2015-10-05iwlwifi: dvm: fix D3 firmware PN programmingJohannes Berg1-1/+1
The code to send the RX PN data (for each TID) to the firmware has a devastating bug: it overwrites the data for TID 0 with all the TID data, leaving the remaining TIDs zeroed. This will allow replays to actually be accepted by the firmware, which could allow waking up the system.

2014-12-02iwlwifi: dvm: fix flush support for old firmwareEmmanuel Grumbach1-23/+24
Since the commit below, iwldvm sends the FLUSH command to the firmware. All the devices that use iwldvm have a firmware that expects the _v3 version of this command, besides 5150. 5150's latest available firmware still expects a _v2 version of the FLUSH command. This means that since the commit below, we had a mismatch for this specific device only. This mismatch led to the NMI below: Loaded firmware version: 8.24.2.2 Start IWL Error Log Dump: Status: 0x0000004C, count: 5 0x00000004 | NMI_INTERRUPT_WDG 0x000006F4 | uPc 0x000005BA | branchlink1 0x000006F8 | branchlink2 0x000008C2 | interruptlink1 0x00005B02 | interruptlink2 0x00000002 | data1 0x07030000 | data2 0x00000068 | line 0x3E80510C | beacon time 0x728A0EF4 | tsf low 0x0000002A | tsf hi 0x00000000 | time gp1 0x01BDC977 | time gp2 0x00000000 | time gp3 0x00010818 | uCode version 0x00000000 | hw version 0x00484704 | board version 0x00000002 | hcmd 0x2FF23080 | isr0 0x0103E000 | isr1 0x0000001A | isr2 0x1443FCC3 | isr3 0x11800112 | isr4 0x00000068 | isr_pref 0x000000D4 | wait_event 0x00000000 | l2p_control 0x00000007 | l2p_duration 0x00103040 | l2p_mhvalid 0x00000007 | l2p_addr_match 0x00000000 | lmpm_pmg_sel 0x00000000 | timestamp 0x00000200 | flow_handler This was reported here: https://bugzilla.kernel.org/show_bug.cgi?id=88961 Cc: <stable@vger.kernel.org> Fixes: a0855054e59b ("iwlwifi: dvm: drop non VO frames when flushing") Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-04-08iwlwifi: dvm: handle FLUSH ampdu actions from mac80211Emmanuel Grumbach1-2/+5
Until now we didn't handle properly the FLUSH ampdu action coming from mac80211. This could result in SCD queue leak: mac80211 would STOP_FLUSH an AMPDU Tx session and remove the station. If we had still packets on the ring, we wouldn't deallocate the SCD queue and wait for it to be empty. The indication of the queue being empty comes from the Tx response flow which relies on the tid_data structure. The problem is that this structure has been cleared when the station has been removed. In order to solve this issue, block in the STOP_FLUSH ampdu_action until the SCD queue is flushed, and only then, let mac80211 move forward to remove the station. iwlagn_txfifo_flush had to be enhanced to allow this. The bug fixed here caused the "txq_id mismatch: 12 0" print. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-04-04iwlwifi: sleep for at least 10 secondsJohannes Berg1-1/+8
Many platforms have issues processing a wakeup signal while they're still suspending, and will ignore it. Since our device thinks it woke the platform, and the platform ignored the signal, it will sleep without WoWLAN being enabled as the device disables WoWLAN when having woken the platform. Resolve this by making the device wait for 10 seconds after getting the suspend signal before waking up the platform.

2013-03-20iwlwifi: dvm: don't send HCMD in restart flowEmmanuel Grumbach1-0/+9
There is a race between the restart flow and the workers. The workers are cancelled after the fw is already killed and might send HCMD when there is fw to handle them. Simply check that there is a fw to which the HCMD can be sent before actually sending it.

2012-12-07iwlwifi: Change define and struct names in iwl-eeprom-parse.hEytan Lifshitz1-4/+4
Since we will have several forms of NVM (EEPROM, OTP, etc.) and they will have different layouts, make the parsed data more generic. This allows functional code to be independent of a specific layout. Also change some variables and function names from having "eeprom" to "nvm" in their name.

2012-11-05iwlwifi: fix queue flush confusionJohannes Berg1-15/+14
The flush_control parameter to iwlagn_txfifo_flush is passed as an internal value (context flags) and then sent to the device, that can't be right.

2012-06-06iwlwifi: refactor EEPROM reading/parsingJohannes Berg1-4/+4
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.
