+@subsection Register Names
+
+@cindex BPF register names
+@cindex register names, BPF
+The eBPF processor provides ten general-purpose 64-bit registers,
+which are read-write, and a read-only frame pointer register:
+
+@table @samp
+@item %r0 .. %r9
+General-purpose registers.
+@item %r10
+Frame pointer register.
+@end table
+
+Some registers have additional names, to reflect their role in the
+eBPF ABI:
+
+@table @samp
+@item %a
+This is @samp{%r0}.
+@item %ctx
+This is @samp{%r6}.
+@item %fp
+This is @samp{%r10}.
+@end table
+
+@node BPF-Pseudo-Maps
+@subsection Pseudo Maps
+
+@cindex pseudo map fd, BPF
+The @samp{LDDW} instruction can take a literal pseudo map file
+descriptor as its second argument. This uses the syntax
+@samp{%map_fd(N)} where @samp{N} is a signed number.
+
+For example, to load the address of the pseudo map with file
+descriptor @samp{2} in register @samp{r1} we would do:
+
+@smallexample
+ lddw %r1, %map_fd(2)
+@end smallexample

+
+@subsubsection Jump instructions
+
+eBPF provides the following compare-and-jump instructions, which
+compare the values of the two given registers, or the values of a
+register and an immediate, and perform a branch in case the comparison
+holds true.
+
+@table @code
+@item ja %d,(%s|imm32),disp16
+Jump-always.
+@item jeq %d,(%s|imm32),disp16
+Jump if equal.
+@item jgt %d,(%s|imm32),disp16
+Jump if greater.
+@item jge %d,(%s|imm32),disp16
+Jump if greater or equal.

+function identified by @emph{imm32}.
+@end table

+Finally:
+
+@table @code
+@item exit
+Terminate the eBPF program.
+@end table

+
+Atomic exchange-and-add instructions are provided in two flavors: one
