// SET THE DEFAULT FASTMODELS PARAMETERS
//
// 1. Replace the string with the absolute path of the FastModel executable
// e.g. string model = "/home/working_dir/RTSM_VE_Cortex-A15x1-A7x1";
string model = "<path to the model>";
// 2. Replace the string with the absolute path of the Virutalizer+Payload software
// image e.g. string app = "/home/working_dir/bootwrapper/img.axf".
string app = "<path to the software image>";
// 3. Replace the string with the absolute path of the wboot.bin image created in
// the bootwrapper/big-little directory. This image is load in flash at 0x0
// and distinguishes between a warm and a cold reset.
string wboot = "<path to warm reset handler image>";
// 4. Invoke the FastModel with support for networking enabled.
string networking = " -C motherboard.hostbridge.userNetworking=1 -C motherboard.hostbridge.userNetPorts=\"8080=8080\" -C motherboard.smsc_91c111.enabled=1";
// 5. Additional parameters to improve FastModels performance.
string console = " -C motherboard.pl011_uart0.untimed_fifos=1 -C motherboard.pl011_uart1.untimed_fifos=1 -C motherboard.pl011_uart2.untimed_fifos=1 -C motherboard.pl011_uart3.untimed_fifos=1";
// 6. Select which cluster (Boot Cluster mentioned in "docs/01-Usage.txt")
// will come out of reset on power-on: 0x1 for for primary cluster
// (Cortex-A15, default); 0x2 for secondary cluster (Cortex-A7).
string dualcluster = " -C coretile.dualclustersystemconfigurationblock.CFG_ACTIVECLUSTER=0x1";
// INCLUDE OPTIONAL FASTMODELS PARAMETERS
//
// 1. Using the Generic Trace plugin
//
// Uncomment the next 4 'string' variables and update them _only_ if the run
// is required to generate trace output as described in
// docs/04-Cache-hit-rate-howto.txt. Also, ensure that the 4 string variables
// are appended to the system() command invocation below. Each 'trace'
// parameter is described below.
//
// a. Add the path to the trace plugin
// string trace_plugin = " --trace-plugin <path to>/GenericTrace.so";
//
// b. Add parameters for selecting the trace sources to monitor outbound cache
// hits
// string trace_sources = " --parameter TRACE.GenericTrace.trace-sources=\*sw_trace_event\*,\*read_for_3_came_from_snoop\*,\*read_for_4_came_from_snoop\* ";
//
// c. Add the path to the trace file where all the output will be collected
// string trace_file = " --parameter TRACE.GenericTrace.trace-file=<path to trace file> ";
//
// d. Add miscellaneous parameters. The frequency at which the performance
// metrics of the model appear in the trace source can be changed here
// (default is 0x100).
// string trace_misc = " -C TRACE.GenericTrace.perf-period=0x100 -C TRACE.GenericTrace.flush=1 ";
//
// 2. Using MMC emulation
//
// Uncomment the 'mmcimage' string variable _only_ if a run is needed using
// an optional rootfs MMC image built using the instructions in
// docs/06-Optional-rootfs-build.txt. Also ensure that the 'mmcimage' string
// variable is appended to the system() command invocation below.
// string mmcimage = " -C motherboard.mmc.p_mmc_file=<path to mmc.img>";
// START FASTMODEL EXECUTION & SET BREAKPOINTS
//
// Invoke the model using the system(0 command below. It then listens for
// connection requests from the model debugger Vanilla invocation of the
// model. Append the string variables for optional parameters to the
// system() command.
system(model + " -C motherboard.flashloader0.fname=" + wboot + " -C coretile.cache_state_modelled=1" + " -a coretile.cluster0.\*=" + app + " -a coretile.cluster1.\*=" + app + networking + console + dualcluster +" --verbose -S &");
// Wait for the model to load before connecting to it. There will be times when we
// try connecting before the model has loded resulting in a "Connection refused"
// error. Increasing 'ctr' or retrying should solve the problem.
int ctr = 0;
while(ctr < 400000000)
{
ctr++;
}
// Model listens at port 7000
connectToModel("7000");
// The following lines can be uncommented to set any breakpoints on each cluster
selectTarget("coretile.cluster0.cpu0");
//bpAdd(<address>, "Normal");
//bpAdd(<address>, "Secure");
selectTarget("coretile.cluster1.cpu0");
//bpAdd(<address>, "Normal");
