[meta-freescale] Image building and deployment to SMARC-sAMX6i

[Heikki Sarkanen]

Hello Dirk,

If you are running something GPU intensive I would recommend upgrading at least to 3.10.53 kernel so then you could use the newer GPU drivers. With daisy/3.10.17 you cannot: https://lists.yoctoproject.org/pipermail/meta-freescale/2015-April/013234.html I have tried Qt 5.4 on X11 and Wayland. Both of them got some performance boost from that update. Although I have not tested how this benefits on FB. It's a bit hard to follow what have changed in Vivante GPU but documents like this one: http://cache.freescale.com/files/32bit/doc/support_info/IMX6YOCTOPATCHRN.pdf at Freescale listing: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&fpsp=1&tab=Documentation_Tab gives some hints. Also this: https://community.freescale.com/docs/DOC-104266 explains something about the compatible versions and all things around Yocto and iMX6.

I didn't have any big issues on the upgrade to 3.10.53 although I skipped some of the backlight related patches. Biggest thing for me was LVDS driver related changes in devicetree: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/commit/arch/arm/boot/dts?h=imx_3.10.53_1.1.0_ga&id=b8a5656180f4eee73437263c58d1973a89454843 But following the Freescale and Congatec examples: https://git.congatec.com/arm/qmx6_kernel/commit/23ba00c5aeabc44decbaf151c733a1add38390cf it was easy though. I would be interested of the results especially if you go straigth to 3.14.28.

And let's hope that Kontron does the official update soonish.

BR,
Heikki

Hello Heikki,

thank you for the informations!

Especially the link to the "gpu performance" thread is very interesting
for me, because we're running a javafx project on top of FB based opengl.

I didn't make the step to fido yet. So it's also interesting for me to
hear about your success.

Kind Regards
Dirk
