phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:
1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.
2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.
I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
passed from the firmware, so change root file system type from
explicit nfs to generic '?' so that the INSTALL kernel can also be used
as a rescue kernel on localdisk.
mips struct cpu_info and related macroes.
The member was prepared for a hack in MD microtime(9) implementation
but it has been superseded by MI timecounter(9).
each icu irq to support multi function PCI devices in the Qube's PCI slot:
- split out interrupt stuff from machdep.c into new interrupt.c
- prepare struct *_intrhead to handle cpu and icu interrupts
- use LIST and malloc(9) to handle multiple interrupts per icu irq
(mostly taken from algor/pci/pcib.c and evbmips/malta/pci/pcib.c)
- move evcnt(9) stuff into *_intrhead from cobalt_intrhand
(i.e. make it per interrupt rather than per handler)
- in pci_intr_map(9) handle CPU interrupt separately and add a sanity check
- fixup interrupt lines for devices on the PCI slot in pci_conf_interrupt(9)
- move some device address definitions into <machine/cpu.h> and
remove <machine/leds.h>
- misc cosmetics
No objection on port-cobalt for three weeks.
Don't enable unhandled interrupts before all interrupts are processed.
Should fix "long download, network frozen" problems reported on
port-cobalt by several people.
print "NetBSD/cobalt Shutting donw..." on halt via shutdown hook.
This would be useful for users who don't have serial console.
No objection on port-cobalt.
- prepare two TX descriptors to avoid race and also use chaind mode
- use a recently added pcicfgread() function to get tulip I/O address
- use cobalt model id to see if we have 21041 or 21143
(XXX maybe it's better to see PCI product ID)
- add code to reset SIA on 21041
- prepare and send filter setup packet on init
- reduce delay in RX polling
- bump version again
Now netboot works fine on Qube 2700 (even without console). Yay.
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.
Proposed on: <tech-kern>
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.
is already in use and just return NULL instead.
Such situation could happen with devices which have
unconfigured PCI interrupt pins (because firmware
doesn't configure multiple function devices) and
each driver could handle the return value properly.
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
SEMMNI, SEMMNS, SEMUME and SHMMAXPGS.
They can be tweaked via sysctl now. Ports that were setting values on
them weren't touched, I only removed the ones that were commented out.
to avoid possible race condition between CPU writeback vs DMA write
- remove unnecessary FS and LS bits from RxD->xd0
(sys/dev/ic/tulipvar.h sets them but maybe they are ignored?)
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.
Fixes silent hangs after loading 4.0_BETA2 GENERIC kernel
on Qube2 (and RaQ2) with 256MB RAM, reported and tested
by James Hartley on port-cobalt.
Obviously this should be pulled up to netbsd-4.
by our native bootloader.
- Restore lwp0.l_cpu (which is required for curcpu()) and
cpu_info_store.ci_curlwp after clearing BSS in case
a kernel is loaded by the firmware directly since these
values are in BSS and initilized before mach_init() is called.
(actually they are restored in mips_machdep.c:mips_vector_init()
but we use curcpu() earlier than that point)
Fixes silent hang right after boot on cobalt.
from doc/BRANCHES:
idle lwp, and some changes depending on it.
1. separate context switching and thread scheduling.
(cf. gmcgarry_ctxsw)
2. implement idle lwp.
3. clean up related MD/MI interfaces.
4. make scheduler(s) modular.
