[ACTIVITY] report week ending 8 Feb
Progress: * VIRT-65 [QEMU upstream maintainership] + reviewed RTH's patchsets for BTI and MemTag support * VIRT-268 [QEMU support for dual-core Cortex-M Musca board] + Implemented a first pass at a Musca board model, which has the PPC and MPC infrastructure, plus RAM, and ROM for the flash; need to add at least the UARTs and do some testing * misc + sorting out travel arrangements, visa, etc for Connect + kicked off a discussion on whether there are aspects of QEMU's role as the userspace component of a KVM VM that Linaro should be putting more effort/attention into thanks -- PMM ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] report week ending 8 Feb
Fosdem: - Presented on LLD performance at LLVM devroom https://fosdem.org/2019/schedule/track/llvm/ - Other interesting presentations from the devroom include: -- Compiling the Linux kernel with LLVM tools -- Lessons in TableGen LLVM-523 LLD should synthesise .cantunwind .ARM.exidx sections for sections without them - Implementation and regression tests done. Will do a bit more testing and post upstream on Monday. LLVM-521 Taking the address of an ifunc in LLD - Spent some time reviewing upstream patch that should fix the remaining LLD ifunc address equivalence problems for all Targets. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain

Upstream Work ([VIRT-109])
==
- need to finish the re-work of [system test and misc arch] tests
:todo
- will be useful for test cases for plugins
- also more test cases queued up for system tests
- debugged an occasional failure in pauth-1 test case
- expected given PAuth architecture, test needs tightening up
- posted {PATCH v1 0/4} HWCAP_CPUID registers for aarch64 Message-Id:
<20190128173940.25813-1-alex.ben...@linaro.org>
- posted {PATCH v2 0/6} HWCAP_CPUID registers for aarch64 Message-Id:
<20190205190224.2198-1-alex.ben...@linaro.org>
- posted {PATCH v2 00/16} current testing/next queue (with build
fixes) Message-Id: <20190207183744.5054-1-alex.ben...@linaro.org>
- this fixes regression of check-tcg but also
- discovered the Debian Buster's QEMU arm64 packaging is broken
- spent time trying to able to join #debian's IRC channels (aws
hosts banned!)
- tried to revive the cross-tools packaging I'd started with Wookey
