Hi all,
I am working on MeeGo TV vertical. I have a question on how to export
header file from kernel module for user space library.
For example, we have a header file named sec_common_types.h, which is
used for both kernel driver and user space library.
I think we should export this headers file by kernel package rather
than including this header in both kernel driver and user space
library, am I correct?
Currently, I add this header file to a new create rpm package
kernel-adaptation-intel-tv-headers
<http://dhgobs.sh.intel.com/package/binary?arch=i586&filename=kernel-adaptation-intel-tv-headers-2.6.35.3-8.1.i586.rpm&package=kernel-adaptation-intel-tv&project=MeeGo%3ATV%3Adevelop%3Adhg_sdk%3Apc21.1&repository=MeeGo_1.2>
generated by kernel-adaptation-intel-tv
<http://dhgobs.sh.intel.com/package/show?package=kernel-adaptation-intel-tv&project=MeeGo%3ATV%3Adevelop%3Adhg_sdk%3Apc21.1>
package. Is this a acceptable solution?
BTW, I checked kernel-adaptation-intel-tv-devel
<http://dhgobs.sh.intel.com/package/binary?arch=i586&filename=kernel-adaptation-intel-tv-devel-2.6.35.3-8.1.i586.rpm&package=kernel-adaptation-intel-tv&project=MeeGo%3ATV%3Adevelop%3Adhg_sdk%3Apc21.1&repository=MeeGo_1.2>
package, it’s only exported some Makefiles and libraries. Is this the
default behavior for kernel package? (I create
kernel-adaptation-intel-tv
<http://dhgobs.sh.intel.com/package/show?package=kernel-adaptation-intel-tv&project=MeeGo%3ATV%3Adevelop%3Adhg_sdk%3Apc21.1>
based on some version from MeeGo core kernel package).
is this header upstream?
asking because otherwise you have an unofficial ABI that really ought
not to be exposed to userspace too widely.
(in fact, meego policy so far is that such evil headers must be copied
and used by the using library inside their own tarbal/package)
yes it's evil to do that, but the one package doing this will KNOW it is
evil and taking a risk, versus exposing something to a wider,
unexpecting audience.
