5f49915eb2 Change the way options are parsed on the `#!'-line of a shell-script. Instead
of having the kernel parse that line and add an entry to the argument list for
each 'separate word' it finds, have it add only one entry which holds all
the words found on that line.  The old behavior is useful in some situations,
but it does not match the way any other operating system will parse that line.

This has been discussed in the thread "Bug in #! processing - One More Time"
on the freebsd-arch mailing list (starting back on Feb 24, 2005).  The first
few messages in that thread provide the background in much detail.

fd91686850 Use consistent style in functions I want to modify in the near future. 2005-05-27 19:15:46 +00:00
Robert Watson
83b3d58d05 In the current world order, each socket has two mutexes: a mutex
that protects socket and receive socket buffer state, and a second
mutex to protect send socket buffer state.  In some places, the
mutex shared between the socket and receive socket buffer will be
acquired twice, once by each layer, resulting in some
inconsistency, but providing the abstraction benefit of being able
to more easily separate the two mutexes in the future if desired.

When transitioning a socket to the SS_ISDISCONNECTING or
SS_ISDISCONNECTED states, grab the socket/receive socket buffer lock
once rather than grabbing it as the socket lock, modifying socket
state, then grabbing a second time as the receive lock in order to
modify the socket buffer state to indicate no further data can be
read.  This change is believed to close a race between the change in
socket state and the change in socket buffer state, which for a
remotely initiated close on a UNIX domain socket, resulted in
soreceive() returning ENOTCONN rather than an EOF condition.

A similar race still exists in the case of send, however, and is
harder to fix as the socket and send socket buffer mutexes are not
the same, and we would like to avoid holding combinations of socket
mutexes over sb_upcall until we've finished clarifying the locking
protocol for upcalls.

This change has the side affect of reducing the number of mutex
operations to initiate disconnect or perform disconnect on a
socket by two.

886f89afda Back out ipx.h:1.18, which introduced a Linux API compatibility field in
the ipx_net data structure.  Doing so introduced a stronger alignment
requirement for the address structure, which in turn propagated into
other dependent data structures, which turns out not to be suported by
the available IPX source code.  As a result, a number of user space
applications, such as IPX routing components, failed to operate
correctly.

64b5fbaa04 Rewrite of tcp_sack_option(). Kentaro Kurahone (NetBSD) pointed out
that if we sort the incoming SACK blocks, we can update the scoreboard
in one pass of the scoreboard. The added overhead of sorting upto 4
sack blocks is much lower than traversing (potentially) large
scoreboards multiple times. The code was updating the scoreboard with
multiple passes over it (once for each sack option). The rewrite fixes
that, reducing the complexity of the main loop from O(n^2) to O(n).

0a710885bd Add machfb(4), a driver for ATI Mach64 graphics chips intended for
use with syscons(4) on sparc64. It's based on the respective NetBSD
driver with some additional info (initialisation/hardware cursor)
obtained from the Xorg 'ati' driver and some ideas taken from
creator(4). ATI Mach64 chips ("ATI Rage") are quite common as low-
end graphics chips in PCI-based sun4u machines and are used on-board
in e.g. Blade 100 and a couple of OEM products. Most if not all of
the Sun PGX add-on cards family (descriptions of the PGX32 are
conflicting but most say it's a Rage Pro) are also based on these
chips. Depending on the version of the OBP Mach64 cards destined for
use in i386 machines also work in sun4u machines.
The driver uses pixel mode with hardware acceleration as far as
syscons(4) currently permits on sparc64 so text mode is already
quite fast. The hardware cursor is used for the mouse pointer;
for one because this is a "restriction" induced in syscons(4) on
sparc64 by creator(4) and also because of issues with mapping
the aperture when used as a low-level early during boot. Due to
insufficiencies in the available documentation I didn't manage to
get mode switch work properly (sync problems), yet. So for now
this driver relies on the OBP having initialised a mode (as does
creator(4)). On all of the tested machines is even true when using
a serial console (and also not only when the OBP switched to a
serial console because no keyboard is present). In general however
the states the Mach64 chips are left in by the OBP vary a lot
depending on the version of the OBP. This e.g. includes the aperture
not being mapped in even when used as the console and the OBP just
barfing when asked to map it. The latter is also the reason for the
existence of this native driver in FreeBSD rather than taking an
OFW frambuffer approach.
Xorg is also happy to talk to these chips by mmap'ing them through
this driver. For some hardware configs like on the Blade 100 a fix
for the Xorg sparc64 MD bus code is however needed (added in version
6.8.2_2 of the xorg-server port).
The video driver font loading and saving methods are not implemented,
yet, as syscons(4) needs more work in that area to work viable on
sparc64.
With minor modifications machfb(4) would most likely also work on
powerpc, when #ifdef'ing the OFW and possibly implementing mode
setting probably also on the other archs. The latter is however
not very practible at the moment as it would conflict with vga(4).

ff706bdfcf o creator(4):
- Use register macros instead of magic values in the code. [1]
  - Check the return values of OF_getprop() and other stuff that actually
    can fail.
  - Let the unimplemented video driver methods return ENODEV rather
    than 0 so other code isn't tricked into thinking a certain operation
    was successfull. In case of e.g. the video driver creator_ioctl()
    this caused vidcontrol(1) to return random garbage information.
    Remove the TODO macros in the unimplemented video driver methods
    which did a printf("%s: unimplemented\n", __func__). Under certain
    circumstances these managed to invoke a printf() when a low-level
    console device wasn't attached, yet, causing a Fast Data Access MMU
    Miss. These macros were only really usefull for development anyway.
  - Set the struct video_adapter and struct video_info va_flags and
    vi_flags etc. as appropriate.
  - In creator_configure() don't rely on hitting the node which is the
    chosen console device first when searching the OFW tree for adapters
    compatible with this driver. Instead just check whether the chosen
    console device is a viable target for this driver. Targets that are
    not the console (including additional cards in multi-head configs)
    will be attached through creator_upa_attach(). I think this how the
    code in creator_configure() was actually meant to work.
    Honour the VIO_PROBE_ONLY flag and don't initialise and register the
    console device twice when creator_configure() is called a second time
    during sc_probe_unit().
    Let creator_configure() return the number of the found adapters,
    i.e. 1 in case probing succeeds, as it's expected. The return values
    of video adapter configure functions however currently aren't checked
    so this doesn't make a difference at the moment.
  - In creator_upa_attach() don't rely on probing and attaching the
    adapter which is the console first, in case there are multiple
    adpaters and one of them is the console this could lead into using
    the video adapter unit 0 twice.
  - Make the check for DACs with inverted cursor control a bit more
    precise and actually honour that information when turning the cursor
    on or off. Add a helper function creator_cursor_enable() for this
    in order to keep code duplication low. [1]
  - Don't bother with faking a hardware cursor in case a device is the
    console. Apparently this was meant to start kernel output right after
    where the firmware left. In general this isn't worth the fuzz and
    also had no real effect as creator_set_mode() did clear the screen
    in any case, not just in case a device was not the console.
  - Implement creator_fill_rect() and use it to actually blank the
    display in creator_blank_display() when the mode is V_DISPLAY_BLANK,
    moving blanking the display out of creator_set_mode(). Use it also
    to implement creator_set_border() so the border can be re-drawn
    when switching to a VTY from X, exiting X, etc. (which leaves us
    with a black border most of the time).
  - Implement the video driver creator_ioctl(), moving the implementation
    of the IOCTL interface from the fbN CDEV version of creator_ioctl()
    into the video driver version and use the latter to implement the
    former. Use fb_commonioctl() to handle most of the FBIO IOCTLs.
    This gives programs like vidcontrol(1) which use the video driver
    creator_ioctl() a chance of working.
    Implement turning off the cursor via the FBIOSCURSOR IOCTL, which
    Xorg uses to in order to inform the OS that it's taking over the
    cursor. In creator_putm() check whether the cursor is enabled and
    (re-)install it if necessary, moving installing the cursor out of
    creator_init() and into a helper function creator_cursor_install().
    This fixes the missing mouse pointer when switching to a VTY from X,
    exiting X, etc.
  - Some clean-up (remove unused/useless code, etc.).

o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c:
  - Attach syscons(4) as an own pseudo-device on the nexus rather than
    directly in creator_upa_attach(), similiar to attaching syscons(4)
    as a pseudo-device on isa(4) on other archs. This makes it a whole
    lot easier to do the right thing in multi-head configs, especially
    with different types of graphics adapters. [2]
  - Set SC_AUTODETECT_KBD by default so USB keyboards work out of the
    box. [2]

  undocumented scheme at the first parent node than mapping at 'ranges'
  properties. It's however not worth implementing that other scheme and
  actually also fits atkbdc(4) better to just start at the first parent
  node of PS/2 keyboards which is the 8042 controller (I have atkbdc(4)

c592ba5f3f For non-profiling kernels, there were two symbols assigned to the same
address.  One was alltraps_with_regs_pushed, the other was calltrap.

When the stack tracer walks up, it looks for magic symbol names to
determine how to parse non-standard stack frames, such as a trapframe.
It was looking for "calltrap".  Which of the two symbols you got depended
on things like Phase of moon, etc.  If you were unlucky, you got a
garbage stack trace for things like 'debug.trace_on_panic', which would
completely hide the actual source of the problem.

450a94af7a Deal with a few bootstrap issues:
We can't call KeFlushQueuedDpcs() during bootstrap (cold == 1), since
the flush operation sleeps to wait for completion, and we can't sleep
here (clowns will eat us).

On an i386 SMP system, if we're loaded/probed/attached during bootstrap,
smp_rendezvous() won't run us anywhere except CPU 0 (since the other CPUs
aren't launched until later), which means we won't be able to set up
the GDTs anywhere except CPU 0. To deal with this case, ctxsw_utow()
now checks to see if the TID for the current processor has been properly
initialized and sets up the GTD for the current CPU if not.

Lastly, in if_ndis.c:ndis_shutdown(), do an ndis_stop() to insure we
really halt the NIC and stop interrupts from happening.

Note that loading a driver during bootstrap is, unfortunately, kind of
a hit or miss sort of proposition. In Windows, the expectation is that
by the time a given driver's MiniportInitialize() method is called,
the system is already in 'multiuser' state, i.e. it's up and running
enough to support all the stuff specified in the NDIS API, which includes
the underlying OS-supplied facilities it implicitly depends on, such as
having all CPUs running, having the DPC queues initialized, WorkItem
threads running, etc. But in UNIX, a lot of that stuff won't work during
bootstrap. This causes a problem since we need to call MiniportInitialize()
at least once during ndis_attach() in order to find out what kind of NIC
we have and learn its station address.

What this means is that some cards just plain won't work right if
you try to pre-load the driver along with the kernel: they'll only be
probed/attach correctly if the driver is kldloaded _after_ the system
has reached multiuser. I can't really think of a way around this that
would still preserve the ability to use an NDIS device for diskless
booting.

prevent anything from making calls to the NIC while it's being shut down.
This is yet another attempt to stop things like mdnsd from trying to
poke at the card while it's not properly initialized and panicking
the system.

correct it themselves and at least for the USB controller part
the intpin register is truely hardwired to 0 and can't be changed.
This means that we would have to hook up the quirk information

  the century in the driver).
- Add the MI part of interfacing the watchdog functionality of MK48Txx with
  extended registers with watchdog(9). This is inspired by the SunOS/Solaris
  drivers for the 'eeprom' devices also having watchdog support. I actually
  expected this to work out of the box on Sun Exx00 machines with 'eeprom'
  devices which have a 'watchdog-enable' property. On terminal count of the
  the watchdog timer however only the MK48TXX_FLAGS_WDF bit rises but the
  reset signal and the interrupt respectively (depending on whether the
  MK48TXX_WDOG_WDS bit of the chip and the MK48TXX_WDOG_ENABLE_WDS flag
  of the driver respectively is set) goes nowhere. Apparently passing the
  reset signal on to the WDR line of the CPUs has to be enabled somewhere
  else but we don't have documentation for the Exx00 specific controllers.
  I decided to commit this nevertheless so it can be enabled in the eeprom(4)
  front-end later in e.g. 6.0-STABLE without breaking the API. Besides the
  Exx00 the watchdog part of the MK48Txx should also work on E250 and E450.
  Possibly also without extra fiddling on these machines but I haven't
  found someone willing to give it a try on such a machine so far.
- Use uintXX_t instead of u_intXX_t, use __func__ instead of hardcoded

a0b2f8d7fc - Collapse eeprom_ebus.c and eeprom_sbus.c into eeprom.c and
eeprom_ebus_attach() and eeprom_sbus_attach() into eeprom_attach()
  respectively. Since the introduction of the ofw_bus interface some
  time ago and now that ebus(4) also uses SYS_RES_MEMORY for the
  memory resources since ebus.c rev. 1.22 there is no longer a
  need to have separate front-ends for ebus(4), fhc(4) and sbus(4).
- Fail gracefully instead of panicing when the model can't be
  determined.
- Don't leak resources when mk48txx_attach() fails.
- Use FBSDID.

176da80446 - Artificially using SYS_RES_IOPORT for EBus devices for reasons of
compatibility with ISA devices while in fact all known EBus devices
  actually use memory space turned out to be not a good idea as so far
  there is only the 'rtc' device known to show up either on an EBus or
  ISA bus but not on any of the other busses used on sparc64. However
  there are quite a couple of them that show up on either EBus, FireHose
  or SBus. In order to save extra code in the respective drivers switch
  ebus(4) to actually use SYS_RES_MEMORY for the memory resources of
  its children. At least for transition still accept SYS_RES_IOPORT
  and silently change it to SYS_RES_MEMORY. [1]
- In ebus_probe() use ofw_bus_get_name() instead of re-implementing it
  via ofw_bus_get_node() and OF_getprop().
- Remove some unused variables.
- Use FBSDID.

42be1191a0 - When iterating over the register resources of the children don't use
the iteration variable as the RID when adding the respective resource
  to the child via bus_set_resource(). In case a device has both I/O
  and memory resources this generates gaps in the newbus resources of
  the child, e.g. its first memory resource might end up as RID 1.
  To solve this mimic resource_list_add_next() via resource_list_find()
  and bus_set_resource(); we can't just use resource_list_add_next()
  here as this would circumvent the limit checks in isa_set_resource()
  of the common ISA code.
  This however is more or less a theoretical problem so far as all known
  ISA devices on sparc64 soley use I/O space.
- Just use bus_generic_rl_release_resource() for isa_release_resource()
  instead of re-implementing the former.
- Improve some comments to better reflect reality, minor clean-up and
  simplifications, return NULL instead of 0 were appropriate.

65fb49a994 - Try to not leak resources in the attach functions of the esp(4) SBus
front-end and the LSI64854 and NCR53C9x code in case one of these
  functions fails. Add detach functions to these parts and make esp(4)
  detachable.
- Revert rev. 1.7 of esp_sbus.c, since rev. 1.34 of sbus.c the clockfreq
  IVAR defaults to the per-child values.
- Merge ncr53c9x.c rev. 1.111 from NetBSD (partial):
  On reset, clear state flags and the msgout queue.
  In NetBSD code to notify the upper layer (i.e. CAM in FreeBSD) on reset
  was also added with this revision. This is believed to be not necessary
  in FreeBSD and was not merged.
  This makes ncr53c9x.c to be in sync with NetBSD up to rev. 1.114.
- Conditionalize the LSI64854 support on sbus(4) only instead of sbus(4)
  and esp(4) as it's also required for the 'dma', 'espdma' and 'ledma'
  busses/devices as well as the 'SUNW,bpp' device (printer port) which
  all hang off of sbus(4).
- Add a driver for the 'dma', 'espdma' and 'ledma' (pseudo-)busses/
  devices. These busses and devices actually represent the LSI64854 DMA
  engines for the ESP SCSI and LANCE Ethernet controllers found on the
  SBus of Ultra 1 and SBus add-on cards. With 'espdma' and 'ledma' the
  'esp' and 'le' devices hang off of the respective DMA bus instead of
  directly from the SBus. The 'dma' devices are either also used in this
  manner or on some add-on cards also as a companion device to an 'esp'
  device which also hangs off directly from the SBus. With the latter
  variant it's a bit tricky to glue the DMA engine to the core logic of
  the respective 'esp' device. With rev. 1.35 of sbus.c we are however
  guaranteed that such a 'dma' device is probed before the respective
  'esp' device which simplifies things a lot. [1]
- In the esp(4) SBus front-end read the part-unique ID code of Fast-SCSI
  capable chips the right way. This fixes erroneously detecting some
  chips as FAS366 when in fact they are not. Add explicit checks for the
  FAS100A, FAS216 and FAS236 variants instead treating all of these as
  ESP200. That way we can correctly set the respective Fast-SCSI config
  bits instead of driving them out of specs. This includes adding the
  FAS100A and FAS236 variants to the NCR53C9x core code. We probably
  still subsume some chip variants as ESP200 while in fact they are
  another variant which however shouldn't really matter as this will
  only happen when these chips are driven at 25MHz or less which implies
  not being able to run Fast-SCSI. [3]
- Add a workaround to the NCR53C9x interrupt handler which ignores the
  stray interrupt generated by FAS100A when doing path inquiry during
  boot and which otherwiese would trigger a panic.
- Add support for the 'esp' devices hanging off of a 'dma' or 'espdma'
  busses or which are companions of 'dma' devices to esp(4). In case of
  the variants that hang off of a DMA device this is a bit hackish as
  esp(4) then directly uses the softc of the respective parent to talk
  to the DMA engine. It might make sense to add an interface for this
  in order to implement this in a cleaner way however it's not yet clear
  how the requirements for the LANCE Ethernet controllers are and the
  hack works for now. [2]
  This effectively adds support for the onboard SCSI controller in
  Ultra 1 as well as most of the ESP-based SBus add-on cards to esp(4).
  With this the code for supporting the Performance Technologies SBS430
  SBus SCSI add-on cards is also largely in place the remaining bits
  were however omitted as it's unclear from the NetBSD how to couple
  the DMA engine and the core logic together for these cards.

410f3d914e - Add an IVAR for retrieving the interrupt group number of the parent Sbus
device and which also applies to the children. This is very usefull for
  drivers for the various subordinate busses so they don't need to fiddle
  with the OFW node of their parent themselves. As SBus busses hang of the
  nexus and we don't use the ofw_bus interface for nexus devices, yet, this
  would also require special knowledge about this in the drivers for the
  SBus children which these shouldn't need to have.
  This includes switching to use an unshifted IGN in the sc_ign member of
  the sbus(4) softc internally.
- For SBus child devices where there are variants that are actually split
  split into two SBus devices (as opposed to the first half of the device
  being a SBus device and the second half hanging off of the first one)
  like 'auxio' and 'SUNW,fdtwo' or 'dma' and 'esp' probe the SBus device
  which is a prerequisite to the driver attaching to the second one with
  a lower order. This saves us from dealing with different probe orders
  in the respective device drivers which generally is more hackish.
- Remove a stale comment about the 'specials' array above the attaching
  of the child devices. This is a remnant of the NetBSD/sparc origin of
  this code. There the 'specials' array is also used to probe certain
  devices which are prerequisites to others first. Why NetBSD soley
  relies on the devices having the expected order in the OFW tree on
  sparc64 isn't clear to me, as far as I can tell OFW doesn't guaranteed
  such things.

a9f9f6ce08 Change ofw_readin/ofw_copyin to map the entire region before

too many single-page mappings, and eventually OFW overflowed

The new algorithm creates far less mappings and fixed a bug
where multiple mappings for the same page would be created.

'Twas known this was a problem, but only became urgent when the
install CD's mfs_root grew large enough to cause the overflow.

0621191ab9 Fix some of the things I broke so that the SMC2602W (AMD Am1772) driver
works again.

This driver uses NdisScheduleWorkItem(), and we have to take special steps
to insure that its workitems don't collide with any of the other workitems
used by the NDISulator. In particular, if one of the driver's work jobs
blocks, it can prevent NdisMAllocateSharedMemoryAsync() from completing
when expected.

The original hack to fix this was to have NdisMAllocateSharedMemoryAsync()
defer its work to the DPC queue instead of the general task queue. To
fix it now, I decided to add some additional workitem threads. (There's
supposed to be a pool of worker threads in Windows anyway.) Currently,
there are 4. There should be at least 2. One is reserved for the legacy
ExQueueWorkItem() API, while the others are used in round-robin by the
IoQueueWorkItem() API. NdisMAllocateSharedMemoryAsync() uses the latter
API while NdisScheduleWorkItem() uses the former, so the deadlock is
avoided.

Fixed NdisMRegisterDevice()/NdisMDeregisterDevice() to work a little
more sensibly with the new driver_object/device_object framework. It
doesn't really register a working user-mode interface, but the existing
code was completely wrong for the new framework.

Fixed a couple of bugs dealing with the cancellation of events and
DPCs. When cancelling an event that's still on the timer queue (i.e.
hasn't expired yet), reset dh_inserted in its dispatch header to FALSE.
Previously, it was left set to TRUE, which would make a cancelled
timer appear to have not been cancelled. Also, when removing a DPC
from a queue, reset its list pointers, otherwise a cancelled DPC
might mistakenly be treated as still pending.

Lastly, fix the behavior of ntoskrnl_wakeup() when dealing with
objects that have nobody waiting on them: sync event objects get
their signalled state reset to FALSE, but notification objects
should still be set to TRUE.

433d61bb56 Add support for NdisMEthIndicateReceive() and MiniportTransferData().
The Ralink RT2500 driver uses this API instead of NdisMIndicateReceivePacket().

Drivers use NdisMEthIndicateReceive() when they know they support
802.3 media and expect to hand their packets only protocols that want
to deal with that particular media type. With this API, the driver does
not manage its own NDIS_PACKET/NDIS_BUFFER structures. Instead, it
lets bound protocols have a peek at the data, and then they supply
an NDIS_PACKET/NDIS_BUFFER combo to the miniport driver, into which
it copies the packet data.

Drivers use NdisMIndicateReceivePacket() to allow their packets to
be read by any protocol, not just those bound to 802.3 media devices.

To make this work, we need an internal pool of NDIS_PACKETS for
receives. Currently, we check to see if the driver exports a
MiniportTransferData() method in its characteristics structure,
and only allocate the pool for drivers that have this method.

This should allow the RT2500 driver to work correctly, though I
still have to fix ndiscvt(8) to parse its .inf file properly.

Also, change kern_ndis.c:ndis_halt_nic() to reap timers before
acquiring NDIS_LOCK(), since the reaping process might entail sleeping
briefly (and we can't sleep with a lock held).
