Hi folks,


I am building my TPM 2.0 driver as Kernel modules (tpm.ko, tpm_tis_core.ko = and tpm_tis.ko).

 

I noticed that while my /sys/ke= rnel/security directory is created and mounted to securityFS, it is empty.

 

Looking at tpm_bios_log_setup()= in tpm1_event.log, I see that this is being done during chip registration:=

 

if (chip->flags & TPM_CH= IP_FLAG_TPM2)

     &= nbsp;  chip->bin_log_seqops.seqops =3D

     &= nbsp;      &tpm2_binary_b_measurements_seqops;=

    else

     &= nbsp;  chip->bin_log_seqops.seqops =3D

     &= nbsp;      &tpm_binary_b_measurements_seqops;<= o:p>

 

 

    chip->bio= s_dir[cnt] =3D

     &= nbsp;  securityfs_create_file("binary_bios_measurements",

     &= nbsp;           &nbs= p; 0440, chip->bios_dir[0],

     &= nbsp;           &nbs= p; (void *)&chip->bin_log_seqops,

     &= nbsp;           &nbs= p; &tpm_bios_measurements_ops);

    if (IS_ERR(c= hip->bios_dir[cnt]))

     &= nbsp;  goto err;

 

 

My TPM modules are loaded prope= rly and I can interact with TPM using userspace TSS2 applications:

 

$ sudo lsmod | grep tpm

Password:

tpm_crb    =              64= 58  0

tpm_tis    =              59= 50  0

tpm_tis_core   &= nbsp;       10054  1 tpm_tis<= /span>

tpm    &nbs= p;            &= nbsp;  48093  3 tpm_crb,tpm_tis,tpm_tis_core

Thoughts?

Hi folks,<= /span>


I am building my TPM 2.0 driver as Kernel modules (tpm.ko, tpm_tis_core.ko and tpm_tis.ko).

=A0=

I noticed that while = my /sys/kernel/security directory is created and mounted to securityFS, it is empty.

Looking at tpm_bios_log_setup() in tpm1_event.log, I see that this is being done during chip registration:

TPM 2.0 binary_bios_measurements event log file support is currently not available for ACPI based platform. It is only for device tree based platform. And I think you are using ACPI.

Thank you Nayna for ge= tting back to me, yes I am using ACPI so that would explain it.<= /span>

 

Which brings me to my = last issue, I am not seeing the PCRS file in either of these locations:

/sys/devices/pnp0/<pnp#>/= pcrs

/sys/devices/platform/tpm_tis/p= crs

 

I am loading TPM as ke= rnel modules so is this behavior not supported when TPM is not built-in, or= are these files specific to TPM 1.2?

 

 

Thanks,
Kam

Hi folks,


I am building my TPM 2.0 driver as Kernel modules (tpm.ko, tpm_tis_core.ko = and tpm_tis.ko).

 

I noticed that while my /sys/ke= rnel/security directory is created and mounted to securityFS, it is empty.

 

Looking at tpm_bios_log_setup()= in tpm1_event.log, I see that this is being done during chip registration:=

TPM 2.0 binary_bios_measurements eve= nt log file support is currently not available for ACPI based platform. It = is only for device tree based platform. And I think you are using ACPI.

Thanks & Regards,

if (chip->flags & TPM_CH= IP_FLAG_TPM2)

     &= nbsp;  chip->bin_log_seqops.seqops =3D

    if (IS_ERR(c= hip->bios_dir[cnt]))

     &= nbsp;  goto err;

 

 

My TPM modules are loaded prope= rly and I can interact with TPM using userspace TSS2 applications:

 

$ sudo lsmod | grep tpm<= o:p>

How and when would this file be= created? For that matter I don’t even have a /sys/devices/pnp0/<p= np#>/pcrs file present

Thoughts?
