Based on PR port-powerpc/40421 from Wojciech Galazka,
with misc tweaks by me.
Note sysinst part is not pulled because there is
no supported storage device yet on this port.
This is a port of the OpenBSD pmap and trap handling code to get us
- Performance boost on some/all machines.
- Well on the way to PA2.0 (in 32bit mode) support. Several
machines probe hardware, but fail sometime after interrupts
are enabled.
Other things changed / fixed on the branch are
- update autoconf to use the OpenBSD code.
- com @ dino is very close to being supported.
- HPPA_REDZONE has been replaced with a working redzone which
is enabled with DIAGNOSTIC.
- UPAGES has been halved in size.
- power(4) from OpenBSD to fix a few bugs.
- updated list of modules from OpenBSD.
- initial ports of uturn(4), astro(4) and elroy(4).
- update some copyrights (remove advertising clause, etc.)
Thanks to mjf for some of the above, testing and listening.
Do some manual post-processing and use that as new gcc(1).
The original version is included to add as base for three-way merges.
OK wiz, no objection from tech-userlevel.
Don't try to unregister the watchdog in elansc_detach() if we are
shutting the system down, because unregistering is designed to fail if
the watchdog is armed.
kernels running in other processes on the same machine or on an
entirely different host. I wrote this a while ago and am now
committing it mainly to avoid losing it. It works, but could do
with a little tuning here and there.
What this will hopefully eventually buy us is the ability to use
standard userland tools to configure rump kernels, e.g. ifconfig(8)
and route(8) could be used to configure the networking stack provided
by a rump kernel. Also some distributed OS implications may apply.
fun fact: a system call which just does copyin/copyout takes >1000x
longer when made over the LAN as compared to when made on the same
machine.
lookups through them. This has two implications:
1) mountpoints can be created directly onto the rump rootfs.
this is benefitial in test programs where we want the same
program to be easily switched between testing against rump and
testing against the host kernel.
2) fakeblk must be used (it used to work implicitly) to register
block devices that should be used from the host fs namespace.
- pull MACSTAT and CMDSTOP quirks for 8168/8111 chips
- always set CPLUSCMD_PCI_MRW on reset
- set VLANSTRIP and RXCSUM_ENB bits on CPLUS register per if_capenable
Tested on 8111C and 8111D by several users, and
no bad side effect on my old 8169S.
a new struct mount-allocation routine, vfs_mountalloc(9). Documentation
updates will follow.
Attention: Synchronization Oversight Committee! In mount_domount(),
I postpone the call mutex_enter(&mp->mnt_updating) until right before
the VFS_MOUNT(9) call because (1) that looks to me like the earliest
possible opportunity for mp to become visible to any other LWP, because
it was just kmem_zalloc(9)'d and (2) it made extracting the common code
much easier. Tell me if my reasoning is faulty.
