QEMU With E2K User Support
94c01767aa
Here's a set of bugfixes for ppc, aimed at qemu-4.0 during hard freeze. We have one cleanup that's not strictly a bugfix, but will avoid an ugly external interface making it to a released version. We have one change to generic code to tweak the semantics of qemu_getrampagesize() which fixes a bug for ppc. This does have a possible impact on s390x which uses this function for a different purpose. I've discussed with David Hildenbrand and Igor Mammedov, however and we think it won't immediately break anything due to some existing bugs in the s390 usage. David H will be following up with some s390 fixes in that area. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEdfRlhq5hpmzETofcbDjKyiDZs5IFAlydkLUACgkQbDjKyiDZ s5KYWw/+MWHPjYrgq2YqWr5VwRFhjV3gg86sQKCq+k/OhRl1ALmQ8DIDA5IBU/zf EmFPOdE4hvaCbYRLDyBL5ayVR/obu1+J3SHo1gDNAoXnpSIoTN+a2DeL8qfQekQL 0EyPnARHlZZiHVM7YWyKIKUKpsptT5TRuZrUmM4pWXNWhk3qF39XQ0gCnMqdfd5U n8qcKKz9UxlFPkhyw/mGveMV1eJTlw1EQCyvUsfCgoK0LljDUvlZPCOI/O2jupPn mL7CifCm2yPs9ZuEgr/YSNYUCk96gf4hTdN2FiqdZWYbgUQaMDW/HtL6DwR5jI1W IXqnD7qsJxrHzsw9ZWBTjcK1PGaw2UMnuHNemI/T6sZP7UIsU3DmKsVA14GEWVBa zdO9HxQNa+UjKKtpTijqGxga3jya236a2ssgTr871chWs6cPH2db/iHNUM15ri1J wVFmQpAJrLNy5KLGL8Mgs6muH4DVaefKhWdGy3A/l5ThDZp0yAb27sYwVqzHm7P8 L+jbEoWqRgplkVOtx9jCBjiuca5Sdwi2uhZ5Q6bjEwTPcMU90J6NcsN92/QvEuod Tmx/SZs81Pzg8Icq7AMbPbHaVYLy6pDlxIE8KX5wCrhqbWaH2UaxBU2M8mDOdxS5 AihcQA+KUwnBiRRLaANTGnfJ3FZMNak7qwBP6clNKpazsv53f7Q= =sHfP -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-4.0-20190329' into staging ppc patch queue 2019-03-29 Here's a set of bugfixes for ppc, aimed at qemu-4.0 during hard freeze.

QEMU README =========== QEMU is a generic and open source machine & userspace emulator and virtualizer. QEMU is capable of emulating a complete machine in software without any need for hardware virtualization support. By using dynamic translation, it achieves very good performance. QEMU can also integrate with the Xen and KVM hypervisors to provide emulated hardware while allowing the hypervisor to manage the CPU. With hypervisor support, QEMU can achieve near native performance for CPUs. When QEMU emulates CPUs directly it is capable of running operating systems made for one machine (e.g. an ARMv7 board) on a different machine (e.g. an x86_64 PC board). QEMU is also capable of providing userspace API virtualization for Linux and BSD kernel interfaces. This allows binaries compiled against one architecture ABI (e.g. the Linux PPC64 ABI) to be run on a host using a different architecture ABI (e.g. the Linux x86_64 ABI). This does not involve any hardware emulation, simply CPU and syscall emulation. QEMU aims to fit into a variety of use cases. It can be invoked directly by users wishing to have full control over its behaviour and settings. It also aims to facilitate integration into higher level management layers, by providing a stable command line interface and monitor API. It is commonly invoked indirectly via the libvirt library when using open source applications such as oVirt, OpenStack and virt-manager. QEMU as a whole is released under the GNU General Public License, version 2. For full licensing details, consult the LICENSE file. Building ======== QEMU is multi-platform software intended to be buildable on all modern Linux platforms, OS-X, Win32 (via the Mingw64 toolchain) and a variety of other UNIX targets. The simple steps to build QEMU are: mkdir build cd build ../configure make Additional information can also be found online via the QEMU website: https://qemu.org/Hosts/Linux https://qemu.org/Hosts/Mac https://qemu.org/Hosts/W32 Submitting patches ================== The QEMU source code is maintained under the GIT version control system. git clone https://git.qemu.org/git/qemu.git When submitting patches, one common approach is to use 'git format-patch' and/or 'git send-email' to format & send the mail to the qemu-devel@nongnu.org mailing list. All patches submitted must contain a 'Signed-off-by' line from the author. Patches should follow the guidelines set out in the HACKING and CODING_STYLE files. Additional information on submitting patches can be found online via the QEMU website https://qemu.org/Contribute/SubmitAPatch https://qemu.org/Contribute/TrivialPatches The QEMU website is also maintained under source control. git clone https://git.qemu.org/git/qemu-web.git https://www.qemu.org/2017/02/04/the-new-qemu-website-is-up/ A 'git-publish' utility was created to make above process less cumbersome, and is highly recommended for making regular contributions, or even just for sending consecutive patch series revisions. It also requires a working 'git send-email' setup, and by default doesn't automate everything, so you may want to go through the above steps manually for once. For installation instructions, please go to https://github.com/stefanha/git-publish The workflow with 'git-publish' is: $ git checkout master -b my-feature $ # work on new commits, add your 'Signed-off-by' lines to each $ git publish Your patch series will be sent and tagged as my-feature-v1 if you need to refer back to it in the future. Sending v2: $ git checkout my-feature # same topic branch $ # making changes to the commits (using 'git rebase', for example) $ git publish Your patch series will be sent with 'v2' tag in the subject and the git tip will be tagged as my-feature-v2. Bug reporting ============= The QEMU project uses Launchpad as its primary upstream bug tracker. Bugs found when running code built from QEMU git or upstream released sources should be reported via: https://bugs.launchpad.net/qemu/ If using QEMU via an operating system vendor pre-built binary package, it is preferable to report bugs to the vendor's own bug tracker first. If the bug is also known to affect latest upstream code, it can also be reported via launchpad. For additional information on bug reporting consult: https://qemu.org/Contribute/ReportABug Contact ======= The QEMU community can be contacted in a number of ways, with the two main methods being email and IRC - qemu-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/qemu-devel - #qemu on irc.oftc.net Information on additional methods of contacting the community can be found online via the QEMU website: https://qemu.org/Contribute/StartHere -- End
