tools headers: Restore READ_ONCE() C++ compatibility

2018-04-12T12:30:09Z

Our userspace defines READ_ONCE() in a way that clang doesn't like, as we have an anonymous union in which neither field is initialized. WRITE_ONCE() is fine since it initializes the __val field. For READ_ONCE() we can keep clang and GCC happy with a dummy initialization of the __c field, so let's do that. At the same time, let's split READ_ONCE() and WRITE_ONCE() over several lines for legibility, as we do in the in-kernel .

xarray: add the xa_lock to the radix_tree_root

2018-04-11T17:28:39Z

This results in no change in structure size on 64-bit machines as it fits in the padding between the gfp_t and the void *. 32-bit machines will grow the structure from 8 to 12 bytes. Almost all radix trees are protected with (at least) a spinlock, so as they are converted from radix trees to xarrays, the data structures will shrink again. Initialising the spinlock requires a name for the benefit of lockdep, so RADIX_TREE_INIT() now needs to know the name of the radix tree it's initialising, and so do IDR_INIT() and IDA_INIT(). Also add the xa_lock() and xa_unlock() family of wrappers to make it easier to use the lock. If we could rely on -fplan9-extensions in the compiler, we could avoid all of this syntactic sugar, but that wasn't added until gcc 4.6.

perf tools: Add MEM_TOPOLOGY feature to perf data file

2018-03-08T14:30:46Z

Adding MEM_TOPOLOGY feature to perf data file, that will carry physical memory map and its node assignments. The format of data in MEM_TOPOLOGY is as follows: 0 - version | for future changes 8 - block_size_bytes | /sys/devices/system/memory/block_size_bytes 16 - count | number of nodes For each node we store map of physical indexes for each node: 32 - node id | node index 40 - size | size of bitmap 48 - bitmap | bitmap of memory indexes that belongs to node | /sys/devices/system/node/node/memory The MEM_TOPOLOGY could be displayed with following report command: $ perf report --header-only -I ... # memory nodes (nr 1, block size 0x8000000): # 0 [7G]: 0-23,32-69 Signed-off-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Cc: Alexander Shishkin Cc: David Ahern Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20180307155020.32613-8-jolsa@kernel.org [ Rename 'index' to 'idx', as this breaks the build in rhel5, 6 and other systems where this is used by glibc headers ] Signed-off-by: Arnaldo Carvalho de Melo
