and 32-bit Thumb. These tests + * fall into two categories; run_api_tests() checks basic functionality of the + * kprobes API, and run_test_cases() is a comprehensive test for kprobes + * instruction decoding and simulation. + * + * run_test_cases() first checks the kprobes decoding table for self consistency + * (using table_test()) then executes a series of test cases for each of the CPU + * instruction forms. coverage_start() and coverage_end() are used to verify + * that these test cases cover all of the possible combinations of instructions + * described by the kprobes decoding tables. + * + * The individual test cases are in kprobes-test-arm.c and kprobes-test-thumb.c + * which use the macros defined in kprobes-test.h. The rest of this + * documentation will describe the operation of the framework used by these + * test cases. + */ + +/* + * TESTING METHODOLOGY + * ------------------- + * + * The methodology used to test an ARM instruction 'test_insn' is to use + * inline assembler like: + * + * test_before: nop + * test_case: test_insn + * test_after: nop + * + * When the test case is run a kprobe is placed of each nop. The + * post-handler of the test_before probe is used to modify the saved CPU + * register context to that which we require for the test case. The + * pre-handler of the of the test_after probe saves a copy of the CPU + * register context. In this way we can execute test_insn with a specific + * register context and see the results afterwards. + * + * To actually test the kprobes instruction emulation we perform the above + * step a second time but with an additional kprobe on the test_case + * instruction itself. If the emulation is accurate then the results seen + * by the test_after probe will be identical to the first run which didn't + * have a probe on test_case. + * + * Each test case is run several times with a variety of variations in the + * flags value of stored in CPSR, and for Thumb code, different ITState. + * + * For instructions which can modify PC, a second test_after probe is used + * like this: + * + * test_before: nop + * test_case: test_insn + * test_after: nop + * b test_done + * test_after2: nop + * test_done: + * + * The test case is constructed such that test_insn branches to + * test_after2, or, if testing a conditional instruction, it may just + * continue to test_after. The probes inserted at both locations let us + * determine which happened. A similar approach is used for testing + * backwards branches... + * + * b test_before + * b test_done @ helps to cope with off by 1 branches + * test_after2: nop + * b test_done + * test_before: nop + * test_case: test_insn + * test_after: nop + * test_done: + * + * The macros used to generate the assembler instructions describe above + * are TEST_INSTRUCTION, TEST_BRANCH_F (branch forwards) and TEST_BRANCH_B + * (branch backwards). In these, the local variables numbered 1, 50, 2 and + * 99 represent: test_before, test_case, test_after2 and test_done. + * + * FRAMEWORK + * --------- + * + * Each test case is wrapped between the pair of macros TESTCASE_START and + * TESTCASE_END. As well as performing the inline assembler boilerplate, + * these call out to the kprobes_test_case_start() and + * kprobes_test_case_end() functions which drive the execution of the test + * case. The specific arguments to use for each test case are stored as + * inline data constructed using the various TEST_ARG_* macros. Putting + * this all together, a simple test case may look like: + * + * TESTCASE_START("Testing mov r0, r7") + * TEST_ARG_REG(7, 0x12345678) // Set r7=0x12345678 + * TEST_ARG_END("") + * TEST_INSTRUCTION("mov r0, r7") + * TESTCASE_END + * + * Note, in practice the single convenience macro TEST_R would be used for this + * instead. + * + * The above would expand to assembler looking something like: + * + * @ TESTCASE_START + * bl __kprobes_test_case_start + * @ start of inline data... + * .ascii "mov r0, r7" @ text title for test case + * .byte 0 + * .align 2 + * + * @ TEST_ARG_REG + * .byte ARG_TYPE_REG + * .byte 7 + * .short 0 + * .word 0x1234567 + * + * @ TEST_ARG_END + * .byte ARG_TYPE_END + * .byte TEST_ISA @ flags, including ISA being tested + * .short 50f-0f @ offset of 'test_before' + * .short 2f-0f @ offset of 'test_after2' (if relevent) + * .short 99f-0f @ offset of 'test_done' + * @ start of test case code... + * 0: + * .code TEST_ISA @ switch to ISA being tested + * + * @ TEST_INSTRUCTION + * 50: nop @ location for 'test_before' probe + * 1: mov r0, r7 @ the test case instruction 'test_insn' + * nop @ location for 'test_after' probe + * + * // TESTCASE_END + * 2: + * 99: bl __kprobes_test_case_end_##TEST_ISA + * .code NONMAL_ISA + * + * When the above is execute the following happens... + * + * __kprobes_test_case_start() is an assembler wrapper which sets up space + * for a stack buffer and calls the C function kprobes_test_case_start(). + * This C function will do some initial processing of the inline data and + * setup some global state. It then inserts the test_before and test_after + * kprobes and returns a value which causes the assembler wrapper to jump + * to the start of the test case code, (local label '0'). + * + * When the test case code executes, the test_before probe will be hit and + * test_before_post_handler will call setup_test_context(). This fills the + * stack buffer and CPU registers with a test pattern and then processes + * the test case arguments. In our example there is one TEST_ARG_REG which + * indicates that R7 should be loaded with the value 0x12345678. + * + * When the test_before probe ends, the test case continues and executes + * the "mov r0, r7" instruction. It then hits the test_after probe and the + * pre-handler for this (test_after_pre_handler) will save a copy of the + * CPU register context. This should now have R0 holding the same value as + * R7. + * + * Finally we get to the call to __kprobes_test_case_end_{32,16}. This is + * an assembler wrapper which switches back to the ISA used by the test + * code and calls the C function kprobes_test_case_end(). + * + * For each run through the test case, test_case_run_count is incremented + * by one. For even runs, kprobes_test_case_end() saves a copy of the + * register and stack buffer contents from the test case just run. It then + * inserts a kprobe on the test case instruction 'test_insn' and returns a + * value to cause the test case code to be re-run. + * + * For odd numbered runs, kprobes_test_case_end() compares the register and + * stack buffer contents to those that were saved on the previous even + * numbered run (the one without the kprobe on test_insn). These should be + * the same if the kprobe instruction simulation routine is correct. + * + * The pair of test case runs is repeated with different combinations of + * flag values in CPSR and, for Thumb, different ITState. This is + * controlled by test_context_cpsr(). + * + * BUILDING TEST CASES + * ------------------- + * + * + * As an aid to building test cases, the stack buffer is initialised with + * some special values: + * + * [SP+13*4] Contains SP+120.

Enabling this option requires - that all other hardware types must be disabled, as Sun 3 kernels - are incompatible with all other m68k targets (including Sun 3x!). - - If you don't want to compile a kernel exclusively for a Sun 3, say N. - -config NATFEAT - bool "ARAnyM emulator support" - depends on ATARI - help - This option enables support for ARAnyM native features, such as - access to a disk image as /dev/hda. - -config NFBLOCK - tristate "NatFeat block device support" - depends on BLOCK && NATFEAT - help - Say Y to include support for the ARAnyM NatFeat block device - which allows direct access to the hard drives without using - the hardware emulation. - -config NFCON - tristate "NatFeat console driver" - depends on NATFEAT - help - Say Y to include support for the ARAnyM NatFeat console driver - which allows the console output to be redirected to the stderr - output of ARAnyM. - -config NFETH - tristate "NatFeat Ethernet support" - depends on NET_ETHERNET && NATFEAT - help - Say Y to include support for the ARAnyM NatFeat network device - which will emulate a regular ethernet device while presenting an - ethertap device to the host system. - -comment "Processor type" - -config M68020 - bool "68020 support" - help - If you anticipate running this kernel on a computer with a MC68020 - processor, say Y. Otherwise, say N. Note that the 68020 requires a - 68851 MMU (Memory Management Unit) to run Linux/m68k, except on the - Sun 3, which provides its own version. - -config M68030 - bool "68030 support" - depends on !MMU_SUN3 - help - If you anticipate running this kernel on a computer with a MC68030 - processor, say Y. Otherwise, say N. Note that a MC68EC030 will not - work, as it does not include an MMU (Memory Management Unit). - -config M68040 - bool "68040 support" - depends on !MMU_SUN3 - help - If you anticipate running this kernel on a computer with a MC68LC040 - or MC68040 processor, say Y. Otherwise, say N. Note that an - MC68EC040 will not work, as it does not include an MMU (Memory - Management Unit). - -config M68060 - bool "68060 support" - depends on !MMU_SUN3 - help - If you anticipate running this kernel on a computer with a MC68060 - processor, say Y. Otherwise, say N. - -config MMU_MOTOROLA - bool - -config MMU_SUN3 - bool - depends on MMU && !MMU_MOTOROLA - -config M68KFPU_EMU - bool "Math emulation support (EXPERIMENTAL)" - depends on EXPERIMENTAL - help - At some point in the future, this will cause floating-point math - instructions to be emulated by the kernel on machines that lack a - floating-point math coprocessor. Thrill-seekers and chronically - sleep-deprived psychotic hacker types can say Y now, everyone else - should probably wait a while. - -config M68KFPU_EMU_EXTRAPREC - bool "Math emulation extra precision" - depends on M68KFPU_EMU - help - The fpu uses normally a few bit more during calculations for - correct rounding, the emulator can (often) do the same but this - extra calculation can cost quite some time, so you can disable - it here. The emulator will then "only" calculate with a 64 bit - mantissa and round slightly incorrect, what is more than enough - for normal usage. - -config M68KFPU_EMU_ONLY - bool "Math emulation only kernel" - depends on M68KFPU_EMU - help - This option prevents any floating-point instructions from being - compiled into the kernel, thereby the kernel doesn't save any - floating point context anymore during task switches, so this - kernel will only be usable on machines without a floating-point - math coprocessor. This makes the kernel a bit faster as no tests - needs to be executed whether a floating-point instruction in the - kernel should be executed or not. - -config ADVANCED - bool "Advanced configuration options" - ---help--- - This gives you access to some advanced options for the CPU. The - defaults should be fine for most users, but these options may make - it possible for you to improve performance somewhat if you know what - you are doing. - - Note that the answer to this question won't directly affect the - kernel: saying N will just cause the configurator to skip all - the questions about these options. - - Most users should say N to this question. - -config RMW_INSNS - bool "Use read-modify-write instructions" - depends on ADVANCED - ---help--- - This allows to use certain instructions that work with indivisible - read-modify-write bus cycles. While this is faster than the - workaround of disabling interrupts, it can conflict with DMA - ( = direct memory access) on many Amiga systems, and it is also said - to destabilize other machines. It is very likely that this will - cause serious problems on any Amiga or Atari Medusa if set. The only - configuration where it should work are 68030-based Ataris, where it - apparently improves performance. But you've been warned! Unless you - really know what you are doing, say N. Try Y only if you're quite - adventurous. - -config SINGLE_MEMORY_CHUNK - bool "Use one physical chunk of memory only" if ADVANCED && !SUN3 - default y if SUN3 - select NEED_MULTIPLE_NODES - help - Ignore all but the first contiguous chunk of physical memory for VM - purposes. This will save a few bytes kernel size and may speed up - some operations. Say N if not sure. - -config 060_WRITETHROUGH - bool "Use write-through caching for 68060 supervisor accesses" - depends on ADVANCED && M68060 - ---help--- - The 68060 generally uses copyback caching of recently accessed data. - Copyback caching means that memory writes will be held in an on-chip - cache and only written back to memory some time later. Saying Y - here will force supervisor (kernel) accesses to use writethrough - caching. Writethrough caching means that data is written to memory - straight away, so that cache and memory data always agree. - Writethrough caching is less efficient, but is needed for some - drivers on 68060 based systems where the 68060 bus snooping signal - is hardwired on. The 53c710 SCSI driver is known to suffer from - this problem. - -config ARCH_DISCONTIGMEM_ENABLE - def_bool !SINGLE_MEMORY_CHUNK - -config NODES_SHIFT - int - default "3" - depends on !SINGLE_MEMORY_CHUNK - -config ZORRO - bool "Amiga Zorro (AutoConfig) bus support" - depends on AMIGA - help - This enables support for the Zorro bus in the Amiga. If you have - expansion cards in your Amiga that conform to the Amiga - AutoConfig(tm) specification, say Y, otherwise N. Note that even - expansion cards that do not fit in the Zorro slots but fit in e.g. - the CPU slot may fall in this category, so you have to say Y to let - Linux use these. - -config AMIGA_PCMCIA - bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)" - depends on AMIGA && EXPERIMENTAL - help - Include support in the kernel for pcmcia on Amiga 1200 and Amiga - 600. If you intend to use pcmcia cards say Y; otherwise say N. - -config HEARTBEAT - bool "Use power LED as a heartbeat" if AMIGA || APOLLO || ATARI || MAC ||Q40 - default y if !AMIGA && !APOLLO && !ATARI && !MAC && !Q40 && HP300 - help - Use the power-on LED on your machine as a load meter. The exact - behavior is platform-dependent, but normally the flash frequency is - a hyperbolic function of the 5-minute load average. - -# We have a dedicated heartbeat LED. :-) -config PROC_HARDWARE - bool "/proc/hardware support" - help - Say Y here to support the /proc/hardware file, which gives you - access to information about the machine you're running on, - including the model, CPU, MMU, clock speed, BogoMIPS rating, - and memory size. - -config ISA - bool - depends on Q40 || AMIGA_PCMCIA - default y - help - Find out whether you have ISA slots on your motherboard. ISA is the - name of a bus system, i.e. the way the CPU talks to the other stuff - inside your box. Other bus systems are PCI, EISA, MicroChannel - (MCA) or VESA. ISA is an older system, now being displaced by PCI; - newer boards don't support it. If you have ISA, say Y, otherwise N. - -config GENERIC_ISA_DMA - bool - depends on Q40 || AMIGA_PCMCIA - default y - -source "drivers/pci/Kconfig" - -source "drivers/zorro/Kconfig" - diff --git a/arch/m68k/Makefile b/arch/m68k/Makefile index be46cadd4017..cf318f20c64d 100644 --- a/arch/m68k/Makefile +++ b/arch/m68k/Makefile @@ -1,7 +1,171 @@ +# +# m68k/Makefile +# +# This file is included by the global makefile so that you can add your own +# architecture-specific flags and dependencies.
