2022-03-01perf: Add irq and exception return branch typesAnshuman Khandual2-1/+5
This expands generic branch type classification by adding two more entries there in i.e irq and exception return. Also updates the x86 implementation to process X86_BR_IRET and X86_BR_IRQ records as appropriate. This changes branch types reported to user space on x86 platform but it should not be a problem. The possible scenarios and impacts are enumerated here. Signed-off-by: Peter Zijlstra (Intel) <[email protected]> Link: https://lkml.kernel.org/r/[email protected]
2022-03-01KVM: selftests: Add test to verify KVM handling of ICRSean Christopherson4-0/+153
The main thing that the selftest verifies is that KVM copies x2APIC's ICR[63:32] to/from ICR2 when userspace accesses the vAPIC page via KVM_{G,S}ET_LAPIC. KVM previously split x2APIC ICR to ICR+ICR2 at the time of write (from the guest), and so KVM must preserve that behavior for backwards compatibility between different versions of KVM. It will also test other invariants, e.g. that KVM clears the BUSY flag on ICR writes, that the reserved bits in ICR2 are dropped on writes from the guest, etc...

2022-03-01libbpf: Skip forward declaration when counting duplicated type namesXu Kuohai1-0/+5
Currently if a declaration appears in the BTF before the definition, the definition is dumped as a conflicting name, e.g.: $ bpftool btf dump file vmlinux format raw | grep "'unix_sock'" [81287] FWD 'unix_sock' fwd_kind=struct [89336] STRUCT 'unix_sock' size=1024 vlen=14 $ bpftool btf dump file vmlinux format c | grep "struct unix_sock" struct unix_sock; struct unix_sock___2 { <--- conflict, the "___2" is unexpected struct unix_sock___2 *unix_sk; This causes a compilation error if the dump output is used as a header file.

When a BPF map of type BPF_MAP_TYPE_PERF_EVENT_ARRAY doesn't have the max_entries parameter set, the map will be created with max_entries set to the number of available CPUs. When we try to reuse such a pinned map, map_is_reuse_compat will return false, as max_entries in the map definition differs from max_entries of the existing map, causing the following error: libbpf: couldn't reuse pinned map at '/sys/fs/bpf/m_logging': parameter mismatch Fix this by overwriting max_entries in the map definition. For this to work, we need to do this in bpf_object__create_maps, before calling bpf_object__reuse_map.

2022-02-28bpftool: Remove redundant slashesYuntao Wang1-7/+7
Because the OUTPUT variable ends with a slash but CURDIR doesn't, to keep the _OUTPUT value consistent, we add a trailing slash to CURDIR when defining _OUTPUT variable. Since the _OUTPUT variable holds a value ending with a trailing slash, there is no need to add another one when defining BOOTSTRAP_OUTPUT and LIBBPF_OUTPUT variables. Likewise, when defining LIBBPF_INCLUDE and LIBBPF_BOOTSTRAP_INCLUDE, we shouldn't add an extra slash either for the same reason. When building libbpf, the value of the DESTDIR argument should also not end with a trailing slash.

2022-02-25rtla/hist: Make -E the short version of --entriesDaniel Bristot de Oliveira2-10/+10
Currently, --entries uses -e as the short version in the hist mode of timerlat and osnoise tools. But as -e is already used to enable events on trace sessions by other tools, thus let's keep it available for the same usage for all rtla tools. Make -E the short version of --entries for hist mode on all tools. Note: rtla was merged in this merge window, so rtla was not released yet.

2022-02-25selftests/rtc: continuously read RTC in a loop for 30sMateusz Jończyk2-1/+67
Some problems with reading the RTC time may happen rarely, for example while the RTC is updating. So read the RTC many times to catch these problems. For example, a previous attempt for my commit ea6fa4961aab ("rtc: mc146818-lib: fix RTC presence check") was incorrect and would have triggered this selftest. To avoid the risk of damaging the hardware, wait 11ms before consecutive reads. In rtc_time_to_timestamp I copied values manually instead of casting - just to be on the safe side. The 11ms wait period was chosen so that it is not a divisor of 1000ms.

Some features may invalidate some tests, for example by supporting an operation which would trap otherwise. Allow tests to list features that they are incompatible with so we can cover the case where a signal will be generated without disruption on systems where that won't happen.

For now, support a single flag, KVM_PMU_CAP_DISABLE, to allow disabling PMU virtualization for a VM even when KVM is configured with enable_pmu=true a module level. To keep KVM simple, disallow changing VM's PMU configuration after vCPUs have been created.

2022-02-25KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3Mark Brown3-2/+13
The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.
