I have tried the latest 4.7-next patched kernel, from https://github.com/anholt/linux/tree/bcm2837-64-next After some trials, I did manage to – just – get it to boot – after falling to an ’emergency console’, but the system is very unstable, with multiple recurring MMC errors.. …..

Just tested the latest NVIDIA driver – 367.27 – and it fails to compile with Kernel 4.7-rc3. To fix this, the patch for 367.18 still works ( details at http://rglinuxtech.com/?p=1750 ). ………………..

I recently obtained one of the newly-released (- to the ‘public’..) Pine64 ARM64 systems… My first reaction, was that it is a bit on the large side.. The board is over twice the size of the Odroid C2.. As usual, the ‘standard’ U-Boot was a heavily-customised old version, that only mounted Android-format Kernel ‘blob’s, but a hacked … Continue reading →

Thanks to juston_li on the NVIDIA Devtalk forum, there is specific detail of the changes needed for Kernel 4.7 compatibility.. Details are at https://devtalk.nvidia.com/default/topic/938665/linux/linux-4-7-rc1-367-18-build-errors/ The first issue is interesting, as it is due to a Kernel Dev. deciding to introduce a new variable – radix_tree_empty – in Kernel 4.7-rc1, that happens to have the same name as … Continue reading →
Thanks to g, from their comment on my previous article ( http://rglinuxtech.com/?p=1746 ), there may be a more correct vmnet fix than simply ‘commenting out the code’.. Replace dev->trans_start = jiffies with netif_trans_update(dev) in netif.c I have made this change, and VMware 12.1.1 is – so far – loading and running OK, as usual.. Robert Gadsdon.
