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 →
Thanks to Al Viro, and to coderus on the VMware forum, we now have a solution for vmnet and Kernel 3.19, as follows: In vmnet-only/driver.c (lines 269, 1194, and 1195): Replace instances of f_dentry with f_path.dentry In vmnet-only/userif.c (line 526): Replace return skb_copy_datagram_iovec(skb, 0, &iov, len); with struct iov_iter to; iov_iter_init(&to, READ, &iov, 1, … 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) ………………..

Tested the lates NVIDIA driver (346.35) today, and although it fixes the f_dentry error, the compile still fails with Kernel 3.19-rc4, due to the incompatible GPL problem: FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘__cachemode2pte_tbl’ /usr/src/linux-3.19-rc4/scripts/Makefile.modpost:90: recipe for target ‘__modpost’ failed It has been pointed out that this can be fixed by simply changing the license … Continue reading →
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 system to Kernel 3.19-rc3, and there is still no fix for VMware (11.0) and the latest NVIDIA (340.65 and 346.22) drivers… The NVIDIA problem will involve getting around a GPL-incompatible module issue.. FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘__cachemode2pte_tbl’ 3.19-rc3 installs and runs OK on the CuBox-i4 Pro: $ uname -a Linux … 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 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!
