[ACTIVITY] week ending 22 July 2018
[Upstream] Spent several days working with Alex and his docker testing bits. Reproduced the reported ppc32 test failure. Wrote a patch to implement the swapcontext syscall, which has now been merged. Round 3 review of nanoMIPS submission. Fixed a tricky issue wrt call-clobbered vector registers. [VIRT-198 # QEMU: SVE Emulation Support ] Some back and forth with Nils Meyer wrt SVE vs Grid. TODO: Let the SVE vector length be selectable from the command-line. r~ ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
Abstract: My Other Machine is Virtual
Following on from last weeks discussion here is an alternative abstract which instead of looking to the future with where QEMU can go would concentrate on what you can do with QEMU now. What do you think? _ MY OTHER MACHINE IS VIRTUAL Alex Bennée _ YVR18 When working with new architectures there is often a scramble for getting access to hardware. However hardware comes with it's own problems - especially when it's new. It's hard to upgrade, hard to poke around inside and hard to experiment with. This is an area where QEMU can help. Thanks to it cross-architecture emulation and ability to run full-system emulation it provides a platform for experimentation without the potential consequences of turning your new board into a inanimate brick. This talk will start with an overview of QEMU and how various configurations can be setup. We'll then examine various features available that allow us to examine the run time behaviour of code inside QEMU as well as discuss some of its limitations. Finally we'll look at some experiments that would be hard to do with real hardware and what they can tell us about the code we are running. -- Alex Bennée ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
