ipmi:ipmb: Add initial support for IPMI over IPMB

2021-10-05T11:54:17+00:00

This provides access to the management controllers on an IPMB bus to a device sitting on the IPMB bus. It also provides slave capability to respond to received messages on the bus. Signed-off-by: Corey Minyard Tested-by: Andrew Manley Reviewed-by: Andrew Manley

ipmi: kcs_bmc: Add serio adaptor

2021-06-22T00:50:28+00:00

kcs_bmc_serio acts as a bridge between the KCS drivers in the IPMI subsystem and the existing userspace interfaces available through the serio subsystem. This is useful when userspace would like to make use of the BMC KCS devices for purposes that aren't IPMI.

ipmi: kcs_bmc: Decouple the IPMI chardev from the core

2021-06-22T00:50:22+00:00

Now that we have untangled the data-structures, split the userspace interface out into its own module. Userspace interfaces and drivers are registered to the KCS BMC core to support arbitrary binding of either.

ipmi: kcs_bmc: Split out kcs_bmc_cdev_ipmi

2021-06-22T00:50:13+00:00

Take steps towards defining a coherent API to separate the KCS device drivers from the userspace interface. Decreasing the coupling will improve the separation of concerns and enable the introduction of alternative userspace interfaces. For now, simply split the chardev logic out to a separate file. The code continues to build into the same module. Signed-off-by: Andrew Jeffery Reviewed-by: Zev Weiss Message-Id: <20210608104757.582199-5-andrew@aj.id.au> Signed-off-by: Corey Minyard

Add support for IPMB driver

2019-06-10T19:47:10+00:00

Support receiving IPMB requests on a Satellite MC from the BMC. Once a response is ready, this driver will send back a response to the BMC via the IPMB channel.

ipmi: Consolidate the adding of platform devices

2019-02-22T13:12:41+00:00

It was being done in two different places now that hard-coded devices use platform devices, and it's about to be three with hotmod switching to platform devices. So put the code in one place. This required some rework on some interfaces to make the type space clean. Signed-off-by: Corey Minyard

ipmi: add an NPCM7xx KCS BMC driver

2018-04-18T15:23:12+00:00

This driver exposes the Keyboard Controller Style (KCS) interface on Novoton NPCM7xx SoCs as a character device. Such SOCs are commonly used as a BaseBoard Management Controller (BMC) on a server board, and KCS interface is commonly used to perform the in-band IPMI communication between the server and its BMC.

ipmi: add an Aspeed KCS IPMI BMC driver

2018-02-26T15:21:28+00:00

The KCS (Keyboard Controller Style) interface is used to perform in-band IPMI communication between a server host and its BMC (BaseBoard Management Controllers). This driver exposes the KCS interface on ASpeed SOCs (AST2400 and AST2500) as a character device. Such SOCs are commonly used as BMCs and this driver implements the BMC side of the KCS interface.

ipmi: add a KCS IPMI BMC driver

2018-02-26T15:21:28+00:00

Provides a device driver for the KCS (Keyboard Controller Style) IPMI interface which meets the requirement of the BMC (Baseboard Management Controllers) side for handling the IPMI request from host system software.

Merge tag 'ipmi-for-4.15' of git://github.com/cminyard/linux-ipmi

2017-11-15T23:12:28+00:00

Pull IPMI updates from Corey Minyard: "This is a fairly large rework of the IPMI code, along with a bunch of smaller fixes. The major changes have been in the next tree for a couple of months, so they should be good to do in. - Some users had IPMI systems where the GUID of the IPMI controller could change. So rescanning of the GUID was added. The naming of some sysfs things was dependent on the GUID, however, so this resulted in the sysfs interface code in IPMI changing to remove that dependency and name the IPMI BMCs like other sysfs devices. - The ipmi_si_intf.c code was fairly bloated with all the different discovery methods (PCI, ACPI, SMBIOS, OF, platform, module parameters, hot add). The structure of how the interfaces were added was redone to make them more modular, then the individual methods were pulled out into their own files" * tag 'ipmi-for-4.15' of git://github.com/cminyard/linux-ipmi: (48 commits) ipmi_si: Delete an error message for a failed memory allocation in try_smi_init() ipmi_si: fix memory leak on new_smi ipmi: remove redundant initialization of bmc ipmi: pr_err() strings should end with newlines ipmi: Clean up some print operations ipmi: Make the DMI probe into a generic platform probe ipmi: Make the IPMI proc interface configurable ipmi_ssif: Add device attrs for the things in proc ipmi_si: Add device attrs for the things in proc ipmi_si: remove ipmi_smi_alloc() function ipmi_si: Move port and mem I/O handling to their own files ipmi_si: Get rid of unused spacing and port fields ipmi_si: Move PARISC handling to another file ipmi_si: Move PCI setup to another file ipmi_si: Move platform device handling to another file ipmi_si: Move hardcode handling to a separate file. ipmi_si: Move the hotmod handling to another file. ipmi_si: Change ipmi_si_add_smi() to take just I/O info ipmi_si: Move io setup into io structure ipmi_si: Move irq setup handling into the io struct ...
