From 349bff48ae0f5f8aa2075d0bdc2091a30bd634f6 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 27 Aug 2021 17:53:10 +0300 Subject: [PATCH 1/8] platform/x86/intel: punit_ipc: Drop wrong use of ACPI_PTR() ACPI_PTR() is more harmful than helpful. For example, in this case if CONFIG_ACPI=n, the ID table left unused which is not what we want. Instead of adding ifdeffery here and there, drop ACPI_PTR() and unused acpi.h.

Currently the design in amd-pmc is to try every 100us for up to 20ms. However the GPU driver which also communicates with the SMU using a mailbox register which the driver polls every 1us for up to 2000ms. In the GPU driver this was increased by commit 055162645a40 ("drm/amd/pm: increase time out value when sending msg to SMU") Increase the maximum timeout used by amd-pmc to 2000ms to match this behavior. This has been shown to improve the stability for machines that randomly have failures.
