safe - we can't afford to take a TLB trap when we are writing a
trapframe. Possibly revisit this later.
* Various fixes to pmap_enter() so that it actually works properly.
This shouldn't affect the alpha or ia64, since they don't have a
variable named astpending. The alpha still has 2 declarations of
this nonexistent variable.
the #includes to the respective source files.
Also un-nest includes in <dev/hfa/fore_include.h>
I have run src/tools/tools/kerninclude to remove 1239 clearly
unneeded #includes reducing the total from 3524 includes to 2285.
Define the NETISR just like all the other NETISRs.
unifdef -Usun -D__FreeBSD__ we will probably never support sun4c
and if we do we can't use the solaris code anyway and I doubt
anybody will be running Fore ATM cards in then in the first place.
past we stored this data in the CCB and attained the CCB via a pointer
in the SCB. In ahc_timeout(), however, the timedout SCB may have already
been completed (inherent race), meaning that the CCB could have been recycled,
and the ahc pointer reset.
Clean up the logic in ahc_search_qinfifo that deals with the busy device
table. For some reason it assumed that the only valid time to search
to see if additional lun entries should be checked was if lun 0 matched.
Now we properly itterate through the necessary luns. The busy device
table is used to detect invalid reselections, so a device would have had
to perform an unexpected reselection for this to cause problems. Further,
all luns are collapsed to a single entry unless we have external ram
with large SCBs (3940AU models) so the chance of this happening was
rather remote.
Clean up the logic for dealing with the untagged queues. We now set a
flag in the SCB that indicates that it is on the untagged queue instead
of inferring this from the type and setup of the CCB pased into us by
CAM.
In ahc_timeout(), don't print the path of the SCB until the controller
is paused and we are sure that it has not completed yet. This, in
conjunction with referencing the ahc pointer in the SCB rather than
the CCB in the SCB avoids panics in the case of a timedout scb completing
just before the timeout handler runs. This turns out to be guaranteed
if interrupt delivery is failing, as we run our interrupt handler to
flush any "just missed events" when a timeout occurs. Mention the
likelyhood of broken interrupts if a timedout SCB is completed by
our call to ahc_intr().
but pccardd apparently maps memory with MDF_16BITS flag.
So memory mapped access is disabled and use IO port instead for now.
This fixes the problem for config index 0x01 in the pccard.conf
with the message: "awi0: failed to complete selftest (timeout)"
o Remove bogus "spurious interrupt" message.
o Ring buffer head and avail were incorrectly calculated.
o Fix fragment count.
o Fix ring entry for single station, default to 16Mbit.
o Don't complain about long frames.
file types to requiring all file types to properly implement fo_stat.
This makes any new file type additions much easier as this code no
longer has to be modified to accomodate it.
o Instead of using curproc in fdesc_allocvp, pass a `struct proc' pointer as
a new fifth parameter.
a resource shortage occurs, freeze our queue and then set the resource
shortage flag while the controller data structure is locked. The old
code did these in the wrong order potentially allowing our interrupt
handler to release the queue and clear the flag before the freeze
ever occurred.
Before calling kernacc(), make sure that we're not calling it
with a K0SEG address.
This gets alphas booting with SMP_DEBUG & INVARIANTS options
