ARM64 – DragonBoard 410c to Kernel 4.1..

Adventures With Linux ™ Posted on July 2, 2015 by RGJuly 2, 2015

Managed to update the DragonBoard 410c to Linaro Kernel 4.1.0+, from here: git clone https://git.linaro.org/landing-teams/working/qualcomm/kernel.git -b integration-linux-qcomlt So far, I have made the kernel ‘monolithic’ with all necessary modules built-in (‘y” instead of ‘m’), as this was how the original Linaro/Qualcomm kernel was built..     As the 410c uses the android fastboot, it would seem that the kernel/boot … Continue reading →

NVIDIA – Kernel 4.1 GPL-only Fixed

Adventures With Linux ™ Posted on May 7, 2015 by RGMay 7, 2015

The GPL error with NVIDIA drivers and kernel 4.1-rc has been fixed with a patch to linux/arch/x86/kernel/process.c Details are at http://lkml.iu.edu/hypermail/linux/kernel/1505.0/03818.html.    EXPORT_PER_CPU_SYMBOL_GPL(cpu_tss); has been replaced by EXPORT_PER_CPU_SYMBOL(cpu_tss); I have applied the patch to Kernel 4.1-rc2, and rebooted, and NVIDIA driver 346.59 now compiles and loads OK..

ARM – More SELinux Problems..

Adventures With Linux ™ Posted on May 6, 2015 by RGMay 6, 2015

After updating the Odroid U3 to kernel 4.1-rc2 (see separate post) I encountered more SELinux / Fedora 22 issues.. This time, SELinux tried to enable itself in ‘targeted’ mode on reboot, despite being ‘disabled’ in the config file.. …. [ OK ] Started Tell Plymouth To Write Out Runtime Data. [ OK ] Started Preprocess NFS configuration. … Continue reading →

ARM – Rogue SELinux Fixed..?

Adventures With Linux ™ Posted on May 5, 2015 by RGMay 5, 2015

I updated the CuBox-i4-Pro (Fedora 22) to Kernel 4.1-rc2, but the (re)boot process was very sluggish, with several key commands failing: ….. systemd[1]: Unit dbus.service entered failed state ….. [FAILED] Failed to start Login Service. ….. [FAILED] Failed to start Modem Manager. ….. [FAILED] Failed to start Avahi mDNS/DNS-SD Stack. …..

Kernel – Pre-4.1-rc Test with Linux-Next..

Adventures With Linux ™ Posted on April 26, 2015 by RGApril 26, 2015

As Kernel 4.1-rc1 is not released yet, I tested the April 24 version of linux-next, to see how VMware and NVIDIA compiles would behave.. # uname -a Linux rg6830l 4.0.0-next-20150424 #2 SMP Sun Apr 26 12:04:54 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux With this version, VMware 11.1 (with the 3.19 vmnet patch) compiled and loaded OK, but … Continue reading →

Kernel – 4.1 will be ‘Interesting’ for x86…

Adventures With Linux ™ Posted on April 24, 2015 by RGApril 24, 2015

The initial release of Kernel 4.1-rc1 should be out fairly soon, but this time it might possibly break some things..?. There will be a lot of ‘improvements’ to x86-related code:  http://lkml.iu.edu/hypermail/linux/kernel/1504.1/03389.html. So – we have been warned!

ARM – Pi to 4.0.. Patience is a Virtue..?

Adventures With Linux ™ Posted on April 14, 2015 by RGApril 14, 2015

Tried updating the Raspberry Pi-s (Classic model B and Pi2) to Kernel 4.0, from https://github.com/raspberrypi/linux/tree/rpi-4.0.y, and my first attempt was – it seems – too soon, as the Classic Pi (armv6) failed to boot at all, and the Pi2 (armv7) only booted as far as: …………. bcm2708_dma: DMA manager at f3007000 bcm2708_gpio: bcm2708_gpio_probe 80625490 vc-mem: phys_addr:0x00000000 mem_base=0x3dc00000 … Continue reading →
