49ed68bbf3 Add "legacy route" support to HPET driver. When enabled, this mode makes
HPET to steal IRQ0 from i8254 and IRQ8 from RTC timers. It can be suitable
for HPETs without FSB interrupts support, as it gives them two unshared
IRQs. It allows them to provide one per-CPU event timer on dual-CPU system,
that should be suitable for further tickless kernels.

To enable it, such lines may be added to /boot/loader.conf:
hint.atrtc.0.clock=0
hint.attimer.0.clock=0
hint.hpet.0.legacy_route=1

875b8844be Implement new event timers infrastructure. It provides unified APIs for
writing event timer drivers, for choosing best possible drivers by machine
independent code and for operating them to supply kernel with hardclock(),
statclock() and profclock() events in unified fashion on various hardware.

Infrastructure provides support for both per-CPU (independent for every CPU
core) and global timers in periodic and one-shot modes. MI management code
at this moment uses only periodic mode, but one-shot mode use planned for
later, as part of tickless kernel project.

For this moment infrastructure used on i386 and amd64 architectures. Other
archs are welcome to follow, while their current operation should not be
affected.

This patch updates existing drivers (i8254, RTC and LAPIC) for the new
order, and adds event timers support into the HPET driver. These drivers
have different capabilities:
 LAPIC - per-CPU timer, supports periodic and one-shot operation, may
freeze in C3 state, calibrated on first use, so may be not exactly precise.
 HPET - depending on hardware can work as per-CPU or global, supports
periodic and one-shot operation, usually provides several event timers.
 i8254 - global, limited to periodic mode, because same hardware used also
as time counter.
 RTC - global, supports only periodic mode, set of frequencies in Hz
limited by powers of 2.

Depending on hardware capabilities, drivers preferred in following orders,
either LAPIC, HPETs, i8254, RTC or HPETs, LAPIC, i8254, RTC.
User may explicitly specify wanted timers via loader tunables or sysctls:
kern.eventtimer.timer1 and kern.eventtimer.timer2.
If requested driver is unavailable or unoperational, system will try to
replace it. If no more timers available or "NONE" specified for second,
system will operate using only one timer, multiplying it's frequency by few
times and uing respective dividers to honor hz, stathz and profhz values,
set during initial setup.

7150e67191 While we indeed can't precisely measure time spent in C1, we can consider
measured interval as upper bound. It should be more precise then just
assuming hz/2. For idle CPU it should be quite precise, for busy - not
worse then before.

42040ff081 When updating individual CPU's lowest Cx state to use, never set it to a
state lower than the lowest one supported by the current CPU.  This closes
some races with changes to the hw.acpi.cpu_cx_lowest sysctl while Cx
states for individual CPUs were changing (e.g. unplugging the AC adapter
of a laptop) that could result in panics.

a9bdb5d3ad sound/pcm: use non-const string as a value with SYSCTL_STRING
Although the sysctls are marked with CTLFLAG_RD and the values will stay
immutable, current sysctl implementation stores value pointer in
void* type, which means that const qualifier is discarded anyway
and some newer compilers complaint about that.
We can't use de-const trick in sysctl implementation, because in that
case we could miss an opposite situation where a const value is used
with CTLFLAG_RW sysctl.

db5ef4fc77 Convert Marvell ARM platforms to FDT convention.
The following systems are involved:

  - DB-88F5182
  - DB-88F5281
  - DB-88F6281
  - DB-78100
  - SheevaPlug

This overhaul covers the following major changes:

  - All integrated peripherals drivers for Marvell ARM SoC, which are
    currently in the FreeBSD source tree are reworked and adjusted so they
    derive config data out of the device tree blob (instead of hard coded /
    tabelarized values).

  - Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
    good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

27d1c65e8e cxgb(4): add knob to get packet timestamps from the hardware.
The T3 ASIC can provide an incoming packet's timestamp instead of its RSS hash.
The timestamp is just a counter running off the card's clock.  With a 175MHz
clock an increment represents ~5.7ns and the 32 bit value wraps around in ~25s.

# sysctl -d dev.cxgbc.0.pkt_timestamp
dev.cxgbc.0.pkt_timestamp: provide packet timestamp instead of connection hash

# sysctl -d dev.cxgbc.0.core_clock
dev.cxgbc.0.core_clock: core clock frequency (in KHz)
# sysctl dev.cxgbc.0.core_clock

ddaa454e6a Apply driver update from LSI. Many thanks to LSI for continuing to
support FreeBSD.

  1) Timeout ioctl command timeouts.
       Do not reset the controller if ioctl command completed
       successfully.
  2) Remove G66_WORKAROUND code (this bug never shipped).
  3) Remove unnecessary interrupt lock (intr_lock).
  4) Timeout firmware handshake for PChip reset (don't wait forever).
  5) Handle interrupts inline.
  6) Unmask command interrupt ONLY when adding a command to the pending
     queue.
  7) Mask command interrupt ONLY after removing the last command from
     the pending queue.
  8) Remove TW_OSLI_DEFERRED_INTR_USED code.
  9) Replace controller "state" with separate data fields to avoid races:

       TW_CLI_CTLR_STATE_ACTIVE                     ctlr->active
       TW_CLI_CTLR_STATE_INTR_ENABLED               ctlr->interrupts_enabled
       TW_CLI_CTLR_STATE_INTERNAL_REQ_BUSY          ctlr->internal_req_busy
       TW_CLI_CTLR_STATE_GET_MORE_AENS              ctlr->get_more_aens
       TW_CLI_CTLR_STATE_RESET_IN_PROGRESS          ctlr->reset_in_progress
       TW_CLI_CTLR_STATE_RESET_PHASE1_IN_PROGRESS   ctlr->reset_phase1_in_progress

 10) Fix "req" leak in twa_action() when simq is frozen and req is NOT
     null.
 11) Replace softc "state" with separate data fields to avoid races:
       TW_OSLI_CTLR_STATE_OPEN                      sc->open
       TW_OSLI_CTLR_STATE_SIMQ_FROZEN               sc->simq_frozen
 12) Fix reference to TW_OSLI_REQ_FLAGS_IN_PROGRESS in
     tw_osl_complete_passthru()
 13) Use correct CAM status values.
       Change CAM_REQ_CMP_ERR to CAM_REQ_INVALID.
       Remove use of CAM_RELEASE_SIMQ for physical data addresses.
 14) Do not freeze/ release the simq with non I/O commands.
       When it is appropriate to temporarily freeze the simq with an I/O
       command use:
         xpt_freeze_simq(sim, 1);
         ccb->ccb_h.status |= CAM_RELEASE_SIMQ;
       otherwise use:
         xpt_freeze_simq(sim, 1);
         xpt_release_simq(sim, 1);
