No need to pass the dbgfs_dir just to assign it to mvm. Assign to mvm and then call iwl_mvm_dbgfs_register. This is a preparation towards the addition of a delayed op_mode_start flow. This will allow to split the op_mode_start flow. Registration to debugfs must happen after we register to mac80211 and the registration to mac80211 will soon be delayed in certain cases. In order not to have to remember the debugfs_dir in a separate variable, just set it into the mvm structure so that it can be usable later. Declare mvm->debugfs_dir in the iwl_mvm structure even when IWLWIFI_DEBUGFS isn't enabled to simplify the source code. Signed-off-by:

All the actions that were taken after the registration can be taken before the registration to mac80211. This will help to defer part of the op_mode_mvm_start function to a later stage in case the device is not available. Signed-off-by:

BIOS provides RFI feature enable/disable state via WiFi DSM ACPI object. By default the feature should be disabled. The GUID for this feature is different from the one driver currently uses, so need to provide a set of new definitions. Signed-off-by:

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. Signed-off-by:

Remember that those pointers have been freed by setting them to NULL. Otherwise, we'd keep rxq pointing to random memory which would prevent us from trying to re-allocate the Rx resources if we call rx_alloc again. Also, propagate the allocation failure to the caller of iwl_pcie_nic_init so that we won't go further in the start flow. Signed-off-by:

The call to iwl_sar_geo_init() was moved to the end of the iwl_mvm_sar_geo_init() function, after the table revision is assigned to the FW command. But the revision is only known after iwl_sar_geo_init() is called, so we were always assigning zero to it. Fix that by moving the assignment code after the iwl_sar_geo_init() function is called.

Some change conflicts apparently cause a confusion between a local variable being used to send the PPAG command and the introduction of a union for this command. Most parts of the local command were never copied from the stored data, so the FW was getting garbage in the tables instead of getting valid values. Fix this by completely removing the local and using only the union that we have stored in fwrt. Signed-off-by:

When reading the PPAG table from ACPI, we should store everything in our fwrt structure, so it can be accessed later. But we had a local ppag_table variable in the function and were erroneously storing the enabled/disabled flag in it instead of storing it in the fwrt. Fix this by removing the local variable and storing everything directly in fwrt. Signed-off-by:

Luca Coelho authored
The value we receive from ACPI is a long long unsigned integer but the values should be treated as signed char. When comparing the received value with ACPI_PPAG_MIN_LB/HB, we were doing an unsigned comparison, so the negative value would actually be treated as a very high number. To solve this issue, assign the value to our table of s8's before making the comparison, so the value is already converted when we do so. Signed-off-by:

We were erroneously adding 3 extra values to the table size calculation, when we should actually add only a 2 (one for the domain type and one for the enabled/disabled flag). Fix this for both revisions we support. Signed-off-by:

The only thing we do touching the device in hard interrupt context is, at most, writing an interrupt ACK register, which isn't racing in with anything protected by the reg_lock. Thus, avoid disabling interrupts here for potentially long periods of time, particularly long periods have been observed with dumping of firmware memory (leading to lockup warnings on some devices.)

The ucode TLV data may be read-only and should be treated as const pointers, but currently a few code forcibly cast to the writable pointer unnecessarily. This gave developers a wrong impression as if it can be modified, resulting in crashing regressions already a couple of times. This patch adds the const prefix to those cast pointers, so that such attempt can be caught more easily in future. Signed-off-by:
