RISC-V test plan

[luhenry]

Relates to adoptium/temurin-build#3591

Action Items

• Rework gnu.testlet.java.lang.Math and gnu.testlet.java.lang.StrictMath in Mauve directly, the tests are broken for platform that have canonical NaNs

From a look over the results of https://ci.adoptium.net/job/Test_openjdk17_hs_extended.openjdk_riscv64_linux/10, I can identify at least two fixes that we need to do in OpenJDK, none are specific to RISC-V:

1. backport https://bugs.openjdk.org/browse/JDK-8286447 to fix all the java.lang.UnsatisfiedLinkError: Can't load library: /path/to/lib/runtime/lib/libawt_xawt.so. This error is the root cause for all failures in tools/jpackage
2. use a proper IP for java/net/Socket/B8312065.java which may not be used on the local network, see https://www.rfc-editor.org/rfc/rfc5737 for the right way of doing it.
3. increase the timeout for jdk/incubator/vector/VectorMaxConversionTests.java#id1, the test doesn't deadlock as it's still running. The cause of the timeout is simply no hardware acceleration (the hardware doesn't support it) with slow hardware.

I still have to identify the cause of the crash for sun/tools/jhsdb/HeapDumpTest.java.

• Should be fixed by 8286447: [Linux] AWT should start in Headless mode if headful AWT library not installed openjdk/jdk17u-dev#2150

2. use a proper IP for java/net/Socket/B8312065.java which may not be used on the local network, see https://www.rfc-editor.org/rfc/rfc5737 for the right way of doing it.

• Should be fixed by 8324234: Use reserved IP for java.net testing openjdk/jdk17u-dev#2149

3. increase the timeout for jdk/incubator/vector/VectorMaxConversionTests.java#id1, the test doesn't deadlock as it's still running. The cause of the timeout is simply no hardware acceleration (the hardware doesn't support it) with slow hardware.

• Should be fixed by RISC-V: Increase timeout for OpenJDK tests #4990

I still have to identify the cause of the crash for sun/tools/jhsdb/HeapDumpTest.java

From early debugging, it's most likely related to the message WARNING: getThreadIntegerRegisterSet0: get_lwp_regs failed for lwp in jmap's stderr in the test

• Should be fixed by 8307955: Prefer to PTRACE_GETREGSET instead of PTRACE_GETREGS in method 'ps_proc.c::process_get_lwp_regs' openjdk/jdk17u-dev#2152
