[RFC PATCH v4] target/ppc: Convert cache instructions to decodetree
Nikhil Kumar Singh <[email protected]>
| Newsgroups | org.nongnu.qemu-devel |
|---|---|
| Message-ID | <[email protected]> |
Convert cache management instructions to decodetree using custom
X-form layouts (@X_ea, @X_l, @X_th) and dedicated translation functions.
This ensures reserved bits are accurately represented and ignored by
the decoder (using '-' in the patterns), rather than being erroneously
parsed into instruction fields.
Legacy GEN_HANDLER-based implementations are removed.
The implementation preserves legacy semantics, including:
- MMU-visible accesses for instructions treated as loads
(e.g. dcbt, dcbtst, dcbtep, dcbtstep)
- Supervisor and BookE-specific constraints
- Effective address computation via do_ea_calc()
Instructions that were defined as no-ops in the legacy implementation
remain no-ops here.
Note on intentional behavior changes:
- dcbf now validates the L field against the Power ISA v3.1 set of
legal values (0, 1, 3, 4, 6).
- Reserved bits that were previously encoded as part of the opcode
mask (and trapped if set) are now properly decoded as "don't care"
('-' in the pattern).
Testing:
- Verified TCG equivalence for all cache operations

[cr: linux user build, flag check, helper function fixes]
---
v3 -> v4:
- Replaced 'ign' format fields with '-' in instruction patterns
to correctly follow the QEMU decodetree specification.
- Fixed trans_DCBSTEP() incorrectly inheriting REQUIRE_SV() by
separating it from trans_DCBFEP().
- Moved trans_DCBI() CACHE flag check outside of CONFIG_USER_ONLY
to prevent incorrect privilege exceptions in user-mode.
v2 -> v3:
- Addressed feedback from Chinmay regarding reserved bits.
- Defined custom formats (@X_ea, @X_l, @X_th) in insn32.decode to
explicitly capture and ignore reserved bits, preventing them from
being mapped to the 'rt' field.
- Removed manual 'rt != 0' reserved bit checks from translation
functions.
v1 -> v2:
- Added explicit validation for the 'L' field in dcbf to comply
with PowerISA v3.1, properly raising an exception for Undefined
Behavior (UB) values.
