* kernel: set default for KERNEL_BPF_KPROBE_OVERRIDEStijn Tintel2023-03-051-0/+1
| | | | | | | | | Without the default value this still causes a missing symbol. Disable by default as it depends on FUNCTION_ERROR_INJECTION, which is disabled in the generic config and we don't have a build symbol to enable that.

* kernel: set default values for ARM low level debugging symbolsRobert Marko2023-02-081-0/+6
| | | | | | | | | | | | | | | | | | | | | Set default values for KERNEL_DEBUG_LL and KERNEL_DEBUG_LL_UART_NONE again as both of these symbols are non visible if KERNEL_EARLY_PRINTK is not selected and KConfig wont write their value to .config. This usually is the intended behaviour, but in OpenWrt we are relying on the KConfig to set these and disable the debug console settings that multiple targets like mvebu have set in their kernel config. This was the behaviour before removing all of the "default n" settings as KConfig by default considers symbols disabled but they are not visible anymore and thus their value is not set in .config and build system then later does not override the values from target kernel config. So, to restore the behaviour to the previous one lets a default value for KERNEL_DEBUG_LL and KERNEL_DEBUG_LL_UART_NONE.

* scripts/download.pl: make the download tool configurableChristian Marangi2022-10-201-0/+14
| | | | | | | | | | | | | | | | | | | | | | Introduce a new option in the "Advanced configuration options" to configure a custom download tool. By declaring a string in "Use custom download tool" an user can force what command to use to download package. With the string empty the default tool used is curl, with wget as a fallback if not available. download.pl supports 3 tools officially aria2c, curl and wget. If one of the tool is used in this config, download.pl will use the default args to make use of them. If the provided string is different than aria2c, curl or wget, the command is used as is and the download url will be appended at the end of such command. While at it also tweak the tool selection logic and chose the tool only once when the script is called and move aria2c specific variables in the relevant section.

* bcm53xx: use -falign-functions=32 for kernel compilationRafał Miłecki2022-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Northstar SoCs have pretty small CPU caches and their performance is heavily affected by cache hits & misses. It means that all kind of random code changes can affect performance as they often reorganize (change alignment & possibly reorder) kernel symbols. It was discussed in ARM / net mailinglists: 1. ARM router NAT performance affected by random/unrelated commits [1] [2] 2. Optimizing kernel compilation / alignments for network performance [3] [4] It seems that -falign-functions can be used as a partial workaround. It doesn't solve all cases (e.g. documented watchdog one [5]) but it surely helps with many of them. A complete long term solution may be PGO (profile-guided optimization) but it isn't available at this point.

| | | | | | | | | | | | | | | | | | | | Generate BTF (BPF Type Format) information from DWARF debug info. This is embedded in the kernel and exported via sysfs as /sys/kernel/btf/vmlinux. BTF data enhances kernel portability and introspection for BPF programs. Selecting this also enables the dwarves host package which provides the pahole tool used for BTF encoding. Test using: "bpftool btf dump file /sys/kernel/btf/vmlinux format c" This needs to depend on KERNEL_DEBUG_INFO_REDUCED not being set, otherwise we can enable both KERNEL_DEBUG_INFO_BTF and KERNEL_DEBUG_INFO_REDUCED, which will result in undefined behaviour.

* base-files: add option to make /var persistentStijn Tintel2021-08-221-0/+8
| | | | | | | | | | | | | | | | In OpenWrt, /var is symlinked to /tmp by default. This is done to reduce the amount of writes to the flash chip, which often have not the greatest durability. As a result, things like DHCP or UPnP lease files, are not persistent across reboots. Since OpenWrt can run on devices with more durable storage, it makes sense to have an option for a persistent /var. Add an option to make /var persistent. When enabled, /var will no longer be symlinked to /tmp, but /var/run will be symlink to /tmp/run, as it should contains only files that should not be kept during reboot. The option is off by default, to maintain the current behaviour. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
