Vivante driver question

angelo_d — Wed, 08 Jun 2016 13:47:35 GMT

Hi all,

we was successfully using kernel 3.14.28 on imx6q, graphic part was performing quite well. We are moving now to

imx6q-plus. Seems 3.14.28 vivante driver is not supporting imx6q-plus vivante gpu-s. Is this correct ? Is a kernel upgrade in case the only (not really the faster) solution ?

many thanks,

angelo

Hi Angelo

according to attached Release Notes L3.14.28 does not

support i.MX6DQP, it supported starting from 3.14.52.

Best regards

Hi Igor,

many thanks,

so i updated to 3.14.52 (even if from linux-imx-boundary branch) but i get the following error on display init:

[user@localhost ~]$ ./triangle
init(): entering
fsl_getNativeDisplay(): entering

init(): egldispaly is invalid = 00000000
triangle: main.c:153: init: Assertion `eglGetError() == 0x3000' failed.
Aborted (core dumped)

In particular, it is the line

eglInitialize(egldisplay, NULL, NULL);

returning BAD_ALLOC

if any help, welcome.

Thanks,

angelo
