2020-01-31configs: allow fs.py and fs_bigLITTLE.py to work without M5_PATHCiro Santilli
The requirement to have an environment variable exported to run a program is not common, and many new users trip up on it. Before this commit, M5_PATH was a requirement to run those scripts, or else simulation would fail with: IOError: Can't find a path to system files. After this patch, as long as users indicate all required files with command line options, M5_PATH is not needed. This patch changes the M5_PATH semantics slightly to more closely match PATH and so be more intuitive to users: after this commit, if the given path contains a slash /, then the path is not searched for inside M5_PATH, which is exactly how PATH works. Users can then select images in the CWD with a leading ./ just as done for executables. This is backwards incompatible if users were already specifying their paths as ./, but this interface feels saner, because otherwise writing on the CLI e.g.: --disk-image path/to/my.disk would previously fail to find the disk, even if it existed, which is very counter-intuitive. The following will still fail however: --disk-image my.disk which is not ideal, but for now is a comprise between backwards compatibility of having an M5_PATH and what users expect from CLI interfaces.

2020-01-31configs: fs.py can take multiple disk images on most ISAsCiro Santilli
All ISAs except SPARC can now take multiple disk images by passing the --disk-image option multiple times. Before this patch, several ISAs automatically mounted a secondary disk called "linux-bigswap2.img", which had to be in M5_PATH even if the end user did not want more than one disk. This was the case for for example for X86 but not ARM. This change was done to: * allow ARM to have a second disk image in fs.py, which was not possible, and allow other ISAs like X86 and ARM to take any number of disk images * provide a simpler, more intuitive CLI interface that does not require magic disk images to be present in M5_PATH to work for ISAs such as X86. Linux does not need that secondary image to boot correctly, so it is more friendly to support a minimal setup that requires the least amount of binaries to boot, and let supply the second image manually only if they need it. * make fs.py --disk-image work more similarly across all ISAs SPARC was left with a single disk only because its setup was a bit more complex and would require further testing.

2020-01-13configs: Remove check for kernel in fs.py.Gabe Black
It is *not* true that a kernel is required in FS mode. For example, in SPARC, gem5 is set up to run actual system firmware which will load a kernel from the disk image. Other systems can run in a bare metal mode where they also have no kernel. If a configuration requires a kernel, it should check for it in C++ where there context lives, not globally in fs.py.

2019-12-17config: Default the indirect branch predictor to "None".Gabe Black
Other scripts (like se.py) blindly try to apply the indirect predictor if one is set. Because this option defaults to something, there's no way (as far as I know) to purposefully select nothing, and so the simulator crashes. Users shouldn't have to proactively prevent gem5 from killing itself regardless, so the default was changed to "None".

2019-12-13dev-virtio,configs: expose 9p diod virtio on ARMCiro Santilli
9p allows the guest Linux kernel to mount a host directory into the guest. This allows to very easily modify test programs after a run at the end of boot, without the need to re-insert the changes into a disk image. It is enabled on both fs.py and fs_bigLITTLE.py with the --vio-9p option. Adapted from code originally present on the wiki: http://gem5.org/WA-gem5 As documented in the CLI option help, the current setup requires the guest to know the full path to the host share, which is annoying, but overcoming that would require actually parsing a bit of the protocol rather than just forwarding everything to diod.

2019-11-27base, python: Allow dirname selection for the interpreterGiacomo Travaglini
This is the second step towards being able to run dynamically linked applications when the guest ISA != than host ISA. Once the guest interpreter is loaded to memory, we are able to redirect shared object loads through the redirectPath interface. How do we load the guest interpreter? The elf file is for example asking for the /lib/ld-linux-aarch64.so interpreter. That would point to a valid dynamic linker/loader if guest ISA == host ISA, but if we are running on X86 we should point to the guest (aarch64 in the example) toolchain wherever it is installed. This patch is adding the --interp-dir option to point to the parent folder of the guest /lib in the host fs.

2019-11-27configs: Add --redirects for syscall emulationGiacomo Travaglini
This is the first step towards being able to run dynamically linked applications when the guest ISA != than host ISA. (Like running a arm application on x86) By using the --redirects command line option it is possible to specify via CLI a set of path redirections to be used in SE mode. This is needed when running a dynamically linked binary in SE mode in a guest ISA different than the host. The linker will look for SOs (e.g. libc.so) in /lib/, but will only find the host libraries. With this option we can redirect to the guest toolchain/file system. Usage: gem5.opt [example script] --redirects /dir1=/path/to/host/dir1 \ --redirects /dir2=/path/to/host/dir2 Change-Id: I558838be2ad6802891707e9a1cc454786859db15 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/23065 Reviewed-by: Jason Lowe-Power <jason@lowepower.com> Maintainer: Jason Lowe-Power <jason@lowepower.com> Tested-by: kokoro <noreply+kokoro@google.com>

2019-10-29mem: Fix DRAM controller to operate on its own address spaceNikos Nikoleris
Typically, a memory controller is assigned an address range of the form [start, end). This address range might be interleaved and therefore only a non-continuous subset of the addresses in the address range is handed by this controller. Prior to this patch, the DRAM controller was unaware of the interleaving and as a result the address range could affect the mapping of addresses to DRAM ranks, rows and columns. This patch changes the DRAM controller, to transform the input address to a continuous range of the form [0, size). As a result the DRAM controller always operates on a dense and continuous address range regardlesss of the system configuration.

2019-10-11mem-ruby: Allow Ruby to use all replacement policies in ClassicJingQuJQ
Add support in Ruby to use all replacement policies in Classic. Furthermore, if new replacement policies are added to the Classic system, the Ruby system will recognize new policies without any other changes in Ruby system. The following list all the major changes: * Make Ruby cache entries (AbstractCacheEntry) inherit from Classic cache entries (ReplaceableEntry). By doing this, replacement policies can use cache entries from Ruby caches. AccessPermission and print function are moved from AbstractEntry to AbstractCacheEntry, so AbstractEntry is no longer needed. * DirectoryMemory and all SLICC files are changed to use AbstractCacheEntry as their cache entry interface. So do the python files in mem/slicc/ast which check the entry interface. * "main='false'" argument is added to the protocol files where the DirectoryEntry is defined. This change helps differentiate DirectoryEntry from CacheEntry because they are both the instances of AbstractCacheEntry now. * Use BaseReplacementPolicy in Ruby caches instead of AbstractReplacementPolicy so that Ruby caches will recognize the replacement policies from Classic. * Add getLastAccess() and useOccupancy() function to Classic system so that Ruby caches can use them. Move lastTouchTick to ReplacementData struct because it's needed by getLastAccess() to return the correct value. * Add a 2-dimensional array of ReplacementData in Ruby caches to store information for different replacement policies. Note that, unlike Classic caches, where policy information is stored in cache entries, the policy information needs to be stored in a new 2-dimensional array. This is due to Ruby caches deleting the cache entry every time the corresponding cache line get evicted.

2019-06-06mem: Option to toggle DRAM low-power statesMatthew Poremba
Adding an option to enable DRAM low-power states. The low power states can have a significant impact on application performance (sim_ticks) on the order of 2-3x, especially for compute-gpu apps. The options allows for it to easily be enabled/disabled to compare performance numbers. The option is disabled by default.

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.

2019-05-14mem-ruby: Hit latencies defined by the controllersTiago Muck
Removed the icache/dcache hit latency parameters from the Sequencer. They were replaced by the mandatory queue enqueue latency that is now defined by the top-level cache controller. By default, the latency is defined by the mandatory_queue_latency parameter. When the latency depends on specific protocol states or on the request type, the protocol may override the mandatoryQueueLatency function.
