At present gdbstub reports an incorrect / incomplete CSR list in the
target description XML, for example:
- menvcfg is reported in 'sifive_u' machine
- fcsr is missing in a F/D enabled processor
The issue is caused by:
- priv spec version check is missing when reporting CSRs
- CSR predicate() routine is called without turning on the debugger flag
This series aims to generate a correct and complete CSR list for gdbstub.
Bin Meng (18):
target/riscv: gdbstub: Check priv spec version before reporting CSR
target/riscv: Correct the priority policy of riscv_csrrw_check()
target/riscv: gdbstub: Minor change for better readability
target/riscv: gdbstub: Do not generate CSR XML if Zicsr is disabled
target/riscv: Coding style fixes in csr.c
target/riscv: Use 'bool' type for read_only
target/riscv: Simplify {read,write}_pmpcfg() a little bit
target/riscv: Simplify getting RISCVCPU pointer from env
target/riscv: Avoid reporting odd-numbered pmpcfgX in the CSR XML for
RV64
target/riscv: gdbstub: Turn on debugger mode before calling CSR
predicate()
target/riscv: gdbstub: Drop the vector CSRs in riscv-vector.xml
target/riscv: Allow debugger to access user timer and counter CSRs
target/riscv: Allow debugger to access seed CSR
target/riscv: Allow debugger to access {h,s}stateen CSRs
target/riscv: Allow debugger to access sstc CSRs
target/riscv: Drop priv level check in mseccfg predicate()
target/riscv: Group all predicate() routines together
target/riscv: Move configuration check to envcfg CSRs predicate()
