* kernel: enable CONFIG_BPF_JIT by defaultTony Ambardar2019-02-111-1/+1
| | | | | | | | | | | | | | | | | | Enable the built-in BPF JIT compiler for all 4.9, 4.14 and 4.19 kernels, which should speed up cBPF and eBPF-based packet filtering (tc, iptables) and packet sniffing (libpcap, tcpdump, fwknopd, etc). This has minimal kernel size impact, increasing the size of uImage-lzma (normally ~2 MB on mips_24kc or mips64el_mips64) by 5 KB for the MIPS32 arch cBPF JIT and by 9 KB for the MIPS64 arch eBPF JIT, on kernel 4.14. With JIT enabled (cBPF only), the standard BPF test module (test_bpf.ko) running on a DIR-835 (mips_24kc) used 33 CPU seconds, but 68 without JIT. This change aligns with the notion of OpenWRT as the network go-to swiss army knife for packet handling, especially on CPU-constrained platforms. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>

* kernel: enable CONFIG_BRIDGE_VLAN_FILTERINGDaniel Golle2018-11-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows us to use the bridge as a managed switch and gracefully handle mixed tagged and untagged frames. Prior to this, the only alternative was creating one bridge per vlan which quickly becomes a nightmare and still won't let you mix both tagged and untagged frames on the physical port without some complex ebtables magic. This is in line with the notion that OpenWRT is the network go-to swiss army knife when you need a nice set-and-forget, low maintenance box to handle a specific task. Current builds of the ip-bridge package already fully support this feature so the only requirement is enabling the kernel config. This is disabled by default so existing bridge configurations will not be affected. This patch only gives the ability to turn it on with an 'ip link' command. If there is interest, I could look into making the feature accessible via uci configuration. It causes about 3.1% hit on raw bridging speed, which is relatively trivial considering that I had to use 300 byte packets to strain the CPU enough to notice a slowdown at all. The ER8 would chug along at wire speed otherwise, and that's using only one core. Since the typical bridge use case on OpenWRT is wireless, I doubt it would be noticeable at all.

* kernel: support gcc-optimized inlining on all architecturesFelix Fietkau2018-10-091-0/+1
| | | | | | | | Optimized inlining was disabled by default when gcc 4 was still relatively new. By now, all gcc versions handle this well and there seems to be no real reason to keep it x86-only. Signed-off-by: Felix Fietkau <nbd@nbd.name>

* 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 Kresin2018-07-121-2/+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: move CONFIG_USB_MTU3 to generic configHauke Mehrtens2018-07-071-0/+1
| | | | | | | | | | | CONFIG_USB_MTU3 is not visible for the mediatek target by default, but only when CONFIG_USB_GADGET is set. This will config option will be remove with when running "make kernel_oldconfig", move this option to the generic config to prevent this. This fixes the build of the mt7623 subtarget of the mediatek target. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* kernel: disable some DRM_PANEL config optionsHauke Mehrtens2018-07-071-0/+2
