Progress (for a week-and-a-half) * UM-2 [QEMU upstream maintainership] + Lots of freeze-related work (softfreeze was last week and we tagged rc0 this week) + Code review of other peoples's stuff to go into the release + Assembling arm pullreqs + Investigating an intermittent failure in one of our test cases on s390 host, which seems like it may be a bug in the s390 h/w-accelerated zlib * QEMU-420 [GICv4 emulation] + Still debugging... -- PMM

Interest in reproducing gcc-linaro-4.9-2016.02 arm-linux-gnueabihf target under darwin and linux aarch64 host

by jhgorse＠gmail.com

Hello, I see this release gcc-linaro-4.9-2016.02 for 86_64_arm-linux-gnueabihf: https://releases.linaro.org/components/toolchain/binaries/4.9-2016.02/arm-l… and would like to reproduce the toolchain for aarch64 hosts. I see that it was built with ABE, though I have generally been unsuccessful in getting ABE to work on aarch64 for this. I was looking for some build or ci breadcrumbs or documentation. What can you recommend? The motivation here is to support legacy development/testing from modern aarch64 hardware. Cheers, Joe Gorse

[Activity] Week #10

by Thiago Jung Bauermann

Hello, # GDB support for ARMv9 Scalable Matrix Extension (SME) - Synced with Luis Machado to learn what the current status is. Read discussions in the linux-arm-kernel mailing list which he pointed to. - Read Arm architecture documentation about Neon, SVE, SVE2 and SME to familiarise myself with these features. - Basic setup / onboarding - Joined some internal and external mailing lists, IRC and Slack channels. - Read some company policy documents. - Researched models and got a quote for a work laptop. - Set up aarch64 cross-compilation environment on my laptop. - Set up emulated aarch64 machine with Fedora on my laptop. - Attempted setting up emulated aarch64 machine with Ubuntu on my laptop, but ran into problems with the Ubuntu Server installer. -- Thiago

[ACTIVITY] report week ending 4 Mar

by Peter Maydell

Progress * UM-2 [QEMU upstream maintainership] + Looked at and sent patches to fix a minor decode error for Neon VLD1/VST1 that RTH found + softfreeze is next Tuesday -- sent out last big Arm pullreq before freeze, though there will probably need to be another smaller one + code review, respinning previously sent patches, looking at bug reports, all to get things in before freeze * QEMU-420 [GICv4 emulation] + All the GICv4.0 stuff is now code-complete, but testing and loose ends (like plumbing it into the virt board) will take a while still. -- PMM

[weekly][linaro] report week ending 25 Feb

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] + Respins of a few patchsets that needed v2 + Looked at a few bugs since softfreeze for 7.0 is near + Amazingly my to-review queue is now almost empty * QEMU-420 [GICv4 emulation] + Implemented more of the redistributor code -- the last missing big piece is its handling of VMOVI, though there are also probably some loose ends to tidy up + Note that this isn't going to be in time for 7.0, so will likely go on the back-burner a bit in favour of release-critical items thanks -- PMM
