[Qemu-devel] [PULL v2 00/11] target/xtensa linux-user support

[Max Filippov]

Hi Peter,

please pull the following series that adds linux-user support for
target/xtensa.
There's a trivial merge conflict with linux-user pull request from
Laurent Vivier.

Changes since v1 pull request:
- fix vaddr print format from %lx to %VADDR_PRIx

Changes since v6 patch series:
- rebase to the current master.

The following changes since commit 026aaf47c02b79036feb830206cfebb2a726510d:

  Merge remote-tracking branch 'remotes/ehabkost/tags/python-next-pull-request' into staging (2018-03-13 16:26:44 +0000)

are available in the git repository at:

  git://github.com/OSLL/qemu-xtensa.git tags/20180316-xtensa

  MAINTAINERS: fix W: address for xtensa (2018-03-16 09:40:35 -0700)

----------------------------------------------------------------
target/xtensa linux-user support.

- small cleanup for xtensa registers dumping (-d cpu);
- add support for debugging linux-user process with xtensa-linux-gdb
  (as opposed to xtensa-elf-gdb), which can only access unprivileged
  registers;
- enable MTTCG for target/xtensa;
- cleanup in linux-user/mmap area making sure that it works correctly
  with limited 30-bit-wide user address space;
- import xtensa-specific definitions from the linux kernel,
  conditionalize user-only/softmmu-only code and add handlers for
  signals, exceptions, process/thread creation and core registers dumping.

----------------------------------------------------------------
Max Filippov (11):
      target/xtensa: dump correct physical registers
      target/xtensa: mark register windows in the dump
      target/xtensa: use correct number of registers in gdbstub
      target/xtensa: support MTTCG
      linux-user: fix mmap/munmap/mprotect/mremap/shmat
      linux-user: fix assertion in shmdt
      linux-user: fix target_mprotect/target_munmap error return values
      linux-user: drop unused target_msync function
      target/xtensa: add linux-user support
      qemu-binfmt-conf.sh: add qemu-xtensa
