[PATCH v2 0/2] riscv: add rv32i,rv32e and rv64e CPUs

Posted by Daniel Henrique Barboza 10 months, 3 weeks ago

Hi,

This is the second version of a buried patch series:

"[PATCH for-9.0 0/6] riscv: rv32i,rv32e,rv64i and rv64e CPUs"

This version shrank to 2 patches since most of the prep work was already
done by the RVA22 profile implementation, which is now queued in
riscv-to-apply.next.

The motivation is the same as in v1 - give users a cleaner way of using
a customized CPU, from scratch, without the need to disable default
extensions.

Patches based on Alistair's riscv-to-apply.next.

Changes from v1:
- patches 1 to 4 from v1: dropped
- patches 5 and 6 from v1: merged into patch 2
- patch 1 (new):
  - add a new common cpu_init() for all bare CPUs
- v1 link: https://lore.kernel.org/qemu-riscv/20231113213904.185320-1-dbarboza@ventanamicro.com/


Daniel Henrique Barboza (2):
  target/riscv/cpu.c: add riscv_bare_cpu_init()
  target/riscv: add rv32i, rv32e and rv64e CPUs
