2019-01-23systemc: Fix TLM related includes.Gabe Black
There are a couple things this CL fixes related to the TLM #includes. 1. Removes #includes of <systemc> and <tlm>. These bring in a header file from boost which shouldn't be necessary but which some of the tests (and likely some external code) depends on. We avoid including those in files built into gem5 itself so that gem5 isn't dependent on boost. 2. All includes in ext should be relative. That way those headers can be removed from gem5 and still build, allowing them to be moved over to or referenced from a foreign codebase which isn't part of gem5.

2019-01-09systemc: Remove the TLM dependence on a non-standard method.Gabe Black
The sc_event_finder class in Accellera's implementation has a non-standard report_error function that it uses internally. The TLM headers were calling that function in their own event finder subclass. This change replaces that call with what should be an equivalent bit of code which is based on the report_error implementation.

2018-12-18systemc: Ensure resets and edges are notified when signaling a change.Gabe Black
Boolean sc_buffers (either pure bool or sc_dt::sc_logic) should signal positive and negative edges and resets even when their value doesn't change, unlike sc_signals. The spec doesn't actually say that and just mentions the value changed event, but it may have been implied that the other types of events also happen, they just made special mention of the value change event. This change moves some code around a bit so that when _signalChange() is called, if the underlying type is a boolean signal, it will automatically notify the appropriate edge event and signal any reset. Putting the functionality in _signalChange instead of delegating it to the sc_buffer lets us have a single template for sc_buffer and makes the base class template specialization handle whether the edge events exist, and if so which should be notified.

The sc_in bind function was hiding the one from sc_port by changing the const-ness of its parameter. This change explicitly exposes the underlying sc_port version, and keeps it alongside the new sc_in version. This seems mildly dangerous and undesirable because now there are two very similar functions which would both need to be overridden in order to get new behavior, but I don't think it's any more dangerous and undesirable than as (perhaps unintentionally) specified in the standard.

We have to hope systemc code doesn't play around with sc_bind_proxy too much and doesn't accidentally use this constructor unintentionally, but it seems like the least bad possible solution which makes clang happy.

2018-10-16systemc: Change how signal based resets work.Gabe Black
The previous implementation used the value changed event to track when signals changed value, but there were a couple problems with this approach. First, this piggybacked on the sensitivity mechanism in some ways, but diverged in others. The sensitivity didn't notify a process when it was satisfied like other sensitivity types would, and it also ignored whether the process was disabled. Second, the value_changed_event is notified by a signal instance as a delta notification, but reset signals are supposed to act immediately. That means they should happen before all delta notifications, or in other words all delta notifications should see the reset status of a given process. That's particularly important in the case of wait(int n) where setting the reset clears the reset count, and the count is checked when determining whether or not to wake up a process when its sensitivity is satisfied, potentially by a delta notification. Third, by removing the middle man and not trying to repurpose the sensitivity mechanism, the code gets simpler and easier to understand.

2018-10-16systemc: Implement signal based resets.Gabe Black
The implementation is based on sc_event sensitivities. Also of note is that the way reset works in the Accellera implementation isn't consistent with the spec. That says that wait(int n) is supposed to be equivalent to calling wait() n times, assuming n is greater than 0. Instead, Accellera stores that count and then doesn't wake up the process until the count is 0, decrementing it otherwise. That means that when the process is in reset, it won't actually reset for those intermediate wait()s which it would if wait() was called repeatedly. Also, oddly, when a reset becomes asserted, it will clear the count to 0 explicitly. That may have been an attempt to make the behavior of wait(int n) match the spec, but it doesn't handle cases where the reset is already set when wait(int n) is called.
