Freescale Linux kernel 3.10.17_1.0.0_beta

Freescale Linux kernel 3.10.17_1.0.0_beta

[Diego]

Hi,

I've noticed a new 3.10 beta kernel popped up in Freescale's git:
http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/log/?h=imx_3.10.17_1.0.0_beta

Is it already in the works for Yocto?

Bests,
Diego

I´m sorry, what do you mean?

We are working on the upgrade patchset, but the patches are not ready yet, do you want to participate in tests?

Testing this now.  Looks like it boots and talks to the network, USB, and serial 
ports on Wandboard Dual, but changes might be needed for U-boot to use a zImage 
by default, as well as changing the default fdt load address.  I had problems 
booting with the DTB using a uImage.

Also, do not use imx_v6_v7_defconfig.  Here, I believe that v6 and v7 refer to 
the ARM instruction set.  The new kernel seems to include some v7-specific 
instructions in some assembly code (specifically some lpddr2 code).  I'm using 
imx_v7_defconfig instead, which actually has more i.MX6-specific options 
included by default.

As an side question - is there an issue with defaulting to using zImage instead 
of uImage for Yocto/u-boot?

Can you try with fdt_addr=0x18000000 ?

No, I also think we should switch to zImage format. We only need to
update the script to call 'bootz' instead of 'bootm'.

I had problems with uImage when the DTB is loaded at 0x18000000.  It would give 
me errors like the following (note this was yesterday using 3.10.9):

Loading the zImage in the same place and using bootz worked.  I'm not sure if I

I think this would be nice.

If you have a chance, please send a patch that makes the conversion to
zImage usage.

I think this is a great idea but I believe we ought to make this for
all boards so we have it uniform across the boards; otherwise we'll
have a mix and it makes the support harder.

Considering we'd target this for 1.6, what would be the conversion plan?

Who could be responsible for each board for converting/testing?

Not sure, my thought was to leave it to the board maintainers. Unless I'm 
mistaken (which is a possibility), for some reason uImage does not work when 
booting with the 3.10.X kernels.  It that is the case then we either need to 
figure out the problem with uImages or others will be forced to use zImage anyway.

Here are the steps I've considered:
A) Send two patches to meta-freescale for meta-fsl-arm-extra to make the conversion:
    1) bbappend for u-boot to patch the include/configs/<board>.h file to use 
and boot from zImage
    2) Patch conf/machine/include/<board>.inc to set KERNEL_IMAGETYPE to zImage

B) Test the current stable kernels with these settings

c) Upstream the U-boot patch to u-boot-imx

Yes, in mainline U-boot I plan to convert them all at once.

I managed to boot FSL imx_3.10.9_1.0.0_alpha with mainline U-boot.

Haven't tested imx_3.10.17_1.0.0_beta yet, but I can try it next week.

Even if we manage to get imx_3.10.17_1.0.0_beta booting fine with
uImage, I still think that booting the zImage makes sense, as it can
avoid user errors by passing incorrect LOADADDR.

As I said earlier, I am fine with moving to zImage but we need to keep
3.0.35 and 3.10 working.

Another thing we need to consider is if we can migrate other SoCs too
(does 2.6.35 works with zImage?).

This may be done in our U-Boot fork, as we keep it backporting
mainline patches. BUT this means both 3.0.35 and 3.10 need to use
zImage as we cannot do conditional environment depending on the kernel
version without very ugly hacks.

Yes, but read above.

Please do one commit per board; so it is easier to revert (if needed).

Me too; All customer-kernels I've been doing (based on 3.10) been
using zImage and it works quite well. Did you test older kernels
(3.0.35 and 2.6.35, for example)?

I like this as a goal but this is not a simple change for the BSP; we
need to make it work for both supported kernels and test both. The
ideal would be to have all boards using zImage but we have a long way
for this...

Even if we convert all boards to zImage we need to keep support for
uImage as customers may be using it for their internal boards.

Yes, by "convert them all at once" I mean to send a series of patches
doing the conversion for several boards.

Booting a zImage is something that is really kernel version independent.

Then this defeats the whole purpose of the zImage transition then.

Right now, all my zImage attempts have been made using 3.10.17 beta, but I plan 
to go back and do 3.0.35.  I shall stay away from 2.6.35.  :-)

It does seem like a rather large change.  For each board, the changes are fairly 
minimal (as long as it works), but when you figure in 30+ boards, and for custom 
boards, that is a whole different problem.  I'd like to know what other 
maintainers think here.

Assuming that the default images filenames would be 'uImage' and 'zImage' one 
could do a hack-ish thing like test to see which file is present and then either 
bootz or bootm based on that.  I actually did half of this earlier today (minus 
the testing which file is present), by selecting bootz when image=zImage, and 
bootm when image=uImage.  While this would be nice to make it work by default 
with uImage or zImage, it is not very elegant and would need to repeated for 
each board config file, therefore it is a hack.  It would be much better for a 
simple 'bootany' command to test which type of image is loaded into memory and 
pick the appropriate one.

Sure but this does not mean we can convert all without proper testing, right?

It does not; I think we must be a safe bed for our customers and we
cannot shove down their throats a change like that. We must support
this at least for one more release to keep some time for them to
convert and adapt.

Good; this would be 'good enough' for us to consider the migration of
Wandboard for zImage.

Yes; I fully agree. We cannot underestimate this change as it has a
high impact the BSP.

Yes; this was the ugly hack I was talking about ;-)

Yeah, I was referring to the patchset. I'd be glad to participate to the 
tests, but I think I need to wait for Nitrogen6x boards adaptations.

Coming soon.

With the holidays, I just noticed the 3.10.17_1.0.0_beta kernel in
yesterday's thread.

Hi,

I'm also pressed to start using the new kernel (on i.MX6 / Sabre to begin with).
Are you sharing your work so far somewhere?

For those interested in early testing on SABRE Lite or Nitrogen6x,
we've pushed a branch to our Github repository:

	https://github.com/boundarydevices/linux-imx6/tree/boundary-imx_3.10.17_1.0.0_beta

Any guidance on how to boot this?  (device trees on ARM/U-Boot still baffle me)

We are in field trial right now almost complete for 3.10.17-1.0.0_beta but it is live with the manifest on the meta-fsl-bsp-release layer for those interested in trying it out.   I'll add user's guide once I have final version after field trial is complete.

As for work on master, I'm upstreaming the patches now and waiting on reviews from Otavio before it gets pushed into master-next.  

If you want to use our release in field trial start with the meta-fsl-bsp-release layer which was tested on top of the dora branches.  GA will be coming very quickly for 3.10.17-1.0.0.

Our meta-fsl-bsp-release has updates to components I have to upstream into poky and meta-oe so not all of it will be part of meta-fsl-arm.

Note this has a new graphics version that is not compatible with 3.0.35 kernel without kernel updates for 3.0.35 (Otavio has the patches).     The new graphics version allows us to support webGL in chromium.  We also provide support for the manufacturing tool in this release.

Hi Gary,

Bear with us. We're doing some more testing and finding some issues.

We'll post patches to the ML when things are in a more workable state
(in coming days).
