As discussed in #2775 (comment) , this pr enables gdb back on the toolchain build scripts. It also updates the README to use the current toolchain name for the gdb section.
- FIX: Replace riscv_pkg:VLEN by CVA6Cfg.VLEN
- Declare VLEN as new CVA6 parameter
- smoke-hwconfig: run with vcs-uvm and use return0 tests to speed-up CI light stage timing execution
- Use dedicated linker scripts for 65x configuration.
- Use dedicated spike.yaml for 65x configuration.
- Set BHTEntries=128, cache=WT, scoreboard entries=8 to improve Coremark and Dhrystone results
- Run 4 iterations of coremark to improve results
* Clean-up README.md and top-level directory
This removes the duplicate `scripts` and `util` directories. Furthermore
the README is condensed by collapsing the citation and adding the
CITATION file to the repository.

* Re-name icache req/rsp structs
The structs used to communicate with the icache have contained the
direction, which makes no sense for structs since they inherently don't
have any direction.

* Summary: initial dromajo integration
* some changes to Makefile to enable `make verilate DROMAJO=1`
* adding ifdefs to ariane_tb.cpp to disable HTIF
* adding dromajo repo
* making dromajo repo a submodule
* syncing with upstream
* bumping to the latest dromajo commit
* Summary: adding DPI functions for cosim
* added new file tb/dpi/dromajo_cosim.cc that contains
all DPIs for dromajo to work
* editted Makefile to see the above file
* Summary: fixing build issues
* fixing syntax errors in dpi file
* renaming dpi file due to name conflict with shared library
* fixing path in Makefile to the shared dromajo lib
* bumping to the latest dromajo change
* Summary: loading checkpoint to bootrom
This change adds `+checkpoint=` argument to the verilator simulator
as well as corresponding changes to load the dromajo checkpoint into
the bootrom. Dromajo checkpoint bootcode contains series of csrw and
immediate loads to restore the architectural state of the processor.
dromajo_bootrom.sv
is a copy of a generated bootrom.sv file. This
file parses the verilog plusargs and loads the bootrom with the code
that is pointed by the +checkpoint.
csr_regfile.sv
Dromajo needs to start running the code in debug mode. The default
value of debug_mode_q was changed to 1.
* updating dromajo to the latest change
* Summary: sync main memories of dromajo and ariane
These changes load the checkpoint into the main memory of Ariane.
The checkpointed memory that is dumped from dromajo contains
(1) the binary and (2) the values of all stores that dromajo
globally performed before dumping the checkpoint.
dromajo_ram.sv
This file is a copy of SyncSpRamBeNx64.sv and was modified to parse
+checkpoint argument to load the memory from the path pointed by
the argument.
The remaining changes were introduced to instantiate the above file
when DROMAJO=1 flag is set.
* Summary: calling DPIs for cosimulation
This change introduces the calls to DPI functions that interface
with Dromajo.
* updating to the latest commit of dromajo
* disabling verbose output when preloading bootrom and mainram
* Summary: bug fix - update logic of `dcsr_d.prv`
This change was made per discussion with Florian via email. The
current versionincorrectly implements the update logic of
`dcsr_d.prv`.
The confusion came from the fact that the core should update its
`dcsr_d.prv` to the current running privilege level when entering
debug mode. I've attached a patch which, as you suggested, removes
the wrong update logic in the CSR write process and should now
correctly handle the update when entering debug mode
(4.9.1 Debug Control and Status of the debug specification).
* bump to the latest version of dromajo
* Summary: dromajo DPI change
This change:
* Ariane doesn't commit ebreaks and ecalls so some workaround
was encorporated
* Proper exit(0) on cosim pass
* Summary: support for running binaries with dromajo
This change adds the ability to run the following command:
`make run_dromajo BIN=\path\to\riscv\bin`
It automates the dromajo's checkpoint creation and runs the binary
on Ariane with dromajo cosimulation.
For this to work Ariane must be build with DROMAJO=1.
* changing dromajo recipe name to be consistent with existing names
* adding instructions on how to run cosim with dromajo
* Bump to release 0.6.2
* added license headers
* added more details about dromajo
