By this time I have reworked the update of scripts/generate-kernel-patch'>scripts/generate-kernel-patch.
These are the changes that were already present in version 1 of this patch
and that have been kept in this patch:
- The SCST code has been moved from drivers/scsi/scsi_tgt to drivers/scst.
- Moved SCST header files from include/scsi_tgt to include/scst.
- Added iscsi-scst in drivers/scst/iscsi-scst.
For the time being the generate-kernel-patch does no longer try to add the
qla2x00t driver in drivers/scst/qla2x00-target -- I have not yet been able to
figure out how to get qla2x00t/qla2x00-target compiled without the initiator
code.
Just as in version 1 of this patch, the following files in the Subversion
repository have been renamed to reflect the above changes:
- Renamed scst/kernel/in-tree/Makefile.scsi.Linux-2.6.24.patch'>scst/kernel/in-tree/Makefile.scsi.Linux-2.6.24.patch to
scst/kernel/in-tree/Makefile.drivers.Linux-2.6.24.patch'>scst/kernel/in-tree/Makefile.drivers.Linux-2.6.24.patch.
- Renamed Kconfig'>scst/kernel/in-tree/Kconfig.scsi.Linux-2.6.24.patch to
scst/kernel/in-tree/Kconfig.drivers.Linux-2.6.24.patch'>scst/kernel/in-tree/Kconfig.drivers.Linux-2.6.24.patch.
- Renamed scst/kernel/in-tree/Makefile.scsi_tgt'>scst/kernel/in-tree/Makefile.scsi_tgt to
scst/kernel/in-tree/Makefile.scst'>scst/kernel/in-tree/Makefile.scst.
- Renamed scst/kernel/in-tree/Kconfig.scsi_tgt'>scst/kernel/in-tree/Kconfig.scsi_tgt to
scst/kernel/in-tree/Kconfig.scst'>scst/kernel/in-tree/Kconfig.scst.
Because of the above changes the include path specified in the following
Makefiles had to be changed:
- scst/kernel/in-tree/Makefile.dev_handlers'>scst/kernel/in-tree/Makefile.dev_handlers
- srpt/src/Makefile.in_kernel'>srpt/src/Makefile.in_kernel
Other changes:
- I have added menu/endmenu entries in file scst/kernel/in-tree/Kconfig.scst
such that the SCST entries become visible when running make xconfig or make
menuconfig.
- Elaborated the SCST help texts a little bit (in file
scst/kernel/in-tree/Kconfig.scst).
New in version 2 of this patch:
- Moved remaining patches in the generate-kernel-patch script to separate
files.
- Added support for the 2.6.25 kernel.
This patch has been tested as follows:
mkdir -p tmp
cd tmp
rm -rf linux-2.6.25.3 /lib/modules/2.6.25.3-scst
tar xjf ~vanasscb/software/downloads/linux-2.6.25.3.tar.bz2

cp ../.config-2.6.25 .
(cd ~vanasscb/software/scst
&& ~vanasscb/software/scst/scripts/generate-kernel-patch \
2.6.25) | patch -p1
make oldconfig
diff ../.config .
make xconfig
make menuconfig
make -j5 bzImage modules
make modules_install install
cp -r /lib/firmware/$(uname -r) /lib/firmware/2.6.25.3-scst
update-initramfs -k 2.6.25.3-scst -c
reboot
modprobe iscsi-scst
modprobe ib_srpt
lsmod | grep -E 'scst|ib_srpt'
