80e963994a Fixup locking and mark MPSAFE.
- Add locked variants of init() and start().
- Use callout_*() to manage callout.
- Test IFF_DRV_RUNNING rather than IFF_UP in wb_intr() to see if we are
  still active when an interrupt comes in.

I couldn't find any of these cards anywhere to test on myself, and google
turns up references to FreeBSD and OpenBSD manpages for this driver when
trying to locate a card that way.  I'm not sure anyone actually uses these
cards with FreeBSD.

2bf266e6da - Add locking and mark MPSAFE. The driver had a mutex in the softc and

- Use callout_*() to manage the callout.
- Use m_devget() to copy data out of the rx buffers rather than doing it
  all by hand.
- Use m_getcl() to allocate mbuf clusters rather than doing it all by hand.
- Don't free the software descriptor for a rx ring entry if we can't
  allocate an mbuf cluster for it.  We left a dangling pointer and never
  reallocated the entry anyway.  OpenBSD's code (from which this was
  derived) has the same bug.

2851f51eb1 Revert most of revision 1.235 and fix the problem a different way. We
can't acquire an sx lock in ttyinfo() because ttyinfo() can be called
from interrupt handlers (such as atkbd_intr()).  Instead, go back to
locking the process group while we pick a thread to display information for
and hold that lock until after we drop sched_lock to make sure the
process doesn't exit out from under us.  sched_lock ensures that the
specific thread from that process doesn't go away.  To protect against
the process exiting after we drop the proc lock but before we dereference
it to lookup the pid and p_comm in the call to ttyprintf(), we now copy
the pid and p_comm to local variables while holding the proc lock.

This problem was found by the recently added TD_NO_SLEEPING assertions for
interrupt handlers.

51d6d0952b Clean up and apply the fix for PR 83477. The calculation for locating
the start of the section headers has to take into account the fact
that the image_nt_header is really variable sized. It happens that
the existing calculation is correct for _most_ production binaries
produced by the Windows DDK, but if we get a binary with oddball
offsets, the PE loader could crash.

Changes from the supplied patch are:

- We don't really need to use the IMAGE_SIZEOF_NT_HEADER() macro when
  computing how much of the header to return to callers of
  pe_get_optional_header(). While it's important to take the variable
  size of the header into account in other calculations, we never
  actually look at anything outside the non-variable portion of the
  header. This saves callers from having to allocate a variable sized
  buffer off the heap (I purposely tried to avoid using malloc()
  in subr_pe.c to make it easier to compile in both the -D_KERNEL and
  !-D_KERNEL case), and since we're copying into a buffer on the
  stack, we always have to copy the same amount of data or else
  we'll trash the stack something fierce.

- We need <stddef.h> to get offsetof() in the !-D_KERNEL case.

- ndiscvt.c needs the IMAGE_FIRST_SECTION() macro too, since it does
  a little bit of section pre-processing.

7f3cc43211 Get rid of the timer tracking and reaping code in NdisMInitializeTimer()
and ndis_halt_nic(). It's been disabled for some time anyway, and
it turns out there's a possible deadlock in NdisMInitializeTimer() when
acquiring the miniport block lock to modify the timer list: it's
possible for a driver to call NdisMInitializeTimer() when the miniport
block lock has already been acquired by an earlier piece of code. You
can't acquire the same spinlock twice, so this can deadlock.

Also, implement MmMapIoSpace() and MmUnmapIoSpace(), and make
NdisMMapIoSpace() and NdisMUnmapIoSpace() use them. There are some
drivers that want MmMapIoSpace() and MmUnmapIoSpace() so that they can
map arbitrary register spaces not directly associated with their
device resources. For example, there's an Atheros driver for
a miniPci card (0x168C:0x1014) on the IBM Thinkpad x40 that wants
to map some I/O spaces at 0xF00000 and 0xE00000 which are held by
the acpi0 device. I don't know what it wants these ranges for,
but if it can't map and access them, the MiniportInitialize() method
fails.

80f006a1e3 If we're trying to use C2/3 and reads from the register are returning
immediately, back off to the next higher Cx sleep state.  Some machines
with a Via chipset report a valid C3 but a register read doesn't actually
halt the CPU.  This would cause the machine to appear unresponsive as it
repeatedly called cpu_idle() which immediately returned.  Causing interrupts
(i.e. by pressing the power button) would cause the system to make forward
progress, showing that it wasn't actually hung.

Also, enable interrupts a little earlier.  We don't need them disabled
to calculate the delta time for the read.

e0f66ef861 Reorganize the interrupt handling code a bit to make a few things cleaner
and increase flexibility to allow various different approaches to be tried
in the future.
- Split struct ithd up into two pieces.  struct intr_event holds the list
  of interrupt handlers associated with interrupt sources.
  struct intr_thread contains the data relative to an interrupt thread.
  Currently we still provide a 1:1 relationship of events to threads
  with the exception that events only have an associated thread if there
  is at least one threaded interrupt handler attached to the event.  This
  means that on x86 we no longer have 4 bazillion interrupt threads with
  no handlers.  It also means that interrupt events with only INTR_FAST
  handlers no longer have an associated thread either.
- Renamed struct intrhand to struct intr_handler to follow the struct
  intr_foo naming convention.  This did require renaming the powerpc
  MD struct intr_handler to struct ppc_intr_handler.
- INTR_FAST no longer implies INTR_EXCL on all architectures except for
  powerpc.  This means that multiple INTR_FAST handlers can attach to the
  same interrupt and that INTR_FAST and non-INTR_FAST handlers can attach
  to the same interrupt.  Sharing INTR_FAST handlers may not always be
  desirable, but having sio(4) and uhci(4) fight over an IRQ isn't fun
  either.  Drivers can always still use INTR_EXCL to ask for an interrupt
  exclusively.  The way this sharing works is that when an interrupt
  comes in, all the INTR_FAST handlers are executed first, and if any
  threaded handlers exist, the interrupt thread is scheduled afterwards.
  This type of layout also makes it possible to investigate using interrupt
  filters ala OS X where the filter determines whether or not its companion
  threaded handler should run.
- Aside from the INTR_FAST changes above, the impact on MD interrupt code
  is mostly just 's/ithread/intr_event/'.
- A new MI ddb command 'show intrs' walks the list of interrupt events
  dumping their state.  It also has a '/v' verbose switch which dumps
  info about all of the handlers attached to each event.
- We currently don't destroy an interrupt thread when the last threaded
  handler is removed because it would suck for things like ppbus(8)'s
  braindead behavior.  The code is present, though, it is just under
  #if 0 for now.
- Move the code to actually execute the threaded handlers for an interrrupt
  event into a separate function so that ithread_loop() becomes more
  readable.  Previously this code was all in the middle of ithread_loop()
  and indented halfway across the screen.
- Made struct intr_thread private to kern_intr.c and replaced td_ithd
  with a thread private flag TDP_ITHREAD.
- In statclock, check curthread against idlethread directly rather than
  curthread's proc against idlethread's proc. (Not really related to intr
  changes)

d24864f785 Refactor (some more) installation of kernel and module objects.
Try to make everyone happy: David (to have debug kernels installed
by default), Warner (to be able to override that), and myself (for
actually making it all work and to be consistent).

Now, if kernel was configured for debugging (through DEBUG=-g in
the kernel config file or "config -g"), doing "make install" will
install debug versions of kernel and module objects with their
canonical names,

	kernel.debug -> /boot/kernel/kernel
	if_fxp.ko.debug -> /boot/kernel/if_fxp.ko

Installing a kernel not configured for debugging, or debug kernel
with INSTALL_NODEBUG variable defined, will install non-debug
kernel and module objects.

Also, restore the install.debug and reinstall.debug targets that
are part of the existing API (they cause some additional gdb(1)
scripts to be installed).

85155d23de Add a 1 microsecond delay in pci_add_children(), right before the read
of the PCIR_HDRTYPE register. It's the value returned from this
read access that determines whether or not we decide a device is
present at the current slot index. For some reason that I can't
adequately explain, this read fails on my machine when probing the
USB controller on my machine (which happens a multifunction device
at slot index 3 hung off the PCI-PCI bridge on the AMD8111 (bus
index 1)). The read will return 0xFF even though it should return
0x80 to indicate the presence of a multifunction device.

As near as I can tell, there's some timing issue involved with reading
the 'dead' slot indexes 0 through 2 that causes the read of the actual
device at slot 3 to fail. I tried a couple of different tricks to
correct the problem (the patch to amd64/pci/pci_cfgreg.c fixes it
for the amd64 arch), but adding this delay is the only thing that
always allows the USB controllers to be correctly probed 100% of the
time. Whatever the problem is, it's likely confined to the AMD8111
chipset. However, a simple 1us delay is fairly harmless and should
have no side effects for other hardware. I consider this to be
voodoo, but it's fairly benign voodoo and it makes my USB keyboard
and mouse work again.

Note that this is the second time that I've had to resort to a
1us delay to fix a PCI-related problem with this AMD8111/Opteron
system (the first being a fix I made a while back to the NDISulator).
It's possible the delay really belongs in the cfgreg code itself,
or that pci_cfgreg needs some custom hackery for an errata in the
8111. (I checked but couldn't find any documented errata on AMD's
site that could account for these problems.)

ba3af76df7 Modify the pci_cfgdisable() routine to bring it more in line with
other OSes (Solaris, Linux, VxWorks). It's not necessary to write a 0
to the config address register when using config mechanism 1 to turn
off config access. In fact, it can be downright troublesome, since it
seems to confuse the PCI-PCI bridge in the AMD8111 chipset and cause
it to sporadically botch reads from some devices. This is the cause
of the missing USP ports problem I was experiencing with my Sun Opteron
system.

Also correct the case for mechanism 2: it's only necessary to write
a 0 to the ENABLE port.

2a0146bdf1 Preliminary support for Xircom Credit Card Adapter. Not to be
confused with the Credit Card Adapter II and its spawn (which the xe
driver supports).  These changes get my card probing and attaching.  I
recently won one of these (and a NEC rebadged version) in an lot
auction.  The NEC didn't work, so I took it apart and found the
MB86960A chip and then modified if_fe_pccard.c to attach.  I can't
test this card further since I have no dongle for this card.

697ca17bb0 Back out most of 1.84. It was unwise to force debug kernels to always
be installed.  It should have been optional to install a non-debug
one, just like it was formerly optional to install a debug one.  In
order to do that, most of 1.84 had to go.

Instead, make installing the debug kernel the default, but create a
new option INSTALL_NODEBUG for those people that have small /
partitions and good source control habits.

This preserves the behavior of 1.84 while allowing it to be overriden
for people (like me) that do not have the time to upgrade to get a
bigger / and also don't have time for stupid makefile tricks when
upgrading their older system, but still want a kernel.debug around if
things go south.

58553b9925 Rename the KDB_STOP_NMI kernel option to STOP_NMI and make it apply to all
IPI_STOP IPIs.
- Change the i386 and amd64 MD IPI code to send an NMI if STOP_NMI is
  enabled if an attempt is made to send an IPI_STOP IPI.  If the kernel
  option is enabled, there is also a sysctl to change the behavior at
  runtime (debug.stop_cpus_with_nmi which defaults to enabled).  This
  includes removing stop_cpus_nmi() and making ipi_nmi_selected() a
  private function for i386 and amd64.
- Fix ipi_all(), ipi_all_but_self(), and ipi_self() on i386 and amd64 to
  properly handle bitmapped IPIs as well as IPI_STOP IPIs when STOP_NMI is
  enabled.
- Fix ipi_nmi_handler() to execute the restart function on the first CPU
  that is restarted making use of atomic_readandclear() rather than
  assuming that the BSP is always included in the set of restarted CPUs.
  Also, the NMI handler didn't clear the function pointer meaning that
  subsequent stop and restarts could execute the function again.
- Define a new macro HAVE_STOPPEDPCBS on i386 and amd64 to control the use
  of stoppedpcbs[] and always enable it for i386 and amd64 instead of
  being dependent on KDB_STOP_NMI.  It works fine in both the NMI and
  non-NMI cases.

3924da21a3 - Rename 'traceall' to 'alltrace' so that the 'tr' shortcut for 'trace'
still works.  Also, this is consistent with 'show pcpu' vs
  'show allpcpu'.  (And 'show allstacks' on OS X for that matter.)
- Add 'bt' as an alias for 'trace'.  We already have a 'where' alias as
  well, so this makes it easier for gdb-wired hands to work in ddb.

a7e59a7679 Import ACPI smart battery support. Newer systems (Acer, mostly) do not
support the CM-battery interface.  Smart batteries can eventually be
supported without ACPI via a separate SMBus interface.  The ACPI interface
uses the embedded controller for reading/writing to the SMBus, and normal
ASL definitions for locating the battery controller (since SMBus can't be
enumerated.)  Also import definitions for the smart battery interface.

This was written by Hans Petter Selasky with minor cleanups from myself.

9aa72f7404 Cleanups and support code for importing smart battery support.
* Use ACPI_BATT_UNKNOWN instead of constants
* Use maxunit instead of a count of devices since we may have sparse
  battery devices in the future.  Only userland should be using unit
  numbers anyway, so provide a translation function.  (Kernel use of
  batteries should be restricted to looking up a device_t and calling
  methods directly.
* Don't check acpi_BatteryIsPresent() in acpi_battery.  Leave it up to
  the hardware-specific driver (i.e. cmbat) since smart batteries seem
  to not report the "battery present" flag.
* Convert mA to mW if the battery uses those units.  CM-batteries only
  used mW so this deficiency went unnoticed.
* Clean strings reported in the battery info from any control chars.
* Only dereference the unit from ioctl_arg if the full struct is present.
  Unit wouldn't have been used later if it wasn't present but this is
  cleaner.  Translate the unit if it's not ACPI_BATTERY_ALL_UNITS.
* bzero structs before returning them to usermode for future compat.

Most of this work was submitted by Hans Petter Selasky and then majorly
reworked by myself.

a50286e21d Make the multiple DPC threads an option, and create only one by default.
This avoids the need for sched_bind() in the default case so that you
can start up the NDIS subsystem at boot time when only CPU 0 is running.

There are potentially ways to fix it so that the DPC threads aren't
started until after the other CPUs are launched, but doing it correctly
is tricky. You need to defer the startup of the ntoskrnl subsystem
(ntoskrnl_libinit()), not just defer ndis_attach().

For now, I don't think it will make much difference having just the
single DPC thread (I started out with just one anyway). Note that this
turns the KeSetTargetProcessorDpc() routine into a no-op, since the
CPU number in struct kdpc is now ignored.

201aec8321 In the ISA case, we call ed_probe_WD80x3 before we call
ed_probe_rtl80x9.  In the pci case we call ed_probe_rtl80x9 first.  In
the PCI case we were using the correct nic_offset by accident because
softc is initialized to zero.  In the isa case we were using the wrong
value by accident, since ed_probe_WD80x3 sets the offset value to
0x10.  This lead to the identification routines failing.  Fix this
problem by always initalizing the nic_offset and asic_offset before
making ed_{asic,nic}_{in,out}* calls.

135c43dc52 Fix a bug in the kernel module runtime linker that made it impossible
to unload the usb.ko module after boot if it was originally preloaded
from "/boot/loader.conf".  When processing preloaded modules, the
linker erroneously added self-dependencies the each module's reference
count.  That prevented usb.ko's reference count from ever going to 0,
so it could not be unloaded.

a3ced67adf Another round of cleanups and fixes:
- Change ndis_return() from a DPC to a workitem so that it doesn't
  run at DISPATCH_LEVEL (with the dispatcher lock held).

- In if_ndis.c, submit packets to the stack via (*ifp->if_input)() in
  a workitem instead of doing it directly in ndis_rxeof(), because
  ndis_rxeof() runs in a DPC, and hence at DISPATCH_LEVEL. This
  implies that the 'dispatch level' mutex for the current CPU is
  being held, and we don't want to call if_input while holding
  any locks.

- Reimplement IoConnectInterrupt()/IoDisconnectInterrupt(). The original
  approach I used to track down the interrupt resource (by scanning
  the device tree starting at the nexus) is prone to problems when
  two devices share an interrupt. (E.g removing ndis1 might disable
  interrupts for ndis0.) The new approach is to multiplex all the
  NDIS interrupts through a common internal dispatcher (ntoskrnl_intr())
  and allow IoConnectInterrupt()/IoDisconnectInterrupt() to add or
  remove interrupts from the dispatch list.

- Implement KeAcquireInterruptSpinLock() and KeReleaseInterruptSpinLock().

- Change the DPC and workitem threads to use the KeXXXSpinLock
  API instead of mtx_lock_spin()/mtx_unlock_spin().

- Simplify the NdisXXXPacket routines by creating an actual
  packet pool structure and using the InterlockedSList routines
  to manage the packet queue.

- Only honor the value returned by OID_GEN_MAXIMUM_SEND_PACKETS
  for serialized drivers. For deserialized drivers, we now create
  a packet array of 64 entries. (The Microsoft DDK documentation
  says that for deserialized miniports, OID_GEN_MAXIMUM_SEND_PACKETS
  is ignored, and the driver for the Marvell 8335 chip, which is
  a deserialized miniport, returns 1 when queried.)

- Clean up timer handling in subr_ntoskrnl.

- Add the following conditional debugging code:
	NTOSKRNL_DEBUG_TIMERS - add debugging and stats for timers
	NDIS_DEBUG_PACKETS - add extra sanity checking for NdisXXXPacket API
	NTOSKRNL_DEBUG_SPINLOCKS - add test for spinning too long

- In kern_ndis.c, always start the HAL first and shut it down last,
  since Windows spinlocks depend on it. Ntoskrnl should similarly be
  started second and shut down next to last.

60d41c425b - Use BUS_DMASYNC_PREWRITE in em_get_buf(), as the adapter is about to read

- In em_process_receive_interrupts(), call bus_dmamap_sync() for the
descriptors set each time we modify one descriptor, instead of doing it only
at the function exit, to make sure the adapters know he can re-use the
descriptor.
This helps on arm with write-back data cache (and possibly on other arches

if we attempt to process more than num_rx_desc descriptors, the adapter
would just stop processing rx interrupts.

1a330eb01d Add support for kernel modules with a single PT_LOAD section.
While here, support up to four sections because it was trivial to do
and cheap. (One pointer per section).

For amd64 with "-fpic -shared" format .ko files, using a single PT_LOAD
section is important to avoid wasting about 1MB of KVM and physical ram
for the 'gap' between the two PT_LOAD sections.  amd64 normally uses
.o format kld files and isn't affected normally.  But -fpic -shared modules
are actually possible to produce and load...  (And with a bugfix to
binutils, we can build and use plain -shared .ko files without -fpic)

i386 only wastes 4K per .ko file, so that isn't such a big deal there.

12d360453c Close a race in the ufs_lookup() code that handles the ISDOTDOT
case by saving the value of dp->i_ino before unlocking the vnode
for the current directory and passing the saved value to VFS_VGET().

Without this change, another thread can overwrite dp->i_ino after
the current directory is unlocked, causing  ufs_lookup() to lock
and return the wrong vnode in place of the vnode for its parent
directory.  A deadlock can occur if dp->i_ino was changed to a
subdirectory of the current directory because the root to leaf vnode
lock ordering will be violated.  A vnode lock can be leaked if
dp->i_ino was changed to point to the current directory, which
causes the current vnode lock for the current directory to be
recursed, which confuses lookup() into calling vrele() when it
should be calling vput().

The probability of this bug being triggered seems to be quite low
unless the sysctl variable debug.vfscache is set to 0.

3c2adf40e9 Add a default value for VM_BCACHE_SIZE_MAX of 400MB. This is copied from
amd64, and is a factor of 3 less than the value previously auto-sized on
a 12GB machine, which would cause an overflow in calculations involving the
maxbcache int, causing bufinit() to loop forever at boot.

728ef95410 The signal code is now an int rather than a long, so update debug printfs. 2005-10-14 20:22:57 +00:00
Kris Kennaway
f098dcded5 Partially revert revision 1.66, which contained a change that did not
correspond to the commit log.  It changed the maxswzone and maxbcache
parameters from int to long, without changing the extern definitions
in <sys/buf.h>.

In fact it's a good thing it did not, because other parts of the system
are not yet ready for this, and on large-memory sparc machines it causes
severe filesystem damage if you try.

The worst effect of the change was that the tunables controlling the
above variables stopped working.  These were necessary to allow such
large sparc64 machines (with >12GB RAM) to boot, since sparc64 did not
set a hard-coded upper limit on these parameters and they ended
up overflowing an int, causing an infinite loop at boot in bufinit().

823acd70b6 Regen for sigqueue syscall. 2005-10-14 12:56:28 +00:00
David Xu
9104847f21 1. Change prototype of trapsignal and sendsig to use ksiginfo_t *, most
changes in MD code are trivial, before this change, trapsignal and
   sendsig use discrete parameters, now they uses member fields of
   ksiginfo_t structure. For sendsig, this change allows us to pass
   POSIX realtime signal value to user code.

2. Remove cpu_thread_siginfo, it is no longer needed because we now always
   generate ksiginfo_t data and feed it to libpthread.

3. Add p_sigqueue to proc structure to hold shared signals which were
   blocked by all threads in the proc.

4. Add td_sigqueue to thread structure to hold all signals delivered to
   thread.

5. i386 and amd64 now return POSIX standard si_code, other arches will
   be fixed.

6. In this sigqueue implementation, pending signal set is kept as before,
   an extra siginfo list holds additional siginfo_t data for signals.
   kernel code uses psignal() still behavior as before, it won't be failed
   even under memory pressure, only exception is when deleting a signal,
   we should call sigqueue_delete to remove signal from sigqueue but
   not SIGDELSET. Current there is no kernel code will deliver a signal
   with additional data, so kernel should be as stable as before,
   a ksiginfo can carry more information, for example, allow signal to
   be delivered but throw away siginfo data if memory is not enough.
   SIGKILL and SIGSTOP have fast path in sigqueue_add, because they can
   not be caught or masked.
   The sigqueue() syscall allows user code to queue a signal to target
   process, if resource is unavailable, EAGAIN will be returned as
   specification said.
   Just before thread exits, signal queue memory will be freed by
   sigqueue_flush.
   Current, all signals are allowed to be queued, not only realtime signals.

66e58c20dd From the PR:
The receive function em_process_receive_interrupts() unlocks the
  adapter while ether_input() processes the packet, and then locks
  it back. In the meantime, em_init() may be called, either from
  em_watchdog() from softclock interrupt or from the ifconfig(8)
  program. The em_init() resets the card, in particular it sets
  adapter->next_rx_desc_to_check to 0 and resets hardware RX Head
  and Tail descriptor pointers. The loop in
  em_process_receive_interrupts() does not expect these things to
  change, and a mess may result.

This fixes long wedges of em(4) interfaces receive part under high
load and IP fastforwarding enabled.

that, but there's no reason we can't use qemu's emulation w/o these
