[PATCH 0/4] Fix tb flags use

Posted by LIU Zhiwei 1 year, 1 month ago

We have found two places that misuse the fields from env.
The patch set fixes two of them. The first is virt_enabled. And another is vstart.

And for easy moving the tb flag fields, I also make the FS and VS in tb flags
positions changable.

LIU Zhiwei (4):
  target/riscv: Extract virt enabled state from tb flags
  target/riscv: Add a general status enum for extensions
  target/riscv: Encode the FS and VS on a normal way for tb flags
  target/riscv: Add a tb flags field for vstart
