From 5f246e890502fed387e0f959e2224ea680c03423 Mon Sep 17 00:00:00 2001 From: Andrei Emeltchenko Date: Mon, 11 Jun 2012 11:13:07 +0300 Subject: Bluetooth: Update HCI timeouts constants to use msecs_to_jiffies The HCI constants are always used in form of jiffies. So just include the conversion from msecs in the define itself. This has the advantage of making the code where the timeout is used more readable and avoiding unnecessary conversions. The patch is similar to commit ba13ccd9 doing the same job for L2CAP Reported-by: Marcel Holtmann Signed-off-by: Andrei Emeltchenko Signed-off-by: Gustavo Padovan diff --git a/include/net/bluetooth/hci.h b/include/net/bluetooth/hci.h index 2a6b0b8..7dcd349 100644 --- a/include/net/bluetooth/hci.h +++ b/include/net/bluetooth/hci.h @@ -139,11 +139,11 @@ enum { #define HCIINQUIRY _IOR('H', 240, int) /* HCI timeouts */ -#define HCI_DISCONN_TIMEOUT (2000) /* 2 seconds */ -#define HCI_PAIRING_TIMEOUT (60000) /* 60 seconds */ -#define HCI_INIT_TIMEOUT (10000) /* 10 seconds */ -#define HCI_CMD_TIMEOUT (1000) /* 1 seconds */ -#define HCI_ACL_TX_TIMEOUT (45000) /* 45 seconds */ +#define HCI_DISCONN_TIMEOUT msecs_to_jiffies(2000) /* 2 seconds */ +#define HCI_PAIRING_TIMEOUT msecs_to_jiffies(60000) /* 60 seconds */ +#define HCI_INIT_TIMEOUT msecs_to_jiffies(10000) /* 10 seconds */ +#define HCI_CMD_TIMEOUT msecs_to_jiffies(1000) /* 1 seconds */ +#define HCI_ACL_TX_TIMEOUT msecs_to_jiffies(45000) /* 45 seconds */ /* HCI data types */ #define HCI_COMMAND_PKT 0x01 diff --git a/include/net/bluetooth/hci_core.h b/include/net/bluetooth/hci_core.h index 20fd573..75766b7 100644 --- a/include/net/bluetooth/hci_core.h +++ b/include/net/bluetooth/hci_core.h @@ -598,7 +598,7 @@ static inline void hci_conn_put(struct hci_conn *conn) if (conn->type == ACL_LINK || conn->type == LE_LINK) { del_timer(&conn->idle_timer); if (conn->state == BT_CONNECTED) { - timeo = msecs_to_jiffies(conn->disc_timeout); + timeo = conn->disc_timeout; if (!conn->out) timeo *= 2; } else { diff --git a/net/bluetooth/hci_core.c b/net/bluetooth/hci_core.c index 471e4fb..e91bf7e 100644 --- a/net/bluetooth/hci_core.c +++ b/net/bluetooth/hci_core.c @@ -690,12 +690,11 @@ int hci_dev_open(__u16 dev) set_bit(HCI_INIT, &hdev->flags); hdev->init_last_cmd = 0; - ret = __hci_request(hdev, hci_init_req, 0, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + ret = __hci_request(hdev, hci_init_req, 0, HCI_INIT_TIMEOUT); if (lmp_host_le_capable(hdev)) ret = __hci_request(hdev, hci_le_init_req, 0, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + HCI_INIT_TIMEOUT); clear_bit(HCI_INIT, &hdev->flags); } @@ -782,8 +781,7 @@ static int hci_dev_do_close(struct hci_dev *hdev) if (!test_bit(HCI_RAW, &hdev->flags) && test_bit(HCI_QUIRK_RESET_ON_CLOSE, &hdev->quirks)) { set_bit(HCI_INIT, &hdev->flags); - __hci_request(hdev, hci_reset_req, 0, - msecs_to_jiffies(HCI_CMD_TIMEOUT)); + __hci_request(hdev, hci_reset_req, 0, HCI_CMD_TIMEOUT); clear_bit(HCI_INIT, &hdev->flags); } @@ -872,8 +870,7 @@ int hci_dev_reset(__u16 dev) hdev->acl_cnt = 0; hdev->sco_cnt = 0; hdev->le_cnt = 0; if (!test_bit(HCI_RAW, &hdev->flags)) - ret = __hci_request(hdev, hci_reset_req, 0, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + ret = __hci_request(hdev, hci_reset_req, 0, HCI_INIT_TIMEOUT); done: hci_req_unlock(hdev); @@ -913,7 +910,7 @@ int hci_dev_cmd(unsigned int cmd, void __user *arg) switch (cmd) { case HCISETAUTH: err = hci_request(hdev, hci_auth_req, dr.dev_opt, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + HCI_INIT_TIMEOUT); break; case HCISETENCRYPT: @@ -925,23 +922,23 @@ int hci_dev_cmd(unsigned int cmd, void __user *arg) if (!test_bit(HCI_AUTH, &hdev->flags)) { /* Auth must be enabled first */ err = hci_request(hdev, hci_auth_req, dr.dev_opt, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + HCI_INIT_TIMEOUT); if (err) break; } err = hci_request(hdev, hci_encrypt_req, dr.dev_opt, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + HCI_INIT_TIMEOUT); break; case HCISETSCAN: err = hci_request(hdev, hci_scan_req, dr.dev_opt, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + HCI_INIT_TIMEOUT); break; case HCISETLINKPOL: err = hci_request(hdev, hci_linkpol_req, dr.dev_opt, - msecs_to_jiffies(HCI_INIT_TIMEOUT)); + HCI_INIT_TIMEOUT); break; case HCISETLINKMODE: @@ -2455,7 +2452,7 @@ static void __check_timeout(struct hci_dev *hdev, unsigned int cnt) /* ACL tx timeout must be longer than maximum * link supervision timeout (40.9 seconds) */ if (!cnt && time_after(jiffies, hdev->acl_last_tx + - msecs_to_jiffies(HCI_ACL_TX_TIMEOUT))) + HCI_ACL_TX_TIMEOUT)) hci_link_tx_to(hdev, ACL_LINK); } } @@ -2839,7 +2836,7 @@ static void hci_cmd_work(struct work_struct *work) del_timer(&hdev->cmd_timer); else mod_timer(&hdev->cmd_timer, - jiffies + msecs_to_jiffies(HCI_CMD_TIMEOUT)); + jiffies + HCI_CMD_TIMEOUT); } else { skb_queue_head(&hdev->cmd_q, skb); queue_work(hdev->workqueue, &hdev->cmd_work); -- cgit v0.10.2
