    perf session: Use sensible mmap size · 55b44629
    Thomas Gleixner 提交于
    On 64bit we can map the whole file in one go, on 32bit we can at least map
    32MB and not map/unmap tiny chunks of the file.
    
    Base the progress bar on 1/16 of the data size.
    
    Preparatory patch to get rid of the malloc/memcpy/free of trace data.
