[Qemu-devel] [ARM SMBIOS RFC PATCH 3/5] smbios: pass ram size as a parameter to build smbios tables

[Qemu-devel] [ARM SMBIOS RFC PATCH 0/5] SMBIOS Support for ARM

SMBIOS tables present userful system hardware info to management applications, such as DMI tools. Even though SMBIOS was originally developed for Intel x86, it has been extended to both Itanium and ARM (32bit & 64bit). More and more ARM server releases, such as RHEL Server for ARM, start to integ

[Qemu-devel] [ARM SMBIOS RFC PATCH 4/5] smbios: move smbios code into a common folder

Thank you for your comments. I'm currently writing a v2 of this patch with what I've learned working on the netlink interface. I will fix it accordingly all your comments. [ Now, I can boot a PPC64 container with systemd on an x86_64 host: https://asciinema.org/a/7sgwvok72m34v7hg08hfspg4s ] Laur
