Subject: [BUG] mtk-t7xx driver on aarch64/cortex-a53
Date: Fri, 22 Mar 2024 09:06:57 +0100 [thread overview]
Message-ID: <vglpeczsxljzntxhyjew@hpkd> (raw)
Hi
We are facing possible bug in the driver mtk-t7xx under OpenWrt linux 6.1/6.6.
From first glance it looks like the driver is accessing an address in the PCIe MMIO range in 32-bit alignment (ffffffc084a1d004)
but likely the SoC only supports 64-bit aligned (so only addresses ending on 0 or 8 will work) access there,
hence the [ 294.051349] FSC = 0x21: alignment fault.
