* rtlwifi: set proper udelay within rf_serial_readPing-Ke Shih2019-11-203-7/+4
| | | | | | | | | | | Since read RF register is an indirect access that hardware needs time to accomplish read action, but there's no ready bit, so delay is required to guarantee the read value is correct. After investigating internal documents, these delays are reduced as proper values.

* rtlwifi: rf_lock use non-irqsave spin_lockPing-Ke Shih2019-11-206-36/+24
| | | | | | | | | | | | | | | | | | | | | | rf_lock is used to protect RF register access, but they will not called from interrupt context, so *_irqsave version isn't necessary. Then, these delays don't affect IRQ services. The old code holds spin_lock_irqsave() that will be detected a long delay as below: kworker/-276 4d... 0us : _raw_spin_lock_irqsave kworker/-276 4d... 0us : rtl8723_phy_rf_serial_read <-rtl8723de_phy_set_rf_reg kworker/-276 4d... 1us : rtl8723_phy_query_bb_reg <-rtl8723_phy_rf_serial_read kworker/-276 4d... 3us : rtl8723_phy_set_bb_reg <-rtl8723_phy_rf_serial_read kworker/-276 4d... 4us : __const_udelay <-rtl8723_phy_rf_serial_read kworker/-276 4d... 4us!: delay_mwaitx <-rtl8723_phy_rf_serial_read kworker/-276 4d... 1004us : rtl8723_phy_set_bb_reg <-rtl8723_phy_rf_serial_read [...] Reported-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* rtlwifi: rtl8192de: Fix missing enable interrupt flagLarry Finger2019-11-141-4/+5
| | | | | | | | | | | | | | | In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for new drivers"), the flag that indicates that interrupts are enabled was never set. In addition, there are several places when enable/disable interrupts were commented out are restored. A sychronize_interrupts() call is removed.

| | | | | | | | | | | | | In commit 38506ecefab9 ("rtlwifi: rtl_pci: Start modification for new drivers"), a callback to get the RX buffer address was added to the PCI driver. Unfortunately, driver rtl8192de was not modified appropriately and the code runs into a WARN_ONCE() call. The use of an incorrect array is also fixed.

| | | | | | | | | | | | | | | | | | | | In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Several places where checkpatch.pl complains about a space after a cast and other warnings are fixed.

| | | | | | | | | | | | | | | | | | | | | | This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Add a new return value (that was previously considered invalid) to indicate that the driver is immediately ready for the session, and make drivers use it. The only drivers that remain different are the Intel ones as they need to negotiate more with the firmware.
