* mac80211: ath10k: search all IEs for variant before falling backChristian Lamparter2018-03-142-0/+237
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the patch that was posted to ath10k-devel ML: <https://patchwork.kernel.org/patch/10233491/> |From: Thomas Hebb <tommyhebb@gmail.com> |Subject: [PATCH] ath10k: search all IEs for variant before falling back |Date: Wed, 21 Feb 2018 11:43:39 -0500 |[...] |This patch fixes the issue by first searching the entire file for the ID |with variant, and searching for the fallback ID only if that search |fails. It also includes some code cleanup in the area, as |ath10k_core_fetch_board_data_api_n() no longer does its own string |mangling to remove the variant from an ID, instead leaving that job to a |new flag passed to ath10k_core_create_board_name(). | |I've tested this patch on a QCA4019 and verified that the driver behaves |correctly for 1) both fallback and variant BDFs present, 2) only fallback |BDF present, and 3) no matching BDFs present. | |Fixes: 1657b8f84ed9 ("ath10k: search SMBIOS for OEM board file extension") |Signed-off-by: Thomas Hebb <tommyhebb@gmail.com> Note: 937-ath10k-calibration-variant.patch has been reassigned a new 081 number, as it now ships with upstream.... But also because this patch requires the change in ath10k_core_create_board_name(). Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

| | | | | | | | | Revert upstream commit 1bd773c077de "wireless: set correct mandatory rate flags", as it breaks 11s interoperability: nodes can only associate when neither or both have this patch.

* ath9k, ath10k(-ct): move spectral scan support under a separate config symbolMatthias Schiffer2018-01-132-0/+194
| | | | | | | | | | | | | Backport patches that separate spectral scan support from general debugfs support of ath9k/ath10k; this allows to remove the dependency on KERNEL_RELAY from these driver packages even with debugfs enabled and avoids the memory footprint of the relay buffers allocated by ath9k/ath10k even when they aren't used at all. The KERNEL_RELAY dependency is moved to a new config symbol that enables spectral scan support in these drivers. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
* mac80211: ath10k: search DT for BDF variant infoSven Eckelmann2018-01-131-0/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified on QCA4019 using bus, bmi-chip-id and bmi-board-id. The problem, however, can occur when the (default) board data file cannot fulfill the vendor requirements and it is necessary to use a different board data file. This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8. Something similar has to be provided for systems without SMBIOS but with device trees. No solution was specified by QCA and therefore a new one has to be found for ath10k. The device tree requires addition strings to define the variant name wifi@a000000 { status = "okay"; qcom,ath10k-calibration-variant = "RT-AC58U"; }; wifi@a800000 { status = "okay"; qcom,ath10k-calibration-variant = "RT-AC58U"; }; This would create the boarddata identifiers for the board-2.bin search * bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U * bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U Signed-off-by: Sven Eckelmann <sven.eckelmann@open-mesh.com>

* mac80211: update to backports-4.14-rc2Hauke Mehrtens2017-10-01142-7093/+317
| | | | | | | | | | | | | | | | | | | | This updates mac80211 to backprots-4.14-rc2. This was compile and runtime tested with ath9k, ath10k and b43 with multiple stations and ieee80211w and in different scenarios by many other people. To create the backports-4.14-rc2-1.tar.xz use this repository: https://git.kernel.org/pub/scm/linux/kernel/git/backports/backports.git from tag v4.14-rc2-1 Then run this: ./gentree.py --git-revision v4.14-rc2 --clean <path to linux repo> ../backports-4.14-rc2-1 This also adapts the ath10k-ct and mt76 driver to the changed cfg80211 APIs and syncs the nl80211.h file in iw with the new version from backports-4.14-rc2.

* mac80211: add dev_coredumpm() functionHauke Mehrtens2017-09-171-0/+156
| | | | | | | | | | | | | | | | dev_coredumpm() was added with kernel 4.7, but it is used by iwlwifi. When the dev coredump framework form compat-wireless is used this is not a problem because it already contains this, but this is deactivated if the build system finds out that it is already included in the kernel we compile against. This option was now activated by the bluetooth driver btmrvl. Having dev coredump in the kernel adds about 400 bytes to the lzma compressed kernel for brcm47xx. This is copied from a more recent backports version to add the dev_coredumpm() function when the internal core devdump is not used.

| | | | | | | | | | | | The upstream ath10k driver disables the intermediate softqueues for some devices. This patch reverts that behaviour and always enables the softqueues (and associated bufferbloat fixes). We have had reports of people running this with good results: https://lists.bufferbloat.net/pipermail/make-wifi-fast/2017-September/001497.html This also refreshes mac80211 patches.
