package/linux: fix custom dts files handling

2018-04-09T16:01:27+00:00

Custom dts files are still conditionally copied based on non existing boolean. So it is currently not possible to use custom dts file(s) at all. List of dts files is now iterated and files are copied into dedicated kernel arch dir.

linux: add BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF

2018-03-30T16:59:16+00:00

Some Linux kernel configuration options (such as CONFIG_UNWINDER_ORC) require building a host program that needs libelf. Users who have libelf installed on their system won't see a problem, but users who don't have libelf installed will get a build failure. Therefore, this commit adds an option that allows a user to indicate that his Linux kernel configuration requires libelf. When this option is enabled, we add host-elfutils to the dependencies of the linux package (host-elfutils provides the libelf library).

linux: add BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL

2018-03-30T16:59:03+00:00

Some Linux kernel configuration options (such as CONFIG_SYSTEM_TRUSTED_KEYRING) require building a host program called extract-cert, which itself needs OpenSSL. Users having OpenSSL installed on their system won't see a problem, but users who don't have OpenSSL installed will get a build failure. This commit adds a new option that allows users to indicate that their Linux configuration requires building host-openssl.

linux: fix passing of host CFLAGS and LDFLAGS

2018-03-30T16:58:31+00:00

We were passing HOSTCFLAGS="$(HOSTCFLAGS)" to Linux. However: - HOSTCFLAGS in Buildroot doesn't exist, and is empty, so this assignment never did anything. The name of the variable in Buildroot in HOST_CFLAGS. - HOSTCFLAGS in Linux isn't used everywhere, and passing it overrides the default HOSTCFLAGS value defined in the main Linux kernel Makefile. In addition, there is no way to pass additional host LDFLAGS in the Linux kernel build system. Therefore, we simply shoehorn our HOST_CFLAGS and HOST_LDFLAGS while passing HOSTCC to the Linux kernel build system. This has been tested to work fine with host OpenSSL and host libelf only available in $(HOST_DIR).

package/linux: drop useless intermediate DTS booleans

2018-03-30T16:46:55+00:00

Just use whatever the user specified in the list. An empty list means no DTS was specified. No need to add legacy option, as the behaviour does not change. Signed-off-by: "Yann E.

linux: allow both in-tree and custom dts files

2018-03-30T16:45:51+00:00

For some boards, for example the Raspberry Pi, it's necessary to build in-tree dts files as well as custom/out of tree dts-files (dt-blob.bin). The existing logic made these two options exclusive, this commit changes that to allow both in-tree as well as custom sources for dts files.

linux: meddle not in the internals of filesystems

2017-11-30T10:49:07+00:00

Currently, the rule to rebuild the Linux kernel with an initramfs directly depends on the path of the file of the intermediate cpio image. This is inherently "bad" from a purity point of view; linux.mk should not have to delve into the fs internals. Rather, make it directly depend on the "frontal" rule that generates the cpio image. Drop the comment for linux-rebuild-with-initramfs, it was misleading (talking about generating "the initramfs list of files", which is not what was done, since we use a cpio as source of initramfs, not a list of files).

linux: Deselect all unconfigured compression options

2017-10-21T18:20:45+00:00

The LINUX_KCONFIG_FIXUP_CMDS are meant to deselect any compression option that are not selected in the buildroot configuration. But it only deselects the last one in the list instead of all of them because it overwrites the LINUX_COMPRESSION_OPT_ variable instead of appending to it. Only the last option set to that variable gets deselected. This produces the warning: .config:2216:warning: override: KERNEL_GZIP changes choice state is emitted when buildroot runs olddefconfig when buildroot configures a kernel with a custom config that has a different kernel compression option set to what is configured in buildroot. Accumulate all the deselected compression options instead of overwriting them to ensure all non-selected options get deselected.. Signed-off-by: Cam Hutchison Reviewed-by: "Yann E.
