17 * We do not have hardware single-stepping on ARM, This
18 * effort is further complicated by the ARM not having a
19 * "next PC" register. Instructions that change the PC
20 * can't be safely single-stepped in a MP environment, so
21 * we have a lot of work to do:
22 *
23 * In the prepare phase:
24 * *) If it is an instruction that does anything
25 * with the CPU mode, we reject it for a kprobe.
26 * (This is out of laziness rather than need. The
27 * instructions could be simulated.)
28 *
29 * *) Otherwise, decode the instruction rewriting its
30 * registers to take fixed, ordered registers and
31 * setting a handler for it to run the instruction.
32 *
33 * In the execution phase by an instruction's handler:
34 *
35 * *) If the PC is written to by the instruction, the
36 * instruction must be fully simulated in software.
37 * If it is a conditional instruction, the handler
38 * will use insn[0] to copy its condition code to
39 * set r0 to 1 and insn[1] to "mov pc, lr" to return.
40 *
41 * *) Otherwise, a modified form of the instruction is
42 * directly executed. Its handler calls the
43 * instruction in insn[0]. In insn[1] is a
44 * "mov pc, lr" to return.
45 *
46 * Before calling, load up the reordered registers
47 * from the original instruction's registers. If one
48 * of the original input registers is the PC, compute
49 * and adjust the appropriate input register.
50 *
51 * After call completes, copy the output registers to
52 * the original instruction's original registers.
53 *
54 * We don't use a real breakpoint instruction since that
55 * would have us in the kernel go from SVC mode to SVC
56 * mode losing the link register. Instead we use an
57 * undefined instruction. To simplify processing, the
58 * undefined instruction used for kprobes must be reserved
59 * exclusively for kprobes use.
60 *
61 * TODO: ifdef out some instruction decoding based on architecture.

391 * To avoid the complications of mimicing single-stepping on a
392 * processor without a Next-PC or a single-step mode, and to
393 * avoid having to deal with the side-effects of boosting, we
394 * simulate or emulate (almost) all ARM instructions.
395 *
396 * "Simulation" is where the instruction's behavior is duplicated in
397 * C code. "Emulation" is where the original instruction is rewritten
398 * and executed, often by altering its registers.
399 *
400 * By having all behavior of the kprobe'd instruction completed before
401 * returning from the kprobe_handler(), all locks (scheduler and
402 * interrupt) can safely be released. There is no need for secondary
403 * breakpoints, no race with MP or preemptable kernels, nor having to
404 * clean up resources counts at a later time impacting overall system
405 * performance. By rewriting the instruction, only the minimum registers
406 * need to be loaded and saved back optimizing performance.
407 *
408 * Calling the insnslot_*_rwflags version of a function doesn't hurt
409 * anything even when the CPSR flags aren't updated by the
410 * instruction. It's just a little slower in return for saving
411 * a little space by not having a duplicate function that doesn't
412 * update the flags. (The same optimization can be said for
413 * instructions that do or don't perform register writeback)
414 * Also, instructions can either read the flags, only write the
415 * flags, or read and write the flags. To save combinations
416 * rather than for sheer performance, flag functions just assume
417 * read and write of flags.

252 On AT91sam926x chips, or otherwise when using a higher precision
