Add --dm-no-abstractauto flag to disable support for the optional abstractauto
register. When disabled, writes to the register are ignored and the internal state
is kept at 0.
Currently, neither riscv-openocd nor openocd support batch reads or writes for debug modules
that don’t implement abstractauto, as both assume every debug module provides
abstractauto support. However, work is underway to remove this dependency.
This commit adds support for configuring the number of data registers available
in the debug module. Previously, the debug module had a fixed datasize of 2,
but now users can specify the number of data registers using the --dm-datacount
option when running spike.
The changes include:
- Adding a datacount parameter to debug_module_config_t
- Making dmdata a std::vector instead of a fixed array
- Validating that datacount is between 1 and 12
- Updating the debug module to use the configured datacount
- Adding command-line option to set datacount
- Updating documentation in help output

Previously cache block size had to be initialized via special
set_chache_blocksz setter function and was uninitialized if you didn't
call it. In this commit I move initialization of the block size to the
mmu_t's constructor. The configuration of this member goes through cfg_t
struct.
Adds an optional --instructions=N CLI argument which will stop the simulation after N instructions.
This is useful for benchmarking and profiling and sometimes debugging.
As proposed in #1652, we made the following changes to MMIO device (factory)
plugin API, to mitigate current limitations and facilitate factory reuse.
- removed `sargs` from `device_factory_t`, and introduced a new type alias
`device_factory_sargs_t` to capture `<device_factory_t *, sargs>` pairs,
this is used to instantiate sim_t instances;
- changed the signature of `device_factory_t::generate_fdt` and
`device_factory_t::parse_from_fdt` to take on an extra `sargs` argument,
for instantiating devices with per-device arguments;
- made `device_factory_t` const and potentially resuable across multiple
`sim_t` instances.
PMP Granularity is made available as a command line option. The default
value is 4 Bytes. The value can be changed by passing the option
--pmp-granularity=<value> to spike.

This change allows to create custom implementations of `abstract_mem_t`
and inject them when constructing `sim_t`. The current `mem_t`
implementation remains unchanged.
Fixes#1408.
The --extension feature requires that all symbols in extension.o
be available when the libraries are dynamically loaded by dlopen.
Prepending extension.o to the linker command adds the otherwise
omitted symbols to spike's dynamic symbol table.
Plugins should now implement and register a device_factory_t to
configure how that device should be parsed from a FDT, and an optional
default DTS string.
This drops support for command-line flag-based device configuration
Commit 191634d285 changed the default kernel boot args from
"console=hvc0 earlycon=sbi" to "console=ttyS0 earlycon", but didn't
updated the spike usage help() function.
This commit introduces a new macro DEFAULT_KERNEL_BOOTARGS in order to
have a single definition. This macro is used everywhere in dts.cc and
spike.cc help() function.

The addition of Svadu support and removal of --mmu-dirty
command line flag results in the dirty_enabled configuration state
no longer being used. Remove the remnants of this state.
This commit simplifies the codebase by factoring out memory merging and
intersection checking routines into separate functions. This allows us
to check for corner cases more easily.
