2025-03-21	perf syscalltbl: Remove syscall_table.h	Ian Rogers	1	-8/+0
	The definition of "static const char *const syscalltbl[] = {" is done in a generated syscalls_32.h or syscalls_64.h that is architecture dependent. In order to include the appropriate file a syscall_table.h is found via the perf include path and it includes the syscalls_32.h or syscalls_64.h as appropriate. To support having multiple syscall tables, one for 32-bit and one for 64-bit, or for different architectures, an include path cannot be used. Remove syscall_table.h because of this and inline what it does into syscalltbl.c. For architectures without a syscall_table.h this will cause a failure to include either syscalls_32.h or syscalls_64.h rather than a failure to include syscall_table.h. For architectures that only included one or other, the behavior matches BITS_PER_LONG as previously done on architectures supporting both syscalls_32.h and syscalls_64.h.

2025-01-09	perf tools: Create generic syscall table support	Charlie Jenkins	1	-0/+8
	Currently each architecture in perf independently generates syscall headers. Adapt the work that has gone into unifying syscall header implementations in the kernel to work with perf tools. Introduce this framework with riscv at first. riscv previously relied on libaudit, but with this change, perf tools for riscv no longer needs this external dependency.
