[Qemu-devel] [RFC PATCH 00/15] Be able to compile out not needed options

[quintela]

From: Juan Quintela <address@hidden>

Hi

this series of patches:
a- move object files only used by one target to that target Makefile.target
b- add flags to disable parts: --disable-{bluez,usb,vwmare,virtio,scsi}
   defaults is leave it enabled.  You need to add the --disable-* flag to get 
any change
c- disable the use of --smb <dir>

What is the intent:  we want to be able to not compile-in things that we are not
interested in (they are experimental/not needed for our target/...).

Is this the right approach?  Should I do something different?

For the next series, I am also interested on enable/disabling bits of a 
subsysem:
being able to support usb-hid but not usb-{host,net,msnd}.  I already have 
patches
to disable that, just waiting to hear what is the preffered way to get
that functionality.

Known problems:
- qemu-*.hx files don't run over cpp and then we are not able to remove from
  the help page the options that we don't support.
- drive_hot_add without scsi support do nothing.

Any comments?

Later, Juan.

  Only compile-in selected audio drivers
  Make --disable-bluez to really remove bluetooth support
  rename usb variable to usb host
  protect with CONFIG_BRLAPI
  Make --disable-usb to really remove usb support
  Add --disable-smb to remove smb directories support
  add option to remove scsi support
  add option to disable wmware devices
  ssi bus is only used on the arm platform
  move i2c devices only used in arm devices to arm target
  sd flash is only used in arm devices
  move m48t59 and ecc driver to ppc and sparc, that are the targets
    that use it
  nand and ecc are only used on arm and cris argets
