exclusive user space access (superpipe). In case a LUN is visible
across multiple ports and adapters, this ioctl is used to uniquely
identify each LUN by its World Wide Node Name (WWNN).
CXL Flash Driver Host IOCTLs
============================
Each host adapter instance that is supported by the cxlflash driver
has a special character device associated with it to enable a set of
host management function. These character devices are hosted in a
class dedicated for cxlflash and can be accessed via /dev/cxlflash/*.
Applications can be written to perform various functions using the
host ioctl APIs below.
The structure definitions for these IOCTLs are available in:
uapi/scsi/cxlflash_ioctl.h
HT_CXLFLASH_LUN_PROVISION
-------------------------
This ioctl is used to create and delete persistent LUNs on cxlflash
devices that lack an external LUN management interface. It is only
valid when used with AFUs that support the LUN provision capability.
When sufficient space is available, LUNs can be created by specifying
the target port to host the LUN and a desired size in 4K blocks. Upon
success, the LUN ID and WWID of the created LUN will be returned and
the SCSI bus can be scanned to detect the change in LUN topology. Note
that partial allocations are not supported. Should a creation fail due
to a space issue, the target port can be queried for its current LUN
geometry.
To remove a LUN, the device must first be disassociated from the Linux
SCSI subsystem. The LUN deletion can then be initiated by specifying a
target port and LUN ID. Upon success, the LUN geometry associated with
the port will be updated to reflect new number of provisioned LUNs and
available capacity.
To query the LUN geometry of a port, the target port is specified and
upon success, the following information is presented:
- Maximum number of provisioned LUNs allowed for the port
- Current number of provisioned LUNs for the port
- Maximum total capacity of provisioned LUNs for the port (4K blocks)
- Current total capacity of provisioned LUNs for the port (4K blocks)
With this information, the number of available LUNs and capacity can be
can be calculated.
HT_CXLFLASH_AFU_DEBUG
---------------------
This ioctl is used to debug AFUs by supporting a command pass-through
interface. It is only valid when used with AFUs that support the AFU
debug capability.
With exception of buffer management, AFU debug commands are opaque to
cxlflash and treated as pass-through. For debug commands that do require
data transfer, the user supplies an adequately sized data buffer and must
specify the data transfer direction with respect to the host. There is a
maximum transfer size of 256K imposed. Note that partial read completions
are not supported - when errors are experienced with a host read data
transfer, the data buffer is not copied back to the user.
