[opensuse-kernel] dwarf2json fails with 5.8.0 kernel from Tumbleweed
by Hans-Peter Jansen 01 Sep '20

01 Sep '20

Hi, slowly approaching volatility3 here. Now, that I learned to build dwarf2json¹ (home:frispete:Tumbleweed/ dwarf2json), I've tried to actually use it. $ zyp in kernel-default-debuginfo $ dwarf2json linux --elf /usr/lib/debug/boot/vmlinux-5.8.0-8-default.debug > 5.8.0-8-default.json Failed linux processing: could not get DWARF from /usr/lib/debug/boot/ vmlinux-5.8.0-8-default.debug: decoding dwarf section info at offset 0x2705: underflow Just generating the symbol map lloks fine: $ dwarf2json linux --system-map /boot/System.map-5.8.0-8-default > 5.8.0-8- default-syms.json Q is, who/what to blame here? Is it our infrastructure, that generates DWARF for the kernel in an unusual way, or is it dwarf2json itself?

[opensuse-kernel] TW: keep selected kernel firmware packages only
by Hans-Peter Jansen 23 Aug '20

23 Aug '20

Hi, after the firmware split, it should be possible to just keep the selected set. On /some/ systems, all FW packages are pulled with a kernel update from zypper dup. Q is, why? $ rpmg ^kernel kernel-default-5.7.11-5.3.x86_64 kernel-default-5.8.0-8.2.x86_64 kernel-default-devel-5.7.11-5.3.x86_64 kernel-default-devel-5.8.0-8.2.x86_64 kernel-devel-5.7.11-5.3.noarch kernel-devel-5.8.0-8.2.noarch kernel-firmware-amdgpu-20200807-1.1.noarch kernel-firmware-bluetooth-20200807-1.1.noarch kernel-firmware-i915-20200807-1.1.noarch kernel-firmware-intel-20200807-1.1.noarch kernel-firmware-media-20200807-1.1.noarch kernel-firmware-network-20200807-1.1.noarch kernel-firmware-nvidia-20200807-1.1.noarch kernel-firmware-platform-20200807-1.1.noarch kernel-firmware-prestera-20200807-1.1.noarch kernel-firmware-radeon-20200807-1.1.noarch kernel-firmware-realtek-20200807-1.1.noarch kernel-firmware-serial-20200807-1.1.noarch kernel-firmware-sound-20200807-1.1.noarch kernel-firmware-usb-network-20200807-1.1.noarch kernel-macros-5.8.0-8.2.noarch $ zyp dup [...] The following 22 NEW packages are going to be installed: kernel-default 5.8.0-8.3 kernel-default-devel 5.8.0-8.3 kernel-firmware-all 20200807-1.1 kernel-firmware-ath10k 20200807-1.1 kernel-firmware-atheros 20200807-1.1 kernel-firmware-bnx2 20200807-1.1 kernel-firmware-brcm 20200807-1.1 kernel-firmware-chelsio 20200807-1.1 kernel-firmware-dpaa2 20200807-1.1 kernel-firmware-iwlwifi 20200807-1.1 kernel-firmware-liquidio 20200807-1.1 kernel-firmware-marvell 20200807-1.1 kernel-firmware-mediatek 20200807-1.1 kernel-firmware-mellanox 20200807-1.1 kernel-firmware-mwifiex 20200807-1.1 kernel-firmware-nfp 20200807-1.1 kernel-firmware-qlogic 20200807-1.1 kernel-firmware-ti 20200807-1.1 kernel-firmware-ueagle 20200807-1.1 [...] kernel 5.8.0-8.* is built in a local OBS.

[opensuse-kernel] Question about kernel-devel
by Larry Finger 06 Aug '20

06 Aug '20

Hi, Now that kernel 5.8.0 has been released, it will likely become the default kernel for Tumbleweed, which means that VirtualBox users will be unable to host VM's on Tumbleweed. As Oracle has not proposed a solution, I am hoping to provide a kernel that exports the two symbols necessary to use VB with kernel 5.8 so that Tumbleweed users do not have to switch to KVM. I branched the kernel-default package under kernel:stable, modified the kernel source with a patch, and have built that modified kernel. I have installed the kernel-default and kernel-default-devel packages from that build and rebooted. My problem is that I also need to generate a corresponding kernel-devel package to get the kernel headers so that external modules can be built. I do not see the means of getting this package. Could someone please point me to documentation that describes the means of getting the headers for this new kernel?
