In order to avoid NIC destruction due to high temperature, CT kill will power down the NIC. To avoid this, thermal throttling will decrease throughput to prevent the NIC from reaching the temperature at which CT kill is performed. Signed-off-by:

The MVM firmware doesn't communicate this way, it instead assumes D3 configuration is complete after a specific host command (which must be last) has been sent. Handling this bit thus belongs into the firmware API code, i.e. DVM. Signed-off-by:

In 63b77bf4 iwlwifi: dvm: don't send zeroed LQ cmd I tried to avoid to send zeroed LQ cmd, but I made a (very) stupid mistake in the memcmp. Since this patch has been ported to stable, the fix should go to stable too. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58341 Cc: stable@vger.kernel.org Reported-by:

When different images can (soon) be accessed through this file, storing the section offset/length on first access to the file breaks (or needs manual reset). Avoid this by not storing the offset/length values but using them locally in the function only. That way, the correct values are always used. While at it, correct the check that firmware is loaded.

If RF-kill is asserted while a device is initialized, the firmware INIT image can now be run to retrieve the NVM data and register to mac80211 properly. Previously, the initialisation would fail in this scenario and the driver wouldn't register with mac80211 at all, making the device unusable. Signed-off-by:

Some newer devices will be integrated into the platform more deeply and will not have embedded NVM (EEPROM/OTP). To support such devices the NVM data must be provided by the platform, allow loading the data via request_firmware() and then send it to the device as needed. Signed-off-by:

As the new MVM firmware files package the DATA section first, and debugfs files want to access the DATA and not INST section, reverse the order here. This is only relevant for debugfs code that accesses the SRAM DATA section and uses this constant to access the section. Reviewed-by:

Move the counter for non-AMPDU frames to mvm. It is needed for the drain flow which happens once the ieee80211_sta has been freed, so keeping it in iwl_mvm_sta which is embed into ieee80211_sta is not a good idea. Also, since its purpose it to remove the STA in the fw only after all the frames for this station have exited the shared Tx queues, we need to decrement it in the reclaim flow. This flow can happen after ieee80211_sta has been removed, which means that we have no iwl_mvm_sta there. So we can't know what is the vif type. Hence, we know audit these frames for all the vif types. In order to avoid spawning sta_drained_wk all the time, we now check that we are in a flow in which draining might happen - only when mvmsta is NULL. This is better than previous code that would spawn sta_drained_wk all the time in AP mode. Cc: stable@vger.kernel.org [3.9] Signed-off-by:

In the normal flow first MAC_CONTEXT_CMD for particular interface is never sent while associated. The exception is fw restart flow when resuming from suspend when WoWLAN is enabled. In this case successive "add" and "modify" MAC_CONTEXT_CMD commands may be sent with assoc flag set what cause FW mal functioning. To prevent this never set assoc flag in MAC_CONTEXT_CMD with action "add". Cc: stable@vger.kernel.org Signed-off-by:

The patch is an optimization, that eliminates unnecessary binding context switching and allows the P2P Device MAC to use the same channel as an existing netdev interface. For each ROC call, check if there is already a channel/phy context that can be used for the P2P Device. If such channel is found, unbind the P2P Device from its current phy context, and bind it to the already used channel/phy context. In case that the phy context is shared, and there is a need to change it, create a new phy context, unbind and create a new binding. Signed-off-by:

Many times, a NIC error is the result of a bad command sent to the device. If the command was sent synchronously, then we'll currently print a message when the command is aborted containing the command. It can be very useful to also see the stack dump though, so also print that. Reviewed-by:

In theory, the firmware format allows changing the data section offset. This may not be used today, but there's no reason for the driver to assume the data section is always at 0x800000 as it can know better. Reviewed-by:

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. Signed-off-by:

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). Signed-off-by:

Users complained about allocation failures, so we loaded the firmware in small chunks (PAGE_SIZE). This makes the firmware restart considerably slower. So, always prefer to load it in one shot allocating a big chunk of coherent, and use smaller chunks as a fallback solution. On my laptop, this reduces the fw loading time from 120ms to 20ms.

He also discovered and fixed some bugs in doing so. When pulling in his patches, I also found a few minor bugs as well and fixed them. This also includes a compile fix for some archs that select the ring buffer but not tracing.
