Subject: 4.11-rc6 and OF_DYNAMIC
Date: Wed, 12 Apr 2017 11:54:24 +0200 [thread overview]
Message-ID: <2824279.KnFs6MaoZt@dabox> (raw)
Hi
I have been testing the 4.11-rc6 kernel on Intel(ex Altera) Arm SOC Cyclone
with dynamic Firmware loading. As i didn't know how to trigger dynamic
loading from userspace i also applied the following patch:
OF: DT-Overlay configfs interface
https://github.com/raspberrypi/linux/commit/8f1079750ce2fce4c4c2b4f8759ea57c8fb167d3
Now i got the loading of the devicetree overlay working :-)... but only if i enable
OF_UNITTEST. I find this a little strange especially as it slows boot time.
I also tried adding:
select OF_DYNAMIC
to my OF_CONFIGFS patch but this didn't help. Also patching away "if OF_UNITTEST"
config OF_DYNAMIC
- bool "Support for dynamic device trees" if OF_UNITTEST
+ bool "Support for dynamic device trees"
didn't help?
Besides these nitpicks i am really happy to see this in mainline as it really makes working with
dynamic fpga based hardware much cleaner!
Best regards
Tim
