2005-11-07[PATCH] ipmi: kcs error0 delayCorey Minyard
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.

2005-11-07[PATCH] ipmi: various si cleanupCorey Minyard
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.

2005-09-07[PATCH] ipmi: clean up versioning of the IPMI driverCorey Minyard
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.

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!
