Fix so that resource wait queueing works.
Changed all functions to take a pointer to uba_softc instead of unit
number, except for ubareset(). This must be done later.
profiling enabled. (named the same as what GENERIC kernel
would be named if configured with config -p, which would end up
generating the same kernel as this.)
figure out the correct IRQ for the ethernet on the AlphaStation 500.
That code is enabled via KN20AA_BOGUS_IRQ_FROB (but hopefully won't be
needed any time soon, and won't link w/o slight changes to other code).
Basically, when establishing an interrupt that we don't know what to
do with, prompt the user for what interrupt line to enable. If you
get stray interrupts when you try to use the device (but not before),
then you've got the right line.
found on the AlphaStation 600), and interrupts on interrupt line 13.
Thanks to Andrew Gallatin for booting a test kernel 32 times (trying
each interrupt line, looking for the right one) to find this.
programs which attach their own header) can crash the machine. The problem
in this case was:
a variable "space" was set to the total data to copy,
len was used to remember how much to copy in this chunk (mbuf),
in one case, len = min(MCLBYTES - max_hdr, resid) but
size -= MCLBYTES;
instead of
size -= len;
Note that userland programs can still crash the machine by providing
bogus data in the ip->ip_len field I suspect. I haven't verified this,
but will soon be doing so and applying a fix of some sort. Probably
clamping the ip->ip_len value to the true packet size will be ok.
definitions.
* Include <mips/cpuregs.h> in <cpu.h> so kern_clock.c has user/kernel
status bits in scope. Still needs work; r2k/r4k previous-mode bits
are different.
* Include <mips/mips_param.h> in pica/include/param.h, for locore declarations,
and definitions of vm and other constants that should be shared across
NetBSD/mips systems to esnsure user-level binary compatibility.
* include <mips/locore.h> where callbacks into locore are made, to get
prototypes in scope. Cast calls appropriately.
* include <mips/cpuregs.h>, not the old Sprite-derived <machine/machConst.h>.
machConst.h is deprecated.
* dk_establish() must return void, not int.
