From d5921c460e543228d100daf67dac7a03dfaaa40a Mon Sep 17 00:00:00 2001 From: Hanjun Guo Date: Tue, 10 Oct 2023 16:21:23 +0800 Subject: [PATCH] ACPI: bus: Move acpi_arm_init() to the place of after acpi_ghes_init() acpi_agdi_init() in acpi_arm_init() will register a SDEI event, so it needs the SDEI subsystem to be initialized (which is done in acpi_ghes_init()) before the AGDI driver probing. In commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific initialisation into acpi_arm_init()"), the acpi_agdi_init() was called before acpi_ghes_init() and it causes following failure: | [ 0.515864] sdei: Failed to create event 1073741825: -5 | [ 0.515866] agdi agdi.0: Failed to register for SDEI event 1073741825 | [ 0.515867] agdi: probe of agdi.0 failed with error -5 | ... | [ 0.516022] sdei: SDEIv1.0 (0x0) detected in firmware. Fix it by moving acpi_arm_init() to the place of after acpi_ghes_init().
