From f82b77462b8680b84e8cce955b05a6629cb44b36 Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Wed, 14 Sep 2016 10:57:29 +0000 Subject: tools include: Add mman macros needed by perf for all arch Some macros required by tools/perf/trace/beauty/mmap.c is not support for all architectures. For example, MAP_32BIT is defined on x86 only, alpha doesn't define MADV_HWPOISON and MADV_SOFT_OFFLINE. This patch regenerates mman.h for each arch, defines these missing macros for perf. For missing MADV_*, fall back to asm-generic/mman-common because they are in a 'case ...' statement. For flags, define it to 0. Following is the script to generate this patch: macros=`cat $0 | awk 'V==1 {print}; /^# start macro list/ {V=1}'` rm `find ./tools/arch/ -name mman.h` for arch in `ls tools/arch` do [ -d tools/arch/$arch/include/uapi/asm ] || mkdir -p tools/arch/$arch/include/uapi/asm src=arch/$arch/include/uapi/asm/mman.h target=tools/arch/$arch/include/uapi/asm/mman.h.tmp real_target=tools/arch/$arch/include/uapi/asm/mman.h guard="TOOLS_ARCH_"`echo $arch | awk '{print toupper($0)}'`_UAPI_ASM_MMAN_FIX_H rm -f $target [ -f $src ] && for m in $macros do if grep '#define[ \t]*'$m $src > /dev/null 2>&1 then grep -h '#define[ \t]*'$m $src | sed 's/[ \t]*\/\*.*$//g' >> $target fi done if [ -f $src ] then grep '#include > $target else echo "#include " >> $target fi touch $real_target for m in $macros do if cat << EOF | gcc -Itools/arch/$arch/include -Itools/arch/$arch/include/uapi -Iinclude/ -Iinclude/uapi -E - | grep $m > /dev/null 2>&1 #include #include $m EOF then echo "Fixing $m for $arch" echo "/* $m is undefined on $arch, fix it for perf */" >> $target if echo $m | grep '^MADV_' > /dev/null 2>&1 then grep -h '#define[ \t]*'$m include/uapi/asm-generic/mman-common.h | sed 's/[ \t]*\/\*.*$//g' >> $target else echo "#define $m 0" >> $target fi fi done real_target=tools/arch/$arch/include/uapi/asm/mman.h echo '#ifndef '$guard > $real_target echo '#define '$guard >> $real_target cat $target | sed 's|asm-generic|uapi/asm-generic|g' >> $real_target echo '#endif' >> $real_target rm $target echo "$real_target" done exit 0 # Following macros are extracted from: # tools/perf/trace/beauty/mmap.c # # start macro list MADV_DODUMP MADV_DOFORK MADV_DONTDUMP MADV_DONTFORK MADV_DONTNEED MADV_FREE MADV_HUGEPAGE MADV_HWPOISON MADV_MERGEABLE MADV_NOHUGEPAGE MADV_NORMAL MADV_RANDOM MADV_REMOVE MADV_SEQUENTIAL MADV_SOFT_OFFLINE MADV_UNMERGEABLE MADV_WILLNEED MAP_32BIT MAP_ANONYMOUS MAP_DENYWRITE MAP_EXECUTABLE MAP_FILE MAP_FIXED MAP_GROWSDOWN MAP_HUGETLB MAP_LOCKED MAP_NONBLOCK MAP_NORESERVE MAP_POPULATE MAP_PRIVATE MAP_SHARED MAP_STACK MAP_UNINITIALIZED MREMAP_FIXED MREMAP_MAYMOVE PROT_EXEC PROT_GROWSDOWN PROT_GROWSUP PROT_NONE PROT_READ PROT_SEM PROT_WRITE Signed-off-by: Wang Nan Tested-by: Kim Phillips Tested-by: Naveen N.
