ipmi: Don't allow device module unload when in use

2019-10-22T19:42:34+00:00

If something has the IPMI driver open, don't allow the device
module to be unloaded.  Before it would unload and the user would
get errors on use.

This change is made on user request, and it makes it consistent
with the I2C driver, which has the same behavior.

It does change things a little bit with respect to kernel users.
If the ACPI or IPMI watchdog (or any other kernel user) has
created a user, then the device module cannot be unloaded.  Before
it could be unloaded,

This does not affect hot-plug.  If the device goes away (it's on
something removable that is removed or is hot-removed via sysfs)
then it still behaves as it did before.

ipmi: Make the smi watcher be disabled immediately when not needed

2019-02-10T01:48:42+00:00

The code to tell the lower layer to enable or disable watching for
certain things was lazy in disabling, it waited until a timer tick
to see if a disable was necessary.  Not a really big deal, but it
could be improved.

Modify the code to enable and disable watching immediately and don't
do it from the background timer any more.

ipmi: Fix how the lower layers are told to watch for messages

2019-02-10T01:48:42+00:00

The IPMI driver has a mechanism to tell the lower layers it needs
to watch for messages, commands, and watchdogs (so it doesn't
needlessly poll).  However, it needed some extensions, it needed
a way to tell what is being waited for so it could set the timeout
appropriately.

The update to the lower layer was also being done once a second
at best because it was done in the main timeout handler.  However,
if a command is sent and a response message is coming back,
it needed to be started immediately.  So modify the code to
update immediately if it needs to be enabled.  Disable is still
lazy.

ipmi: Add shutdown functions for users and interfaces

2018-04-18T15:22:54+00:00

Since things that IPMI uses can be hot-swapped, the users and
interfaces really need to be able to handle this.

Add the functions so the users and interfaces can implement
them, the actual function will be added after everything is
ready.
