2020-12-24perf s390: Move syscall.tbl check into check-headers.shTiezhu Yang1-4/+0
It is better to check syscall.tbl for s390 in check-headers.sh, it is similar with commit c9b51a017065 ("perf tools: Move syscall_64.tbl check into check-headers.sh").

2018-02-15perf s390: Rework system call table creation by using syscall.tblHendrik Brueckner1-3/+7
Recently, s390 uses a syscall.tbl input file to generate its system call table and unistd uapi header files. Hence, update mksyscalltbl to use it as input to create the system table for perf.

This should speed up accessing new system calls introduced with the kernel rather than waiting for libaudit updates to include them.

2017-12-05perf s390: add regs_query_register_offset()Hendrik Brueckner1-0/+1
The regs_query_register_offset() helper function converts register name like "%r0" to an offset of a register in user_pt_regs It is required by the BPF prologue generator. The user_pt_regs structure was recently added to "asm/ptrace.h". Hence, update tools/perf/check-headers.sh to keep the header file in sync with kernel changes.

2014-07-16perf kvm: Add stat support on s390Alexander Yarygin1-0/+2
On s390, the vmexit event has a tree-like structure: between exit_event_begin and exit_event_end several other events may happen and with each of them refining the previous ones. This patch adds a decoder for such events to the generic code and also the files <asm/kvm_perf.h> and kvm-stat.c for s390. Commands 'perf kvm stat record', 'report' and 'live' are supported.
