From 8f61d48c83f6e3525a770e44692604595693f787 Mon Sep 17 00:00:00 2001 From: Vishal Verma Date: Thu, 26 Oct 2023 11:32:41 -0600 Subject: [PATCH] tools/testing/cxl: Slow down the mock firmware transfer The cxl-cli unit test for firmware update does operations like starting an asynchronous firmware update, making sure it is in progress, and attempting to cancel it. In some cases, such as with no or minimal dynamic debugging turned on, the firmware update completes too quickly, not allowing the test to have a chance to verify it was in progress. This caused a failure of the signature: expected fw_update_in_progress:true test/cxl-update-firmware.sh: failed at line 88 Fix this by adding a delay (~1.5 - 2 ms) to each firmware transfer request handled by the mocked interface.
