Just tested Kernel 4.0-rc1 – announced here: http://lkml.iu.edu/hypermail/linux/kernel/1502.2/04059.html As you will see – not much actual detail on what has changed, and I have already run into a couple of ‘issues’… The Radeon drm driver on my laptop refuses to load, and the boot hangs immediately with drm r600_ring_test [radeon] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xFFFFFFFF) … Continue reading →
Just updated the test system to VMware Workstation 11.1, and – unfortunately – this is still incompatible with Kernel 3.19.. The only good news is.. The vmnet patch for 11.0 still applies, and fixes the problem.. https://rglinuxtech.com/?p=1281 The release notes (for what it’s worth!) are here: https://www.vmware.com/support/ws/doc/workstation-111-release-notes.html As you can see – quite a lot of ‘known … Continue reading →
I had occasion to install an ancient GTK+ app, recently, and had to use # rpmbuild –rebuild xxxxx.src.rpm to (re)create some old RPMs from source.. I got the following error: /home/rgadsdon/rpmbuild/BUILD/php_gtk-1.0.2/main/php_gtk_object.c: In function ‘php_gtk_args_from_hash’: /home/rgadsdon/rpmbuild/BUILD/php_gtk-1.0.2/main/php_gtk_object.c:410:4: error: format not a string literal and no format arguments [-Werror=format-security] php_error(E_WARNING, buf); ^ So, I needed to remove the –Werror=format-security parameter … Continue reading →
Updated the Odroid U3 to (patched) Kernel 3.19, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Thanks to work by tobiasjakobi, this now includes the preliminary patches – updated for 3.19 – for fan control on the Odroid U3, originally posted by Lukasz Majewski at http://www.spinics.net/lists/linux-samsung-soc/msg42259.html So, (on a Fedora 21 system) you can now control the fan, as follows: # echo “0” … Continue reading →
Updated the Odroid U3 to Kernel 3.19-rc7, from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-3.19.y Had to ‘refresh’ the config, by # make exynos4412_odroid_defconfig, and then (re)enable selinux etc… One feature is that the CPU fan no longer runs constantly, but I need to do more tests, to see if it is now capable of running at all.. The temperature is OK, at … Continue reading →
Installed Kernel 3.19-rc7 on the test system, and the same comments apply as for -rc6. The latest NVIDIA driver (346.35) and VMware 11.0 – with the vmnet patches – install and load/run OK.. Changelog summary here: http://lkml.iu.edu/hypermail/linux/kernel/1502.0/00273.html $ uname -a Linux rg6830l 3.19.0-rc7 #1 SMP Mon Feb 2 19:00:25 PST 2015 x86_64 x86_64 x86_64 GNU/Linux It appears … Continue reading →
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 →
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 →

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 →
