Some products (So) may have two different types of products with different mac-type that are otherwise equivalent, and have the same PNVM data, so the PNVM file will contain two (or perhaps later more) HW-type TLVs. Accept the file and use the data section that contains any matching entry.

2021-06-22iwlwifi: mvm: honour firmware SMPS requestsJohannes Berg1-0/+26
The firmware can now request SMPS (due to thermal conditions), add some code to honour such requests and bubble them up through the stack, subject to our other SMPS constraints, e.g. from Bluetooth. Then, if the firmware requests SMPS, then we know that it supports a small extension to the PHY configuration API where a chain mask of 0 means "use 1 but pick which one yourself", so in this case we use that extension. During firmware restart, we stay in the previous state, and the FW will send us a notification at startup (only) if the temperature is below the lower or above the high threshold, to sync the state.

2021-04-14iwlwifi: mvm: Add support for 6GHz passive scanIlan Peer2-0/+11
When doing scan while 6GHz channels are not enabled, the 6GHz band is not scanned. Thus, if there are no APs on the 2GHz and 5GHz bands (that will allow discovery of geographic location etc. that would allow enabling the 6GHz channels) but there are non collocated APs on 6GHz PSC channels these would never be discovered. To overcome this, FW added support for performing passive UHB scan in case no APs were discovered during scan on the 2GHz and 5GHz channels. Add support for enabling such scan when the following conditions are met: - 6GHz channels are supported but not enabled by regulatory. - Station interface is not associated or less than a defined time interval passed from the last resume or HW reset flows. - At least 4 channels are included in the scan request - The scan request includes the widlcard SSID. - At least 50 minutes passed from the last 6GHz passive scan.

2021-02-12iwlwifi: remove incorrect comment in pnvmLuca Coelho1-5/+0
We use this driver as a backport that also runs on older kernels (as part of the backports project). So we use some checks to backport or prevent code from compiling in incompatible kernel version. When I took one of the PNVM patches from the backport, I accidentally left the comment that a certain part of the code doesn't work in older kernels. This obviously should never be valid for the mainline. Remove this comment.

2021-02-11iwlwifi: pnvm: increment the pointer before checking the TLVLuca Coelho1-3/+3
If the SKU_ID doesn't match, we don't increment the pointer and keep checking the same TLV over and over again. We need to increment the pointer in all situtations, namely if the TLV is not a SKU_ID, if the SKU_ID matched or if the SKU_ID didn't match. So we can increment the pointer already before checking for these conditions to solve the problem.

2021-02-11iwlwifi: pnvm: set the PNVM again if it was already loadedLuca Coelho1-1/+6
When the interface goes up, we have already loaded the PNVM during init, so we don't load it anymore. But we still need to set the PNVM values in the context so that the FW can load it again. Call set_pnvm when the PNVM is already loaded and change the trans_pcie implementation to accept a second call to set_pnvm when we have already allocated and, in this case, only set the values without allocating again.

2021-02-11iwlwifi: mvm: Check ret code for iwl_mvm_load_nvm_to_nicAbhishek Naik1-1/+2
Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load NVM to nic func fails and NVM is not loaded to fw properly, then fw may behave badly and lead to some strange issue. This commit will analyze return value and if load NVM to nic has failed, then the error code is sent to the previous func, which will trigger WRT log collection. iwl_fw_dbg_error_collect() func collects dump only if tri type is FW_DBG_TRIGGER_ALIVE_TIMEOUT. But when Load NVM to nic function fails trig_type is FW_DBG_TRIGGER_DRIVER. This commit also has code changes to collect dump when trig_type is FW_DBG_TRIGGER_DRIVER.

2021-02-11iwlwifi: mvm: add RFI-M supportGregory Greenman3-0/+71
RF Interference Mitigation is a new feature targeted to handle the problem of interference between DDR memory and WiFi. The role of the driver is to configure FW with the table holding a mapping between problematic channels/bands and the corresponding frequencies. This patch adds RFI infrastructure and adds two debugfs hooks: - send RFI configuration command (currently with a default table) which will reset feature in the FW - read the table, used by the FW (which can be a subset of the table that driver sent).

iwl_acpi_get_wifi_pkg() may return a valid pointer (meaning success), while `tbl_rev` is invalid (equel to 1). In this case, we will treat that as an error. Subsequent "users" of this "error code" may either check for nonzero (good; pointers are never zero) or negative (bad; pointers may be "positive") fix that by splitting the if statement. First check if IS_ERR(wifi_pkg) and then if tbl_rev != 0.
