From 7dc924d7c595b21c084644be6d18014aae505b0f Mon Sep 17 00:00:00 2001 From: ChunyouTang Date: Thu, 8 Jul 2021 15:34:06 +0800 Subject: [PATCH] drm/panfrost:fix the exception name always "UNKNOWN" The exception_code in register is only 8 bits,So if fault_status in panfrost_gpu_irq_handler() don't (& 0xFF),it can't get correct exception reason. and it's better to show all of the register value to custom,so it's better fault_status don't (& 0xFF).
