2022-02-20kernel_definitions: Remove duplicate generate_defconfig command.HEADsugisawaAdithya R
* its already present in gki guard configuration, so this one is redundant and breaks build in some cases Change-Id: I97480ea18c30a4fae1cc6e298f3333b9fa9a6321
2022-01-13kernel/build: Compile kernel as user always.Alexander Koskovich
* We should never want DebugFS brought in, and we force user for other kernel drivers like QCACLD. Change-Id: I7f77095379678f8b975fc6da106846431aa2bdb8
2022-01-13kernel/build: Fix path overrides.Alexander Koskovich

2022-01-13kernelscripts: Fix module build support.Anay Wadhera
Change-Id: Iaebe95c89bad68e69a7cf79fe9faa7b3a84149c4
2022-01-13kernelscripts: define CC variable.Jake Weinstein
* CAF's script expects this kernel commit to be present: "scripts: gcc-wrapper: Use wrapper to check compiler warnings". In some cases, it is reverted or not present, which causes compile to try to use GCC 4.9 unsuccessfully without this commit. * Since we build with -Werror anyway, this commit is safe because gcc-wrapper is redundant. Google also reverts the same CAF commit. * Vishalcj17 : Adapt for lahaina scripts. Change-Id: Ie172be870737b7960eb3fc595f51e31e753992ed

2022-01-13kernelscripts: Remove extra definitions in DTC_EXT.Anay Wadhera
* This breaks compile if the builder has specified an outdir other than out/ * This was likely a result of trying to get an absolute path for outdirs == out/ but there are better ways to do this Change-Id: Ie4df500db3ad8d3233062dfbde5f648428e67553
2022-01-13kernel_definitions: Point to AOSP build tools.Alexander Koskovich

2021-05-24kernelscripts: Add defconfig support for 32 bit targetsNagireddy Annem
Add support to generate defconfig for 32 bit targets. Change-Id: I55c560a97e249d1bb0f0e7c80055545d4ac795ca
2021-03-23kernel/build: Optimize no-change incremental kernel buildJeevan Shriram
1. Save and revert the timestamp of KERNEL_USR to the creation of kheaders file to avoid re-compilation of external/vendor modules during no-operation incremental build due to dependency on KERNEL_USR rule. 2.Avoid deletion and re-creation of the symlink in the KERNEL_OUT rule. 3. De-couple KERNEL_USR timestamp from KERNEL_OUT and KENREL_HEADERS_INSTALL target rules. Change-Id: Iea00cdd05477e767bfcab2eb489c4c70e65907c2
2021-01-06kernel_definitions: Add kernel dependency for ramdisk modulesRaghavendra Rao Ananta
Add kernel build dependency for ramdisk modules for the ramdisk packaging to wait until the kernel is built completely. Change-Id: I210793b6b4a64b658db2f23cb6a986dee50427ad Signed-off-by: Raghavendra Rao Ananta <rananta@codeaurora.org>
2020-11-03kernel_definitions.mk: Remove setting of BOARD_KERNEL_BINARIESRaghavendra Rao Ananta
Remove setting of BOARD_KERNEL_BINARIES as Android-S doesn't allow seeting this 'make' target from kernel_definitions.mk. Change-Id: I394bc83a3f13663afc69422ae77d1133e2f4e2eb Signed-off-by: Raghavendra Rao Ananta <rananta@codeaurora.org>
2020-08-21kernel_definitions: Pass TARGET_BUILD_VARIANT to generate_defconfig.shRaghavendra Rao Ananta
generate_defconfig.sh uses the TARGET_BUILD_VARIANT env variable to determine if DEBUG_FS has to be enabled or not. Hence, explicitly set this in generate_defconfig.sh's environment for it to take effect. Change-Id: I927b59971687d74dc41652888399df9ede547d8f Signed-off-by: Raghavendra Rao Ananta <rananta@codeaurora.org>
2020-08-10kernel_definitions: Force GKI kernel to be builtRaghavendra Rao Ananta
The build system doesn't seem to trigger the target to build the GKI kernel, thus leading to inconsistent builds. Hence, add a make target dependency on creating a GKI_OUT directory to force building GKI kernel. Change-Id: I58a3c3901de5bc6c67e02d9fc2cfb023b5b43e44 Signed-off-by: Raghavendra Rao Ananta <rananta@codeaurora.org>
2020-08-06kernel_definitions: Make GKI kernel dependent on UFDT_APPLY_OVERLAYRaghavendra Rao Ananta
With parallel GKI and QGKI kernel compilations, if GKI build starts first it needs the ufdt_apply_overlay host tool present. Hence, add an explicit dependency for the same. Change-Id: Ibc185d684b1ca3a1923c689e80904a3a5ee9a8cb Signed-off-by: Raghavendra Rao Ananta <rananta@codeaurora.org>
2020-07-29kernel_definitions: Build the QGKI and GKI kernels in parallelRaghavendra Rao Ananta
For $(PLATFORM)-qgki_defconfig, currently we build GKI and QGKI kernels in a serial manner. To improve the build time, build the kernels in parallel. For this, remove the 'make' target dependencies between the two kernel builds and make sure that the defconfigs for both the kernels are generated in sequence.

2020-06-23kernelscripts: Enhance the build scripts to build additional kernelRaghavendra Rao Ananta
For the sake of GKI compliance testing, QGKI and GKI should be sharing the same vendor.img and vendor_boot.img. Hence, the idea is to build the GKI kernel along with QGKI such that the modules could be packaged accordingly.

2020-04-28kernel_definitions: Avoid direct usage of TARGET_PRODUCTNaveen Ramaraj
This allows seeding of new Android lunch targets to be decoupled from kernel script updates. Remove this non portable usage and use TARGET_BOARD_PLATFORM instead which achieves the same result. Change-Id: I295be4aee000b4532854e15d844fa74423f52335
2020-04-20kernel_definitions: Export NMRaghavendra Rao Ananta
Export NM to llvm-nm prebuilts path as $NM is used internally by many of the kernel scripts. This is especially needed when LTO is enabled as GCC's nm utility fails to read the object files.

2020-02-11kernel/build: Add path for prebuilt location of makeJeevan Shriram
Android build system restricts usage of make from host machine and use the binaries from the prebuilt location. Update kernel script to use the make from prebuilt location. Change-Id: I3886e73a1a2219449a9fc4abb29ab7208a15eedf

Use AOSP LLVM for compiling the kernel. If the latest AOSP Clang is not present, fall back to the AOSP Clang specified in the platform toolchain. Change-Id: Iffac9dad320dc7f7de30480b2d3ca62bf8f05713 Signed-off-by: Prakruthi Deepak Heragu <pheragu@codeaurora.org>
2019-10-01kernelscripts: Add snapshots of buildkernel.sh and kernel_definitions.mkRaghavendra Rao Ananta
By default, the build.sh provides a mechanism to compile the kernel as a standalone component, and is not helpful to compile from within the Android tree. As a result, add the snapshots of kernel_definitions.mk and buildkernel.sh files to support kernel compilation from within the Android tree. The snaphot is taken from msm-4.19 branch as of commit <0780fd437f12d401c> (kernel/build: remove wildcard entry for updating makefile variable). Change-Id: I63b3859a9c7d7b5bcf19320fe62235f432f9817a
