The Linux Kernel ACPI Patch is published both as "BK trees"
on bkbits.net, and as plain patches on kernel.org.
Upon updates, e-mail is sent to email@example.com
The patches themselves are no longer distributed from sourceforge.net
BK Trees: http://linux-acpi.bkbits.net/
There are two flavors -- test and release.
The latest code is in the test trees. When it has seen some airtime,
the test trees are pulled into the release trees, which are a staging
area for pulling into the baseline kernels.
There are currently three releases:
2.4.22 is based on (frozen) v2.4.22
2.4.23 is based on (recent) 2.4.23 from http://linux.bkbits.net/linux-2.4
2.6.0 is based on (recent) 2.6.0 from http://linux.bkbits.net/linux-2.5
(Two flavors) x (3 releases) = 6 trees:
The easiest way to get a copy of the latest ACPI patch and keep it
up to date is to snag a (free) copy of bitkeeper from http://bitkeeper.com
Choose the flavor and release from above, clone it onto your drive:
$ bk clone http://linux-acpi.bkbits.net/linux-acpi-test-2.4.22 my-acpi-repo
See if new updates are available:
$ cd my-acpi-repo
$ bk changes -R
$ cd my-acpi-repo
$ bk pull
Note that the pull will refuse to update if it discovers that
you checked out files for editing that it needs to change.
So if you make local changes, you may want to "bk clone"
your acpi repository to a place where you make changes, or
"bk export" the SCCS tree to a plain source tree for modification.
You can also browse the source trees and csets on bkbits.net.
Note that it is easier to see the ACPI-specific csets by browsing
the "frozen" tree because only ACPI-specific csets are checked in
on top of the frozen kernel baseline.
Plain Patches: ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches
For the 2.4.22 and 2.6.0 test trees, individual patches are
available for each cset. These patches will stick around at
least until they're integrated into the baseline kernel.
The patch filenames begin with a date-timestamp; and should be
applied in date-timestamp order in case they depend on each other.
For the 2.4.22, 2.4.23, and 2.6.0 release trees, patches that
bundle groups of csets together are available.
The ACPI version number is generally incremented for each bundle,
and appears in the patch filename along with the name of
the release the patch applies to.
In both cases, there is a header at the top of the patch
including the BK cset comments to describe what is included
in the patch. Note you can test if a patch will apply cleanly
before you apply it for real:
$ cd my-src/linux/
$ patch --dry-run -Np1 < acpi.patch
$ patch -Np1 < acpi.patch
