When applied my last patch to 1.3.27 for a kernel config menu, you can
upgrade to 1.3.28 with only one failed hunk which is my fault since I
did a change in my last patch which was in pre-patch-1.3.28. Then, this hunk
was already applied, and you can ignore the reject.
I've included is a patch for a linux-1.3.28 with has the last 'make
menuconfing'-patch already applied.
With linux-1.3.28, Linus added the new dep_tristate function to the
kernel configuration, which I implemented in this patch to be useable
with version 1.3.28 and above.
This new function is used along with the new ability to load the entrie
SCSI subsystem as a module. When the subsystem is a module, it's cleary
not possible to link the SCSI-drivers into the kernel. Showing this is
the aim of the function.
It was real fun for me to implement it, and now it's ready with a nice
whistle:
For example, if you change SCSI to a module, it presents you with the
settings which depend on SCSI and offers you to load it as a module or
even not use it.
Here is an example of this:
[p1]08:18:15/usr/src/linux# make menuconfig
rm -f include/asm
( cd include ; ln -sf asm-i386 asm)
/bin/sh scripts/Configure.menu arch/i386/config.in
Loading .config
Please wait, building menus............
Linux Kernel Configuration
1: General setup
2: Loadable module support
3: Networking options
4: SCSI support
5: SCSI low-level drivers
6: Network device support
7: CD-ROM drivers (not for SCSI or IDE/ATAPI drives)
8: Filesystems
9: character devices
10: Sound
11: Kernel hacking
12: Configure sound driver
w: write kernel setup to disk and exit
l: load setup from a file saved by `s'
s: save setup to a file for later use
q: quit without saving changes
Enter a option, [wlsq] or `r' to redisplay the menu.
option: 4
Menu: SCSI support
1: [Y] SCSI support
SCSI support type (disk, tape, CDrom)
2: [Y] SCSI disk support
3: [M] SCSI tape support
4: [Y] SCSI CDROM support
5: [ ] SCSI generic support
Some SCSI devices (e.g. CD jukebox) support multiple LUNs
6: [ ] Probe all LUNs on each SCSI device
b: back to the main menu
Enter a option, [wlsq] or `r' to redisplay the menu.
option: 1
SCSI support (CONFIG_SCSI) [Y/m/n] m
Hmm, choose a new setting...
SCSI disk support (CONFIG_BLK_DEV_SD) [M/n] m
Hmm, choose a new setting...
SCSI CDROM support (CONFIG_BLK_DEV_SR) [M/n]
Hmm, choose a new setting...
Adaptec AHA1542 support (CONFIG_SCSI_AHA1542) [M/n] n
Menu: SCSI support
1: [M] SCSI support
SCSI support type (disk, tape, CDrom)
2: [M] SCSI disk support
3: [ ] SCSI tape support
4: [M] SCSI CDROM support
5: [ ] SCSI generic support
Some SCSI devices (e.g. CD jukebox) support multiple LUNs
6: [ ] Probe all LUNs on each SCSI device
b: back to the main menu
Enter a option, [wlsq] or `r' to redisplay the menu.
option: w
write new setup and quit ? [n] y
The linux kernel is now hopefully configured for your setup.
Check the top-level Makefile for additional configuration,
and do a 'make dep ; make clean' if you want to be sure all
the files are correctly re-made
------------------------------------------
This does things I have newer thought of, and it's a nice hack too. :-)
Here is the patch mentioned above, any comments are welcome.
It's a crazy script, but it work's like a charm.
