[PATCH v6 0/3] Support RISC-V IOPMP
Posted by Ethan Chen via 9 months, 3 weeks ago 
This series implements IOPMP specification v1.0.0-draft4 rapid-k model and add
IOPMP device to RISC-V virt machine.

Patch 1 add config STREAM make other device can reuse /hw/core/stream.c, IOPMP
implementation will use it. Patch 2 implement IOPMP deivce. Patch 3 add IOPMP
device to RISC-V virt machine.

The IOPMP specification url:
https://github.com/riscv-non-isa/iopmp-spec/blob/main/riscv_iopmp_specification.pdf

Changes for v6:
  - Rebased
  - IOPMP: Fix MDLCK_MD and ENTRYLCK_F did not lock correspond registers
           Fix iopmp_write for ENTRY_ADDRH and ENTRYLCK_L
  - Refine coding style (Daniel Henrique Barboza)

Thanks,
Ethan Chen

Hi Ethan,


Did you send v7 already and I somehow missed it? This is the latest version I
have for this IOPMP work in my inbox.

If this is the latest, do you plan to send a new version? Most of the comments
made in patche 2 are simple code style changes and there's no technical reason to
not get this work merged for this release.


Thanks,

Daniel

Hi Dainel,

Sorry for the delayed response. I've been busy over the past two months.
I plan to submit the next version of the patch within two weeks.

Thanks,
Ethan Chen
