From ec105cadff5d8c0a029a3dc1084cae46cf3f799d Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Sun, 30 Mar 2025 16:31:09 +0800 Subject: [PATCH] LoongArch: Increase MAX_IO_PICS up to 8 Begin with Loongson-3C6000, the number of PCI host can be as many as 8 for multi-chip machines, and this number should be the same for I/O interrupt controllers. To support these machines we also increase the MAX_IO_PICS up to 8.
