Android's git Repository

***

a public git repository put together with the 
various android-specific kernel patches (binder, logger, alarm drivers,
goldflish platform support, etc) soon. 

Which HW support

We're trying to use the standard kernel/driver interfaces when possible,
but for things that may have a good deal of variation in implementation,
we're looking to provide a very thin "hardware interface library" layer
to adapt between the bottom of the userspace stack and the drivers or
whatnot for specific hardware platforms.  

We'll continue to adopt standardized kernel solutions as they become
available -- We're now using the power supply framework in 2.6.24 for
monitoring battery/charge state (post M5 SDK -- it'll be in the next 
release), for example.

Okay. I sent my 2.6.23 omap1 Android patch yesterday (seems that it 
didn't reach the list cause of > 100k). If you didn't get it I can 
send it again in private mail. Would be quite nice if you could check 
if there are the same files in it you used.

Anything like

cat my_patch | grep +++ > file1
cat your_patch | grep +++ > file2
kdiff3 file1 file2

As already mentioned yesterday: Same to me ;)

Anybody with ~30-40 MB permanent public storage?

The core android kernel patches are now available from git.android.com.
Please be aware that these are *newer* than the M5 SDK, and I think
the binder driver in particular may not be compatible with M5.  When
the next SDK release happens, we should be able to point at a sha1
hash of the git change the kernel came from.

Please note that for legacy reasons the default branch is the
msm-2.6.24 branch -- you'll want to check out the "android"
branch if you're looking for the generic patches useful for
all platforms.
