From 89d99141c9b38170e9d466a3db80e4c79664f34e Mon Sep 17 00:00:00 2001 From: kettenis Date: Fri, 11 Oct 2024 09:55:24 +0000 Subject: [PATCH] Revert ehci(4) bits in the previous commit. Apparently 64-bit DMA is broken in (almost?) all ehci(4) controllers. --- sys/dev/usb/ehci.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/sys/dev/usb/ehci.c b/sys/dev/usb/ehci.c index d1a69b662d1..1e8a1368534 100644 --- a/sys/dev/usb/ehci.c +++ b/sys/dev/usb/ehci.c @@ -1,4 +1,4 @@ -/* $OpenBSD: ehci.c,v 1.221 2024/10/08 19:42:31 kettenis Exp $ */ +/* $OpenBSD: ehci.c,v 1.222 2024/10/11 09:55:24 kettenis Exp $ */ /* $NetBSD: ehci.c,v 1.66 2004/06/30 03:11:56 mycroft Exp $ */ /* @@ -317,7 +317,6 @@ ehci_init(struct ehci_softc *sc) sc->sc_noport = EHCI_HCS_N_PORTS(sparams); cparams = EREAD4(sc, EHCI_HCCPARAMS); DPRINTF(("ehci_init: cparams=0x%x\n", cparams)); - sc->sc_bus.dmaflags = EHCI_HCC_64BIT(cparams) ?
