2018-07-26iwlwifi: pcie: support 2k rx buffersGolan Ben Ami1-0/+7
The smallest rb size supported today is 4k rx buffers. 22560 devices use 2k rxb's, so allow using 2k buffers. Signed-off-by: Golan Ben Ami <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-07-26iwlwifi: add module parameter to disable 802.11axLuca Coelho1-2/+2
Add a module parameter to disable 802.11ax features in supported devices. This is useful for testing or if there are interoperability issues with some APs. Signed-off-by: Luca Coelho <[email protected]>
2018-07-26iwlwifi: add support for IEEE802.11axLuca Coelho1-0/+103
Add support for the HE in the iwlwifi driver conforming with P802.11ax_D2.0. Signed-off-by: Luca Coelho <[email protected]>
2018-05-30iwlwifi: mvm: remove division by size of sizeof(struct ieee80211_wmm_rule)Colin Ian King1-2/+1
The subtraction of two struct ieee80211_wmm_rule pointers leaves a result that is automatically scaled down by the size of the size of pointed-to type, hence the division by sizeof(struct ieee80211_wmm_rule) is bogus and should be removed. Detected by CoverityScan, CID#1467777 ("Extra sizeof expression") Fixes: 77e30e10ee28 ("iwlwifi: mvm: query regdb for wmm rule if needed") Signed-off-by: Colin Ian King <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

To fix a conflict reported by Stephen Rothwell <[email protected]>: Today's linux-next merge of the wireless-drivers-next tree got a conflict in: drivers/net/wireless/intel/iwlwifi/iwl-nvm-parse.c between commit: 77e30e10ee28 ("iwlwifi: mvm: query regdb for wmm rule if needed") from the wireless-drivers tree and commits: 9c4f7d512740 ("iwlwifi: move all NVM parsing code to the common files") 4c625c564ba2 ("iwlwifi: get rid of fw/nvm.c") from the wireless-drivers-next tree.
2018-04-20iwlwifi: get rid of fw/nvm.cShaul Triebitz1-7/+104
There's already an opmode common file for nvm iwl-nvm-parse.c Move the content of fw/nvm.c to iwl-nvm-parse.c and delete fw/nvm.c. Signed-off-by: Shaul Triebitz <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-04-20iwlwifi: remove upper case letters in sku_capa_band_*_enableLuca Coelho1-3/+3
The sku_capa_band_24GHz_enable and sku_capa_band_52GHz_enable symbols cause checkpatch to complain whenever we use them. To prevent this, convert them to all lower case. Signed-off-by: Luca Coelho <[email protected]>
2018-04-20iwlwifi: use flags to denote modifiers for the channel mapsLuca Coelho1-9/+16
Instead of having a boolean for each modifier we need to handle in the channel maps, create a bitmask with flags that denote each modification. Signed-off-by: Luca Coelho <[email protected]>
2018-04-20iwlwifi: move all NVM parsing code to the common filesShaul Triebitz1-7/+207
Move all the NVM file handling code to iwl-nvm-parse.c where all this stuff belongs. This cleans up the MVM specific code and allows easier reuse by other opmodes if needed. Signed-off-by: Shaul Triebitz <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-04-09iwlwifi: mvm: query regdb for wmm rule if neededHaim Dreyfuss1-16/+95
Since our device is regulatory self managed it maintains its regulatory rules by its own. However the wmm_rules values can't be set by the device itself but only the indication about the need to set it. In case the device set wmm indication, proactively query the regulatory data base to get these values Signed-off-by: Haim Dreyfuss <[email protected]> Signed-off-by: Luca Coelho <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

Mark Brown reported that there are conflicts in iwlwifi between the two trees so fix those now.
2017-10-06iwlwifi: acpi: move function to get mcc into acpi codeLuca Coelho1-34/+0
The iwl_get_bios_mcc() function was in the iwl-nvm-parse.c file, but it has nothing to do with the NVM. Move it to fw/acpi.c and rename it to iwl_acpi_get_mcc(). Signed-off-by: Luca Coelho <[email protected]>
2017-10-06iwlwifi: acpi: make iwl_get_bios_mcc() use the common acpi functionsLuca Coelho1-47/+19
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 <[email protected]>
2017-10-06iwlwifi: acpi: move ACPI method definitions to acpi.hLuca Coelho1-6/+2
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 <[email protected]>
2017-10-06iwlwifi: acpi: add common code to read from ACPILuca Coelho1-29/+8
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: remove redundant reading from NVM fileChaya Rachel Ivgi1-7/+0
The driver reads xtal_calib from NVM file, but actually never uses it. This is only used in dvm driver. Signed-off-by: Chaya Rachel Ivgi <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-10-06iwlwifi: nvm: set the correct offsets to 3168 seriesChaya Rachel Ivgi1-16/+23
The driver currently handles two NVM formats, one for 7000 family and below, and one for 8000 family and above. The 3168 series uses something in between, so currently the driver uses incorrect offsets for it. Fix the incorrect offsets.

2017-10-06iwlwifi: nvm-parse: unify channel flags printingJohannes Berg1-59/+39
The current channel flags printing is very strange and messy, in LAR we sometimes print the channel number and sometimes the frequency, in both we print a calculated value (whether ad-hoc is supported or not) etc. Unify all this to * print the channel number, not the frequency * remove the band print (2.4/5.2 GHz, it's obvious) * remove the calculated Ad-Hoc print Doing all of this also gets the length of the string to a max of 101 characters, which is below the max of 110 for tracing, and thus avoids the warning that came up on certain channels with certain flag combinations.

2017-08-30iwlwifi: fix long debug printLiad Kaufman1-2/+7
There is a debug print that sometimes reaches over 110 chars, thus generating a warning in those cases. Split the print into two to prevent these cases.

2017-08-24Merge git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers.gitKalle Valo1-7/+10
Stephen Rothwell reported quite a few conflicts in iwlwifi between wireless-drivers and wireless-drivers-next. To avoid any problems later in other trees merge w-d to w-d-next to fix those conflicts early.
2017-08-18iwlwifi: use big-endian for the hw section of the nvmLuca Coelho1-6/+5
Unlike the other sections of the NVM, the hw section is in big-endian. To read a value from it, we had to cast it to __be16. Fix that by using __be16 * for the entire section. Signed-off-by: Luca Coelho <[email protected]>
2017-08-18iwlwifi: add workaround to disable wide channels in 5GHzLuca Coelho1-10/+52
The OTP in some SKUs have erroneously allowed 40MHz and 80MHz channels in the 5.2GHz band. The firmware has been modified to not allow this in those SKUs, so the driver needs to do the same otherwise the firmware will assert when we try to use it. Cc: [email protected] Signed-off-by: Luca Coelho <[email protected]>
2017-08-18iwlwifi: update channel flags parserLuca Coelho1-21/+30
There are some new flags in the channel flags that we don't know about. Also, the "WIDE" flag is very confusing, because it actually means 20MHz bandwidth, which is not very wide. Add the new flags and rename the confusing one. Signed-off-by: Luca Coelho <[email protected]>
2017-08-01iwlwifi: split the regulatory rules when the bandwidth flags require itEmmanuel Grumbach1-8/+11
When we create a regulatory domain out of an MCC notification, we need to make sure that all the channels in the rule have the exact same properties. The current code mixes channel 36 and 40 although 36 can be a control channel with HT40+ (36, 40) whereas 40 can't be a control channel with HT40+ since (40, 44) is invalid. Because of that, cfg80211 would allow to connect in 40MHz to APs that are configured to channel 40 HT40+ and that made our firmware assert. Fix this by checking the bandwidth flags before taking the decision if the rule should be split. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.

2017-06-23iwlwifi: mvm: print base HW address during initLuca Coelho1-0/+2
It's sometimes hard to find out which HW address the iwlwifi device is using, for instance when reading crouded sniffer logs. To make it easier, print out an info level message with the HW address as soon as we know it. Signed-off-by: Luca Coelho <[email protected]>
2017-06-05iwlwifi: cleanup references to 8000 family in NVM codeSara Sharon1-52/+43
NVM code is tightly coupled with 8000 family, while it really refers to extended NVM format introduced back then. Separate it to a configuration dependent boolean, and rename defines accordingly. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-04-25iwlwifi: adjust NVM parsing APIs for new a000 methodSara Sharon1-19/+13
In a000 devices we will get all nvm data from the firmware, and can save most of the parsing. Export two APIs that op mode will still use. Adjust API of init_sbands to be independent of NVM file structure so it can be used by op mode as well. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-09-19iwlwifi: move BIOS MCC retrieval to common codeArik Nemtsov1-0/+89

2016-09-19iwlwifi: check for valid ethernet address provided by OEMHaim Dreyfuss1-5/+10
In 9000 family products we added an option to let the OEM fuse the mac address via registers. If these registers are zeroed we use the OTP address instead. Make sure that the address provided by the OEM is valid and, if not, fall back to the OTP address as well.

2016-07-01iwlwifi: advertise maximal MPDU length when Rx MQ is supportedEmmanuel Grumbach1-0/+7
The new hardware that supports multiple queue also de-aggregates A-MSDUs. This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well. Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2016-05-10iwlwifi: consider VHT 160MHz while parsing NVMGregory Greenman1-3/+13
Devices belonging to 9000 family can support VHT 160MHz channel width, so need to consider it when configuring VHT capabilities. However, NVM file doesn't have a single bit specifying that 160MHz is supported. This patch turns on 160MHz support in VHT capabilities in case there's at least one channel supporting 160MHz.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg1-13/+13
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <[email protected]>
2016-03-09iwlwifi: add support for getting HW address from CSRSara Sharon1-21/+54
From 9000 family on, we need to get HW address from host CSR registers. OEM can override it by fusing the override registers - read those first, and if those are 0 - read the OTP registers instead. In addition - bail out if no valid mac address is present. Make it shared for all NICs. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2016-03-07iwlwifi: refactor the code that reads the MAC address from the NVMSara Sharon1-46/+51
It makes it slightly easier to follow. Pass the pointer to the transport which allows to read WFMP_MAC_ADDR_X register only when needed and to use IWL_ERR instead of the less commonly used IWL_ERR_DEV logger macro.

2016-02-01iwlwifi: treat iwl_parse_nvm_data() MAC addr as little endianJohannes Berg1-3/+4
The MAC address parameters passed to iwl_parse_nvm_data() are passed on to iwl_set_hw_address_family_8000() which treats them as little endian. Annotate them as such, and add the missing byte-swapping in mvm. While at it, add the MAC address to the error to make debugging issues with it easier.

2015-11-26iwlwifi: add support for 12K Receive BuffersEmmanuel Grumbach1-1/+12
802.11ac allows A-MSDU that can be up to 12KB long. Since an entire A-MSDU needs to fit into one single Receive Buffer (RB), add support for big RBs. Since this adds lots of pressure to the memory manager and significantly increase the true_size of the RX buffers, don't enable this by default. Signed-off-by: Emmanuel Grumbach <[email protected]>
2015-11-26iwlwifi: nvm: fix up phy section when reading itJohannes Berg1-14/+1
This is a workaround to an OTP bug. In Series 8000 1x1, the OTP 0xA052 defines 2x2 antenna configuration. This workaround overrides the decision based on HW id and on MIMO disabled bit which is correct in the OTP and set to disabled. This fixes the previous workaround "force 1x1 antenna in Series 8000".
