+Subject: [PATCH] third_party/threads: Use PTHREAD_MUTEX_RECURSIVE by default
+
+PTHREAD_MUTEX_RECURSIVE_NP was used for compatibility with old glibc.
+Although due to the_GNU_SOURCES define the portable,
+PTHREAD_MUTEX_RECURSIVE will be available for Linuxes since at least
+1998. Simplify things giving us compatibility with musl which
+apparently does not provide the non-portable define.
+
+Inspired by almost identical commit in mesa aead7fe2e2b(c11/threads: Use
+PTHREAD_MUTEX_RECURSIVE by default) by Felix Janda.

+Subject: [PATCH] cmake: forward cflags from *.pc files to waffle cflags
+
+When building mesa egl without x11 and gles2 the headers need a
+MESA_EGL_NO_X11_HEADERS define to avoid including X11 headers.
+
+This define MESA_EGL_NO_X11_HEADERS  is lost while building waffle
+since CGLAGS defined by pc files are not used.
+
+MESA_EGL_NO_X11_HEADERS is defined in CFLAGS from egl.pc.

+	  Waffle is a cross-platform library that allows one to defer
+	  selection of an OpenGL API and of window system until
+	  runtime. For example, on Linux, Waffle enables an application
+	  to select X11/EGL with an OpenGL 3.3 core profile, Wayland
+	  with OpenGL ES2, and other window system / API combinations.
+
+	  Waffle's immediate goal is to enable Piglit [1] to test
+	  multiple OpenGL flavors in a cross-platform way, and to allow
+	  each Piglit test to choose its OpenGL API and window system
+	  at runtime. A future goal is to enable the ability to record
+	  (with another tool such APITrace [2]) an application's OpenGL
+	  calls on one operating system or window system, and then
+	  replay that trace on a different system.
+
+	  For more information, visit to Waffle's website.

[Buildroot] [PATCH v2 3/3] package/piglit: new package

[Romain Naour]

Piglit is an open-source test suite for OpenGL implementations.
It's an python3 script based around several tools like glxinfo,
wflinfo, dmesg.

Even though waffle support can be replaced by freeglut,
using pliglit with waffle is recommended since freeglut
will be replaced by waffle.

Bernd, I'm Cc you since you're probably interested by piglit to
test new mesa3d version.

The dependency comment should be updated accordingly.

Any reviewer ?

[Buildroot] [PATCH v2 2/3] package/waffle: new package

[Thomas Petazzoni]

Hello Romain,

I finally took some time to look at this package again, and I think the
dependencies are not correctly handled.

> +config BR2_PACKAGE_WAFFLE

Due to this dependency, you cannot do a build which has just mesa3d as
a gbm/egl provider + udev, which is a valid configuration supported by
waffle.

I.e, the following defconfig builds waffle properly:

BR2_arm=y
BR2_cortex_a8=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_NONE=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST=y
BR2_PACKAGE_MESA3D_OPENGL_EGL=y
BR2_PACKAGE_WAFFLE=y
# BR2_TARGET_ROOTFS_TAR is not set

> +	depends on BR2_PACKAGE_HAS_LIBGL || BR2_PACKAGE_HAS_LIBEGL
> +	# OpenGL ES (1,2,3) libraries are loaded at runtime when needed
> +	# in addition to LIBGL or LIBEGL.
> +	depends on BR2_PACKAGE_HAS_LIBGLES

This dependency means that you cannot build waffle at all if there's no
GLES support. Therefore a desktop configuration that provides GL will
not allow building waffle. That's not good.

Looking more closely into the Waffle build system, it has four
"backends", each having their own dependencies. At least one "backend"
must be enabled, otherwise Waffle will refuse to build. The "backends"
are:

 - glx, which needs full OpenGL + x11-xcb
 - wayland, which needs wayland-client, wayland-egl and EGL
 - x11-egl, which needs x11-xcb and EGL
 - gbm, which needs gbm, libudev and EGL

So the easiest is perhaps to map this to hidden Config.in options,
maybe something like:

config BR2_PACKAGE_WAFFLE_SUPPORTS_GLX
	bool
	default y if BR2_PACKAGE_HAS_LIBGL && BR2_PACKAGE_XORG7

config BR2_PACKAGE_WAFFLE_SUPPORTS_WAYLAND
	bool
	default y if BR2_PACKAGE_WAYLAND && BR2_PACKAGE_HAS_LIBEGL_WAYLAND

config BR2_PACKAGE_WAFFLE_SUPPORTS_X11_EGL
	bool
	default y if BR2_PACKAGE_HAS_LIBEGL && BR2_PACKAGE_XORG7

config BR2_PACKAGE_WAFFLE_SUPPORTS_GBM
	bool
	# mesa3d is for now the only GBM provider, and it is enabled
	# together with its EGL support
	default y if BR2_PACKAGE_HAS_LIBEGL && BR2_PACKAGE_MESA3D_OPENGL_EGL && BR2_PACKAGE_HAS_UDEV

config BR2_PACKAGE_WAFFLE
	bool "waffle"
	depends on BR2_PACKAGE_WAFFLE_SUPPORTS_GLX || \
		BR2_PACKAGE_WAFFLE_SUPPORTS_WAYLAND || \
		BR2_PACKAGE_WAFFLE_SUPPORTS_X11_EGL || \
		BR2_PACKAGE_WAFFLE_SUPPORTS_GBM
	select BR2_PACKAGE_XLIB_LIBX11 if BR2_PACKAGE_WAFFLE_SUPPORTS_GLX || BR2_PACKAGE_WAFFLE_SUPPORTS_X11_EGL
	select BR2_PACKAGE_LIBXCB if BR2_PACKAGE_WAFFLE_SUPPORTS_GLX || BR2_PACKAGE_WAFFLE_SUPPORTS_X11_EGL

I don't think we need a Config.in comment to document those
dependencies. They are anyway waaaay too complicated to be summarized
in a Config.in comment.

You can replace this condition with BR2_PACKAGE_WAFFLE_SUPPORTS_WAYLAND.

This one by BR2_PACKAGE_WAFFLE_SUPPORTS_X11_EGL

And this one by BR2_PACKAGE_WAFFLE_SUPPORTS_GBM

> +WAFFLE_DEPENDENCIES += libegl mesa3d udev

I would say adding mesa3d here in the dependencies is a bit useless,
because libegl is provided by mesa3d anyway when
BR2_PACKAGE_MESA3D_OPENGL_EGL.

You had a "depends on BR2_PACKAGE_HAS_LIBGLES" because waffle can use
OpenGLES. But it seems like a runtime dependency, not a build time
dependency. Could you check this ?

So we would have to rework this to use the dependencies I have
suggested for waffle. Maybe we need to simply "depends on
BR2_PACKAGE_WAFFLE", because it is such a mess to express waffle
dependencies in a correct way ?

If we don't do a "depends on BR2_PACKAGE_WAFFLE", we would have to
replicate waffle dependencies, which is possible. But since for waffle
I suggested to not add a Config.in comment about those dependencies
because they are too complicated, we would also not have a Config.in
comment about those dependencies in piglit. So having the "depends on
BR2_PACKAGE_WAFFLE" is maybe good enough.

The xproto-glproto package no longer exists, this needs to be rebased.

Well, I guess it needs waffle for more than wflinfo, no?

This is surprising, what does it do on the host during the build
process that requires those tools ? Or is it that piglit generates a
report on the target, and then provides a bunch of host tool to process
such reports ?

Also needs adjustment now that xproto_glproto has been removed.

Other than those comments, looks pretty good to me.

Could you address those comments and send an updated version?

Thanks!

I believe this comment will be not correct as soon as the libgbm virtual package
will be merged.

Indeed, I noticed It while rebasing my development branch on master.

It's correct, piglit link with libwaffle-1.

Reports can be processed on the target directly.
I believe it's for the same reason that we need host-numpy.
I think the build system is checking the host-python instead of python for the
target.

I'm not sure how to fix this...

Ok, Thanks for the review.

Indeed, but I wrote this example code for the current master, i.e
without the libgbm virtual package merged. Once it is merged, it is not
only the comment that will be wrong, but also the
BR2_PACKAGE_MESA3D_OPENGL_EGL dependency that will have to be replaced
by BR2_PACKAGE_HAS_LIBGBM.

Thanks,

What "same reason" ?

So you mean that all those Python packages are not needed on the host,
but because the build system is bogus and checks their presence on the
host, we have to have them as dependencies ?

So indeed, there's a macro in cmake/Modules/PythonModule.cmake that is
used to check for Mako, Numpy and Six, and it works by running the host
Python. I imagine they are in fact not needed on the host, and this
macro needs to be adjusted. However, I'm not sure what's the right way
to test if a *target* Python module is available.

Maybe Yegor can help on this ? :-)
