eth: fbnic: add OTP health reporter

2025-09-18T09:37:23Z

OTP memory ("fuses") are used for secure boot and anti-rollback protection. The OTP memory is ECC protected. Check for its health periodically to notice when the chip is starting to go bad.

eth: fbnic: add FW health reporter

2025-09-18T09:37:23Z

Add a health reporter to catch FW crashes. Dumping the reporter if FW has not crashed will create a snapshot of FW memory.

eth: fbnic: rename fbnic_fw_clear_cmpl to fbnic_mbx_clear_cmpl

2025-06-26T12:56:14Z

fbnic_fw_clear_cmpl() does the inverse of fbnic_mbx_set_cmpl(). It removes the completion from the mailbox table. It also calls fbnic_mbx_set_cmpl_slot() internally. It should have fbnic_mbx prefix, not fbnic_fw. I'm not very clear on what the distinction is between the two prefixes but the matching "set" and "clear" functions should use the same prefix. While at it move the "clear" function closer to the "set".

2025-05-15T10:59:18Z

Add support to update the CMRT and control firmware as well as the UEFI driver on fbnic using devlink dev flash. Make sure the shutdown / quiescence paths like suspend take the devlink lock to prevent them from interrupting the FW flashing process.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

eth: fbnic: Add devlink firmware version info

2024-09-10T10:00:19Z

This adds support to show firmware version information for both stored and running firmware versions. The version and commit is displayed separately to aid monitoring tools which only care about the version.

eth: fbnic: Add L2 address programming

2024-07-15T19:50:44Z

Program the Rx TCAM to control L2 forwarding. Since we are in full control of the NIC we need to make sure we include BMC forwarding in the rules. When host is not present BMC will program the TCAM to get onto the network but once we take ownership it's up to Linux driver to make sure BMC L2 addresses are handled correctly.

eth: fbnic: Add register init to set PCIe/Ethernet device config

2024-07-15T19:50:42Z

As a part of enabling the device the first step is to configure the AXI and Ethernet interfaces to allow for basic traffic. This consists of configuring several registers related to the PCIe and Ethernet FIFOs as well as configuring the handlers for moving traffic between entities.
