Progress: * UM-2 [QEMU upstream maintainership] + More of the usual freeze-related work * QEMU-420 [GICv4 emulation] + I think the code is more or less bug-free now; still need to figure out the best way for a board to request a GICv4 (eg do we want a 'revision' property specifying 3, 3.1, 4, 4.1, or just 3 vs 4 with some optional booleans for extra features?) -- PMM

[ACTIVITY] Report for week #11

by Thiago Jung Bauermann

Hello, # [GNU-732] GDB support for ARMv9 Scalable Matrix Extension (SME) * Continued reading patches from Mark Brown's v12 patch set adding SME support to the Linux kernel. Sent a few trivial review comments. * After conversation with Luis, decided to work on gdbserver and remote protocol support for programs which change the SVE vector length during execution (native GDB already supports it). This issue will most likely be relevant for SME as well. Started by studying Luis' proposal from 2020 and background information provided by him. # Basic setup / onboarding * Bought a work laptop. * Set up access to the team's machines. -- Thiago

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

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
