From b25019649c73794eeefae1f2ac382ead9d51ebff Mon Sep 17 00:00:00 2001 From: rwatson Date: Thu, 19 Feb 2009 00:06:01 +0000 Subject: if_cx is currently disconnected from the build due to a dependence on the old TTY implementation; however, take a cut at stripping its optional Giant-protected code paths enabled using debug.cx.mpsafenet, which will no longer work once IFF_NEEDSGIANT is removed. --- sys/dev/cx/if_cx.c | 42 ++++++++++-------------------------------- 1 file changed, 10 insertions(+), 32 deletions(-) (limited to 'sys/dev/cx') diff --git a/sys/dev/cx/if_cx.c b/sys/dev/cx/if_cx.c index be164bd..ad05167 100644 --- a/sys/dev/cx/if_cx.c +++ b/sys/dev/cx/if_cx.c @@ -83,24 +83,9 @@ __FBSDID("$FreeBSD$"); #define CX_LOCK_NAME "cxX" -static int cx_mpsafenet = 1; -TUNABLE_INT("debug.cx.mpsafenet", &cx_mpsafenet); -SYSCTL_NODE(_debug, OID_AUTO, cx, CTLFLAG_RD, 0, "Cronyx Sigma Adapters"); -SYSCTL_INT(_debug_cx, OID_AUTO, mpsafenet, CTLFLAG_RD, &cx_mpsafenet, 0, - "Enable/disable MPSAFE network support for Cronyx Sigma Adapters"); - -#define CX_LOCK(_bd) do { \ - if (cx_mpsafenet) \ - mtx_lock (&(_bd)->cx_mtx); \ - } while (0) -#define CX_UNLOCK(_bd) do { \ - if (cx_mpsafenet) \ - mtx_unlock (&(_bd)->cx_mtx); \ - } while (0) -#define CX_LOCK_ASSERT(_bd) do { \ - if (cx_mpsafenet) \ - mtx_assert (&(_bd)->cx_mtx, MA_OWNED); \ - } while (0) +#define CX_LOCK(_bd) mtx_lock (&(_bd)->cx_mtx) +#define CX_UNLOCK(_bd) mtx_unlock (&(_bd)->cx_mtx) +#define CX_LOCK_ASSERT(_bd) mtx_assert (&(_bd)->cx_mtx, MA_OWNED) typedef struct _async_q { int beg; @@ -239,7 +224,7 @@ static struct cdevsw cx_cdevsw = { .d_close = cx_close, .d_ioctl = cx_ioctl, .d_name = "cx", - .d_flags = D_TTY | D_NEEDGIANT, + .d_flags = D_TTY, }; static int MY_SOFT_INTR; @@ -776,10 +761,10 @@ static int cx_attach (device_t dev) return ENXIO; } b->sys = bd; - callout_init (&led_timo[b->num], cx_mpsafenet ?
