new b3d9d96bf testing/ostest: Check the interrupt stack of each CPU.
b3d9d96bf is described below
commit b3d9d96bffab084de8f512e59abf2cc935124330
Author: Marco Casaroli <[email protected]>
AuthorDate: Thu Nov 5 20:21:58 2026 +0100
testing/ostest: Check the interrupt stack of each CPU.
With CONFIG_STACK_COLORATION, each CPU takes an interrupt, then
up_check_intstack() must show some use and some color left. A CPU whose
stack was never colored reports that all of it is used.
