Message-Id: <1414570902-5675-1-git-send-email-mcgrof@do-not-panic.com> Date: Wed, 29 Oct 2014 01:21:38 -0700 From: "Luis R. Rodriguez" <mcgrof@...not-panic.com> To: backports@...r.kernel.org Cc: linux-kernel@...r.kernel.org, yann.morin.1998@...e.fr, mmarek@...e.cz, sassmann@...nic.de, "Luis R. Rodriguez" <mcgrof@...e.com> Subject: [RFC v2 0/4] backports: kernel integration support From: "Luis R. Rodriguez" <mcgrof@...e.com> Here's a v2 spin on the previous RFCs with a new patch added at the end that actually modifies gentree.py to add the ability to do the kernel integration magic now. If you'd like to test this get Linus' tree and reset it to some old kernel: git reset --hard v3.15 Then get linux-next and reset it to the latest supported tag: git reset --hard next-20141003o apply this series on top of that lest backports tree and then do somethine like: mcgrof@...on ~/backports (git::master)$ ./gentree.py --clean --integrate --gitdebug /home/mcgrof/linux-next/ /home/mcgrof/test-linus-tree/ The test-linus-tree in this case is a clone of Linus' tree reset to v3.15. What this will do is add the drivers that backports supports into that tree already backported for you and with tha appropriate kconfig / makefile magic done. The way we use --gitdebug is that since you are using a git tree for Linus' tree you'll see commits of each change done by the integration, this leverages off of Johannes's git debug work but applies now also nicely for integration to see each step. On 'make menuconfig' you will now see a backports menu, drivers will only be available if you do not enable them on your older kernel options. Right now things build with make M=backports and the last piece of integration with vmlinux still needs some refinement. I notice that the souce "drivers/..." on some backports/drivers/ Kconfig files didn't get modified with source "backports/drivers/..." so that needs to be fixed to populate more divers. This obviously also needs testing to ensure we don't break packaging of backports with ckmake, but we can start looking at that once we at least complete integration which hopefully shouldn't take much longer. Reminder: we should add a Kconfig entry for the LINUX_BACKPORT define symbol as part of this work as some folks dont' want to use it. Please note that this last patch was a bit sloppy but hence the RFC, figured its best to get this out for more eyeball review than hogging it up longer. Luis R.
