2015-01-22iwlwifi: mvm: fix rx chains configuration in phy ctxt cmdLiad Kaufman1-1/+1
In the PHY_CTXT command sent to the FW the TX chains were indeed configured by the values of both FW TLVs and of NVM, but the RX chains were left out and configured only by FW TLV. This causes problems in 4165 HW, where there are 1x1 antennas, and the wrong configuration denies the driver from connecting to the AP.

Our legal structure changed at some point (see wikipedia), but we forgot to immediately switch over to the new copyright notice.

2014-07-07iwlwifi: mvm: disallow new TDLS stations when appropriateArik Nemtsov1-0/+26
HW/FW constraints dictate that TDLS should only be used when a single phy ctx is active. We also support at most 4 TDLS peers. We don't support TDLS on a P2P vif. Unify and move a phy-ctx counting implementation from the power-mgmt code in order to simplify implementation.

2014-05-19iwlwifi: mvm: don't allow diversity if BT Coex / TT forbid itEmmanuel Grumbach1-2/+1
We should not allow diversity when BT Coex needs the second antenna. Thermal Throttling can also request to stop using the second antenna. Honour those requests.

In some situations (see comment) it makes sense to enable both chains (if available) to get better throughput by having chain diversity available. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

CMD_SYNC is really 0 which is confusing: if (cmd.flags & CMD_SYNC) is always false. Fix this by simply removing its definition. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>

2013-05-29iwlwifi: mvm: implement D3 testingJohannes Berg1-1/+2
For testing the D3 (WoWLAN) firmware, it is useful to be able to run the firmware with instrumentation while the host isn't sleeping and can poke at the firmware debug logging etc. Implement this by a debugfs file. When the file is opened the D3 firmware is loaded and all regular commands are blocked. While the file is being read, poll the firmware's PME status flag and report EOF once it changes to non-zero. When it is closed, do (most of) the resume processing. This lets a user just "cat" the file. Pressing Ctrl-C to kill the cat process will resume the firwmare as though the platform resumed for non-wireless reason and when the firmware wants to wake up reading from the file automatically completes. Unlike in real suspend, only disable interrupts and don't reset the TX/RX hardware while in the test mode. This is a workaround for some interrupt problems that happen only when the PCIe link isn't fully reset (presumably by changing the PCI config space registers which the core PCI code does.) Note that while regular operations are blocked from sending commands to the firmware, they could still be made and cause strange mac80211 issues. Therefore, while using this testing feature you need to be careful to not try to disconnect, roam or similar, and will see warnings for such attempts. Als note that this requires an upcoming firmware change to tell the driver the location of the PME status flag in SRAM. D3 test will fail if the firmware doesn't report the pointer.

2013-05-13iwlwifi: mvm: Change PHY context handlingIlan Peer1-32/+0
1. All the phy contexts are added immediately after the firmware is loaded and up. 2. Whenever a PHY context needs to be used, its reference counter is incremented and the PHY context is being configured to the appropriate configuration. 3. When a PHY context is no longer needed, its reference count is decremented. 4. PHY contexts are never removed.

2013-05-13iwlwifi: mvm: Loosen the channel context/phy context couplingIlan Peer1-39/+34
In current implementation, the phy context is tightly coupled with the channel context. This complicates the possibility of using the same phy context for both netdev interfaces and the P2P Device interface. To loosen this coupling: 1. Manage all the phy contexts in the mvm op mode, and only save the phy context id in the chanctx memory. 2. Reference count the phy contexts and free them only when they are not longer used (both by mac80211 and P2P Device).
