From b2f82565f2caa1a5c1a26e68593eaef355fae3f4 Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Wed, 20 Jun 2018 16:35:16 -0300 Subject: [PATCH] powerpc: Wire up io_pgetevents Wire up io_pgetevents system call on powerpc. io_pgetevents is a new syscall to read asynchronous I/O events from the completion queue. Tested with libaio branch aio-poll[1] and the io_pgetevents test (#22) passed on both ppc64 LE and BE modes.
