3800322fe2 Implement 'show mount' command in DDB. Without argument, it prints short
info about all currently mounted file systems. When an address is given
as an argument, prints detailed info about the given mount point.

b7ee09f7b0 Remove the MD isa_irq_pending() and the underlying PCI-specific
infrastructure. Its only consumer ever was sio(4) and thus was
unused on sparc64 since removing the last traces of sio(4) in
sparc64 configuration files in favor for uart(4) over three
years ago. If similar functionality is required again it should
be brought back as an MD intr_pending() which works for all
busses by using for example interrupt controller hooks.

20e8415eb4 This delta has a few important items:
PR 122839 is fixed in both em and in igb

Second, the issue on building modules since the static kernel
build changes is now resolved. I was not able to get the fancier
directory hierarchy working, but this works, both em and igb
build as modules now.

Third, there is now support in em for two new NICs, Hartwell
(or 82574) is a low cost PCIE dual port adapter that has MSIX,
for this release it uses 3 vectors only, RX, TX, and LINK. In
the next release I will add a second TX and RX queue. Also, there
is support here for ICH10, the followon to ICH9. Both of these are
early releases, general availability will follow soon.

Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support,
I have implemented this in a provisional way so that early adopters
may try and comment on the functionality. The IOCTL structure may
change. This feature is off by default, you need to edit the Makefile
and add the EM_TIMESYNC define to get the code.

Enjoy all!!

6c47aaae12 - Add an integer argument to idle to indicate how likely we are to wake
from idle over the next tick.
 - Add a new MD routine, cpu_wake_idle() to wakeup idle threads who are
   suspended in cpu specific states.  This function can fail and cause the
   scheduler to fall back to another mechanism (ipi).
 - Implement support for mwait in cpu_idle() on i386/amd64 machines that
   support it.  mwait is a higher performance way to synchronize cpus
   as compared to hlt & ipis.
 - Allow selecting the idle routine by name via sysctl machdep.idle.  This
   replaces machdep.cpu_idle_hlt.  Only idle routines supported by the
   current machine are permitted.

da28723ecd o Disable HMEDEBUG by default.
o Add CTASSERTs ensuring that HME_NRXDESC and HME_NTXDESC are set to
  legal values.
o Use appropriate maxsize, nsegments and maxsegsize parameters when
  creating DMA tags and correct some comments related to them.
o The FreeBSD bus_dmamap_sync(9) supports ored together flags for quite
  some time now so collapse calls accordingly.
o Add missing BUS_DMASYNC_PREREAD when syncing the control DMA maps in
  hme_rint() and hme_start_locked().
o Keep state of the link state and use it to enable or disable the MAC
  in hme_mii_statchg() accordingly as well as to return early from
  hme_start_locked() in case the link is down.
o Introduce a sc_flags and use it to replace individual members like
  sc_pci.
o Add bus_barrier(9) calls to hme_mac_bitflip(), hme_mii_readreg(),
  hme_mii_writereg() and hme_stop() to ensure the respective bit
  has been written before we starting polling on it and for the right
  bits to change.
o Rather just returning in case hme_mac_bitflip() fails and leaving us
  in an undefined state report the problem and move on; chances are
  the requested configuration will become active shortly after.
o Don't call hme_start_locked() in hme_init_locked() unconditionally
  but only after calls to hme_init_locked() when it's appropriate, i.e.
  in hme_watchdog().
o Add a KASSERT which asserts nsegs is valid also to hme_load_txmbuf().
o In hme_load_txmbuf():
  - use a maximum of the newly introduced HME_NTXSEGS segments instead
    of the incorrect HME_NTXQ, which reflects the maximum TX queue
    length, for loading the mbufs and put the DMA segments back onto
    the stack instead of the softc as 16 should be ok there.
  - use the common errno(2) return values instead of homegrown ones,
  - given that hme_load_txmbuf() is allowed to fail resulting in a
    packet drop for quite some time now implement the functionality of
    hme_txcksum() by means of m_pullup(9), which de-obfuscates the code
    and allows to always retrieve the correct length of the IP header, [1]
  - also add a KASSERT which asserts nsegs is valid,
  - take advantage of m_collapse(9) instead of m_defrag(9) for
    performance reasons.
o Don't bother to check whether the interface is running or whether its
  queue is empty before calling hme_start_locked() in hme_tint(), the
  former will check these anyway.
o In hme_intr() call hme_rint() before hme_tint() as gem_tint() may
  take quite a while to return when it calls hme_start_locked().
o Get rid of sc_debug and just check if_flags for IFF_DEBUG directly.
o Add a shadow sc_ifflags so we don't reset the chip when unnecessary.
o Handle IFF_ALLMULTI correctly. [2]
o Use PCIR_BAR instead of a homegrown macro.
o Replace sc_enaddr[6] with sc_enaddr[ETHER_ADDR_LEN].
o Use the maximum of 256 TX descriptors for better performance as using
  all of them has no additional static cost rather than using just half
  of them.

82897554f5 - Use bus_{read,write}_*(9) instead of bus_space_{read,write}_*(9)
in order to get rid of bus space handle and tag in struct sym_hcb.
- Remove unused members related to bus addresses in struct sym_hcb.
- sym(4) takes care of allocating an instance of struct sym_hcb
  itself so don't let newbus allocate it as an unused softc also.
- Add basic MPSAFE locking. This includes changing the sym(4) CCBs
  to be allocated up-front instead of on demand as needed. Besides
  making these allocations more likely to succeed, this also solves
  the problem of calling bus_dmamap_create(9) with the SIM mutex
  held.

5db670520f Implement the G_PART_DUMPCONF method for all 6 schemes. Also call
the method for the (indent == NULL) case (i.e. the kern.geom.conftxt
sysctl). The purpose is to extend the conftxt output with scheme-
specific fields which can be used by libdisk. In particular, have
the schemes dump the xs and xt fields, which contain the backward
compatible values for class type and partition type. This allows
libdisk to work with the legacy slicers as well as with gpart and
helps/promotes migration.

526bd70425 o Rename ic_eoi to ic_clear to emphasize the functions it points
don't send and EOI which works like on amd64/i386 and blocks all
  interrupts on the relevant interrupt controller.
o Replace the post_filter and post_inthread hooks registered when
  creating the interrupt events with just ic_clear as on sparc64 we
  don't need to do any disable->EOI->enable dance to unblock all but
  the relevant interrupt while running the filter or handler; just
  not clearing the interrupt already has the same effect.
o Merge from amd64/i386:
  - Split the intr_table_lock into an sx lock used for most things,
    and a spin lock to protect intrcnt_index.
  - Add support for binding interrupts to CPUs, including for the
    bus_bind_intr(9) interface, a assign_cpu hook and initially
    shuffling interrupts arround in a round-robin fashion.

9b4a8ab7ba Now that all platforms use genclock, shuffle things around slightly
for better structure.

Much of this is related to <sys/clock.h>, which should really have
been called <sys/calendar.h>, but unless and until we need the name,
the repocopy can wait.

In general the kernel does not know about minutes, hours, days,
timezones, daylight savings time, leap-years and such.  All that
is theoretically a matter for userland only.

Parts of kernel code does however care: badly designed filesystems
store timestamps in local time and RTC chips almost universally
track time in a YY-MM-DD HH:MM:SS format, and sometimes in local
timezone instead of UTC.  For this we have <sys/clock.h>

<sys/time.h> on the other hand, deals with time_t, timeval, timespec
and so on.  These know only seconds and fractions thereof.

Move inittodr() and resettodr() prototypes to <sys/time.h>.
Retain the names as it is one of the few surviving PDP/VAX references.

Move startrtclock() to <machine/clock.h> on relevant platforms, it
is a MD call between machdep.c/clock.c.  Remove references to it
elsewhere.

Remove a lot of unnecessary <sys/clock.h> includes.

Move the machdep.disable_rtc_set sysctl to subr_rtc.c where it belongs.
XXX: should be kern.disable_rtc_set really, it's not MD.
