From 0adea120cdff5c68876d5d8d7152cb90cf4934b1 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Tue, 15 Aug 2017 11:05:30 -0400 Subject: pru: Compile the irq_poll() function with -O2 optimization Compile the PRU binary with -Os optimization, but request that the timer dispatch code be compiled with -O2 optimization. This improves the performance of timers slightly.
