2019-05-17configs: Generalize FileSystemConfig for non se.pyJason Lowe-Power
This patch updates the FileSystemConfig so it works with more kinds of config scripts (e.g., the Learning gem5 scripts). There are 4 main changes: - Added system as a parameter to the config_filesystem function so the function can search the system for the number of CPUs instead of relying on options from Options.py - Instead of calling redirect_paths everywhere config_filesystem is used, now it is implicitly called. - Cleaned up the Ruby scripts a bit to remove redundant calls to config_filesystem - Added a config_filesystem call to the Ruby Learning gem5 script (currently the only Learning gem5 script that requires it). In the future, I think it would be better to move the config_filesystem call into simulate.py, probably into the instantiate function. I tried to use the per-CPU configuration parameters instead of options from Options.py, but that's not possible until after the SimObject params have been finalized in instantiate.

2019-04-25sim-se: add a faux-filesystemDavid Hashe
This change introduces the concept of a faux-filesystem. The faux-filesystem creates a directory structure in m5out (or whatever output dir the user specifies) where system calls may be redirected. This is useful to avoid non-determinism when reading files with varying path names (e.g., variations from run-to-run if the simulation is scheduled on a cluster where paths may change). Also, this changeset allows circumventing host pseudofiles which have information specific to the host processor (such as cache hierarchy or processor information). Bypassing host pseudofiles can be useful when executing runtimes in the absence of an operating system kernel since runtimes may try to query standard files (i.e. /proc or /sys) which are not relevant to an application executing in syscall emulation mode.

2019-02-12systemc: config: Don't inject a custom argv[0] in sc_main.py.Gabe Black
argv[0] is already part of sys.argv, so we don't need to add an additional argument in front of sys.argv. The argv[0] which is used in gem5 config scripts is the name of the config script itself. While it might seem a little odd for the name of a systemc program to end in .py, it's as arbitrary as any other name, and generally shouldn't cause a problem. If some other more sophisticated mechanism for setting argv[0] is necessary, then the user can write a very slightly more complicated version of this script with additional logic.

2019-02-11systemc: configs: Add a very simple config which just runs sc_main.Gabe Black
This config will just run the sc_main function (which must have been provided in c++ somehow), passing through any of the scripts command line arguments to sc_main. Needing to do this sort of thing is common enough that there should be a canned config which supports it.

2019-02-07configs, arch-arm: Using AddrRange for Realview mem_regionsGiacomo Travaglini
Physical memory ranges are now saved in Realview objects as pairs of addresses (start address and size). This patch is substituting them with a single AddrRange object.

2019-02-07configs: Unifiy interpretation of Realview mem_regionsGiacomo Travaglini
In every arm platform which is making use of them, mem_regions are interpreted as a pair of start address and size. However arm SimpleSystem, which is using VExpress_GEM5_V1, is interpreting them as start address and end address. This patch is fixing this mismatch.

2019-01-25configs, arch-arm: don't search for default DTB and kernelCiro Santilli
Before this commit, there were default magic DTB and kernel filenames for some platforms. This was inelegant and error prone, as it refered to out-of-tree files, and set defaults which users almost always want to customize with explicit command line options. One result of this is that a wrong exception could be thrown if --kernel was given but not --machine-type, since the default machine type VExpress_EMM had a default kernel, and the code would always search for the default filename even though --kernel was given: IOError: Can't find file 'vmlinux.aarch32.ll_20131205.0-gem5' on path. The defaults existed only for older machine types, and not for the usually recommended VExpress_GEM5_V1, which suggests that this deprecation should not affect many users.
