While testing on a PC target with an HD6310 graphic card, the
OpenGL support was in "compat profile" mode (i.e OpenGL 2.1).

OpenGL ES profile version string: OpenGL ES 2.0 Mesa 17.0.2

It turn out that texture float support was missing...

crosscompiling if host == target:
checking whether to enable assembly... yes, x86_64
It was also disabled in the mesa package in Fedora since 7.6 [1].

Hi,
wondering why Kodi already prints
NOTICE: GL_VERSION = 3.0 Mesa 17.0.2
during startup on my system without your patch and
BR2_PACKAGE_MESA3D_DRI_DRIVER_I965=y I investigated its changes and
compiled this defconfig (snipped non-mesa3d options):
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_NOUVEAU=y
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_R600=y
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_SVGA=y
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_SWRAST=y
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_VIRGL=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_SWRAST=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_I915=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_I965=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_NOUVEAU=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_RADEON=y
BR2_PACKAGE_MESA3D_OSMESA=y
BR2_PACKAGE_MESA3D_OPENGL_ES=y
BR2_PACKAGE_XORG7=y
with
BR2_PACKAGE_MESA3D_OPENGL_TEXTURE_FLOAT=y
and without your patch.
The directory output/target/usr/lib/dri/ contains these files, I added a
note when the filesize changed due to --enable-texture-float:
i915_dri.so
i965_dri.so
kms_swrast_dri.so (changed)
nouveau_dri.so (changed, same as kms_swrast_dri.so)
nouveau_vieux_dri.so
r600_dri.so (changed, same as kms_swrast_dri.so)
radeon_dri.so
swrast_dri.so (changed, same as kms_swrast_dri.so)
virtio_gpu_dri.so (changed, same as kms_swrast_dri.so)
vmwgfx_dri.so (changed, same as kms_swrast_dri.so)
libGL.so/libEGL.so/libGLES*.so stayed unchanged.
Afaics the reason why the Intel drivers are unaffected could be this line
of code where texture float support is always enabled:
https://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/drivers/dri/i965/
intel_extensions.c?h=17.0#n83
Other parts of the mesa3d contain #ifdef, like this:
https://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/main/extensions.c?
h=17.0#n134
I am not familiar with the internal structures of mesa3d beyond my
observations, maybe you should add a note to Config.in that your
configure option does not affect all drivers.

Indeed, I saw the ifdef TEXTURE_FLOAT_ENABLED in mesa/main/extensions.c while
checking what --enable-texture-float was doing, but I didn't noticed that it was
always enabled for Intel devices...
It's seems a bug in mesa/drivers/dri/i965/intel_extensions.c which is not
affected by this option...

Me too, I spent several hours searching why OpenGL was in compat mode with the
system produced by Buildroot... I tested the same target with Fedora and noticed
that OpenGL 3.3 was enabled.
Ok, I'll add a note about this.
Do you have any comment on the following patches of this series ?

Romain

Hi,
I am unsure about this patch, why shouldn't we use asm code when
crosscompiling for host == target CPU?
Fedora disabled it due to problems with selinux, Gentoo did something
similar: https://gitweb.gentoo.org/repo/gentoo.git/tree/media-libs/mesa/
mesa-17.0.2.ebuild#n302.
Debian disabled asm only for x32: https://anonscm.debian.org/git/pkg-xorg/
lib/mesa.git/tree/debian/rules?h=debian-experimental#n111

Hi,
no, because I am neither using a gallium driver nor libvdpau I can not
run-time test the changes.
For the asm patch I sent another comment.

To be honest I don't really have an issue with assembly being enabled for my use
case. But there is an issue when you want a reproducible build with the same
defconfig build on a x86 and x86_64 host.
Let see what other think.
Best regards,
Romain

For which architectures is the assembly code available? We should
forcefully enable it for those architectures.
I agree with Romain that we shouldn't depend on something that looks at
the architecture of the host machine to decide if a feature for the
target should be enabled or not.

Since you're the mesa3d developer in Buildroot, I believe a review from you
would be enough to help maintainers to merge these patches.
I'm not asking you to do a runtime test ;-)

Assembly code is available for x86, x86_64/amd64 and sparc (see configure.ac).
The issue while cross-compiling is when assembly are enabled, the build system
build and run a small tool called gen_matypes on the host.
"disable if cross compiling on x86/x86_64 since we must run gen_matypes"
So it allow to enable assembly code while cross-compiling only when the host =
target.

I believe we don't have the choice... we need to disable it.

Romain

Applied to master, after:
- Rewrapping the Config.in help text
- Adding a note that the option doesn't affect all drivers, as per the
discussion with Bernd.
Thanks!

Applied to master, thanks. There was a typo in the commit title, but I
saw it right after pushing, so too late.

Applied to master, thanks. However, it would be good if you could take
