ipmi:bt: Set the timeout before doing a capabilities check

2018-07-03T09:26:49+00:00

commit fe50a7d0393a552e4539da2d31261a59d6415950 upstream. There was one place where the timeout value for an operation was not being set, if a capabilities request was done from idle. Move the timeout value setting to before where that change might be requested. IMHO the cause here is the invisible returns in the macros. Maybe that's a job for later, though.

ipmi: NPCM7xx KCS BMC: enable interrupt to the host

2018-06-19T03:05:38+00:00

Original kcs_bmc_npcm7xx.c was missing enabling to send interrupt to the host on writes to output buffer. This patch fixes it by setting the bits that enables the generation of IRQn events by hardware control based on the status of the OBF flag.

ipmi: add an NPCM7xx KCS BMC driver

2018-06-19T03:05:38+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/parisc: Add IPMI chassis poweroff for certain HP PA-RISC and IA-64 servers

2018-03-27T16:04:17+00:00

This patch allows HP PA-RISC servers like rp3410/rp3440 and the HP C8000 workstation with an IPMI controller that predate IPMI 1.5 to use the standard poweroff or powercycle commands. These systems firmware don't set the chassis capability bit in the Get Device ID, but they do implement the standard poweroff and powercycle commands.

ipmi: Remove ACPI SPMI probing from the system interface driver

2018-03-12T12:03:06+00:00

The IPMI spec states: The purpose of the SPMI Table is to provide a mechanism that can be used by the OSPM (an ACPI term for “OS Operating System-directed configuration and Power Management” essentially meaning an ACPI-aware OS or OS loader) very early in the boot process, e.g., before the ability to execute ACPI control methods in the OS is available. When we are probing IPMI in Linux, ACPI control methods are available, so we shouldn't be probing using SPMI. It could cause some confusion during the probing process. Signed-off-by: Corey Minyard
