In some cases kipmid can use a lot of CPU. This adds a way to tune the CPU used by kipmid to help in those cases. By setting kipmid_max_busy_us to a value between 100 and 500, it is possible to bring down kipmid CPU load to practically 0 without loosing too much ipmi throughput performance. Not setting the value, or setting the value to zero, operation is unaffected.

Convert over to the new NMI handling for getting IPMI watchdog timeouts via an NMI. This add config options to know if there is the ability to receive NMIs and if it has an NMI post processing call. Then it modifies the IPMI watchdog to take advantage of this so that it can know if an NMI comes in. It also adds testing that the IPMI NMI watchdog works.

Clean up IPMI documentation to remove references to high-res timers and add info about the polling thread. Also fix an doc error for a parameter.

Add the ability to hot add and remove interfaces in the ipmi_si driver. Any users who have the device open will get errors if they try to send a message. Signed-off-by: Corey Minyard <minyard@acm.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
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.

After the previous patch to disable the kernel IPMI daemon if interrupts were available, the issue of broken hardware was raised, and a reasonable request to add an override was mode. So here it is. Allow the user to force the kernel ipmi daemon on or off. This way, hardware with broken interrupts or users that are not concerned with performance can turn it on or off to their liking.

This patch adds the ability to register for a command per-channel in the IPMI driver. If your BMC supports multiple channels, incoming messages can be useful to have the ability to register to receive commands on a specific channel instead the current behaviour of all channels.
