[Buildroot] [PATCH 1/2] package/sunxi-mali: reorder select/depends

[Romain Naour]

From [1]:
"Even though the ordering has absolutely no consequences in Kconfig, it
is not logical (when reading). It is more logical and far easier to
understand when depends come first, followed by the selects."

Also, the Config.in example in the manual suggests to use this coding
style [2].

[Buildroot] [PATCH 2/2] package/sunxi-mali: remove sunxi-mali r2p4 kernel module

[Romain Naour]

sunxi-mali r2p4 kernel module are linked against libUMP.so.2 but libump
package in Buildroot only provide libUMP.so.3, see [1].

 ./r2p4/armhf/x11/libGLESv2.so.2.0
 ./r2p4/armhf/x11/libMali.so
- 0x00000001 (NEEDED)                     Shared library: [libUMP.so]
+ 0x00000001 (NEEDED)                     Shared library: [libUMP.so.2]
 ./r2p4/armhf/x11/libGLESv1_CM.so.1.1
 ./r2p4/armhf/x11/libEGL.so.1.4
  0x00000001 (NEEDED)                     Shared library: [libX11.so.6]
  0x00000001 (NEEDED)                     Shared library: [libdrm.so.2]
  0x00000001 (NEEDED)                     Shared library: [libXfixes.so.3]
  0x00000001 (NEEDED)                     Shared library: [libXext.so.6]
 ./r2p4/armel/framebuffer/libGLESv2.so
 ./r2p4/armel/framebuffer/libMali.so
- 0x00000001 (NEEDED)                     Shared library: [libUMP.so]
+ 0x00000001 (NEEDED)                     Shared library: [libUMP.so.2]
 ./r2p4/armel/framebuffer/libGLESv1_CM.so
 ./r2p4/armel/framebuffer/libEGL.so

So any program or library trying to link with -lGLESv2 will fail with
the following error:

arm-none-linux-gnueabi/bin/ld: warning: libUMP.so.2, needed by
output/host/usr/arm-buildroot-linux-gnueabi/sysroot/armv4t/usr/lib/libMali.so,

Since nothing provide libUMP.so.2, remove BR2_PACKAGE_SUNXI_MALI_R2P4
option and add BR2_ARM_EABIHF dependency directly to sunxi-mali
package.

Also the defconfig olimex_a20_olinuxino_lime_mali_defconfig maintained
by Francois Perrad, is an ARM EABIHF system.

[Buildroot] [PATCH 2/2] package/sunxi-mali: remove sunxi-mali r2p4 kernel module

[Yann E. MORIN]

Romain, All,

On 2017-02-18 15:52 +0100, Romain Naour spake thusly:
> sunxi-mali r2p4 kernel module are linked against libUMP.so.2 but libump
> package in Buildroot only provide libUMP.so.3, see [1].

OTOH, it looks like the versioning is just arbitrary:

    https://github.com/linux-sunxi/libump/commit/1c1f6337dffffe8f7aea98f710f681727ed45f4f

    We prefer version 3, as r2pX is pretty rare by now, but if needs be,
    this can be easily changed.

So maybe libump could add a legacy symlink libUMP.so.2 -> libUMP.so.3 ?

Regards,
Yann E. MORIN.

Yes probably in this specific case but doing so is generally highly not
recommended :p
Also since r2pX was pretty rare back in 2013, I don't think it's a big loss.

A kernel module cannot be linked against a userspace shared library, so
the commit title and this description do not make sense. Perhaps you're
talking about the libGLES library?

Please use:

	needs an EABIhf glibc toolchain

instead.

Thanks!

Yes obviously...

I'm speaking about the libGLES library provided by sunxi-mali for r2p4 mali
kernel module. This library is linked against libUMP.so.2 but libump package in
Buildroot only provide libUMP.so.3.

As far I understand, r3p0 and r3p1 are the version of the mali kernel module
which create /dev/mali and /dev/ump devices and require libUMP.so.3.

See: http://linux-sunxi.org/Mali_binary_driver

Ok my comments wasn't good, let me respin...

Best regards,
Romain
