mailbox: ioctl to fetch mailbox size

2021-10-19T22:10:38+00:00

The size of mailbox differ from AST2500, AST2600 A0 and A1. Add an ioctl support to fetch the mailbox size. Tested: Verfied ioctl call returns mailbox size as expected. Change-Id: I4e261aaf8aa3fb108d6ad152d30a17b114d70ccd Signed-off-by: Arun P. Mohanan

Move JTAG state matrix to JTAG core header file

2021-10-19T22:10:38+00:00

- Move TDI state matrix to core header file - These changes are done based on feedback from Paul Fertser, from the OpenOCD. Test: SPR ASD Sanity and jtag_test finished successfully. ICX ASD Sanity and jtag_test finished successfully. Change-Id: Idb612e50d5a8ea5929f7c9241d279c345587983a Signed-off-by: Castro, Omar Eduardo

ASD Prevent TDI remaining bits to be override during JTAG xfer

2021-10-19T22:10:38+00:00

JTAG xfer length is measured in bits and it is allowed to send non 8-bit aligned xfers. For such xfers we will read the content of the remaining bits in the last byte of tdi buffer and restore those bits along with the xfer readback. Add also linux types to JTAG header to remove external dependencies. Test: SPR ASD Sanity and jtag_test finished successfully. SKX ASD Sanity and jtag_test finished successfully.

aspeed-mctp: Add EID information related ioctls

2021-10-19T22:10:35+00:00

Implement two new ioctls for storing EID related information: * ASPEED_MCTP_IOCTL_GET_EID_INFO * ASPEED_MCTP_IOCTL_SET_EID_INFO Driver stores EID mapping in a list which is traversed when one tries to get information using ASPEED_MCTP_IOCTL_GET_EID_INFO ioctl, when given EID mapping is not found in the list, next entry is returned. When there are no entries with EIDs higher than specified in the IOCTL call -ENODEV is returned. Whenever new information about EID mapping is stored with ASPEED_MCTP_IOCTL_SET_EID_INFO ioctl driver empties exsiting list of mappings and creates new one based on user input. After insertion list is sorted by EID. Invalid input such as duplicated EIDs will cause driver to return -EINVAL. Signed-off-by: Karol Wachowski

soc: aspeed: mctp: Add API to register client for MCTP type

2021-10-19T22:10:35+00:00

MCTP client can register for receiving packets with selected MCTP message type or PCIE vendor defined message type. Vendor defined type is 2 bytes but in Intel VDMs the first byte is variable and only the second byte contains constant message type - to support this use case we have to specify 2 byte mask that is applied to packet type before comparing with registered vendor type. When MCTP packet arrives its header is compared with a list of registered (vendor) types. If no client registered for packet's (vendor) type then the packet is dispatched to the default client. Fragmented packets are not considered for type matching. Only one client can register for given (vendor) type. Client can register for multiple (vendor) types. All packet fields must be specified in big endian byte order. This feature allows to support multiple clients simultaneously but only one client per (vendor) message type. For example we can have PECI client in kernel that uses PECI vendor message type, dcpmm daemon in user space that handles NVDIMM vendor type messages and mctpd service that handles MCTP control and PLDM message types. tested with peci_mctp_test application Signed-off-by: Andrzej Kacprowski

soc: aspeed: mctp: Add IOCTL to register default client

2021-10-19T22:10:35+00:00

Add IOCTL to register given client as default client that receives all packets that were not dispatched to other clients. This IOCTL is intended to be used by mctpd service or test application that should receive all packets that are not claimed by other clients. mctpd service might not be the first user space client since dcpmm or telemetry client can start before mctpd or mctpd can crash and be restarted automatically at any time. To preserve backward compatibility with mctpd, the first user space client will be registered automatically as default client - once mctpd is modified to call ASPEED_MCTP_IOCTL_REGISTER_DEFAULT_HANDLER we can remove this workaround.

1. Helpers for reading/writing PCS registers added. 2. PECI sensor configuration structure definition and helpers added. 3. New PECI PCS index and parameters definitions added. Tested: * on WilsonCity platform * hwmon/peci modules work as before the change Signed-off-by: Zbigniew Lukwinski

soc: aspeed: mctp: Add initial driver for ast2600-mctp

2021-10-19T22:10:34+00:00

Currently, there is no proper MCTP networking subsystem in Linux. Until we are able to work out the details of that, we are going to expose HW to userspace using raw read/write interface. Because of that, this driver is not intended to be submitted upstream. Here we are providing a simple device driver for AST2600 MCTP controller. v2: Added workarounds for BMC reboot/reset, corrected endianess comment, changed TX_BUF_ADDR to be consistent, fixed typos. v3: Added workaround for RX hang, added swapping PCIe VDM header to network order, corrected buffer allocation size. v4: Fixed TX broken after sending 32 byte packet Signed-off-by: Iwona Winiarska Signed-off-by: Andrzej Kacprowski
