[Buildroot] [pull request v2] Pull request for branch yem-target-qemu

[Yann E. MORIN]

Hello All!

This series is the last part required to build QEMU for the target.

It depends on the previous series that was just sent:
  - http://lists.busybox.net/pipermail/buildroot/2013-January/066369.html

The philosophy behind this long series is to add a basic, non-configurable
QEMU build (which is already complex as it is), then add features one by
one to ease review.

The latest patch, adding DTC, has been a bit controversial, but no final
solution has been identified (as far as I remember), so I've kept it as-is.

Hopefully, we'll have time to review and definitely ack/nack this series
during the DevDay in Brussels. ;-)


Changes v1 -> v2:
  - rebased ontop latest tree
  - fixed wreckage due to bump from QEMU 1.2.2 -> 1.3.0
  - updated to QEMU 1.3.1
  - added option to install QEMU tools on the target


The following changes since commit 24a0d3a9cf23549854ea6830abc9e04a974e9900:

  package/dtc: add option to install programs (2013-01-29 23:21:12 +0100)

[Buildroot] [PATCH 02/29] package/qemu: build for the target (i386 or x86_64 only)

[Yann E. MORIN]

Untested for other architectures, so only enabled for known-working ones.

We explicitly disable all features that depends on other packages,
for now. Such features will be added one by one in the next patches.
Features that do not rely on external packages are explicitly enabled
to catch the dependencies on toolchain features early.

Dear Yann E. MORIN,

Then please do not use the autotools-package infrastructure for this
package. It doesn't use autoconf, it doesn't automake, it is *NOT*
autotools.

It is not because it happens to work *today* by just overriding the
QEMU_CONFIGURE_CMDS that it will continue to work tomorrow. For
example, look at the out-of-tree stuff I was working on: for autotools
packages, we will assume that out of tree build is supported, and that
it works in a certain way. Wouldn't this break the qemu package, which
pretends to be an autotools package, but in fact is not?

So, I've said this several times already: do not misuse package
infrastructures, even if it happens to "work" today. Do the right
thing, instead: qemu should use the generic-package infrastructure.

Thanks!

Thomas

[Buildroot] [PATCH 03/29] package/qemu: add basic target selection

[Yann E. MORIN]

qemu-1.2.1 requires that at least one target emulation be enabled, so
we use some kconfig-tricks to force at least the systems emulations to
be enabled if user emulation is not selected.

This limitation will be lifted in the upcoming qemu-1.3.x

Humm, the qemu package actually uses version 1.3.1, as per "[PATCH
01/29] package/qemu: bump version to 1.3.1" :-)

You also have the comment related to 1.2.x in the patch itself.

[Buildroot] [PATCH 28/29] package/qemu: enable a static build

[Yann E. MORIN]

Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

---
It can be useful to have a statically-linked QEMU (especially the
linux-user and bsd-user emulators) to avoid run-time issues with
dynamically-loaded libraries.

There is an issue where QEMU could not be able to properly (re)map
libraries in memory due to some overlap between its own memory
mappings and the mappings of the user application being translated
(it's a complex issue, so don't count on me to properly explain it,
I did not understood it completely either... :-/ ).

+configure: fix detection for cURL libs when static linking
+
+Currently, to check for cURL, configure uses either pkg-config (the default),
+or curl-config (as a fallback).
+
+But curl-config and pkg-config do not have the same set of options:
+  - to check for shared libs, both use the option: --libs
+  - to check for static libs:
+    - pkg-config uses: --static --libs
+    - curl-config uses: --static-libs
+
+To add to the complexity, pkg-config is called through the querry_pkg_config
+wrapper, that already passes --static when static linking is required, but
+there is no such wrapper for curl-config, so we miss the occasion to pass
+--static-libs
+
+To fix this:
+  - introduce a new variable QEMU_XXX_CONFIG_LIBS_FLAGS that mirrors the
+    behavior of QEMU_PKG_CONFIG_FLAGS; this variable can be used by all
+    xxx-config scripts (eg. curl-config, but later sdl-config too).
+    Default it to '--libs', which is for shared linking;
+  - properly use either --libs for pkg-config (--static is already takend
+    care of in the wrapper), or $QEMU_XXX_CONFIG_LIBS_FLAGS for
+    curl-config.

+configure: fix detection for SDL libs when static linking
+
+Currently, configure checks for SDL libs with either pkg-config (the
+default), or with sdl-config (as a fallback).
+
+As for cURL (previous patch), sdl-config does not have the same set of
+options as pkg-config:

+  - to check for static libs:

+
+Fix that by using the previously introduced $QEMU_XXX_CONFIG_LIBS_FLAGS
+variable, the way ot was done previously for cURL.
+
+Also, simplify the code-path for checking for SDL libs with a single,
+non-conditional call to $sdlconfig, which is either pkg-config or
+sdl-config, as checked just above.

[Buildroot] [PATCH 29/29] package/qemu: add support for FDT

[Yann E. MORIN]

FDT is the Flat Device Tree, and allows QEMU to pass DTs to the VMs.

[Buildroot] [pull request v3] Pull request for branch yem-target-qemu

[Yann E. MORIN]

Hello All!

This series is the last part required to build QEMU for the target.

It depends on the previous series that was just sent:
  - http://lists.busybox.net/pipermail/buildroot/2013-February/066541.html

The philosophy behind this long series is to add a basic, non-configurable
QEMU build (which is already complex as it is), then add features one by
one to ease review.

The latest patch, adding DTC, has been a bit controversial, but no final
solution has been identified (as far as I remember), so I've kept it as-is.

Hopefully, we'll have time to review and definitely ack/nack this series
during the DevDay in Brussels. ;-)


Changes v2 -> v3:
  - changed to using generic-package (Thomas)
  - fixed comments about QEMU-1.2, we're using 1.3.1 now (Thomas)
  - added ability to install tools on target
  - added ability to install no emulator on target

Changes v1 -> v2:
  - rebased ontop latest tree
  - fixed wreckage due to bump from QEMU 1.2.2 -> 1.3.0
  - updated to QEMU 1.3.1
  - added option to install QEMU tools on the target
