video1394 does not need to take the BKL. The data structures shared between file_operations and interrupts are already protected through context-specific spinlocks. The only other danger is video1394_release() being called during another operation, however this cannot happen because release is only ever invoked when the last thread has closed the fd.

Bernhard Kaindl authored
I did a quick shot on what I described and the appended patch does the first thing needed for working suspend/resume in ohci1394 which is HW de- and re-initialisation. It works with suspend2disk on my Ricoh R5C552 IEEE 1394 Controller with the 2.6.17 kernel to the extent that if I call dvgrab --interactive after suspend2disk without unloading ohci1394, it does not lock up dvgrab with 100% CPU but properly connects to the camera, given that I first unplug and plug the camera after coming back from suspend. I guess that could be fixed by forcing a bus reset in the resume function. I cannot test suspend to RAM here at the moment and should follow the guidelines in Documentation/power/pci.txt also, so this is rather a quick report than a finished patch and there are some rough edges: However, with this patch, I have to unload at least some in-kernel users of ohci1394 like dv1394 or video1394 before suspending. Not doing that caused an Oops and a bad tasklet error, probably from not handling ISO tasklets during suspend/resume properly. Maybe these can be temporarily cleared or unregistered and re-registered for suspend/resume with help from the other layers or from the highlevel 1394 core, but I do not really know what these do. But this patch provides a useful base to start from and is already of much help for people which do not need dv1394 and video1394 or can unload them at least during suspend. I cannot test function with sbp2 at the moment, but raw1394 seems to work fine. Signed-off-by:

Put the target's fetch agent into reset state before the underlying ORB DMA is unmapped and the ->done handler is called. It is highly unlikely but the target could access that ORB right before sbp2 sends the reset request. Signed-off-by: -

struct hpsb_highlevel's struct module *owner is neither used by the IEEE 1394 core nor set by any of the in-tree drivers or the two out-of-tree highlevel drivers I know about (dfg1394, mem1394) --- nor is this member documented. An unscheduled removal seems acceptable. Signed-off-by: -

This allows workqueue users to run just their own pending work, rather than wait for the whole workqueue to finish running. This solves the deadlock with networking libphy that was due to other workqueue entries possibly needing a lock that was held by the routine that wanted to flush its own work. It's not wonderful: if you absolutely need to synchronize with the work function having been executed, any user strictly speaking should have its own completion tracking logic, since when we run things explicitly by hand, the generic workqueue layer can no longer help us synchronize. Also, this is strictly only usable for work that has been scheduled without any delayed timers. You can not mix the new interface with schedule_delayed_work(). But it's better than what we had currently. Acked-by:

The IPMI BT subdriver has been patched to survive "long busy" timeouts seen during firmware upgrades and resets. The patch never returns the HOSED state, synthesizes response messages with meaningful completion codes, and recovers gracefully when the hardware finishes the long busy. The subdriver now issues a "Get BT Capabilities" command and properly uses those results. More informative completion codes are returned on error from transaction starts; this logic was propogated to the KCS and SMIC subdrivers. Finally, indent and other style quirks were normalized.

Make sure to delay a little in the IPMI poll routine so we can pass in a timeout time and thus time things out. Signed-off-by:

Corey Minyard authored
When the IPMI message handler requested that the interface look for events, the ipmi_si driver would request flags, see if the event buffer full flag was set, then request events. It's better to just send the request for events, as it cuts one message out of the transaction if there happens to be events, and it will fetch events even if the event buffer was not full.

Some commands and operations on a BMC can cause the BMC to "go away" for a while. This can cause the automatic flag processing and other things of that nature to timeout and generate annoying logs, or possibly cause other bad things to happen when in firmware update mode. Add detection of those commands (cold reset, warm reset, and any firmware command) and turns off automatic processing for 30 seconds. It also add a manual override either way. Signed-off-by:

This modifies the IPMI driver so that a lower-level interface can be dynamically removed while in use so it can support hot-removal of hardware. It also adds the ability to specify and dynamically change the IPMI interface the watchdog timer and the poweroff code use. Signed-off-by:
