2022-02-18iwlwifi: make iwl_fw_lookup_cmd_ver() take a cmd_idJohannes Berg1-15/+7
Instead of taking the group/command separately, make the function take a combined command ID. In many cases, this allows us to pass an existing command ID (e.g. cmd.id), or introduce a new variable for it, so that we don't use the command ID twice. This way, we can also use LONG_GROUP implicitly, so we don't need to spell that out for many commands. Apart from mvm.h, fw/img.{c,h} changes and some copyright and indentation updates, this was done with spatch: @@ identifier cmd; expression fw, G, C, def; @@ struct iwl_host_cmd cmd = { .id = WIDE_ID(G, C), ... }; ... -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, cmd.id, def) @@ identifier cmd; expression fw, C, def; @@ struct iwl_host_cmd cmd = { .id = C, ... }; ... -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, cmd.id, def) @@ identifier func; expression fw, G, C, mvm, flags, cmd, size, def; type rettype; @@ rettype func(...) { +u32 cmd_id = WIDE_ID(G, C); ... -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, cmd_id, def) ... -iwl_mvm_send_cmd_pdu(mvm, WIDE_ID(G, C), flags, cmd, size) +iwl_mvm_send_cmd_pdu(mvm, cmd_id, flags, cmd, size) ... } @@ identifier func; expression fw, G, C, mvm, flags, cmd, size, def; type rettype; @@ rettype func(...) { +u32 cmd_id = C; ... -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, cmd_id, def) ... -iwl_mvm_send_cmd_pdu(mvm, C, flags, cmd, size) +iwl_mvm_send_cmd_pdu(mvm, cmd_id, flags, cmd, size) ... } @@ expression fw, C, def; @@ -iwl_fw_lookup_cmd_ver(fw, \(IWL_ALWAYS_LONG_GROUP\|LONG_GROUP\), C, def) +iwl_fw_lookup_cmd_ver(fw, C, def) @@ expression fw, C, G, def; @@ -iwl_fw_lookup_cmd_ver(fw, G, C, def) +iwl_fw_lookup_cmd_ver(fw, WIDE_ID(G, C), def) Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]> Link: https://lore.kernel.org/r/iwlwifi.20220128153014.c4ac213cef5c.I6fd9a4fcbcf16ef3a3ae20a2b08ee54ebe06f96f@changeid Signed-off-by: Luca Coelho <[email protected]>
2022-02-18iwlwifi: prefer WIDE_ID() over iwl_cmd_id()Johannes Berg1-5/+4
The order of arguments for iwl_cmd_id() is confusing, and the version is always 0 and thus a useless argument.

2021-12-21iwlwifi: mvm: Increase the scan timeout guard to 30 secondsIlan Peer1-1/+1
With the introduction of 6GHz channels the scan guard timeout should be adjusted to account for the following extreme case: - All 6GHz channels are scanned passively: 58 channels. - The scan is fragmented with the following parameters: 3 fragments, 95 TUs suspend time, 44 TUs maximal out of channel time. The above would result with scan time of more than 24 seconds. Thus, set the timeout to 30 seconds.

2021-04-14iwlwifi: mvm: Add support for 6GHz passive scanIlan Peer1-0/+128
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.

2019-12-30Revert "iwlwifi: mvm: fix scan config command size"Mehmet Akif Tasova1-1/+1
Since v5.4-rc1 was released, iwlwifi started throwing errors when scan commands were sent to the firmware with certain devices (depending on the OTP burned in the device, which contains the list of available channels). For instance: iwlwifi 0000:00:14.3: FW error in SYNC CMD SCAN_CFG_CMD This bug was reported in the ArchLinux bug tracker: https://bugs.archlinux.org/task/64703 And also in a specific case in bugzilla, when the lar_disabled option was set: https://bugzilla.kernel.org/show_bug.cgi?id=205193 Revert the commit that introduced this error, by using the number of channels from the OTP instead of the number of channels that is specified in the FW TLV that tells us how many channels it supports. This reverts commit 06eb547c4ae4382e70d556ba213d13c95ca1801b.

FW scan api ver 11 adds support for some new features, in this version the fw did also some cleanup in the api, which causes the driver not to be able to use the current scan req struct.

2019-10-30iwlwifi: fw api: support new API for scan config cmdAyala Beker1-8/+32
The API was reduced to include only knowledge currently needed by the FW scan logic, the rest is legacy. Support the new, reduced version. Using the old API with newer firmwares (starting from iwlwifi-*-50.ucode, which implements and requires the new API version) causes an assertion failure similar to this one: [ 2.854505] iwlwifi 0000:00:14.3: 0x20000038 | BAD_COMMAND Signed-off-by: Ayala Beker <[email protected]> Signed-off-by: Luca Coelho <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

Remove the "apply points" mechanism as preparation for the changed debug API where this is now a "time point" instead. Use a new API across the code at the trigger points ("time points"), but don't yet implement it since that requires some more preparation.
