e55b30b469 Fix syscons on amd64. The SC_PIXEL_MODE commit from May 29th added a new
function pointer to the vga render dispatch table and initialized it with
vga_nop.  The problem is that vga_nop() is a varargs function, and the
table declares a non-varargs function pointer.  On amd64 (and I think ppc),
mixing varargs and non-varargs function pointers is fatal.

Change vga_nop() and gfb_nop() from varargs to non-varargs do-nothing
functions.  This stops the stack corruption that only happened on amd64.

dbb3ec5ce3 - Remove vnode lock asserts at the end of vfs syscalls. These asserts were
used to ensure that we weren't exiting the syscall with a lock still
   held.  This wasn't safe, however, because we'd already executed a vput()
   and on a loaded system the vnode may have been free'd by the time we
   assert.  This functionality is also handled by the td_locks assert in
   userret, which doesn't tell you what the syscall was, but will at least
   panic before you deadlock.

It can be used to panic the kernel by giving too big value.
Fix it by moving allocation and size verification into kern_getfsstat().

a534973af4 The new contigmalloc(9) has a bad degenerate case where there were
many regions checked again and again despite knowing the pages
contained were not usable and only satisfied the alignment constraints
This case was compounded, especially for large allocations, by the
practice of looping from the top of memory so as to keep out of the
important low-memory regions.  While the old contigmalloc(9) has the
same problem, it is not as noticeable due to looping from the low
memory to high.

This degenerate case is fixed, as well as reversing the sense of the
rest of the loops within it, to provide a tremendous speed increase.
This makes the best case O(n * VM overhead) much more likely than the
worst case O(4 * VM overhead).  For comparison, the worst case for old
contigmalloc would be O(5 * VM overhead) in addition to its strategy
of turning used memory into free being highly pessimal.

Also, fix a bug that in practice most likely couldn't have been triggered,
int the new contigmalloc(9): it walked backwards from the end of memory
without accounting for how many pages it needed.  Potentially, nonexistant
pages could have been mapped.  This hasn't occurred because the kernel
generally requests as its first contigmalloc(9) a single page.

cc3149b1ea Fix a serious deadlock with the NFS client. Given a large enough
atomic write request, it can fill the buffer cache with the entirety
of that write in order to handle retries.  However, it never drops
the vnode lock, or else it wouldn't be atomic, so it ends up waiting
indefinitely for more buf memory that cannot be gotten as it has it
all, and it waits in an uncancellable state.

To fix this, hibufspace is exported and scaled to a reasonable
fraction.  This is used as the limit of how much of an atomic write
request by the NFS client will be handled asynchronously.  If the
request is larger than this, it will be turned into a synchronous
request which won't deadlock the system.  It's possible this value is
far off from what is required by some, so it shall be tunable as soon
as mount_nfs(8) learns of the new field.

The slowdown between an asynchronous and a synchronous write on NFS
appears to be on the order of 2x-4x.

a3d97e12a0 Turn on atkbdc(4), atkbd(4), creator(4), machfb(4), syscons(4), ohci(4),
psm(4), ukbd(4), ums(4) and usb(4) on by default. Modulo some nits with
the most annoying one probably being USB keyboards no longer working at
the OFW boot prompt after halting FreeBSD these drivers work fine on
sparc64 including X and there's nothing left that I'd consider a show-
stopper. I.e. graphical consoles on sun4u machines should either work
out of the box or by plugging in a card that is supported by either
creator(4) or machfb(4). The exception obviously are SBus-only machines
without UPA slots like some Ultra 1 (but which also still lack support
in other areas) and certain Exx0 (but which probably are mainly used
with serial consoles anyway). I'll try to add a cgsix(4) for these later
as Sun CG6 cards are probably the most common SBus framebuffer cards in
sun4u machines. I however don't see much sense in adding drivers for the
dozen of SBus framebuffers that were destined for sparc v8 machines.
The rest of the USB drivers aren't enabled as I'm only aware of ukbd(4)
and ums(4) as well as ohci(4) working with the on-board ALI M5237 and
Sun PCIO-2 controllers. Aue(4) definitely doesn't work on sparc64, yet.

Thanks to:
- Jake for the initial work on syscons(4) on sparc64 and creator(4).
- Marcel for uart(4) and especially for its support for the SCCs which
  are only used on sparc64 so far. In various regards it wouldn't have

520b635320 - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
  atkbdc(4) and its children were moved to the new location in preparation
  for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
  order to not further scatter them over the whole tree which would have
  been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
  reason for the repo-copies was that some of the sources were misfiled,
  e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
  atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
  Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
  ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
  but are shareable between different atkbdc(4) bus front-ends into
  atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
  bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
  respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
  atkbdc(4). PS/2 controllers and input devices are used on a couple of
  Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
  the board it's either the only on-board mean to connect a keyboard and
  mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
  without isa(4) (e.g. for EBus-only machines). This ISA-specific part
  isn't separated into its own source file, yet, as it requires more work
  than was feasible for 6.0 in order to do it in a clean way. Actually
  philip@ is working on a rewrite of psm(4) so a more comprehensive
  clean-up and separation of hardware dependent and independent parts is
  expected to happen after 6.0.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

do the subsequent ip_output() in IPFW.  In ipfw_tick(), the keep-alive
packets must be generated from the data that resides under the
stateful lock, but they must not be sent at that time, as this would
cause a lock order reversal with the normal ordering (interface's
lock, then locks belonging to the pfil hooks).

In practice, this caused deadlocks when using IPFW and if_bridge(4)

hack MSS of packets outgoing via interface with small MTU, to workaround
path MTU discovery problems.

Written by Alexey Popov, with some cleanups from me. There are also plans
to improve mpd port, so that it uses this node, instead of doing MSS
hacking in userland, when 'enable tcpmssfix' option is on.

1c245ae7d1 Introduce a procedure, pmap_page_init(), that initializes the
vm_page's machine-dependent fields.  Use this function in
vm_pageq_add_new_page() so that the vm_page's machine-dependent and
machine-independent fields are initialized at the same time.

Remove code from pmap_init() for initializing the vm_page's
machine-dependent fields.

Remove stale comments from pmap_init().

Eliminate the Boolean variable pmap_initialized from the alpha, amd64,
i386, and ia64 pmap implementations.  Its use is no longer required
because of the above changes and earlier changes that result in physical
memory that is being mapped at initialization time being mapped without
pv entries.

a4bfd6388f Import a mostly rewritten and extended version of acpi_ibm:
- Restructured for easier extensibility and maintainability
- To be more uniform with the other ACPI extras drivers and to better reflect
  their actual meaning, some sysctls were moved:
    o brightness -> lcd_brightness
    o keylight   -> thinklight
    o enable     -> events
    o misckey    -> hotkey
    o avail_mask -> availmask
    o key_mask   -> eventmask
- New "initialmask" sysctl, which holds the initial eventmask
- The "wlan" sysctl is now read-only, since writing to it didn't have
  any effect
- The "version" sysctl was removed, since it seems to be the same (0x100)
  on all models I have seen
- Support for more hotkeys by the "hotkey" sysctl
- Improved support of ACPI events. Disabled by default, since it unexpectedly
  changes the behaviour of some keys. (on my T41p there are now 24 different
  keypress events that get reported)
- write support for: volume, mute, lcd_brightness and thinklight
- led(4) interface for the thinklight [1]
- New sysctls "fan" and "fan_speed" to support reading of fan status and speed
- New sysctl "thermal" to support reading of up to 8 thermal sensors

causes more variables to move around on i386, and is much less disruptive
on other platforms.  This has been tested on i386, ppc, and sparc, and has
at least been compiled on everything but arm.

9e879a5ee0 - Under heavy IO load the buf daemon can run for many hundereds of
milliseconds due to what is essentially n^2 algorithmic complexity.  This
   change makes the algorithm N*2 instead.  This heavy processing manifested
   itself as skipping in audio and video playback due to the long scheduling
   latencies and contention on giant by pcm.
 - flushbufqueues() is now responsible for flushing multiple buffers
   rather than one at a time.  This allows us to save our progress in the
   list by using a sentinal.  We must do the numdirtywakeup() and
   waitrunningbufspace() here now rather than in buf_daemon().
 - Also add a uio_yield() after we have processed the list once for bufs
   without deps and again for bufs with deps.  This is to release Giant
   and allow any other giant locked code to proceed.

3a61f787fb Replace the band-aid for allowing to call sunkbd_configure() multiple
times which was added in the last revision with what should be a proper
solution as long as keyboards that were pluggged in after the kernel
has fully booted aren't supported. I.e. when sunkbd_configure() is
called for the high-level console probe make sure that the keyboard is
both successfully configured (i.e. also probed) and attached. The band-
aid left the possibility to attach the keyboard device to the high-level
console without attaching the keyboard device itself when the keyboard
is plugged in after uart(4) attached but before syscons(4) does.

852962d3c5 On AXi and AXmp boards the NS16550 (used to connect keyboard and mouse)
share their IRQ lines with the i8042. Any IRQ activity (typically during
attach) on the NS16550 used to connect the keyboard when actually the
PS/2 keyboard is selected in OFW causes interaction with the OBP i8042
driver resulting in a hang (and vice versa). As RS232 keyboards and mice
obviously aren't meant to be used in parallel with PS/2 ones on these
boards don't attach to these NS16550 in case the RS232 keyboard isn't
selected in order to prevent such hangs.

ecf4269527 Change the semantics of uart_cpu_getdev_keyboard() to only match SCCs/
UARTs used to connect keyboards and not also PS/2 keyboards and only
return their package handle in case the keyboard is the preferred one
according to the OFW but otherwise still regardless of whether the
keyboard is used for stdin or not. This is simply achieved by looking
at the 'keyboard' alias and returning the corresponding package handle
in case it refers to a SCC/UART. This is change is done in order to
give the keyboard which the OFW or the user selected in OFW on boards
that support additional types of keyboards besides the RS232 ones also
preference in FreeBSD. It will be also used to determine on Sun AXi and
Sun AXmp boards whether a PS/2 or a RS232 is to be used as these are
sort of mutual exclusive there (see upcoming commit to uart_bus_ebus.c).
Note that Tatung AXi boards have the same issue but the former code
happened to already give the PS/2 keyboard preference by not identifying
the respective UART as keyboard system device there because the PS/2
keyboard node precedes the keyboard UART one in the OFW device tree of
these boards (which isn't the case for the Sun AXi).

df4b30bee2 - In creator_configure() when probed for the high-level console return
the number of registered adapters instead of determining again whether
  stdout is a supported card (and which might have failed to attach and
  register).
- Drop creator_set_mode() and move the relevant parts to creator_fill_rect()
  and creator_putc() respectively. This is a bit cleaner than having to
  make sure that creator_set_mode() was called before creator_fill_rect()
  or creator_putc() are used and matches better what Xorg does.
- Fix a bug in the handling of the FBIOSCURSOR IOCTL; the code was meant
  to return ENODEV for all invocations expect when used to disable the

- In case the adapter is the OFW stdout move its OFW cursor to the start
  of the last line on halt so OFW output doesn't get intermixed with what
  FreeBSD left on the screen. With hindsight this is what the faking of a
  hardware cursor which was removed in the last revision really was about,
  i.e. to keep the OFW updated about the current cursor position. The new
  approach however is simpler while producing the same result and doesn't
  cause the first letter of the OFW output to be turned into a blank and
  a newline.
- Add variable names to the prototypes of creator_cursor_*() which were
  added in the last revision and list them alphabetically in order to match
  the style of this file.

f09aa88c33 In newbus land, ivars can only be accessed for direct child, or when
the driver has unholy private knowledge of its great-*cgrandchildren.
The ACPI allocation routine lacked such knowledge when it tried to do
a default allocation for all descendants, rather than just its
immeidate children, so would access grandchild's ivar in an unsafe
way.  This could lead to a panic when devices were present which had
no addresses setup by the BIOS, but which were later allocated in a
lazy manner via pci_alloc_map.  As such, only do the default
allocation adjustments for immediate children.  The manner that
acpi_sysres_find accesses the resource list, used later in
acpi_alloc_resource, is safe and proper so no additional test is
needed there.

This fixes a panic when probing an disabled ata controller on some
newer intel blades.
