[Valgrind-developers] New risc-v builder.sourceware.org CI workers (p550 and bpi-f3)

[Mark W. <ma...@kl...>]

Hi,

Thanks to RISC-V International we got 3 new buildbot CI workers.  One
HiFive Premier P550 https://www.sifive.com/boards/hifive-premier-p550
and two Banana Pi BPI-F3 https://wiki.banana-pi.org/Banana_Pi_BPI-F3

They have been used for testing the proposed Valgrind risc-vv backend:
https://bugs.kde.org/show_bug.cgi?id=468575
Test results look good, but we can use some help integrating and
maintaining it.

The P550 now runs a gdb and full testsuite build:
https://builder.sourceware.org/buildbot/#/builders/gdb-riscv-full

Results look fairly good:

	     === gdb Summary ===

# of unexpected core files   1
# of expected passes 	     121159
# of unexpected failures     333
# of expected failures       88
# of known failures          116
# of untested testcases      41
# of unresolved testcases    20
# of unsupported tests       827
# of paths in test names     2
# of duplicate test names    8

There are also gdb full test builds for amd64 and arm64
https://builder.sourceware.org/buildbot/#/builders?tags=gdb-full
All results are in bunsen to make it easy to compare
https://builder.sourceware.org/testruns/?has_keyvalue_op=glob&has_keyvalue_k=testrun.git_describe&has_keyvalue_v=buildbot/gdb-%2A-full%2A

One bpi-f3 runs glibc and the full testsuite.
https://builder.sourceware.org/buildbot/#/builders/glibc-fedora-riscv
There is one failure rt/tst-clock_nanosleep2 which seems a testsuite
issue which is being discussed. And one flaky test
stdio-common/tst-fwrite-bz29459 which also occassionally fails on
other arches.

The other bpi-f3 runs a gcc bootstrap and full testsuite.
https://builder.sourceware.org/buildbot/#/builders/gcc-full-spacemit-x60
This takes ~22+ hours (7:30 hours bootstrap, 14:30 hours tests)
This is a lot slower than the pioneer box (which has 64 cores)
https://builder.sourceware.org/buildbot/#/builders/gcc-full-fedora-riscv
but the bpi-f3 has an 8 core SpacemiT K1 supporting rvv 1.0.

Test results attached.

Cheers,

Mark
