X86_64 – UP Board – ‘Cherry Trail’ – Sound – Working..

Adventures With Linux ™ Posted on by

The only missing OS component on the new UP Board (x5-Z8350) was that sound (HDMI) was not present..    After a bit of digging, I found some patches for Kernel 4.5, and a later patched kernel version that was supposed to work.. I tried the patched version of 4.7.0 from here:  https://github.com/plbossart/sound/tree/byt-cht-hdmi-v4.7  but found that the compile failed: … Continue reading →

NVIDIA have released their latest driver – 370.23 – which (finally!) works with Kernel 4.7, without any patches..

X86_64 – Up Board – New Pi-Sized System, with Intel Atom SoC..

Adventures With Linux ™ Posted on by

Just taken delivery of the Up Board – an Intel Atom powered SoC system, with the same form factor as a Pi.. It was quite a novelty to be able to plug a Fedora 24 Live USB stick in, and install directly to the device..      I booted the Live system first, and then used the ‘install to … Continue reading →

Adventures With Linux ™ Posted on by

Kernel 4.8-rc1 is out, and brief details are here:   http://lkml.iu.edu/hypermail/linux/kernel/1608.0/04804.html VMware 12.1.1 – with the previous 4.6/4.7 patches, fails to compile vmmon: /tmp/modconfig-gfkQLR/vmmon-only/linux/hostif.c: In function ‘HostIF_EstimateLockedPageLimit’: /tmp/modconfig-gfkQLR/vmmon-only/linux/hostif.c:1597:47: error: ‘NR_ANON_PAGES’ undeclared (first use in this function) Further research revealed that NR_ANON_PAGES has been changed to NR_ANON_MAPPED in 4.8, and so the fix is quite simple.. In ~/vmmon-only/linux/hostif.c, around … Continue reading →
