- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.
This address kern/18407
useful. The functions delay, cpu_initclocks, and setstatclcokrate have been
renamed to mips3_delay, mips3_initclocks, and mips3_setstatclockrate.
We provide weak aliases for the original names, so machdep code doesn't have
to provide wrapper routines. (Giving good performance.)
I've moved mips3_clockintr, mips3_initclocks, and mips3_setstatclockrate to
their own mips3_clockintr file, because some ports may not be able to use
these, and its senseless to carry that baggage.
Convert to timecounters.
From Rivo Nurges (rix at estpak dot ee). ok soren@, tested by simon@.
Note that this means we aren't using the gt clock, and maybe we should clean
that up a bit.

# XXX Disable zero-copy page loaning in sosend() temporarily:
# PV mappings created by sosend_loan() in sys/kern/uipc_socket.c may
# produce virtual cache aliases and it seems to cause TLB MISS panic
# in cache flush code called from bus_dmamap_sync(9) PREWRITE ops
# during heavy TX packet traffic on tlp(4).
works properly
(XXX: the real fix is to implement proper CLFK_BASEPRI())
- prepare an independent statclock(9) handler which use MIPS3 CPU internal
clock interrupt. Enabled by options ENABLE_INT5_STATCLOCK, but not enabled
by default.
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.
Approved by core@. Fixes PR port-evbmips/32362.
- move ICU interrupt stuff from pci/pcib.h to cobalt/machdep.c
because ICU should be initialized before pcib is attached
- initialize ICU more properly
- check interrupt types and set ELCR (edge/level control registers)
accordingly in icu_intr_establish()
- check requested IRQ line and call only a necessary hander in icu_intr()
- use specific EOI to ack interrupts rather than AEOI
- use macro defined in <dev/ic/i8259reg.h>
