From f45d63c1218636f77b9c3c53318c56ecd27dc8ec Mon Sep 17 00:00:00 2001 From: Luis Chamberlain Date: Mon, 19 Dec 2022 11:50:50 -0800 Subject: [PATCH] tools/testing/cxl: require 64-bit size_t is limited to 32-bits and so the gen_pool_alloc() using the size of SZ_64G would map to 0, triggering a low allocation which is not expected. Force the dependency on 64-bit for cxl_test as that is what it was designed for. This issue was found by build test reports when converting this driver as a proper upstream driver.
