From 2d1e82f1224f3109481bb0ed3683e54b09b978e3 Mon Sep 17 00:00:00 2001 From: Max Zhen Date: Tue, 14 Apr 2026 09:56:24 -0700 Subject: [PATCH] accel/amdxdna: Fix fatal_error_info layout in firmware interface Adjust struct fatal_error_info to match the expected driver/firmware interface layout. The structure is used to retrieve debug information from firmware when a command becomes stuck on the device. The reserved field currently uses 128 u32 entries, which makes the structure larger than intended and causes the layout to no longer match the firmware definition. Reduce the reserved array size from 128 to 127 entries so the structure matches the expected interface format.
