Kernel – 4.18 Finally Released – OK with latest NVIDIA, and Patched VMware

Posted on August 12, 2018 by RGAugust 12, 2018

Kernel 4.18 has finally arrived, and details of changes since -rc8 are here: http://lkml.iu.edu/hypermail/linux/kernel/1808.1/02806.html

As expected, after changes in -rc7, the latest NVIDIA and (patched) VMware all compile/load OK.. Tested with VMware 14.1.2 with the vmmon patch, and NVIDIA 390.77 and 396.51.

Coincidentally, I can also confirm that 4.18 boots OK on HP PA-RISC (HP9000/785-C3700) – but more on that, in a later article..

PA-RISC – Back to the Future (Again..)

Posted on August 8, 2018 by RGAugust 8, 2018

As part of my quest to test Linux on more obscure/historical hardware, and given that the theme was ‘HP’ after my perilous foray into the world of Linux on IA64, I have now acquired (eBay!) an ‘inexpensive’ PA-RISC system – HP 9000/785 C3700 – after upgrading from an older C3000, and adding some more up-to-date IO cards..

The system shows its age, by only having 10/100 (DEC!) Ethernet built-in, and USB1.1 connectors for just a mouse and keyboard, and has mixed PCI/PCIX card slots – and a floppy drive!. Fortunately, there are inexpensive HP PCIX Gigabit Ethernet cards available, and I installed one of these (NC7771), together with a ‘proper’ USB2 card (Belkin). I also beefed up the memory to 4GB, but this may well have been overkill, as I later discovered…

There are two Distros available for PA-RISC, and after my struggles with Gentoo on the IA64 system, I decided (from over 20 years with Red Hat / Fedora!) on the lesser-of-two-evils, and installed Debian. The ‘standard’ Debian release was quite ancient – with a 3.16 Kernel – but fortunately there is an up-to-date ‘development’ version available, with Kernel 4.17 etc… This may be ‘interesting’ for my IA64 project as well, as it appears that Debian have started to produce a similarly up-to-date version for IA64 as well, after many years!

My goal for this project, as usual, is to be able to use this as another more ‘interesting’ testing platform for the latest kernel versions, for the least expense!

More on my tribulations with the actual Linux installation, and configuration, in a later article…

NVIDIA – GPL Problem with Kernel 4.18, But only for Some.. Fixed in 4.18-rc7.

Posted on August 1, 2018 by RGAugust 1, 2018

Thanks to towo, for pointing out that some others have had GPL issues with the latest NVIDIA drivers and Kernel 4.18-rc6, even though they compiled/loaded OK on my test system, as reported in an earlier article..

See https://devtalk.nvidia.com/default/topic/1037642/linux/driver-390-77-not-compiling-in-kernel-4-18-rc5-xubuntu-18-04/ and other reports..

I changed my usual system-specific kernel config in 4.18-rc6 to the ‘Distro’ (Fedora) version, with almost-everything-selected, and was then able to reproduce the problem:

I have checked on the offending code, in linux-4.18-rc6/kernel/memremap.c, and compared with the same file in 4.18-rc7:

4.18-rc6:
# grep EXPORT_SYMBOL memremap.c
EXPORT_SYMBOL(device_private_entry_fault); EXPORT_SYMBOL(devm_memremap_pages); EXPORT_SYMBOL_GPL(get_dev_pagemap); EXPORT_SYMBOL_GPL(devmap_managed_key); EXPORT_SYMBOL_GPL(dev_pagemap_get_ops); EXPORT_SYMBOL_GPL(dev_pagemap_put_ops); EXPORT_SYMBOL_GPL(__put_devmap_managed_page);

4.18-rc7:

So.. It would appear that the problem has been fixed in 4.18-rc7 (tested with the full ‘Distro’ kernel config):

I should mention that using the full ‘Distro’ kernel config is not ideal for my test system, as it causes a load of ACPI and other errors at boot time, and is only for a ‘generic X86_64’… A better solution – at least for compile-time testing – would probably be to use a VMware Fedora VM..

Kernel 4.18-rc6 has been released, and details of changes since -rc5 are here: http://lkml.iu.edu/hypermail/linux/kernel/1807.2/06572.html

The latest NVIDIA drivers ( 390.77 and 396.45 ) compile/load OK, as does vmmon-patched VMware 14.1.2 (see http://rglinuxtech.com/?p=2322 ).

X86_64 – Fedora Upgrade on Intel ‘Apollo Lake’ System Disables EFI boot – and Fix

Posted on July 15, 2018 by RGJuly 15, 2018

The Intel SOC AP42 system is not supported by Grub2-EFI, but boots using rEFInd (see article at http://rglinuxtech.com/?p=2021 ).

I had hoped to prevent the ‘automatic’ (re)install of grub2-efi etc by masking the (minimal) grub installation of grubby etc. – necessary to support the Kernel # make install function – using # rpm -e --justdb --nodeps <package>. I then found that – for some reason – the rEFInd install was still overwritten during # dnf system-upgrade reboot etc..

Fortunately the re-install of rEFInd on this system was relatively simple. I created a bootable USB stick with the AltLinux Rescue Disk installed – which uses rEFInd (see https://en.altlinux.org/Rescue ), and booted from this. Then all I had to do was run # refind-install --usedefault /dev/mmcblk0p1 to get the boot working again, with my existing rEFInd config. Note that this is different from the usual grub2 install, and the target is the EFI partition itself.

Fedora – F28 Upgrade on ARM64 – Fix for GPG Errors..

Posted on July 6, 2018 by RGJuly 6, 2018

When doing a # dnf system-upgrade reboot on an ARM64 system you may encounter a stream of GPG errors, followed by reboot, without upgrade.

To fix this, simply import the F28 GPG key in advance, as done for Rawhide:

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-28-primary

After this, the system-upgrade should proceed correctly..

Fedora – Fix For Annoying F27 KDE/Dolphin QT Bug..

Posted on June 27, 2018 by RGJune 27, 2018

The latest version of QT5 on Fedora 27 – qt5-qtbase-5.9.6-1.fc27.x86_64 – produces a very annoying display problem in KDE’s Dolphin file manager, where the window does not resize/reformat correctly, leaving large blank areas at each side:

Dolphin window problem..

This has been identified as a QT5 bug/regression, and a patch is available, at https://codereview.qt-project.org/#/c/233482/

I have applied this, and Dolphin now behaves correctly, again. QT5 5.10.1-6 on Fedora 28 does not have this problem, but that update is not – yet – available for Fedora 27.

Kernel – 4.18-rc2 is Out – Includes fix for VMware Runtime, OK with Latest Patched VMware and NVIDIA.

Posted on June 24, 2018 by RGJune 24, 2018

Kernel 4.18-rc2 has been released, and brief details of changes from -rc1 are here: http://lkml.iu.edu/hypermail/linux/kernel/1806.3/00112.html

This includes the cmdline fix, which enables the VMware runtimes to execute correctly. The VMware 14.1.2 vmmon patch is still required (see http://rglinuxtech.com/?p=2322 )

NVIDIA 390.67 compiles OK, with the nvidia-drm-drv.c patch (see http://rglinuxtech.com/?p=2315 )
