and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)
XPMSG_DEMAP_TLB_REGION, XPMSG_DEMAP_TLB_CONTEXT and XPMSG_DEMAP_TLB_ALL
- new setpgt4m_va(), call it when you need to ensure all cpus see the same value
- new smp_tlb_flush_context(), smp_tlb_flush_region(), smp_tlb_flush_segment(),
smp_tlb_flush_page() and smp_tlb_flush_all() functions, if MULTIPROCESSOR
- define the tlb_flush*() routines to the smp_*() versions, if MULTIPROCESSOR
- sun4m safe PTE update updatepte4m() routine, vaguely derived from code posted
by torek@bsdi.com on port-sparc a couple of years ago.
- new nmihard_lock to synchronize other cpus during hard NMI. (XXX: should be
a bit smarter about which CPU's do/don't check in.)
occured. cpus now spin waiting for new `go_smp_cpus' variable to go non-zero.
- new xpmsg_lock that must held around all cross call activity. new macros:
LOCK_XPMSG() and UNLOCK_XPMSG().
- delete delay(1)/cache_flush gone from raise_ipi_wait_and_unlock(), it incurred
a stupid performance penalty.
option for System V semaphores. It appears that there are no overrides
in the code and each file has the following added.
options SYSVSEM # System V semaphores
+#options SEMMNI=10 # number of semaphore identifiers
+#options SEMMNS=60 # number of semaphores in system
+#options SEMUME=10 # max number of undo entries per process
+#options SEMMNU=30 # number of undo structures in system
options SYSVSHM # System V shared memory
If anyone thinks that this is incorrect for any of these files, please
correct it.
Note - the i386 port was not forgotten. It was done separately.
of the code expects zero. Add some wrappers so that opf promops are
consistent with obp promops. Now microSPARC-IIep correctly panics ;)
While here, propagate 'static' to opf_* definitions.
and prom version. Little tweaks to prom during secondary boot are
much easier then fragile work-arounds in the kernel. Currently this
is used for JavaStation 1 with OBP3.
