It is possible that the BSS context is not active (for example
when the current mode is set to GO), or that the vif->type is
different than station. In such a case we cannot
call mac80211 to report the average rssi for the interface
(the function assumes that the vif is valid and that the type
is station).

This causes a race condition in mac80211. To fix this, delay the ROC notification to mac80211 until the device reported the Tx status for all frames in the aux queue.

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.

* [PATCH 25/29] iwlwifi: refactor EEPROM reading/parsing 2012-06-06 13:21 [PATCH 01/29] iwlwifi: Check BSS ctx active before call mac80211 Johannes Berg ` (22 preceding siblings ...) 2012-06-06 13:22 ` [PATCH 24/29] iwlwifi: configure the SKU in the HW Johannes Berg @ 2012-06-06 13:22 ` Johannes Berg 2012-06-06 13:22 ` [PATCH 26/29] iwlwifi: fix typo 'IWL_WATCHHDOG_DISABLED' Johannes Berg ` (4 subsequent siblings) 28 siblings, 0 replies; 32+ messages in thread From: Johannes Berg @ 2012-06-06 13:22 UTC (permalink / raw) To: linux-wireless; +Cc: Johannes Berg From: Johannes Berg <johannes.berg@intel.com> 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.
