ACPI: PRM: Remove unnecessary strict handler address checks

2025-02-05T20:16:40Z

Commit 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM handler and context") added unnecessary strict handler address checks, causing the PRM module to fail in translating memory error addresses. Both static data buffer address and ACPI parameter buffer address may be NULL if they are not needed, as described in section 4.1.2 PRM Handler Information Structure of Platform Runtime Mechanism specification [1]. Here are two examples from real hardware: ----PRMT.dsl---- - staic data address is not used [10Ch 0268 2] Revision : 0000 [10Eh 0270 2] Length : 002C [110h 0272 16] Handler GUID : F6A58D47-E04F-4F5A-86B8-2A50D4AA109B [120h 0288 8] Handler address : 0000000065CE51F4 [128h 0296 8] Satic Data Address : 0000000000000000 [130h 0304 8] ACPI Parameter Address : 000000006522A718 - ACPI parameter address is not used [1B0h 0432 2] Revision : 0000 [1B2h 0434 2] Length : 002C [1B4h 0436 16] Handler GUID : 657E8AE6-A8FC-4877-BB28-42E7DE1899A5 [1C4h 0452 8] Handler address : 0000000065C567C8 [1CCh 0460 8] Satic Data Address : 000000006113FB98 [1D4h 0468 8] ACPI Parameter Address : 0000000000000000 Fixes: 088984c8d54c ("ACPI: PRM: Find EFI_MEMORY_RUNTIME block for PRM handler and context") Reported-and-tested-by: Shi Liu Cc: All applicable Signed-off-by: Aubrey Li Link: https://uefi.org/sites/default/files/resources/Platform%20Runtime%20Mechanism%20-%20with%20legal%20notice.pdf # [1] Reviewed-by: Koba Ko Acked-by: Ard Biesheuvel Link: https://patch.msgid.link/20250126022250.3014210-1-aubrey.li@linux.intel.com [ rjw: Minor changelog edits ] Signed-off-by: Rafael J.

ACPI: resource: IRQ override for Eluktronics MECH-17

2025-02-05T20:12:46Z

The Eluktronics MECH-17 (GM7RG7N) needs IRQ overriding for the keyboard to work. Adding a DMI_MATCH entry for this laptop model makes the internal keyboard function normally.

ACPI: property: Fix return value for nval == 0 in acpi_data_prop_read()

2025-02-05T20:09:28Z

While analysing code for software and OF node for the corner case when caller asks to read zero items in the supposed to be an array of values I found that ACPI behaves differently to what OF does, i.e. 1. It returns -EINVAL when caller asks to read zero items from integer array, while OF returns 0, if no other errors happened. 2. It returns -EINVAL when caller asks to read zero items from string array, while OF returns -ENODATA, if no other errors happened. Amend ACPI implementation to follow what OF does.
