c6317b8376 Correct vt(4) border calculations on font switch
If a vt(4) font does not exactly fit the screen dimensions, the console
window is offset so that it is centered.  A rectangle is drawn at the
top, left, right, and bottom of the screen, to erase any leftovers that
are outside of the new usable console area.

If the x offset or y offset is 0 then the left border or top border
respectively is not drawn.  The right and bottom borders may be one
pixel larger than necessary due to rounding, and are always drawn.

Prior to this change a 0 offset would result in a panic when calling
vt_drawrect with an x or y coordinate of -1.

	Improve the udp_dontroute test.  The bug that this test exercises is
	that ifa_ifwithnet() will return the wrong address, if multiple
	interfaces have addresses on the same subnet but with different
	fibs.  The previous version of the test only considered one possible
	failure mode: that ifa_ifwithnet_fib() might fail to find any

cb07f5b377 For old CPUs, map the 64 first MB of RAM as it used to be. Some ports
(XScale mainly) expects the memory located before the kernel to be mapped,

A better fix would probably be to rewrite the various bla_machdep.c to stop
using that RAM, but I'm not so inclined to do it, especially since I don't
have hardware for all of them.

Put the htonl(), htons(), ntohl() and ntohs() declarations under
__POSIX_VISIBLE >= 200112. POSIX.1-2001 and newer require these to be
exposed from <netinet/in.h> (as well as <arpa/inet.h>).

Note that it may be unnecessary to check __POSIX_VISIBLE >= 200112 because
older versions of POSIX and the C standard do not define this header.
However, other places in the same file already perform the check.

5b892e7363 Initialize r_flags the same way in all cases using a sanitized copy of
flags that has several bits cleared. The RF_WANTED and RF_FIRSTSHARE
bits are invalid in this context, and we want to defer setting RF_ACTIVE
in r_flags until later.  This should make rman_get_flags() return
the correct answer in all cases.

Add a KASSERT() to catch callers which incorrectly pass the RF_WANTED
or RF_FIRSTSHARE flags.

Do a strict equality check on the share type bits of flags.  In
particular, do an equality check on RF_PREFETCHABLE.  The previous
code would allow one type of mismatch of RF_PREFETCHABLE but disallow
the other type of mismatch.  Also, ignore the the RF_ALIGNMENT_MASK
bits since alignment validity should be handled by the amask check.
This field contains an integer value, but previous code did a strange
bitwise comparison on it.

Leave the original value of flags unmolested as a minor debug aid.

Change the start+amask overflow check to a KASSERT() since it is just
meant to catch a highly unlikely programming error in the caller.

0c12d5ed93 Fix DMA handling in radeon_dummy_page_init():
- Based on actual usage and on what Linux does, dummy_page.addr should
  contain the physical bus address of the dummy page rather than its
  virtual one. As a side-effect, correcting this bug fixes compilation
  with PAE support enabled by getting rid of an inappropriate cast.
- Also based on actual usage of dummy_page.addr, theoretically Radeon
  devices could do a maximum of 44-bit DMA. In reality, though, it is
  more likely that they only support 32-bit DMA, at least that is what
  radeon_gart_table_ram_alloc() sets up for, too. However, passing ~0
  to drm_pci_alloc() as maxaddr parameter translates to 64-bit DMA on
  amd64/64-bit machines. Thus, use BUS_SPACE_MAXSIZE_32BIT instead,
  which the existing 32-bit DMA limits within the drm2 code spelled as
  0xFFFFFFFF should also be changed to.

Add a new zfs property, "redundant_metadata" which can have values "all" or

to all, ZFS stores an extra copy of all metadata.  If a single on-disk block
is corrupt, at worst a single block of user data (which is recordsize bytes
long) can be lost.

Setting to "most" will cause us to only store 1 copy of level-1 indirect
blocks of user data files.  This can improve performance of random writes,
because less metadata has to be written.  In practice,  at worst about
100 blocks (of recordsize bytes each) of user data can be lost if a single
on-disk block is corrupt.

The exact behavior of which metadata blocks are stored redundantly may change
in future releases.

  feature bits that could allow a guest to trigger a GP# in the host with
  the current approach of allowing anything the host supports.
- Add proper checking of Intel MPX and AVX-512 XSAVE features in the
  xsetbv emulation and allow these features to be exposed to the guest if
  they are enabled in the host.
- Expose a subset of known-safe features from leaf 0 of the structured
  extended features to guests if they are supported on the host including
  RDFSBASE/RDGSBASE, BMI1/2, AVX2, AVX-512, HLE, ERMS, and RTM.  Aside
  from AVX-512, these features are all new instructions available for use

298d969c53 cxgbe(4): netmap support for Terminator 5 (T5) based 10G/40G cards.
Netmap gets its own hardware-assisted virtual interface and won't take
over or disrupt the "normal" interface in any way.  You can use both
simultaneously.

For kernels with DEV_NETMAP, cxgbe(4) carves out an ncxl<N> interface
(note the 'n' prefix) in the hardware to accompany each cxl<N>
interface.  These two ifnet's per port share the same wire but really
are separate interfaces in the hardware and software.  Each gets its own
L2 MAC addresses (unicast and multicast), MTU, checksum caps, etc.  You
should run netmap on the 'n' interfaces only, that's what they are for.

With this, pkt-gen is able to transmit > 45Mpps out of a single 40G port
of a T580 card.  2 port tx is at ~56Mpps total (28M + 28M) as of now.
Single port receive is at 33Mpps but this is very much a work in
progress.  I expect it to be closer to 40Mpps once done.  In any case
the current effort can already saturate multiple 10G ports of a T5 card
at the smallest legal packet size.  T4 gear is totally untested.

- Put "_LE_" into the register access macros to indicate little endian

- Avoid using the bounce buffer when not strictly needed. Try to move
data directly using bus-space functions first.
- Ensure we preserve the reserved bits in the power down mode
register. Else the hardware goes into a non-recoverable state.
- Always use 32-bit access when writing or reading registers or FIFOs,
because the hardware is 32-bit oriented and don't really understand 8-
and 16-bit access.
- Correct writes to the memory address register. There is no need to

- Correct interval for interrupt endpoints.
- Optimise 90ns internal memory buffer read delay.

8bde802a2b The users of RSS shouldn't be directly concerned about hash -> CPU ID
mappings.  Instead, they should be first mapping to an RSS bucket and
then querying the RSS bucket -> CPU ID mapping to figure out the target
CPU.

When (if?) RSS rebalancing is implemented or some other (non round-robin)
distribution of work from buckets to CPU IDs, various bits of code - both
userland and kernel - will need to know how this mapping works.

So, to support this:

* Add a new function rss_m2bucket() - this maps an mbuf to a given bucket.
  Anything which is currently doing hash -> CPU work may instead wish to
  do hash -> bucket, and then query the bucket->cpuid map for which
  CPU it belongs on.  Or, map it to a bucket, then re-pin that bucket ->
  CPU during a rebalance operation.

* For userland applications which wish to exploit affinity to RSS buckets,
  the bucket -> CPU ID mapping is now available via a sysctl.
  net.inet.rss.bucket_mapping lists the bucket to CPU ID mapping via
  a list of bucket:cpu pairs.

11d47032ee Eliminate one of the causes of spurious interrupts on armv6. The arm weak
memory ordering model allows writes to different devices to complete out
of order, leading to a situation where the write that clears an interrupt
source at a device can complete after a write that unmasks and EOIs the
interrupt at the interrupt controller, leading to a spurious re-interrupt.

This adds a generic barrier function specific to the needs of interrupt
controllers, and calls that function from the GIC and TI AINTC controllers.
There may still be other soc-specific controllers that need to make the call.

fa0f6e62c6 Initial import of character device in userspace support for FreeBSD.
The CUSE library is a wrapper for the devfs kernel functionality which
is exposed through /dev/cuse . In order to function the CUSE kernel
code must either be enabled in the kernel configuration file or loaded
separately as a module. Currently none of the committed items are
connected to the default builds, except for installing the needed
header files. The CUSE code will be connected to the default world and
kernel builds in a follow-up commit.

The CUSE module was written by Hans Petter Selasky, somewhat inspired
by similar functionality found in FUSE. The CUSE library can be used
for many purposes. Currently CUSE is used when running Linux kernel
drivers in user-space, which need to create a character device node to
communicate with its applications. CUSE has full support for almost
all devfs functionality found in the kernel:
 - kevents
 - read
 - write
 - ioctl
 - poll
 - open
 - close
 - mmap
 - private per file handle data

Since grub-bhyve does not initialize the 8259 this write to the mask register
takes a code path in which 'error' remains uninitialized (ready=0,icw_num=0).

96d67b46df Old PCIe implementations cannot allow a DMA transfer to cross a 4GB
boundary.  This was addressed several years ago by creating a parent
tag hierarchy for the root buses that set the boundary restriction
for appropriate buses and allowed child deviced to inherit it.
Somewhere along the way, this restriction was turned into a case for
marking the tag as a candidate for needing bounce buffers, instead
of just splitting the segment along the boundary line.  This flag
also causes all maps associated with this tag to be non-NULL, which
in turn causes bus_dmamap_sync() to take the slow path of function
pointer indirection to discover that there's no bouncing work to
do.  The end result is a lot of pages set aside in bounce pools
that will never be used, and a slow path for data buffers in nearly
every DMA-capable PCIe device.  For example, our workload at Netflix
was spending nearly 1% of all CPU time going through this slow path.

Fix this problem by being more selective about when to set the
COULD_BOUNCE flag.  Only set it when the boundary restriction
exists and the consumer cannot do more than a single DMA segment
at once.  This fixes the case of dynamic buffers (mbufs, bio's)
but doesn't address static buffers allocated from bus_dmamem_alloc().
That case will be addressed in the future.

For those interested, this was discovered thanks to Dtrace Flame
Graphs.

7032434e98 When exec_new_vmspace() decides that current vmspace cannot be reused
on execve(2), it calls vmspace_exec(), which frees the current
vmspace.  The thread executing an exec syscall gets new vmspace
assigned, and old vmspace is freed if only referenced by the current
process.  The free operation includes pmap_release(), which
de-constructs the paging structures used by hardware.

If the calling process is multithreaded, other threads are suspended
in the thread_suspend_check(), and need to be unsuspended and run to
be able to exit on successfull exec.  Now, since the old vmspace is
destroyed, paging structures are invalid, threads are resumed on the
non-existent pmaps (page tables), which leads to triple fault on x86.

To fix, postpone the free of old vmspace until the threads are resumed
and exited.  To avoid modifications to all image activators all of
which use exec_new_vmspace(), memoize the current (old) vmspace in
kern_execve(), and notify it about the need to call vmspace_free()
with a thread-private flag TDP_EXECVMSPC.

g_orphan_register and g_resize_provider_event. Both are called from the

So it is possible, that for some consumers an orphan method will be

b3e9732a76 Implement a PCI interrupt router to route PCI legacy INTx interrupts to
the legacy 8259A PICs.
- Implement an ICH-comptabile PCI interrupt router on the lpc device with
  8 steerable pins configured via config space access to byte-wide
  registers at 0x60-63 and 0x68-6b.
- For each configured PCI INTx interrupt, route it to both an I/O APIC
  pin and a PCI interrupt router pin.  When a PCI INTx interrupt is
  asserted, ensure that both pins are asserted.
- Provide an initial routing of PCI interrupt router (PIRQ) pins to
  8259A pins (ISA IRQs) and initialize the interrupt line config register
  for the corresponding PCI function with the ISA IRQ as this matches
  existing hardware.
- Add a global _PIC method for OSPM to select the desired interrupt routing
  configuration.
- Update the _PRT methods for PCI bridges to provide both APIC and legacy
  PRT tables and return the appropriate table based on the configured
  routing configuration.  Note that if the lpc device is not configured, no
  routing information is provided.
- When the lpc device is enabled, provide ACPI PCI link devices corresponding
  to each PIRQ pin.
- Add a VMM ioctl to adjust the trigger mode (edge vs level) for 8259A
  pins via the ELCR.
- Mark the power management SCI as level triggered.
- Don't hardcode the number of elements in Packages in the source for
  the DSDT.  iasl(8) will fill in the actual number of elements, and

Prior to this change accessing I/O ports [0xFFF8-0xFFFF] would trigger a

7ff2eaaad3 Give suitably-endowed ARMs a register similar to the x86 TSC register.
Here, "suitably endowed" means that the System Control Coprocessor
(#15) has Performance Monitoring Registers, including a CCNT (Cycle
Count) register.

The CCNT register is used in a way similar to the TSC register in
x86 processors by the get_cyclecount(9) function. The entropy-harvesting
thread is a heavy user of this function, and will benefit from not
having to call binuptime(9) instead.

One problem with the CCNT register is that it is 32-bit only, so
the upper 32-bits of the returned number are always 0. The entropy
harvester does not care, but in case any one else does, follow-up
work may include an interrup trap to increment an upper-32-bit
counter on CCNT overflow.

Another problem is that the CCNT register is not readable in user-mode
code; in can be made readable by userland, but then it is also
writable, and so is a good chunk of the PMU system. For that reason,
the CCNT is not enabled for user-mode access in this commit.

Like the x86, there is one CCNT per core, so they don't all run in
perfect sync.

afaa41f6b8 On a fork allow read-only wired pages to be copy-on-write shared between the
parent and child processes.  Previously, we copied these pages even though
they are read only.  However, the reason for copying them is historical and
no longer exists.  In recent times, vm_map_protect() has developed the
ability to copy pages when write access is added to wired copy-on-write
pages.  So, in this case, copy-on-write sharing of wired pages is not to be
feared.  It is not going to lead to copy-on-write faults on wired memory.

02bb9ba1cc Interrupts need to be disabled on entry to cpu_sleep() for ARM. Given
that and the need to be in a critical section when switching to idleclock
mode for event timers, use spinlock_enter()/exit() to achieve both needs.

The ARM WFI (wait for interrupt) instruction blocks until an interrupt is
asserted, and it will unblock even if interrupts are masked, and it will
unblock immediately if an interrupt is already pending.  It is necessary
to execute it with interrupts disabled, otherwise the interrupt that
should unblock it may occur and be serviced just prior to executing the
instruction.  At that point the system is inappropriately asleep until
the next timer tick or some other random interrupt happens.

In general, interrupts need to be disabled continuously from the time the
decision is made that there is no work to be done and sleeping is needed
until actually going to sleep, to avoid a race where handling a new
interrupt changes the basis for deciding there is no work to be done.

0c50edff52 Repair some races in IPI handling:
1. Make sure IPI mask is set before sending the IPI
2. Operate atomically on PS3 PIC outstanding interrupt list
3. Make sure IPIs are EOI'ed before, not after, processing. Without this,
   a second IPI could be sent partway through processing the first one,
   get erroneously acknowledge by the EOI to the first, and be lost. In
   particular in the case of smp_rendezvous(), this can be fatal.

In combination, this makes the PS3 boot SMP again. It probably also fixes
some latent bugs elsewhere.

857ce8a246 accept(),accept4(): Don't set *addrlen = 0 on [ECONNABORTED].
If the underlying protocol reported an error (e.g. because a connection was
closed while waiting in the queue), this error was also indicated by
returning a zero-length address. For all other kinds of errors (e.g.
[EAGAIN], [ENFILE], [EMFILE]), *addrlen is unmodified and there are
successful cases where a zero-length address is returned (e.g. a connection
from an unbound Unix-domain socket), so this error indication is not
reliable.

As reported in Austin Group bug #836, modifying *addrlen on error may cause
subtle bugs if applications retry the call without resetting *addrlen.

dd006a1b14 With the new-and-improved vm_fault_copy_entry() (r265843), we can always
avoid soft page faults when adding write access to user wired entries in
vm_map_protect().  Previously, we only avoided the soft page fault when
the underlying pages were copy-on-write.  In other words, we avoided the
pages faults that might sleep on page allocation, but not the trivial
page faults to update the physical map.

Prior to this change, if a system booted with Intel Turbo Boost enabled,
the dev.cpu.0.freq sysctl is nonfunctional, since the ACPI-reported
frequency for Turbo Boost states does not match the actual clock frequency
(and thus no levels are within 25 MHz of the observed frequency) and the
current performance level is read before a new level is set.

b07d0cbce3 Add cpu_l2cache_drain_writebuf(), use it to implement generic_bs_barrier().
On modern ARM SoCs the L2 cache controller sits between the CPU and the
AXI bus, and most on-chip memory-mapped devices are on the AXI bus.  We
map the device registers using the 'Device' memory attribute, which means
the memory is not cached, but writes to it are buffered.  Ensuring that a
write has made it all the way to a device may require that the L2
controller take some action.

There is currently only one implementation of the new function, for the
PL310 cache controller.  It invokes a function that the controller
manual calls "cache sync" but it actually has nothing to do with cache at
all, it triggers a drain of all pending store buffer writes and it blocks
until they complete.

The sheeva and xscale L2 controllers (which predate the concept of Device
memory) don't seem to have a corresponding function.  It appears that the
standard armv5 drain_writebuf function includes draining all the way
through the L2 controller.
