2019-05-21sim-se: change syscall function signatureBrandon Potter
The system calls had four parameters. One of the parameters is ThreadContext and another is Process. The ThreadContext holds the value of the current process so the Process parameter is redundant since the system call functions already have indirect access. With the old API, it is possible to call into the functions with the wrong supplied Process which could end up being a confusing error. This patch removes the redundancy by forcing access through the ThreadContext field within each system call.

That piece of the tree can also be called from thumb which decodes it in the same way, although the thumb decode table has a different terminology The old code didn't match neither A32 or T32 terminologies, so it is better to at least match one of them to help verify correctness.

2019-05-03arch-riscv,isa: Fix for compressed jump (c_j) immAvishai Tvila
c_j(al) has a special format, called CJ. The jump offset format is instbits[12:2] --> offset[11|4|9:8|10|6|7|3:1|5] Currently in decoder.isa, c_j format is JOp, the imm and branchTarget are incorrect In the execute section (decoder.isa:228), the imm fields is ignored and the offset is calculated correctlly. As a result, we get decoder flush for each c_j instance I've added CJOp format in compressed.isa, and use it in execute section. In addition, c_j is mappped to jal zero, cj_imm, and actually is neither indirect control nor a function call I fixed the flags accordently. I'll fix all IsRet, IsCall and IsIndirectControl flags for rest of (c_)jal(r) in my next commit. I ran coremark -O0 before my fix and I got 37.7% branch miss-rate, after the fix the branch miss-rate is <13% Change-Id: I608d5894a78a1ebefe36f21e21aaea68b42bccfc Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/17808 Maintainer: Jason Lowe-Power <jason@lowepower.com> Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Reviewed-by: Alec Roelke <alec.roelke@gmail.com>

2019-04-29mips: Implement readRegOtherThread and setRegOtherThread directly.Gabe Black
These accessors can be implemented as helper functions within MIPS without having to plumb them through a bunch of common interfaces. There are a few problems with the way they were implemented which are carried forward to this new implementation as well. That includes hiding the register accesses from the ISA parser and therefore the CPU's dependency tracking, potentially panicing or accessing a non existent thread based on a possible set of input values, and modifying register values even if an instruction is being executed speculatively. Fixing these problems would be fairly involved and require changing how dependencies are tracked in all the CPUs so that they can act across threads, and also how registers are handled in the ISA description itself. The original implementation just punted on making this work in CPUs other than the minor CPU (and potentially one or more CPU models that were not and/or are not in the code base). Where as that implementation might have paniced if these methods were called, this will attempt to work, but may have incorrect behavior based on the limitations described above. I'd consider this an acceptable tradeoff, at least for the time being.

The AuxVector type has a bunch of accessors which just give access to the underlying variables through references. We might as well just make those members accessible directly. Also, the AuxVector doesn't need to handle endianness flips itself. We can tell the byteswap mechanism how to flip an AuxVector, and let it handle that for us. This gets rid of the entire .cc file which was complicated by trying to both hide the ISA specific endianness translations, and instantiate templated functions in a .cc.

2019-04-25arch-arm: Remove un-needed hyp flag in TLBI operationsGiacomo Travaglini
The hyp flag was probably a legacy pre-v8 flag distinguishing invalidation targeting PL2 translation regime (hyp mode). Since the introduction of target_el parameter, hyp boolean is not needed anymore. The patch works by setting the hyp flag in the flush* methods in the TLB automatically by checking if target_el == EL2.

2019-04-22sim-se: Enhance clone for X86KvmCPUAlexandru Dutu
This changeset enables clone to work with X86KvmCPU model, which will allow running multi-threaded applications at near hardware speeds. Even though the application is multi-threaded, the KvmCPU model uses one event queue, therefore, only one hardware thread will be used, through KVM, to simulate multiple application threads.
