Applying patches to the Debian kernel tree
|
||
|
|
==========================================
|
||
|
|
|
||
|
|
The Debian kernel packaging uses a custom patching system:
|
||
|
|
|
||
|
|
Patches are stored below debian/patches, loosely sorted in bugfix/,
|
||
|
|
features/ and debian/. Patches are in the standard kernel patch
|
||
|
|
format.
|
||
|
|
|
||
|
|
The order and the selection of patches which are applied during build
|
||
|
|
time are specified in the series/ subdirectory. For each revision
|
||
|
|
there may be up to one file named REVISION specifying the patches
|
||
|
|
applied for the standard revision and one file named REVISION-extra
|
||
|
|
for addon flavours. If, e.g. the patches are specified for 2.6.26-12,
|
||
|
|
the patch order file is called debian/patches/series/12 for the
|
||
|
|
standard kernel images and debian/patches/series/12-extra for the
|
||
|
|
addon flavours.
|
||
|
|
|
||
|
|
Let's look at the actual series file for 2.6.26-12:
|
||
|
|
|
||
|
|
+ bugfix/all/net-unix-gc-fix-soft-lockups-oom-issues.patch
|
||
|
|
+ bugfix/all/inotify-watch-removal-umount-races.patch
|
||
|
|
+ bugfix/all/atm-duplicate-listen-on-socket-corrupts-the-vcc-table.patch
|
||
|
|
+ bugfix/all/ata-pata_marvell-vs-ahci.patch
|
||
|
|
+ features/sparc/video-sunxvr500-intergraph.patch
|
||
|
|
|
||
|
|
The patches to be applied are specified relative to debian/patches.
|
||
|
|
"+" indicates that the patch should be added, "-" can be used to
|
||
|
|
drop a patch in later patch series (e.g. if the patch turned out to
|
||
|
|
be faulty). The series files may be arbitrarily documented with
|
||
|
|
comments starting with "#".
|
||
|
|
|
||
|
|
Let's now have a look at the series file for the addon kernel flavours
|
||
|
|
of 2.6.26-12:
|
||
|
|
|
||
|
|
+ features/all/xen/dom0-fix-processor-throttling-when-pr-id-is-minus-1.patch featureset=xen
|
||
|
|
|
||
|
|
The same syntax applies for specifing the patches, but an additional
|
||
|
|
argument is needed which specifies the featureset the patch applies to.
