Hi Ana, I don't know anything about the POC myself, but I'm forwarding this so our QEMU folks can answer. Cheers, Diana ---------- Forwarded message --------- From: Ana Pazos <apazos(a)quicinc.com> Date: Fri, 10 Jan 2020 at 19:08 Subject: about QEMU support for SVE2 POC To: diana.picus(a)linaro.org <diana.picus(a)linaro.org> Cc: Ana Pazos <apazos(a)quicinc.com> Hello Diana, We at Qualcomm are trying to find out the POC for QEMU support for SVE2. We have been using QEMU with SVE support, and need to find out when SVE2 support will be added to QEMU. I assume Linaro is involved in this task. Do you know the POC? Thanks for the help! Ana.

== Progress == * BFD Linker: - GNU-629: non-contiguous memory support: sent updated versions with testcases and doc. * GCC: - trying to find a way to add run more validation of -mpure-code on v6m, to support a request to backport to gcc-9 - proposal to implement LLVM's -arm-assume-misaligned-load-store rejected by the community * GCC upstream validation: - reported/checked a few issues * misc: - infra fixes / troubleshooting / reviews - investigating problems with automatic bisection of gcc regressions - fixed a long-standing bug in proot == Next == * Binutils: GNU-629: support non-contiguous memory regions in linker

Morello: - Implemented INPUT_SECTION_FLAGS in LLD for the Morello toolchain, now in review. Took most of spare engineering time this week. Will attempt to upstream once committed in Morello - Fixed pr44451 upstream, it was already fixed on Morello toolchain. LLD: - Made an attempt to fix the LLD linux kernel allyesconfig + cortex-a53 erratum problem. Was not successful as kernel linker script is just about as awkward as possible for this problem. I have a good idea of what to try next. Will aim to fix early next week. - Quite a few upstream reviews, some pending from last year.

[ACTIVITY] report week ending 10 Jan

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] - caught up on the backlog of email that accumulated over the Christmas break - investigated an intermittent failure of a test case on our BSD hosts which had reached a failure rate that was seriously impeding the flow of pull requests. Tracked it down to glib's g_source_ref/unref not being thread-safe unless the GSource is attached to a GMainContext; QEMU gets this right for its own use but a set of mock functions used for a few testcases were not doing so, resulting in occasional races where the GSource would get destroyed while it was still in use. - code review: + Beata's "inject DABT for load/store insns KVM couldn't emulate" patch + a minor cubieboard cleanup patchset + i.MX RNGC device emulation patch - annual review season, some time spent on that thanks -- PMM

Bot failure caused by f72d001e099871fd5943679a8377f2fcc675f860

by Michael Trent

To whom, I’m seeing a failure on this bot: -- Command Output (stderr): -- /home/buildslave/buildslave/clang-cmake-armv7-quick/stage1/bin/llvm-objdump: error: '/home/buildslave/buildslave/clang-cmake-armv7-quick/llvm/llvm/test/tools/llvm-objdump/Inputs/macho-stabs-x86_64': can't find target: : error: unable to get target for 'x86_64---macho', see --version and --triple. This is just a binary file verifier. Is it the case this bot doesn’t have a mach-o disassembler? And if so, is there a way to disable this test on this bot? Thanks! MDT
