tools headers uapi: Sync asm-generic/mman-common.h and linux/mman.h

2019-03-28T17:31:56Z

To deal with the move of some defines from asm-generic/mmap-common.h to linux/mman.h done in: 746c9398f5ac ("arch: move common mmap flags to linux/mman.h") The generated mmap_flags array stays the same: $ tools/perf/trace/beauty/mmap_flags.sh static const char *mmap_flags[] = { [ilog2(0x40) + 1] = "32BIT", [ilog2(0x01) + 1] = "SHARED", [ilog2(0x02) + 1] = "PRIVATE", [ilog2(0x10) + 1] = "FIXED", [ilog2(0x20) + 1] = "ANONYMOUS", [ilog2(0x100000) + 1] = "FIXED_NOREPLACE", [ilog2(0x0100) + 1] = "GROWSDOWN", [ilog2(0x0800) + 1] = "DENYWRITE", [ilog2(0x1000) + 1] = "EXECUTABLE", [ilog2(0x2000) + 1] = "LOCKED", [ilog2(0x4000) + 1] = "NORESERVE", [ilog2(0x8000) + 1] = "POPULATE", [ilog2(0x10000) + 1] = "NONBLOCK", [ilog2(0x20000) + 1] = "STACK", [ilog2(0x40000) + 1] = "HUGETLB", [ilog2(0x80000) + 1] = "SYNC", }; $ And to have the system's sys/mman.h find the definition of MAP_SHARED and MAP_PRIVATE, make sure they are defined in the tools/ mman-common.h in a way that keeps it the same as the kernel's, need for keeping the Android's NDK cross build working.

perf beauty msg_flags: Add missing %s lost when adding prefix suppression logic

Rename build libperf to perf, because it's used to build perf. The libperf build object name will be used for libperf library.

perf beauty waitid options: Fix up prefix showing logic

2019-02-14T16:31:12Z

When introducing the possibility for selecting if the common prefix to options such as the waitid ones, i.e. all 'waitid' options start with 'W', so, to make it make it more compact if configured to suppress it, 'perf trace' will do so, other examples include mmap's PROT_ prefix for its 'prot' argument, etc, which, when showing the syscall argument name ends up producing duplicated info that clutters the screen, i.e.: # perf trace -e mmap --max-events 2 sleep 1 0.000 ( 0.014 ms): sleep/20886 mmap(len: 112595, prot: PROT_READ, flags: MAP_PRIVATE, fd: 3) = 0x7f3e986d2000 0.041 ( 0.005 ms): sleep/20886 mmap(len: 8192, prot: PROT_READ|PROT_WRITE, flags: MAP_PRIVATE|MAP_ANONYMOUS) = 0x7f3e986d0000 # So it is possible to suppress that and make it more compact by having this in your ~/.perfconfig: # cat ~/.perfconfig [trace] show_prefix = no # # perf trace -e mmap --max-events 2 sleep 1 0.000 ( 0.014 ms): sleep/8009 mmap(len: 112595, prot: READ, flags: PRIVATE, fd: 3) = 0x7ff2373de000 0.040 ( 0.005 ms): sleep/8009 mmap(len: 8192, prot: READ|WRITE, flags: PRIVATE|ANONYMOUS) = 0x7ff2373dc000 # To have it look more like strace's output, we instead want to suppress the arg name and show the prefix, so use: # cat ~/.perfconfig [trace] show_prefix = yes show_arg_names = no # # perf trace -e mmap --max-events 2 sleep 1 0.000 ( 0.006 ms): sleep/15513 mmap(NULL, 112595, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7f7a9b6d3000 0.020 ( 0.002 ms): sleep/15513 mmap(NULL, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS) = 0x7f7a9b6d1000 # When this logic was introduced a bug came with it when processing the waitid 'option' arg that ended up expecting 3 strings when just two were being provided, fix it.

It is possible to pass a negative number as the fd and that has to be handled, so stop using 'unsigned int fd' in the ioctl syscall 'cmd' beautifier.
