* config: extend small_flash featureAlex Maclean2018-07-121-3/+8
| | | | | | | | | | Extend the small_flash feature to disable swap, core dumps, and kernel debug info, and change the squashfs block size to 1024KiB. Also change squashfs fragment cache to 2 for small_flash to ease memory usage. Signed-off-by: Alex Maclean <monkeh@monkeh.net>
* kernel: only optimized for size if small_flashMathias Kresin2018-07-121-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | Add a new config option to allow to select the default compile optimization level for the kernel. Select the optimization for size by default if the small_flash feature is set. Otherwise "Optimize for performance" is set. Add the small_flash feature flag to all (sub)targets which had the optimization for size in their default kernel config. Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new setting. Exceptions to the above are: - lantiq, where the optimization for size is only required for the xway_legacy subtarget but was set for the whole target - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have plenty of space and an optimization for size doesn't make much sense - rb532, which has 128MByte flash Signed-off-by: Mathias Kresin <dev@kresin.me>
* config: add config option for KERNEL_TASKSTATSJeremiah McConnell2018-07-071-0/+21
| | | | | | | | | | In order for monitoring tools such as atop and htop to track and report i/o data, kernel support for task statistics and io accounting is required. Add a config option to enable building this support in the kernel. Signed-off-by: Jeremiah McConnell <miah@miah.com>

* lantiq: ase: turn off fpu emulator in default buildYousong Zhou2018-01-291-1/+1
| | | | | | | | | | It was only enabled when the target was added back in commit 9b321bc ("lantiq: add Amazon-SE subtarget") Leave pistachio alone as devices of this target are not likely have small_flash or low_mem constraint Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>

* kernel: allow disabling multicast routing supportMatthias Schiffer2018-01-111-1/+16
| | | | | | | | Multicast routing support is not needed in most setups, and increases the size of the kernel considerably (>10K after LZMA). Add a config switch to allow disabling it. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>

* kernel: enable CRASH_DUMP on supported platformsDaniel Golle2017-05-201-0/+10
| | | | | | | While we have CRASHLOG on MIPS it makes sense to support 'classic' kexec-based CRASH_DUMP on x86 and arm platforms. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
* kernel: remove out of tree direct-io disable hackFelix Fietkau2017-04-261-4/+0
| | | | | | | Direct-IO support has to be enabled for the release build anyway, so this hack is not worth keeping Signed-off-by: Felix Fietkau <nbd@nbd.name>
* x86: disable crashlogFelix Fietkau2017-01-131-1/+1
| | | | | | | | It could cause crashes with some forms of virtualization, and it is unlikely to work properly with most systems. It's safer to just disable it. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* kernel: add KERNEL_DEVMEM and KERNEL_DEVKMEMHauke Mehrtens2016-12-241-0/+14
| | | | | | | | | These options are needed to create /dev/mem or /dev/kmem . /dev/mem is needed by the io tool to access raw hardware memory, which is helpful when debugging and developing drivers. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Acked-by: John Crispin <john@phrozen.org>

| | | | | | | | | Add the basic set of kernel options to allow it from mounting a NFS root and boot from it. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 48590
* include/kernel: add custom USER/DOMAIN config optionsFelix Fietkau2016-01-281-0/+16
| | | | | | | | | | | | | | | These allow the generated kernel's build metadata to be defined explicitly. This metadata is reported, eg, at boot time and in `uname -a` on running systems. If the variables aren't configured, the current build system username and hostname are used as normal. The motivation for this option is to achive reproducible (bit-for-bit identical) kernel builds of official openwrt releases.

* Configure IPv6 kernel options in config/Config-kernel.inFelix Fietkau2016-01-041-0/+23
| | | | | | | | | | | | | | | | | | | Revision 46834 changed IPv6 support from a module to builtin. But since the configuration of the IPv6 kernel options was left in package/kernel/linux/modules/netsupport.mk, this means that an empty kmod-ipv6 module was still being generated (not packaged). This patch moves the configuration of the IPv6 kernel options to config/Config-kernel.in to remove this last bit of the module. Note that CONFIG_IPV6_PRIVACY was dropped (enabled by default since Linux v3.13), so this option is no longer needed.

* kernel: Support kernel options required by systemdJohn Crispin2015-03-211-6/+28
| | | | | | | | | | | | | These kernel options are all likely to be widely useful in this modern age, but are immediately useful for systemd support. c.f. http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-apps/systemd/systemd-9999.ebuild?&view=markup#l118 Adapted from a patch by Adam Porter.

* kernel: enable open by fhandle syscallsJohn Crispin2015-03-151-0/+6
| | | | | | | | | | | | | | | | | | | | This is needed by many services to function properly and as all modern distributions got it enabled, it starts to be a de-facto standard, i.e. user-space starts to silently depend on it. This also pulls in EXPORTFS, however, the kernel binary size increases only a little. On ARM systems comes down to 800 bytes uncompressed and about 200 bytes compressed size. On MIPS systems it's about 1.2 kB size increase of the LZMA compressed kernel. v2: use menuconfig option instead of just enabling the option Signed-off-by: Daniel Golle <daniel@makrotopia.org> SVN-Revision: 44765
