From 49f3bdbba8071f56d950a9498b6cdb998b35340a Mon Sep 17 00:00:00 2001 From: Bartlomiej Sieka Date: Wed, 1 Oct 2008 15:26:28 +0200 Subject: net: express the first argument to NetSetTimeout() in milliseconds Enforce millisecond semantics of the first argument to NetSetTimeout() -- the change is transparent for well-behaving boards (CFG_HZ == 1000 and get_timer() countiing in milliseconds). Rationale for this patch is to enable millisecond granularity for network-related timeouts, which is needed for the upcoming automatic software update feature. Summary of changes: - do not scale the first argument to NetSetTimeout() by CFG_HZ - change timeout values used in the networking code to milliseconds Signed-off-by: Rafal Czubak Signed-off-by: Bartlomiej Sieka Signed-off-by: Ben Warren --- net/bootp.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) (limited to 'net/bootp.c') diff --git a/net/bootp.c b/net/bootp.c index 64552ac..c2078c6 100644 --- a/net/bootp.c +++ b/net/bootp.c @@ -33,7 +33,7 @@ #if defined(CONFIG_CMD_NET) -#define TIMEOUT 5UL /* Seconds before trying BOOTP again */ +#define TIMEOUT 5000UL /* Milliseconds before trying BOOTP again */ #ifndef CONFIG_NET_RETRY_COUNT # define TIMEOUT_COUNT 5 /* # of timeouts before giving up */ #else @@ -371,7 +371,7 @@ BootpTimeout(void) puts ("\nRetry count exceeded; starting again\n"); NetStartAgain (); } else { - NetSetTimeout (TIMEOUT * CFG_HZ, BootpTimeout); + NetSetTimeout (TIMEOUT, BootpTimeout); BootpRequest (); } } @@ -671,7 +671,7 @@ BootpRequest (void) bp->bp_htype = HWT_ETHER; bp->bp_hlen = HWL_ETHER; bp->bp_hops = 0; - bp->bp_secs = htons(get_timer(0) / CFG_HZ); + bp->bp_secs = htons(get_timer(0) / 1000); NetWriteIP(&bp->bp_ciaddr, 0); NetWriteIP(&bp->bp_yiaddr, 0); NetWriteIP(&bp->bp_siaddr, 0); @@ -688,7 +688,7 @@ BootpRequest (void) /* * Bootp ID is the lower 4 bytes of our ethernet address - * plus the current time in HZ. + * plus the current time in ms. */ BootpID = ((ulong)NetOurEther[2] << 24) | ((ulong)NetOurEther[3] << 16) @@ -705,7 +705,7 @@ BootpRequest (void) pktlen = BOOTP_SIZE - sizeof(bp->bp_vend) + ext_len; iplen = BOOTP_HDR_SIZE - sizeof(bp->bp_vend) + ext_len; NetSetIP(iphdr, 0xFFFFFFFFL, PORT_BOOTPS, PORT_BOOTPC, iplen); - NetSetTimeout(SELECT_TIMEOUT * CFG_HZ, BootpTimeout); + NetSetTimeout(SELECT_TIMEOUT, BootpTimeout); #if defined(CONFIG_CMD_DHCP) dhcp_state = SELECTING; @@ -849,7 +849,7 @@ static void DhcpSendRequestPkt(Bootp_t *bp_offer) bp->bp_htype = HWT_ETHER; bp->bp_hlen = HWL_ETHER; bp->bp_hops = 0; - bp->bp_secs = htons(get_timer(0) / CFG_HZ); + bp->bp_secs = htons(get_timer(0) / 1000); /* Do not set the client IP, your IP, or server IP yet, since it hasn't been ACK'ed by * the server yet */ @@ -924,7 +924,7 @@ DhcpHandler(uchar * pkt, unsigned dest, unsigned src, unsigned len) if (NetReadLong((ulong*)&bp->bp_vend[0]) == htonl(BOOTP_VENDOR_MAGIC)) DhcpOptionsProcess((u8 *)&bp->bp_vend[4], bp); - NetSetTimeout(TIMEOUT * CFG_HZ, BootpTimeout); + NetSetTimeout(TIMEOUT, BootpTimeout); DhcpSendRequestPkt(bp); #ifdef CFG_BOOTFILE_PREFIX } -- cgit v1.1
