When the Intel Sub-NUMA Clustering(SNC) feature is enabled,
the CMT and MBM counters may not be accurate.
In this case, skip MBM&CMT tests.

Hello,
According to the Intel RDT reference Manual,
when the sub-numa clustering feature is enabled, the CMT and MBM counters may not be accurate.
When running CMT tests and MBM tests on Intel processor, the result is "not ok".
So, fix it to skip the CMT & MBM test When the Intel Sub-NUMA Clustering(SNC) feature is enabled.
Thanks,

FWIW this patch did not make it to patchwork or any of the mailing
lists. Not immediately obvious why. Can you try re-sending?
Mark the summary result as FAIL to prevent from confusing the selftest
framework if some of them are failed.
Previously, the selftest framework always treats it as *ok* even though
some of them are failed actually. That's because the script tdc.sh always
return 0.

2.32.0
Synchronous Ethernet networks use a physical layer clock to syntonize
the frequency across different network elements.
Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet
Equipment Clock (EEC) and have the ability to recover synchronization
from the synchronization inputs - either traffic interfaces or external
frequency sources.
The EEC can synchronize its frequency (syntonize) to any of those sources.
It is also able to select synchronization source through priority tables
and synchronization status messaging. It also provides neccessary
filtering and holdover capabilities
This patch series introduces basic interface for reading the Ethernet
Equipment Clock (EEC) state on a SyncE capable device. This state gives
information about the source of the syntonization signal (ether my port,
or any external one) and the state of EEC. This interface is required\
to implement Synchronization Status Messaging on upper layers.
v3:
- remove RTM_GETRCLKRANGE
- return state of all possible pins in the RTM_GETRCLKSTATE
- clarify documentation
v2:
- improved documentation
- fixed kdoc warning
RFC history:
v2:
- removed whitespace changes
- fix issues reported by test robot
v3:
- Changed naming from SyncE to EEC
- Clarify cover letter and commit message for patch 1
v4:
- Removed sync_source and pin_idx info
- Changed one structure to attributes
- Added EEC_SRC_PORT flag to indicate that the EEC is synchronized
to the recovered clock of a port that returns the state

- implement support for recovered clocks
- align states returned by EEC to ITU-T G.781
v6:
- fix EEC clock state reporting
- add documentation
- fix descriptions in code comments

Commit be79505caf3f ("tools/runqslower: Install libbpf headers when
building") uses the target libbpf to build the host bpftool, which
doesn't work when cross-building:
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -C tools/bpf/runqslower O=/tmp/runqslower
...
LINK /tmp/runqslower/bpftool/bpftool
/usr/bin/ld: /tmp/runqslower/libbpf/libbpf.a(libbpf-in.o): Relocations in generic ELF (EM: 183)
/usr/bin/ld: /tmp/runqslower/libbpf/libbpf.a: error adding symbols: file in wrong format
collect2: error: ld returned 1 exit status
When cross-building, the target architecture differs from the host. The
bpftool used for building runqslower is executed on the host, and thus
must use a different libbpf than that used for runqslower itself.
Remove the LIBBPF_OUTPUT and LIBBPF_DESTDIR parameters, so the bpftool
build makes its own library if necessary.
In the selftests, pass the host bpftool, already a prerequisite for the
runqslower recipe, as BPFTOOL_OUTPUT. The runqslower Makefile will use
the bpftool that's already built for selftests instead of making a new
one.

Odpowiednio dobrana instalacja fotowoltaiczna to rozwiązanie, które pozwala wygenerować spore oszczędności w skali roku.
Chciałbym porozmawiać z Państwem o tego typu rozwiązaniu, a także przedstawić wstępne kalkulacje.
Czy są Państwo zainteresowani?

2.26.3
V2 available at:
https://lore.kernel.org/lkml/cover.1635447301.git.reinette.chatre@intel.com/
Changes since V2:
- Remove the non-kselftest placeholder patches while also removing their
usage within the SGX selftests. Instead, the SGX selftests obtain needed
data from CPUID directly (Dave).
- Rewrite commit message of "selftests/x86/sgx: Fix a benign linker
warning" (Dave).
- Add Jarkko's signature to "selftests/sgx: Add page permission and
exception test" (Jarkko).
V1 available at:
https://lore.kernel.org/lkml/cover.1631731214.git.reinette.chatre@intel.com/
Changes since V1:
- Biggest change: The non-kselftest placeholder patches included in this series
that the kselftest work depends on are still being discussed elsewhere
(link below) but has changed significantly since the first submission,
warranting an update to the kselftest patches that depend on it.
Jarkko: I made significant modifications to your
"selftests/sgx: Add a new kselftest: unclobbered_vdso_oversubscribed"
that you may want to look at.
- Improve cover letter and changelogs (Dave).
- Add Jarkko and Dave's signatures where obtained (Jarkko and Dave).
- Fix Cedric's signature in patch 1 (Jarkko and Cedric).
- Improve the loop locating the data segment (Jarkko).
- Update placeholder patches that makes the amount of SGX memory available to
latest version (v8). Previously this dependency consisted out of one
patch, now it spans two.
Hi Everybody,
This series consists out of outstanding SGX selftests changes, rebased
and gathered in a single series that can easily be merged for testing
and development, and a few more changes added to expand the existing tests.
The outstanding SGX selftest changes included in this series that have already
been submitted separately are:
* A more than two year old patch fixing a benign linker warning that is still
present today:
https://lore.kernel.org/linux-sgx/20191017030340.18301-2-sean.j.christopher…
The original patch is added intact and not all email addresses
within are valid.
* Latest (v4) of Jarkko Sakkinen's series to add an oversubscription test:
https://lore.kernel.org/linux-sgx/20210809093127.76264-1-jarkko@kernel.org/
* Latest (v2) of Jarkko Sakkinen's patch that provides per-op
parameter structs for the test enclave:
https://lore.kernel.org/linux-sgx/20210812224645.90280-1-jarkko@kernel.org/
The new changes introduced in this series builds on Jarkko's outstanding
SGX selftest changes and adds new tests for page permissions, exception
handling, and thread entry.
Building and running enclaves is painful and traditionally requires a
big software stack. This adds features like threads to the SGX selftests
which are traditionally implemented in that big software stack. This
helps test SGX kernel support with only code from the kernel tree.
Reinette
Jarkko Sakkinen (8):
selftests/sgx: Assign source for each segment
selftests/sgx: Make data measurement for an enclave segment optional
selftests/sgx: Create a heap for the test enclave
selftests/sgx: Dump segments and /proc/self/maps only on failure
selftests/sgx: Encpsulate the test enclave creation
selftests/sgx: Move setup_test_encl() to each TEST_F()

2.25.1
This is a series of fixes for minor problems in the building of the GPIO
selftests introduced by my rework of those tests.
The first patch is from Li Zhijian and fixes a compiler error when
building the selftests in environments with stale system includes.
I have reworded the commit comment to make it more to the point in
describing the root cause of the problem and the fix, as suggested by
Shuah in his initial review of that patch.
The second patch fixes a warning when the tests are compiled with -Wall,
and the final patch restores the CFLAGS that should not have been removed
in the rework, including the -Wall.
