GCC's __builtin_prefetch() was introduced a long time ago, all supported GCC versions have it. Lets do what the big boys up in linux/prefetch.h do, except we use '1' as the third parameter to provoke 'PREF 0,...' and 'PREF 1,...' instead of other prefetch hints. This allows for better code generation. In theory the existing embedded asm could be optimized, but the compiler has these builtins, so there is really no point.

ar7_regiser_devices needs ar7_clocks_init to have been called first, however clock.o is currently linked later due to its order in the Makefile, therefore ar7_clocks_init always gets called later than ar7_register_devices because both have the same initcall level. Fix this by moving ar7_register_devices to the right initcall level. Reported-by: NMichael J.

The "nofpu" and "nodsp" kernel command line options currently do not affect CPUs that are brought online later in the boot process or hotplugged at runtime.

The only way the debugger can handle a trap in inside rcu_lock, notify_die, or atomic_notifier_call_chain without a recursive fault is to have a low level "first opportunity handler" do_trap_or_bp() handler. Generally this will be something the vast majority of folks will not need, but for those who need it, it is added as a kernel .config option called KGDB_LOW_LEVEL_TRAP. Also added was a die notification for oops such that kdb can catch an oops for analysis. There appeared to be no obvious way to pass the struct pt_regs from the original exception back to the stack back tracer, so a special case was added to show_stack() for when kdb is active because you generally desire to generally look at the back trace of the original exception.

These are the minimum changes to the kgdb core in order to enable an API to connect a new front end (kdb) to the debug core. This patch introduces the dbg_kdb_mode variable controls where the user level I/O is routed. It will be routed to the gdbstub (kgdb) or to the kdb front end which is a simple shell available over the kgdboc connection. You can switch back and forth between kdb or the gdb stub mode of operation dynamically. From gdb stub mode you can blindly type "$3#33", or from the kdb mode you can enter "kgdb" to switch to the gdb stub. The logic in the debug core depends on kdb to look for the typical gdb connection sequences and return immediately with KGDB_PASS_EVENT if a gdb serial command sequence is detected. That should allow a reasonably seamless transition between kdb -> gdb without leaving the kernel exception state. The two gdb serial queries that kdb is responsible for detecting are the "?" and "qSupported" packets.

由 Shane McDonald 提交于
In the FPU emulator code of the MIPS, the Cause bits of the FCSR register are not currently writeable by the ctc1 instruction. In odd corner cases, this can cause problems. For example, a case existed where a divide-by-zero exception was generated by the FPU, and the signal handler attempted to restore the FPU registers to their state before the exception occurred. In this particular setup, writing the old value to the FCSR register would cause another divide-by-zero exception to occur immediately. The solution is to change the ctc1 instruction emulator code to allow the Cause bits of the FCSR register to be writeable. This is the behaviour of the hardware that the code is emulating. This problem was found by Shane McDonald, but the credit for the fix goes to Kevin Kissell. In Kevin's words: I submit that the bug is indeed in that ctc_op: case of the emulator. The Cause bits (17:12) are supposed to be writable by that instruction, but the CTC1 emulation won't let them be updated by the instruction. I think that actually if you just completely removed lines 387-388 [...] things would work a good deal better. At least, it would be a more accurate emulation of the architecturally defined FPU. If I wanted to be really, really pedantic (which I sometimes do), I'd also protect the reserved bits that aren't necessarily writable.

The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds in the kernel and binutils. This issue has been rectified in Loongson 2F series 2F03 so no workarounds needed. Now that the workarounds [1] adding the the -mfix-loongson2f-nop and -mfix-loongson2f-jump options have been comitted to the binutils the CVS repository), we can add the workarounds in the kernel. The workarounds have no significant side effect on the system but may decrease performance so we control them through a a new CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable it as necessary.
