    Putting:

    # CONFIG_PM is not set

    in your configuration fragment will turn off an option, the BSP
    guide has a
    "# CONFIG_SMP is not set" as an example for this.


i thought it would and I have had this in my config too, but still it
get switched on. Guess there is something else in my config that sets this.
Will dive into this.

    There shouldn't be any race .. if this doesn't work:

    addtask kernel_checkout before do_patch after do_unpack

    Then there are some serious problems with bitbake's task scheduling.

    If you didn't do a clean between the two runs, the second is
    attempting to continue
    the patching and you still aren't getting what you want.


I did not do a clean inbetween. I figured patch would reattempt to patch
and, since the file is there it would continue.

The addtask line is there in one of the bitbake files.

The odd thing is that the exact same thing builds fine under 3.0.
Actually I was trying to move from 3.0 to 3.2 while stumbling on this.



    Without seeing what you've ported, or a work in progress I can't say
    exactly
    what is wrong, but your meta data is somehow wrong or completely
    missing.
    Have you set any meta or BSP SRCREVs explicitly ?


I have put my work-in-progress in:

https://www.dropbox.com/s/h58h6pq5b0f4u2s/patchproblem.tar.gz vi

you might want to edit conf/layer.conf as it has hardcoded paths.
If I go to meta-syrcxx/conf/machine/syrcxx.conf and set the preferred
kernel version to 3.0 things build fine.
Then I did set to 3.2 and it fails.
Note that apart from a PR bump the files
meta-syrcxx/recipes-kernel/linux/linux-yocto_3.2.bbappend
meta-syrcxx/recipes-kernel/linux/linux-yocto_3.0.bbappend
are identical (and I am just using files; so the same patches apply.

You've got a couple of minor problems in the files. dmaengine is
incorrectly referenced for 3.2. I've attached a fix for that. The
other items are just warnings..

I have fixes to make that bad configuration reference a hard error,
with a message during do_patch that high lights the problem .. for
master. But in denzil, what you got is what I'd expect.

Your max7311.patch also needs to be refreshed for 3.2, since it won't
apply as is.

After the failure, I refreshed it as follows:


 > bitbake -c devshell linux-yocto

# in dev-shell:

 # already fixed in master, but denzil requires this:
 > export GUILT_BASE=meta
 > guilt next
links/files/max7311.patch
 > guilt push -f
 # resolve conflict in drivers/gpio/Makefile
 > git add drivers/gpio/Makefile drivers/gpio/max7311.c include/linux/max7311_gpio.h
 > git clean -f
Removing drivers/gpio/Makefile.rej
 > git tag standard/default/syrcxx_top
 > guilt refresh
Patch links/files/max7311.patch refreshed

 > cp meta/patches/standard/default/syrcxx/links/files/max7311.patch $your_layer_location/meta-syrcxx/recipes-kernel/linux/files

 # the series is now clean.

I then cleaned linux-yocto and restarted, it configures and builds
after that (and eventually gets a build error, but that looks like an
issue with the code on the 3.2 kernel .. and is for someone else to
fix :)

As for the CONFIG_PM, it's a Kconfig "feature" that is causing you
pain. You can't directly "access" (enable/disable) and option that
doesn't have help text, since the help text makes it "user visible"
and hence a configuration knob. (Don't blame me, I don't condone this,
but it is what it is). In this case you need to blast one of the dependencies
to disable it. I turned off CONFIG_SUSPEND to get CONFIG_PM out of
my final.config.

I inlined my three changes here, the last one is the patch refresh
for drivers/Kconfig, so it's not all that useful :)

Cheers,

Bruce

BTW our board is a powerpc 8313e based board (modeled after mpc8313e-rds)

One other thing I noticed; do_install seems to take quite some time; not
sure why this is (haven't investigated).

Best regards, Frans
