2012-02-11SPARC: Make PSTATE and HPSTATE a BitUnion.Gabe Black
This gets rid of cryptic bits of code with lots of bit manipulation, and makes some comments redundant.
2012-02-07Faults: Turn off arch/faults.hhGabe Black
Because there are no longer architecture independent but specialized functions in arch/XXX/faults.hh, code that isn't using the faults from a particular ISA no longer needs to be able to include them through the switching header file arch/faults.hh. By removing that header file (arch/faults.hh), the potential interface between ISA code and non ISA code is narrowed.

2012-01-31clang: Enable compiling gem5 using clang 2.9 and 3.0Koan-Sin Tan
This patch adds the necessary flags to the SConstruct and SConscript files for compiling using clang 2.9 and later (on Ubuntu et al and OSX XCode 4.2), and also cleans up a bunch of compiler warnings found by clang. Most of the warnings are related to hidden virtual functions, comparisons with unsigneds >= 0, and if-statements with empty bodies. A number of mismatches between struct and class are also fixed. clang 2.8 is not working as it has problems with class names that occur in multiple namespaces (e.g. Statistics in kernel_stats.hh). clang has a bug (http://llvm.org/bugs/show_bug.cgi?id=7247) which causes confusion between the container std::set and the function Packet::set, and this is currently addressed by not including the entire namespace std, but rather selecting e.g. "using std::vector" in the appropriate places.
2012-01-31util: implements "writefile" gem5 op to export file from guest to host ↵Dam Sunwoo
filesystem Usage: m5 writefile <filename> File will be created in the gem5 output folder with the identical filename. Implementation is largely based on the existing "readfile" functionality. Currently does not support exporting of folders.
2012-01-31CheckerCPU: Re-factor CheckerCPU to be compatible with current gem5Geoffrey Blake
Brings the CheckerCPU back to life to allow FS and SE checking of the O3CPU. These changes have only been tested with the ARM ISA. Other ISAs potentially require modification.

2012-01-30MEM: Clean-up of Functional/Virtual/TranslatingPort remnantsAndreas Hansson
This patch cleans up forward declarations and a member-function prototype that still referred to the old FunctionalPort, VirtualPort and TranslatingPort. There is no change in functionality.
2012-01-29Implement Ali's review feedback.Gabe Black
Try to decrease indentation, and remove some redundant FullSystem checks.

2012-01-17MEM: Separate queries for snooping and address rangesAndreas Hansson
This patch simplifies the address-range determination mechanism and also unifies the naming across ports and devices. It further splits the queries for determining if a port is snooping and what address ranges it responds to (aiming towards a separation of cache-maintenance ports and pure memory-mapped ports). Default behaviours are such that most ports do not have to define isSnooping, and master ports need not implement getAddrRanges.
2012-01-17MEM: Add port proxies instead of non-structural portsAndreas Hansson
Port proxies are used to replace non-structural ports, and thus enable all ports in the system to correspond to a structural entity. This has the advantage of accessing memory through the normal memory subsystem and thus allowing any constellation of distributed memories, address maps, etc. Most accesses are done through the "system port" that is used for loading binaries, debugging etc. For the entities that belong to the CPU, e.g. threads and thread contexts, they wrap the CPU data port in a port proxy. The following replacements are made: FunctionalPort > PortProxy TranslatingPort > SETranslatingPortProxy VirtualPort > FSTranslatingPortProxy --HG-- rename : src/mem/vport.cc => src/mem/fs_translating_port_proxy.cc rename : src/mem/vport.hh => src/mem/fs_translating_port_proxy.hh rename : src/mem/translating_port.cc => src/mem/se_translating_port_proxy.cc rename : src/mem/translating_port.hh => src/mem/se_translating_port_proxy.hh
2012-01-16Alpha: warn_once about broken PAL breakpoints.Steve Reinhardt
A recent changeset (aae12ce9f34c) removed support for PAL-mode breakpoints in Alpha, since it was awkward and likely unused. This patch lets a user know if they potentially run into this limitation.

2012-01-05X86 TLB: Move a DPRINTF to its correct placeNilay Vaish
The DPRINTF for doing protection checks appears after the checks have been carried out. It is possible that the function returns while the checks are being carried, in which case the printf is missed out. This patch moves the DPRINTF before the checks. --HG-- extra : rebase_source : 172896057e593022444d882ea93323a5d9f77a89

2011-12-01ARM: Add IsSerializeAfter and IsNonSpeculative flag to the syscall instruction .Ali Saidi
Squashes the subsequent instructions in O3 pipe after the service call, so that they see the effect of the system call when re-executed. This isn't really an issue with FS mode, but can show up in SE mode. --HG-- extra : rebase_source : 613a69fe1d9834261e25a8cd340aa6b47578e1fe

2011-11-03x86: Add microop for fenceNilay Vaish
This patch adds a new microop for memory barrier. The microop itself does nothing, but since it is marked as a memory barrier, the O3 CPU should flush all the pending loads and stores before the fence to the memory system.

2011-10-30System: Push boot_cpu_frequency down into the subclasses that actually use it.Gabe Black
This parameter depends on a number of coincidences to work properly. First, there must be an array assigned to system called "cpu" even though there's no parameter called that. Second, the items in the "cpu" array have to have a "clock" parameter which has a "frequency" member. This is true of the normal CPUs, but isn't true of the memory tester CPUs. This happened to work before because the memory tester CPUs were only used in SE mode where this parameter was being excluded. Since everything is being pulled into a common binary, this won't work any more. Since the boot_cpu_frequency parameter is only used by Alpha's Linux System object (and Mips's through copy and paste), the definition of that parameter is moved down to those objects specifically.
