* treewide: strip useless `default n` Kconfig linesTony Butler2023-02-031-5/+0
| | | | | | | | | | Kconfig docs say: > The default value deliberately defaults to 'n' in order to avoid > bloating the build. Apply this rule everywhere, to avoid more cloning of bad examples Signed-off-by: Tony Butler <spudz76@gmail.com>
* 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.

* tools: add option BUILD_ALL_HOST_TOOLS to compile all host toolsChristian Marangi2022-09-301-0/+7
| | | | | | | | Add option to compile all host tools even if not needed. This can be useful to prepare a universal precompiled host tools archive to use in another buildroot and speedup compilation. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
* 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.

* build: add option to mark devices as BROKENAdrian Schmutzler2020-07-301-1/+1
| | | | | | | | | | | By specifying "BROKEN := 1" or "BROKEN := y" for a device, it will be hidden (and deselected) by default. By that, it provides a stronger option to "disable" a device beyond just using DEFAULT := n. To make these devices visible, just enable the BROKEN option in developer settings as already implemented for targets and packages. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* build: improve ccache supportRoman Yeryomin2020-07-111-0/+7
| | | | | | | | | | | | | | | | | | Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR). This allows to do clean and dirclean. Cache hit rate for test build after dirclean is ~65%. If CCACHE is enabled stats are printed out at the end of building process. CCACHE_DIR config variable allows to override default, which could be useful when sharing cache with many builds. cacheclean make target allows to clean the cache. Changes from v1: - remove ccache directory using CCACHE_DIR variable - remove ccache leftovers from sdk and toolchain make files - introduce CONFIG_CCACHE_DIR variable - introduce cacheclean make target Signed-off-by: Roman Yeryomin <roman@advem.lv>
* rules: allow arbitrary log destinationPaul Spooren2019-09-291-0/+7

* build: don't add -fno-plt for ARCFelix Fietkau2016-02-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | Curent ARC toolchain fails to build libstdc++ if -fno-plt is used. Lots of following error messages appear: ------------------->8------------------ ... staging_dir/toolchain-arc_arc700_gcc-arc-2015.06_uClibc-1.0.9/arc-openwrt-linux-uclibc/bin/ld: BFD (GNU Binutils) 2.23.2 assertion fail elf32-arc.c:2786 collect2: error: ld returned 1 exit status ------------------->8------------------ In newer binutils (still in development) for ARC rewritten from scratch this seem to not happen, so once new binutils for ARC hit the street this patch might be reverted.

* config: Remove KERNEL_GIT_LOCAL_REPOSITORY optionJohn Crispin2014-06-021-8/+0
| | | | | | | | | | | | | | | | | | | | The GIT_LOCAL_REPOSITORY option adds the --reference argument to the git clone kernel command line, if KERNEL_GIT_CLONE_URI is set. This option is intended to speed-up the repo creation by using local objets rather than downloading it. However, a local repo can be cloned much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree. In that case, git clone will bypass the normal "git aware" transport mechanism and clone the repository by copying and hardlinking objects rather than downloading it, resulting in a significant speed increase. That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.
