b3c8eb50 - ibft: Expose iBFT acpi header via sysfs

Thu, 24 Mar 2016 01:49:26 +0000

ibft: Expose iBFT acpi header via sysfsSome ethernet adapter vendors are supplying products which support optional(payed license) features. On some adapters this includes a hardware iscsiinitiator. The same adapters in a normal (no extra licenses) mode ofoperation can be used as a software iscsi initiator. In addition, softwareiscsi boot initiators are becoming a standard part of many vendors uefiimplementations. This is creating difficulties during early boot/installdetermining the proper configuration method for these adapters when theyare used as a boot device.The attached patch creates sysfs entries to expose information from theacpi header of the ibft table. This information allows for a method toeasily determining if an ibft table was created by a ethernet card'sfirmware or the system uefi/bios. In the case of a hardware initiator thisinformation in combination with the pci vendor and device id can be usedto ascertain any vendor specific behaviors that need to be accommodated.Reviewed-by: Lee Duncan Signed-off-by: David Bond Signed-off-by: Konrad Rzeszutek Wilk List of files: /linux-6.15/Documentation/ABI/testing/sysfs-ibft

138fe4e0 - Firmware: add iSCSI iBFT Support

Thu, 10 Apr 2008 02:50:41 +0000

Firmware: add iSCSI iBFT SupportAdd /sysfs/firmware/ibft/[initiator|targetX|ethernetX] directories along withtext properties which export the the iSCSI Boot Firmware Table (iBFT)structure.What is iSCSI Boot Firmware Table? It is a mechanism for the iSCSI tools toextract from the machine NICs the iSCSI connection information so that theycan automagically mount the iSCSI share/target. Currently the iSCSIinformation is hard-coded in the initrd. The /sysfs entries are read-onlyone-name-and-value fields.The usual set of data exposed is:# for a in `find /sys/firmware/ibft/ -type f -print`; do echo -n "$a: "; cat $a; done/sys/firmware/ibft/target0/target-name: iqn.2007.com.intel-sbx44:storage-10gb/sys/firmware/ibft/target0/nic-assoc: 0/sys/firmware/ibft/target0/chap-type: 0/sys/firmware/ibft/target0/lun: 00000000/sys/firmware/ibft/target0/port: 3260/sys/firmware/ibft/target0/ip-addr: 192.168.79.116/sys/firmware/ibft/target0/flags: 3/sys/firmware/ibft/target0/index: 0/sys/firmware/ibft/ethernet0/mac: 00:11:25:9d:8b:01/sys/firmware/ibft/ethernet0/vlan: 0/sys/firmware/ibft/ethernet0/gateway: 192.168.79.254/sys/firmware/ibft/ethernet0/origin: 0/sys/firmware/ibft/ethernet0/subnet-mask: 255.255.252.0/sys/firmware/ibft/ethernet0/ip-addr: 192.168.77.41/sys/firmware/ibft/ethernet0/flags: 7/sys/firmware/ibft/ethernet0/index: 0/sys/firmware/ibft/initiator/initiator-name: iqn.2007-07.com:konrad.initiator/sys/firmware/ibft/initiator/flags: 3/sys/firmware/ibft/initiator/index: 0For full details of the IBFT structure please take a look at:ftp://ftp.software.ibm.com/systems/support/system_x_pdf/ibm_iscsi_boot_firmware_table_v1.02.pdf[akpm@linux-foundation.org: fix build]Signed-off-by: Konrad Rzeszutek Cc: Mike Christie Cc: Peter Jones Cc: James Bottomley Cc: Ingo Molnar Cc: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/Documentation/ABI/testing/sysfs-ibft
