peci: busses: add PECI o. MCTP o. I3C platform driver

2022-06-01T08:46:09+00:00

Add PECI adapter that allows to send MCTP PCI VDM packets via i3c-mctp driver. Signed-off-by: Oleksandr Shulzhenko

peci: core: Use "domain" of-property

2022-05-23T12:06:36+00:00

peci_client can be created dynamically using sysfs API or during build time using DTS. Let's use extended DTS properties to create peci_client corresponding to specific Domain ID. Signed-off-by: Iwona Winiarska

peci: Extend peci client with Domain ID information

2022-05-23T12:06:36+00:00

Since PECI Target addressing has been changed to use Domain ID information, each peci_client instance should correspond with both CPU ID and Domain ID. Let's extend peci_client structure, sysfs API and intel-peci-client to use Domain ID. Make MFD device ID as a combination of peci adapter number, CPU ID and Domain ID. Signed-off-by: Iwona Winiarska

peci: core: Check PECI address immediately

2022-05-23T12:06:36+00:00

PECI address parameter provided to create peci_client instance is not validated in the function that handles data passed from userspace or DTS, it is only done later on in peci_new_device(). Let's move PECI address verification before peci_new_device() is called. Signed-off-by: Iwona Winiarska

peci: mctp: Remove useless class specifier

2022-05-23T08:53:13+00:00

Remove "static" specifier for mctp_peci_vdm_hdr struct declaration to fix compilation warning: drivers/peci/busses/peci-mctp.c:45:1: warning: useless storage class specifier in empty declaration 45 | } __packed; | ^ Fixes: 00037aaa6440 ("peci: mctp: Add peci-mctp adapter") Signed-off-by: Iwona Winiarska

peci: mctp: Add DomainId support for peci-mctp

2022-04-15T07:15:51+00:00

Get DomainId from peci subsystem message to send message to requested EID. Required EID is taken from aspeed-mctp based on the discovery performed by user-space application. For each particular agent behind master, information about its BDF/DomainId is sufficient to get its EID. Signed-off-by: Krzysztof Richert

peci: add domain ID support to the PECI commands

2022-03-10T21:27:19+00:00

It's possible that a PECI command can be sent in the old format without a domain ID. This uses the IOCTL size as a message length and compares it to the size of the new struct with the domain ID. If the sizes match, then the domain ID is provided; otherwise, it is set to 0. Signed-off-by: Jason M. Bills

peci: add msg_len to peci_command

2022-03-10T21:27:19+00:00

To support the new domain ID, we need to include an extra byte from userspace. This adds a length to the peci_command function so we can detect when the domain ID is sent from userspace. Signed-off-by: Jason M. Bills

peci: aspeed: Improve workaround for controller hang

2022-02-08T17:27:14+00:00

When processing PECI transaction, observing any HW state different than "idle" means that PECI controller won't be able to send PECI commands. When that occurs, attempting to reinitialize the HW by writing registers is not enough in some cases, and actual reset needs to be involved. Fixes: 20b020c06aa9 ("peci: aspeed: add a WA to cover timing negotiation issue") Signed-off-by: Iwona Winiarska

peci: mctp: Add packet dump

2021-12-15T11:10:54+00:00

Currently, there is no way to view PECI over MCTP transmit or receive data. To simplify peci-mctp debugging, let's add debug level logging for tx and rx packets. Signed-off-by: Iwona Winiarska Change-Id: Ia746ae72f37c06e9a2647b4568e9aa6c5be76f76
