2021-04-21rtlwifi: implement set_tim by update beacon contentPing-Ke Shih
Once beacon content is changed, we update the content to wifi card by send_beacon_frame(). Then, STA with PS can wake up properly to receive its packets. Since we update beacon content to PCI wifi devices every beacon interval, the only one usb device, 8192CU, needs to update beacon content when mac80211 calling set_tim. Reported-by: Maciej S.

2021-04-17rtlwifi: Simplify locking of a skb list accessesChristophe JAILLET
The 'c2hcmd_lock' spinlock is only used to protect some __skb_queue_tail() and __skb_dequeue() calls. Use the lock provided in the skb itself and call skb_queue_tail() and skb_dequeue(). These functions already include the correct locking.

2020-09-29net: rtlwifi: Remove void* casts related to delayed workSebastian Andrzej Siewior
INIT_DELAYED_WORK() takes two arguments: A pointer to the delayed work and a function reference for the callback. The rtl code casts all function references to (void *) because the callbacks in use are not matching the required function signature. That's error prone and bad pratice. Some of the callback functions are also global, but only used in a single file. Clean the mess up by: - Adding the proper arguments to the callback functions and using them in the container_of() constructs correctly which removes the hideous container_of_dwork_rtl() macro as well. - Removing the type cast at the initializers - Making the unnecessary global functions static Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Kalle Valo <kvalo@codeaurora.org> Signed-off-by: David S.

2020-03-23wireless: realtek: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

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.

2019-05-28rtlwifi: rtl8821ae: 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.

2018-05-29rtlwifi: support accurate nullfunc frame tx ack reportTzu-En Huang
In order to realize the keep-alive mechanism in mac80211 stack, reporting accurate tx ack status for nullfunc frame is added in this commit. If current frame is nullfunc frame, we ask firmware to report by filling TX report bit in TX descriptor. After this frame DMA done, TX interrupt is triggered but TX status is unknown at this moment, so enqueue this skb into tx_report->queue. Finally, C2H report will be received if the frame is transmitted successfully or retried over, and then we report to mac80211 with IEEE80211_TX_STAT_ACK flag only if it's successful. Otherwise, if failure or timeout (one second), we report to mac80211 without this flag.

2018-04-24rtlwifi: cleanup 8723be ant_sel definitionPing-Ke Shih
Some HP laptops have only a single wifi antenna. This would not be a problem except that they were shipped with an incorrectly encoded EFUSE. It should have been possible to open the computer and transfer the antenna connection to the other terminal except that such action might void the warranty, and moving the antenna broke the Windows driver. The fix was to add a module option that would override the EFUSE encoding. That was done with commit c18d8f509571 ("rtlwifi: rtl8723be: Add antenna select module parameter"). There was still a problem with Bluetooth coexistence, which was addressed with commit baa170229095 ("rtlwifi: btcoexist: Implement antenna selection"). There were still problems, thus there were commit 0ff78adeef11 ("rtlwifi: rtl8723be: fix ant_sel code") and commit 6d6226928369 ("rtlwifi: btcoexist: Fix antenna selection code"). Despite all these attempts at fixing the problem, the code is not yet right. A proper fix is important as there are now instances of laptops having RTL8723DE chips with the same problem. The module parameter ant_sel is used to control antenna number and path. At present enum ANT_{X2,X1} is used to define the antenna number, but this choice is not intuitive, thus change to a new enum ANT_{MAIN,AUX} to make it more readable. This change showed examples where incorrect values were used. It was also possible to remove a workaround in halbtcoutsrc.c. The experimental results with single antenna connected to specific path are now as follows: ant_sel ANT_MAIN(#1) ANT_AUX(#2) 0 -8 -62 1 -62 -10 2 -6 -60 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Fixes: c18d8f509571 ("rtlwifi: rtl8723be: Add antenna select module parameter") Fixes: baa170229095 ("rtlwifi: btcoexist: Implement antenna selection") Fixes: 0ff78adeef11 ("rtlwifi: rtl8723be: fix ant_sel code") Fixes: 6d6226928369 ("rtlwifi: btcoexist: Fix antenna selection code") Cc: Stable <stable@vger.kernel.org> # 4.7+ Reviewed-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-02-07rtlwifi: rtl8821ae: Fix connection lost problem correctlyLarry Finger
There has been a coding error in rtl8821ae since it was first introduced, namely that an 8-bit register was read using a 16-bit read in _rtl8821ae_dbi_read(). This error was fixed with commit 40b368af4b75 ("rtlwifi: Fix alignment issues"); however, this change led to instability in the connection. To restore stability, this change was reverted in commit b8b8b16352cd ("rtlwifi: rtl8821ae: Fix connection lost problem"). Unfortunately, the unaligned access causes machine checks in ARM architecture, and we were finally forced to find the actual cause of the problem on x86 platforms. Following a suggestion from Pkshih <pkshih@realtek.com>, it was found that increasing the ASPM L1 latency from 0 to 7 fixed the instability. This parameter was varied to see if a smaller value would work; however, it appears that 7 is the safest value. A new symbol is defined for this quantity, thus it can be easily changed if necessary.

Enter/leavel IPS and LPS are large critical section, and they can't use sleep function because running in atomic-context, which own a spin_lock. In commit ba9f93f82aba ("rtlwifi: Fix enter/exit power_save"), it moves LPS functions to thread-context, so this commit can simply change LPS's spin lock to mutex. Considering IPS functions, rtl_ips_nic_on() may be called by TX tasklet (softirq-context) that check whether packet is auth frame. Fortunately, current mac80211 will ask driver to leave IPS using op_config with changed flag IEEE80211_CONF_CHANGE_IDLE, before issuing auth frame, so IPS functions can run in thread-context and use mutex to protect critical section, too. Also, this commit removes some useless spin locks. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-01-08rtlwifi: Improve debugging by using debugfsPing-Ke Shih
Use debugfs to dump register and btcoex status, and also write registers and h2c. We create topdir in /sys/kernel/debug/rtlwifi/, and use the MAC address as subdirectory with several entries to dump mac_reg, bb_reg, rf_reg etc. An example is /sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/mac_0 This change permits examination of device registers in a dynamic manner, a feature not available with the current debug mechanism.

2017-12-07rtlwifi: Convert individual interrupt results to structLarry Finger
With the RTL8822BE and later devices, the number of interrupt vectors has grown from 2 to 4. At this point, saving and passing those vectors in a struct makes more sense than using individual scaler variables. In two of the drivers, code to process the second of the interrupt registers was included, but commented out. This patch removes those useless sections.

2017-11-08rtlwifi: drop unused ppsc->last_wakeup_timeArnd Bergmann
The calculation of ppsc->last_wakeup_time is not y2038-safe, but the variable is not used at all, so we can simply drop it. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-11-08rtlwifi: use ktime_get_real_seconds() for suspend timeArnd Bergmann
do_gettimeofday() is deprecated and slower than necessary for the purpose of reading the seconds. This changes rtl_op_suspend/resume to use ktime_get_real_seconds() instead, which is simpler and avoids confusion about whether it is y2038-safe or not.

2017-11-08rtlwifi: rtl_pci: Extend recognized interrupt parameters from two to four ISRPing-Ke Shih
8822be checks H2CQ by int_d, so we extend to four ISR. Also, irq_mask is extended to four.

TXOK in interrupt. With the RTL8822BE, an H2C tx queue is added to download FW and special data. This change implements the support code in rtl_pci.
