Option CONFIG_THERMAL_CORE_TESTING
by Jean Delvare 22 Oct '24

22 Oct '24

Hi Michal, I see that you have set CONFIG_THERMAL_CORE_TESTING=m in all kernel config files when updating to 6.12-rc1. I don't think we need this in default kernels, this is clearly a debugging module. Would it be OK with you (and others) if I disable it in the default flavor and only enable it in the debug flavor? Thanks, -- Jean Delvare SUSE L3 Support

Disabling /dev/fb0 on TW
by Thomas Zimmermann 22 Oct '24

22 Oct '24

tl;dr: Disable fbdev userspace interfaces on TW Hi, the upcoming Linux kernel v6.6 will contain the option to disable fbdev userspace interfaces in the kernel configuration. [1] I intent to enable this and thereby switch off /dev/fb0 et al. The tracker bug is boo#1212947. [2] * Why? The old fbdev subsystem is an endless source of bugs. For example, we recently had an out-of-bounds access in the fbdev emulation, where userspace could write beyond the end of the framebuffer memory. [3] Fbdev is under-maintained. I've been doing improvements in recent kernel releases, but only where it benefits the DRM subsystem. Disabling fbdev userspace interfaces will also help weeding out any programs that still contain hard dependencies on them. * What changes? Enabling the new kernel option disables all fbdev userspace interfaces. These are * the device files, such as /dev/fb0 * the sys files under /sys/class/graphics/fb[0-9]+ * /proc/fb * What are the effects on userspace programs? Userspace applications run on the desktop via Wayland or X. There will be no change to them. Xorg and Wayland compositors run on DRM interfaces. A few programs run on SDL, which has no dependency on fbdev either. Any fbdev support in these mid-layer components should be disabled as well. There's one known affected program: TW's text-mode installer can use the tool fbiterm to display CJK symbols during installation. This comes from a time when some low-end systems where not able to boot graphics installation. fbiterm has been unmaintained for >15 years and is ready for retirement. But there's no good drop-in replacement. I propose to simply remove fbiterm and let the graphics installer handle CJK. * What about the framebuffer console? The kernel-provided framebuffer console does not change. The kernel will still show the regular console. Userspace interfaces in /sys/class/graphics/fbcon are still available. For questions and discussion, please comment here or in boo#1212947.

tumbleweed upstream kernel
by S Kosner 15 Oct '24

Hi, It seems tumbleweed does not (normally) use a pure upstream kernel, as kernel-default includes patches. Although, is kernel-vanilla pure upstream like it sounds (albeit maybe compiled with custom options)? Thanks
