* | | [PATCH] ipmi: add timer threadCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We must poll for responses to commands when interrupts aren't in use. The default poll interval is based on using a kernel timer, which varies with HZ. For character-based interfaces like KCS and SMIC though, that can be way too slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve the sensor list). This creates a low-priority kernel thread to poll more often. If the state machine is idle, so is the kernel thread. But if there's an active command, it polls quite rapidly. This decrease a firmware flash time from 15 minutes to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge x8x system. The timer-based polling remains, to ensure some amount of responsiveness even under high user process CPU load. Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to ensure safe stoppage.

* | | [PATCH] ipmi: kcs error0 delayCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | [PATCH] ipmi: bt restart reset fixesCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current BT retry/reset mechanism fails to succeed on a PowerEdge 1650, when the controller is wedged with B2H_ATN asserted at XACTION_START. If this occurs, no further commands will ever succeed unless the state of the controller is first cleared out. Furthermore, the soft reset would only occur if the first command after insmod was the one that timed out, not if a later command timed out. This patch changes the retry/reset mechanism to be as follows: Before retrying a command, clear the state of the BT controller such that the flags represent ready for a new transaction. This increases the chance of success of the restarted transaction. After 2 retries, issue a soft reset and retry one more time before giving up and reporting back a failure.

* | | [PATCH] ipmi: si start transaction hookCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some commands, on some system BMCs, don't respond at at all. This is seen on Dell PowerEdge x6xx and x7xx systems with IPMI 1.0 BT controllers when a "Get SDR" command is issued, with a length field of 0x3A, which happens to be the length of about SDR entries. If another length is passed, this command succeeds. This patch adds general infrastructure for receiving commands before they're passed down to the low-level drivers, such that they can be completed immediately, or modified, prior to being sent to ->start_transaction().

* | | [PATCH] ipmi: various si cleanupCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | [PATCH] ipmi: use refcount in message handlerCorey Minyard2005-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is rather large, but it really can't be done in smaller chunks easily and I believe it is an important change. This has been out and tested for a while in the latest IPMI driver release. There are no functional changes, just changes as necessary to convert the locking over (and a few minor style updates). The IPMI driver uses read/write locks to ensure that things exist while they are in use. This is bad from a number of points of view. This patch removes the rwlocks and uses refcounts and RCU lists to manage what the locks did.

Fixed Matthieu's concern about writing before discovery. (akpm: rmk said: This driver is buggy. You must not provide your own release function - it doesn't solve the problem which the warning (which you get when you don't provide one) is telling you about. You should convert your device driver over to the replacement dynamic platform support, once it is merged.
