Wesley W. Terpstra dcfbdabe60 CacheCork: better document edge conditions 2018-02-15 19:14:30 -08:00
Wesley W. Terpstra ecd069dca4 tilelink: allow FIFO caches
Probably not a smart thing to build, but not illegal!

Wesley W. Terpstra acecc407a5 HellaCache: we do NOT really support probe below the block size!
If we did, you would somehow have to retain ownership of the
unprobed parts of the block, in case they happened to be dirty.

Wesley W. Terpstra fa412246b3 Error: don't be an exception wrt. caching
Prior to this PR, the error device was allowed to be cached by
multiple actors despite never probing any of them. This is a
pretty unusual set of properties that has caused us trouble
several times now in the past.

Let's instead put the Error device into one of two very well
established categories: a straight-up MMIO device or a tracked
memory region.

JTAG: Use new withClock way of overriding clocks (#1072)
* JTAG: Use new withClock way of overriding clocks

the override clock way is deprecated

* JTAG: use withClock instead of override clock

* JTAG:  extend Module for ClockedCounter

* JTAG: Don't use deprecated clock constructs

* JTAG: Remove another override_clock

* Rename "NegativeEdgeLatch"

because it's not a latch, it's just a register on the negative edge of the clock.

* Use the appropriately named NegEdgeReg

* JTAG: Rename another NegativeEdgeLatch

Schuyler Eldridge e52d52ae99 Link PlusArg to emulator command line options
- adds a mutable singleton (PlusArgArtefacts) to store information
  about Rocket PlusArgs
- adds methods to PlusArgArtefacts to emit C snippets that are
  consumed by emulator.cc for correct argument parsing and help text
  generation
- emits snippets in $(CONFIG).plusArgs via BaseCoreplex-set
  ElaborationArtefacts
- modify emulator/Makefrag-verilator to include $(CONFIG).plusArgs
- cleanup help text (docstring) for existing PlusArgs
