Well, from the history, you inherited from it: commit 1fa639e5618029e944ac68d27e32a99dcb85a349 Author: James Hogan <jhogan@kernel.org> Date: Sat Dec 21 15:53:06 2019 +0000 MAINTAINERS: Orphan MIPS KVM CPUs I haven't been active for 18 months, and don't have the hardware set up to test KVM for MIPS, so mark it as orphaned and remove myself as maintainer. Hopefully somebody from MIPS can pick this up. commit 134f7f7da12aad99daafbeb2a7ba9dbc6bd40abc Author: Aleksandar Markovic <aleksandar.m.mail@gmail.com> Date: Mon Feb 24 12:50:58 2020 +0100 MAINTAINERS: Reactivate MIPS KVM CPUs Reactivate MIPS KVM maintainership with a modest goal of keeping the support alive, checking common KVM code changes against MIPS functionality, etc. (hence the status "Odd Fixes"), with hope that this component will be fully maintained at some further, but not distant point in future. commit 15d983dee95edff1dc4c0bed71ce02fff877e766 Author: Aleksandar Markovic <aleksandar.qemu.devel@gmail.com> Date: Wed Jul 1 20:25:58 2020 +0200 MAINTAINERS: Adjust MIPS maintainership (Huacai Chen & Jiaxun Yang) Huacai Chen and Jiaxun Yang step in as new energy [1]. commit ca263c0fb9f33cc746e6e3d968b7db80072ecf86 Author: Aleksandar Markovic <aleksandar.qemu.devel@gmail.com> Date: Wed Oct 7 22:37:21 2020 +0200 MAINTAINERS: Remove myself I have been working on project other than QEMU for some time, and would like to devote myself to that project. It is impossible for me to find enough time to perform maintainer's duties with needed meticulousness and patience. QEMU deprecation process is quite slow, if we release mips-softmmu and mipsel-softmmu binaries with KVM support in 5.2, and you can not test them, you will still have to maintain them during 2021... If you don't have neither the hardware nor the time, I suggest you to only release it on 64-bit hosts. Personally I'd even only announce KVM supported on the little-endian binary only, because AFAIK you don't test big-endian KVM neither. Your call as a maintainer, but remember last RC tag is next Tuesday (Nov 24) in *4* days, then we release 5.2: https://wiki.qemu.org/Planning/5.2#Release_Schedule Regards, Phil. ^ permalink raw reply [flat|nested] 5+ messages in thread
