I had been running Kernel 4.2 on my main system since it was released, but have been experiencing vague and inconsistent problems with sluggish applications, which sometimes hung for about half-a-second.. Nothing specific, and no apparent errors reported.. I reverted to Kernel 4.1.7, and everything seems to be back to normal.. I will try 4.2.1 as soon … Continue reading →
Just updated the Qualcomm DragonBoard 410c to Linaro/Qcom patched Kernel 4.2, from here: https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/tree/refs/heads/integration-linux-qcomlt Using the saved kernel config from 4.2-rc5, the system booted OK (headless)..: Fedora release 23 (Twenty Three) Kernel 4.2.0 on an aarch64 (ttyMSM0) ……………. # uname -a Linux rg410c 4.2.0 #1 SMP PREEMPT Sun Sep 13 20:13:35 PDT 2015 aarch64 aarch64 aarch64 GNU/Linux … Continue reading →
Updated the test system to Kernel 4.3-rc1.. $ uname -a Linux rg6830l 4.3.0-rc1 #1 SMP Sat Sep 12 19:15:35 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux Brief details of changes are here: http://lkml.iu.edu/hypermail/linux/kernel/1509.1/03200.html The NVIDIA gpl_only issue has been fixed in linux/kernel/workqueue.c, but the compile now fails even before that is reached: /home/rgadsdon/NVIDIA-Linux-x86_64-355.11/kernel/nvidia/nv-procfs.c: In function ‘nv_procfs_read_registry’: /home/rgadsdon/NVIDIA-Linux-x86_64-355.11/kernel/nvidia/nv-procfs.c:363:12: error: … Continue reading →
Tested the 4.2 Final kernel, and the later NVIDIA drivers still fail to install, with the same GPL-only error.. A simple patch to fix this was proposed for 4.2-rc5, some time ago, but – for some reason – has failed to make it into the ‘final’ release..’ Details of the patch are here: http://lkml.iu.edu/hypermail/linux/kernel/1508.0/02260.html Maybe this will … Continue reading →
Updated the test system to Kernel 4.2-rc6, and the NVIDIA ‘GPL-Only’ problem still persists: Building modules, stage 2. MODPOST 2 modules FATAL: modpost: GPL-incompatible module nvidia.ko uses GPL-only symbol ‘flush_workqueue’ /usr/src/linux-4.2-rc6/scripts/Makefile.modpost:90: recipe for target ‘__modpost’ failed make[3]: *** [__modpost] Error 1 /usr/src/linux-4.2-rc6/Makefile:1389: recipe for target ‘modules’ failed make[2]: *** [modules] Error 2 make[2]: Leaving directory ‘/usr/src/linux-4.2-rc6’ Makefile:146: … Continue reading →
After some more testing, including trying (unsuccessfully) the HiKey version of Kernel 4.1-rc4 # git clone -b hikey-mainline-rebase –single-branch https://github.com/96boards/linux/ I was frustrated by the complete lack of kernel boot info on screen, after the proprietary bootloader had finished.. More research found that this bootloader was described as somewhat deficient in the ‘fit for purpose’ department, and … Continue reading →
Updated the DragonBoard 410c to patched Kernel 4.2-rc1 from https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/tree/refs/heads/integration-linux-qcomlt , and the system booted OK: Fedora release 22 (Twenty Two) Kernel 4.2.0-rc1+ on an aarch64 (ttyMSM0) ……….. # uname -a Linux rg410c 4.2.0-rc1+ #2 SMP PREEMPT Thu Jul 16 15:14:27 PDT 2015 aarch64 aarch64 aarch64 GNU/Linux – But, on further testing, the SD Card (mmc1) had … Continue reading →
One of the most annoying missing features of the HiKey ARM54 board is the lack of a proper UART connection, to enable the same degree of boot information as other SoC systems.. There is a 4-pin/hole connection point, but no actual connector… So, I had to get out the (mini) soldering iron, and magnifying goggles, and use … Continue reading →
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 →
After quite a lot of messing about, I got Fedora 22 running on the ARM64 DragonBoard 410c: Fedora release 22 (Twenty Two) Kernel 4.0.0-linaro-lt-qcom on an aarch64 (ttyMSM0) ………… $ uname -a Linux rg410c rg410c.almaden 4.0.0-linaro-lt-qcom #1 SMP PREEMPT Fri Jun 5 15:17:06 UTC 2015 aarch64 aarch64 aarch64 GNU/Linux Still running the ‘stock’ Linaro/Qualcom version of Kernel … Continue reading →
