* Vivante GPU on i.MX6solo @ 2014-03-24 15:13 Gary Thomas 2014-03-25 2:07 ` Otavio Salvador 0 siblings, 1 reply; 7+ messages in thread From: Gary Thomas @ 2014-03-24 15:13 UTC (permalink / raw) To: meta-freescale@yoctoproject.org I have a board which uses the i.MX6solo chip. This CPU (SOC) has a different GPU than its cousins i.MX6Q and i.MX6dual. When I try to run anything using the accelerated graphics, e.g. X server using the Vivante libraries, it crashes hard. I know that my SOC has a Vivante GC880 whereas the i.MX6Q uses the Vivante GC2000. Is there any way to get Vivante GPU support for my board/SOC?

Well, it is lacking a lot of information so it is quite hard to guess. My guess is that you have an old BSP kernel and without the 4.6.9p13 patches. When those things happen you see a segfault in Xorg initialization using the Vivante drivers. Good luck debugging. -- Otavio Salvador O.S.

This well could be - I use the linux-boundary recipe for 3.0.35+ (my board is nearly identical to a SabreLite from Boundary Devices) I'm a bit confused by the '4.6.9p13' reference. Is that part of a GPU recipe version? or a kernel version? Can you point me to any discussion of this, or the kernel (which tree) revision that made this change, etc?
