  • 2aa8f5d63   libata: only call ->done once all per-tag ressources are released ... Browse Code »

    When calling ->done before releasing resources we could run into a
    race where the SCSI midlayer sends another command and races with
    the resources beeing manipulated. For libata this can't currently
    happen as synchronization happens at a higher level, but I'd still
    like to fix it to future proof libata and to avoid copy & paste
    into SCSI drivers where this pattern has led to reproducible crashes.

  • 8a3e33cf9   ata: ahci: find eSATA ports and flag them as removable ... Browse Code »

    If the AHCI ports' HPCP or ESP bits are set, the port
    should be considered external (e.g. eSATA) and is marked
    as removable. Userspace tools like udisks then treat it
    like an usb drive.

    With this patch applied, when I plug a drive into the esata port,
    KDE pops up a window asking what to do with the drives(s), just
    like it does for any random USB stick.

    Removability is indicated to the upper layers by way of the
    SCSI RMB bit, as I haven't found another way to signal
    userspace to treat a sata disk like any usb stick.

  • 469eabb3a   ata: pata_macio: Fix module autoload for OF platform driver ... Browse Code »

    This platform driver has a OF device ID table but the OF module
    alias information is not created so module autoloading won't work.

    This patch adds the missing MODULE_DEVICE_TABLE() for OF to export
    that information so modules have the correct aliases built-in and
    autoloading works correctly.

    The PXA architecture was offered a slave dmaengine support. As a
    consequence the direct DMA registers are progressively replaced by
    dmaengine support.

    This makes the pata_pxa change, which brings this driver to almost a
    generic ATA 40-wires driver relying on dmaengine for transfers.

  • ecfb45985   ahci: added a new driver for supporting Freescale AHCI sata ... Browse Code »

    Currently Freescale QorIQ series SATA is supported by ahci_platform
    driver. Some SoC specific settings have been put in uboot. So whether
    SATA works or not heavily depends on uboot.
    This patch will add a new driver to support QorIQ sata which removes
    the dependency on any other boot loader.
    Freescale QorIQ series sata, like ls1021a ls2085a ls1043a, is
    compatible with serial ATA 3.0 and AHCI 1.3 specification.

    ("ahci: added support for Freescale AHCI sata")

    The reverted patch added Freescale QorIQ AHCI sata support to
    ahci_platform driver though, but it left SoC specific settings to uboot.
    It leads to QorIQ sata heavily depending on uboot. In order to removing
    the dependency we first revert the old patch and then will add a new driver
    for QorIQ SATA.
    Since there are no LS* platforms that have been upstreamed, So
    the revert would not break anything exists.

    Pull MIPS updates from Ralf Baechle:
    "This is the main pull request for 4.3 for MIPS. Here's the summary:

    Three fixes that didn't make 4.2-stable:

    - a -Os build might compile the kernel using the MIPS16 instruction
    set but the R2 optimized inline functions in are
    implemented using 32-bit wide instructions which is invalid.

    - a build error in pgtable-bits.h for a particular kernel
    configuration.

    - accessing registers of the CM GCR might have been compiled to use
    64 bit accesses but these registers are onl 32 bit wide.

    And also a few new bits:

    - move the ATH79 GPIO driver to drivers/gpio

    - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
    change ATH79 accordingly.

    - fix definition of pgprot_writecombine

    - add an implementation of dma_map_ops.mmap

    - fix alignment of quiet build output for vmlinuz link

    - BCM47xx: Use kmemdup rather than duplicating its implementation

    - Netlogic: Fix 0x0x prefixes of constants.

    - merge Bjorn Helgaas' series to remove most of the weak keywords
    from function declarations.

    - CP0 and CP1 registers are best considered treated as unsigned
    values to avoid large values from becoming negative values.

    - improve support for the MIPS GIC timer.

    - enable common clock framework for Malta and SEAD3.

    - a number of improvments and fixes to dump_tlb().

    - document the MIPS TLB dump functionality in Magic SysRq.

    - Cavium Octeon CN68XX improvments.

    - NetLogic improvments.

    - irq: Use access helper irq_data_get_affinity_mask.

    - handle MSA unaligned accesses.

    - a number of R6-related math-emu fixes.

    - support for I6400.

    - improvments to MSA support.

    - add uprobes support.

    - move from deprecated __initcall to arch_initcall.

    - remove finish_arch_switch().

    - IRQ cleanups by Thomas Gleixner.

    - migrate to new 'set-state' interface.

    - random small cleanups"

  • 832f5dacf   MIPS: Remove all the uses of custom gpio.h ... Browse Code »

    Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS
    machines, and each machine type provides its own gpio.h. However
    only a handful really implement the GPIO API, most just forward
    everythings to gpiolib.

    The Alchemy machine is notable as it provides a system to allow
    implementing the GPIO API at the board level. But it is not used by
    any board currently supported, so it can also be removed.

    For most machine types we can just remove the custom gpio.h, as well
    as the custom wrappers if some exists. Some of the code found in
    the wrappers must be moved to the respective GPIO driver.

    A few more fixes are need in some drivers as they rely on linux/gpio.h
    to provides some machine specific definitions, or used asm/gpio.h
    instead of linux/gpio.h for the gpio API.

  • 91f15fb30   PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI ... Browse Code »

    On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at
    function 1 doesn't work if it is powered on before the SATA controller at
    function 0. The result is that PATA doesn't work after resume, and we
    print messages like this:

    pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3
    irq 17: nobody cared (try booting with the "irqpoll" option)

    Async resume was introduced in v3.15 by 76569faa62c4 ("PM / sleep:
    Asynchronous threads for resume_noirq"). Prior to that, we powered on
    the functions in order, so this problem shouldn't happen.

    e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361")
    solved the problem for JMicron 361 and 363 devices. With async suspend
    disabled, we always power on function 0 before function 1.

    Barto then reported the same problem with a JMicron 368 (see comment #57 in
    the bugzilla).

    Rather than extending the blacklist piecemeal, disable async suspend for
    all JMicron multi-function SATA/PATA/AHCI devices.

    This quirk could stay in the ahci and pata_jmicron drivers, but it's likely
    the problem will occur even if pata_jmicron isn't loaded until after the
    suspend/resume. Making it a PCI quirk ensures that we'll preserve the
    power-on order even if the drivers aren't loaded.

    led to silent data corruption on some devices. A new quirk is
    added to restore the old size limit for the reported device. If it
    gets reported on more devices, we might have to consider restoring
    the restriction for ATA devices by default.

    - There finally is a SSD which is confirmed to cause data corruption
    on TRIM regardless of which flavor is used. A new quirk is added
    and the device is blacklisted

    A new Micron drive was just announced, once again recycling the first
    part of the model string. Add an underscore to the M510/M550 pattern to
    avoid picking up the new DC drive.

    I have a ST4000DM000 disk. If Linux is booted while the disk is spun down,
    the command that sets transfer mode causes the disk to spin up. The
    spin-up takes longer than the default 5s timeout, so the command fails and
    timeout is reported.

    Fix this by increasing the timeout to 15s, which is enough for the disk to
    spin up.

    Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db66e08),
    data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family)
    SATA controller. This patch will allow the driver to limit max_sectors as before

    # cat /sys/block/sdb/queue/max_sectors_kb
    512

    I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2
    before seeing corruption, but seems safer to use previous limit. Without this
    patch max_sectors_kb will be 32767.

    tj: Minor comment update.
