2018-10-12mem: Expose the raw packet accessor functions.Gabe Black
This avoids a place where data has its endianness switched so that when the endianness based accessors switch it back it returns to normal. It also makes it easier to show intent when accessing single bytes where endianness doesn't matter, and there's no contextual endianness.

2018-10-12syscall_emul: update arm uname release to 3.7.0+Ciro Santilli
Trying to compile an ARM C hello world with arm-linux-gnueabihf-gcc from Ubuntu 16.04 leads to a runtime failure with se.py: FATAL: kernel too old because the glibc tests if the kernel is at least 3.2.0, and gem5 was reporting 3.0.0. Furthermore, it is hard to obtain such toolchain at all: for example crosstool-NG currently only allows for minimum kernels above 3.2.0. 3.7.0+ was chosen to match the aarch64 value, as it is likely that the level of support will be very similar. This commit does not guarantee that full 3.7.0 is supported, but it is not likely that we had full 3.0.0 support previously either. However, it is more likely that such support will be eventually achieved if users can at least try out their programs and implement the missing system calls as they are found.

2018-10-10mem-cache: Split Tags for indexing policiesDaniel R. Carvalho
Split indexing functionality from tags, so that code duplication is reduced when adding new classes that use different indexing policies, such as set associative, skewed associative or other hash-based policies. An indexing policy defines the mapping between an address' set and its physical location. For example, a conventional set assoc cache maps an address to all ways in a set using an immutable function, that is, a set x is always mapped to set x. However, skewed assoc caches map an address to a different set for each way, using a skewing function. FALRU has been left unmodified as it is a specialization with its own complexity.

2018-10-10mem-cache: Use set and way for ReplaceableEntryDaniel R. Carvalho
Replaceable entries belong to table-like structures, and therefore they should be indexable by combining a row and a column. These, using conventional cache nomenclature translate to sets and ways. Make these entries aware of their sets and ways. The idea is to make indexing policies usable by other table-like structures. In order to do so we move sets and ways to ReplaceableEntry, which will be the common base among table entries.

2018-10-09systemc: Change how the scheduler orders processes.Gabe Black
The Accellera implementation looks like it does all the methods, then all the threads, and then loops back and tries again, and there are even comments in the code that suggests that. What it actually does, however, is runs all the methods, then runs a single thread if one is waiting, and then starts over. The effect is that the scheduler will run any methods first, then run threads until a method might have become ready, and then repeat. This will actually result in more mixing of threads and methods, more context switches, and worse performance, but it makes the regressions pass more.

2018-10-09systemc: Rework how delayed sensitivities are handled.Gabe Black
Make BindInfo into a more general purpose Port class which mirrors sc_module and Module, sc_object and Object, etc. This tracks multiple bindings internally, and also pending sensitivities. Keep a global list of ports which are added in reverse order to match Accellera, and which is iterated over to finalize binding and for phase callbacks. This is as opposed to doing it one module at a time, and is to better match Accellera's ordering for the regressions. Also the sensitivity classes are now built with factory functions, which gets around problems calling virtual functions from their constructors or forgetting to having to have extra boilerplate each place they're constructed. The port class also now finalizes port or event finder sensitivities when its binding is completed, unless it's already complete in which case it does so immediately.

2018-10-09systemc: Refactor sensitivities.Gabe Black
Dynamic and Static sensitivities used to be represented by the same classes, even though they're (almost) disjoint in how they worked. Also timeouts, which can be used alongside dynamic sensitivities, were handled by the sensitivities themselves. That meant that the sensitivity mechanism had to mix in more types of behaviors, increasing complexity. Also, the non-standard timed_out function Accellera includes is harder to implement if the path for timeouts and regular sensitivities are mixed together. This change splits up dynamic and static sensitivities and splits out timeouts. It also immitates the ordering Accellera uses when going through sensitivities for an event. Static sensitivities are triggered first in reverse order (why?), and then dynamic sensitivities are triggered in what amounts to reverse order. To delete a sensitivity which has been handled, it's swapped with the one in the last position, and then the vector is truncated to drop it at the end. This has the net effect of stirring the dynamic sensitivities, and isn't easily immitated using a different approach, even if other approaches would be more straightforward.

Change the defaults in verify.py to be more like how I've been running it. This is as close of an approximation as I have to how someone else would want to run it manually. When run as part of a script, it's less cumbersome to have to add extra arguments.

2018-10-09systemc: Fortify how exceptions are caught and passed around.Gabe Black
This change tightens up exception catching and makes gem5's systemc code react to exceptions more in line with the Accellera implementation. This prevents exceptions from being caught by the pybind11 integration which makes it very difficult to see where an exception came from, and makes the output differ by including a (mostly useless) backtrace.

2018-10-09systemc: Merge stderr and stdout when running tests.Gabe Black
The golden output for tests doesn't distinguish between stderr and stdout, and by only comparing against stdout we have to throw away errors which would be good to verify we get right. Also the tests sometimes send output to stderr for no apparent reason, requiring manually patching the tests. This change adds filters for two messages which used to go to stderr in gem5 but now show up in the diffs, one that just says the simulation is starting, and the other for warns of unimplemented functionality. The second warning should be turned on at some point so we make sure everything the tests touch works and they don't just work by coincidence, but for now it introduces a lot of noise among otherwise passing tests.
