[PATCH v11 0/5] riscv: Allow user to set the satp mode
Posted by Alexandre Ghiti 1 year ago
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 c61d1a066cb6 ("Merge tag 'for-upstream' of
https://gitlab.com/bonzini/qemu into staging")

v11:
- rebase on top of master
- Added RB/AB from Frank and Alistair
- Use VM_1_10_XX directly instead of satp_mode_from_str, from Frank
- Set satp mode max for thead c906 to sv39

v10:
- Fix user mode build by surrounding satp handling with #ifndef
  CONFIG_USER_ONLY, Frank
- Fix AB/RB from Frank and Alistair

v9:
- 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

v8:
- Remove useless !map check, Andrew
- Add RB from Andrew

v7:
- 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

v6:
- 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,
  Andrew/Alistair/Alex
- Move mmu-type setting to its own patch, Andrew
- patch 5 is new and is a fix, Alex

v5:
- 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

v4:
- Use custom boolean properties instead of OnOffAuto properties, based
  on ARMVQMap, as suggested by Andrew

v3:
- 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

v2:
- 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'

I have that, but I still got some merge conflicts.  I've put that here 
<https://github.com/palmer-dabbelt/qemu/tree/set-satp> for now, pending 
Daniel's response below.

Daniel: It looks like the feedback on v10 included dropping the first 
patch
<https://lore.kernel.org/qemu-devel/66d80b94-5941-31f3-995f-e9666a91fbb7@ventanamicro.com/T/#macdb6c5232bd8c082966107d7b44aaaec9b29ad6>.
Sorry if I'm just misunderstanding, but it looks to me like that patch 
is still useful and the v11 doesn't even build without it.

I believe I mentioned that patch 1 was obsolete in the context of version 10, where
I think I also mentioned that a rebase would be good.

Alexandre rebased it and, from what I can see, patch 1 looks good to go.


Thanks,

Daniel

Weird, I have just tried again and it applied cleanly on the
base-commit I mentioned, I tried to cherry-pick a few patches, even
commit d4ea71170432 ("target/riscv: introduce riscv_cpu_cfg()") does
not break the merge.

Anyway, FWIW I checked the patches on the set-satp branch again, and
your merge seems ok.

No, the first commit is a preparatory commit for the series, it is required.
