NVIDIA have released driver 319.82, and now 331.38, and they install OK on kernel 3.12, but – unfortunately – still need the patch for kernel 3.13, despite the fact that 3.13 Final is due in about a week from now.. modprobe: ERROR: could not insert ‘nvidia’: Unknown symbol in module, or unknown parameter (see dmesg) make[1]: *** [package-install] … Continue reading →
ARM devices on Linux are rapidly moving to use the ‘device tree‘ format to specify the CPU / SoC characteristics at kernel compile time, for producing the boot image… For systems such as the DreamPlug, this means that the old # make uImage is no longer applicable.. For the DreamPlug, this is an example of the … Continue reading →
Updated the test system to kernel 3.13-rc4, and VMware 10.0.1 and (patched) NVIDIA 331.20 compile and load OK.. NVIDIA appear to have pulled driver version 319.76 from their ftp download site – ftp://download.nvidia.com/XFree86/Linux-x86_64/, for some reason.. Robert Gadsdon. December 16, 2013. … Continue reading →
Thanks to more detective work by Adam Baxter, I have found a work-in-progress patch for the compile failure on 3.13-rc.. http://article.gmane.org/gmane.linux.ports.arm.kernel/282669 So.. I now have Kernel 3.13-rc3 running on the DreamPlug: Fedora release 18 (Spherical Cow) Kernel 3.13.0-rc3 on an armv5tel (ttyS0) ………………….. # uname -a Linux rgdreamplug 3.13.0-rc3 #2 PREEMPT Sat Dec 7 15:02:56 GMT 2013 … Continue reading →
Updated the DreamPlug to kernel 3.12.2, and the orion / mdio patch mentioned in the article for 3.12.1 is still needed.. (http://rglinuxtech.com/?p=941) I have tried to compile 3.13-rc kernels for the device, but the compilation fails: /linux-3.13-rc2/arch/arm/include/asm/memory.h: In function ‘__virt_to_phys’: ……………… /linux-3.13-rc2/arch/arm/include/asm/memory.h:244:40: error: ‘PHYS_OFFSET’ undeclared (first use in this function)…………………… make[1]: *** [arch/arm/kernel/asm-offsets.s] Error 1 make: *** … Continue reading →
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 →
Just updated the DreamPlug to Kernel 3.12.1, and found that the Ethernet/network problem from 3.12 is still there… The not-yet-implemented orion_mdio patch is still needed..- see: http://rglinuxtech.com/?p=897 $ uname -a Linux rgdreamplug 3.12.1 #1 PREEMPT Thu Nov 21 14:32:15 GMT 2013 armv5tel armv5tel armv5tel GNU/Linux Robert Gadsdon.

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 →
