* kernel: enable memory compactionFelix Fietkau2018-10-091-1/+1
| | | | | | | | | | | Compaction is the only memory management component to form high order (larger physically contiguous) memory blocks reliably. The page allocator relies on compaction heavily and the lack of the feature can lead to unexpected OOM killer invocations for high order memory requests. You shouldn't disable this option unless there really is a strong reason for it. Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Michal Hrusecky <michal.hrusecky@nic.cz>
* config: extend small_flash featureAlex Maclean2018-07-121-1/+1
| | | | | | | | | | 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 Kresin2018-07-121-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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>
* kernel: Restrict dmesg output to root.Rosen Penev2018-04-301-1/+1
| | | | | | | | In typical OpenWrt setups, there are no other users that have a shell spawned for them by default. This can be overriden by the kernel.dmesg_output syssctl. Signed-off-by: Rosen Penev <rosenp@gmail.com>
* kernel: mtdsplit: Add support for D-link JBOOTPawel Dembicki2018-02-111-0/+1
| | | | | | | | | The D-Link devices with JBOOT bootloader use their own kernel image header (stag + sch2 headers). This driver find jImage header and set rootfs start after kernel file. Signed-off-by: Pawel Dembicki <paweldembicki@gmail.com>
* kernel: allow disabling multicast routing supportMatthias Schiffer2018-01-111-1/+1
| | | | | | | | 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 fadvise on older kernels.Rosen Penev2017-11-171-1/+1

* kernel: remove ubifs xz decompression supportFelix Fietkau2017-01-091-1/+0
| | | | | | | It has been unused, and less useful than squashfs for cases where flash space usage matters. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* kernel: enable pcryptJason A. Donenfeld2016-11-161-1/+1
| | | | | | | | | This is a powerful API for parallel crypto from which many other modules can benefit. It only winds up being turned on on SMP systems, which means this adds 0 bytes to the kernel on tiny machines, while only adding a small bit to SMP systems for big performance improvements.

| | | | | | | | | This allows splitting EVA images (usually found in fritz devices). The firmware will be split into a kernel and a separate rootfs partition. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> SVN-Revision: 48262
* kernel: mtdsplit: add support for brnImagesFelix Fietkau2016-01-171-0/+1
| | | | | | | | | | | | | | | | | This adds brnImage (used with the brnboot bootloader) firmware parsing support. brnboot verifies the integrity of the firmware stored on the "Code Image" partitions by looking at the 12 byte footer at the very end of the partition. This footer contains the checksum of the original brnImage (kernel + rootfs/squashfs) and must not be touched (by our JFFS2 rootfs_data - otherwise the image will not be bootable anymore). Big thanks to Mathias Kresin for analyzing the brnImage structure and finding out the information how to keep images valid even when adding a nested rootfs_data partition.
