 TYPES

-Basic types (u8/u16/u32/u64/s8/s16/s32/s64) are integer types. Prefix 's' and 'u' means those types are signed and unsigned respectively. Traced arguments are shown in decimal (signed) or hex (unsigned). You can also use 's' or 'u' to specify only signedness and leave its size auto-detected by perf probe.
+Basic types (u8/u16/u32/u64/s8/s16/s32/s64) and hexadecimal integers (x8/x16/x32/x64) are integer types. Prefix 's' and 'u' means those types are signed and unsigned respectively, and 'x' means that is shown in hexadecimal format. Traced arguments are shown in decimal (sNN/uNN) or hex (xNN). You can also use 's' or 'u' to specify only signedness and leave its size auto-detected by perf probe. Moreover, you can use 'x' to explicitly specify to be shown in hexadecimal (the size is also auto-detected).
 String type is a special type, which fetches a "null-terminated" string from kernel space. This means it will fail and store NULL if the string container has been paged out. You can specify 'string' type only for the local variable or structure member which is an array of or a pointer to 'char' or 'unsigned char' type.
 Bitfield is another special type, which takes 3 parameters, bit-width, bit-offset, and container-size (usually 32). The syntax is;

+        - address filters
+
+        A hardware trace PMU advertises its ability to accept a number of
+        address filters by specifying a non-zero value in
+        /sys/bus/event_source/devices/<pmu>/nr_addr_filters.
+
+        Address filters have the format:
+
+        filter|start|stop|tracestop <start> [/ <size>] [@<file name>]
+
+        Where:
+        - 'filter': defines a region that will be traced.
+        - 'start': defines an address at which tracing will begin.
+        - 'stop': defines an address at which tracing will stop.
+        - 'tracestop': defines a region in which tracing will stop.
+
+        <file name> is the name of the object file, <start> is the offset to the
+        code to trace in that file, and <size> is the size of the region to
+        trace. 'start' and 'stop' filters need not specify a <size>.
+
+        If no object file is specified then the kernel is assumed, in which case
+        the start address must be a current kernel memory address.
+
+        <start> can also be specified by providing the name of a symbol. If the
+        symbol name is not unique, it can be disambiguated by inserting #n where
+        'n' selects the n'th symbol in address order. Alternately #0, #g or #G
+        select only a global symbol. <size> can also be specified by providing
+        the name of a symbol, in which case the size is calculated to the end
+        of that symbol. For 'filter' and 'tracestop' filters, if <size> is
+        omitted and <start> is a symbol, then the size is calculated to the end
+        of that symbol.
+
+        If <size> is omitted and <start> is '*', then the start and size will
+        be calculated from the first and last symbols, i.e. to trace the whole
+        file.
+
+        If symbol names (or '*') are provided, they must be surrounded by white
+        space.
+
+        The filter passed to the kernel is not necessarily the same as entered.
+        To see the filter that is passed, use the -v option.
+
+        The kernel may not be able to configure a trace region if it is not
+        within a single mapping.  MMAP events (or /proc/<pid>/maps) can be
+        examined to determine if that is a possibility.
+
+        Multiple filters can be separated with space or comma.
