From 702262d982024e5bab712d3c873c4ac41514ac8c Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Mon, 8 Aug 2022 11:23:07 +0800 Subject: [PATCH] ACPI / table: Print CORE_PIC information when MADT is parsed LoongArch inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5OHOB -------------------------------- When MADT is parsed, print CORE_PIC information as below: ACPI: CORE PIC (processor_id[0x00] core_id[0x00] enabled) ACPI: CORE PIC (processor_id[0x01] core_id[0x01] enabled) ... ACPI: CORE PIC (processor_id[0xff] core_id[0xff] enabled) This debug information will be very helpful to bring up early systems to see if processor_id and core_id are matched or not as spec defined.
