From a39fbaf23a4a6632bcc17d41481238e8179f8524 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Sun, 20 Feb 2022 16:25:43 +0100 Subject: [PATCH] realtek: use higher priority for timer interrupts The assigned output index for the event timers was quite low, lower even than the ethernet interrupt. This means that high network load could preempt timer interrupts, possibly leading to all sorts of strange behaviour. Increase the interrupt output index of the event timers to 5, which is the highest priority output and corresponds to the (otherwise unused) MIPS CPU timer interrupt.
