[PATCH v1 0/6] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards.

[PATCH v2 0/3] kselftest/arm64: fp-stress performance improvements

by Mark Brown

This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal. v2: - Rebase onto arm64/for-next/selftests Mark Brown (3): kselftest/arm64: Hold fp-stress children until they're all spawned kselftest/arm64: Don't drain output while spawning children kselftest/arm64: Allow epoll_wait() to return more than one result tools/testing/selftests/arm64/fp/fp-stress.c | 74 +++++++++++++++----- 1 file changed, 57 insertions(+), 17 deletions(-) base-commit: 642978981ec8a79da00828c696c58b3732b993a6 -- 2.30.2

[PATCH net-next 00/11] mptcp: PM listener events + selftests cleanup

by Matthieu Baerts

Thanks to the patch 6/11, the MPTCP path manager now sends Netlink events when MPTCP listening sockets are created and closed. The reason why it is needed is explained in the linked ticket [1]: MPTCP for Linux, when not using the in-kernel PM, depends on the userspace PM to create extra listening sockets before announcing addresses and ports. Let's call these "PM listeners". With the existing MPTCP netlink events, a userspace PM can create PM listeners at startup time, or in response to an incoming connection. Creating sockets in response to connections is not optimal: ADD_ADDRs can't be sent until the sockets are created and listen()ed, and if all connections are closed then it may not be clear to the userspace PM daemon that PM listener sockets should be cleaned up. Hence this feature request: to add MPTCP netlink events for listening socket close & create, so PM listening sockets can be managed based on application activity. [1] https://github.com/multipath-tcp/mptcp_net-next/issues/313 Selftests for these new Netlink events have been added in patches 9,11/11. The remaining patches introduce different cleanups and small improvements in MPTCP selftests to ease the maintenance and the addition of new tests.

[PATCH v3 0/9] KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg

by Janis Schoetterl-Glausch

User space can use the MEM_OP ioctl to make storage key checked reads and writes to the guest, however, it has no way of performing atomic, key checked, accesses to the guest. Extend the MEM_OP ioctl in order to allow for this, by adding a cmpxchg mode. For now, support this mode for absolute accesses only. This mode can be use, for example, to set the device-state-change indicator and the adapter-local-summary indicator atomically. Also contains some fixes/changes for the memop selftest independent of the cmpxchg changes. v2 -> v3 * rebase onto the wip/cmpxchg_user_key branch in the s390 kernel repo * use __uint128_t instead of unsigned __int128 * put moving of testlist into main into separate patch * pick up R-b's (thanks Nico) v1 -> v2 * get rid of xrk instruction for cmpxchg byte and short implementation * pass old parameter via pointer instead of in mem_op struct * indicate failure of cmpxchg due to wrong old value by special return code * picked up R-b's (thanks Thomas) Janis Schoetterl-Glausch (9): KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg Documentation: KVM: s390: Describe KVM_S390_MEMOP_F_CMPXCHG KVM: s390: selftest: memop: Pass mop_desc via pointer KVM: s390: selftest: memop: Replace macros by functions KVM: s390: selftest: memop: Move testlist into main KVM: s390: selftest: memop: Add cmpxchg tests KVM: s390: selftest: memop: Add bad address test KVM: s390: selftest: memop: Fix typo KVM: s390: selftest: memop: Fix wrong address being used in test Documentation/virt/kvm/api.rst | 21 +- include/uapi/linux/kvm.h | 5 + arch/s390/kvm/gaccess.h | 3 + arch/s390/kvm/gaccess.c | 101 ++++ arch/s390/kvm/kvm-s390.c | 35 +- tools/testing/selftests/kvm/s390x/memop.c | 670 +++++++++++++++++----- 6 files changed, 683 insertions(+), 152 deletions(-) Range-diff against v2: 1: c6731b0063ab ! 1: 94820a73e9b0 KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg @@ arch/s390/kvm/gaccess.h: int access_guest_with_key(struct kvm_vcpu *vcpu, unsign void *data, unsigned long len, enum gacc_mode mode);

[PATCH v3 0/7] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration, support for providing user visible descriptions and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v3: - "Rebase" onto Takashi's current tree (with a revert). - Include Jaroslav's changes to specify all tests in the configuration file parsing. - Add a new "description" field to the configuration instead of trying to name the tests. - Always run both default and per-system tests, logging our success at setting the per-system configurations as a separate test since they shouldn't fail. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing.

[PATCH] kselftests/alsa: pcm - move more configuration to configuration files

by Jaroslav Kysela

Obtain all test parameters from the configuration files. The defaults are defined in the pcm-test.conf file. The test count and parameters may be variable per specific hardware. Also, handle alt_formats field now (with the fixes in the format loop). It replaces the original "automatic" logic which is not so universal. The code may be further extended to skip various tests based on the configuration hints, if the exact PCM hardware parameters are not available for the given hardware.
