Glibc has a dependency on the 2.6 kenrel tree too, but that doesn't mean there is a dependency between on 2.6 kernel and another for propper user mode support.
Yes I have seen those files. They define the sys call ABI that bionic uses. There is nothing magic or tightly coupled to the specific kernel version other than you need a newer kernel than 2.4 to satisfy the assupmtions therein. All thats important is the kernel expose the kernel ABI assumed by the user mode. So far that is only: 2.6 erra sys_calls for the android libc (bionic) binder wake lock ashmem early (consol) suspend logger (i think thats all, asside from stuff thats already in the upstream kernel tree like frame buffer, audio, network, input, and a few other things you need to be sure to have enabled in your kernel config.) --mark On Sep 22, 10:38 am, Vikram <vikrampand...@gmail.com> wrote: > hi Mark > > Why do you say there is no relationship between userspace and the > kernel version? > > Did you check: > Kernel: > include/linux/.... > > and > > Android 2.2: > bionic/libc/kernel/common/linux/..... > > There are same header files shared between kernel and the filesystem. > thus introducing a dependency between filesystem and the kernel > version. > > Some script is run on kernel headers to generate the filesystem > headers and i think Android team must be doing it once every pastry > release. > > See example > header:http://android.git.kernel.org/?p=platform/bionic.git;a=blob;f=libc/ke... > 1 / > **************************************************************************** > 2 > **************************************************************************** > 3 *** > 4 *** This header was automatically generated from a Linux > kernel header > 5 *** of the same name, to make information necessary for > userspace to > 6 *** call into the kernel available to libc.
