OP3 Partitions

[DavidXanatos]

I looked on the partition layout of the OP3 and noticed that
1. the free space in the system partition is only about 200 MB (with OOS 3.5.1) so at some point there may be not enough space, is it possible to change the partition layout?
2. sde23 (/bt_firmware) is 1 GB large but uses only a few KiB i.e. its a waist of 1 GB :/
3. The flash seams to be divided into 6 devices and each of those partitioned, the last block device sdf has apparently 1.5 GB of unpartitioned space :/ what a waist!

What are you thoughts on the matter?

the nexus 5 has marshmallow on a 1gb /system, I think 3gb in OP3 will be fine especially since there's still empty space in it now.

 

[Taker18]

My thoughts are that this is in the wrong section

[DavidXanatos]

My thoughts are that this is in the wrong section

And which one would be the right one?


Also does anyone here know what what all this different small partitions do?
for example what is boot_aging apparently its some sort of boot image but its needier a backup of boot.img nor of the recovery.
I also wonder why xbl is so important to have the backup xblbak located with an own partition table in a separated flash section?

 

[Striatum_bdr]

Q and A section evidently this has nothing to do with dev

And frankly don't begin to mess with partitions, nothing good can come up from this.

 

[DavidXanatos]

Well, isn't understanding the partitions not part of development? IMHO one could learn something useful out of that.

 

[Striatum_bdr]

Development is programming. Building Rom and kernels.
This isn't dev add you don't propose anything related to a script, a program. You're just asking.

 

[DavidXanatos]

You can not program without understanding how the underlying system works. Respectively the better you understand the system the more you can get out of the hardware, for example here: http://xdaforums.com/optimus-4x-hd/development/rom-mahdi-rom-2-7-unofficial-beta-t2867590 this ROM apparently exploits a existing but unused partition of the p880 to add a new encryption feature which was not present in the stock OS.

Given how many partitions and unused space the OP3 has I'm sure someone can come up with a nice feature to exploit them. Possibly for a different approach on multi boot or may be some virtualization 1 Gig of space is more than enough for a hyper-visor.

> You're just asking.
Nope I'm finding out stuff and trying to find out more stuff....

I looked into the binaries and found something worrisome in XBL partitions contained in the 2nd and 3rd block device:

##This flag enables booting to UEFI Shell on LA devices.
##This UEFI in the current form should not be used for
##retail purpose. Fuse check will be added to avoid any
##possible security implications.

Also I'm wondering what the boot_aging partition does, apparently its some sort of boot image. But its needier a backup of the kernel (boot.img) nor of the recovery, I wonder what it is...

 

[Striatum_bdr]

I'm not discussing that. It belongs to Q&A until a practical thing comes up, then it can be in dev section.

 

[DavidXanatos]

So a sub forum called: OnePlus 3 ROMs, Kernels, Recoveries, & Other Development
is not intended to talk about development, that's so odd.
What sub forum than is intended to talk about source and hardware and boot loaders on a nun user level?

 

[t-ryder]

@DavidXanatos

No offense, Sir... but I guess OnePlus 3 ROMs, Kernels, Recoveries, & Other Development is more for like releases and stuff made by devs.
Maybe your thread belongs in OnePlus 3 Guides, News, & Discussion where you can discuss hat topic and find out stuff, as there are other threads a bit like yours.
Maybe ask a mod to move your thread? Just a suggestion.

 

[BRiANj64]

I'm not discussing that. It belongs to Q&A until a practical thing comes up, then it can be in dev section.

This thread does not belong in Q&A either. General maybe, but development could be right if it's about adding more space to /system.

 

[JumboMan]

I think debating on whether this thread should be in QA section or Dev section why not keep this decision on moderator.
why not just provide proper answer ( of course, if you know ).
I agree this question is more suited in QA section but i think this question can be asked in Dev section because it's very closely related to development.

 

[Sloth]

Hello,
I've moved it to Guides, New, Discussion, please discuss away.
This where it will reside unless someone comes up with a compelling argument as to why it belongs in "Other Development". I don't really believe it does.
Also please be civil to each other.

Cheers Sloth

 

[Akshaye22]

I think a practical case has come up with OOS 9.0.3 with no space left in partition. Adblock and Ifont are not able to write files. Please suggest

Delete play music and play movies from system partition. Should free up enough space for our mods.
