[Qemu-devel] [RFC PATCH v3 00/43] Support Kconfig in QEMU


From: Yang Zhong
Subject: [Qemu-devel] [RFC PATCH v3 00/43] Support Kconfig in QEMU
Date: Fri, 18 Jan 2019 19:23:27 +0800

This Kconfig implementation is rebased from Paolo's branch
https://github.com/bonzini/qemu/commits/kconfig

I rebased most of patches except non-x86 ARCHs dependency definitions
this time.
https://github.com/yangzhon/qemu/commits/topic/upstream/Kconfig

The current RFC patches only support
(*) x86_64 platform build
    Once design is fixed, we can do other archs.

(*) defconfig
    "randconfig" build has some issues, which are mostly related
    with CONFIG* in Kconfig.host abd configure. In randconfig mode,
    some CONFIG* has different setting value in config-host.mak and
    %/config-device.mak, which make QEMU build failure.

(*) Kconfig in hw/ directory

The current configure and build command are same with previous
commands and if we want to disable or enable some features, like
"tcg", we still need add "--enable/--disable-tcg" in configure
command line. If we want to disable one emulation device, we can
disable this in related Kconfig file in hw/ directory.

The current build command:
(*) ./configure --target-list=x86_64-softmmu
(*) make -j8

Since the Kconfig language replace traditional CONFIG_* in
default-config/%-softmmu.mak, the %-softmmu.mak file only
define embeded boards or machines, like 440fx and Q35 in x86_64
platform. The Kconfig has already defined dependency topology
between different Kconfig files, but there are still some issues

(*) Kconfig for configure(config-host.mak)
    Some CONFIG* in configure  need some logic to generate, those
    are hard to input this CONFIG* in Kconfig.host or Kconfig* file.

(*) Kconfig for %config-target.mak
    The CONFIG* in %/config-target.mak file, this is still related
    with configure.

(*) randconfig support issue.

Before this RFC patches, we have talked Kconfig in another thread
http://lists.nongnu.org/archive/html/qemu-devel/2018-09/msg02827.html

Please give your comments on this RFC thread, many thanks!
