Solution of Version Conflict between linux Compilation kernel and svn

Phenomenon

The system could have compiled the linux system kernel normally, but after installing svn, kernel compiled incorrectly.

Cause analysis

Navigating to drivers/gpu/mali/ump/Makefile. common and drivers/gpu/mali/mali/Makefile both have statements about SVN_REV: = xxxx. Normally, SVN_REV: = is empty. When the svn version is checked, SVN_REV: = has a value, causing the judgment in the script to go to the wrong branch.

Solution

Assign the SVN_REV values in both files to null "".

drivers/gpu/mali/ump/Makefile. common:

 16 # Get subversion revision number, fall back to 0000 if no svn info is available
 17 #SVN_REV:=$(shell ((svnversion | grep -qv exported && echo -n 'Revision: ' && svnversion) || git svn info | sed -e 's/$$$$/M/' | grep     '^Revision: ' || echo ${MALI_RELEASE_NAME}) 2>/dev/null | sed -e 's/^Revision: //')
 19 SVN_REV:=""

drivers/gpu/mali/mali/Makefile:

117 #SVN_REV := $(shell (cd $(DRIVER_DIR); (svnversion | grep -qv exported && svnversion) || git svn info | grep '^Revision: '| sed -e 's/    ^Revision: //' ) 2>/dev/null )
119 SVN_REV := ""
