Ah, I assumed the default to be at the 4.9-2.3.x-imx branch. That one
is based upon 4.9.166, which is much more close to the latest upstream.
Now I’m wondering if I have the wrong version of meta-freescale. The
recipes-kernel/linux directory contains the following files:
linux-qoriq_4.19.bb
linux-imx_4.9.123.bb
linux-fslc-lts-4.19.bb
linux-fslc-imx_4.9-1.0.x.bb
linux-qoriq_4.14.bb
linux-imx-headers_4.9.123.bb
linux-fslc-imx-rt_4.1-2.0.x.bb
linux-fslc_5.0.bb
linux-imx-mfgtool_4.9.123.bb
No, looks fine. Just tip of Warrior branch.
I guess I could use linux-imx_4.9.123 to get me a bit further forward or
bbappend linux-fslc-imx_4.9-1.0.x.bb and pull the latest SRVREV out of
git://github.com/Freescale/linux-fslc.git
That one seems to be targeted by NXP at supporting the i.MX8 series (only).
Maybe Otavio can shed some light on what best to use. The most recent
FSL Community work seems to be done at the 4.9-2.3.x-imx branch (just a
week ago).
A recent kernel from a longterm branch is probable the best to have.
However, I feel that it is mostly important later in the development.
Starting with defaults usually gets you going without too much hassle.
For small, short-lived projects, starting with any LTS kernel is fine
as long as you get to a recent one before release. With larger and
long-living developments, you have to cater for major kernel version
jumps anyway.
The default 4.9.67 boots and I have run the initial tests on it
successfully. I was looking to update it to something that would be a
better long term option if this test exercise turns into a full product
development.
Maybe postpone that update and stick to 4.9.67 and work on the stuff you
need to do.
Having built the 4.19.66 kernel with the changed KERNEL_DEVICETREE
setting I now have a compile issue with the Vivante drivers which
appears to come from some DMA related functions having moved header file
somewhere along the way.
My bet would be to stick to something 4.9-ish (or possible 4.14 from
4.14-2.0.x-imx branch) as they will be supported for a very long time,
see <https://www.kernel.org/category/releases.html> and will stay most
likely compatible with your current Vivante drivers.
