hstateen0h is the RV32 high half of hypervisor state-enable CSR.
RV32 hstateen0[63], controlling VM access to custom state.
C (bit 31) — RV32 hstateen0[63], controlling VM access to custom state.
the corresponding custom state is not accessible; related accesses trap under state-enable rules.
Allows access to the corresponding custom state when other access rules also permit it.
RV32 hstateen0[60], controlling VM access to VS indirect CSR alias state.
CSRIND (bit 28) — RV32 hstateen0[60], controlling VM access to VS indirect CSR alias state.
VS indirect CSR alias state is not accessible; related accesses trap under state-enable rules.
Allows access to VS indirect CSR alias state when other access rules also permit it.
RV32 hstateen0[59], controlling VM access to AIA state not covered by CSRIND or IMSIC.
AIA (bit 27) — RV32 hstateen0[59], controlling VM access to AIA state not covered by CSRIND or IMSIC.
the AIA state controlled by this bit is not accessible; related accesses trap under state-enable rules.
Allows access to the AIA state controlled by this bit when other access rules also permit it.
RV32 hstateen0[58], controlling VM access to guest IMSIC state.
IMSIC (bit 26) — RV32 hstateen0[58], controlling VM access to guest IMSIC state.
guest IMSIC state is not accessible; related accesses trap under state-enable rules.
Allows access to guest IMSIC state when other access rules also permit it.
RV32 hstateen0[57], controlling VM access to context state.
CONTEXT (bit 25) — RV32 hstateen0[57], controlling VM access to context state.
context state such as scontext is not accessible; related accesses trap under state-enable rules.
Allows access to context state such as scontext when other access rules also permit it.
RV32 hstateen0[56], a high-half state-enable bit related to Privileged 1.13 state; confirm portable Hypervisor-side meaning against the current official extension and implementation.
P1P13 (bit 24) — RV32 hstateen0[56], a high-half state-enable bit related to Privileged 1.13 state; confirm portable Hypervisor-side meaning against the current official extension and implementation.
This field is better understood together with surrounding context than as a fixed memorized enumeration.
↗Open Official ManualRV32 hstateen0[55], controlling VM access to environment-configuration state.
ENVCFG (bit 23) — RV32 hstateen0[55], controlling VM access to environment-configuration state.
environment-configuration state such as senvcfg is not accessible; related accesses trap under state-enable rules.
Allows access to environment-configuration state such as senvcfg when other access rules also permit it.
RV32 hstateen0[54:32] bits not listed on this page do not receive portable 0/1 meanings; handle them according to the current official extension, reserved, WPRI, or WARL rules.
RESERVED_OR_EXTENSION_DEFINED (bits 22:0) — RV32 hstateen0[54:32] bits not listed on this page do not receive portable 0/1 meanings; handle them according to the current official extension, reserved, WPRI, or WARL rules.
This field is better understood together with surrounding context than as a fixed memorized enumeration.
↗Open Official Manualhstateen0h is a hypervisor state-enable CSR. It is HS/M-side hypervisor state, not a VS supervisor CSR copy; guest access is governed by the H extension and relevant state-enable, AIA, Sstc, or Smcsrind rules.
Confirm the current software is in an M/HS context that may access Hypervisor CSRs.
Confirm that the H, AIA, Sstc, Smstateen, Smcsrind, or other defining extension is implemented.
Read or write only official fields; whether guest-related access succeeds or traps is controlled by the corresponding extension rules and state-enable state.
Do not treat hstateen0h as a VS CSR copy. It is an H-level CSR; whether guest/VS access to related functionality traps is defined by the H extension and the relevant optional extension.
They control VM access to AIA, guest IMSIC, and indirect CSR alias state, respectively.
