Kernel – 6.4-rc Pre-release Testing.. Breaks NVIDIA, VMware OK..

Adventures With Linux ™ Posted on by

Usual caveat..  Not all changes are yet in place, and any code changes are suggestions/hacks only – not a expert recommendation! Testing an interim release (April 29th) of Kernel 6.4-rc, and NVIDIA 530.41.03 fails to compile: LD [M] /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-modeset.o CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm.o CC [M] /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm-drv.o /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm-drv.c: In function ‘nv_drm_update_drm_driver_features’: /home/rgadsdon/NVIDIA-Linux-x86_64-530.41.03/kernel/nvidia-drm/nvidia-drm-drv.c:1439:18: error: ‘struct drm_driver’ has no member named … Continue reading →

Fedora – F38 – ‘Old’ RPMs Gotcha, and Workaround..

Adventures With Linux ™ Posted on by

Testing Fedora 38, and found a problem with some ‘legacy’ RPMs.. Fedora 38 now strictly enforces SHA256 for all RPMs and older/third-party ones still using SHA1 now throw an error: # rpm -q webmin error: rpmdbNextIterator: skipping h# 2316 Header V4 DSA/SHA1 Signature, key ID 11f63c51: BAD Header SHA1 digest: OK package webmin is not installed But…: … Continue reading →

Kernel – GCC 13 Plugins fail – and Fix..

Adventures With Linux ™ Posted on by

Fedora 38 (beta..) has GCC 13, and this causes an error when compiling the kernel with ‘gcc_plugins‘ selected: …………………. CC scripts/mod/devicetable-offsets.s cc1: error: cannot load plugin ./scripts/gcc-plugins/randomize_layout_plugin.so: ./scripts/gcc-plugins/randomize_layout_plugin.so: undefined symbol: tree_code_type make[1]: *** [scripts/Makefile.build:252: scripts/mod/empty.o] Error 1 make[1]: *** Waiting for unfinished jobs…. cc1: error: cannot load plugin ./scripts/gcc-plugins/randomize_layout_plugin.so: ./scripts/gcc-plugins/randomize_layout_plugin.so: undefined symbol: tree_code_type make[1]: *** [scripts/Makefile.build:114: scripts/mod/devicetable-offsets.s] … Continue reading →

Kernel/Boot – Bizarre Dracut problem – Bogus Apple Modules Added, Fails – Cause Found..

During update of the kernel to 6.0.9, on my main dual-xeon Fedora 37 system, I found the following error displayed: ……………………… dracut-install: Failed to find module ‘apple_mailbox’ dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.SGbOUU/initramfs –kerneldir /lib/modules/6.0.9/ -m apple_mailbox nvme_apple pinctrl-apple-gpio macsmc macsmc-rtkit i2c-apple tps6598x apple-dart dwc3 dwc3-of-simple xhci-pci pcie-apple gpio_macsmc spi-apple spi-hid-apple spi-hid-apple-of rtc-macsmc simple-mfd-spmi spmi-apple-controller nvmem_spmi_mfd apple-dockchannel dockchannel-hid … Continue reading →

Kernel – 5.19-rc1 Released. OK With Patched VMware, and a Hack for NVIDIA..

Adventures With Linux ™ Posted on by

Kernel 5.19-rc1 is out, and details are here:  https://lkml.iu.edu/hypermail/linux/kernel/2206.0/04428.html There is a patchset for VMware 16.2.3, at https://github.com/mkubecek/vmware-host-modules/tree/tmp/workstation-16.2.3-k5.19 .   I have tested this with 5.19-rc1, and VMware compiles and loads/runs OK. The latest NVIDIA driver (515.48.07) compile fails, but a hack is to edit NVIDIA-Linux-x86_64-515.48.07/kernel/nvidia-drm/nvidia-dma-resv-helper.h and NVIDIA-Linux-x86_64-515.48.07/kernel/nvidia-drm/nvidia-drm-prime-fence.c and change nv_dma_resv_add_excl_fence to dma_resv_add_excl_fence After this, the driver compiles … Continue reading →

ARM64 – Pi 4 USB Problems – And a Messy Fix..

Adventures With Linux ™ Posted on by

After some delay, I finally had a ‘good’ cooling solution for my 8GB Pi4, and resumed testing.. The last Kernel version I had running on it was 5.9-rc4, and everything seemed to be working OK (including 8GB of memory recognised). I then updated to 5.11.18, and found that none of the USB ports worked: # dmesg |grep … Continue reading →

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

Adventures With Linux ™ Posted on by

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 by

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 by

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 →
