For some analysis, only a subset of the registers is useful. Changes: - Make --intr-regs accept register names to limit volume of data collected - Make perf script print interrupted machine register values with -F iregs - Make perf script print branch stack content with -F brstack $ perf record --intr-regs=\? available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10 R11 R12 R13 R14 R15 ... $ perf record --intr-regs=ax,bx,cx,dx,si .... $ perf script -F ip,iregs 40afc2 AX:0x6c5770 BX:0x1e CX:0x5f4d80a DX:0x101010101010101 SI:0x1 $ perf script -F ip,brstack ....
