GETCAPABILITY(1)

💖 NAME 💖

getcapability — bestie, it Runs TPM2_GetCapability. That's it, that's the whole job description. 👑

This is the GETCAPABILITY(1) page from the User Commands manual, and we're gonna get through it together, okay? 🫶

---

✨ DESCRIPTION ✨

Okay so first thing first, the page just... opens with this:

--version-string=v1045 is not a valid option

Not me getting yelled at by a manpage before it even says hi 😭 But fr fr, that line is in there, so we're keeping it. No cap.

🎀 getcapability 🎀

Runs TPM2_GetCapability. That's the mission. Main character energy, zero filler.

the flags, babe 💅

• -cap capability — the capability you're asking about
• -pr property — defaults to 0
• -pc propertyCount — defaults to 64
• -se[0-2] — session handle / attributes, and the default is PWAP
  • 01 continue
  • 80 command audit

-cap values 🦋

Pick your fighter, these are the exact names and numbers:

• TPM_CAP_ALGS — 0
• TPM_CAP_HANDLES — 1
• TPM_CAP_COMMANDS — 2
• TPM_CAP_PP_COMMANDS — 3
• TPM_CAP_AUDIT_COMMANDS — 4
• TPM_CAP_PCRS — 5
• TPM_CAP_TPM_PROPERTIES — 6
• TPM_CAP_PCR_PROPERTIES — 7
• TPM_CAP_ECC_CURVES — 8

🌸 and then it does it AGAIN 🌸

Not the manpage hitting copy-paste and calling it a day 💀 Bestie, I'm not editing the lore, so here's the whole thing a second time, exactly as it appears:

--version is not a valid option

🧚 getcapability 🧚

Runs TPM2_GetCapability.

• -cap capability
• -pr property — defaults to 0
• -pc propertyCount — defaults to 64
• -se[0-2] — session handle / attributes, default PWAP
  • 01 continue
  • 80 command audit

-cap values, the sequel ✨

• TPM_CAP_ALGS — 0
• TPM_CAP_HANDLES — 1
• TPM_CAP_COMMANDS — 2
• TPM_CAP_PP_COMMANDS — 3
• TPM_CAP_AUDIT_COMMANDS — 4
• TPM_CAP_PCRS — 5
• TPM_CAP_TPM_PROPERTIES — 6
• TPM_CAP_PCR_PROPERTIES — 7
• TPM_CAP_ECC_CURVES — 8

Okay real talk: yes, the description literally repeats itself word for word, and the second round leads with a different error line (--version is not a valid option). I'm not fixing it, I'm not merging it, I'm not guessing what it means. I'm just holding it up to the light like the icon it is. 🫶
