6937461ee9 Remove mfsvr():
o  The function is defined unconditionally but depends on SPR_SVR,
   which is defined conditionally.
o  spr.h defines mfspr() and mtspr(), which is no worse to use.

ae11a989e6 When writing trailers in sendfile(2), don't call kern_writev()
while holding the socket buffer lock.  These leads to an
immediate panic due to recursing the socket buffer lock.  This
bug was introduced in uipc_syscalls.c:1.240, but masked by
another bug until that was fixed in uipc_syscalls.c:1.269.

Note that the current fix isn't perfect, but better than
panicking: normally we guarantee that simultaneous invocations
of a system call to write on a stream socket won't be
interlaced, which is ensured by use of the socket buffer sleep
lock.  This is guaranteed for the sendfile headers, but not
trailers.  In practice, this is likely not a problem, but
should be fixed.

5318f8408b Add a breif example for the wlan change. Include an explicit pointer
to rc.conf(5) to remind people where to look for all the details.
People without network connectivity forget basics like this...  This
is in keeping with historic UPDATING entries which try to provide
basic information in the entry, and a pointer to more extensive
information documenting the new thing.

3086a7a9b4 MFamd64 revision 1.544/i386 revision 1.549
Retire pmap_track_modified().  We no longer need it because we do not
  create managed mappings within the clean submap.  To prevent regressions,
  add assertions blocking the creation of managed mappings within the clean
  submap.

46c00da6b5 Include the QUICC bus front-end in the module for PowerPC. 2008-04-26 18:41:42 +00:00
Marcel Moolenaar
6239f9e5f1 With rev 1.24 of sys/powerpc/powermac/macio.c, we now get a
total of 6 interrupt resources for scc(4) on macio(4). This
is 3 per channel, of which the 1st of each channel is the
interrupt associated with the SCC. The other 2 are for DMA
operation.
Change scc_bfe_attach() to accept an argument that's the
number of interrupts per channel (ipc) and change each bus
front-end (bfe) to pass that argument through a wrapper
for the device_attach method.

For now, we only allocate the 1st interrupt of each channel
to perserve behaviour.

4924db935d Take into account the size of the interrupt cell. It's determined
by the parent for interrupt resources. This corrects parsing of
the interrupts property.

With parsing of the property fixed, add all interrupts to the
resource list. Bump the max. number of interrupts from 5 to 6
as scc(4) attached to macio(4) has 6 interrupts (3 per channel).

c15fccb8f2 - Use the revamped code from the gem(4) PCI front-end, which
doesn't require parts of the Expansion ROM to be copied around,
  for obtaining the MAC address on !OFW platforms.
- Don't unnecessarily cache bus space tag and handle nor RIDs
  in the softcs of the front-ends.
- Don't use function calls in initializers.
- Let the SBus front-end depend on sbus(4).

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.
