cache

Format

The format for the cache command is:

cache  [-idvl][set [adr]]

where:

-i

is a flag indicating that the Icache should be displayed.

-d

is a flag indicating that the Dcache should be displayed (default).

-v

is a flag indicating that only valid entries should be displayed.

-l

is a flag indicating that only locked entries should be displayed (400x cores only).

set

is the set number, eg. 0 or 1 for set0 and set1 respectively (default is set0).

adr

is the address of the first cache entry to be displayed.

By default, the cache command displays the first 8 lines of set0 of the Dcache.

Functional Description

The cache command displays the contents of the caches. If the user does not specify the starting address adr or set number, display starts at address zero. Note that, because PMON generally executes from cache, the values displayed by this command will change even though no user application has been executed. With IMON this restriction is avoided.

If the user specifies the -i option, the contents of the Icache will be displayed, otherwise the Dcache will be displayed. If set is specified, the command will display the contents of the specified cache set. If adr is specified, the display will start at that address.

Examples illustrating the use of the cache command follow.

PMON> cache			Display Dcache set0 starting at 
                                address zero.

PMON> cache 1 80020000		Display Dcache set 1 starting at
				address 0x80020000.

PMON> cache -i 0 80020000	Display Icache set 0 starting at
				address 0x80020000.
