 145 \&\fBswtpm_ioctl [\s-1COMMAND\s0] <device>\fR

 147 .IX Header "DESCRIPTION"
 148 \&\fBswtpm_ioctl\fR implements a client tool for controlling the
 149 \&\fIswtpm_cuse\fR \s-1TPM\s0 software emulator, such as for example its
 150 initialization and shutdown. Once the swtpm_cuse has been
 151 initialized, \s-1TPM\s0 commands can be sent to it.
 152 .PP
 153 The full path to the swtpm_cuse's character device must be provided such
 154 as for example /dev/vtpm\-200.
 155 .PP
 156 The following commands are supported:
 157 .IP "\fB\-c\fR" 4
 158 .IX Item "-c"
 159 Get the swtpm_cuse's capability flags indicating which commands
 160 are supported.
 161 .IP "\fB\-i\fR" 4
 162 .IX Item "-i"
 163 Send a hardware initialization signal to the swtpm_cuse. Volatile
 164 state previously written by the \s-1TPM\s0 will be read and the file automatically
 165 delete.
 166 .IP "\fB\-s\fR" 4
 167 .IX Item "-s"
 168 Gracefully shut the swtpm_cuse down.
 169 .IP "\fB\-e\fR" 4
 170 .IX Item "-e"
 171 Get the tpmEstablished bit.
 172 .IP "\fB\-l locality\fR" 4
 173 .IX Item "-l locality"
 174 Set the locality for the subsequent \s-1TPM\s0 commands.
 175 .IP "\fB\-v\fR" 4
 176 .IX Item "-v"
 177 Have the \s-1TPM\s0 write the volatile state to a file. Upon a TPM_Init (\-i) the
 178 \&\s-1TPM\s0 state will be read and the \s-1TPM\s0 can then resume operation without further
 179 intialization.
 180 .IP "\fB\-C\fR" 4
 181 .IX Item "-C"
 182 Cancel an ongoing \s-1TPM\s0 command.
 183 .IP "\fB\-h data\fR" 4
 184 .IX Item "-h data"
 185 Reset and extend \s-1PCR 17\s0 with the hash of the given data. If data is the single
 186 character '\-', then all data are read from stdin.
