| * dm kcopyd: fix callback raceMikulas Patocka2009-04-091-6/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the thread calling dm_kcopyd_copy is delayed due to scheduling inside split_job/segment_complete and the subjobs complete before the loop in split_job completes, the kcopyd callback could be invoked from the thread that called dm_kcopyd_copy instead of the kcopyd workqueue. dm_kcopyd_copy -> split_job -> segment_complete -> job->fn() Snapshots depend on the fact that callbacks are called from the singlethreaded kcopyd workqueue and expect that there is no racing between individual callbacks. The racing between callbacks can lead to corruption of exception store and it can also mean that exception store callbacks are called twice for the same exception - a likely reason for crashes reported inside pending_complete() / remove_exception(). This patch fixes two problems: 1. job->fn being called from the thread that submitted the job (see above). - Fix: hand over the completion callback to the kcopyd thread. 2. job->fn(read_err, write_err, job->context); in segment_complete reports the error of the last subjob, not the union of all errors. - Fix: pass job->write_err to the callback to report all error bits (it is done already in run_complete_job) Cc: stable@kernel.org Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

| | | | | | | | | | | | | | | | | | | | Use a variable in segment_complete() to point to the dm_kcopyd_client struct and only release job->pages in run_complete_job() if any are defined.

| * dm: implement basic barrier supportMikulas Patocka2009-04-091-20/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Barriers are submitted to a worker thread that issues them in-order. The thread is modified so that when it sees a barrier request it waits for all pending IO before the request then submits the barrier and waits for it. (We must wait, otherwise it could be intermixed with following requests.) Errors from the barrier request are recorded in a per-device barrier_error variable. There may be only one barrier request in progress at once. For now, the barrier request is converted to a non-barrier request when sending it to the underlying device. This patch guarantees correct barrier behavior if the underlying device doesn't perform write-back caching. The same requirement existed before barriers were supported in dm. Bottom layer barrier support (sending barriers by target drivers) and handling devices with write-back caches will be done in further patches.

| * dm: remove dm_request loopMikulas Patocka2009-04-091-15/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove queue_io return value and a loop in dm_request. IO may be submitted to a worker thread with queue_io(). queue_io() sets DMF_QUEUE_IO_TO_THREAD so that all further IO is queued for the thread. When the thread finishes its work, it clears DMF_QUEUE_IO_TO_THREAD and from this point on, requests are submitted from dm_request again. This will be used for processing barriers. Remove the loop in dm_request. queue_io() can submit I/Os to the worker thread even if DMF_QUEUE_IO_TO_THREAD was not set.

| * | pda_power: Add optional OTG transceiver and voltage regulator supportPhilipp Zabel2009-02-021-12/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows machines to use an OTG transceiver driver instead of supplying a custom is_usb_online callback to check USB power. Also, in the case that the OTG transceiver handles charger control when connected to USB, a regulator named "ac_draw" can be supplied instead of the custom set_charge callback to control the charger when connected to AC. The check for (transceiver->state == OTG_STATE_B_PERIPHERAL) in otg_is_usb_online is probably too simple, I'm just using this with a peripheral only device and gpio_vbus + bq24022. I'm not sure which other OTG states can supply power. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The battery charger state machine switches into charging mode when the battery voltage falls below 96% of a battery float voltage. But the voltage drop in Li-ion batteries is marginal(1~2 %) till about 80% of its capacity - which means, after a BATFULL, charging won't be restarted until 80%. This work_struct function restarts charging at regular intervals to make sure the battery doesn't discharge too much.

| * | | igb: remove sysfs entry that was used to set the number of vfsAlexander Duyck2009-04-081-105/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the sysfs entry num_vfs which was added to support enabling pci virtual functions for 82576. To prevent VFs from loading automatically a module parameter "max_vfs" was added so that the number of VFs per PF can be limited. This is especially useful when 4 or more 82576 ports are on the system because otherwise to load all VFs would result in 8 interface per physical port.

A virtual function is a lightweight pci-e function that supports a single queue and shares resources with the 82576 physical function contained within the igb driver. To spawn virtual functions from the igb driver all that is needed is to enable CONFIG_PCI_IOV and have an 82576 Ethernet adapter on a system that supports SR-IOV in the BIOS. The virtual functions will appear after the interface is loaded.

However ACPI handles temperature values with a single decimal place. As a consequence, some implementations use an offset of 273.1 and others use an offset of 273.2. Try to find out which one is being used, to present the most accurate and visually appealing number. Tested on a Sony Vaio PGC-GR214EP (which uses 273.1) and a Lenovo Thinkpad T60p (which uses 273.2).

This theory is supported by the fact that the bad RIP value is a vmalloc address. The immediate fix is to make this a non-init call. (A better long-term fix is of course to wait with init-section unloading until a module's async initcalls have been run, which would allow us to discard this function which is still only run once, after all. Perhaps a new async_initcall() function for the async/module API, if this is needed for other modules in the future?)

This bit means the APIC timer continues to run even when CPU is in deep C-states. The advantage is that we can use LAPIC timer on these CPUs always, and there is no need for "slow to read and program" external timers (HPET/PIT) and the timer broadcast logic and related code in C-state entry and exit.
