ACPI wakeup code and teach it how to start the APs again. As a side
effect the CPU_START interface allows choosing between different
bootstrap codes more easily now.
- 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.
the process page table, properly uvm_unmap1() the VA range and enter a new
uvm_map backed by an object. There is a know race between uvm_unmap1() and
uvm_map(), where another thread could get our VA range; in practice
I think none of the softwares using this interface are multithreaded (or at
last they are single-threaded when using it).
The general trend is to remove it from all kernel interfaces and
this is a start. In case the calling lwp is desired, curlwp should
be used.
quick consensus on tech-kern
argument. Use this and replace the inline assembly (mul + div using the
64bit intermediate result) with normal 32bit multiplication and
division. The compiler can turn the division into a multiplication and
shift, making it even cheaper then the original assembly. For extreme
long delays, just use 64bit arithmetic.
- reduce differences between amd64 and i386. notably, share pmap.c
between them. it makes several i386 pmap improvements available to
amd64, including tlb shootdown reduction and bug fixes from Stephan Uphoff.
- implement deferred pmap switching for amd64.
- remove LARGEPAGES option. always use large pages if available.
also, make it work on amd64.
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.
