Subject: [PATCH v2 00/40] hexagon system emulation v2, part 1/3
Date: Mon,  1 Sep 2025 20:46:35 -0700	[thread overview]
Message-ID: <20250902034715.1947718-1-brian.cain@oss.qualcomm.com> (raw)

Several review issues have been addressed and the series is now rebased.
We are now modeling the global system register state as its own object, and
will likely want to follow up in v3 with a similar change for the global
TLB state.

Issues not yet addressed by v2 (will work on this for v3):
* "Add TCG values for sreg, greg" - combined patch
* "Add imported macro, attr defs for sysemu" - excess attributes
* "Add new macro definitions for sysemu" - READ,WRITE_SREG.  Are they needed?
* "Add sysemu TCG overrides" - arch_get_system_reg() as static inline
* "Add gdb support for sys regs" - checks / mutability of regs via gdbstub TBD
* "Add initial MMU model" - hex_dump_mmu_entry, cpu_index
