32.2.1 Register Descriptions
32.2.1.1
Offset 000h: GCAP_ID - General Capabilities and ID Register
General Behavioral Rules:
• Writes to this register must not be attempted by software.
• Software can read the various bytes in this register using 32-bit or 64-bit accesses.
• 32-bit accesses can be done to offset 00h or 04h, but not to offsets 01h, 02h, 03h,
05h, 06h, or 07h.
• 64-bit accesses can only be done to 00h.

Main Counter Tick Period: This read-only field indicates
COUNTER_
CLK_PER_CAP
the period at which the counter increments in
femptoseconds (10^-15 seconds). This returns
0429B17Fh when read indicating a period of 69841279 fs
(69.841279 ns).
VENDOR_ID_ Vendor ID Capability: These bits return 8086h when
CAP
read. This is a 16-bit value assigned to Intel.
Legacy Replacement Rout Capable:
LEG_RT_CAP This bit is always one when read, as the Legacy
Replacement Interrupt Rout is supported.
Reserved Reserved: This bit returns zero when read.
