TLM-1.0 header files
|
||||
====================
|
||||
|
||||
Dir: include/tlm_core/tlm_1/
|
||||
|
||||
SubDirs: tlm_analysis/
|
||||
tlm_req_rsp/
|
||||
|
||||
Files: README.txt
|
||||
|
||||
|
||||
Comments
|
||||
========
|
||||
|
||||
User code should only #include the tlm or tlm.h header file in the include/
|
||||
directory and avoid including any of the include files in this directory
|
||||
directly. All objects defined in this file hierarchy are in the tlm namespace.
|
||||
|
||||
The header files are organizated, by subdirectory, as follows:
|
||||
|
||||
|
||||
tlm_analysis/
|
||||
--------------
|
||||
|
||||
This contains the analysis interfaces, ports, and fifos. These files were not
|
||||
part of the original TLM-1.0 release, but have been grouped with TLM-1.0 in this
|
||||
release of TLM-2.0
|
||||
|
||||
Files:
|
||||
tlm_analysis.h (includes the other header files in this directory )
|
||||
tlm_analysis_fifo.h (defines tlm_analysis_fifo )
|
||||
tlm_analysis_if.h (defines tlm_analysis_if and tlm_delayed_analysis_if )
|
||||
tlm_analysis_port.h (defines tlm_analysis_port )
|
||||
tlm_analysis_triple.h (defines tlm_analysis_triple )
|
||||
tlm_write_if.h (defines tlm_write_if and tlm_delayed_write_if )
|
||||
|
||||
|
||||
tlm_req_rsp/
|
||||
------------
|
||||
|
||||
This provides support for TLM modeling based on a request/response pair that
|
||||
are passed by value. This is the original TLM 1.0 standard, with the addition
|
||||
of an overloading of the blocking transport method with pass-by-reference arguments.
|
||||
|
||||
Files:
|
||||
tlm_req_rsp.h (includes the key header files from the other directories)
|
||||
|
||||
tlm_1_interfaces/
|
||||
tlm_core_ifs.h (defines the TLM 1.0 core interfaces:
|
||||
tlm_transport_if
|
||||
tlm_blocking_get_if

||||
tlm_fifo_debug_if
|
||||
tlm_fifo_put_if
|
||||
tlm_fifo_get_if
|
||||
tlm_fifo_config_size_if )
|
||||
tlm_master_slave_ifs.h ( defines the TLM1.0 master slave interfaces:
|
||||
tlm_blocking_master_if
|
||||
tlm_blocking_slave_if
|
||||
tlm_nonblocking_master_if
|
||||
tlm_nonblocking_slave_if
|
||||
tlm_master_if
|
||||
tlm_slave_if )
|
||||
tlm_tag.h ( defines tlm_tag )
|
||||
|

|
||||
interfaces for tlm_fifo )
|
||||
circular_buffer.h (defines circular buffer used by tlm_fifo )
|
||||
tlm_req_rsp_channels/
|
||||
tlm_req_rsp_channels.h (defines tlm_req_rsp_channel and
|
||||
tlm_transport_channel )

|

// DMI interfaces for getting and invalidating DMI pointers:
|

//////////////////////////////////////////////////////////////////////////
|
||||
|
||||
// The semantics of the forward interface are as follows:
|
||||
//
|
||||
// - An initiator that wants to get direct access to a target's memory region
|
||||
// can call the get_direct_mem_ptr method with the 'trans' parameter set to
|
||||
// the address that it wants to gain access to. It sets the trans.m_command
|
||||
// to specify if the initiator intended use (read or write)
|
||||
// to the target's DMI region. The initiator is responsible for calling the
|
||||
// method with a freshly initialized tlm_dmi object either by using a newly
|
||||
// constructed object, or by calling an existing object's init() method.
|
||||
// - Although a reference to a complete 'TRANS' type is passed to the get_
|
||||
// direct_mem_ptr call, only the address command, and extension fields are of
|
||||
// interest in most cases.
|
||||
// - Read and write ranges are not necessarily identical. If they are, a target
|
||||
// can specify that the range is valid for all accesses with the tlm_data
|
||||
// m_type attribute in the.
|
||||
// - The interconnect, if any, needs to decode the address and forward the
|
||||
// call to the corresponding target. It needs to handle the address exactly
|
||||
// as the target would expect on a transaction call, e.g. mask the address
|
||||
// according to the target's address width.
|
||||
// - If the target supports DMI access for the given address, it sets the
|
||||
// data fields in the DMI struct and returns true.
|
||||
// - If a target does not support DMI access it needs to return false.
|
||||
// The target can either set the correct address range in the DMI struct
|
||||
// to indicate the memory region where DMI is disallowed, or it can specify
|
||||
// the complete address range if it doesn't know it's memory range. In this
|
||||
// case the interconnect is responsible for clipping the address range to
|
||||
// the correct range that the target serves.
|
||||
// - The interconnect must always translate the addresses to the initiator's
|
||||
// address space. This must be the inverse operation of what the
|
||||
// interconnect needed to do when forwarding the call. In case the
|
||||
// component wants to change any member of the tlm_dmi object, e.g. for
|
||||
// its own latency to the target's latency, it must only do so *after* the
|
||||
// target has been called. The target is always allowed to overwrite all
|
||||
// values in the tlm_dmi object.
|
||||
// - In case the slave returned with an invalid region the bus/interconnect
|
||||
// must fill in the complete address region for the particular slave in the
|
||||
// DMI data structure.
|
||||
//
|
||||
// DMI hint optimization:
|
||||
//
|
||||
// Initiators may use the DMI hint in the tlm_generic_payload to avoid
|
||||
// unnecessary DMI attempts. The recommended sequence of interface
|
||||
// method calls would be:
|
||||
//
|
||||
// - The initiator first tries to check if it has a valid DMI region for the
|
||||
// address that it wants to access next.
|
||||
// - If not, it performs a normal transaction.
|
||||
// - If the DMI hint in this transaction is true, the initiator can try and
|
||||
// get the DMI region.
|
||||
//
|
||||
// Note that the DMI hint optimization is completely optional and every
|
||||
// initiator model is free to ignore the DMI hint. However, a target is
|
||||
// required to set the DMI hint to true if a DMI request on the given address
|
||||
// with the given transaction type (read or write) would have succeeded.

|

// - An interconnect component or a target is required to invalidate all

// affected DMI regions whenever any change in the regions take place.

|
||||
// that it already reported, if it would answer the same DMI request
|
||||
// with any member of the tlm_dmi data structure set differently.
|
||||
// - An interconnect component must forward the invalidate_direct_mem_ptr call
|
||||
// to all initiators that could potentially have a DMI pointer to the region
|
||||
// specified in the method arguments. A safe implementation is to call
|
||||
// every attached initiator.
|
||||
// - An interconnect component must transform the address region of an
|
||||
// incoming invalidate_direct_mem_ptr to the corresponding address space
|
||||
// for the initiators. Basically, this is the same address transformation
|
||||
// that the interconnect does on the DMI ranges on the forward direction.
|
||||
// - Each initiator must check if it has a pointer to the given region and
|
||||
// throw this away. It is recommended that the initiator throws away all DMI
|
||||
// regions that have any overlap with the given regions, but this is not a
|
||||
// hard requirement.
|
||||
//
|
||||
// - A full DMI pointer invalidation, e.g. for a bus remap can be signaled
|
||||
// by setting the range: 0x0 - 0xffffffffffffffffull = (sc_dt::uint64)-1
|
||||
// - An initiator must throw away all DMI pointers in this case.
|

//

// from within the invalidate_direct_mem_ptr method, directly or indirectly.

Tranaction-Level Modelling

Endianness Helper Functions
|

|
||||
DESCRIPTION
|
||||
A set of functions for helping users to get the endianness
|
||||
right in their TLM models of system initiators. These functions are
|
||||
for use within an initiator. They can not be used as-is outside
|
||||
an initiator because the extension used to store context will not work
|
||||
if cascaded, and they do not respect the generic payload mutability
|
||||
rules. However this code may be easily copied and adapted for use
|
||||
in bridges, etc..
|
||||
|
||||
These functions are not compulsory. There are other legitimate ways to
|
||||
achieve the same functionality. If extra information is available at
|
||||
compile time about the nature of an initiator's transactions, this can
|
||||
be exploited to accelerate simulations by creating further functions
|
||||
similar to those in this file. In general a functional transaction can be
|
||||
described in more than one way by a TLM-2 GP object.
|
||||
|
||||
The functions convert the endianness of a GP object, either on request or
|
||||
response. They should only be used when the initiator's endianness
|
||||
does not match the host's endianness. They assume 'arithmetic mode'
|
||||
meaning that within a data word the byte order is always host-endian.
|
||||
For non-arithmetic mode initiators they can be used with a data word
|
||||
size of 1 byte.
|
||||
|
||||
All the functions are templates, for example:
|
||||
|
||||
template<class DATAWORD> inline void
|
||||
to_hostendian_generic(tlm_generic_payload *txn, int sizeof_databus)
|
||||
|
||||
The template parameter provides the data word width. Having this as a class
|
||||
makes it easy to use it for copy and swap operations within the functions.
|
||||
If the assignment operator for this class is overloaded, the endianness
|
||||
conversion function may not have the desired effect.
|
||||
|
||||
All the functions have the same signature except for different names.
|
||||
|
||||
The principle is that a function to_hostendian_convtype() is called when the
|
||||
initiator-endian transaction is created, and the matching function
|
||||
from_hostendian_convtype() is called when the transaction is completed, for
|
||||
example before read data can be used. In some cases the from_ function is
|
||||
redundant but an empty function is provided anyway. It is strongly
|
||||
recommended that the from_ function is called, in case it ceases to be
|
||||
redundant in future versions of this code.
|
||||
|
||||
No context needs to be managed outside the two functions, except that they
|
||||
must be called with the same template parameter and the same bus width.
|
||||
|
||||
For initiator models that can not easily manage this context information,
|
||||
a single entry point for the from_ function is provided, which will be
|
||||
a little slower than calling the correct from_ function directly, as
|
||||
it can not be inlined.
|
||||
|
||||
All functions assume power-of-2 bus and data word widths.
|
||||
|
||||
Functions offered:
|
||||
|
||||
0) A pair of functions that work for almost all TLM2 GP transactions. The
|
||||
only limitations are that data and bus widths should be powers of 2, and that
|
||||
the data length should be an integer number of streaming widths and that the
|
||||
streaming width should be an integer number of data words.
|
||||
These functions always allocate new data and byte enable buffers and copy
|
||||
data one byte at a time.
|
||||
tlm_to_hostendian_generic(tlm_generic_payload *txn, int sizeof_databus)
|
||||
tlm_from_hostendian_generic(tlm_generic_payload *txn, int sizeof_databus)
|
||||
|
||||
1) A pair of functions that work for all transactions regardless of data and
|
||||
bus data sizes and address alignment except for the the following
|
||||
limitations:
|
||||
- byte-enables are supported only when byte-enable granularity is no finer
|
||||
than the data word (every data word is wholly enabled or wholly disabled)
|
||||
- byte-enable-length is not supported (if byte enables are present, the byte
|
||||
enable length must be equal to the data length).
|
||||
- streaming width is not supported
|
||||
- data word wider than bus word is not supported
|
||||
A new data buffer and a new byte enable buffer are always allocated. Byte
|
||||
enables are assumed to be needed even if not required for the original
|
||||
(unconverted) transaction. Data is copied to the new buffer on request
|
||||
(for writes) or on response (for reads). Copies are done word-by-word
|
||||
where possible.
|
||||
tlm_to_hostendian_word(tlm_generic_payload *txn, int sizeof_databus)
|
||||
tlm_from_hostendian_word(tlm_generic_payload *txn, int sizeof_databus)
|
||||
|
||||
2) If the original transaction is both word and bus-aligned then this pair of
|
||||
functions can be used. It will complete faster than the generic function
|
||||
because the data reordering function is much simpler and no address
|
||||
conversion is required.
|
||||
The following limitations apply:
|
||||
- byte-enables are supported only when byte-enable granularity is no finer
|
||||
than the data word (every data word is wholly enabled or wholly disabled)
|
||||
- byte-enable-length is not supported (if byte enables are present, the byte
|
||||
enable length must be equal to the data length).
|
||||
- streaming width is not supported
|
||||
- data word wider than bus word is not supported
|
||||
- the transaction must be an integer number of bus words
|
||||
- the address must be aligned to the bus width
|
||||
tlm_to_hostendian_aligned(tlm_generic_payload *txn, int sizeof_databus)
|
||||
tlm_from_hostendian_aligned(tlm_generic_payload *txn, int sizeof_databus)
|
||||
|
||||
3) For single word transactions that don't cross a bus word boundary it
|
||||
is always safe to work in-place and the conversion is very simple. Again,
|
||||
streaming width and byte-enable length are not supported, and byte-enables
|
||||
may not changes within a data word.
|
||||
tlm_to_hostendian_single(tlm_generic_payload *txn, int sizeof_databus)
|
||||
tlm_from_hostendian_single(tlm_generic_payload *txn, int sizeof_databus)
|
||||
|
||||
4) A single entry point for accessing the correct from_ function without
|
||||
needing to store context.

Comments
|
||||
========
|
||||
|
||||
This directory contains a number of ease-of-use and convenience implementations
|
||||
for the interoperability standard. All objects defined in the header files of
|
||||
this directory are contained in the tlm_util namespace.
|
||||
There is no tlm_utils.h header files containing all includes in order to avoid
|
||||
additional dependencies for TLM 2.0
|
||||
|
||||
Files:
|
||||
simple_initiator_socket.h
|
||||
version of an initiator socket that has a default implementation of all
|
||||
interfaces and allows to register an implementation for any of the
|
||||
interfaces to the socket, either unique interfaces or tagged interfaces
|
||||
(carrying an additional id)
|
||||
|
||||
simple_target_socket.h
|
||||
version of a target socket that has a default implementation of all
|
||||
interfaces and allows to register an implementation for any of the
|
||||
interfaces to the socket, either unique interfaces or tagged interfaces
|
||||
(carrying an additional id)
|
||||
This socket allows to register only 1 of the transport interfaces
|
||||
(blocking or non-blocking) and implements a conversion in case the
|
||||
socket is used on the other interface
|
||||
|
||||
passthrough_target_socket.h
|
||||
version of a target socket that has a default implementation of all
|
||||
interfaces and allows to register an implementation for any of the
|
||||
interfaces to the socket.
|
||||
|
||||
multi_passthrough_initiator_socket.h
|
||||
an implementation of a socket that allows to bind multiple targets to the
|
||||
same initiator socket. Implements a mechanism to allow to identify in the
|
||||
backward path through which index of the socket the call passed through
|
||||
|
||||
multi_passthrough_target_socket.h
|
||||
an implementation of a socket that allows to bind multiple initiators to
|
||||
the same target socket. Implements a mechanism to allow to identify in the
|
||||
forward path through which index of the socket the call passed through
|
||||
|
||||
multi_socket_bases.h
|
||||
contains base class definitions used by the multi_passthrough sockets
|
||||
|
||||
peq_with_get.h
|
||||
payload event queue (PEQ) implementation using a pull interface.
|
||||
Has a get_next_transaction API that returns the transaction that is
|
||||
scheduled in the event queue
|
||||
|
||||
peq_with_cb_and_phase.h
|
||||
another payload event queue, this one with a push interface (callback
|
||||
mechanism ). Allows to register a callback that will be called whenever
|
||||
the event in the event queue is triggered, the callback gets transaction
|
||||
and phase as arguments
|
||||
|
||||
instance_specific_extensions.h
|
||||
is an implementation for adding extentions in the generic payload that
|
||||
are specific to an instance along the path of a transaction, to allow that
|
||||
extentions of the same type can be used by the different blocks along
|
||||
the path of the transaction
|
||||
|
||||
tlm_quantumkeeper.h
|
||||
is an convenience object used to keep track of the local time in
|
||||
an initiator (how much it has run ahead of the SystemC time), to
|
||||
synchronize with SystemC time etc.

/*
|
||||
Instance specific extensions, are extension that only a single instance of a module
|
||||
may access. They are invisible to all other modules; they are private to this
|
||||
instance so to speak.
|
||||
|
||||
As they are only of value to a certain instance, this instance knows very well
|
||||
when it needs them and when it does not need them any longer (usually when
|
||||
a transaction passes through a module for the last time).
|
||||
It does not have to care if anyone else in the system may still have a
|
||||
reference to the transaction as this one is not able to access the extension
|
||||
anyway.
|
||||
Therefore the instance is obliged to call set_extension when it wants to add a
|
||||
private extension and clear_extension when it does not need it any more.
|
||||
|
||||
To get access to an instance specifc extension the module must own a so called
|
||||
instance_specific_extension_accessor that provides the exclusive access rights.
|
||||
Assuming the instance_specific_extension_accessor of a given module is called m_accessor
|
||||
and the transaction of which the private extension is about to be accessed
|
||||
is called txn, then the calls have to be
|
||||
|
||||
m_accessor(txn).set_extension(...);
|
||||
or
|
||||
m_accessor(txn).clear_extension(...);
|
||||
|
||||
The owner of the private extension is responsible to allocate/deallocate
|
||||
the extension before/after setting/clearing the extension.
