From 200fbe924466720bd2a8c5eb05b05d67b0a2414c Mon Sep 17 00:00:00 2001 From: Lukas Larsson Date: Thu, 14 Mar 2013 15:42:19 +0100 Subject: Added support for ENEA OSE This port has support for both non-smp and smp. It contains a new way to do io checking in which erts_poll_wait receives the payload of the polled entity. This has implications for all linked-in drivers. --- erts/emulator/sys/common/erl_check_io.c | 115 ++++++++++++++++++++++++++++++-- 1 file changed, 108 insertions(+), 7 deletions(-) (limited to 'erts/emulator/sys/common/erl_check_io.c') diff --git a/erts/emulator/sys/common/erl_check_io.c b/erts/emulator/sys/common/erl_check_io.c index 7035dc77df..dab056e2df 100644 --- a/erts/emulator/sys/common/erl_check_io.c +++ b/erts/emulator/sys/common/erl_check_io.c @@ -34,6 +34,7 @@ #endif #include "sys.h" #include "global.h" +#include "erl_port.h" #include "erl_check_io.h" #include "erl_thr_progress.h" #include "dtrace-wrapper.h" @@ -78,6 +79,12 @@ typedef char EventStateFlags; #define ERTS_CIO_POLL_INIT ERTS_POLL_EXPORT(erts_poll_init) #define ERTS_CIO_POLL_INFO ERTS_POLL_EXPORT(erts_poll_info) +#ifdef __OSE__ +#define GET_FD(fd) fd->id +#else +#define GET_FD(fd) fd +#endif + static struct pollset_info { ErtsPollSet ps; @@ -435,7 +442,11 @@ deselect(ErtsDrvEventState *state, int mode) } } - state->events = ERTS_CIO_POLL_CTL(pollset.ps, state->fd, rm_events, 0, &do_wake); + state->events = ERTS_CIO_POLL_CTL(pollset.ps, state->fd, rm_events, 0, &do_wake +#ifdef __OSE__ + ,NULL +#endif + ); if (!(state->events)) { switch (state->type) { @@ -584,7 +595,11 @@ ERTS_CIO_EXPORT(driver_select)(ErlDrvPort ix, wake_poller = 1; } - new_events = ERTS_CIO_POLL_CTL(pollset.ps, state->fd, ctl_events, on, &wake_poller); + new_events = ERTS_CIO_POLL_CTL(pollset.ps, state->fd, ctl_events, on, &wake_poller +#ifdef __OSE__ + ,prt->drv_ptr->resolve_signal +#endif + ); if (new_events & (ERTS_POLL_EV_ERR|ERTS_POLL_EV_NVAL)) { if (state->type == ERTS_EV_TYPE_DRV_SEL && !state->events) { @@ -894,7 +909,7 @@ print_driver_name(erts_dsprintf_buf_t *dsbufp, Eterm id) static void steal(erts_dsprintf_buf_t *dsbufp, ErtsDrvEventState *state, int mode) { - erts_dsprintf(dsbufp, "stealing control of fd=%d from ", (int) state->fd); + erts_dsprintf(dsbufp, "stealing control of fd=%d from ", (int) GET_FD(state->fd)); switch (state->type) { case ERTS_EV_TYPE_DRV_SEL: { int deselect_mode = 0; @@ -918,7 +933,7 @@ steal(erts_dsprintf_buf_t *dsbufp, ErtsDrvEventState *state, int mode) if (deselect_mode) deselect(state, deselect_mode); else { - erts_dsprintf(dsbufp, "no one", (int) state->fd); + erts_dsprintf(dsbufp, "no one", (int) GET_FD(state->fd)); ASSERT(0); } erts_dsprintf(dsbufp, "\n"); @@ -946,7 +961,7 @@ steal(erts_dsprintf_buf_t *dsbufp, ErtsDrvEventState *state, int mode) break; } default: - erts_dsprintf(dsbufp, "no one\n", (int) state->fd); + erts_dsprintf(dsbufp, "no one\n", (int) GET_FD(state->fd)); ASSERT(0); } } @@ -957,14 +972,21 @@ print_select_op(erts_dsprintf_buf_t *dsbufp, { Port *pp = erts_drvport2port(ix); erts_dsprintf(dsbufp, +#ifdef __OSE__ + "driver_select(%p, %d,%s%s%s%s | %d, %d) " +#else "driver_select(%p, %d,%s%s%s%s, %d) " +#endif "by ", ix, - (int) fd, + (int) GET_FD(fd), mode & ERL_DRV_READ ?
