To make acking easier, it would be nice to have more information in the
commit message.

1. Reference or URL to the ID of the commit to 2.6.23.
2. What is the addition used for?
3. Has it been tested? How?

Otherwise the list seems to be pretty calm recently. I do not know how
it could be revived.


Thanks,

Paul

This got added... so NACK.

[PATCH v2] linux-libc-headers 2.6.24: backport arm/asm/hwcap.h from recent kernels

[Steffen Sledz]

This patch is similar to the one in linux-libc-headers 2.6.23 [1] and
enables building of OpenJDK which uses HWCAP_THUMBEE which normally
are not present in 2.6.24 headers.

header, please [1].

Marcin, can you write something to this? I just adapted your patch to the 2.6.24 headers.

In BugLabs we used Poky 'pinky' and then switched to OpenEmbedded
2009-stable tree. At that time we used 2.6.2x linux-libc-headers as this
was present in both trees and selected by default.

When BUG 2.0 prototypes started working we started move from phoneme to
openjdk as java-vm provider. To build openjdk newer linux-libc-headers
were needed due to lack of HWCAP_THUMBEE define in 2.6.2x ones. Patching
default version was better solution then switching to newer one as it
gave us smaller chance of build failures.

And that's whole story of it.

Looking at your patch and the relevant Linux kernel commits, I do not
see how this can come from mainline Linux.

            [ARM] 5388/1: Add hwcap bits for VFPv3 and VFPv3D16

After figuring that out I would just put these commit messages excerpts
into the patch header.

By the way, the Linux kernel version the last patch was merged is
therefore 2.6.30.

        $ git describe --contains 7279dc3e
        v2.6.30-rc1~636^2~52^2~24

So the commit summary could be updated to be more specific.

Dear Steffen,


unfortunately I still have something to add. :(

1. Please do not use `recent` but write the correct version. In this
case it would be 2.6.26 (see below).

2. Of course that is not correct and I asked that in my last response
why a move should introduce new code lines.

Using

        git log --follow 4baa9922430662431231ac637adedddbb0cfb2d7 -- arch/arm/include/asm/hwcap.h

I found the following commit

Please note that this commit contains not only the addition of
HWCAP_THUMBEE to the header but a lot more. So is OpenJDK doing
something incorrectly then? Does it detect the wrong architecture?

Please update the relevant parts and send it to the list again. You can
commit it the next day if nobody else objects.

PS: It is hard for reviewers to see what changed in your patch
iterations. For example between v3 and v4. Please add a short note below

Is it possible to add such a comment while running "git format-patch" or "git send-email"?

Or is it necessary to mix this into the commit comment itself?

I do not know of a way and I did not find anything in the manual. I
guess you have to edit the mbox file created by `git format-patch` and
then send it.

Other people also use the cover letter feature. But in all cases it
seems to be one step more.

> Or is it necessary to mix this into the commit comment itself?

No, since `git push` is not leaving the comment out.

Thank you again for addressing my comments.

Paul

After reading the manual i found the --annotate option for "git send-email" which helped me here.
