Peter, All,
On 2020-12-23 23:45 +0100, Peter Seiderer spake thusly:
> A starting point to add some/more Vulkan support to Buildroot.
>
> Targeting towards the RPi Vulkan support (as announced e.g. [1]),
> but send as RFC as not (yet) functional:
>
> - did only try to run standalone and/or with Qt EGLFS, but
> did not work out as the broadcom vulkan driver is only
> functional with X11/XCB
>
> - the Qt Vulkan support seems only be functional with
> EGLFS/Vivante and/or X11/XCB
Speaking of which: have you seen this series:
https://patchwork.ozlabs.org/project/buildroot/list/?series=157522
package/opengl/libopenvx: new virtual package
package/opengl/libvulkan: new virtual package
package/freescale-imx/imx-gpu-viv: add options for new feture
The last one introduces imx-gpu-viv as a provider for libvulkan, so at
least it does not seem to contradict your assumptions that Vulkan is
possible with Vivante. ;-)
Regards,
Yann E. MORIN.
