build: cache kernel module package compiling

2023-10-28T19:34:20Z

Kernel module packages compiling is not cached (e.g. mac80211) even with CONFIG_CCACHE on. CC should be set to KERNEL_CC in KERNEL_MAKE_FLAGS at kernel.mk to allow kernel module packages using ccache. Signed-off-by: Zeyu Dong

image: Fix the CONFIG_EXTERNAL_CPIO logic

2023-10-24T11:13:59Z

Fix the qstrip call. Fixes: #13776. Signed-off-by: Luca Barbato

kernel: add CONFIG_INITRAMFS_PRESERVE_MTIME config to Initramfs function

2023-05-22T20:28:18Z

New kernel version 6.1 introduced new INITRAMFS option. Add them to the Initramfs functions to correctly compile initramfs images. Signed-off-by: Christian Marangi

build: revert 54070a1 (all kernels are >= 5.10)

2023-05-21T12:25:52Z

Commit 54070a1 was added to allow building proper SDKs with kernels < 5.10. Now that all targets use at least kernel 5.10 it can be reverted. Signed-off-by: Sebastian Kemper

build: fix incorrect initramfs gzip compression

2023-04-18T11:57:48Z

Requires: tools/libdeflate fix consistency of executable to use `$(STAGING_DIR_HOST)/bin/libdeflate-gzip`, and not system-installed ones from the usual environment `PATH`; this affects option `CONFIG_KERNEL_INITRAMFS_COMPRESSION_GZIP` this may have worked in the past but only via side effect of having the binaries on the host system (and whatever unpredictable version or patchset those might be), and did not use the improved but totally compatible libdeflate-gzip Fixes: 330bd380e8b6 ("image: allow building FIT and uImage with ramdisk") Signed-off-by: Tony Butler

build: fix incorrect initramfs bzip2 compression

2023-04-18T11:57:47Z

Requires: tools/bzip2 fix consistency of executable to use `$(STAGING_DIR_HOST)/bin/bzip2`, and not system-installed ones from the usual environment `PATH`; this affects option `CONFIG_KERNEL_INITRAMFS_COMPRESSION_BZIP2` this may have worked in the past but only via side effect of having the binaries on the host system (and whatever unpredictable version or patchset those might be) Fixes: 330bd380e8b6 ("image: allow building FIT and uImage with ramdisk") Signed-off-by: Tony Butler

include: use libdeflate's gzip to decompress

2023-01-17T20:40:18Z

libdeflate decompresses much faster than gzip.

build: fix incomplete initramfs compression options

2023-01-17T00:16:35Z

Requires: tools/lz4, tools/lzop complete the wiring so that these options work: * `CONFIG_KERNEL_INITRAMFS_COMPRESSION_LZO` * `CONFIG_KERNEL_INITRAMFS_COMPRESSION_LZ4` Signed-off-by: Tony Butler [remove blocking dependencies for separate ramdisk, fix lzop options] Signed-off-by: Daniel Golle

uml: headers are not exportable

2022-09-24T21:52:14Z

When building UML this showed up as of late (2022-09-01): | Makefile:1335: *** Headers not exportable for UML. Stop. This message popped up because of an upstream patch that fixed this error not showing up sooner. For more information see: Now, I don't think we can just skip the kernel headers. Some userspace applications are going to need these. So, The next best alternative I can think of, is to go with the headers by the host arch the UML is compiled for. (Technically, ARCH= should be safe for all other targets as well... But let's not poke a hornet's nest) Signed-off-by: Christian Lamparter

kernel: set SOURCE_DATE_EPOCH for initramfs root dir

2022-04-06T11:20:26Z

Make sure the timestamp of the root directory of the initramfs is set to SOURCE_DATE_EPOCH as well. Fixes: 29d7461d11 ("kernel: set options to make external initramfs reproducible") Signed-off-by: Daniel Golle
