Add an OpenIPMI mostly compatible driver. This driver was developed to work with ipmitools. It works with other tools that have an OpenIPMI driver interface. The port will need to get updated to used this. I have not implemented the IPMB mode yet so ioctl's for that don't really do much otherwise it should work like the OpenIPMI version. The ipmi.h definitions was derived from the ipmitool header file. The bus attachments are done for smbios and pci/smbios. Differences in bus probe order for modules/static are delt with. ACPI attachment should be done. This drivers registers with the watchdod(4) interface Work to do: - BT interface - IPMB mode This has been tested on Dell PE2850, PE2650 & PE850 with i386 & amd64 kernel. I will link this into the build on next week. Tom Rhodes, helped me with the man page. Sponsored by: IronPort Systems Inc. Inspired from: ipmitool & Linux

/*-
sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Update the ipmi(4) driver: - Split out the communication protocols into their own files and use a couple of function pointers in the softc that the commuication protocols setup in their own attach routine. - Add support for the SSIF interface (talking to IPMI over SMBus). - Add an ACPI attachment. - Add a PCI attachment that attaches to devices with the IPMI interface subclass. - Split the ISA attachment out into its own file: ipmi_isa.c. - Change the code to probe the SMBIOS table for an IPMI entry to just use pmap_mapbios() to map the table in rather than trying to setup a fake resource on an isa device and then activating the resource to map in the table. - Make bus attachments leaner by adding attach functions for each communication interface (ipmi_kcs_attach(), ipmi_smic_attach(), etc.) that setup per-interface data. - Formalize the model used by the driver to handle requests by adding an explicit struct ipmi_request object that holds the state of a given request and reply for the entire lifetime of the request. By bundling the request into an object, it is easier to add retry logic to the various communication backends (as well as eventually support BT mode which uses a slightly different message format than KCS, SMIC, and SSIF). - Add a per-softc lock and remove D_NEEDGIANT as the driver is now MPSAFE. - Add 32-bit compatibility ioctl shims so you can use a 32-bit ipmitool on FreeBSD/amd64. - Add ipmi(4) to i386 and amd64 NOTES.

Use this for kcs_polled_request() and smic_polled_request(). - Add a new backend callback "ipmi_driver_request" to handle a driver request. The new callback performs the request sychronously for KCS and SMIC. SSIF still defers the work to the worker thread since the worker thread sleeps during request processing anyway. - Allocate driver requests on the stack rather than using malloc().

Implement IPMI support for RB_POWRECYCLE Some BMCs support power cycling the chassis via the chassis control command 2 subcommand 2 (ipmitool called it 'chassis power cycle'). If the BMC supports the chassis device, register a shutdown_final handler that sends the power cycle command if request and waits up to 10s for it to take effect. To minimize stack strain, we preallocate a ipmi request in the softc. At the moment, we're verbose about what we're doing. Sponsored by: Netflix

Watchdog drivers need to support rearming the watchdog in contexts which are not permitted to sleep. Only use the IPMI watchdog with backends which poll driver-initiated requests to meet this requirement. In practice this means that watchdogs will no longer be used on systems that use the SSIF backend. Differential Revision: https://reviews.freebsd.org/D2062 MFC after: 2 weeks

Implement IPMI support for RB_POWRECYCLE Some BMCs support power cycling the chassis via the chassis control command 2 subcommand 2 (ipmitool called it 'chassis power cycle'). If the BMC supports the chassis device, register a shutdown_final handler that sends the power cycle command if request and waits up to 10s for it to take effect. To minimize stack strain, we preallocate a ipmi request in the softc. At the moment, we're verbose about what we're doing. Sponsored by: Netflix

Don't try to stop the IPMI watchdog timer if it is not running. Starting or stopping the IPMI watchdog is rather expensive with the current implementation as all IPMI requests are bounced via thread. This is not viable during shutdown or dumps, and this avoids headache in the common case that the watchdog is not enabled. The IPMI watchdog should probably be reworked to not use a separate thread to fix this in the case when the watchdog timer is enabled. MFC after: 2 weeks

Update the ipmi(4) driver: - Split out the communication protocols into their own files and use a couple of function pointers in the softc that the commuication protocols setup in their own attach routine. - Add support for the SSIF interface (talking to IPMI over SMBus). - Add an ACPI attachment. - Add a PCI attachment that attaches to devices with the IPMI interface subclass. - Split the ISA attachment out into its own file: ipmi_isa.c. - Change the code to probe the SMBIOS table for an IPMI entry to just use pmap_mapbios() to map the table in rather than trying to setup a fake resource on an isa device and then activating the resource to map in the table. - Make bus attachments leaner by adding attach functions for each communication interface (ipmi_kcs_attach(), ipmi_smic_attach(), etc.) that setup per-interface data. - Formalize the model used by the driver to handle requests by adding an explicit struct ipmi_request object that holds the state of a given request and reply for the entire lifetime of the request. By bundling the request into an object, it is easier to add retry logic to the various communication backends (as well as eventually support BT mode which uses a slightly different message format than KCS, SMIC, and SSIF). - Add a per-softc lock and remove D_NEEDGIANT as the driver is now MPSAFE. - Add 32-bit compatibility ioctl shims so you can use a 32-bit ipmitool on FreeBSD/amd64. - Add ipmi(4) to i386 and amd64 NOTES.

Add an OpenIPMI mostly compatible driver. This driver was developed to work with ipmitools. It works with other tools that have an OpenIPMI driver interface. The port will need to get updated to used this. I have not implemented the IPMB mode yet so ioctl's for that don't really do much otherwise it should work like the OpenIPMI version. The ipmi.h definitions was derived from the ipmitool header file. The bus attachments are done for smbios and pci/smbios. Differences in bus probe order for modules/static are delt with. ACPI attachment should be done. This drivers registers with the watchdod(4) interface Work to do: - BT interface - IPMB mode This has been tested on Dell PE2850, PE2650 & PE850 with i386 & amd64 kernel. I will link this into the build on next week. Tom Rhodes, helped me with the man page. Sponsored by: IronPort Systems Inc. Inspired from: ipmitool & Linux

Use direct hardware access for internal requests for KCS and SMIC. In particular, updates to the watchdog should no longer sleep. - Add a new IPMI_IO_LOCK for low-level I/O access. Use this for kcs_polled_request() and smic_polled_request(). - Add a new backend callback "ipmi_driver_request" to handle a driver request. The new callback performs the request sychronously for KCS and SMIC. SSIF still defers the work to the worker thread since the worker thread sleeps during request processing anyway. - Allocate driver requests on the stack rather than using malloc().
