From 9c93f8f4fc8cd938bc0ee8d121809c6941e03347 Mon Sep 17 00:00:00 2001 From: Sanket Goswami Date: Tue, 21 Sep 2021 17:29:10 +0530 Subject: [PATCH] platform/x86: amd-pmc: Send command to dump data after clearing OS_HINT It was reported that the resume stats received from the firmware are always zero. This happens because the SMU expects the driver to send the command to dump the log data after clearing the OS_HINT. Adjust the order of the commands sent to SMU.
