No. Looks good to me.

Title:
HPET supports only one IRQ
Status in QEMU:
Incomplete
Bug description:
The emulated HPET only supports triggering IRQ 2. Since MSIs are by
default disabled, this severely limits the usefulness of the HPET as
only one timer block can effectively be used (otherwise they would
share IRQ 2). Ideally, the HPET should support as much timer blocks as
CPUs and each timer block can be driven by a different IRQ.
TIMER: HPET at fed00000 -> 0xbf500000.
TIMER: HPET vendor 8086 revision 01: LEGACY 64BIT
TIMER: HPET: cap 8086a201 config 0 period 10000000
TIMER: HPET Timer[0]: config 30 int 4
TIMER: HPET Timer[1]: config 30 int 4
TIMER: HPET Timer[2]: config 30 int 4
