2015-10-14rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger1-2599/+0
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.

2015-05-26rtlwifi: Remove the clear interrupt routine from all driversVincent Fann1-16/+0
Several of these drivers have there TX randomly blocked for 3~5 seconds while measuring tx throughput (iperf). The root couse happens in rtl_pci_flush(). The function uses a while-loop to wait for TX queue length to decrease to 0. The TX queue length counts the number of packets that are queued in the driver. The driver relys on the TX OK interrupt to return skb and reduce TX queue length. The interrupt subroutine disables interupts, reads the interrupt registers, and then clears the registers in the beginning of _rtl_pci_interrupt(). After all interupts process are finished, the driver invokes enable_interrupt() to enable interupts. This behavior is normal for an interrupt subroutine. But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in unterminated while-loop. This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.

2015-03-20rtl8188ee: fix build break due to missing rtl_hal_pwrseqcmdparsing definitionJeff Layton1-0/+1
I've been getting this error when building mainline kernels using Fedora's config files: drivers/net/wireless/rtlwifi/rtl8188ee/hw.c: In function ‘_rtl88ee_init_mac’: drivers/net/wireless/rtlwifi/rtl8188ee/hw.c:853:2: error: implicit declaration of function ‘rtl_hal_pwrseqcmdparsing’ [-Werror=implicit-function-declaration] if (!rtl_hal_pwrseqcmdparsing(rtlpriv, PWR_CUT_ALL_MSK, ^ cc1: some warnings being treated as errors scripts/Makefile.build:258: recipe for target 'drivers/net/wireless/rtlwifi/rtl8188ee/hw.o' failed I'm not sure if this is the correct fix, but it does seem to allow the build to complete. I suspect that this was broken by commit 34ed780a6afc (rtlwifi: Fix problems with building an allyesconfig). Most of the files that removed the include of pwrseqcmd.h, added one for ../pwrseqcmd.h. The rtl8188ee driver had it removed it but didn't add the include of the file in the parent directory.

2014-09-27rtlwifi: rtl8188ee: Update driver to match Realtek release of 06282014Larry Finger1-582/+676
Not only does this patch update the driver to match the latest Realtek release, it is an important step in getting the internal code source at Realtek to match the code in the kernel. The primary reason for this is to make it easier for Realtek to maintain the kernel source without requiring an intermediate like me. In this process of merging the two source repositories, there are a lot of changes in both, and this commit is rather large.

2014-02-25rtlwifi: avoid accessing RCR directlyPeter Wu1-2/+3
The rtl*_set_check_bssid functions are mostly the same, but access the RCR register in different ways. Use the get_hw_reg abstraction layer (which reads rtlpci->receive_config for PCI devices and mac->rx_conf for USB). There is no functional change for cases where receive_config was accessed directly. For rtl8192ce, there is still no change because nothing modifies REG_RCR or receive_config. For rtl8192cu, it now also applies changes to rx_conf from configure_filter, but that can be considered a bug which is fixed later.
