Hi Darren.
Attached is config.diff as you requested. However I noticed that Kconfig
also suffered changes, so just for the record, I ran diff on it too
(althougth "mine" version came form 3.8.13 and the "orig" version is from
3.10.35).
Thanks.
Post by Darren HartPlease just run "diff -Nurp config.orig config.yours > config.diff"
You can find the .config in the build dir of the linux recipe. If you
don't have an angstrom or poky build around, you can always use the binary
image that came with the board or download it again, and fetch the config
from the running system in /proc/config.gz.

Subject: Re: [MinnowBoard] Kernel .config file lacks CONFIG_FB_DEFERRED_IO
Post by Ferchu RHi Darren.
I am going to run a Windiff or something similar between my already
modified files (/usr/src/kernel/.config and
/usr/src/kernel/drivers/video/Kconfig in my Minnowboard) and the original
"sotck" files, but I don't know where I can find them. Can I find them on
the bitbake Minnowboard directory structure
(/opt/minnowboard/ourbuild/setup-scripts) ??.
Note: I found a .config in
"/opt/minnowboard/ourbuild/setup-scripts/build/tmp-angstrom_v2013_12-eglib
c/sysroots/minnow/usr/src/kernel".
Thanks.

If you find a particular task you want to perform is not adequately
covered there, please do let me know.
As to support for this particular feature, if you can send me the delta
between the stock config and the one you modified, I can probably just
add it to the minnow config fragment and you can then just rebuild the
angstrom image per the angstrom instructions using the latest git of
meta-minnow.
If all you want to do is quickly rebuild the kernel (and don't care about
packaging, etc), then Angstrom provides a linux-dev (or similar) package
which you can find using "opkg list" and install with "opkg install ..."
and the kernel source will then be in /usr/src/linux...
There you can "make menuconfig; make; make modules; make modules_install;
make install" as per usual.

Subject: Re: [MinnowBoard] Kernel .config file lacks
CONFIG_FB_DEFERRED_IO
I seted up bitbake for building Angstrom on Ubuntu 12.10. My new
strategy is not to to build the kernel module using the same Angstrom
target system as host, but building it on Ubuntu targetting the
"minnowboard environment". As I should pass KERNEL_SOURCE_DIR as make
argument when building the module, what path should use in this case, if
the directory structure is "/opt/minnowboard/ourbuild"?.
Thanks.
Hi Darren.
The driver's source code uses a struct named "fb_info" that is defined in
fb.h (this file is part of the standard kernel. Within the definition of
#ifdef CONFIG_FB_DEFERRED_IO
struct delayed_work deferred_work;
struct fb_deferred_io *fbdefio;
#endif
Because of that, when CONFIG_FB_DEFERRED_IO is not present, member
fbdefio are not included in fb_info struct, thus I am getting the error
at build time.
The manufacturer gave me the advice of running "make menuconfig" on the
kernel source directory and add "Displaylink USB Framebuffer support"
option. After that, both files (.config and Kconfig) were automatically
changed in a way all entries involving CONFIG_FB_DEFERRED_IO now are
equal to those of their counterpart in Ubuntu. So I think the files at
this time are not th problem. The manufacturer told me too that I should
re-compile the kernel for the changes to take effect. How could I do
this?. Should I only cd to the kernel source directory and run make?. I
am running all this stuff in the same Angstrom Minnow system.
Thanks and best regards.
The hardware manufacturer has told me that just adding
CONFIG_FB_DEFERRED_IO
to the .config file, is not going to work. It is necessary add a section
which make reference to the CONFIG_FB_DEFERRED_IO feature in the KConfig
file.
I hope that someone can advice me if this is the right approach and if there
is a template to add a new section to this KConfig file.
I'm not really sure how to answer your question. The structure you
reference in the include/linux headers is impacted by whether or not
CONFIG_FB_DEFERRED_IO is configured in or not.
Does what you are trying to do work on a typical desktop Linux
distribution? Ubuntu, Fedora?
If so, can you compare the files - exactly how are things different?
