QEMU With E2K User Support
968ff692cf
Here's a very, very last minute pull request for qemu-4.1. This fixes two nasty bugs with the XIVE interrupt controller in "dual" mode (where the guest decides which interrupt controller it wants to use). One occurs when resetting the guest while I/O is active, and the other with migration of hotplugged CPUs. The timing here is very unfortunate. Alas, we only spotted these bugs very late, and I was sick last week, delaying analysis and fix even further. This series hasn't had nearly as much testing as I'd really like, but I'd still like to squeeze it into qemu-4.1 if possible, since definitely fixing two bad bugs seems like an acceptable tradeoff for the risk of introducing different bugs. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEdfRlhq5hpmzETofcbDjKyiDZs5IFAl1SXyoACgkQbDjKyiDZ s5K3cA//YA/QK3D3aabaVoqLHPWXuMMQIQaLEwsdzgRYBEzg7r/MOaN85ehVZnhz Fx5sm43eguircfQMgLdOpRuJ/7Mgpl7jgRfJegsQFoW4UqXh0ZVJru0gv8wLsMxe X7eLT2e7uwtnEoy02gqbiHBDiZ51dWSZw6aeSulLFsZsajF9TeBzZ8ENUAeFcLhi lphkh8tzeXfbBivriTuuDI2nfGwtwDsw0JTHNbNxdSTtFxXt1mFH5TUHB8W9CgCC NTqdxWyGlyQKTeIt7eWM8UJ+/BMHMVT/VhqC1syeG8qVdLNIoC5dA2mh02Gqy3cq /KKd12Pd8/bwtYG6PCCXRMudqzeN3AVDSCZ99fEkEyo1lkYlP9o82CTofLHW1Yyz qHFmjoKIgi8iTW9lLYK0ITnVdP8R49sgTx1JwNSPse3V77ljqhCQSu/pI3cCUQY7 5q4W92vhMJpYmGW60iKtp19FPuoPl93DjlO7LMAYs6vmPwcJv5meQ+hq8/cE3K4m D2y/bGH9+K9uM41tcwh50oZcWARHsIxg4rb/Bb/rZZmuhIb56ij7KY+TwVe0w5P6 uFMaRW4AbDHqv+YzaU2jYikPsgD0iJOo8af1PN/FYs8ao4ssRh9ER3d1LOGk8yvr ugycphTQK+Ij7cYwoE6m4Ub0l4CXzYHxpxG+6/yypJBhrq3r6B8= =rtRF -----END PGP SIGNATURE----- Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-4.1-20190813' into staging ppc patch queue 2019-08-13 (last minute qemu-4.1 fixes) Here's a very, very last minute pull request for qemu-4.1.

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
