  • 9ac1c3200   crypto: ux500 - do not build with -O0 ... Browse Code »

    The ARM allmodconfig build currently warngs because of the
    ux500 crypto driver not working well with the jump label
    implementation that we started using for dynamic debug, which
    breaks building with 'gcc -O0':

    asm_volatile_goto("1:\n\t"

    Turning off compiler optimizations has never really been supported
    here, and it's only used when debugging the driver. I have not found
    a good reason for doing this here, other than a misguided attempt
    to produce more readable assembly output. Also, the driver is only
    used in obsolete hardware that almost certainly nobody will spend
    time debugging any more.

    This just removes the -O0 flag from the compiler options.

  • 596103cf8   crypto: drivers - Fix Kconfig selects ... Browse Code »

    This patch fixes a number of problems in crypto driver Kconfig
    entries:

    1. Select BLKCIPHER instead of BLKCIPHER2. The latter is internal
    and should not be used outside of the crypto API itself.
    2. Do not select ALGAPI unless you use a legacy type like
    CRYPTO_ALG_TYPE_CIPHER.
    3. Select the algorithm type that you are implementing, e.g., AEAD.
    4. Do not select generic C code such as CBC/ECB unless you use them
    as a fallback.
    5. Remove default n since that is the default default.

  • e1f8859ee   crypto: ux500 - make interrupt mode plausible ... Browse Code »

    The interrupt handler in the ux500 crypto driver has an obviously
    incorrect way to access the data buffer, which for a while has
    caused this build warning:

    ../ux500/cryp/cryp_core.c: In function 'cryp_interrupt_handler':
    ../ux500/cryp/cryp_core.c:234:5: warning: passing argument 1 of '__fswab32' makes integer from pointer without a cast [enabled by default]
    writel_relaxed(ctx->indata,
    ^
    In file included from ../include/linux/swab.h:4:0,
    from ../include/uapi/linux/byteorder/big_endian.h:12,
    from ../include/linux/byteorder/big_endian.h:4,
    from ../arch/arm/include/uapi/asm/byteorder.h:19,
    from ../include/asm-generic/bitops/le.h:5,
    from ../arch/arm/include/asm/bitops.h:340,
    from ../include/linux/bitops.h:33,
    from ../include/linux/kernel.h:10,
    from ../include/linux/clk.h:16,
    from ../drivers/crypto/ux500/cryp/cryp_core.c:12:
    ../include/uapi/linux/swab.h:57:119: note: expected '__u32' but argument is of type 'const u8 *'
    static inline __attribute_const__ __u32 __fswab32(__u32 val)

    There are at least two, possibly three problems here:
    a) when writing into the FIFO, we copy the pointer rather than the
    actual data we want to give to the hardware
    b) the data pointer is an array of 8-bit values, while the FIFO
    is 32-bit wide, so both the read and write access fail to do
    a proper type conversion
    c) This seems incorrect for big-endian kernels, on which we need to
    byte-swap any register access, but not normally FIFO accesses,
    at least the DMA case doesn't do it either.

    This converts the bogus loop to use the same readsl/writesl pair
    that we use for the two other modes (DMA and polling). This is
    more efficient and consistent, and probably correct for endianess.

    The bug has existed since the driver was first merged, and was
    probably never detected because nobody tried to use interrupt mode.
    It might make sense to backport this fix to stable kernels, depending
    on how the crypto maintainers feel about that.

    Pull ARM SoC driver specific changes from Arnd Bergmann:
    "These changes are all driver specific and cross over between arm-soc
    contents and some other subsystem, in these cases cpufreq, crypto,
    dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
    these changes merged through arm-soc.

    As we proceed to untangle the dependencies between platform code and
    driver code, the amount of changes in this category is fortunately
    shrinking, for 3.11 we have 16 branches here and 101 non-merge
    changesets, the majority of which are for the stedma40 dma engine
    driver used in the ux500 platform. Cleaning up that code touches
    multiple subsystems, but gets rid of the dependency in the end.

    The mailbox code moved out from mach-omap2 to drivers/mailbox is an
    intermediate step and is still omap specific at the moment. Patches
    exist to generalize the subsystem and add other drivers with the same
    API, but those did not make it for 3.11."
