How to Find and Apply the Latest Linux ACPI Patches

If you are unable to use git, you can apply the latest consolidated ACPI test branch using a plain patch:

http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/release

This directory includes patches from the Linux/ACPI git release branch. Len publishes these when he sends a pull request to Linus. If Linus doesn't pull for awhile, this patch tells you what is waiting to go upstream. As soon as Linus pulls, however, this patch becomes a duplicate of what is in Linus' tree and, thus, no longer applies.

The patches are named like this:

acpi-release-20050902-2.6.15-rc5.diff.gz

The patch above:

was created on the release branch
was created sometime after 2.6.15-rc5
includes ACPICA, up through 20050902

ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/test

The directory above includes patches from the Linux_ACPI _test_test branch, as well as other topic branches, such as ACPICA, shown below:

acpi-test-20050916-2.6.15-rc5.diff.gz
acpi-acpica-20051202-2.6.15-rc5.diff.gz

Len rarely publishes individual test patches here, because they can now be pulled from the GUI using gitweb: http://www.kernel.org/git/?p=linux/kernel/git/lenb/linux-acpi-2.6.git

Patch Signing

Files on ftp.kernel.org are compressed and signed, per http://www.kernel.org/signature.html

If you'd like to verify the signature, import the key by:
gpg --keyserver wwwkeys.pgp.net --recv-keys 0x517D0F0E verify integrity by:
gpg --verify you can skip <sigfile> if it is in the same directory as <sigfile>.

Applying Patches

Both test and release patches have a header at the top of the patch, including commit comments to describe what is included in the patch. Note that you can test whether a patch will apply cleanly before you actually apply it:

$ cd my-src/linux/

To test:
$ patch --dry-run -Np1 < acpi.patch

For real:
$ patch -Np1 < acpi.patch
