Typically, such an event will be propagated to NFC Core from MSGRXWQ context. + +Error management +---------------- + +Errors that occur synchronously with the execution of an NFC Core request are +simply returned as the execution result of the request. These are easy. + +Errors that occur asynchronously (e.g. in a background protocol handling thread) +must be reported such that upper layers don't stay ignorant that something +went wrong below and know that expected events will probably never happen. +Handling of these errors is done as follows: + +- driver (pn544) fails to deliver an incoming frame: it stores the error such +that any subsequent call to the driver will result in this error. Then it calls +the standard nfc_shdlc_recv_frame() with a NULL argument to report the problem +above. shdlc stores a EREMOTEIO sticky status, which will trigger SMW to +report above in turn. + +- SMW is basically a background thread to handle incoming and outgoing shdlc +frames. This thread will also check the shdlc sticky status and report to HCI +when it discovers it is not able to run anymore because of an unrecoverable +error that happened within shdlc or below. If the problem occurs during shdlc +connection, the error is reported through the connect completion. + +- HCI: if an internal HCI error happens (frame is lost), or HCI is reported an +error from a lower layer, HCI will either complete the currently executing +command with that error, or notify NFC Core directly if no command is executing. + +- NFC Core: when NFC Core is notified of an error from below and polling is +active, it will send a tag discovered event with an empty tag list to the user +space to let it know that the poll operation will never be able to detect a tag. +If polling is not active and the error was sticky, lower levels will return it +at next invocation. diff --git a/MAINTAINERS b/MAINTAINERS index ce7398e..b4321fb 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -3661,14 +3661,6 @@ T: git git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi.git S: Supported F: drivers/net/wireless/iwlwifi/ -INTEL WIRELESS MULTICOMM 3200 WIFI (iwmc3200wifi) -M: Samuel Ortiz <samuel.ortiz@intel.com> -M: Intel Linux Wireless <ilw@linux.intel.com> -L: linux-wireless@vger.kernel.org -S: Supported -W: http://wireless.kernel.org/en/users/Drivers/iwmc3200wifi -F: drivers/net/wireless/iwmc3200wifi/ - INTEL MANAGEMENT ENGINE (mei) M: Tomas Winkler <tomas.winkler@intel.com> L: linux-kernel@vger.kernel.org diff --git a/drivers/bcma/bcma_private.h b/drivers/bcma/bcma_private.h index b81755b..f6589eb 100644 --- a/drivers/bcma/bcma_private.h +++ b/drivers/bcma/bcma_private.h @@ -10,6 +10,15 @@ #define BCMA_CORE_SIZE 0x1000 +#define bcma_err(bus, fmt, ...) \ + pr_err("bus%d: " fmt, (bus)->num, ##__VA_ARGS__) +#define bcma_warn(bus, fmt, ...) \ + pr_warn("bus%d: " fmt, (bus)->num, ##__VA_ARGS__) +#define bcma_info(bus, fmt, ...) \ + pr_info("bus%d: " fmt, (bus)->num, ##__VA_ARGS__) +#define bcma_debug(bus, fmt, ...) \ + pr_debug("bus%d: " fmt, (bus)->num, ##__VA_ARGS__) + struct bcma_bus; /* main.c */ diff --git a/drivers/bcma/core.c b/drivers/bcma/core.c index bc6e892..63c8b47 100644 --- a/drivers/bcma/core.c +++ b/drivers/bcma/core.c @@ -75,7 +75,7 @@ void bcma_core_set_clockmode(struct bcma_device *core, udelay(10); } if (i) - pr_err("HT force timeout\n"); + bcma_err(core->bus, "HT force timeout\n"); break; case BCMA_CLKMODE_DYNAMIC: bcma_set32(core, BCMA_CLKCTLST, ~BCMA_CLKCTLST_FORCEHT); @@ -102,9 +102,9 @@ void bcma_core_pll_ctl(struct bcma_device *core, u32 req, u32 status, bool on) udelay(10); } if (i) - pr_err("PLL enable timeout\n"); + bcma_err(core->bus, "PLL enable timeout\n"); } else { - pr_warn("Disabling PLL not supported yet!\n"); + bcma_warn(core->bus, "Disabling PLL not supported yet!\n"); } } EXPORT_SYMBOL_GPL(bcma_core_pll_ctl); @@ -120,8 +120,8 @@ u32 bcma_core_dma_translation(struct bcma_device *core) else return BCMA_DMA_TRANSLATION_DMA32_CMT; default: - pr_err("DMA translation unknown for host %d\n", - core->bus->hosttype); + bcma_err(core->bus, "DMA translation unknown for host %d\n", + core->bus->hosttype); } return BCMA_DMA_TRANSLATION_NONE; } diff --git a/drivers/bcma/driver_chipcommon.c b/drivers/bcma/driver_chipcommon.c index e9f1b3f..a4c3ebc 100644 --- a/drivers/bcma/driver_chipcommon.c +++ b/drivers/bcma/driver_chipcommon.c @@ -44,7 +44,7 @@ void bcma_core_chipcommon_init(struct bcma_drv_cc *cc) if (cc->capabilities & BCMA_CC_CAP_PMU) bcma_pmu_init(cc); if (cc->capabilities & BCMA_CC_CAP_PCTL) - pr_err("Power control not implemented!\n"); + bcma_err(cc->core->bus, "Power control not implemented!\n"); if (cc->core->id.rev >= 16) { if (cc->core->bus->sprom.leddc_on_time && @@ -137,8 +137,7 @@ void bcma_chipco_serial_init(struct bcma_drv_cc *cc) | BCMA_CC_CORECTL_UARTCLKEN); } } else { - pr_err("serial not supported on this device ccrev: 0x%x\n", - ccrev); + bcma_err(cc->core->bus, "serial not supported on this device ccrev: 0x%x\n", ccrev); return; } diff --git a/drivers/bcma/driver_chipcommon_pmu.c b/drivers/bcma/driver_chipcommon_pmu.c index 61ce405..4432617 100644 --- a/drivers/bcma/driver_chipcommon_pmu.c +++ b/drivers/bcma/driver_chipcommon_pmu.c @@ -3,7 +3,8 @@ * ChipCommon Power Management Unit driver * * Copyright 2009, Michael Buesch <m@bues.ch> - * Copyright 2007, Broadcom Corporation + * Copyright 2007, 2011, Broadcom Corporation + * Copyright 2011, 2012, Hauke Mehrtens <hauke@hauke-m.de> * * Licensed under the GNU/GPL.

The former is used to send - * UMAC commands (see UMAC_CMD_OPCODE_* from umac.h) - * while the latter is used for sending commands to the - * LMAC. If you look at LMAC commands you'll se that they - * are actually regular iwlwifi target commands encapsulated - * into a special UMAC command called UMAC passthrough. - * This is due to the fact the host talks exclusively - * to the UMAC and so there needs to be a special UMAC - * command for talking to the LMAC. - * This is how a wifi command is laid out: - * ------------------------ - * | iwm_udma_out_wifi_hdr | - * ------------------------ - * | SW meta_data (32 bits) | - * ------------------------ - * | iwm_dev_cmd_hdr | - * ------------------------ - * | payload | - * | .... | - * - * - non-wifi, or general commands: - * Those commands are handled by the device's bootrom, - * and are typically sent when the UMAC and the LMAC - * are not yet available. - * * This is how a non-wifi command is laid out: - * --------------------------- - * | iwm_udma_out_nonwifi_hdr | - * --------------------------- - * | payload | - * | .... | - - * - * All the commands start with a UDMA header, which is - * basically a 32 bits field. The 4 LSB there define - * an opcode that allows the target to differentiate - * between wifi (opcode is 0xf) and non-wifi commands - * (opcode is [0..0xe]). - * - * When a command (wifi or non-wifi) is supposed to receive - * an answer, we queue the command buffer. When we do receive - * a command response from the UMAC, we go through the list - * of pending command, and pass both the command and the answer - * to the rx handler. Each command is sent with a unique - * sequence id, and the answer is sent with the same one. This - * is how we're supposed to match an answer with its command. - * See rx.c:iwm_rx_handle_[non]wifi() and iwm_get_pending_[non]wifi() - * for the implementation details. - */ -#include <linux/kernel.h> -#include <linux/netdevice.h> -#include <linux/slab.h> - -#include "iwm.h" -#include "bus.h" -#include "hal.h" -#include "umac.h" -#include "debug.h" -#include "trace.h" - -static int iwm_nonwifi_cmd_init(struct iwm_priv *iwm, - struct iwm_nonwifi_cmd *cmd, - struct iwm_udma_nonwifi_cmd *udma_cmd) -{ - INIT_LIST_HEAD(&cmd->pending);
