2019-10-07kvm, arm: fix the size of MISCREG_FPSR and MISCREG_FPCRCiro Santilli
Those registers are 32-bit instead of 64 in the KVM API. The Linux kernel 5.2 linux/Documentation/virtual/kvm/api.txt contains: 0x6020 0000 0010 00d4 FPSR 32 fp_regs.fpsr 0x6020 0000 0010 00d5 FPCR 32 fp_regs.fpcr The register itself is 64-bit in the ARM manual, but the top 32 are RES0. This fixes the following error when running ARM KVM early in the simulation: panic: KVM: Failed to set register (0x60300000001000d4) value (errno: 22) Change-Id: I8fe6e12df4809992173200a42e3ce5414748bdad Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/21300 Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com> Maintainer: Andreas Sandberg <andreas.sandberg@arm.com>

2019-10-02fastmodel: Get rid of the back channel mem port in FastModel::ArmCPU.Gabe Black
This was to support port proxies and getInstPort and getDataPort. With some recent upstream changes, getInstPort and getDataPort are only used for CPU switching which we can't support (TLM ports are bound permanently), and with the sendFunctional delegate for port proxies, we don't need to have a traditional gem5 port lying around. This gets rid of the "mem" port and all its plumbing.

2019-10-02x86: Switch from MessageReq and Resp to WriteReq and Resp.Gabe Black
Originally MessageReq was intended to mark a packet as a holding a message destined for a particular recipient and which would not interact with other packets. This is similar to the way a WriteReq would behave if writing to a device register which needs to be updated atomically. Also, while the memory system *could* recognize a MessageReq and know that it didn't need to interact with other packets, that was never implemented.

2019-10-02fastmodel: Let the EVS set an attribute for getSendFunctional to return.Gabe Black
The iris CPU model doesn't necessarily know the best way to send functional packets (what port? what type is that port?), but only has a generic sc_module pointer to the EVS and so can't call specialized methods on it. There also isn't any common base class for EVSes to cast into in a generic way. This attribute mechanism lets the EVS set up its own sendFunctional implementation however it needs to using facilities that are built into generic sc_objects.

2019-10-01fastmodel: Add a gem5Cpu attribute to the CortexA76x1.Gabe Black
This attribute is to let the fast model EVS CPU find and talk to the gem5 CPU in case it needs a pointer to one of its ThreadContexts for instance. Also move the code that finds the clock period attribute/event to the constructor. gem5 guarantees that the EVS is constructed before its pointer is passed to the iris CPU wrapper, and so the EVS will have had a chance to install those controls if it's going to.

2019-10-01mem-cache: Fix invalid whenReadyDaniel R. Carvalho
When a writeback needs to be allocated the whenReady field of the block is not set, and therefore its access latency calculation uses the previously invalidated value (MaxTick), significantly delaying execution. This is fixed by assuming that the data write portion of a write access is done regardless of previous writes, and that only the tag latency is important for the critical path latency calculation.

2019-09-30misc: Added line wrapping functionality for Sim-Object descBobby R. Bruce
Descriptions were previously printed on one line, unless explicitly broken when writing the description of the Sim-Object. In this commit, line wrapping is enabled when printing these descriptions. Developers, when writing the Sim-Object descriptions, may now over multiple lines with triple double-quotes and still have the description output correctly when viewing the Sim-Objects within the CLI. E.g.: X86System previously had the following load_addr_mask component which was output as: load_addr_mask default: 18446744073709551615 desc: Address to mask loading binaries with, if 0, system \ auto-calculates the mask to be the most restrictive, otherwise it obeys a \ custom mask. This was defined by the developer via: load_addr_mask = Param.UInt64(0xffffffffffffffff, "Address to mask loading binaries with, if 0, system " "auto-calculates the mask to be the most restrictive, " "otherwise it obeys a custom mask.") This is now displayed as: load_addr_mask default: 18446744073709551615 desc: Address to mask loading binaries with, if 0, system auto-calculates the mask to be the most restrictive, otherwise it obeys a custom mask.

2019-09-30mem: Convert DRAM controller to new-style statsAndreas Sandberg
Note that this changes the stat format used by the DRAM controller. Previously, it would have a structure looking a bit like this: - system - dram: Main DRAM controller - dram_0: Rank 0 - dram_1: Rank 1 This structure can't be replicated with new-world stats since stats are confined to the SimObject name space. This means that the new structure looks like this: - system - dram: Main DRAM controller - rank0: Rank 0 - rank1: Rank 1 Change-Id: I7435cfaf137c94b0c18de619d816362dd0da8125 Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/21142 Maintainer: Nikos Nikoleris <nikos.nikoleris@arm.com> Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Daniel Carvalho <odanrc@yahoo.com.br> Reviewed-by: Wendy Elsasser <wendy.elsasser@arm.com>

2019-09-27fastmodel: Add glue code which adapts fastmodels to run in gem5.Gabe Black
Fast Models are models written by ARM which emulate different components of a computer system. They can be combined into small subsystems and then exported as systemc modules. To enable this code, you'll need to set USE_ARM_FASTMODEL variable to true. This CL does not include the fast models themselves, or a license to use them or the associated tools. To build these fast models, you'll need to set some scons variables. These variables should be set as described in the fast model distribution. * PVLIB_HOME * MAXCORE_HOME * ARMLMD_LICENSE_FILE Some minor patches to source filesdistributed with the fast model code may be necessary since their use of systemc is not necessarily 100% standards compliant.

Implement the same quirk as the original code to make sure names of old- and new-world stats are compatible.

2019-09-25mem-ruby: prevent cacheProbe being called multiple timesJing Qu
The cacheProbe() function will return the victim entry, and it gets called for multiple times in trigger function in a single miss. This will cause a problem when we try to add a new replacement policy to the Ruby system. Certain policy, like RRIP, will modify the block information every time the getVictim() function gets called. To prevent future problems, we need to store the victim entry, so that we only call it once in one miss.
