[Qemu-devel] [PATCH v3 0/5] sdl: Let it be optional (in particular, on OpenBSD)

[Qemu-devel] [PATCH v3 0/5] sdl: Let it be optional (in particular, on OpenBSD)

[Philippe Mathieu-Daudé]

since v2:
- move LM32 specific hardware out of common-obj to bypass make rules limitations
- use "WARNING" string in configure

v1 was too simple to work, so here we go again.
I hit a problem with the Milkymist TMU device when disabling SDL,
so I fixed it and added another patch in this series which clean
a bit the device, but is not required for this series.
The important patches are 1-3, and eventually 1-2 could be squashed
altogether, although the changes are slighly different.

Regards,

Phil.

[Qemu-devel] [PATCH v3 1/5] hw/lm32: Move LM32 specific hardware out of common-obj list

[Philippe Mathieu-Daudé]

The LM32 specific hardware is only used by the LM32 target,
it is pointless to compile those objects in other targets.

I think the idea was to only move the critical object files from
common-obj to obj (i.e. tmu2 only, or the two files in hw/display/).

[Qemu-devel] [PATCH v3 2/5] configure: LM32 Milkymist Texture Mapping Unit (tmu2) also depends of X11

[Philippe Mathieu-Daudé]

Commit 5f9b1e35060b8 remove the dependency between OpenGL and X11.
However the milkymist-tmu2 device do require X11.
When using SDL, the configure script sets need_x11=yes, so the X11
flags are populated to the makefiles.
When building without SDL, X11 is not pulled and populated, leading
to a link failure:

    LINK    lm32-softmmu/qemu-system-lm32

  collect2: error: ld returned 1 exit status
  gmake[1]: *** [Makefile:199: qemu-system-lm32] Error 1

Enforce the X11 dependency when the LM32 target is built.
This will allow us to build QEMU without SDL.

[Qemu-devel] [PATCH v3 4/5] configure: Let SDL support be optional on OpenBSD

[Philippe Mathieu-Daudé]

Currently if we try to build QEMU on OpenBSD with SDL disabled, we get:

  $ ./configure --cc=x86_64-unknown-openbsd6.1-gcc-4.9.4 --python=python2.7 --disable-sdl

  ERROR: sdl not found or disabled, can not use sdl audio driver

Since SDL is not a requirement for OpenBSD, let it be optional.
If it is not found, or the user explicitly disable it, remove it
from the audio_drv_list.
If no audio backends are available, QEMU will fall back to the
null driver.
Instead of displaying nothing when audio_drv_list ends up empty,
display an informative "none".

This does not change the default behavior:

  $ ./configure --cc=x86_64-unknown-openbsd6.1-gcc-4.9.4 --python=python2.7
  SDL support       yes (1.2.15)
  Audio drivers     sdl

  WARNING: Use of SDL 1.2 is deprecated and will be removed in
  WARNING: future releases. Please switch to using SDL 2.0

  GEN     config-host.h
  ...

but allows to build without SDL:

  $ ./configure --cc=x86_64-unknown-openbsd6.1-gcc-4.9.4 --python=python2.7 --disable-sdl
  WARN: sdl not found or disabled, can not use sdl audio driver
  SDL support       no
  Audio drivers     none
  GEN     config-host.h
  ...

Not needed any more.

That puts "none" into the list of audio drivers.  I don't think we
should do that.  If you want prettify the output in case audio_drv_list
is empty, then just fix the output code.

[Qemu-devel] [PATCH v3 5/5] hw/display/milkymist-tmu2: Move inlined code from header to source

[Philippe Mathieu-Daudé]

Move the complexity of milkymist_tmu2_create() into the
source file. Doing so we avoid to include the X11/OpenGL
headers in all LM32 devices, and we also avoid the duplicate
declaration of glx_fbconfig_attr[] (it is already declared
in hw/display/milkymist-tmu2.c).
Since TYPE_MILKYMIST_TMU2 is now accessible, use it.

Hi,

This series failed the docker-mingw@fedora build test. Please find the testing commands and
