Subject: [PATCH v8 00/15] Introduce the microvm machine type
Date: Thu, 10 Oct 2019 16:31:10 +0200 [thread overview]
Message-ID: <20191010143125.67246-1-slp@redhat.com> (raw)
Microvm is a machine type inspired by Firecracker and constructed
after the its machine model.
It's a minimalist machine type without PCI nor ACPI support, designed
for short-lived guests. Microvm also establishes a baseline for
benchmarking and optimizing both QEMU and guest operating systems,
since it is optimized for both boot time and footprint.

Changelog
v8:
- Split "[PATCH v7 03/12] hw/i386/pc: fix code style issues on
functions that will be moved out" into four different patches
(Philippe Mathieu-Daudé)
v7:
- Fix code style issues on already present code touched by this patch
series (Michael S. Tsirkin, Philippe Mathieu-Daudé)
- Add new files to MAINTAINERS (Michael S. Tsirkin, Philippe
Mathieu-Daudé)
- Allow starting a microvm machine without a kernel image, fixing
"qom-test" (Michael S. Tsirkin)
- Change "bios-microvm.bin" mode to 0644 (Stefano Garzarella)
- Remove unneeded "hw/i386/pc.h" include from x86.c (Stefano
Garzarella)
v6:
- Some style fixes (Philippe Mathieu-Daudé)
- Fix a documentation bug stating that LAPIC was in userspace (Paolo
Bonzini)
- Update Xen HVM code after X86MachineState introduction (Philippe
Mathieu-Daudé)
- Rename header guard from QEMU_VIRTIO_MMIO_H to HW_VIRTIO_MMIO_H
(Philippe Mathieu-Daudé)
v5:
- Drop unneeded "[PATCH v4 2/8] hw/i386: Factorize e820 related
functions" (Philippe Mathieu-Daudé)
- Drop unneeded "[PATCH v4 1/8] hw/i386: Factorize PVH related
functions" (Stefano Garzarella)
- Split X86MachineState introduction into smaller patches (Philippe
Mathieu-Daudé)
- Change option-roms to x-option-roms and kernel-cmdline to
auto-kernel-cmdline (Paolo Bonzini)
- Make i8259 PIT and i8254 PIC optional (Paolo Bonzini)
- Some fixes to the documentation (Paolo Bonzini)
- Switch documentation format from txt to rst (Peter Maydell)
- Move NMI interface to X86_MACHINE (Philippe Mathieu-Daudé, Paolo
Bonzini)
v4:
- This is a complete rewrite of the whole patchset, with a focus on
reusing as much existing code as possible to ease the maintenance burden
and making the machine type as compatible as possible by default. As
a result, the number of lines dedicated specifically to microvm is
383 (code lines measured by "cloc") and, with the default
configuration, it's now able to boot both PVH ELF images and
bzImages with either SeaBIOS or qboot.
v3:
- Add initrd support (thanks Stefano).
v2:
- Drop "[PATCH 1/4] hw/i386: Factorize CPU routine".
- Simplify machine definition (thanks Eduardo).
- Remove use of unneeded NUMA-related callbacks (thanks Eduardo).
- Add a patch to factorize PVH-related functions.
- Replace use of Linux's Zero Page with PVH (thanks Maran and Paolo).
