Compiler – Fun with CLANG – Kernel, NVIDIA, and VMware…

Adventures With Linux ™ Posted on March 27, 2021 by RGMarch 30, 2021

I have been carrying out some preliminary tests to see how feasible it is to compile the Linux Kernel, and NVIDIA drivers, and VMware, using the ‘alternative’ to GCC – CLANG.. The kernel compile is relatively easy, and well documented: # make CC=clang HOSTCC=clang -j8 (for a 4-core system) The compile seems to be slower than GCC, … Continue reading →

ARM – Vim3-Pro – with EFI and Fedora 33..

Adventures With Linux ™ Posted on January 5, 2021 by RGJanuary 5, 2021

Recently acquired one of the Khadas VIM3-Pro arm64 SoCs, and was impressed with the level of documentation available.. Unfortunately – as is so often the case – this was all relentlessly Ubuntu-focussed, with a semi-proprietary kernel based on the 4.X kernel tree.. At least the U-Boot version was fairly recent, and appeared to support EFI etc.. The … Continue reading →

Fedora – Fun with ZRAM..

Adventures With Linux ™ Posted on September 4, 2020 by RGSeptember 4, 2020

Fedora 33 will be using ZRAM as standard for swap, rather than a partition or swapfile on disk.    I had no problem with this on a new F33 install (Odroid H2Plus) but after upgrading an existing Fedora 32 system it refused to initialise, and ‘/dev/zram0‘ did not exist.    Research revealed that the documentation for much of this … Continue reading →

ARM64 – Fedora 33 Pre-release Kernel Boot Problem – and Workaround..

Adventures With Linux ™ Posted on August 26, 2020 by RGAugust 26, 2020

I have been testing Fedora 33 pre-release, and on x86_64 it seems relatively stable (usual caveats…) but on arm64 systems (Odroid N2 and Pi4) I found that after compiling a new kernel (5.8.3), the system booted, but login was impossible, and screen output was missing  (uart/console was OK). Kernels compiled with Fedora 32 all booted OK, and … Continue reading →

VirtualBox – Latest Development Version Tests with Kernel 5.8 – Unstable..

Adventures With Linux ™ Posted on August 3, 2020 by RGAugust 4, 2020

I have been investigating alternatives, as VMware is currently a non-starter (literally..) with Kernel 5.8.. I installed the latest VirtualBox (6.1.97 r139689) from SVN (another blast from the past…) and managed – after some messing around – to get it to compile OK on my Fedora 32 test system with Kernel 5.8 (from kernel.org..)    I had … Continue reading →

ARM64 – 8GB Pi4 – Fun with Fedora..

Adventures With Linux ™ Posted on July 18, 2020 by RGJuly 18, 2020

My 8GB Raspbery Pi 4 finally arrived, and I was looking forward to trying Fedora 32 and KDE/Plasma on it, and comparing it to the Odroid N2 from a few months back.. ( http://rglinuxtech.com/?p=2689 ) The Fedora 32 aarch64 install is supposed to support the Pi 4 now, but the resulting sdcard image failed to boot, with … Continue reading →

Kernel – 5.8-rc2 – Still Catastrophic Failure with VMware Runtime.

Adventures With Linux ™ Posted on June 22, 2020 by RGJune 22, 2020

Kernel 5.8-rc2 has been released, and brief details are here:  http://lkml.iu.edu/hypermail/linux/kernel/2006.2/08747.html There is no change to the problem with VMware runtime, and vmware-modconfig still segfaults, and the system still reboots immediately, when a VM open is attempted. To check that this was not due to a kernel misconfiguration, I installed the Fedora (Rawhide) version of Kernel 5.8-rc1 … Continue reading →

Kernel – 5.8-rc1 Released – Problem with VMware Runtime..

Adventures With Linux ™ Posted on June 14, 2020 by RGJune 14, 2020

Kernel 5.8-rc1 has been released, and details are here:   http://lkml.iu.edu/hypermail/linux/kernel/2006.1/07293.html NVIDIA 440.82 with the 5.7 and 5.8 patches seems to be OK, but I have encountered a serious problem with VMware, and have now confirmed the same fault on two different systems (both Fedora 32 x86_64) The VMware 15.5.6 vmmon/vmnet modules compile/run OK with the kernel 5.7 … Continue reading →

There is an updated patch for NVIDIA 440-59 with Kernel 5.3, which includes the Y2038 fixes, at https://gitlab.com/snippets/1937313 This compiles with GCC10 now, and I have briefly tested it on my Fedora32 system, with KDE/Plasma and VMware, and it seems to be working OK.

NVIDIA – Extra 440.59 Patch for 5.6-rc3 – With a Gotcha..

Adventures With Linux ™ Posted on February 25, 2020 by RGFebruary 25, 2020

Thanks to Isaak I. Aleksandrov, there is now an additional patch for NVIDIA driver 440.59 to accommodate the Y2038 changes in Kernel 5.6-rc3.   This should be applied after the original 5.6-rc1 patch ( https://gitlab.com/snippets/1937313 ), and can be found here:  https://gitlab.com/snippets/1944237 I have tested this, and it compiles OK with GCC9 (current distros) but fails with GCC10 … Continue reading →
