2016-01-24MIPS: Add support for PIC32MZDA platformJoshua Henderson
This adds support for the Microchip PIC32 MIPS microcontroller with the specific variant PIC32MZDA. PIC32MZDA is based on the MIPS m14KEc core and boots using device tree. This includes an early pin setup and early clock setup needed prior to device tree being initialized. In additon, an interface is provided to synchronize access to registers shared across several peripherals.

2016-01-24MIPS: math-emu: Make microMIPS branch delay slot emulation workMaciej W. Rozycki
Complement commit 102cedc32a6e ("MIPS: microMIPS: Floating point support.") which introduced microMIPS FPU emulation, but did not adjust the encoding of the BREAK instruction used to terminate the branch delay slot emulation frame. Consequently the execution of any such frame is indeterminate and, depending on CPU configuration, will result in random code execution or an offending program being terminated with SIGILL. This is because the regular MIPS BREAK instruction is encoded with the 0 major and the 0xd minor opcode, however in the microMIPS instruction set this major/minor opcode pair denotes an encoding reserved for the DSP ASE. Instead the microMIPS BREAK instruction is encoded with the 0 major and the 0x7 minor opcode. Use the correct BREAK encoding for microMIPS FPU emulation then. Signed-off-by: Maciej W.

2016-01-24MIPS: math-emu: Correctly handle NOP emulationMaciej W. Rozycki
Fix an issue introduced with commit 9ab4471c9f1b ("MIPS: math-emu: Correct delay-slot exception propagation") where the emulation of a NOP instruction signals the need to terminate the emulation loop. This in turn, if the PC has not changed from the entry to the loop, will cause the kernel to terminate the program with SIGILL. Consider this program: static double div(double d) { do d /= 2.0; while (d > .5); return d; } int main(int argc, char **argv) { return div(argc); } which gets compiled to the following binary code: 00400490 <main>: 400490: 44840000 mtc1 a0,$f0 400494: 3c020040 lui v0,0x40 400498: d44207f8 ldc1 $f2,2040(v0) 40049c: 46800021 cvt.d.w $f0,$f0 4004a0: 46220002 mul.d $f0,$f0,$f2 4004a4: 4620103c c.lt.d $f2,$f0 4004a8: 4501fffd bc1t 4004a0 <main+0x10> 4004ac: 00000000 nop 4004b0: 4620000d trunc.w.d $f0,$f0 4004b4: 03e00008 jr ra 4004b8: 44020000 mfc1 v0,$f0 4004bc: 00000000 nop Where the FPU emulator is used, depending on the number of command-line arguments this code will either run to completion or terminate with SIGILL. If no arguments are specified, then BC1T will not be taken, NOP will not be emulated and code will complete successfully. If one argument is specified, then BC1T will be taken once and NOP will be emulated. At this point the entry PC value will be 0x400498 and the new PC value, set by `mips_dsemul' will be 0x4004a0, the target of BC1T. The emulation loop will terminate, but SIGILL will not be issued, because the PC has changed. The FPU emulator will be entered again and on the second execution BC1T will not be taken, NOP will not be emulated and code will complete successfully. If two or more arguments are specified, then the first execution of BC1T will proceed as above. Upon reentering the FPU emulator the emulation loop will continue to BC1T, at which point the branch will be taken and NOP emulated again. At this point however the entry PC value will be 0x4004a0, the same as the target of BC1T. This will make the emulator conclude that execution has not advanced and therefore an unsupported FPU instruction has been encountered, and SIGILL will be sent to the process. Fix the problem by extending the internal API of `mips_dsemul', making it return -1 if no delay slot emulation frame has been made, the instruction has been handled and execution of the emulation loop needs to continue as if nothing happened. Remove code from `mips_dsemul' to reproduce steps made by the emulation loop at the conclusion of each iteration, as those will be reached normally now. Adjust call sites accordingly. Document the API. Signed-off-by: Maciej W.

2016-01-24MIPS: sync-r4k: reduce skew while synchronizationHuacai Chen
While synchronization, count register will go backwards for the master. If synchronise_count_master() runs before synchronise_count_slave(), skew becomes even more. The skew is very harmful for CPU hotplug (CPU0 do synchronization with CPU1, then CPU0 do synchronization with CPU2 and CPU0's count goes backwards, so it will be out of sync with CPU1). After the commit cf9bfe55f24973a8f40e2 (MIPS: Synchronize MIPS count one CPU at a time), we needn't evaluate count_reference at the beginning of synchronise_count_master() any more. Thus, we evaluate the initcount (It seems like count_reference is redundant) in the 2nd loop. Since we write the count register in the last loop, we don't need additional barriers (the existing memory barriers are enough). Moreover, I think we loop 3 times is enough to get a primed instruction cache, this can also get less skew than looping 5 times. Comments are also updated in this patch.

2016-01-23pmem: add wb_cache_pmem() to the PMEM APIRoss Zwisler
__arch_wb_cache_pmem() was already an internal implementation detail of the x86 PMEM API, but this functionality needs to be exported as part of the general PMEM API to handle the fsync/msync case for DAX mmaps. One thing worth noting is that we really do want this to be part of the PMEM API as opposed to a stand-alone function like clflush_cache_range() because of ordering restrictions. By having wb_cache_pmem() as part of the PMEM API we can leave it unordered, call it multiple times to write back large amounts of memory, and then order the multiple calls with a single wmb_pmem().

2016-01-22MIPS: hpet: Choose a safe value for the ETIME checkHuacai Chen
This patch is borrowed from x86 hpet driver and explaind below: Due to the overly intelligent design of HPETs, we need to workaround the problem that the compare value which we write is already behind the actual counter value at the point where the value hits the real compare register. This happens for two reasons: 1) We read out the counter, add the delta and write the result to the compare register. When a NMI hits between the read out and the write then the counter can be ahead of the event already. 2) The write to the compare register is delayed by up to two HPET cycles in AMD chipsets. We can work around this by reading back the compare register to make sure that the written value has hit the hardware. But that is bad performance wise for the normal case where the event is far enough in the future. As we already know that the write can be delayed by up to two cycles we can avoid the read back of the compare register completely if we make the decision whether the delta has elapsed already or not based on the following calculation: cmp = event - actual_count; If cmp is less than 64 HPET clock cycles, then we decide that the event has happened already and return -ETIME. That covers the above #1 and #2 problems which would cause a wait for HPET wraparound (~306 seconds).

2016-01-22MIPS: Loongson-3: Fix SMP_ASK_C0COUNT IPI handlerHuacai Chen
When Core-0 handle SMP_ASK_C0COUNT IPI, we should make other cores to see the result as soon as possible (especially when Store-Fill-Buffer is enabled). Otherwise, C0_Count syncronization makes no sense. BTW, array is more suitable than per-cpu variable for syncronization, and there is a corner case should be avoid: C0_Count of Core-0 can be really 0.

2016-01-21Merge branch 'uaccess' (batched user access infrastructure)Linus Torvalds
Expose an interface to allow users to mark several accesses together as being user space accesses, allowing batching of the surrounding user space access markers (SMAP on x86, PAN on arm64, domain register switching on arm). This is currently only used for the user string lenth and copying functions, where the SMAP overhead on x86 drowned the actual user accesses (only noticeable on newer microarchitectures that support SMAP in the first place, of course). * user access batching branch: Use the new batched user accesses in generic user string handling Add 'unsafe' user access functions for batched accesses x86: reorganize SMAP handling in user space accesses
