illumos gate

SMBIOS type 21 indicates built-in pointer devices. I was decoding a table from another system and noticed that we couldn't decode this. Since it was simple enough, I decided to do so. Here's an example of what that looks like:

$ LD_PRELOAD_32=../../lib/libsmbios/i386/libsmbios.so.1 ./smbios -t 21 ~/laptop.smbios
ID    SIZE TYPE
52    7    SMB_TYPE_POINTDEV (type 21) (built-in pointing device)

  Type: 5 (Track Point)
  Interface: 4 (PS/2)
  Buttons: 3

ID    SIZE TYPE
53    7    SMB_TYPE_POINTDEV (type 21) (built-in pointing device)

  Type: 7 (Touch Pad)
  Interface: 4 (PS/2)
  Buttons: 2

I also ran the current SMBIOS test suite (on top of 12133) and it passed:

TEST PASSED: slot tests
TEST PASSED: bad library version

TEST PASSED: memory device 3.2 / 3.3
