Subcommands for the KDB Kernel Debugger and kdb Command

View a list of the KDB Kernel Debug Subcommands grouped by:

Introduction to Subcommands

Numeric Values

Numeric arguements for the subcommands presented in this section are required to be hexadecimal, except for arguments that specify slot numbers and arguments to the dcal subcommand. Slot numbers and arguements for the dcal subcommand must be decimal values.

Registers

Register values may be referenced by the KDB Kernel Debugger and kdb command. Register values may be used in subcommands by preceding the register name with an "@" character. This character is also used to deference addresses as explained later. The list of registers that may be referenced include:

asr Address space register
cr Condition register
ctr Count register
dar Data address register
dec Decrementer
dsisr Data storage interrupt status register
fp0-fp31 Floating point registers 0 through 31.
fpscr Floating point status and control register
iar Instruction address register
lr Link register
mq Multiply quotient
msr Machine State register
r0-r31 General Purpose Registers 0 through 31
rtcl Real Time clock (nanoseconds)
rtcu Real Time clock (seconds)
s0-s15 Segment registers.
sdr0 Storage description register 0
sdr1 Storage description register 1
srr0 Machine status save/restore 0
srr1 Machine status save/restore 1
tbl Time base register, lower
tbu Time base register, upper
tid Transaction register (fixed point)
xer Exception register (fixed point)

Other special purposes registers that may be referenced, if supported on the hardware, include: sprg0, sprg1, sprg2, sprg3, pir, fpecr, ear, pvr, hid0, hid1, iabr, dmiss, imiss, dcmp, icmp, hash1, hash2, rpa, buscsr, l2cr, l2sr, mmcr0, mmcr1, pmc1-pmc8, sia, and sda.

Expressions

The KDB Kernel Debugger and kdb command do not provide full expression processing. Expressions can only contain symbols, hex constants, references to register or memory locations, and operators. Furthermore, symbols are only allowed as the first operand of an expression. Supported operators include:

+ Addition
- Subtraction
* Multiplication
/ Division
@ Dereferencing

The dereference operator indicates that the value at the location indicated by the next operand is to be used in the calculation of the expression. For example, @f000 would indicate that the value at address 0x0000f000 should be used in evaluation of the expression. The dereference operator is also used to access the contents of register. For example, @r1 references the contents of general purpose register 1. Recursive dereferencing is allowed. As an example, @@r1 references the value at the address pointed to by the value at the address contained in general purpose register 1.

Expressions are processed from left to right only. There is no operator precedence.

Examples

Valid Expressions Results
dw @r1 displays data at the location pointed to by r1
dw @@r1 displays data at the location pointed to by value at location pointed to by r1
dw open displays data at the address beginning of the open routine
dw open+12 displays data twelve bytes past the beginning of the open routine
Invalid Expressions Problem
dw @r1+open symbols can only be the first operand
dw r1 must include @ to reference the contents of r1, if a symbol r1 existed this would be valid
dw @r1+(4*3) parentheses are not supported

Subcommand Arguments

The following table describes the most common argument types referenced in the subcommand syntax diagrams that follow.
