h1. EC20 Linux
h2. Kernel Version
It is using a modified version of a [[Qualcomm_Kernel]] which is available from https://source.codeaurora.org/quic/femto/kernel/msm
<pre>
$ for rev in `git tag | grep \^LNX.LE.2`; do patchsize=$(git diff -w $rev | wc -l); echo $patchsize $rev; done
19247 LNX.LE.2.0-23056-9x15
19188 LNX.LE.2.0-23060-9x15
19188 LNX.LE.2.0-23061-9x15
127972 LNX.LE.2.0-23115-9x15
</pre>
based on this we can see that the EC20 is using a @LNX.LE.2.0-23060-9x15@ derived version with about 19k lines of residual diff of Quectel specific changes.
