H A Dbuild.sh1.373 Tue Jul 18 16:59:57 GMT 2023 lukem build.sh: use mk.conf (if present) as MAKECONF

Set MAKECONF to mk.conf in the same directory as build.sh
(i.e., the top of the source tree) if mk.conf is present.
This means unprivileged users can benefit from mk.conf(5)
semantics without write privileges to /etc/mk.conf, and
also simplifies per-source-directory configuration.

Fail early if $MAKECONF is empty, since build.sh will fail
anyway after rebuilding nbmake.

Ensure that the computed MAKECONF isn't empty, and then
always set MAKECONF in the makewrapper (nbmake-$MACHINE).

Improve some formatting consistency in BUILDING.mdoc,
(even if BUILDING is generated without markup).

H A Dpmap.c1.373 Tue Apr 23 11:21:21 GMT 2019 bouyer branches: 1.373.2;
Fix a deadlock between the pool and pmap codes:
- cpu0 grabs the kernel lock (e.g. from a non-MPSAFE interrupt) and
calls pool_get().
- cpu1 does a pool_get() on the same pool from MPSAFE code, which needs a
pool_page_alloc(), which ends up in pmap_extract_coherency().

So cpu0 holds the kernel_lock and wants the pool lock. cpu1 holds the pool
lock and wants the kernel_lock in pmap_extract_coherency().

The pmap code should not rely on kernel_lock. Intead make the
pmap_kernel()->pm_obj_lock a IPL_VM lock and use it as pmap lock
(thus dropping the pmap test pmap_{acquire,release}_pmap_lock()).
This needs to be a IPL_VM because unlike user pmaps, this can be locked
from interrupt context.

Add a IPL_NONE lock for pmap_growkernel(). We can't use
pmap_kernel()->pm_obj_lock here because pmap_grow_map() may sleep.

Make pmap_lock (which may be locked with pm_obj_lock held) a IPL_VM
lock in all case.

reorder a few things to not call pool_get()/pool_put() (which may sleep)
with pm_obj_lock held.

Patch initially posted to port-arm@ on April 19, improved patch (per
suggestions from Nick Hudson and Jason Thorpe) on April 21.

H A Duvm_map.c1.373 Sat Mar 14 14:15:43 GMT 2020 ad - uvmspace_exec(), uvmspace_free(): if pmap_remove_all() returns true the
pmap is emptied. Pass UVM_FLAG_VAONLY when clearing out the map and avoid
needless extra work to tear down each mapping individually.

- uvm_map_lookup_entry(): remove the code to do a linear scan of map entries
for small maps, in preference to using the RB tree. It's questionable,
and I think the code is almost never triggered because the average number
of map entries has probably exceeded the hard-coded threshold for quite
some time.

- vm_map_entry: get it aligned on a cacheline boundary, and cluster fields
used during rbtree lookup at the beginning.

H A Dkern_sig.c1.373 Tue Oct 15 13:59:57 GMT 2019 kamil Remove the short-circuit lwp_exit() path from sigswitch()

sigswitch() can be called from exit1() through:

ttywait()->ttysleep()-> cv_timedwait_sig()->sleepq_block()->issignal()->sigswitch()

lwp_exit() called for the last LWP triggers exit1() and this causes a panic.

The debugger related signals have short-circuit demise paths in
eventswitch() and other functions, before calling sigswitch().

This change restores the original behavior, but there is an open question
whether the kernel crash is a red herring of misbehavior of ttywait().

This should fix PR kern/54618 by David H. Gutteridge

definitions match those of i386.
Mostly just structure and field renames, in addition:
1) process_xmm_to_s87() and process_s87_to_xmm() moved into
x86/convert_xmm_s87.c so they can be used by amd64's netbsd32 code.
2) The linux signal code simplified to use a structure copy for ths fxsave
data - it matches the hardware definition and won't change.

H A Dmachdep.c1.373 Mon Mar 17 11:39:02 GMT 2025 riastradh x86: Set tf_trapno = T_ASTFLT on exec.

In most cases, the caller will already have tf_trapno=T_ASTFLT and
tf_err=2 -- the latter being the size of the SYSCALL instruction for
ERESTART handling. ERESTART handling is not relevant after exec, but
checking for AST on userret may be.

Hoping this will fix the i386 test bed! Aside from padding fields,
these (tf_trapno and tf_err) are the only two members of trapframe
that were newly zeroed on i386. The corresponding amd64 changes --
which zeroed many other registers -- worked in my testing, but
evidently that wasn't enough testing.
