[ Upstream commit 815c1560bf8fd522b8d93a1d727868b910c1cc24 ] With Java 11 there is no seperate JRE anymore. Details: https://coderanch.com/t/701603/java/JRE-JDK Therefore the detection of the JRE needs to be adapted. This change works for s390 and x86. I have not tested other platforms. Committer testing: Continues to work with the OpenJDK 8: $ rm -f ~acme/lib64/libperf-jvmti.so $ rpm -qa | grep jdk-devel java-1.8.0-openjdk-devel-1.8.0.222.b10-0.fc30.x86_64 $ git log --oneline -1 a51937170f33 (HEAD -> perf/core) perf build: Add detection of java-11-openjdk-devel package $ rm -rf /tmp/build/perf ; mkdir -p /tmp/build/perf ; make -C tools/perf O=/tmp/build/perf install > /dev/null 2>1 $ ls -la ~acme/lib64/libperf-jvmti.so -rwxr-xr-x. 1 acme acme 230744 Sep 24 16:46 /home/acme/lib64/libperf-jvmti.so $ Suggested-by: Andreas Krebbel <krebbel@linux.ibm.com> Signed-off-by: Thomas Richter <tmricht@linux.ibm.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Hendrik Brueckner <brueckner@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: http://lore.kernel.org/lkml/20190909114116.50469-4-tmricht@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
