* Tell the TLMu instance that a given memory area is maps to RAM. TLMu needs to know if any of the external mappings provided by the mainĪt setup time, you'll need to tell TLMu by calling tlmu_map_ram(): Internally, TLMu differentiates pretty heavily between RAMs and other devices. Void tlmu_set_log_filename(struct tlmu *t, const char *f) * Set the per TLMu instance log filename. Logfile to avoid having the different TLMu cores stepping on each other. When using enabling execution traces, it is useful to setup a per instance Void tlmu_append_arg(struct tlmu *t, const char *arg) * Append an argument to the TLMu instances argv list. The various options are documented in XXXXXXX.
#QEMU SYSTEM C SERIES#
The QEMU argument list is created by series of calls to tlmu_append_arg. Setting various TLMu parameters and registering callbacks for the various Setting up the emulator involves configuration of the QEMU arguments, Int tlmu_load(struct tlmu *t, const char *soname) * Returns zero on success and non-zero if failing to load the The arguments areĪ pointer to a TLMu instance and the name of the emulator library Loading of an emulator is done by calling tlmu_load. Void tlmu_init(struct tlmu *t, const char *name) This can be done by simply creating one and initializing it with tlmu_init().
#QEMU SYSTEM C INSTALL#
Now install a local copy of the tlmu sdk:īefore trying the System-C example, you will need to edit Interact with a magic device that allows them to print: Three guest images are provided, -guest/guest. The examples instantiate 3 cores: a CRISv10, an ARM926 and a MIPS 24Kc. There is a simple example in pure C and another one that shows integration Libtlmu-arm.so libtlmu-cris.so libtlmu-mipsel.soĪnd also the header files needed to interface with TLMu:Īn easy way to get started is by taking a look at the examplesĭistributed with TLMu. Now you should have a TLMu lib per arch, for example: % make install-tlmu DESTDIR=/tmp/my-tlmu/ tlmu/configure -target-list=cris-softmmu,mipsel-softmmu,arm-softmmu -extra-cflags=-fPIC

If you want to save time, and only build for a subset of the archs (e.g CRIS, ARM and MIPS): tlmu/configure -extra-cflags=-fPIC -disable-strip If you want to install debug versions of TLMu, add –disable-strip to These are essentially the same as the ones for plain QEMU. To get a list of supported configuration flags, add –help to the argument % git clone git:///edgarigl/tlmu.git 3.2 ConfiguringĬreate a build directory (or build it in the src dir) and enter it: If you are reading this, you probably already cloned the git tree. Signals from the external emulator into the TLMu CPU core and write the Also, one needs to decide howto connect the interrupt I'd expect most (if not all) archs to work with little integration, but TLMu can provide per core execution traces and GDB remote access forĪt the moment, the following archs have basic support for TLMu: Different TLMu instances within an emulator can crossĪccess each others RAMs and devices (with some constrains). RAM both internal to the TLMu instance and also external (provided by the There is good flexibility in how systems can be partitioned. System can then be integrated with a system written in for example TLM-2.0. Partial system (e.g, CPU core + internal devices). TLMu can provide either only the CPU cores or it can provide a more complete In a system where RAM's are external to QEMU.The same virtual system and within the same emulator process. In a heterogeneous arch environment, e.g a MIPS and a CRIS core on.TLMu extends the QEMU emulation framework making it possible to use QEMU 4.2.14 Creating QEMU machines with TLMu support.
