The fault injection code was scattered: the GT reset hook lived in xe_gt.h as an inline function with its own global variable, the CSC hook had a separate global in xe_hw_error.c with an extern declaration, and each was individually registered in xe_debugfs.c. Adding a new error type meant editing many files and copy-pasting the same boilerplate. Debugfs interface (under /sys/kernel/debug/dri/0/): - fail_gt_reset - GT reset failure - inject_csc_hw_error - CSC firmware error Signed-off-by: Mallesh Koujalagi <[email protected]> Reviewed-by: Riana Tauro <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Riana Tauro <[email protected]>
