Kernel 3.19-rc6 – Good News for NVIDIA..

Adventures With Linux ™ Posted on January 27, 2015 by RGJanuary 27, 2015

Updated to Kernel 3.19-rc6 on the test system, and – at last – the problem with NVIDIA driver GPL inconsistency has been fixed, and now driver 346.35 compiles and loads OK.. Details of changes since -rc5 are here:   http://lkml.iu.edu/hypermail/linux/kernel/1501.3/00776.html And the important change is that /arch/x86/mm/init.c now has EXPORT_SYMBOL(__cachemode2pte_tbl) instead of EXPORT_SYMBOL_GPL(__cachemode2pte_tbl)..etc.. VMware 11 – with the … Continue reading →

VMware – Backward-Compatible 3.19 Fix..

Adventures With Linux ™ Posted on January 23, 2015 by RGJanuary 23, 2015

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 →

VMware 11 – Fix for vmnet and Kernel 3.19..

Adventures With Linux ™ Posted on January 23, 2015 by RGJanuary 23, 2015

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 →

NVIDIA – New Driver 346.35, Still Fails with 3.19-rc..

Adventures With Linux ™ Posted on January 17, 2015 by RGJanuary 17, 2015

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 →

Kernel 3.19-rc4 – OK on CuBox-i4 Pro.. No fixes yet for NVIDIA and VMware on x86..

Adventures With Linux ™ Posted on January 12, 2015 by RGJanuary 12, 2015

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 →

Kernel 3.19-rc3, ‘Lockup’ Bug, Latest..

Adventures With Linux ™ Posted on January 6, 2015 by RGJanuary 6, 2015

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 →

ARM/Intel – CuBox-i4 Pro to 3.19-rc2, VMware and NVIDIA Still Broken..

Adventures With Linux ™ Posted on January 4, 2015 by RGJanuary 4, 2015

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 →
