ARM – Kernel 4.0-rc1 – Fix for CuBox-i4 Pro Networking..

Adventures With Linux ™ Posted on February 24, 2015 by RGFebruary 24, 2015

The CuBox-i4 Pro booted Kernel 4.0-rc1 OK, but – although eth0 was present – there was no network connection possible.. I found a similar problem described on the Linux Arm Kernel mailing list:  http://lists.infradead.org/pipermail/linux-arm-kernel/2015-February/325249.html According to the info there, I changed linux/arch/arm/mach-imx/mach-imx6q.c as follows: Around line 214, change clksel = ptp_clk == enet_ref ? IMX6Q_GPR1_ENET_CLK_SEL_ANATOP : IMX6Q_GPR1_ENET_CLK_SEL_PAD; … Continue reading →

ARM – Kernel 4.0-rc1 – Not Much Joy….Yet..

Adventures With Linux ™ Posted on February 23, 2015 by RGFebruary 23, 2015

Tried Kernel 4.0-rc1 on the CuBox-i4 Pro (from kernel.org) and the Odroid U3 (from https://github.com/tobiasjakobi/linux-odroid/tree/odroid-4.0.y), and the results are a bit of a mixed bag.. The CuBox boots OK, but – although eth0 appears to be present – networking doesn’t work.. Fedora release 22 (Twenty Two) Kernel 4.0.0-rc1 on an armv7l (ttymxc0) ……………. [root@rgcubox ~]# uname -a … Continue reading →

NVIDIA – Driver Fix, for Kernel 4.0. and Earlier..

Adventures With Linux ™ Posted on February 23, 2015 by RGFebruary 23, 2015

I have hacked together a kernel-version-friendly fix for the latest NVIDIA driver (346.35) which works with Kernel 4.0-rc1 (and later) and also for previous kernel versions..   Thanks are due to juston_li for producing the actual code changes needed..  https://devtalk.nvidia.com/default/topic/813458/linux/linux-4-0-rc1-346-35-build-error-_cr4-functions-fix/ Unpack the NVIDIA driver: ./NVIDIA-Linux-x86_64-346.35.run -x Edit NVIDIA-Linux-x86_64-346.35/kernel/nv-pat.c Around line 34, change { unsigned long cr0 = read_cr0(); … Continue reading →

Kernel – Welcome to Linux 4.0? VMware (Patched) OK, NVIDIA Fix Available..

Adventures With Linux ™ Posted on February 23, 2015 by RGFebruary 23, 2015

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 →

ARM – Raspberry Pi ‘Classic’ – Device Tree Kernel Compile..

Adventures With Linux ™ Posted on February 22, 2015 by RGFebruary 22, 2015

After my tests compiling the new armv7 Pi 2 Kernel – with ‘device tree’ – I decided to try the same with the ‘classic’ armv6 Pi (B+).. You will need the latest version of the Pi /boot files, including the latest config.txt with the necessary parameters for device tree boot, sound config, etc.. For cross-compilation, I created … Continue reading →

ARM – Raspberry Pi 2 – Kernel Compile..

Adventures With Linux ™ Posted on February 19, 2015 by RGFebruary 19, 2015

Finally got the Raspberry Pi 2, and installed Fedora 21 (armv7hl) with no problems..    Temporarily used object code 3.18.7-v7+ from the repository, and then tested kernel compile options.. The system seems (so far..) to be relatively sluggish compared to my other quad-core armv7 systems..   Compiling on the Pi 2 itself seemed relatively slow, but at least it … Continue reading →

VMware – 11.1 Released – Still Broken with Kernel 3.19..

Adventures With Linux ™ Posted on February 18, 2015 by RGFebruary 18, 2015

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..  http://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 →

ARM – Odroid U3 Fan Control – Success..

Adventures With Linux ™ Posted on February 15, 2015 by RGFebruary 15, 2015

Updated the Odroid U3 to the latest version of odroid-3.19.y (# git clone -b odroid-3.19.y –single-branch https://github.com/tobiasjakobi/linux-odroid ). After checking that all the pwm-fan and temperature options were selected in the kernel config, I set ‘Default Thermal governor‘ to ‘step-wise‘. After compiling/installing, I tried some more tests: Using ‘stress’ to raise the temperature: # stress –cpu 4 … Continue reading →

RPM – Fixing ‘Ancient’ Source Rebuilds..

Adventures With Linux ™ Posted on February 12, 2015 by RGFebruary 12, 2015

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 →
