 1.26 Checking kernel for the driver support
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-Some tests may need specific kernel drivers, either compiled in, or built
-as a module. If '.needs_drivers' points to a 'NULL' terminated array of kernel
-module names these are all checked and the test exits with 'TCONF' on the
-first missing driver.
-
-The detection is based on reading 'modules.dep' and 'modules.builtin' files
-generated by kmod. The check is skipped on Android.
+Some tests may need specific kernel drivers, either compiled in, or built as a
+module. For this cases a mappping of kernel config options to modules is
+maintained in the kconfig checker. When a kernel config option is requested by
+a test that has associated mapping in the kconfig source the 'modules.dep' file
+is checked for module presence when the option is set to 'm'. The check is
+skipped on Android.
