* iwlagn: all function iwl-io.c receive iwl_busEmmanuel Grumbach2011-08-291-32/+29Star
| | | | | | | | Which means that iwl-io.c doesn't need to include iwl-dev.h any more. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* iwlagn: simplify the bus architectureEmmanuel Grumbach2011-07-211-3/+4
| | | | | | | | | | | | | | | | | | | Call iwl_probe with a ready iwl_bus struct. This means that the bus layer assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to iwl_probe. The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.

* iwlagn: move PCI related operations from probe and remove to PCI layerEmmanuel Grumbach2011-06-181-3/+3
| | | | | | | | | | | Since we have now a PCI layer, all the init and deinit code that is PCI related should move to there. Also move the IO functions: read8/read32/write32. They need hw_base which is killed from priv. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
* iwlagn: introduce silent grabbing of NIC accessJohannes Berg2011-04-301-0/+1
| | | | | | | | | | | | | | | There are a few cases like the WoWLAN support I'm writing that require attempting to access the NIC when it is known that it might not be accessible, e.g. after the system woke up and the platform might have reset the device. To avoid messages in this case, introduce the new function iwl_grab_nic_access_silent(), it will only return an error status.

* iwlagn: simplify error table readingJohannes Berg2011-04-221-0/+10
| | | | | | | | | | | | | | The current code to read the error table header just hardcodes all the offsets, which is a bit hard to understand. We can read in the entire header (as much as we need) into a structure, and then take the data from there, which makes it easier to understand. To read a bigger blob we also don't need to grab NIC access for each word read, making the code more efficient.

* iwlagn: move IO functions out of lineJohannes Berg2011-04-071-468/+21Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This generates a massive reduction in module size: with debug: text data bss dec hex filename 670300 13136 420 683856 a6f50 iwlagn.ko (before) 388347 13136 408 401891 621e3 iwlagn.ko (after) without debug: text data bss dec hex filename 528575 13072 420 542067 84573 iwlagn.ko (before) 294192 13072 408 307672 4b1d8 iwlagn.ko (after) This also removes all the IO debug functionality since it can easily be replaced by tracing, and makes the code unnecessarily complex. I haven't done any CPU utilisation measurements, but given that the hotpaths don't use much IO it is not likely to have a negative impact; in fact, the size reduction will reduce cache pressure which possibly improves performance. Finally, an unused function or two were removed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: John W.

* | iwlwifi: don't include iwl-dev.h from iwl-devtrace.hTejun Heo2010-03-301-0/+1
|/ | | | | | | | | | | | | | | iwl-devtrace.h is used to declare and define trace points and including iwl-dev.h from the file, which in turn includes other generic headers, can lead to problems like generating duplicate copies of generic trace points depending on the order of includes. Don't include iwl-dev.h from iwl-devtrace.h but include it from its users - iwl-io.h and iwl-devtrace.c.

* iwlwifi: device tracingJohannes Berg2009-10-071-2/+14
| | | | | | | | | | | | | | | | In order to have an easier way to debug issues, create trace events (using the ftrace framework) that will allow us to follow exactly what the driver is doing with the device. The text format isn't all that useful, but the binary format can also be obtained easily via debugfs and then analysed on the fly or offline with debugging tools.

* iwlcore: register locksMohamed Abbas2009-05-221-94/+159
| | | | | | | | | | | | | | | Add new lock to be used when accessing some registers. Also move the register lock and iwl_grab_nic_access inside the function for register access. This will prevent from forgetting to hold locks and nic access in the right way and make code easier to maintain. We over use the priv->lock spin lock and I guess we need to add new one for Tx queue after that we might need to change most of these lock to BH and just keep priv->lock as irq type.

* iwl3945: fix deep sleep when removing the driver.Abbas, Mohamed2009-01-291-1/+1
| | | | | | | | | | | | | | | | | | | | | A warning message "MAC is in deep sleep" sometimes happen when user removes the driver. This warning is related to card not being ready. In __iwl3945_down function some of the going down steps are in wrong order, to fix this this patch do the following: 1- make sure we are calling iwl3945_apm_reset and iwl3945_apm_stop in the right order. 2- make sure we set CSR_GP_CNTRL_REG_FLAG_INIT_DONE in apm_reset before poll on CSR_GP_CNTRL_REG_FLAG_MAC_CLOCK_READY. 3- set correct polling counter.
