RE: [boinc_projects] platform string for Linux on ARM

[Rom Walton]

Okay, I’ve pushed out a new build which will have the alt platform defined for all three 64-bit platforms supporting their 32-bit flavors.

 

I found evidence in the standalone toolchain that leads me to believe that both 64-bit and 32-bit executables are supported on 64-bit platforms.  Namely there are both /usr/lib and /usr/lib64 directories in the virtualized sysroots.  Both containing the same libraries.

 

I found some documentation, namely:

https://developer.android.com/ndk/guides/standalone_toolchain.html#abi

 

Describing the preferred parameters to pass to gcc to support armeabi-v7a and an additional piece of information about a bug with the cortex-a8 processor.  Applying the extra parameters seems to have cleared up the execution failures on 5 of the 13 devices Google tests us against in the play store.

 

I believe 7.4.51 will be a good build to get out to the public.

 

It is important to note that the devices Google tests us against are all ARM devices.  So if anybody has an x86/x86_64/mips/mips64 device you are willing to test out the new build on, let me know how it goes.

That’s the part I haven’t been able to look into yet.

Up until a couple days ago I was unaware that BOINC was previously working on the Galaxy S6.  So, at least for that device, it is capable of running 32-bit ARM apps.

I need to find out what the rules are for Android before I go monkeying around too much.  We were accepted into a testing program Google offers to run your app through a robo testing process on a bunch of (13) devices.  We are still failing on a class of devices 32-bit devices where the architecture is ‘armv7l’.

Hopefully I’ll be making some more headway on this during the weekend.

I would think that it should be added, assuming they can run the 32-bit versions, of course.

There looks to be problems with 7.4.51

1. A host which detected the CPU correctly with 7.4.43 now does not detect any CPU.
https://setiathome.berkeley.edu/show_host_detail.php?hostid=8006871 showed as ARM AArch64 Processor rev 2 (aarch64) with 7.4.43, Number of processors 8.

It got a new hostID, because it now has a new name, plus a new CPU of sorts: https://setiathome.berkeley.edu/show_host_detail.php?hostid=8034503

CPU shows only as "Number of processors 8", no other distinction.

2. I suspect we have one Nexus 5X on the forums (https://boinc.berkeley.edu/dev/forum_thread.php?id=11070) where the projects list is empty, it shows only the option to use an account manager, everything else is not available.

-- Jord van der Elst.

[Seke Rob]

There's several reports over at WCG with empty project pick lists, only getting Account Mngr as option, no menu icons left or right top. Galaxy S6 with marshmallow. One has 7.4.51 so proposed to go back to 7.4.43.

On my Nexus 7 with 6.0.1 and 7.4.51 no issue but those with problems were clean installs on new devices.

Another ping about this, as this version is still the one showing on the Google Play Store. It may not be a problem for the 32bit CPUs out there, but together with download problems, non-populated project menus and not detecting of the CPU, I feel 7.4.51 needs to be retracted. Everyone with problems went back to 7.4.43 and they have no problems with that one. So why keep version 7.4.51 as recommended? (It's not even an alpha)

Cheers,

-- Jord van der Elst.

[Rom Walton]

I’ve deployed a new version which should fix this issue.

 

Basically the Android GUI didn’t know anything about the alternate platform mechanism.  The GUI hard coded what platforms it supported instead of querying the client for them.  I added the alternate platform to the list of supported platforms in the project list.

Report from the forums (https://boinc.berkeley.edu/dev/forum_thread.php?id=11079)

On a Nextbook tablet, Intel Atom x86_64, Android 5.0 BOINC 7.4.51 and 7.4.53 hang immediately upon initializing. They don't get past the title screen.

I've asked what it does when returning to 7.4.43 (although that one won't detect x86_64 CPUs, I think?)

Cheers,

-- Jord van der Elst.

[Jord van der Elst]

This same user installed 7.4.53 on two ARM devices and there it runs fine. He just can't get past the BOINC title screen on .53 on his Intel Atom.

He's now installed 7.4.43 on it and that works fine.

-- Jord van der Elst.

[Rom Walton]

Well that is interesting.

 

We were getting sporadic reports of the title screen lock-up issue with .43, on a mix of all device types.  Which lead us to the need for arm64, x86_64, and mips64 platform types.

 

Google allowed us to use one of their device testing facilities, which unfortunately only had various arm based devices, and I was able to track down and (maybe fix?) the additional issues with running BOINC on arm based devices.

 

I guess I have some more research to do for x86_64.

Hi Rom,

This fix didn't do it for this device: https://setiathome.berkeley.edu/show_host_detail.php?hostid=8038962

It's still got no CPU detected at all. Just an empty string and that there are 8 cores/CPUs. That is with 7.4.53

Another report at https://boinc.berkeley.edu/dev/forum_thread.php?id=11082 says that now projects show up in the Add Project listing that do not have ARM/x86 for Android applications at all, like CPDN, Milkyway, primaboinca etc. I see the same thing on my Android (ARM v7) device.

Pushing this one back into view.

Thread at Seti with plenty of people with non-working BOINC: https://setiathome.berkeley.edu/forum_thread.php?id=79858

Can we get a new version out with fixes, please? Or is development for Android at the moment at total standstill?

Thanks,

-- Jord van der Elst.

[David Anderson]

Dev/maintenance for Android is at a total standstill, unfortunately.
Rom, is that true?
Anything we can do to recruit some help?
