Any plan to implement coredump_dump_threads to RISCV processor (PR #74906)

[kwangbaeklee99]

Hi Folks,

I have a couple of questions w.r.t. a new feature(COREDUMP_THREADS).

Q1. Is there any plan to add the feature, "Better support for threads in core dumps",
(#74195) to RISCV architecture?

Q2. It would be perfect if there is a way of limiting the coredumping stack size to
MIN(thread's current stack size, CONFIG_COREDUMP_THREADS_STACK_SIZE) for all threads while coredumping threads.
I mean, in an embedded environment, we don't have enough volatile or non-volatile memory,
for example, the memory allocated for coredump on a chip is only 10 KB and two threads whose stack size is 10 KB each are
running on the board. (Assuming the 4-bit nibble representation of coredump data is not considered here.)
Like the situation above, for instance if we set CONFIG_COREDUMP_THREADS_STACK_SIZE=4096, we could get the stack of
two threads after an exception.

Kind regards,

Kevin
