2012-06-13iwlwifi: don't modify the timer if we don't TxEmmanuel Grumbach1-1/+2
In fragmentation we don't update the write pointer of the HW immediately. So we shouldn't modify the timer in that case. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-06-13iwlwifi: print even more info when a queue is stuckEmmanuel Grumbach1-4/+22
Since the queue gets stuck from time to time, we are trying to get as much information as we can when this occurs. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-06-13iwlwifi: remove lock around txq_enableEmmanuel Grumbach3-26/+5
This locking isn't needed. The only locking we need is when we access prph registers but there is already a separate lock for that. Since we haven't returned from the mac80211's IEEE80211_AMPDU_TX_OPERATIONAL ampdu_action, we cannot receive any Tx frame for that sta / tid while enabling the queue.

2012-06-13iwlwifi: don't configure a txq that is being disabledEmmanuel Grumbach2-47/+31
This is not needed, we just need to tell the SCD not to use that queue. We will reconfigure that queue when we will use it again. Clean up a bit the code on the way. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Print some more info from the SCD's SRAM and dump the TRB from the FH. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-06-13Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller2-2/+27
Conflicts: MAINTAINERS drivers/net/wireless/iwlwifi/pcie/trans.c The iwlwifi conflict was resolved by keeping the code added in 'net' that turns off the buggy chip feature. The MAINTAINERS conflict was merely overlapping changes, one change updated all the wireless web site URLs and the other changed some GIT trees to be Johannes's instead of John's.

2012-06-06iwlwifi: fix typo 'IWL_WATCHHDOG_DISABLED'Paul Bolle2-2/+2
Commit 7c5ba4a830cbb730770129b0004e2a06e47dbac5 ("iwlwifi: move queue watchdog into transport") introduced the named constant 'IWL_WATCHHDOG_DISABLED'. Rename it to 'IWL_WATCHDOG_DISABLED'.

2012-06-06iwlwifi: refactor EEPROM reading/parsingJohannes Berg4-0/+65
The EEPROM reading/parsing code is all mixed in the driver today, and the EEPROM is parsed only when we access data from it. This is problematic because the NVM needs to be parsed and that is independent of reading it. Also, the NVM format for new devices will be different and probably require a new parser. Therefore refactor the reading and parsing and create two independent components. Reading the EEPROM requires direct hardware accesses and therefore access to the transport, but parsing is independent and can be done on an NVM blob.

2012-06-06iwlwifi: allocate Tx cmd pool per deviceEmmanuel Grumbach1-0/+19
Different transports will have different needs: New tranports need headroom for their own use before the Tx cmd. So allocate the Tx cmd pool in the transport and give it a unique name based on dev_name.

2012-06-06iwlwifi: s/txq_setup/txq_enableEmmanuel Grumbach3-39/+40
We need to be able to enable / disable Tx queues in HW dynamically. So this function is no longer related to AGG only. It can do the job for any queue, even AC ones. Change the name to better reflect its role. Also use the new function to configure the AC / CMD queues in tx_start.

2012-06-06iwlwifi: first config the SCD queues, then activate themEmmanuel Grumbach1-18/+18

2012-06-06iwlwifi: SCD_INT_MSK is obsolete - don't update itEmmanuel Grumbach2-7/+0
The scheduler can issue an interrupt when moving the read pointer. To get this interrupt, the driver needs to configure what queue can issue an interrupt when its read pointer moves in the scheduler: this is the SCD_INT_MSK. The driver also needs to enable the interrupt in CSR_INT_MASK (bit CSR_INT_BIT_SCD). Since we don't enable the scheduler interrupt in CSR_INT_MASK, there is no point in requesting an interrupt from the scheduler: it will be masked anyway. So don't configure the scheduler to issue interrupts at all. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
