2025-10-02perf map: Constify objdump offset/address conversion APIsIan Rogers2-7/+18

2025-10-02perf tools kvm: Use "cycles" to sample guest for "kvm record" on IntelDapeng Mi3-10/+61
After KVM supports PEBS for guest on Intel platforms (https://lore.kernel.org/all/20220411101946.20262-1-likexu@tencent.com/), host loses the capability to sample guest with PEBS since all PEBS related MSRs are switched to guest value after vm-entry, like IA32_DS_AREA MSR is switched to guest GVA at vm-entry. This would lead to "perf kvm record" fails to sample guest on Intel platforms since "cycles:P" event is used to sample guest by default as below case shows. sudo perf kvm record -a ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.787 MB perf.data.guest ] So to ensure guest record can be sampled successfully, use "cycles" instead of "cycles:P" to sample guest record by default on Intel platforms.

A key feature for the new bitmap are that the IO fastpath is lockless. If a user issues lots of write IO to the same bitmap bit in a short time, only the first write has additional overhead to update bitmap bit, no additional overhead for the following writes. By supporting only resync or recover written data, means in the case creating new array or replacing with a new disk, there is no need to do a full disk resync/recovery. - Switch ->getgeo() and ->bios_param() to using struct gendisk rather than struct block_device. - Rust block changes via Andreas. This series adds configuration via configfs and remote completion to the rnull driver. The series also includes a set of changes to the rust block device driver API: a few cleanup patches, and a few features supporting the rnull changes. The series removes the raw buffer formatting logic from `kernel::block` and improves the logic available in `kernel::string` to support the same use as the removed logic. - floppy arch cleanups - Reduce the number of dereferencing needed for ublk commands - Restrict supported sockets for nbd.

perf doesn't use libtracefs and so it doesn't make sense to assume it is always available when building test-all.bin, defeating the feature check speedup it provides. The other tools/build/ users such as rtla, rv, etc call $(feature_check libtracefs) to check its availability instead of using the test-all.bin mechanism, stopping the build and asking for libtracefs-devel to be installed. Remove it from FEATURE_TESTS_BASIC to not have it as available, as noted by Ian Rogers during review.

So get rid of it by implementing custom variants of those macros that will work both in kernel and Github mirror repos.
