2026-01-20T21:57:02+00:00

STRICT_KERNEL_RWX can not be turned off throught menuconfig on some architectures, pass "rodata=off" to the kernel in this case. Tested with qemu on arm64.

fbcon: Remove fb_debug_enter/_leave from struct fb_ops

2025-12-02T08:20:44+00:00

There are no implementations of fb_debug_enter and fb_debug_leave. Remove the callbacks from struct fb_ops and clean up the caller. The field save_graphics in fbcon_par is also no longer required. Remove it as well. Signed-off-by: Thomas Zimmermann Reviewed-by: Simona Vetter Acked-by: Daniel Thompson (RISCstar) Link: https://patch.msgid.link/20251125130634.1080966-6-tzimmermann@suse.de

Documentation: move dev-tools debugging files to process/debugging/

2024-12-17T20:46:53+00:00

Move gdb and kgdb debugging documentation to the dedicated debugging directory (Documentation/process/debugging/). Adjust the index.rst files to follow the file movement. Adjust files that refer to these moved files to follow the file movement. Update location of kgdb.rst in MAINTAINERS file. Add a link from dev-tools/index to process/debugging/index. Note: translations are not updated.
