* kernel: don't use libzstd for perfMichael Olbrich2020-02-261-0/+1
| | | | Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* kernel: disable libcap support for perfBastian Krause2020-01-121-1/+2
| | | | | | | | | In v5.4 74d5f3d06f70 ("tools build: Add capability-related feature detection") introduced libcap support. Disable it to keep perf's features consistent and the number of dependencies small. Signed-off-by: Bastian Krause <bst@pengutronix.de> Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* kernel: Replace PTXCONF_KERNEL_ARCH_STRING with GENERIC_KERNEL_ARCHSascha Hauer2019-11-241-4/+4
| | | | | | | | | | | | | | | | | | PTXCONF_KERNEL_ARCH_STRING is used for cases when for a given ptxdist architecture multiple kernel architectures exist. This only happens on more than 10 year old Kernels, it's time to remove this compatibility cruft. We can now use GENERIC_KERNEL_ARCH which has the same purpose and is used in other places already, but doesn't handle the multiple kernel architecture case. PTXCONF_KERNEL_ARCH_STRING was useful on PowerPC where the kernel architectures "ppc" and "powerpc" existed and on x86 where we had "i386" and "x86_64". These are stories from the old days, since v2.6.24 we only have "x86" for all x86 machines and since v2.6.27 we only have "powerpc" for all powerpc machines.

* dtc: always use host-dtcMichael Olbrich2019-10-291-4/+0
| | | | | | | It's the upstream, so we can always get a recent enough version. And it provides more tools that will be needed to create fit images. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
* kernel: fix builtin initramfsMichael Olbrich2019-10-181-1/+1
| | | | | | | | The path for the dummy initramfs was accidentally changes during the OOT rework. As a result, it could not be created due to a missing directly. Change it back to what it is supposed to be. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>

* rules: share the wrapper blacklist for all low-level packagesMichael Olbrich2019-09-161-8/+1
| | | | | | | | This should really be the same anyways and some packages tend to be forgotten when new options appear. So use one variable for all. This adds missing options, e.g. for the kernel template. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>

* kernel: rework prepare stageMichael Olbrich2019-02-231-15/+16
| | | | | | | | | | | | | | | | | | The old implementation is broken, when a initramfs is used. Changing the kconfig symbol back to '# Automatically set by PTXDist' is broken because '$(<)' is not the kernel config any more (Broken since cd920ab716bab0c190666e0273c10b19c7cdaeec "barebox/kernel: drop explicit dependency"). Also, world/kconfig-sync compares .config and KERNEL_CONFIG and this does not work because CONFIG_INITRAMFS_SOURCE in .config has been modified. Instead, make sure that KERNEL_CONFIG contains the path independent dummy text before copying it to .config. Then run the default prepare stage that checks or updates the config. Insert the path for the empty initramfs after all checks are done. Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de> Tested-by: Jon Ringle <jringle@gridpoint.com>

* kernel: add workaround to keep kernelconfigs stableMichael Olbrich2018-12-061-0/+5
| | | | | | | | | | With linux-4.19 and gcc-8.x oldconfig will prompt for extra options that are not available with e.g. gcc-7.x. This causes problems when a BSP is built with different host compilers. Add a workaround to optionally disable these extra options by forcing the compiler check to fail.

* kernel: cleanup ruleMichael Olbrich2018-11-101-38/+19
| | | | | | | | | | | | Use _CONF_OPT/_MAKE_OPT/_INSTALL_OPT. This makes it possible to use more of the generic build stages. KBUILD_BUILD_* is now handled by the generic build stages. Add some magic to detect external kernel modules that still use KERNEL_MAKEVARS. Drop the patch handling in clean. Patches are not applied if a local_src/ symlink is used.

| | | | | | | | | | | | | | | | | Icecc splits preprocessing and compiling.

* Debugging: add support for 'build-id'sJuergen Borleis2017-06-211-1/+2
| | | | | | | | | | | | | | | | | | | | Recent debugging tools support separate binaries and debug information files. Providing a unique 'build-id' embedded in the binary enables the debugging tools to select the correct and matching debug information files from the system's root filesystem. The 'build-id' is a 40 character calculated SHA1 from important sections in the binary. The debug information files get stored at a central direcory at "/usr/lib/debug/", with a special path based on the 'build-id'. If the 'build-id' is "123456789abcdef", the path and filename will be ".build-id/12/3456789abcdef.debug". Its possible to have more than one 'build-id' in the binary. This implementation prefers the first one in the list, which might be the wrong one. It's unclear yet how the common debugging tools will behave in this case.
