Class Hierarchy

conf-object → log-object → logical-memory-translator

Interfaces Implemented

log_object

Description

Keeps track of all translations inserted in the MMUs of the cpus listed in cpu_list, unless they are specifically marked invalid and flushed. The translations gathered allow access to virtual memory areas that are not currently present in the TLBs. The only architecture supported by this class is SPARCv9.

Attribute List

cpu_list

Required attribute; read/write access; type: [o*].

List of cpus for which TLB events are recorded in the LMT.

data_translations

Optional attribute; read/write access; type: [[[o,i][[iii]*]]*].

Data translations present in the LMT. The format of the returned value is [[[mmu_object, context number], [[page_logical_address, log2_of_page_size, page_physical_address], [-another page-], ...]], -other (mmu, context) information-, ...].

instruction_translations

Optional attribute; read/write access; type: [[[o,i],[[iii]*]]*].

Instruction translations present in the LMT. The format of the returned value is [[[mmu_object, context number], [[page_logical_address, log2_of_page_size, page_physical_address], [-another page-], ...]], -other (mmu, context) information-, ...].

Command List

Commands defined by interface log_object

log, log-group, log-level, log-size, log-type

Commands

disassemble	disassemble instructions using the LMT translations
get	get memory value using the LMT translations
logical-to-physical	translate virtual address using the LMT translations
set	set a value in memory using the LMT translations
x	examine raw memory contents using the LMT translations

Command Descriptions

<logical-memory-translator>.disassemble

Alias

<logical-memory-translator>.da

Synopsis

<logical-memory-translator>.disassemble cpu-name address [context] [count]

Description

Use the LMT translations to disassemble count instructions starting from the virtual address address, for the cpu cpu-name and the context context. Note that this command can not disassemble across page boundaries.

<logical-memory-translator>.get

Synopsis

<logical-memory-translator>.get cpu-name address [size] [context] ["type"] [-l] [-b]

Description

Use the LMT translations to get the value present at the virtual address address with a size of size, for the cpu cpu-name and the context context, looking from translations in the type TLB (either data or instruction). The -l flag sets little-endian semantics, while the -b flag sets big-endian semantics. If none is given, the endianness of cpu-name is used. Note that this command can not get values across page boundaries.

<logical-memory-translator>.logical-to-physical

Alias

<logical-memory-translator>.l2p

Synopsis

<logical-memory-translator>.logical-to-physical cpu-name address [context] ["type"]

Description

Use the LMT translations to translate the virtual address address, for the cpu cpu-name and the context context, looking from translations in the type TLB (either data or instruction).

<logical-memory-translator>.set

Synopsis

<logical-memory-translator>.set cpu-name address value [size] [context] ["type"] [-l] [-b]

Description

Use the LMT translations to set the value value with a size of size at the virtual address address, for the cpu cpu-name and the context context, looking from translations in the type TLB (either data or instruction). The -l flag sets little-endian semantics, while the -b flag sets big-endian semantics. If none is given, the endianness of cpu-name is used. Note that this command can not set values across page boundaries.

<logical-memory-translator>.x

Synopsis

<logical-memory-translator>.x cpu-name address [context] ["type"] [size]

Description

Use the LMT translation to print out the contents of the memory area defined by the start virtual address address and the size size for the cpu cpu-name in the context context, looking from translations in the type TLB (either data or instruction). Note that this command does not handle areas that cross page boundaries.
