Kernel 4.10-rc2 has been released, and it has a very small number of changes from -rc1: http://lkml.iu.edu/hypermail/linux/kernel/1701.0/00069.html I suspect that the major reason for this release is to fix the embarrassing compile fail with ARM64/aarch64, and it does compile OK now (tested on the Odroid C2).. Robert Gadsdon. January 2, 2017.

I had been trying to apply the latest round of Meson TX delay patches to the latest linux-next tree, but found that there seems to be a conflict with some of these.. The December 1 patched kernel now has some problems on my C2 with Ethernet traffic, so – for the time being – I have reverted … Continue reading →
Updated the test system to Kernel 4.9-rc3, and the patch for NVIDIA mentioned in my article for -rc2 still works OK.. I Compiled 370.28 and 375.10 successfully.. As I could not find any patches for VMware – and the latest version 12.5.1 still fails to compile, I created a nasty hack myself.. Warning – This is not … Continue reading →

I was going to update the Odroid C2 to the latest patched kernel, but then found that the meson-mmc driver had mysteriously vanished from the source tree.. This – of course – makes the kernel pretty useless… I did some research, but could not find any specific mention of the removal of this code, but then found … Continue reading →
I tried the latest ‘Linux-Next’ version, from https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/?id=refs/tags/next-20160913 and the C2 booted OK, but the Ethernet problem still persists.. ……… eth0: device MAC address 00:1e:06:33:13:6e meson6-dwmac c9410000.ethernet eth0: Link is Up – 1Gbps/Full – flow control rx/tx Fedora 24 (Workstation Edition) Kernel 4.8.0-rc6-next-20160913 on an aarch64 (ttyAML0) ………………… # uname -a Linux rgc2 4.8.0-rc6-next-20160913 #2 SMP PREEMPT … Continue reading →
