[Qemu-devel] [PATCH v3 00/30] Compile only devices that are used


From: Juan Quintela
Subject: [Qemu-devel] [PATCH v3 00/30] Compile only devices that are used
Date: Thu, 27 Aug 2009 21:17:35 +0200

The new config file version!!!!!

v3:
- Now we have a config file by target!!!
- We have configure tool to choose what drivers to compile
      vi <target>/config-devices.mak
- We have another nice tool to check if a config file is valid
      make: if it compiles, it is good, otherwise go to previous step
- Renamed config.h/config.mak to config-target.h and config-target.{h,mak}
      now config.h is not generated, and we can put more stuff there
- I did a go at trying to create config-devices.h, but it is _interesting_
  as we have different names, and have to put one of the files.
  That is the reason why I did the automatic generation of *.h files from
  *.mak files.
- I switched previus patches to this new series.

ToDo:
- there is still a bug when compiling with make -j<n>, sometimes it don't
  generate config-host.h.  Still haven't been able to catch why. Normally
  it works, that is the reason why it is not esay to find what is wrong.
- Pass more stuff to that configuration files.

Comments?

v2:
- ptimer is also used in sparc64 (Blue Swirl)
- generate and compile gdbstub-xml only when needed.

v1:
This series disable complilation of devices that are not used in
any of the selected targets.  Patch series remove all the devices that are
not used for x86_64/i386-softmmu alone.  If you also compiles the softmmu
targets that need them, they are compiled back in.

I sent similar patches to this series a couple of months ago.  The big
different (for those with good memory) is that now I don't move devices
from Makefile.hw and Makefile to Makefile.target.  I just enable/disable
them with CONFIG_FOO and normal building system.

I didn't do it for other platform because I don't have an easy way to test
that I haven't broke anything.  Anyone that uses other platform can do the
same simplification there.


Juan Quintela (30):
  Don't include config-host.mak from inside config.mak
  Move generation of config-host.h to Makefile from configure
  Remove useless check for config-host.mak
  Rename config.{h,mak} config-target.{h,mak}
  Move generation of config-target.h to Makefile from configure
  Add new config-devices.mak for each target
  Generate gdbstub-xml.c only when needed
  Only compile usb_ohci when one target uses it
  Only compile isa_mmio when one target uses it
  Only compile qdev_addr when one target uses it
  Only compile nand when one target uses it
  Only compile ecc when one target uses it
  Only compile esp when one target uses it
  Only compile escc when one target uses it
  Only compile m48t59 when one target uses it
  Only compile ptimer when one target uses it
  Only compile sd when one target uses it
  Only compile max7310 when one target uses it
  Only compile wm8750 when one target uses it
  Only compile twl92230  when one target uses it
  Only compile tsc2005  when one target uses it
  Only compile lm832x  when one target uses it
  Only compile tmp105  when one target uses it
  Only compile stellaris_input when one target uses it
  Only compile sd0303 when one target uses it
  Only compile sd0323 when one target uses it
  Only compile ads7846 when one target uses it
  Only compile max111x when one target uses it
  Only compile ssi-sd when one target uses it
  Only compile ssi when one target uses it
