yeah... so I did a quick and dirty grep:

sed -n "s/.*ENABLED(CONFIG_\([A-Z_0-9]\+\).*/\1/p" -- drivers/gpu/drm/xe/*.[ch] | sort -u
CONFIGFS_FS
DEBUG_FS
DRM_XE_DEBUG
DRM_XE_DEBUG_GUC
DRM_XE_DEBUG_MEM
DRM_XE_DEBUG_SRIOV
DRM_XE_DEBUG_VM
DRM_XE_DISPLAY
DRM_XE_ENABLE_SCHEDTIMEOUT_LIMIT
DRM_XE_GPUSVM
DRM_XE_KUNIT_TEST
DRM_XE_LMTT_2L_128GB
DRM_XE_PAGEMAP
DRM_XE_USERPTR_INVAL_INJECT
I2C
INTEL_MEI_GSC_PROXY
LOCKDEP
PERF_EVENTS
PROVE_LOCKING
TRACE_GPU_MEM
X86

Checking for them:

$ git grep "config $foo\$" -- '**/Kconfig*'

It seems we are also doing something weird with
DRM_XE_LMTT_2L_128GB coming from commit b1d204058218 ("drm/xe/pf:
Introduce Local Memory Translation Table")
