Increasing mamba and venom kernel partition to 6MB

anomeome · February 8, 2021, 10:56pm

Compiled 5.4.x with the bot default config.seed

3212994 Feb  8 15:15 linksys_wrt1900ac-v1-kernel.bin

as it is smaller than the above 5.10.x I did not bother flashing. I tried the same with 5.10.x but it fails to compile. Issues above and beyond what I have run into with my personal config.seed on 5.10.x. So 5.10.x has a way to go yet. Using the above numbers from 5.4.x, I would guesstimate ~3.4+M on a bot build of a 5.10.x for mamba. Some room to breathe at any rate.

I took a look back to see if there was any indication in the git log as to the rational behind the decisions made regarding the kernel size numbers of the two targets of interest, did not find much; @lantis1008, do you have any insight on this.

@ghoffman , I don't think the uboot source(s) have ever been released for the wrtpac targets, at least I have never come across them in my travels. People are just pushing a BLOB of unknown origin to their device. Unless they took the time to pull the BLOB from their own device, in which case they are pushing their own unknown origin BLOB, well...

Right, I have compile and flashed the resized patch firmware for Venom (WRT32x), here is my kernel log

How ever checking the sysupgrade image shows a 3mb kernel in it.
How do i check the .img file's kernel size or how do i findout on the router.

Just blindly followed the GPL because it was my first device support patch, I didn't know any better, and it worked ok

That indeed looks correct, awesome to hear that venom too works!

How ever checking the sysupgrade image shows a 3mb kernel in it.

That is expected, the kernel will only be as big as it needs to.

How do i check the .img file's kernel size

Extracting the sysupgrade and running ls -la kernel or file kernel will give you the sizes.

anomeome · February 8, 2021, 11:29pm

If you are using the above two config settings, you presumably have patches in your tree to shrink things, otherwise your build presumably would have failed for the wrt32x (prior to these patches). At least the bots currently fail due to the size exception with similar setting. Some kmod removals maybe?

solidus1983 · February 8, 2021, 11:36pm

Thats the thing i haven't removed the kmods, infact i have added a load to both this image and to the one before it.

However i have noticed the size (using the same config) has changed.

Pre-Resize Patch r15697:

Post-Resize Patch r15710:

As you can see the factory img has grown for the wrt32x by 3mb but the sysupgrade stayed the same. However it boots so thats a start.

If you DM me i will give you the link to the webserver so you can check the mainfest file and config file.

anomeome · February 8, 2021, 11:53pm

You can just push'em to a bit bucket and post the link(s)

cat file | nc termbin.com 9999

but a git status indicates a clean tree, colour me confused.

I don't use git am, but if memory serves something like

git log --oneline

should show what you have added. You would have to have changed something relative to target/linux/mvebu/config-5.4...

To make a 5.10.x build work I was changing some kmods to loadable by way of adding file

target/linux/mvebu/cortexa9/config-5.10

# CONFIG_EXT4_FS is not set

The merge request:

nitroshift · February 9, 2021, 4:19am

I have been in contact with Linksys and Marvell a long time ago, asking them to release the code for the 3200 u-boot. I even asked for support from Wolfgang Denk, one of the founders of u-boot project. They failed to provide the code, although their generic modified code is available on github: https://github.com/MarvellEmbeddedProcessors/u-boot-marvell

@anomeome
hmm? are you sure that is intended for me?

anomeome · February 16, 2021, 7:26pm

Wondering if you intend on submitting your 5.10.x patchset for mvebu now that the 5.10 generic patchset is in master

nitroshift · February 17, 2021, 4:38am

It is available on github but will submit it to master today.

LE: submitted.

SkewedZeppelin · February 17, 2021, 6:29pm

@nitroshift
Your mvebu 5.10 patch that you sent to the mailing list includes numerous issues:

It has no subject and no description.
It wasn't picked up by Patchwork.
~~It doesn't successfully apply on master. Immediately fails at 002-add_powertables.patch~~ user error here
It seems to be missing patches compared to 5.4, if they aren't needed anymore they should be noted in the description.
The patches don't appear to be numbered correctly. eg 002-add_powertables.patch vs 302-add_powertables.patch.
999-DNM-dts-mamba-resize-3MB_to_4MB.patch needs to be dropped.
You removed the SPDX identifier from target/linux/mvebu/Makefile.
KERNEL_PATCHVER should be left and have KERNEL_TESTING_PATCHVER bumped instead.

nitroshift · February 18, 2021, 4:10am

Thanks for the heads-up! Will look into it today and create a pull request. Patch 999 was dropped in the next message in list. Forgot about it when sent the message.

dominick-han · February 18, 2021, 5:48pm

I see that they are cutting openwrt-21.02 branch already, do you (or anyone) know if 5.10/larger kernel partition will make it to 21.02?

Also, thank you for all your work on mvebu/WRT AC series!

anomeome · February 18, 2021, 5:57pm

Until one of the methods being tried makes it into master there is no chance, with PR3852 most likely. Subscribe to the PR to get notification should something develop.

dominick-han · February 18, 2021, 6:34pm

Sorry let me rephrase my questions:

Hopefully the 4/6MB kernel partition patch get merged soon. (I got a rango a few weeks back before this PR was opened, to just play with snapshot)
If none of the kernel partition increase PR makes through, does that mean there won't be official images for mamba/venom in either master/snapshot or 21.02?

The 5.10 patch (or any patch for this matter), when/if it makes it into master within the next few days, who/what decides if they are going to cherry-pick that to the 21.02 branch?

bmork · February 18, 2021, 6:54pm

One of the reasons given for branching 21.02 now is to be able to merge 5.10 patches into master without affecting the next release: http://lists.openwrt.org/pipermail/openwrt-devel/2021-February/033804.html

Stabilizing a new kernel version and moving all or a significant number of targets to it takes a lot of time.

So I believe it's unlikely that any 5.10 patches will end up in 21.02.
