From 1bd9922fa9d1318e4fd1c88a7bd42b8801129255 Mon Sep 17 00:00:00 2001 From: Taylor R Campbell Date: Thu, 31 Mar 2022 02:04:35 +0000 Subject: [PATCH 21/49] alpha: Convert cpu_iccb_send from membar_exit to membar_release. XXX Maybe this should really use alpha_mb, since it's not writing to normal MI-type memory so technically the membr_* semantics doesn't apply? --- sys/arch/alpha/alpha/cpu.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sys/arch/alpha/alpha/cpu.c b/sys/arch/alpha/alpha/cpu.c index 1eaa3a768f43..18fce4d6915a 100644 --- a/sys/arch/alpha/alpha/cpu.c +++ b/sys/arch/alpha/alpha/cpu.c @@ -887,7 +887,7 @@ cpu_iccb_send(long cpu_id, const char *msg) */ strcpy(pcsp->pcs_iccb.iccb_rxbuf, msg); pcsp->pcs_iccb.iccb_rxlen = strlen(msg); - membar_exit(); + membar_release(); atomic_or_ulong(&hwrpb->rpb_rxrdy, cpumask); /* Wait for the message to be received. */
