* 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.

| | | | | | | | | | | | The patch fixes the misuse of microsecond with millisecond in the polling mechanism of the iwlwifi driver. The impact of this problem is the unacceptable latency for the whole system (especially during bringing down the wlan interface).

* iwlwifi: keep 3945 and 4965 headers separateChristoph Hellwig2008-01-281-431/+0
| | | | | | | | | | | | | The iwl3945 and iwl4965 devices share some common structure, but with a lot of difference split all over. Currently the two drivers share a lot of headers and use ugly preprocessor magic to manage the difference. This patch keeps two entirely separate copies of the headers to get rid of these hacks an ease future development.
