* linux: add fbtft kernel extensionGravatar Peter Seiderer2015-01-101-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Tested with RaspberryPi B+ and PiTFT Mini Kit - 320x240 2.8" TFT (see [1] and [2]) and the following target configuration changes: - cmdline.txt: add 'fbcon=map:10 fbcon=font:VGA8x8' - add /etc/modules-load.d/fbtft.conf with 'fbtft_device' - add /etc/modprobe.d/00-fbtft.conf with 'options fbtft_device name=adafruit28 rotate=90 gpios=dc:25' [1] http://h65951.serverkompetenz.net/PeterSeiderer/upload/PiTFT_2_8_ct/Image9893.jpg [2] http://h65951.serverkompetenz.net/PeterSeiderer/upload/PiTFT_2_8_ct/Image9897.jpg [Thomas: - Rename prompt of the Linux extension to "FB TFT drivers" - Remove the full name of the kernel config options in the help text. Giving their CONFIG_<foo> name is enough. - Remove the mention of CONFIG_SPI_BCM2708, since this makes the description RaspberryPi specific, while these drivers can work with any SPI controller. - Refactor the code in linux-ext-fbtft.mk to avoid duplication between the < 3.15 and >= 3.15 cases. - Make the fbtft package a promptless package, since there is no point in selecting only this package, without the kernel extension. - Change the license to GPLv2, since it's kernel code.] Signed-off-by: Peter Seiderer <ps.report@gmx.net> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
* Config.in files: whitespace cleanupGravatar Thomas De Schampheleire2013-11-111-8/+8
| | | | | | | | | | This patch fixes the following whitespace problems in Config.in files: - trailing whitespace - spaces instead of tabs for indentation - help text not indented with tab + 2 spaces Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
* Config.in files: add missing dependencies to toolchain option commentsGravatar Thomas De Schampheleire2013-11-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a package A depends on config option B and toolchain option C, then the comment that is given when C is not fulfilled should also depend on B. For example: config BR2_PACKAGE_A depends on BR2_B depends on BR2_LARGEFILE depends on BR2_WCHAR comment "A needs a toolchain w/ largefile, wchar" depends on !BR2_LARGEFILE || !BR2_WCHAR This comment should actually be: comment "A needs a toolchain w/ largefile, wchar" depends on BR2_B depends on !BR2_LARGEFILE || !BR2_WCHAR or if possible (typically when B is a package config option declared in that same Config.in file): if BR2_B comment "A needs a toolchain w/ largefile, wchar" depends on !BR2_LARGEFILE || !BR2_WCHAR [other config options depending on B] endif Otherwise, the comment would be visible even though the other dependencies are not met. This patch adds such missing dependencies, and changes existing such dependencies from depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC to depends on BR2_BASE_DEP depends on !BR2_TOOLCHAIN_USES_GLIBC so that (positive) base dependencies are separate from the (negative) toolchain dependencies. This strategy makes it easier to write such comments (because one can simply copy the base dependency from the actual package config option), but also avoids complex and long boolean expressions.

* ocf-linux: remove extension and build out of treeGravatar Gustavo Zacarias2013-05-051-12/+0
| | | | | | | | | | | | | Remove the OCF linux kernel extension instead opting to build ocf-linux modules out of tree. This is easier for users since no kernel config tweaking is required. On the downside the OCF drivers can't be used, but then all of the kernel crypto drivers are available to users via cryptosoft which is preferred. Also remove it from the menu to utilize a virtual.

* Add xenomai real-time Framework to buildrootGravatar Thomas De Schampheleire2011-09-181-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Fixes by Thomas, including comments from Arnout: * Use AUTOTARGETS instead of GENTARGETS * Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the prepare-kernel.sh script. This allows the arch name to be fixed with the usual sed expressions and the quotes to be stripped. * Add the --verbose option to prepare-kernel.sh. This allows to get some clear error message when no Xenomai patch has been found for the current kernel version. * Improve the help texts as suggested by Arnout, and remove the now useless README file. * Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the kernel configuration to find out whether SMP is enabled or not. This cannot work because: 1) the kernel might be built outside of Buildroot and 2) if the kernel is built inside Buildroot, it is built *after* Xenomai, so the kernel configuration file is typically not yet present. * Simplify the ARM subarchitecture selection as suggested by Arnout. * Remove the documentation and development files according to Buildroot standards (using BR2_HAVE_DOCUMENTATION and BR2_HAVE_DEVFILES). * Simplify the /etc/ld.so.conf modification logic. ] [Peter: whitespace fixes] Signed-off-by: Benoit Mauduit <benoit.mauduit@openwide.fr> Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* linux: Add Linux Kernel extensions menuGravatar Thomas De Schampheleire2011-09-181-0/+3
Add a kernel sub-menu (called "Linux Kernel Extensions"), which makes possible to patch it or tweak the kernel build step. * All linux/linux-ext-*.mk files will be read by the make process. * The menu can be customized in "linux/Config.ext.in".
