From 9b0827f5f068c683e69357fe36258c14fb74cb6b Mon Sep 17 00:00:00 2001 From: bluhm Date: Fri, 4 Oct 2024 16:58:26 +0000 Subject: [PATCH] Increase psp(4) timeouts. On EPYC 9124 psp(4) seems to need more to time to respond. Otherwise it will not attach. Increase timeouts for both polling during autoconf and interrupt during normal operation. from hshoexer@ OK mlarkin@ --- sys/dev/ic/psp.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/sys/dev/ic/psp.c b/sys/dev/ic/psp.c index 5bbbf2de5ee..95babb7d3db 100644 --- a/sys/dev/ic/psp.c +++ b/sys/dev/ic/psp.c @@ -1,4 +1,4 @@ -/* $OpenBSD: psp.c,v 1.4 2024/09/04 08:14:18 jsg Exp $ */ +/* $OpenBSD: psp.c,v 1.5 2024/10/04 16:58:26 bluhm Exp $ */ /* * Copyright (c) 2023, 2024 Hans-Joerg Hoexer @@ -199,7 +199,7 @@ ccp_wait(struct psp_softc *sc, uint32_t *status, int poll) if (poll) { count = 0; - while (count++ < 10) { + while (count++ < 100) { cmdword = bus_space_read_4(sc->sc_iot, sc->sc_ioh, PSP_REG_CMDRESP); if (cmdword & PSP_CMDRESP_RESPONSE) @@ -211,7 +211,7 @@ ccp_wait(struct psp_softc *sc, uint32_t *status, int poll) return (1); } - if (tsleep_nsec(sc, PWAIT, "psp", SEC_TO_NSEC(1)) == EWOULDBLOCK) + if (tsleep_nsec(sc, PWAIT, "psp", SEC_TO_NSEC(2)) == EWOULDBLOCK) return (1); done: -- 2.20.1
