[Qemu-devel] [PATCH 0/9] target/xtensa: implement options for modern cores

Posted by Max Filippov 9 weeks ago
Hello,

this series implements options used by the modern xtensa cores: memory
protection unit, block prefetch and exclusive access and adds special
register definitions and IRQ types for a few other options not fully
implemented: ECC/parity, scatter/gather and IDMA.

Max Filippov (9):
  target/xtensa: get rid of centralized SR properties
  target/xtensa: make internal MMU functions static
  target/xtensa: define IDMA and gather/scatter IRQ types
  target/xtensa: add parity/ECC option SRs
  target/xtensa: implement MPU option
  target/xtensa: implement DIWBUI.P opcode
  target/xtensa: implement block prefetch option opcodes
  target/xtensa: update list of exception causes
  target/xtensa: implement exclusive access option
