There has been some speculation about the ‘Unified Memory’ module found in the latest drivers, but details are somewhat sparse.. From the product Release Highlights: ……….. ”Added nvidia-uvm.ko, the NVIDIA Unified Memory kernel module, to the NVIDIA Linux driver package. This kernel module provides support for the new Unified Memory feature in an upcoming CUDA release.” More … Continue reading →
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 →
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 →
As NVIDIA still seem to be unable to produce an up-to-date driver, there are a bewildering number of ‘patches’ out for various kernel versions and driver combinations.. I have found a good link to a ‘3.11’ patch for NVIDIA driver 331.17 and kernel 3.12 (patching just nv-linux.h) here: http://pastebin.com/gxKDqu9N I would normally credit the author, but it … Continue reading →
Just updated the DreamPlug to kernel 3.12, and – as predicted by Adam Baxter in a recent comment – the ‘mdio/ethernet’ patch was not included.. Details of the patch are in an earlier article: https://rglinuxtech.com/?p=897 With the patch, everything seems to be OK.. I still get occasional ‘hangs’ when running yum/rpm, but that has been a problem … Continue reading →
I updated the DreamPlug to kernel 3.12-rc7, but found that the network problem from 3.12-rc6 was still there, so applied the ‘Ethernet patch’ mentioned in my earlier article – https://rglinuxtech.com/?p=897, and it works OK, now. # uname -a Linux rgdreamplug 3.12.0-rc7 #1 PREEMPT Mon Oct 28 10:07:38 GMT 2013 armv5tel armv5tel armv5tel GNU/Linux Robert Gadsdon. October 28, … Continue reading →
I had assumed that my previous article on ‘auto patching’ was going to be redundant… However, I discovered to my dismay that even the newly-released NVIDIA driver – 331.17 still fails to compile and install on 3.11 and 3.12 kernels.. It appears that nv-drm.c has been fixed, but not nv-linux.h. This means that – for both 3.11 … Continue reading →
As we seem to be stuck for some time with NVIDIA drivers incompatible with the latest kernels, patching seems to be more of a necessity, now. Thanks to a comment from Giordano, I have learned of a way to ‘automatically’ patch any NVIDIAxxxxxx.run file directly, and re-create a corresponding NVIDIAxxxxxx.run file which includes the patch.. The help … Continue reading →
Soon after updating the DreamPlug to 3.12-rc6, I noticed that the Ethernet connection kept dropping, even though the # route command still showed it as OK.. I found a patch for the problem, and it works – for me.. http://www.spinics.net/lists/arm-kernel/msg281285.html Be aware…. this patch is still being tested, and may be changed before it is ‘officially’ released, … Continue reading →
After a lot of ‘frantic testing’, and help from the linux-arm-kernel mailing list, I now have 3.12-rc6 running on the DreamPlug, using the new/improved ‘device tree’.. Fedora release 18 (Spherical Cow) Kernel 3.12.0-rc6 on an armv5tel (ttyS0) …………………. # uname -a Linux rgdreamplug 3.12.0-rc6 #1 PREEMPT Mon Oct 21 13:29:27 BST 2013 armv5tel armv5tel armv5tel GNU/Linux My … Continue reading →
