perf/x86/intel: Fix invalid Bit 13 for Icelake MSR_OFFCORE_RSP_x register
The Intel SDM states that bit 13 of Icelake's MSR_OFFCORE_RSP_x register is valid, and used for counting hardware generated prefetches of L3 cache. Update the bitmask to allow bit 13. Before: $ perf stat -e cpu/event=0xb7,umask=0x1,config1=0x1bfff/u sleep 3 Performance counter stats for 'sleep 3': <not supported> cpu/event=0xb7,umask=0x1,config1=0x1bfff/u After: $ perf stat -e cpu/event=0xb7,umask=0x1,config1=0x1bfff/u sleep 3 Performance counter stats for 'sleep 3': 9,293 cpu/event=0xb7,umask=0x1,config1=0x1bfff/u Signed-off-by: Yunying Sun <yunying.sun@intel.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Kan Liang <kan.liang@linux.intel.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: acme@kernel.org Cc: alexander.shishkin@linux.intel.com Cc: bp@alien8.de Cc: hpa@zytor.com Cc: jolsa@redhat.com Cc: namhyung@kernel.org Link: https://lkml.kernel.org/r/20190724082932.12833-1-yunying.sun@intel.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
