History
Dave Jiang 7f5933f81b x86/asm: Add an enqcmds() wrapper for the ENQCMDS instruction 
Currently, the MOVDIR64B instruction is used to atomically submit
64-byte work descriptors to devices. Although it can encounter errors
like device queue full, command not accepted, device not ready, etc when
writing to a device MMIO, MOVDIR64B can not report back on errors from
the device itself. This means that MOVDIR64B users need to separately
interact with a device to see if a descriptor was successfully queued,
which slows down device interactions.

ENQCMD and ENQCMDS also atomically submit 64-byte work descriptors
to devices. But, they *can* report back errors directly from the
device, such as if the device was busy, or device not enabled or does
not support the command. This immediate feedback from the submission
instruction itself reduces the number of interactions with the device
and can greatly increase efficiency.

ENQCMD can be used at any privilege level, but can effectively only
submit work on behalf of the current process. ENQCMDS is a ring0-only
instruction and can explicitly specify a process context instead of
being tied to the current process or needing to reprogram the IA32_PASID
MSR.

Use ENQCMDS for work submission within the kernel because a Process
Address ID (PASID) is setup to translate the kernel virtual address
space. This PASID is provided to ENQCMDS from the descriptor structure
submitted to the device and not retrieved from IA32_PASID MSR, which is
setup for the current user address space.

See Intel Software Developer’s Manual for more information on the
instructions.

 [ bp:
   - Make operand constraints like movdir64b() because both insns are
     basically doing the same thing, more or less.
   - Fixup comments and cleanup. ]
