2019-08-06rtw88: add BT co-existence supportYan-Hsuan Chuang
Both RTL8822BE/RTL8822CE are WiFi + BT combo chips. Since WiFi and BT use 2.4GHz to transmit, it is important to make sure they run concurrently without interfering each other. To achieve this, WiFi driver requires a mechanism to collaborate with BT, whether they share the antenna(s) or not. The final decision made by the co-existence mechanism is to choose a proper strategy, or called "tdma/table", and inform either firmware or hardware of the strategy. To choose a strategy, co-existence mechanism needs to have enough information from WiFi and BT. BT information is provided through firmware C2H. The contents describe the current status of BT, such as if BT is connected or is idle, or the profile that is being used. WiFi information can be provided by WiFi itself. The WiFi driver will call various of "notify" functions each time the state of WiFi changed, such as WiFi is going to switch channel or is connected. Also WiFi driver can know if it shares antenna with BT by reading efuse content. Antenna configuration of the module will finally get a different strategy. Upon receiving any information from WiFi or BT, the WiFi driver will run the co-existence mechanism immediately. It will set the RF antenna configuration according to the strategy through the TDMA H2C to firmware and a hardware table. Based on the tdma/table, WiFi + BT should work with each other, and having a better user experience.

2019-08-06rtlwifi: rtl8188ee: Convert inline routines to little-endian wordsLarry Finger
In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. The macro that cleared a descriptor has now been converted into an inline routine.

2019-08-06rtlwifi: rtl8188ee: Convert macros that set descriptorLarry Finger
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-08-06rtlwifi: rtl88188ee: Replace local bit manipulation macrosLarry Finger
This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities.

We're just trusting that these tables are of the right dimensions, when we could do better by just using the struct directly. Let's expose the struct txpwr_lmt_cfg_pair instead. The table changes were made by using some Vim macros, so that should help prevent any translation mistakes along the way.

2019-07-24rtw88: pci: Rearrange the memory usage for skb in RX ISRJian-Hong Pan
Testing with RTL8822BE hardware, when available memory is low, we frequently see a kernel panic and system freeze.

At this point, the RX ring may continue referencing an old skb which was already handed off to ieee80211_rx_irqsafe(). When it comes to be used again, bad things happen. This patch allocates a new, data-sized skb first in RX ISR. After copying the data in, we pass it to the upper layers. However, if skb allocation fails, we effectively drop the frame. In both cases, the original, full size ring skb is reused. In addition, to fixing the kernel crash, the RX routine should now generally behave better under low memory conditions.

2019-07-24rtl8xxxu: Fix wifi low signal strength issue of RTL8723BUChris Chiu
The WiFi tx power of RTL8723BU is extremely low after booting. So the WiFi scan gives very limited AP list and it always fails to connect to the selected AP. This module only supports 1x1 antenna and the antenna is switched to bluetooth due to some incorrect register settings. Compare with the vendor driver https://github.com/lwfinger/rtl8723bu, we realized that the 8723bu's enable_rf() does the same thing as rtw_btcoex_HAL_Initialize() in vendor driver. And it by default sets the antenna path to BTC_ANT_PATH_BT which we verified it's the cause of the wifi weak tx power. The vendor driver will set the antenna path to BTC_ANT_PATH_PTA in the consequent btcoexist mechanism, by the function halbtc8723b1ant_PsTdma. This commit hand over the antenna control to PTA(Packet Traffic Arbitration), which compares the weight of bluetooth/wifi traffic then determine whether to continue current wifi traffic or not. After PTA take control, The wifi signal will be back to normal and the bluetooth scan can also work at the same time. However, the btcoexist still needs to be handled under different circumstances. If there's a BT connection established, the wifi still fails to connect until BT disconnected. Signed-off-by: Chris Chiu <chiu@endlessm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-07-12scripts/spelling.txt: drop "sepc" from the misspelling listPaul Walmsley
The RISC-V architecture has a register named the "Supervisor Exception Program Counter", or "sepc". This abbreviation triggers checkpatch.pl's misspelling detector, resulting in noise in the checkpatch output. The risk that this noise could cause more useful warnings to be missed seems to outweigh the harm of an occasional misspelling of "spec". Thus drop the "sepc" entry from the misspelling list.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx Pull still more SPDX updates from Greg KH: "Another round of SPDX updates for 5.2-rc6 Here is what I am guessing is going to be the last "big" SPDX update for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that were "easy" to determine by pattern matching. The ones after this are going to be a bit more difficult and the people on the spdx list will be discussing them on a case-by-case basis now. Another 5000+ files are fixed up, so our overall totals are: Files checked: 64545 Files with SPDX: 45529 Compared to the 5.1 kernel which was: Files checked: 63848 Files with SPDX: 22576 This is a huge improvement. Also, we deleted another 20000 lines of boilerplate license crud, always nice to see in a diffstat" * tag 'spdx-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: (65 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 507 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 506 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 505 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 504 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 503 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 502 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 501 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 500 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 499 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 498 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 497 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 496 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 495 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 491 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 490 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 489 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 488 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 487 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 486 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 485 ...
