[PATCH 00/14] hexagon: add semihosting support

Posted by Matheus Tavares Bernardino 1 week, 5 days ago

This series adds semihosting support to hexagon system emulation,
together with functional tests for the added operations.

The Hexagon semihosting spec can be found at:
https://docs.qualcomm.com/doc/80-N2040-101_102648/topic/semihosting-specification.html

Brian Cain (4):
  semihosting: add APIs for chardev-aware guest fd routing
  target/hexagon: Add an errno mapping
  python/machine: support routing semihosting output to the test console
  tests/functional: Add hexagon semihosting systests

Matheus Tavares Bernardino (10):
  target/hexagon: fix get_phys_addr_debug with in-page offset
  target/hexagon: fix PC advancement for non-COF TB terminators
  target/hexagon: add aux functions for guest mem load/store
  hexagon: cpu_helper: add reg reading/writing helpers
  semihosting: add callback to set error
  target/hexagon: add semihosting support
  semihosting: add ftruncate helper (to be used for hexagon)
  target/hexagon: add main arch-specific semihosting operations
  target/hexagon: add COREDUMP semihosting operation
  target/hexagon: add OPEN/READ/CLOSE_DIR semihosting operations

see some build failures on windows and macos.
(feel free to ignore other one, seems to be a network outage issue).
Also, a few checkpatch style issues.

Please also update docs/system/target-hexagon.rst to remove 
"Semihosting is not yet implemented in QEMU hexagon" and add a link to 
the spec.
