Adventures With Linux ™ Posted on by

Updated the DreamPlug to kernel 3.12.2, and the orion / mdio patch mentioned in the article for 3.12.1 is still needed..

Adventures With Linux ™ Posted on by

Although the latest NVIDIA drivers compile OK on kernel 3.13-rc1, they do not load/run correctly, and may only give low-res output… The same problem exists with the newest version just released – 319.76.. nvidia: Unknown symbol acpi_os_wait_events_complete (err 0) There is a fix available, in this thread from DevZone: https://devtalk.nvidia.com/default/topic/644906/331-20-on-3-13-rc1-kernel/ – but note the logic correction mentioned … Continue reading →

Howto: Cross-Compiling for ARM – One Method..

Adventures With Linux ™ Posted on by

I originally wrote an article on cross-compiling for ARM systems, some time ago – before I got my first Raspberry Pi – and this is a more up-to-date version. This is how I cross-compile ARM kernels, on x86_64.  There are – of course – other ways of doing this, but this works, for me.. The following info … Continue reading →

Pidora – 19 Alpha – Revived?

Adventures With Linux ™ Posted on by

Thanks to a comment from Mace Moneta, I learned that there is an ‘alpha release’ of Pidora 19 now available: https://lists.fedoraproject.org/pipermail/arm/2013-November/007021.html It was a little odd that no mention of this could be found on the Pidora website or Wiki, but hopefully these will be updated in due course.. Pidora release 19 (Raspberry Pi Fedora Remix) Kernel … Continue reading →

NVIDIA – Finally… Up to Date..!

Adventures With Linux ™ Posted on by

After considerable delays, NVIDIA have finally released up-to-date drivers that support 3.11 and 3.12 kernels, without the need for patches.. I have tested 319.72 and 331.20, and both compile OK, on kernels 3.11 and 3.12.. Hopefully NVIDIA will be able to maintain their Linux driver/kernel compatibility, after this uncharacteristic lapse..
