  • 576243b3f   PCI: pciehp: Allow exclusive userspace control of indicators ... Browse Code »

    PCIe hotplug supports optional Attention and Power Indicators, which are
    used internally by pciehp. Users can't control the Power Indicator, but
    they can control the Attention Indicator by writing to a sysfs "attention"
    file.

    The Slot Control register has two bits for each indicator, and the PCIe
    spec defines the encodings for each as (Reserved/On/Blinking/Off). For
    sysfs "attention" writes, pciehp_set_attention_status() maps into these
    encodings, so the only useful write values are 0 (Off), 1 (On), and 2
    (Blinking).

    However, some platforms use all four bits for platform-specific indicators,
    and they need to allow direct user control of them while preventing pciehp
    from using them at all.

    Add a "hotplug_user_indicators" flag to the pci_dev structure. When set,
    pciehp does not use either the Attention Indicator or the Power Indicator,
    and the low four bits (values 0x0 - 0xf) of sysfs "attention" write values
    are written directly to the Attention Indicator Control and Power Indicator
    Control fields.

  • 70626d883   PCI: pciehp: Make explicitly non-modular ... Browse Code »

    This code is not being built as a module by anyone:

    obj-$(CONFIG_HOTPLUG_PCI_PCIE) += pciehp.o
    pciehp-objs := pciehp_core.o \

    drivers/pci/pcie/Kconfig:config HOTPLUG_PCI_PCIE
    drivers/pci/pcie/Kconfig: bool "PCI Express Hotplug driver"

    Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(),
    etc., so that when reading the driver there is no doubt it is builtin-only.
    The information is preserved in comments at the top of the file.

    Note that for non-modular code, module_init() translates to
    device_initcall(). One could argue that we should use subsys_initcall()
    here, but for now we stick with runtime equivalence.

    We delete module.h but we keep the moduleparam.h include, since we are
    keeping the module_param() that the file has as-is for now.

  • 3784e0c6b   PCI: pciehp: Clean up debug logging ... Browse Code »

    The pciehp debug logging is overly verbose and often redundant. Almost all
    of the information printed by dbg_ctrl() is also printed by the normal PCI
    core enumeration code and by pcie_init().

    Remove the redundant debug info.

    When claiming a pciehp bridge, we print the slot characteristics, e.g.,

    Slot #6 AttnBtn- AttnInd- PwrInd- PwrCtrl- MRL- Interlock- NoCompl+ LLActRep+

    Add the Hot-Plug Capable and Hot-Plug Surprise bits to this information,
    and print it all in the same order as lspci does.

  • e705c2959   PCI: pciehp: Drop pointless ACPI-based "slot detection" check ... Browse Code »

    Jarod Wilson reports that ExpressCard hotplug doesn't work on HP ZBook G2.
    The problem turns out to be the ACPI-based "slot detection" code called
    from pciehp_probe() which uses questionable heuristics based on what ACPI
    objects are present for the PCIe port device to figure out whether to
    register a hotplug slot for that port.

    That code is used if there is at least one PCIe port having an ACPI device
    configuration object related to hotplug (such as _EJ0 or _RMV), and the
    Thunderbolt port on the ZBook has _RMV. Of course, Thunderbolt and PCIe
    native hotplug need not be mutually exclusive (as they aren't on the
    ZBook), so that rule is simply incorrect.

    Moreover, the ACPI-based "slot detection" check does not add any value if
    pciehp_probe() is called at all and the service type of the device object
    it has been called for is PCIE_PORT_SERVICE_HP, because PCIe hotplug
    services are only registered if the _OSC handshake in acpi_pci_root_add()
    allows the kernel to control the PCIe native hotplug feature. No more
    checks need to be carried out to decide whether or not to register a native
    PCIe hotlug slot in that case.

    For the above reasons, make pciehp_probe() check if it has been called for
    the right service type and drop the pointless ACPI-based "slot detection"
    check from it. Also remove the entire code whose only user is that check
    (the entire pciehp_acpi.c file goes away as a result) and drop function
    headers related to it from the internal pciehp header file.

  • c2be6f93b   PCI: pciehp: Use per-slot workqueues to avoid deadlock ... Browse Code »

    When we have a hotplug-capable PCIe port with a second hotplug-capable
    PCIe port below it, removing the device below the upstream port causes
    a deadlock.

    The deadlock happens because we use the pciehp_wq workqueue to run
    pciehp_power_thread(), which uses pciehp_disable_slot() to remove devices
    below the upstream port. When we remove the downstream PCIe port, we call
    pciehp_remove(), the pciehp driver's .remove() method. That calls
    flush_workqueue(pciehp_wq), which deadlocks because the
    pciehp_power_thread() work item is still running.

    This patch avoids the deadlock by creating a workqueue for every PCIe port
    and removing the single shared workqueue.

    Here's the call path that leads to the deadlock:

    pciehp_queue_pushbutton_work
    queue_work(pciehp_wq) # queue pciehp_power_thread
    ...

    pciehp_power_thread
    pciehp_disable_slot
    remove_board
    pciehp_unconfigure_device
    pci_stop_and_remove_bus_device
    ...
    pciehp_remove # pciehp driver .remove method
    pciehp_release_ctrl
    pcie_cleanup_slot
    flush_workqueue(pciehp_wq)

    This is fairly urgent because it can be caused by simply unplugging a
    Thunderbolt adapter, as reported by Daniel below.

  • 28eb5f274   PCI: PCIe: Ask BIOS for control of all native services at once ... Browse Code »

    After commit 852972acff8f10f3a15679be2059bb94916cba5d (ACPI: Disable
    ASPM if the platform won't provide _OSC control for PCIe) control of
    the PCIe Capability Structure is unconditionally requested by
    acpi_pci_root_add(), which in principle may cause problems to
    happen in two ways. First, the BIOS may refuse to give control of
    the PCIe Capability Structure if it is not asked for any of the
    _OSC features depending on it at the same time. Second, the BIOS may
    assume that control of the _OSC features depending on the PCIe
    Capability Structure will be requested in the future and may behave
    incorrectly if that doesn't happen. For this reason, control of
    the PCIe Capability Structure should always be requested along with
    control of any other _OSC features that may depend on it (ie. PCIe
    native PME, PCIe native hot-plug, PCIe AER).

    Rework the PCIe port driver so that (1) it checks which native PCIe
    port services can be enabled, according to the BIOS, and (2) it
    requests control of all these services simultaneously. In
    particular, this causes pcie_portdrv_probe() to fail if the BIOS
    refuses to grant control of the PCIe Capability Structure, which
    means that no native PCIe port services can be enabled for the PCIe
    Root Complex the given port belongs to. If that happens, ASPM is
    disabled to avoid problems with mishandling it by the part of the
    PCIe hierarchy for which control of the PCIe Capability Structure
    has not been received.

    Make it possible to override this behavior using 'pcie_ports=native'
    (use the PCIe native services regardless of the BIOS response to the
    control request), or 'pcie_ports=compat' (do not use the PCIe native
    services at all).

    Accordingly, rework the existing PCIe port service drivers so that
    they don't request control of the services directly.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
