2012-02-22iwlegacy: use writeb,writel,readl directlyStanislaw Gruszka
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: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-22iwlegacy: cleanup/fix memory barriersStanislaw Gruszka
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.

2012-02-22iwlegacy: dump stack when fail to gain access to the deviceStanislaw Gruszka
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: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-22rtlwifi: rtl8192se firmware load can overflow target bufferTim Gardner
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.
