See ucb-bar#1079. This option ceased doing things after Java 8 (released in 2014), and openJDK considers having it included an error.
This commit is a redo of a previous one.
* Set JAVA_TOOL_OPTIONS environment variable instead of nonstandard JAVA_OPTS
The JAVA_TOOL_OPTIONS environment variable is passed to all Java processes.
This is useful for Java processes that somehow miss the flags passed in via command line, in particular, the JVM launched by initialization of the SBT thin client only sees flags passed in by JAVA_TOOL_OPTIONS.
* Update CI with JAVA_TOOL_OPTIONS
The Java protoc plugin (part of FIRRTL) by default caches protoc in /tmp, and does not delete it afterwards.
This causes permissions failures when multiple users try to install Chipyard on the same machine, due to permissions failures over accessing the same cache in /tmp.
A solution is to place the tmpdir within the Chipyard repo. No other files besides protocjar.webcache currently use that directory, so I believe this should be safe.
[WIP] Minimally elaborating design
Bring up a feature-complete Chipyard stage
Pull in Makefrag generation; Bump submodules
Update config generation, and global reset scheme
Bump submodules; clean up
Bump FireSim
Remove some unhygenic comments / WS
Remove the rocketchip subproject
[CI] Lengthen ariane tests timeout
Address some remaining reviewer comments
[firechip] Refresh a Field that cannot be used across repeated instantiations
Bump all submodules
This adds an additional layer (ChipTop) between the System module and the TestHarness. The IOBinder API is now changed to take only a single parameter (an Any) and return a 3 things: The IO port(s), the IO cell(s), and a function to call inside the test harness, which is analogous to the old IOBinder function, except that it takes a TestHarness object as an argument instead of (clock, reset, success).
* A new Top-level module, ChipTop, has been created. ChipTop instantiates a "system" module specified by BuildSystem.
* BuildTop now builds a ChipTop dut module in the TestHarness by default
* A new BuildSystem key has been added, which by default builds DigitalTop (previously just called Top)
* The IOBinders API has changed. IOBinders are now called inside of ChipTop and return a tuple3 of (IO ports, IO cells, harness functions). The harness functions are now called inside the TestHarness (this is analogous to the previous IOBinder functions).
* IO cell models have been included in ChipTop. These can be replaced with real IO cells for tapeout, or used as-is for simulation.
* The default for the TOP make variable is now ChipTop (was Top)
* [make] split up specific make vars/targets into frags
