[PATCH 28/31] tools, perf: Add a precise event qualifier

From: Andi Kleen Add a precise qualifier, like cpu/event=0x3c,precise=1/ This is needed so that the kernel can request enabling PEBS for TSX events. The parser bails out on any sysfs parse errors, so this is needed in any case to handle any event on the TSX perf kernel. Signed-off-by: Andi
