Is there a case to be made that a maintained (a monthly security patched build) version of LOS 14.1 would be more practical for users and less work for a developer?

I know 14.1 is no longer officially maintained by lineage any longer but does it need to be for the shieldtablet? Do we not only need security patches for a system that works well with 14.1?
[Shield Tablet Android Development] Disrupthor:
Anyone got a backup of latest build? On lineage is gone already...
[Shield Tablet Android Development] TheToxicant:
So 15.1 is done with the shield but the 16 is still in progress or is that finished as well?
[Shield Tablet Android Development] h4waii:
Wow, all the mirrors get purged extremely quickly when a build is removed.

Does anyone have the latest build and can throw it up somewhere?
[Shield Tablet Android Development] TheToxicant:
I might have it on my pc I'll check in the morning.

Yes please, upload the files needed to be used, i currently use stock rom and i want to get rid of it...

Long story short, support for the shield tablet is currently dropped and uncertain if it will be picked back up(again) and Micro G has a fork that has not been stopped(yet)

can't we switch to the oss graphics stack ?

https://www.phoronix.com/scan.php?page=news_item&px=collabora-hwcomposer-hwc-post

theoretically mesa should have the bits : https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-Tegra-Mesa-2018

maybe the showstopper could be the kernel btw, as we are stuck on 3.10 and I think 4.9 is needed at least
[Shield Tablet Android Development] Steel01:
[MENTION=4756930]Alastor89[/MENTION] That's something I've worked on off and on for a while now. It goes a bit further than that though. To really use drm graphics properly, we need a much newer kernel, yes. So, I've been tinkering with mainline kernel support. Nvidia has pushed a lot of their hardware support to the mainline kernel, though not nearly everything needed for any of the consumer devices. But I'm actually poking at mainline support for t210 (the shield android tv) and t114 (the original shield portable) right now. T124 work will come if I get those working. It's a lot of non-trivial work, though. And also consider that while successful mainline support will virtually immortalize these devices, some features may never get re-added. Hardware video acceleration (possible via vdpau, but someone would have to write a omx to vdpau wrapper) and geforce now are the main two that come to mind. But anyways, this is all very much a work in progress and nothing even boots right now. It's not feasible to ship until Q when google brings the drm stack back in line with upstream either.
[Shield Tablet Android Development] The-Saint2k:
Since Lineage OS 15 is currently not continued, I created a LineageOS 14.1 build. Security patch level is June. I tested WLAN and Amazon Prime Video and could not find any problems. If there is interest I would publish builds monthly.

Build Info: it was created with the official docker image of Micro G, but without any Micro G services, so G-Apps can be installed.

[Shield Tablet Android Development] Sir Daniel III:
Omg thank you
[Shield Tablet Android Development] mirhl:
With the switch community onboard, I think Tegra has a very rosy future ahead (well, the models with modern desktop gpu architecture at least)

But I thought the Pixel C and Chromebook folks had already got mainline booting?

Also, isn't mesa providing openmax for radeon and nouveau drivers?

EDIT: also also
[Shield Tablet Android Development] john_matrix:
Thank you The-Saint2k!

Can it be dirty-flashed over latest 14.1 official?
[Shield Tablet Android Development] Snah001:
Thanks for your effort to bring 14.1 with latest security updates and yes of course we would appreciate when you could bring monthly updates!

Now will flash back to 14.1 and we will see if a 16 Lineage is possible by Steel01.
[Shield Tablet Android Development] The-Saint2k:
I think so, since it's merely a continuation. But I deleted it completely before (System & Data). However, I had exchanged the AOSP WebView engine for Bromite (not in the build i have published) and there was a Dirty flash no problem.

If I have made enough post in the forum, I may also allowed to create a thread for the 14.1 Builds

Monthly builds would be fantastic.

If you could add oms support for substratum themeing that would be the dream build. Actually user MSe1969 on the Motorola G 2015 (osprey) forum is already doing this for lineageOS 14.1 for the osprey.

He was also gracious enough to build a one off lineageOS 14.1 with microg and oms support for me. It works perfectly.

May I suggest contacting him for advice on enabling substratum support?
[Shield Tablet Android Development] The-Saint2k:
I will create a new BUILD tonight, which will be uploaded tomorrow morning after German time. The only problem is that I can't test it because the tablet is currently on vacation with my son.

On the subject of substratum, I can't give much hope since I'm rather a beginner with passion in the field of creating Android BUILDs. But currently I am trying to integrate the Bromite WebEngine on a test device using his Github project.
[Shield Tablet Android Development] The-Saint2k:
I uploaded the current build with July Patches. But I have to say that I couldn't test it because the tablet is on my son's vacation. I can only test it myself on Friday. So if anyone is brave, please let me know if it went well.

I changed the cloud memory to AndroidFileHost.

Having some issues with my original Shield Tablet (the one I killed the kill switch - so really I'm a tablet up in life...), had some issues today flashing a new image of TWRP. Ended up all the way back at TWRP 2.8.7.0 before it would work. Now I've attempted to instal the June Lineage package from GtrCraft on the previous page but it's failing and returning "This package is for device: shieldtablet; this device is . " Some reading suggests an update to TWRP and a reboot might fix this....but therein lies my problem.

Any suggestions?

For me it did not work although I flashed the June build clean it gives an error when flashing dirty stating it can't flash on a not compatible data partition.

[Shield Tablet Android Development] BakaPhoenix:
From what steel said we probably will move directly to 16 if he or someone else manage to fix the problem, and 15.1 will be dropped

15.1 is already dropped.

I think so, since it was already officially a lineageos build. However, it has all the disadvantages steel01 and others already mentionedl(like here ) . When I'm back from vacation, I'll try it. ( in 1,5 weeks)

But you'd have to test it because I want to stay at 14.1.

Which partition couldn't mount?
[Shield Tablet Android Development] The-Saint2k:
Did you ever erase everything? System, data, cache?

Like groegerjo, I have no problems, neither with the June build nor with the July build. I also have the latest version of twrp. Don't you have any problems with other Roms?
[Shield Tablet Android Development] Snah001:
With June build I wiped all partitions. Then flashed the June build and gapps etc. Did set the device up completely.

When trying to flash July build dirty it states the data partition is not compatible. Data partition is and was ext4.

sorry noob here. to flashing roms and such. was wondering if there is any issues with the current stable build of lineage for shield tablet. and is it compatible with the 32GB version that is LTE. (Worldwide version)

would this effect playing games on the tablet at all?

(Hardware video decoding does not work)
[Shield Tablet Android Development] TheToxicant:
I am running an LTE model using the build from this link https://xdaforums.com/showthread.php?p=79944499 and other then not being able to use my shield controllers and small hang ups with the screen I havnt had any major issues.
[Shield Tablet Android Development] TheKicKer69:
is this ROM still being updated? if so wots the frequency?
[Shield Tablet Android Development] multiwirth:
I don't think so.

14.1 was discontinued for all devices and 15.1 for the shield tablet are at least no longer offical since something inside the rom was broken if i got it right.

So if there are no builds on the offical download page, then you should look on xda for unofficial builds.

I still use 14.1 because in Android 8 and 9 the hardware decoding of media is broken so for example youtube 1080p will stutter and/or drain the battery very fast due to software renderer.

Fixing HW acceleration

Hi,

Thanks for your efforts so far, I want to assist you on fixing the HW acceleration. I am experienced in C++ programming. I have done some research and found a board https://developer.toradex.com/products/apalis-tk1#software with same SoC with the tablet. This board has mainline kernel 4.9 support. Maybe we can use it to port the latest kernel on the device. I don't know where to start debugging kernels for a device. Is there anything I can do to help?
[Shield Tablet Android Development] TheKicKer69:
Hope u guys cooperate; that would b AWESOME!!!
[Shield Tablet Android Development] NinjaCoool:
Cheering for you guys! Let's get it!
[Shield Tablet Android Development] Alastor89:
The problem as [MENTION=1416222]Steel01[/MENTION] said, before is that there is a memory leak in the graphics stack, because of the closed nvgpu blobs.

That could be solved either reverse engineering newer blobs from the shield tv which got pie and shimming ours (as far as I think) , or by switching to the OSS gpu stack (so drm kernel drivers and mesa library), but for being able to use the OSS stack we will need to run on the mainline kernel.

If you want to try to work on something you can start by building los-16.0 from the CMShield repos and start grabbing logs to see whats happening.

I arrived to the point that it boots but crashes to the following error : NVSI : ERROR: TSecCheckPermissions() - 0x00000002 (plus other errors on camera)
[Shield Tablet Android Development] Steel01:
Yeah, I broke shield tablet pretty badly on 16.0 when I pulled in the P updates from the satv. Haven't put the time into figuring out what the real issue is yet. But even if it did boot, the nvgpu issue makes it virtually unusable (like, it normally doesn't last ten minutes before soft rebooting). There's a couple different possibilities to get this working again, but there's things I'm waiting on plus I've got other things I'm working on first atm.
[Shield Tablet Android Development] Alastor89:
As always thank you for the progress update ! :)

When the trees are in a "booting" shape if you can ping me I'll be happy, as I want to try to add settings for power, display calibration(I grabbed sysfs interface from nvcplsvc.apk) and the touch calibration stuff that stock has
[Shield Tablet Android Development] Afshin44:
I appreciate the response, is there a guide on how to setup an environment so I can build and debug the device to see what’s happening? I am new to this. Also about nvgpu, I looked around the sources from nvidia git repos, I don’t know what to look for until I have a dev environment ready.

Also your error code seems like a broken permission check? I can’t comment really if I can reproduce the bug.
[Shield Tablet Android Development] Alastor89:
Yeah sure, you can follow this guide, https://github.com/nathanchance/Android-Tools/blob/master/Guides/Building_AOSP.txt

Just make sure to use lineageos 16. Then instead of doing breakfast shield tablet just grab local_manifest from here : https://gitlab.incom.co/CM-Shield/manifest/blob/lineage-16.0/default.xml
[Shield Tablet Android Development] TheKicKer69:

[Shield Tablet Android Development] multiwirth:
there should be unoffical builds here but i think HW decoding is still broken so for watching netflix and youtube, you won´t be able to stream 1080p and/or have a huge battery drain.
[Shield Tablet Android Development] mithrado:
i am running this ROM. Anyone has an idea to make the nvidia shield controller work?
[Shield Tablet Android Development] p3dboard:
If it's the original controller, wifi only model, you'll have to use a usb otg connector with a usb cable.

Only stock Nvidia roms have all the parts to to talk via wifi. If it's the 2nd generation controller, you should be able to connect via Bluetooth

I had to factory reset and reinstall everything.

My another android device (OnePlus One, Official LOS) does not have trouble with the same module.
[Shield Tablet Android Development] arden1984:
Is this device even maintained anymore by Lineage?
[Shield Tablet Android Development] Steel01:
There's no official builds right now, no. I'm still working on the device, though. Trying a few different things to make it run current android versions. Making some progress here and there, but not really enough to report or give previews of. It's a slow process when I'm working on like twelve different tegra devices.
[Shield Tablet Android Development] Steel01:
Well, some good news for a change. Thanks to arttttt of the mocha / MiPad group, we have a potential fix for the fence leak that caused issues with the shield tablet graphics stack on 16.0. Initial tests tonight are looking promising. I'm going to be doing stress tests over the weekend and next week to see how well it holds up. If I don't find any horribly breaking issues, I may release an experimental version over the weekend. There's still going to be a lot of little fixes needed, though. The tablet has fallen behind my work on the console, so who knows what's broken here and there.
[Shield Tablet Android Development] john_matrix:
Thank you very much for continuing the development of Lineage OS on the Shield Tablet! ;)

[Shield Tablet Android Development] M4rkusX:
What are the results of your testing so far? As you have not released any test version, something broke?

Nevertheless, thanks for still working on our aged shield tablet. :)
[Shield Tablet Android Development] Steel01:
Yeah, sorry for the lack of update.

It does boot, but there are several issues that need cleaned up. We're seeing roughly a 33% performance loss as compared to 15.1 and earlier. And the interface isn't particularly smooth. I've got some issues with the powerhal and hint service that I need to sort out as well. That said, more stuff 'just worked' than I expected. Like, I had pulled in fosters audio hal and updated shield tablet blind while the device didn't even boot. But once the graphics fix was found, audio was working just fine. So, it's a mixed bag right now. The core stuff works, but it's not what I would consider up to par, not yet.

[MENTION=1416222]Steel01[/MENTION] Hello heavy duty pusher for our devices, any progress or developments?
[Shield Tablet Android Development] Steel01:
Well, here's some news I never expected to report. [MENTION=766721]ryanbg[/MENTION] did a lot of research on the hardware video acceleration issue. And found the root problem. Missing intrinsics (low level compiler / libc stuff, I'm not going to do a full explanation of what they do). The most annoying thing is: I already had to fix that for the normal graphics stack. And because nvmm didn't log proper errors, I never thought to look at intrinsics there. Pick in one of my old patches and... stuff works fine. Unfortunately, that patch cannot ship for official builds, so we've got some more work to do to make it shippable. (and a lot of other stuff too, 16.0 is no where near polished). But yeah, sneak peak: I was playing Netflix videos at 1080p.

Long live the shield tablet

[Shield Tablet Android Development] Steel01:
I would have sworn I responded to this earlier... But I guess either my tablet or the internet ate my post.

So, I had considered running my own 15.1 builds again, but I think I'm just going to leave that to the ones already running unofficial builds. Two things needed:

1) Revert https://github.com/LineageOS/androi...mmit/82d2b4c28b8249ab86cd2e4b7fb98ee892d182fb

2) Pick https://review.lineageos.org/c/LineageOS/android_bionic/+/268655

In other news. With some help from the switchroot crew and elsewhere, we finally got the Nvidia Games app working correctly on 16.0. I was able to pull up Borderlands over Geforce Now on my tablet. That's something else I was beginning to think would never work again, but here we are. And before anyone asks, I'm not wanting to backport the fixes to 15.1, but if someone wants to try themselves, I'll give some pointers. But anywho, 16.0 still has issues it needs fixed, but it's really starting to look up. In some cases, the K1 devices are doing better than the newer X1 devices like the satv. Which is... special. But it is what it is. Trying to get them both as polished as possible.
