ARM64 – Fedora 27, UEFI and Pi3..

I decided – after some time – to do some more with the Raspberry Pi 3, and set it up as a small network print server..

As there was now an ‘official’ version of Fedora 27 for the Pi3, I decided to use this..   Details are here, and links to aarch64 images are near the bottom of the article..   https://fedoraproject.org/wiki/Architectures/ARM/Raspberry_Pi

This version uses u-boot to load EFI, which then boots the Pi3 in the ‘traditional’ way..   After creating the system on the micro-sd card, I ‘saved/restored’ the root filesystem, and modified the partition layout to make it resident on a ‘primary’ partition, rather than ‘extended’, but this was just a personal preference..

Fdisk:
Device       Boot    Start   End       Sectors   Size  Id Type
/dev/mmcblk0p1 *     2048    342015    339968    166M  6  FAT16

/dev/mmcblk0p3 swap      swap defaults 0 0
/dev/mmcblk0p4 /         ext4 defaults 1 1

As I needed to use a serial console, I uncommented  enable_uart=1 in config.txt, and made the appropriate changes to the kernel boot command line..

As usual, the standard Fedora kernel config included many unwanted device selections and options, and so I decided to create a more Pi3-specific one..   A search found some possible candidates, and I tried several of these..

As a result, I found that the Broadcom GPU/DRM driver caused multiple tombstones during the boot process, and killed the HDMI monitor connection:

................     etc... etc...

So, I disabled this ( ‘Broadcom VC4 Graphics‘ ), and just used the framebuffer option..     The device will (obviously) be used ‘headless’, so this is not an issue..

It was a refreshing change to be able to use the x86-standard kernel compile/install commands, and to be able to use grub-customizer to handle boot options etc..   I set up the dtb link in the /boot directory to match the Fedora example..

I did find slightly confusing behaviour with the console options…   I had (temporarily) modified grub.cfg to include the usual console=tty0 console=ttyS0,115200n8, and this worked OK at first boot, but after I had compiled/installed later kernels, and included this in the grub parameters, this stopped working, and there was no output on the serial/uart connection at boot time, after the usual grub menu dialogue..

I then discovered that – for some reason – the ports had changed, and now required console=tty1 console=ttyS1,115200n8. This worked OK for the Fedora-supplied kernels, but not for the self-compiled ones..   I then found that the uart/port selections in the kernel configs I was testing had been – deliberately – disabled, probably due to the fact that these console options cause performance degradation, because of design tradeoffs on the Pi3..

So, I modified the kernel config in the appropriate areas:

Select ‘Console on 8250/16550 serial port
Change ‘Maximum 8250/16550 and compatible serial ports‘  to ‘4
Change ‘Maximum 8250/16550 serial ports to register at runtime‘  to ‘4

After this, all was well:

NVIDIA – Kernel 4.15-rc3 fixes GPL Problem..

Just updated the test system to Kernel 4.15-rc3, and the GPL issue for NVIDIA drivers has been fixed, as mentioned – vaguely – in the brief details here:  http://lkml.iu.edu/hypermail/linux/kernel/1712.1/01379.html.

NVIDIA driver 384.98, with the first 4.15 patch (see http://rglinuxtech.com/?p=2134 ), now compiles and loads OK:

IA64 – Update to Kernel 4.15-rc1..

Just updated the Itanium2 system (RX2600/ZX9000 hybrid) to kernel 4.15-rc1, but encountered a problem with the NFSv4 code.    Recent changes have exposed problems with ‘older’ compilers, and the system currently has GCC 4.3 (on Fedora 9/IA64):

This is a ‘known problem’ and has – at least – been documented:  https://lkml.org/lkml/2017/11/18/224

The workaround – for the time being – is to simply deselect NFSv4 support in the Kernel config, and then the compile completes, and the system boots OK:

I have – so far – successfully swapped out the RX2600 all-PCI-X cage for a ZX9000 PCI-X/AGP one, and installed a NVIDIA Quadro 900 dual-DVI video card, but have not yet managed to get a more ‘modern’ version of Nouveau working, and so am still using framebuffer, and VNC.

NVIDIA – Fix for Kernel 4.15, but GPL Problem – Yet Again..

Thanks to milhouse, there is a set of two patches available for NVIDIA 384.98 and (legacy) 340.104 with Kernel 4.15-rc1, and details are here:   https://devtalk.nvidia.com/default/topic/1026911/linux/4-15-rc1-patches-for-384-98-and-340-104/

The first patch fixes the compile problems, but the load fails with yet another case of GPL incompatibility:

...................
 Building modules, stage 2.
 MODPOST 4 modules
FATAL: modpost: GPL-incompatible module nvidia-drm.ko uses GPL-only symbol 'ex_handler_refcount'

make[1]: *** [Makefile:146: sub-make] Error 2
make[1]: Leaving directory '/usr/src/linux-4.15-rc1'
make: *** [Makefile:81: modules] Error 2

The second patch is technically ‘illegal’, as it changes the licence in ~/kernel/nvidia-drm/nvidia-drm-linux.c from MIT to GPL… but does allow the driver to load successfully..

This GPL problem with NVIDIA seems to occur with monotonous regularity for each new kernel release, now..   If past experience is anything to go by, this will probably be fixed – eventually – by some kindly kernel dev opting to change the licensing requirement back to non-GPL-only..

I have done some digging around, and the change in kernel code would appear to be this mega-patch:  https://github.com/torvalds/linux/commit/b24413180f5600bcb3bb70fbed5cf186b60864bd

Another option, which may not be suitable for many systems – is to compile without drm..

# export NV_EXCLUDE_KERNEL_MODULES=nvidia-drm
# make ......etc..

VMware – Fix for Kernel 4.15-rc1..

Thanks – again – to mkubecek, there is now a fix for VMware 14.0.0 and Kernel 4.15 – and details are here:   https://github.com/mkubecek/vmware-host-modules/commit/562121d7bc06

The fix involves changes to vmmon-only/linux/driver.c and vmmon-only/linux/hostif.c, and a new file: vmmon-only/include/compat_timer.h .    I have tested this on 4.15-rc1, and now vmmon compiles, and vmware loads/runs, correctly.

IA64 – An Exercise in Nostalgia..

Ever since I spent some considerable time promoting HP’s IA64 Linux systems, way back in the early-2000’s, I have always wanted one for myself, and I recently managed to acquire an RX2600 1U server for a very reasonable price, and beef it up with some inexpensive parts from eBay..

The spec – at the moment – is 2x 1.5Ghz ‘Madison’ CPUs, and 8GB memory, and one 74GB U320 disk.. This basic chassis is identical to the one used for the ‘workstation’ version – the Z6000 – and I am planning to do a conversion, to allow better (AGP) graphics..

RX2600 Chassis

I had managed to track down the remaining IA64 versions of various Distros, and the ‘latest’ (2008..) one was Fedora 9, which is still available online, if you are able to do some digging.. I created a DVD install disk, and made a complete copy of the old repo, including all the packages..

This exercise was a good test of my install recollections from 9+ years ago, and was relatively straightforward.. As expected, there were a several things not there – or too ‘new’ – including EXT4 support. I settled on EXT3 for the time being, and this may be OK..

I had been cross-compiling the latest (4.14) kernels on my F27 x86_64 system, as – fortunately – there is still a viable ia64 cross-compiler available..

export ARCH=ia64
export CROSS_COMPILE=ia64-linux-gnu-
 etc...

I also had to (re)remember all the old LILO stuff, as the system uses the EFI version of this – ELILO..

The server has 4 PCI-X slots (not PCI-Express..) and there are still a few i/o cards available for this.. It came with an old NVIDIA Quadro NVS280 card, and I was able to get a dual-hdmi connector ‘tail’ for this..

The install was only possible in ‘non-graphical’ mode, but this worked OK, and it was actually easier to use than the modern bells-and-whistles version.. IMHO..

At the end, I had a working system, running the ancient 2.6.25-14 kernel..

As the latest kernel still has some IA64 activity (although very little..) I decided to try to compile this natively, and get it running… More on this in a later article, but I did manage to get the compile to work, using a kernel config copied from the cross-compile testing, as I was unable to get any of the graphical configurators to work, and did not want to waste too much time..

Although there is some ‘nouveau’ content with FC9, I found that with nouveau configured in the kernel, the system started to boot and then crashed/re-booted, so I took nouveau support out for the time being (just using framebuffer)

Even with an ancient version of GCC (4.3.0) the kernel compile completed successfully, despite several warnings.. and after modifying the EFI and ELILO config a little – I actually got the system to boot:

.....................

 Linux rgia64 4.14.1 #1 SMP Tue Nov 21 06:19:05 PST 2017 ia64 ia64 ia64 GNU/Linux

So far, I have also got webmin to work:

Webmin IA64

That is all the progress to date, and my goal is to get MOCK working, and build an up-to-date Fedora 27 Distro, although this might be a touch too ambitious, as many of the tools to do this were never fully developed, and many projects on IA64 have been ‘abandoned’…

VMware – 12.5.8 Released – Still Incompatible..

There has been a new release of Workstation 12.5 – 12.5.8 – and the – rather vague – release notes are here:  https://docs.vmware.com/en/VMware-Workstation-Pro/12.0/rn/workstation-1258-release-notes.html

I tested this with a ‘clean’ install on my cash-and-burn system, and basically, it suffers from the same compatibility problems as 12.5.7.    GCC7, Fedora 26/27, and Kernel 14.x all cause it to fail.

As I have already migrated to Workstation 14.0.0, I did not do any further testing..    I would speculate that the convoluted workarounds and patches used for 12.5.7 may still work with 12.5.8…     Hopefully there will be a 14.0.1 soon?

After upgrading four Fedora systems (x86_64) from release 26 to 27, using # dnf system-upgrade download --refresh --releasever=27 --allowerasing --nogpgcheck --best -y, two of these worked OK, but two failed – with a sudden reboot, back to F26 – and no (apparent) error displayed, after # dnf system-upgrade reboot had rebooted the system, and the upgrade process had started, but before the actual rpms were processed:

dnf[91reboot: Restarting system
..............   (system reboots, into F26 again..

I had encountered a similar problem before, and was able to work out a – rather convoluted – workaround..

In this upgrade, the F27 rpms are resident at /var/lib/dnf/system-upgrade , and each repo has its own sub-directory – the repo ID followed by a uuid-style numerical string, eg:  fedora-cba4cf65782eccda , updates-09879b494aeba108 , rpmfusion-free-093775106f01a54b etc..    In each of these, the F27 upgrade rpms – if there are any – are in the packages sub-directory..  If there are no upgrade rpms for a particular repo, then the packages sub-directory will not exist..

As root, I created a temporary directory and copied each group of F27 rpms to this, so that the update/upgrade could be done all-at-once..  Then I checked for the kernel….xxx rpms, and installed (not updated!) these by # rpm -ivh kernel*rpm --nodeps --force , and then deleted them..   After that, I updated all the remaining F27 rpms:  # rpm -Uvh *rpm --nodeps --force , and waited for this to complete (which takes some time!).      After that, I simply re-booted the system, and it came back up – correctly – as Fedora 27.

Kernel – 4.14 Released – OK with Latest NVIDIA and – Patched – VMware

Kernel 4.14 is now out, and brief details – including updates from -rc8 – are here:  http://lkml.iu.edu/hypermail/linux/kernel/1711.1/03305.html

As expected, the latest NVIDIA drivers (384.98 and 387.22) are OK with this release, and VMware 14.0.0 – with the vmmon patch ( see http://rglinuxtech.com/?p=2090 ) – is OK as well..
