By swithing from our __raw_read and __raw_write functions to ioread32 and iowrite32, benchmarks on my desk with iperf went from 11MBps to 18.1MBps using the AHB bus on an EnGenius ECB3500 running OpenWRT. Signed-off-by:

The AP/GO mode API isn't very clearly defined, it has "set beacon" and "new beacon" etc. Modify the API to the following: * start AP -- all settings * change beacon -- new beacon data * stop AP -- stop AP mode operation This also reflects in the nl80211 API, rename the commands there correspondingly (but keep the old names for compatibility.) Overall, this makes it much clearer what's going on in the API. Kalle developed the ath6kl changes, I created the rest of the patch. Signed-off-by:

That change will save us some CPU cycles at run time. Having port-based I/O seems to be not possible for PCIe devices. Signed-off-by:

wmb(), rmb() are not needed when writel(), readl() are used as accessors for MMIO. We use them indirectly via iowrite32(), ioread32(). What is needed mmiowb(), for synchronizing writes coming from different CPUs on PCIe bridge (see in patch comments). This fortunately is not needed on x86, where mmiowb() is just defined as compiler barrier. As iwlegacy devices are most likely not used on anything other than x86, this is not so important fix.

Before we write to the device register always check if _il_grap_nic_access() was successful. Change type return type _il_grap_nic_access() to bool, and add likely()/unlikely() statements. Signed-off-by:

Print dump stack when the device is not responding. This should give some more clue about the reason of failure. Also change the message we print, since "MAC in deep sleep" is kinda confusing. On the way add unlikely(), as fail to gain NIC access is hmm ... unlikely. Signed-off-by:

Define RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE which represents the maximimum possible firmware file size. Use it in the definition of the buffer which receives the firmware file data. Set RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE closer to the actual size of the firmware file, e.g., 90000 (down from hard coded 164000). The current size of rtlwifi/rtl8192sefw.bin is 88856. Set max_fw_size to RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE for the size limit check. Fix the error case where max_fw_size is not cleared if the size limit check fails.

The sdio driver part uses firmware name brcmfmac.bin. With addition of usb this name is too generic. This patch renames the filename to brcmfmac-sdio.bin. Reviewed-by:

This patch extends the use of the brcmfmac driver with support for chipsets with a USB host interface. The first chipsets supported are the bcm43235, bcm43236, and bcm43238 for which firmware has been submitted. This driver change has been successfully built for x86, x86_64, ppc64, arm_le, and mips_be. It has been tested successfully on x86 and x86_64. Cc: M. Lambert <lambertm@westman.wave.ca> Reviewed-by:

This function is executed within irq context. The call spin_unlock_irq does enable interrupts which is not desired in the irq context. This patch replaces them using the spin_loc_irqsave and spin_unlock_irqrestore functions. Reviewed-by:

The bus state is updated in the sdio bus init function, but it is better to do it when the brcmf_bus_start() function is completed successfully. The brcmf_netdev_open() function will return -EAGAIN until the state is updated instead of calling brcmf_bus_start() to avoid reentering that function. Reviewed-by:

The fields bus_priv and drvr are defined as void pointer. It is preferred to have specific types for compiler type checking. To prepare for other bus types the bus_priv field is defined as a union containing the sdio bus private structure reference. Reviewed-by:

The A-MPDU code checked against a retry limit, but it was using the wrong variable to do so. This patch fixes this to assure proper retry mechanism. This problem had a side-effect causing the mac80211 flush callback to remain waiting forever as well.

The function wlc_phy_txpwrctrl_pwr_setup_nphy() does assign a local variable target_pwr_qtrdbm in several code paths, but in the end all code paths are coming to an assignment of that variable which does override all previous. So those early and redundant assignments have been removed. Reported-by:
