[Pixman] SIGBUS in pixman_composite_src_0565_0565_asm_neon

[hubert-b at gmx.de]

Hi pixman developers!

I'm trying to get X to run on my private IGEP board with an Multiinno-Display. The display is attached via SPI and so far, it is working (e.g. I can use the framebuffer console "fbcon" without problems).

But when I start Xfbdev, I get the below listed error. I'm using pixman 0.24.2 on poky linux. I also already tried to delve into the pixman code, but the content of pixman-arm-neon-asm.h is not quite easy understandable to me (at least not within the 60 minutes I spent on it).

Any idea will be appreciated!

Best regards and thanks in advance!
Andreas
