iwlwifi: mvm: Handle power management constraints for additional use-cases Today, the driver logic looks for the conditions to disable power management albeit power management should be enabled in a very few distinct cases. This patch changes the driver logic to enable power management once the required conditions met. While at it, make some housekeeping and support a few additional use cases: a) Add support for a standalone p2p client: Power management should be enabled for a P2P client MAC only if the firmware supports it (TLV flag is set). Instead we used the DCM flag, therefore we didn't cover use cases that did not include the DCM flag. b) Add support to Same-Channel-Mode (SCM): If both clients share the same channel (SCM), and there are no other active vifs in the system, power management should be enabled only if the firmware supports this (TLV flag is set). c) Fix power management logic for GO/AP: Today, when we detect an active GO / AP MAC - we disable power management for all the vifs altogether. Actually, the correct behavior is to enable power management on a client if on a different channel (based on the firmware capabilities). d) Housekeeping - Along with that, this patch includes some code-reorganizing: Today the logic of disabling power is scattered across several functions, specifically in the iterator. For the sake of both readability and scalability, we moved this logic to its applicable function, leaving the iterator gather information only. Furthermore, as power management is a MAC-related attribute, we moved the power management member to the iwl_mvm_vif structure.

iwlwifi: mvm: implement D3 testing 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.

iwlwifi: mvm: add a loose synchronization of the NSSN across Rx queues In order to support MSI-X efficiently, we want to avoid communication across Rx queues. Each Rx queue should have all the data it needs to process a packet. The reordering buffer is a challenge in the MSI-X world since we can have a single BA session whose packets are directed to different queues. This is why each queue has its own reordering buffer. The hardware is able to hint the driver whether we have a hole or not, which allows the driver to know whether it can release a packet or not. This indication is called NSSN. Roughly, if the packet's SN is lower than the NSSN, we can release the packet to the stack. The NSSN is the SN of the newest packet received without any holes + 1. This is working as long as we don't have packets that we release because of a timeout. When that happens, we could have taken the decision to release a packet after we have been waiting for its predecessor for too long. If this predecessor comes later, we have to drop it because we can't release packets out of order. In that case, the hardware will give us an indication that we can we release the packet (SN < NSSN), but the packet still needs to be dropped. This is why we sometimes need to ignore the NSSN and we track the head_sn in software. Here is a specific example of this: 1) Rx queue 1 got packets: 480, 482, 483 2) We release 480 to to the stack and wait for 481 3) NSSN is now 481 4) The timeout expires 5) We release 482 and 483, NSSN is still 480 6) 481 arrives its NSSN is 484. We need to drop 481 even if 481 < 484. This is why we'll update the head_sn to 484 at step 2. The flow now is: 1) Rx queue 1 got packets: 480, 482, 483 2) We release 480 to to the stack and wait for 481 3) NSSN is now 481 / head_sn is 481 4) The timeout expires 5) We release 482 and 483, NSSN is still 480 but head_sn is 484. 6) 481 arrives its NSSN is 484, but head_sn is 484 and we drop it. This code introduces another problem in case all the traffic goes well (no hole, no timeout): Rx queue 1: 0 -> 483 (head_sn = 484) Rx queue 2: 501 -> 4095 (head_sn = 0) Rx queue 2: 0 -> 480 (head_sn = 481) Rx queue 1: 481 but head_sn = 484 and we drop it. At this point, the SN of queue 1 is far behind: more than 4040 packets behind. Queue 1 will consider 481 "old" because 481 is in [501-64:501] whereas it is a very new packet. In order to fix that, send an Rx notification from time to time (twice across the full set of 4096 packets) to make sure no Rx queue is lagging too far behind. What will happen then is: Rx queue 1: 0 -> 483 (head_sn = 484) Rx queue 2: 501 -> 2047 (head_sn = 2048) Rx queue 1: Sync nofication (head_sn = 2048) Rx queue 2: 2048 -> 4095 (head_sn = 0) Rx queue 1: Sync notification (head_sn = 0) Rx queue 2: 1 -> 481 (head_sn = 482) Rx queue 1: 481 and head_sn = 0. In queue 1's data, head_sn is now 0, the packet coming in is 481, it'll understand that the new packet is new and it won't be dropped.

iwlwifi: mvm: implement D3 testing 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.
