eb6d78ec21 ipmi: Reset the KCS timeout when starting error recovery
The OBF timer in KCS was not reset in one situation when error recovery
was started, resulting in an immediate timeout.

828dc9da50 ipmi: increase KCS timeouts
We currently time out and retry KCS transactions after 1 second of waiting
for IBF or OBF.  This appears to be too short for some hardware.  The IPMI
spec says "All system software wait loops should include error timeouts.
For simplicity, such timeouts are not shown explicitly in the flow
diagrams.  A five-second timeout or greater is recommended".  Change the
timeout to five seconds to satisfy the slow hardware.

message size the rest of the driver supports.  Some systems really support

4d7cbac7c8 [PATCH] IPMI: Fix BT long busy
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.

c3e7e7916e [PATCH] ipmi: kcs error0 delay
BMCs can get into ERROR0 state while flashing new firmware, particularly while
the BMC is erasing the next flash block, which may take a just under 2 seconds
on a Dell PowerEdge 2800 (1.75 seconds typical), during which time the
single-threaded firmware may not be able to process new commands.  In
particular, clearing OBF may not take effect immediately.

We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to
actually be clear before proceeding.

This introduces a new return value from the LLDD's event loop,
SI_SM_CALL_WITH_TICK_DELAY.  This means the calling thread/timer should
schedule_timeout() at least 1 tick, rather than busy-wait.  This is a longer
delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

c4edff1c19 [PATCH] ipmi: various si cleanup
A number of small changes for the various system interface drivers,
consolidated from a number of patches from Matt Domsch.

Clear B2H_ATN and drain the BMC message buffer on command timeout.  This
prevents further commands from failing after a timeout.

Add bt_debug and smic_debug module parameters, expose them in sysfs.  This
lets you enable and disable debugging messages at runtime.

Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed
to ->event() after jiffies wrap-around.  The BT driver had caught this, but
didn't know how to fix it.  Now all calls to ->event() use a sane value for
time.

Increase timeout for commands handed to the BT driver from 2 seconds to 5
seconds.  This is necessary particularly when the previous command was a
"Clear SEL", as that command completes, yet the BMC isn't really ready to
handle another command yet.

Silence BT debugging messages which were being printed on the console.

Increase SMIC timeout form 1/10s to 2s.  This is needed on Dell PowerEdge 2650
and PowerEdge 750 with ERA/O cards to allow commands to complete without
timing out.

Adds kcs_debug module param, to match behavior of BT and SMIC.  This also
prevents messages from being sent to the console unless explicitly requested.

1fdd75bd6c [PATCH] ipmi: clean up versioning of the IPMI driver
This adds MODULE_VERSION, MODULE_DESCRIPTION, and MODULE_AUTHOR tags to the
IPMI driver modules.  Also changes the MODULE_VERSION to remove the
prepended 'v' on each value, consistent with the module versioning policy.

This patch also removes all the version information from everything except
the ipmi_msghandler module.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
