After updating the util/gen_arm_fs_files.py <https://gem5.googlesource.com/public/gem5/+/master/util/gen_arm_fs_files.py> script to use the 4.14 kernel below, I updated the Dockerfile that generates the needed binaries for arm FS simulations here: https://github.com/metempsy/gem5_arm_fullsystem_files_generator I also created a release with up-to-date generated binaries that can be found here: https://github.com/metempsy/gem5_arm_fullsystem_files_generator/releases/download/20180409/aarch-system-20180409.tar.xz Feel free to copy it to http://www.gem5.org/dist/current/arm/ Thanks, Pau <http://metempsy.com/CLA-MAIL-ENG.pdf> Legal notice and data protection / <http://metempsy.com/CLA-MAIL-CAT.pdf> Avís legal i protecció de dades -----Original Message----- From: Andreas Sandberg <andreas.sandb...@arm.com> Sent: Wednesday, March 7, 2018 11:26 To: gem5 Developer List <gem5-...@gem5.org>; gem5 users mailing list <firstname.lastname@example.org> Subject: [gem5-dev] Linux 4.14 and 4.15 with gem5 patches now available for Arm Hi Everyone, I'm happy to announce that we have just completed testing of the gem5-specific patches for Linux 4.14 and 4.15. The new kernel sources can be downloaded from the gem5/v4.14  and gem5/v4.15 branches in the arm/linux  project on Gerrit. Most users should prefer the 4.14 kernel as this is the latest LTS release of Linux. See the wiki  for build instructions. The kernels comes with default configurations for Armv7 and Armv8 and has the same set of gem5-specific patches as the older 4.x kernels. These patches add support for: * gem5's GICv2 extensions. This enables support for up to 255 CPUs if the gem5 extensions are enabled in the GIC (set gem5_extensions to True in your configuration script). * A virtual DRM connector. This makes it possible to use gem5's display models without a proper HDMI encoder model. * The custom FBIOGET_DMABUF IOCTL. This change is useful to avoid a CPU-side memcpy between the GPU's render buffer and the framebuffer for Android setups that using NoMali. * gem5's DVFS controller. * General gem5 instrumentation. Additionally, the upstream 4.15 kernel includes support for the Arm Scalable Vector Extensions (SVE) that can be used with the beta implementation of SVE for gem5 . Known issues: * Recent Linux kernels don't expose the task struct in thread_info. This affects gem5's instrumentation. Some of the Streamline support in gem5 likely needs to be updated to support new kernels. If you need to post any new kernel changes, please make sure to post them to the gem5/v4.14 branch on gerrit.
