17 Here you will find options to configure the kernel.
19 SDECFG_PKG_LINUX_CUSTCONFIG
20 Here you can define custom configurations to the kernel.
21 Please note that these will apply _after_ the default kernel config
24 SDECFG_PKG_LINUX_CONFIG_STYLE
25 This options selects whether to not perform an automated kernel
26 configuration generation, to parse the normal ROCK Linux configuraton
27 templates or to perform the normal parsing and additionally enable all
28 modules (the default setting).
30 The first option - to disable the configuration - is useful if you want
31 to supply a full configuration in config/$id/linux.cfg.
33 Manually supplied kernel config options will be applied whatever option
36 SDECFG_PKG_LINUX_KEEP_SRC
37 Select this option if you want the get a copy of the kernel sources
38 installed into /usr/src/ after the kernel build.
40 If you want to debug or develop on the kernel or tinker with alternative
41 config option you probably want to enable this option.
43 SDECFG_PKG_LINUX_USE26MODTOOLS
44 Select this option if you want to use the newer module utils. This is
45 required for 2.5/2.6++ kernel.
47 Compatibility with former 2.4-- kernels will be retained if the old
48 modutils are build as well (they install with a .old postfix.
50 SDECFG_PKG_LINUX_UML_STYLE
51 Here you can define UML (User Mode Linux) specific kernel optimizations.
55 * none -> Do not perform any automatic UML related optimization.
57 * skas3 -> Build UML Host kernel with SKAS3 support.
59 If this option is choosed the linux kernel will be automatically patched with
60 the SKAS3 host patch, which will increase the speed while running a UML
61 instance. If you need to run a lot of UML instances you should try to enable
64 * guest -> Build UML Guest kernel.
66 If this option is choosed the linux kernel will be build as UML Guest kernel.
69 Further information regarding UML and SKAS3 patch can be found here:

73 SDECFG_PKG_LINUX_ACPI_INITRD
74 A custom DSDT (Differentiated System Description Table) is useful when your
75 computer uses ACPI but problems occur due to a broken implementation. With this
76 option the kernel is modified so that a custom DSDT is loaded from initramfs
78 If mkinitrd detects a file "/DSDT.aml" or "/boot/DSDT.aml" it will be
79 automatically added to the initramfs. Alternatively you may use the command
80 initrd-add-dsdt to add it manually.
