ad | Fix false sharing problems with cpu_info. Identified with tprof(8).
This was a very nice win in my tests on a 48 CPU box.
- Reorganise cpu_data slightly according to usage.
- Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc).
- On x86, put some items in their own cache lines according to usage, like
the IPI bitmask and ci_want_resched.

ad | cpu_need_resched():
- Remove all code that should be MI, leaving the bare minimum under arch/.
- Make the required actions very explicit.
- Pass in LWP pointer for convenience.
- When a trap is required on another CPU, have the IPI set it locally.
- Expunge cpu_did_resched().

reinoud | Add preliminary KGDB support for NetBSD/usermode, currently only under amd64

reinoud | branches: 1.10.46; 1.10.48;
Fix /dev/kmem access and make vmstat(1) `work'. Not sure all the results are
indeed valid or correct but at least it shows them without coredumping or
coredumping the kernel.

reinoud | My fault, forgot that cpu_need_resched() is indeed already declared as a function
|
| 1.8 |
| 19-Jan-2012 |
reinoud | Add macro cpu_need_resched
|
| 1.7 |

reinoud | Define astpending flag and the aston() setter

jmcneill | branches: 1.6.2; 1.6.6;
- initialize cpu_info_primary early, before cpu0 attaches
- track idepth in cpu_info struct and use it in cpu_intr_p
- for debug and diagnostic kernels, abort when rebooting
- fill in __cpu_simple_lock_* stubs
- splraise(IPL_HIGH) before calling kernmain
- pmap_extract: only return phys addr if pap is not NULL

jmcneill | Clean up extern mess by adding an API for kernel components to call libc
functions. thunk.c is built with special cflags that makes it compile
against standard system headers instead of kernel ones.
|
| 1.4 |
| 11-Aug-2011 |
jmcneill | initialize lwp0 l_addr so we can switch back to it
|
| 1.3 |
| 21-Oct-2009 |
rmind | Remove uarea swap-out functionality:
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code. Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.
Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).
Discussed on <tech-kern>, reviewed by <ad>.
