The driver doesn't know how X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=64bdd17f81e3adb02c9168470223c7a495ff0008;p=openbsd Mask off MAC management counter interrupts. The driver doesn't know how to handle these, so if they're enabled, they will cause an interrupt storm. ok patrick@ jsg@ stsp@ --- diff --git a/sys/dev/ic/dwqe.c b/sys/dev/ic/dwqe.c index 0467a4c7247..3e9f6569240 100644 --- a/sys/dev/ic/dwqe.c +++ b/sys/dev/ic/dwqe.c @@ -1,4 +1,4 @@ -/* $OpenBSD: dwqe.c,v 1.18 2024/03/29 08:19:40 stsp Exp $ */ +/* $OpenBSD: dwqe.c,v 1.19 2024/04/25 08:51:37 jmatthew Exp $ */ /* * Copyright (c) 2008, 2019 Mark Kettenis * Copyright (c) 2017, 2022 Patrick Wildt @@ -213,6 +213,8 @@ dwqe_attach(struct dwqe_softc *sc) /* Disable interrupts. */ dwqe_write(sc, GMAC_INT_EN, 0); dwqe_write(sc, GMAC_CHAN_INTR_ENA(0), 0); + dwqe_write(sc, GMAC_MMC_RX_INT_MASK, 0xffffffff); + dwqe_write(sc, GMAC_MMC_TX_INT_MASK, 0xffffffff); return 0; } diff --git a/sys/dev/ic/dwqereg.h b/sys/dev/ic/dwqereg.h index bc6de32a5a5..7f44de46d92 100644 --- a/sys/dev/ic/dwqereg.h +++ b/sys/dev/ic/dwqereg.h @@ -1,4 +1,4 @@ -/* $OpenBSD: dwqereg.h,v 1.5 2023/11/11 16:32:56 stsp Exp $ */ +/* $OpenBSD: dwqereg.h,v 1.6 2024/04/25 08:51:37 jmatthew Exp $ */ /* * Copyright (c) 2008, 2019 Mark Kettenis * Copyright (c) 2017, 2022 Patrick Wildt @@ -83,6 +83,8 @@ #define GMAC_MAC_MDIO_DATA 0x0204 #define GMAC_MAC_ADDR0_HI 0x0300 #define GMAC_MAC_ADDR0_LO 0x0304 +#define GMAC_MMC_RX_INT_MASK 0x070c +#define GMAC_MMC_TX_INT_MASK 0x0710 #define GMAC_MTL_OPERATION_MODE 0x0c00 #define GMAC_MTL_FRPE (1 << 15)
