Thanks! * 0.99a: added external trigger. * 1.00: added firmware kernel request to the driver which fixed * udev coldplug problem */ #include <linux/kernel.h> #include <linux/module.h> #include <linux/slab.h> #include <linux/input.h> #include <linux/fcntl.h> #include <linux/compiler.h> #include <linux/comedi/comedi_usb.h> /* * timeout for the USB-transfer */ #define EZTIMEOUT 30 /* * constants for "firmware" upload and download */ #define FIRMWARE "usbduxfast_firmware.bin" #define FIRMWARE_MAX_LEN 0x2000 #define USBDUXFASTSUB_FIRMWARE 0xA0 #define VENDOR_DIR_IN 0xC0 #define VENDOR_DIR_OUT 0x40 /* * internal addresses of the 8051 processor */ #define USBDUXFASTSUB_CPUCS 0xE600 /* * max length of the transfer-buffer for software upload */ #define TB_LEN 0x2000 /* * input endpoint number */ #define BULKINEP 6 /* * endpoint for the A/D channellist: bulk OUT */ #define CHANNELLISTEP 4 /* * number of channels */ #define NUMCHANNELS 32 /* * size of the waveform descriptor */ #define WAVESIZE 0x20 /* * size of one A/D value */ #define SIZEADIN (sizeof(s16)) /* * size of the input-buffer IN BYTES */ #define SIZEINBUF 512 /* * 16 bytes */ #define SIZEINSNBUF 512 /* * size of the buffer for the dux commands in bytes */ #define SIZEOFDUXBUF 256 /* * number of in-URBs which receive the data: min=5 */ #define NUMOFINBUFFERSHIGH 10 /* * min delay steps for more than one channel * basically when the mux gives up ;-) * * steps at 30MHz in the FX2 */ #define MIN_SAMPLING_PERIOD 9 /* * max number of 1/30MHz delay steps */ #define MAX_SAMPLING_PERIOD 500 /* * number of received packets to ignore before we start handing data * over to comedi, it's quad buffering and we have to ignore 4 packets */ #define PACKETS_TO_IGNORE 4 /* * comedi constants */ static const struct comedi_lrange range_usbduxfast_ai_range = { 2, { BIP_RANGE(0.75), BIP_RANGE(0.5) } };

sta_info) are managed in a hash table * for faster lookup and a list for iteration. They are managed using * RCU, i.e. access to the list and hash table is protected by RCU. * * Upon allocating a STA info structure with sta_info_alloc(), the caller * owns that structure. It must then insert it into the hash table using * either sta_info_insert() or sta_info_insert_rcu(); only in the latter * case (which acquires an rcu read section but must not be called from * within one) will the pointer still be valid after the call. Note that * the caller may not do much with the STA info before inserting it; in * particular, it may not start any mesh peer link management or add * encryption keys. * * When the insertion fails (sta_info_insert()) returns non-zero), the * structure will have been freed by sta_info_insert()! * * Station entries are added by mac80211 when you establish a link with a * peer. This means different things for the different type of interfaces * we support. For a regular station this mean we add the AP sta when we * receive an association response from the AP. For IBSS this occurs when * get to know about a peer on the same IBSS. For WDS we add the sta for * the peer immediately upon device open. When using AP mode we add stations * for each respective station upon request from userspace through nl80211. * * In order to remove a STA info structure, various sta_info_destroy_*() * calls are available. * * There is no concept of ownership on a STA entry; each structure is * owned by the global hash table/list until it is removed. All users of * the structure need to be RCU protected so that the structure won't be * freed before they are done using it. */ struct sta_link_alloc { struct link_sta_info info; struct ieee80211_link_sta sta; struct rcu_head rcu_head; }; static const struct rhashtable_params sta_rht_params = { .nelem_hint = 3, /* start small */ .automatic_shrinking = true, .head_offset = offsetof(struct sta_info, hash_node), .key_offset = offsetof(struct sta_info, addr), .key_len = ETH_ALEN, .max_size = CONFIG_MAC80211_STA_HASH_MAX_SIZE, }; static const struct rhashtable_params link_sta_rht_params = { .nelem_hint = 3, /* start small */ .automatic_shrinking = true, .head_offset = offsetof(struct link_sta_info, link_hash_node), .key_offset = offsetof(struct link_sta_info, addr), .key_len = ETH_ALEN, .max_size = CONFIG_MAC80211_STA_HASH_MAX_SIZE, }; static int sta_info_hash_del(struct ieee80211_local *local, struct sta_info *sta) { return rhltable_remove(&local->sta_hash, &sta->hash_node, sta_rht_params); } static int link_sta_info_hash_add(struct ieee80211_local *local, struct link_sta_info *link_sta) { lockdep_assert_wiphy(local->hw.wiphy); return rhltable_insert(&local->link_sta_hash, &link_sta->link_hash_node, link_sta_rht_params); } static int link_sta_info_hash_del(struct ieee80211_local *local, struct link_sta_info *link_sta) { lockdep_assert_wiphy(local->hw.wiphy); return rhltable_remove(&local->link_sta_hash, &link_sta->link_hash_node, link_sta_rht_params); } void ieee80211_purge_sta_txqs(struct sta_info *sta) { struct ieee80211_local *local = sta->sdata->local; int i; for (i = 0; i < ARRAY_SIZE(sta->sta.txq); i++) { struct txq_info *txqi; if (!sta->sta.txq[i]) continue; txqi = to_txq_info(sta->sta.txq[i]); ieee80211_txq_purge(local, txqi); } } static void __cleanup_single_sta(struct sta_info *sta) { int ac, i; struct tid_ampdu_tx *tid_tx; struct ieee80211_sub_if_data *sdata = sta->sdata; struct ieee80211_local *local = sdata->local; struct ps_data *ps; if (test_sta_flag(sta, WLAN_STA_PS_STA) || test_sta_flag(sta, WLAN_STA_PS_DRIVER) || test_sta_flag(sta, WLAN_STA_PS_DELIVER)) { if (sta->sdata->vif.type == NL80211_IFTYPE_AP || sta->sdata->vif.type == NL80211_IFTYPE_AP_VLAN) ps = &sdata->bss->ps; else if (ieee80211_vif_is_mesh(&sdata->vif)) ps = &sdata->u.mesh.ps; else return; clear_sta_flag(sta, WLAN_STA_PS_STA); clear_sta_flag(sta, WLAN_STA_PS_DRIVER); clear_sta_flag(sta, WLAN_STA_PS_DELIVER); atomic_dec(&ps->num_sta_ps); } ieee80211_purge_sta_txqs(sta); for (ac = 0; ac < IEEE80211_NUM_ACS; ac++) { local->total_ps_buffered -= skb_queue_len(&sta->ps_tx_buf[ac]); ieee80211_purge_tx_queue(&local->hw, &sta->ps_tx_buf[ac]); ieee80211_purge_tx_queue(&local->hw, &sta->tx_filtered[ac]); } if (ieee80211_vif_is_mesh(&sdata->vif)) mesh_sta_cleanup(sta); cancel_work_sync(&sta->drv_deliver_wk); /* * Destroy aggregation state here.

Until the handshake * is complete, the control device will fail all write(2)s. * * The handshake is simple. First, the client reads until EOF. Each line * of output is a supported protocol tag. All protocol tags are a single * character followed by a two hex digit version number. Currently the * only things supported is T01, for "Text-base version 0x01". Next, the * client writes the version they would like to use, including the newline. * Thus, the protocol tag is 'T01\n'. If the version tag written is * unknown, -EINVAL is returned. Once the negotiation is complete, the * client can start sending messages. * * The T01 protocol has three messages. First is the "SETN" message. * It has the following syntax: * * SETN<space><8-char-hex-nodenum><newline> * * This is 14 characters. * * The "SETN" message must be the first message following the protocol. * It tells ocfs2_control the local node number. * * Next comes the "SETV" message. It has the following syntax: * * SETV<space><2-char-hex-major><space><2-char-hex-minor><newline> * * This is 11 characters. * * The "SETV" message sets the filesystem locking protocol version as * negotiated by the client. The client negotiates based on the maximum * version advertised in /sys/fs/ocfs2/max_locking_protocol.

The proportions are measured with * exponentially decaying history to give smooth transitions. A formula * expressing proportion of event of type 'j' is: * * p_{j} = (\Sum_{i>=0} x_{i,j}/2^{i+1})/(\Sum_{i>=0} x_i/2^{i+1}) * * Where x_{i,j} is j's number of events in i-th last time period and x_i is * total number of events in i-th last time period. * * Note that p_{j}'s are normalised, i.e. * * \Sum_{j} p_{j} = 1, * * This formula can be straightforwardly computed by maintaining denominator * (let's call it 'd') and for each event type its numerator (let's call it * 'n_j'). When an event of type 'j' happens, we simply need to do: * n_j++; d++; * * When a new period is declared, we could do: * d /= 2 * for each j * n_j /= 2 * * To avoid iteration over all event types, we instead shift numerator of event * j lazily when someone asks for a proportion of event j or when event j * occurs.
