[PATCH v3 0/5] KVM: selftests: aarch64: Introduce pmu_event_filter_test

by Shaoqin Huang

The test is inspired by the pmu_event_filter_test which implemented by x86. On the arm64 platform, there is the same ability to set the pmu_event_filter through the KVM_ARM_VCPU_PMU_V3_FILTER attribute. So add the test for arm64. The series first move some pmu common code from vpmu_counter_access to lib/aarch64/vpmu.c and include/aarch64/vpmu.h, which can be used by pmu_event_filter_test. Then fix a bug related to the [enable|disable]_counter, and at last, implement the test itself. Changelog: ---------- v2->v3: - Check the pmceid in guest code instead of pmu event count since different hardware may have different event count result, check pmceid makes it stable on different platform. [Eric] - Some typo fixed and commit message improved. v1->v2: - Improve the commit message. [Eric] - Fix the bug in [enable|disable]_counter. [Raghavendra & Marc] - Add the check if kvm has attr KVM_ARM_VCPU_PMU_V3_FILTER. - Add if host pmu support the test event throught pmceid0. - Split the test_invalid_filter() to another patch.

[PATCH net-next] selftests: net: Add missing matchall classifier

by Ido Schimmel

One of the test cases in the test_bridge_backup_port.sh selftest relies on a matchall classifier to drop unrelated traffic so that the Tx drop counter on the VXLAN device will only be incremented as a result of traffic generated by the test. However, the configuration option for the matchall classifier is missing from the configuration file which might explain the failures we see in the netdev CI [1]. Fix by adding CONFIG_NET_CLS_MATCHALL to the configuration file. [1] # Backup nexthop ID - invalid IDs # ------------------------------- [...] # TEST: Forwarding out of vx0 [ OK ] # TEST: No forwarding using backup nexthop ID [ OK ] # TEST: Tx drop increased [FAIL] # TEST: IPv6 address family nexthop as backup nexthop [ OK ] # TEST: No forwarding out of swp1 [ OK ] # TEST: Forwarding out of vx0 [ OK ] # TEST: No forwarding using backup nexthop ID [ OK ] # TEST: Tx drop increased [FAIL] [...] Fixes: b408453053fb ("selftests: net: Add bridge backup port and backup nexthop ID test") Signed-off-by: Ido Schimmel <idosch(a)nvidia.com> --- Jakub, you can apply to net if you want to, but I'm sending this to net-next since I want to see if it helps the CI.

[PATCH 0/3] riscv: mm: Use hint address in mmap if available

by Charlie Jenkins

On riscv, mmap currently returns an address from the largest address space that can fit entirely inside of the hint address. This makes it such that the hint address is almost never returned. This patch raises the mappable area up to and including the hint address. This allows mmap to often return the hint address, which allows a performance improvement over searching for a valid address as well as making the behavior more similar to other architectures.
