[PATCH v10 0/5] riscv: Allow user to set the satp mode

From: Alexandre Ghiti
Subject: [PATCH v10 0/5] riscv: Allow user to set the satp mode
Date: Fri, 3 Feb 2023 06:58:07 +0100

This introduces new properties to allow the user to set the satp mode,
see patch 3 for full syntax. In addition, it prevents cpus to boot in a
satp mode they do not support (see patch 4).

base-commit: commit 75cc28648574 ("configure: remove
backwards-compatibility code"

- Fix user mode build by surrounding satp handling with #ifndef
- Fix AB/RB from Frank and Alistair

- Move valid_vm[i] up, Andrew
- Fixed expansion of the bitmap map, Bin
- Rename set_satp_mode_default into set_satp_mode_default_map, Bin
- Remove outer parenthesis and alignment, Bin
- Fix qemu32 build failure, Bin
- Fixed a few typos, Bin
- Add RB from Andrew and Bin

- Remove useless !map check, Andrew
- Add RB from Andrew

- Expand map to contain all valid modes, Andrew
- Fix commit log for patch 3, Andrew
- Remove is_32_bit argument from set_satp_mode_default, Andrew
- Move and fixed comment, Andrew
- Fix satp_mode_map_max in riscv_cpu_satp_mode_finalize which was set
  too early, Alex
- Remove is_32_bit argument from set_satp_mode_max_supported, Andrew
- Use satp_mode directly instead of a string in
  set_satp_mode_max_supported, Andrew
- Swap the patch introducing supported bitmap and the patch that sets
  sv57 in the dt, Andrew
- Add various RB from Andrew and Alistair, thanks

- Remove the valid_vm check in validate_vm and add it to the finalize function
  so that map already contains the constraint, Alex
- Add forgotten mbare to satp_mode_from_str, Alex
- Move satp mode properties handling to riscv_cpu_satp_mode_finalize, Andrew
- Only add satp mode properties corresponding to the cpu, and then remove the
  check against valid_vm_1_10_32/64 in riscv_cpu_satp_mode_finalize,
- Move mmu-type setting to its own patch, Andrew
- patch 5 is new and is a fix, Alex

- Simplify v4 implementation by leveraging valid_vm_1_10_32/64, as
  suggested by Andrew
- Split the v4 patch into 2 patches as suggested by Andrew
- Lot of other minor corrections, from Andrew
- Set the satp mode N by disabling the satp mode N + 1
- Add a helper to set satp mode from a string, as suggested by Frank

- Use custom boolean properties instead of OnOffAuto properties, based
  on ARMVQMap, as suggested by Andrew

- Free sv_name as pointed by Bin
- Replace satp-mode with boolean properties as suggested by Andrew
- Removed RB from Atish as the patch considerably changed

- Use error_setg + return as suggested by Alistair
- Add RB from Atish
- Fixed checkpatch issues missed in v1
- Replaced Ludovic email address with the rivos one

Alexandre Ghiti (5):
  riscv: Pass Object to register_cpu_props instead of DeviceState
  riscv: Change type of valid_vm_1_10_[32|64] to bool
  riscv: Allow user to set the satp mode
  riscv: Introduce satp mode hw capabilities
  riscv: Correctly set the device-tree entry 'mmu-type'
