After the solution to the Kernel 3.19/vmnet problem mentioned in previous posts, I have produced a fix that includes tests for kernel versions, and works with Kernel 3.19 and with earlier kernel versions.. This is probably not the most elegant code, but it works – I have tested it with VMware 11.0 and Kernels 3.19-rc5 and 3.18.3 … Continue reading →
Updated the Odroid U3 to the patched version of 3.19-rc5, from here: https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Fedora release 21 (Twenty One) Kernel 3.19.0-rc5 on an armv7l (ttySAC1) ………………..

Updated the test system to Kernel 3.19-rc4, and the same comments apply as for -rc3.. Still no fixes for NVIDIA and VMware, yet.. I tried the CuBox-i4 Pro with a ‘standard’ kernel from kernel.org, rather than the ‘patched’ version used previously, and it booted OK.. Fedora release 21 (Twenty One) Kernel 3.19.0-rc4 on an armv7l (ttymxc0) …………. … Continue reading →
Updated the test (Intel) system, and the Cubox-i4 Pro to Kernel 3.19-rc2.. NVIDIA and VMware still do not compile (see 3.19-rc1 article for details http://rglinuxtech.com/?p=1258) and – so far – there does not seem to be a patch for either. The NVIDIA GPL code incompatibility issue may be more convoluted to fix ‘legally’.. I tried more code … Continue reading →
This article relates to compilation on the latest Fedora (21) but can also apply to other Distros… The Distro-supplied version of Audacity is typically functionality-challenged, and does not allow working with some of the more up-to-date audio formats, due to US Patent law concerns.. The necessary functionality can be achieved by compiling it yourself, and this is … Continue reading →
Just updated the Cubox-i4Pro to 3.19-rc1, after disabling the kernel options for ‘power management’, as the current patch does not compile cleanly.. Fedora release 21 (Twenty One) Kernel 3.19.0-rc1 on an armv7l (ttymxc0) ………..

Just installed Kernel 3.19-rc1 on the test system, and both VMware and NVIDIA fail to compile.. VMware (11.0) vmnet failed with: /tmp/modconfig-2fqpf2/vmnet-only/driver.c: In function ‘VNetFileOpUnlockedIoctl’: /tmp/modconfig-2fqpf2/vmnet-only/driver.c:1194:20: error: ‘struct file’ has no member named ‘f_dentry’ if (filp && filp->f_dentry) { ^ /tmp/modconfig-2fqpf2/vmnet-only/driver.c:1195:19: error: ‘struct file’ has no member named ‘f_dentry’ inode = filp->f_dentry->d_inode; ^ scripts/Makefile.build:257: recipe for target … Continue reading →
Yet another ‘lockup’ – this time with 3.18.. So, as the problem also exists with 3.17.x, I have taken the unusual step of reverting to Kernel 3.16.7, for the time being! Some of the latest correspondence on the issue, here: http://lkml.iu.edu/hypermail/linux/kernel/1412.1/03302.html Robert Gadsdon. December 12, 2014. … Continue reading →
Updated the CuBox-i4 Pro to Kernel 3.18, and now use the complete ‘device tree’ zImage and dtb boot method: The source can be found here: https://github.com/jmontleon/fedora-20-cubox-i_hb/tree/3.18.0 – and the u-boot boot commands are: setenv bootargs “root=/dev/mmcblk0p3 rootfstype=ext4 rootwait console=ttymxc0,115200n8 console=tty1 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32” setenv bootcmd “load mmc 0:1 0x10800000 zImage; load mmc 0:1 0x18000000 imx6q-cubox-i.dtb; bootz 0x10800000 – 0x18000000” … Continue reading →
I have managed to get Kernel 3.18-rc7 to boot on my Odroid U3, but it is still very unstable..
