-p4wifi.zip it didn't seem to work, also from twrp311-20180416-BIGSYS.zip under that one it seemed like it was frezzing up at the release keys text in it, I don't know if for some reason aosp-7.1-p4wifi-20190318 is slower to install than aosp-8.1-p4wifi-20181011.zip , I understand this tablet is older than some, and I do have a newer tablet that I got android 11 on right now, that also a samsung galaxy model tablet, but in any case, was wondering if that one zip file has something wrong with it since there more of a delay install 7.1 than 8.1 on this tablet, trying older versions to see which one works best, I tried 4.4.4 which has the camera working, but just the open gapps seem to crash under it and I going and trying all of them again, to just play with it, and see how I can make it work best, mostly for the play books otherwise I can just use my newer tablet for that too. since this one doesn't have access to my SD card, like my newer model does.

is it a common problem to have it install slower than the 8.1 version, also the latest 8.1 of open gapps seems to cause it not too even boot up correctly from there website for this tablet.

Yo, I'm aware gapps will cause a performance hit. I thought the gapps released by decatf are for tegra, since it has an "optimized for tegra" message when you install it via twrp and keeps getting mentioned in the forums. They crash like crazy though. I just needed Youtube.

Edit: I did follow that guide, didn't work, tried it twice and then variations of it to see if there was a failure point. Usually gapps and sometimes the main ROM.

On a side note, is USB debugging allowed on the ROM? I tried tapping the build number in settings but developer mode never turns on.
