From f2ef6c6def237eb7dff413cac20ac80742141719 Mon Sep 17 00:00:00 2001 From: Alex Hong Date: Fri, 19 Jul 2019 16:37:33 +0800 Subject: [PATCH] ANDROID: Makefile: append BUILD_NUMBER to version string when defined In current implementation the Linux version string that is attached to the kernel linux image as well as the all kernel modules includes the sha1 of the main git project for the kernel. This Commit adds the BUILD_NUMBER env variable with an 'ab' prefix to the Linux version string. This maps to both the Linux Image and all kernel modules version strings. Bug: 159842160 Bug: 137521202 Test: Build the kernel and test the version string Change-Id: I4795955f36f477b257ca86495726e24d6b196d05 Signed-off-by: Alex Hong (cherry picked from commit e60f995403c9799dd0dc14d62d77d6698a8a7126) [willmcvicker: fix uts_len check to include -ab$(BUILD_NUMBER)] Signed-off-by: Will McVicker --- Makefile | 15 ++++++++++----- 1 file changed, 10 insertions(+), 5 deletions(-) diff --git a/Makefile b/Makefile index ab054406752f..0520bbd3b2db 100644 --- a/Makefile +++ b/Makefile @@ -1227,12 +1227,17 @@ endif # needs to be updated, so this check is forced on all builds uts_len := 64 +ifneq (,$(BUILD_NUMBER)) + UTS_RELEASE=$(KERNELRELEASE)-ab$(BUILD_NUMBER) +else + UTS_RELEASE=$(KERNELRELEASE) +endif define filechk_utsrelease.h - if [ `echo -n "$(KERNELRELEASE)" | wc -c ` -gt $(uts_len) ]; then \ - echo '"$(KERNELRELEASE)" exceeds $(uts_len) characters' >&2; \ - exit 1; \ - fi; \ - (echo \#define UTS_RELEASE \"$(KERNELRELEASE)\";) + if [ `echo -n "$(UTS_RELEASE)" | wc -c ` -gt $(uts_len) ]; then \ + echo '"$(UTS_RELEASE)" exceeds $(uts_len) characters' >&2; \ + exit 1; \ + fi; \ + (echo \#define UTS_RELEASE \"$(UTS_RELEASE)\";) endef define filechk_version.h
