* ipmi: remove trydefaults parameter and default initTony Camuso2016-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through the legacy port io space that was designated for ipmi. Architectures that do not map legacy port io can panic when trydefaults=1. Rather than implement build-time conditional exceptions for each architecture that does not map legacy port io, we have removed legacy port io from the driver. Parameter 'trydefaults' has been removed. Attempts to use it hereafter will evoke the "Unknown symbol in module, or unknown parameter" message. The patch was built against a number of architectures and tested for regressions and functionality on x86_64 and ARM64. Signed-off-by: Tony Camuso <tcamuso@redhat.com> Removed the config entry and the address source entry for default, since neither were used any more. Signed-off-by: Corey Minyard <cminyard@mvista.com>

* ipmi: Turn off all activity on an idle ipmi interfaceCorey Minyard2014-04-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The IPMI driver would wake up periodically looking for events and watchdog pretimeouts. If there is nothing waiting for these events, it's really kind of pointless to be checking for them. So modify the driver so the message handler can pass down if it needs the lower layer to be waiting for these. Modify the system interface lower layer to turn off all timer and thread activity if the upper layer doesn't need anything and it is not currently handling messages. And modify the message handler to not restart the timer if its timer is not needed. The timers and kthread will still be enabled if: - the SI interface is handling a message. - a user has enabled watching for events. - the IPMI watchdog timer is in use (since it uses pretimeouts). - the message handler is waiting on a remote response. - a user has registered to receive commands. This mostly affects interfaces without interrupts. Interfaces with interrupts already don't use CPU in the system interface when the interface is idle.

* device.h: audit and cleanup users in main include dirPaul Gortmaker2012-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* include: replace linux/module.h with "struct module" wherever possiblePaul Gortmaker2011-10-311-1/+2
| | | | | | | | | | | | | | | | | | | | | The <linux/module.h> pretty much brings in the kitchen sink along with it, so it should be avoided wherever reasonably possible in terms of being included from other commonly used <linux/something.h> files, as it results in a measureable increase on compile times. The worst culprit was probably device.h since it is used everywhere. This file also had an implicit dependency/usage of mutex.h which was masked by module.h, and is also fixed here at the same time. There are over a dozen other headers that simply declare the struct instead of pulling in the whole file, so follow their lead and simply make it a few more. Most of the implicit dependencies on module.h being present by these headers pulling it in have been now weeded out, so we can finally make this change with hopefully minimal breakage.

* IPMI: Add one interface to get more info of low-level IPMI deviceZhao Yakui2010-12-141-0/+38
| | | | | | | | | | | | | | | | | | | The IPMI smi_watcher will be used to catch the IPMI interface as they come or go. In order to communicate with the correct IPMI device, it should be confirmed whether it is what we wanted especially on the system with multiple IPMI devices. But the new_smi callback function of smi_watcher provides very limited info(only the interface number and dev pointer) and there is no detailed info about the low level interface. For example: which mechansim registers the IPMI interface(ACPI, PCI, DMI and so on). This is to add one interface that can get more info of low-level IPMI device. For example: the ACPI device handle will be returned for the pnp_acpi IPMI device.

* ipmi: run to completion fixesCorey Minyard2008-04-291-9/+2
| | | | | | | | | | | | | | | The "run_to_completion" mode was somewhat broken. Locks need to be avoided in run_to_completion mode, and it shouldn't be used by normal users, just internally for panic situations. This patch removes locks in run_to_completion mode and removes the user call for setting the mode. The only user was the poweroff code, but it was easily converted to use the polling interface.

* IPMI: add polled interfaceCorey Minyard2007-10-181-0/+10
| | | | | | | | | | | | Currently the IPMI watchdog timer sets the watchdog timeout on a panic, but it doesn't actually poll the interface to make sure the message goes out.

* [PATCH] IPMI: Add maintenance modeCorey Minyard2006-12-071-0/+45
| | | | | | | | | | | | | | | Some commands and operations on a BMC can cause the BMC to "go away" for a while. This can cause the automatic flag processing and other things of that nature to timeout and generate annoying logs, or possibly cause other bad things to happen when in firmware update mode. Add detection of those commands (cold reset, warm reset, and any firmware command) and turns off automatic processing for 30 seconds. It also add a manual override either way.

* [PATCH] ipmi: add full sysfs supportCorey Minyard2006-03-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | Add full driver model support for the IPMI driver. It links in the proper bus and device support. It adds an "ipmi" driver interface that has each BMC discovered by the driver (as a device). These BMCs appear in the devices/platform directory. If there are multiple interfaces to the same BMC, the driver should discover this and will only have one BMC entry. The BMC entry will have pointers to each interface device that connects to it. The device information (statistics and config information) has not yet been ported over to the driver model from proc, that will come later. This work was based on work by Yani Ioannou. I basically rewrote it using that code as a guide, but he still deserves credit :).

* [PATCH] ipmi: use refcount in message handlerCorey Minyard2005-11-071-4/+1
| | | | | | | | | | | | | | | | | 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.

* [PATCH] ipmi: fix panic ipmb responseCorey Minyard2005-09-071-1/+2
| | | | | | | | | | | | | The "null message handler" in the IPMI driver is used in startup and panic situations to handle messages. It was only designed to work with messages from the local management controller, but in some cases it was used to get messages from remote managmenet controllers, and the system would then panic. This patch makes the "null message handler" in the IPMI driver more general so it works with any kind of message.

| | | | | | | | | | | | | IPMI allows multiple IPMB channels on a single interface, and each channel might have a different IPMB address. However, the driver has only one IPMB address that it uses for everything. This patch adds new IOCTLS and a new internal interface for setting per-channel IPMB addresses and LUNs. New systems are coming out with support for multiple IPMB channels, and they are broken without this patch.

* [PATCH] ipmi: add power cycle capabilityCorey Minyard2005-06-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | This patch to adds "power cycle" functionality to the IPMI power off module ipmi_poweroff. It also contains changes to support procfs control of the feature. The power cycle action is considered an optional chassis control in the IPMI specification. However, it is definitely useful when the hardware supports it. A power cycle is usually required in order to reset a firmware in a bad state. This action is critical to allow remote management of servers. The implementation adds power cycle as optional to the ipmi_poweroff module. It can be modified dynamically through the proc entry mentioned above. During a power down and enabled, the power cycle command is sent to the BMC firmware. If it fails either due to non-support or some error, it will retry to send the command as power off. Signed-off-by: Christopher A.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+602
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!
