* kernel: enable memory compactionFelix Fietkau2018-10-091-0/+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>

* kernel: add missing ARM64_SSBD symbolStijn Tintel2018-07-311-0/+1
| | | | | | | | | In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for ARM64. Add this symbol to all ARM64 targets using kernel 4.14. This mitigates CVE-2018-3639 on ARM64. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* arm64: enable harden branch predictorMathias Kresin2018-04-271-0/+2
| | | | | | Enable the harden branch predictor for arm64 as it is recommend. Signed-off-by: Mathias Kresin <dev@kresin.me>
* armvirt: Resync kernel configurationFlorian Fainelli2018-01-121-107/+36
| | | | | | | | The 4.14 kernel configuration defaulted to a v4/v5 multiplatform while 4.9 was using a v6/v7 default configuration. Resync 4.14 against 4.9 so they are nearly identical. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
* armvirt: re-enable VFP supportJo-Philipp Wich2018-01-101-1/+0
| | | | | | | | | | Enable CONFIG_VFP again which was disabled during the 4.9 -> 4.14 bump. Boot tested both 32 and 64 bit subtargets using initramfs images with the qemu-system-arm and qemu-system-aarch64 emulators.

* kernel: move CONFIG_KASAN to generic configStijn Tintel2018-01-021-1/+0
| | | | | | | | | | While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN symbol. Move it to generic config instead of defining it for all arm64 and x86/64 targets. It was only added in 4.0, so not needed in config-3.18. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

* armvirt: Enable CONFIG_ARM_PMUFlorian Fainelli2017-09-161-0/+1
| | | | | | | We will be prompted with this config symbol when performance monitoring is enabled in the kernel. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
* kernel: cleanup CONFIG_SCHED_HRTICKStijn Tintel2017-06-291-1/+0
| | | | | | | Remove CONFIG_SCHED_HRTICK from target configs, as it was added to the generic config in b47fd7656336162360ebf66147326763ddae3f8d. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* armvirt: rename config-default to config-4.9Stijn Tintel2017-06-291-0/+0
| | | | | | | | The kernel configs for all targets should have the version in the filename, for clearness and consistency across all targets. It is also expected by the update_kernel.sh script. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
* armvirt: 64: enable usb supportYousong Zhou2017-05-032-1/+1
| | | | | | | | | It was originally only enabled for the "32" subtarget along with the "usb" feature which is now also shared by the "64" target This should fix the phase1 build of armvirt/64 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
* armvirt: merge arm64 as subtarget 64Yousong Zhou2017-04-238-118/+320
| | | | | | | | | | | | | | | | | | | | Original armvirt target is now subtarget 32. Other than that the built result should remain the same as before Besides old features already available with arm64, the new armvirt/64 subtarget will also have those features originally enabled for armvirt/32 with commit 44ecfc2 ("armvirt: new target") - pl011, uart - pl031, rtc - pl061, gpio - pci-host-generic - virtio_{mmio,pci,net,blk,scsi,9p,console,balloon} - smp with NR_CPUS=4 - cpu-hotplug - ext4 - DEBUG_BUGVERBOSE for debug purposes Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com>
