meta-phosphor: mctp: enable MCTP over USB

2025-05-14T12:43:24+00:00

Now that the MCTP over USB driver is in openbmc/linux, enable the kernel config for the same. I've tested MCTP over USB on the Nvidia GB200NVL platform. Change-Id: I4bdb8fa9730c24f258f8682d366282e76ea52ccc Signed-off-by: Deepak Kodihalli

meta-phosphor: Add option to enable cgroup support

2025-05-02T16:43:20+00:00

We've noticed some poor behavior of systemd processes on the Meta BMCs. We enabled these kernel configurations to ensure we get memory limits adhered to and can easily debug things. Test Plan: Verified that this configuration was picked up in YV4 and that when this is not specified, none of these new kernel config options are picked up.

meta-phosphor: Add MCTP i3C transport

2025-04-21T14:55:17+00:00

This transport is widely used. Addd it to the MCTP default options. Change-Id: I799a5daa99825b8adbbd4052edc6186a00200a50 Signed-off-by: Ed Tanous

meta-phosphor: add distro feature production-level tweaks

2025-04-08T12:51:22+00:00

There are some settings that are desired to be set for production-level systems, but may be less desired in development. Such as settings that turn hard-errors into soft-errors. Add a distro feature to allow these settings to be enabled. Add as a production-level tweak, a config for the kernel default setting of `hung_task_panic`. This prevents unnecessary panics due to a busy system, usually due to poor driver implementations. Enable the production-level tweaks on meta-facebook. Tested: ``` root@yosemite4:~# cat /proc/sys/kernel/hung_task_panic 0 ``` Change-Id: I0542547c77ddacae44d98e9ab6edc3743ff0016c Signed-off-by: Cosmo Chou Signed-off-by: Patrick Williams

meta-phosphor: add nfs distro feature

2024-04-25T22:41:16+00:00

Add include files for NFS distro features, which enables NFS kernel configuration and utility to mount NFS from BMC. Tested: 1. Check if CONFIG_NFS_* are enabled $ zcat /proc/config.gz | grep NFS 2. Mount remote NFS folder $ mount -t nfs 10.10.130.2:/tftpboot/ISO_file /tmp/mount_nfs Change-Id: I015f4f6ed9c5b60573340233aee1f781aa0c573a Signed-off-by: Thang Q. Nguyen

treewide: linux: remove cfg files from SRC_URI

2024-04-15T19:15:11+00:00

When using a `feature.scc` file it is not necessary to also include the corresponding `feature.cfg` file in the `SRC_URI` field. Remove them to clean up. [1]: https://docs.yoctoproject.org/kernel-dev/advanced.html#recipe-space-metadata Tested: Built on Yosemite4 and observed MCTP configure options are still enabled. ``` root@yosemite4:~# zcat /proc/config.gz | grep MCTP CONFIG_MCTP=y CONFIG_MCTP_FLOWS=y # MCTP Device Drivers CONFIG_MCTP_SERIAL=y CONFIG_MCTP_TRANSPORT_I2C=y # end of MCTP Device Drivers ``` Signed-off-by: Patrick Williams Change-Id: I76656cf9fbbe5cd2ac44f90c46b391111ca72410

meta-phosphor: linux: simplify mctp config selection

Leverage the mctp DISTRO_FEATURE to simplify the selection of the mctp kernel config. Signed-off-by: Patrick Williams Change-Id: If01e472b9128d1e90fd29e1e31cef284057890fe

meta-ibm: p10bmc: add a MCTP DISTRO_FEATURES switch

2023-06-13T23:50:06+00:00

The switch enables AF_MCTP and adds the `mctp` tool and `mctpd` so we can setup and manage an in-kernel MCTP network. Enable it for p10bmc and also add CONFIG_TUN so we can use a tun device to transport packets between the kernel and the astlpc interface implemented in libmctp.

meta-phosphor: linux: Enable CONFIG_SCHEDSTATS for systemd-bootchart

2023-06-08T00:46:24+00:00

systemd-bootchart requires CONFIG_SCHEDSTATS=y to operate. Enabling it adds 4344 bytes to the p10bmc zImage (used as a test platform in this instance), which is likely tolerable for a default configuration: ``` $ ls -l zImage.* -rw-r--r--. 1 andrew andrew 4179240 Jun 2 14:28 zImage.no-schedstats -rw-r--r--. 1 andrew andrew 4183584 Jun 2 14:19 zImage.schedstats ``` Change-Id: Ie86eaa60a414bb5d62f89584aa674c3b586e0516 Signed-off-by: Andrew Jeffery
