Subject: [RFC v2 00/13] s390x cleanup
Date: Tue, 20 Apr 2021 12:36:03 +0200
Message-ID: <20210420103616.32731-1-cfontana@suse.de> (raw)

Hi,

this is the next version of a cleanup series for s390x.

v1 -> v2: split more, stubs removal for KVM, kvm/ move, sysemu cpu models

* "hw/s390x: rename tod-qemu.c to tod-tcg.c"
  - new patch (Cornelia)

* "hw/s390x: tod: make explicit checks for accelerators when initializing"
  - now error out and abort() for an unknown accelerator. (Cornelia)

* "target/s390x: remove tcg-stub.c" : new patch split from
  "target/s390x: start moving TCG-only code to tcg/" (Cornelia)

* "target/s390x: use kvm_enabled() to wrap call to kvm_s390_get_hpage_1m"
  - new patch, allows the removal of kvm stubs

* "target/s390x: remove kvm-stub.c"
  - new patch, we do not need stubs, as all calls are wrapped by
    kvm_enabled(), and all prototypes are visible.

* "target/s390x: move kvm files into kvm/"
  - new patch

* "target/s390x: split sysemu part of cpu models"
  - new patch

* "MAINTAINERS: update s390x directories"
  - new patch


Pre-requisite series (not really needed for now, only in further work down the line):

Comments welcome, thanks,
