2017-10-06iwlwifi: acpi: remove a couple of unnecessary ifdefsLuca Coelho
Some of the #ifdef CONFIG_ACPI are not needed anymore, so they can be removed. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-10-06iwlwifi: acpi: make iwl_get_bios_mcc() use the common acpi functionsLuca Coelho
The way iwl_get_bios_mcc() gets the WiFi package and checks for its integrity is almost identical to the new iwl_acpi_get_wifi_pkg() function. Instead of having duplicate code, convert it to use the common code. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-10-06iwlwifi: acpi: use iwl_acpi_get_wifi_pkg when reading reading SPLCLuca Coelho
Instead of finding the wifi package with its own code, we can reuse the new iwl_acpi_get_wifi_pkg() function when reading the default power limit from SPLC. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-10-06iwlwifi: acpi: generalize iwl_mvm_sar_find_wifi_pkg()Luca Coelho
Move this function to acpi.c, renaming it to iwl_acpi_get_wifi_pkg(), because it can also be used with other methods (i.e. SPLC and WRDD). Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-10-06iwlwifi: acpi: move ACPI-related definitions to acpi.hLuca Coelho
The ACPI table size definitions were spread around the different files that used them. Move them all to a common place. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-10-06iwlwifi: acpi: move ACPI method definitions to acpi.hLuca Coelho
Instead of defining each method where they are used and re-defining WIFI_DOMAIN in each one of them, move all the definitions to a central place and define the domain only a single time. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-10-06iwlwifi: acpi: add common code to read from ACPILuca Coelho
There are many places where the same process of invoking a method from ACPI is used, causing a lot of duplicate code. To improve this, introduce a new function to get an ACPI object by invoking an ACPI method that can be reused. Additionally, since this function needs to be called when we only have the trans, the opmode or the device, introduce a new debug macro that gets the device as a parameter so it can be used in the new function.

2017-10-06iwlwifi: pcie: dump registers when HW becomes inaccessibleRajat Jain
We conclude the HW became inaccessible when we timeout waiting for a bit to be set in a memory mapped register (CSR_GP_CNTRL). This conclusion may not be true because the bit may not get set due to: - a firmware issue - a driver issue - a PCI bus issue - a platform issue There are a lot of such reports with really no good debug information beyond this message to help us. Add some debug information and attempt to dump the different register spaces at such a failure: * Dump some configuration space of device - this will tell us if something very basic is broken in the PCIe bus (so that configuration accesses are failing). If this works, the PCIe bus seems OK. If this does not work, it is definitely an PCIe issue. * Dump some memory mapped registers - if we're reading some sane'ish values, this will tell us that the PCIe bus is OK, but may be a firmware / driver issue. If this does not work, it may be a PCI configuration issue or a driver/firmware issue. * Dump parent and device's AER registers, will give us some straws to chew on.

2017-10-06iwlwifi: mvm: don't send identical PHY_CTXT_CMDEmmanuel Grumbach
When we have an AP which supports HT and a single HT station is connected, we change the min_width from NL80211_CHAN_WIDTH_20_NOHT to NL80211_CHAN_WIDTH_20. This of course has no implication on the channel width but still sends a command to the firmware. Remember the last width that was sent and refrain from sending unnecessary commands to the firmware. Sending a PHY_CTXT_CMD to the firmware has a cost since it recalculates the presence on the medium and because of that it closes the transmit queues for a short while.

2017-10-02brcmfmac: Avoid possible out-of-bounds readKevin Cernekee
In brcmf_p2p_notify_rx_mgmt_p2p_probereq(), chanspec is assigned before the length of rxframe is validated. This could lead to uninitialized data being accessed (but not printed). Since we already have a perfectly good endian-swapped copy of rxframe->chanspec in ch.chspec, and ch.chspec is not modified by decchspec(), avoid the extra assignment and use ch.chspec in the debug print.

In routine rtl92ee_set_fw_rsvdpagepkt(), the driver allocates an skb, but never calls rtl_cmd_send_packet(), which will free the buffer. All other rtlwifi drivers perform this operation correctly. This problem has been in the driver since it was included in the kernel. Fortunately, each firmware load only leaks 4 buffers, which likely explains why it has not previously been detected.
