Android – New Year, New Fork?

Adventures With Linux ™ Posted on December 28, 2016 by RGDecember 28, 2016

Now that Cyanogenmod has summarily shut down, there is a planned new forked version, at http://lineageos.org/ Remains to be seen whether this will flourish, and whether it will survive any potential legal shenanigans, but at least it shows one of the core benefits of Open-Source code..!

ARM64 – Odroid C2 – Boots with Kernel 4.10-rc1 – Ethernet OK? – Not yet..

Adventures With Linux ™ Posted on December 26, 2016 by RGJanuary 15, 2017

After applying the aarch64 compile fix (see previous article) I was able to compile Kernel 4.10-rc1 on the Odroid C2, and it boots OK (headless..), and the Ethernet link stays up, but still needs the TX patch..   (updated, as the link did still hang – eventually..  RG).. ……….. meson8b-dwmac c9410000.ethernet eth0: Link is Up – 1Gbps/Full – … Continue reading →

Adventures With Linux ™ Posted on December 26, 2016 by RGDecember 26, 2016

Tried compiling Kernel 4.10-rc1 for aarch64, and got – literally – hundreds of errors: …… ./include/linux/sched.h:3299: Error: unknown mnemonic `return’ — `return test_ti_thread_flag(task_thread_info(tsk),flag)’ ./include/linux/sched.h:3300: Error: junk at end of line, first unrecognized character is `}’ ./include/linux/sched.h:3302: Error: unknown mnemonic `static’ — `static inline void set_tsk_need_resched(struct task_struct*tsk)’ ./include/linux/sched.h:3303: Error: junk at end of line, first unrecognized character is … Continue reading →

KERNEL – 4.10-rc1 Out – OK with VMware, Breaks NVIDIA..

Adventures With Linux ™ Posted on December 26, 2016 by RGDecember 26, 2016

Kernel 4.10-rc1 is out, and brief details are here: http://lkml.iu.edu/hypermail/linux/kernel/1612.3/00220.html Installed it on the test system, and (4.9-patched) VMware 12.5.2 is OK, but the latest NVIDIA driver (375.26) fails to compile: ……………….. /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-375.26/kernel/common/inc/nv-mm.h: In function ‘NV_GET_USER_PAGES_REMOTE’: /home/rgadsdon/kernel/NVIDIA-Linux-x86_64-375.26/kernel/common/inc/nv-mm.h:86:20: error: too few arguments to function ‘get_user_pages_remote’ return get_user_pages_remote(tsk, mm, start, nr_pages, flags, pages, vmas); ^~~~~~~~~~~~~~~~~~~~~ ………………..

ARM64 – Odroid C2 – Latest Ethernet Patch..

Adventures With Linux ™ Posted on December 22, 2016 by RGDecember 22, 2016

After some of the recent ‘Ethernet fix’ patches have not worked with more recent linux-next kernels, I have found one that – at least at the moment – does fix the ‘hang’ problem – again.. The patch is applied to meson-gxbb-odroidc2.dts, and can be found here:  http://archive.arm.linux.org.uk/lurker/message/20161221.113134.3ac4d1e6.en.html I did have to revert this kasir_offset patch (…-R) to … Continue reading →

ARM64 – Odroid C2 – Tested with Linux Net-Next – Ethernet Still Hangs..

Adventures With Linux ™ Posted on December 18, 2016 by RGDecember 18, 2016

Recent versions of the Linux net-next tree could not be tested on the C2, as the meson-gx mmc driver was missing, but now it has been added, and I tested the latest version (December 17) – but the Ethernet hang is still there..      To be fair, this is probably because of the current patch conflict that has … Continue reading →

NVIDIA – New Driver 375.26 – OK with Kernel 4.9..

Adventures With Linux ™ Posted on December 15, 2016 by RGDecember 15, 2016

NVIDIA driver 375.26 has been released, and details are available here:  http://www.nvidia.com/download/driverResults.aspx/112992/en-us I had been experiencing some odd window (KDE5) behaviour with 375.20, and hopefully things might be more stable with this version..     If not, then possibly kwin is to blame..

ARM64 – Odroid C2 – Ethernet Broken Again?

Adventures With Linux ™ Posted on December 12, 2016 by RGDecember 12, 2016

I had been trying to apply the latest round of Meson TX delay patches to the latest linux-next tree, but found that there seems to be a conflict with some of these..    The December 1 patched kernel now has some problems on my C2 with Ethernet traffic, so – for the time being – I have reverted … Continue reading →
