ipmi: Add Loongson-2K BMC support

2025-09-16T15:15:54+00:00

This patch adds Loongson-2K BMC IPMI support. According to the existing design, we use software simulation to implement the KCS interface registers: Stauts/Command/Data_Out/Data_In. Also since both host side and BMC side read and write kcs status, fifo flag is used to ensure data consistency. The single KCS message block is as follows: +-------------------------------------------------------------------------+ |FIFO flags| KCS register data | CMD data | KCS version | WR REQ | WR ACK | +-------------------------------------------------------------------------+ Co-developed-by: Chong Qiao Signed-off-by: Chong Qiao Reviewed-by: Huacai Chen Acked-by: Corey Minyard Signed-off-by: Binbin Zhou Message-ID: <8f9ffb6f0405345af8f04193ce1510aacd075e72.1756987761.git.zhoubinbin@loongson.cn> Signed-off-by: Corey Minyard

ipmi:si: Move SI type information into an info structure

2025-05-07T22:25:47+00:00

Andy reported: Debian clang version 19.1.7 is not happy when compiled with `make W=1` (note, CONFIG_WERROR=y is the default): ipmi_si_platform.c:268:15: error: cast to smaller integer type 'enum si_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] 268 | io.si_type = (enum si_type)device_get_match_data(&pdev->dev); The IPMI SI type is an enum that was cast into a pointer that was then cast into an enum again. That's not the greatest style, so instead create an info structure to hold the data and use that.

parisc: Make struct parisc_driver::remove() return void

2021-08-30T08:18:25+00:00

The caller of this function (parisc_driver_remove() in arch/parisc/kernel/drivers.c) ignores the return value, so better don't return any value at all to not wake wrong expectations in driver authors. The only function that could return a non-zero value before was ipmi_parisc_remove() which returns the return value of ipmi_si_remove_by_dev(). Make this function return void, too, as for all other callers the value is ignored, too. Also fold in a small checkpatch fix for: WARNING: Unnecessary space before function pointer arguments + void (*remove) (struct parisc_device *dev); Acked-by: Dmitry Torokhov (for drivers/input) Signed-off-by: Uwe Kleine-König Acked-by: Sudip Mukherjee Acked-by: Jiri Slaby Signed-off-by: Helge Deller

ipmi_si: Get rid of ->addr_source_cleanup()

2021-04-02T17:53:34+00:00

The ->addr_source_cleanup() callback is solely used by PCI driver and only for one purpose, i.e. to disable device. Get rid of ->addr_source_cleanup() by switching to PCI managed API.

ipmi_si: Reuse si_to_str[] array in ipmi_hardcode_init_one()

2021-04-02T17:53:32+00:00

Instead of making the comparison one by one, reuse si_to_str[] array in ipmi_hardcode_init_one() in conjunction with match_string() API. Signed-off-by: Andy Shevchenko Message-Id: <20210402174334.13466-7-andriy.shevchenko@linux.intel.com> Signed-off-by: Corey Minyard

ipmi_si: Rework some include files

2019-08-02T12:25:03+00:00

ipmi_si_sm.h was getting included in lots of places it didn't belong. Rework things a bit to remove all the dependencies, mostly just moving things between include files that were in the wrong place and removing bogus includes. Signed-off-by: Corey Minyard

ipmi_si: Remove hotmod devices on removal and exit

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

When a hotmod-added device is removed or when the module is removed, remove the platform devices that was created for it. Signed-off-by: Corey Minyard

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_si: Rename addr_type to addr_space to match what it does

Make the naming consistent, and make the values an enum. Signed-off-by: Corey Minyard
