15.2 Creating Errors in Structures

There are several ways of inserting various errors in the NVMe and AHCI/ATA structures

- Using “Field” construct to set non-zero values to reserved fields.

The “Field” directive (described in 3.1) can be used to set non zero values in reserved fields within first 8

DWORDs of any structure:

Structure=NVMe

{

Location=Mem64

Offset = 0

NVMeStructType=AdminCommand

OpcodeAdmin = ADMIN_IDENTIFY

PRP1_Low = 0x3F25B190

PRP1_High = 0x8

PRP2_Low = 0x3F25C000

PRP2_High = 0x8

CNS = Controller

Field[63:71] = 0xA5 ; setting non-zero value of a reserved byte in Command DW 2

}

- Assigning undefined values to structure fields.

A numeric value can be assigned to any of the defined structure fields that is undefined or invalid:

Structure=AHCI

{

Location=Mem64

Offset = 0x1000

AhciStructType=FIS

FISType = 0x15 ; undefined FIS type instead of RegisterH2D

Features = 0x02

ATACommand = SET_FEATURES

C = Yes

Device = 0xA0

}

- Using AddressSpace=Write to supply raw byte image of the structure with any contents desired.\

As before Structure command was implemented, AddressSpace=Write can be used to place the byte

stream of the desired structure in the Host Memory Region. This way any byte image of a structure can

be programmed, creating any type of error desired.
