Arrange to update cached LWP credentials in userret() rather than during syscall/trap entry, eliminating a test+branch on every syscall/trap.
This wasn't possible in the 3.99.x timeframe when l->l_cred came about because there wasn't a reliable/timely way to force an ONPROC LWP running on a remote CPU into the kernel (which is just about the only new thing in this scheme).

Improve KGDB enabled build for news68k: * include sys/kgdb.h in news68k/trap.c for missing definitions. * cast second kgdb_trap argument to (db_regs_t *). * build m68k/kgdb_machdep.c for kgdb_trap() implementation.
Same as for mvme68k, build complains about undefined reference to zs_check_kgdb due to missing port specific zs kgdb implementation for MI zs(4) driver though.

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.
Welcome to NetBSD 8.99.37.

Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port.
Tested by rjs@ on a Quadra 950. (Thanks!)

Merge the ppcoea-renovation branch to HEAD.
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.

branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.

merge the 12 copies of vm_machdep.c on the m68k platforms. clean up some other stuff along the way, including: - use m68k/cacheops.*, remove duplicates from cpu.h. - centralize a few declarations in (all the copies of) cpu.h. - define M68K_VAC on platforms which have a VAC. - switch the sun platforms to the (now common) proc_trampoline(). - do the phys_map thang on the sun platforms too, no reason not to.

branches: 1.19.4; Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.

Sprinkle pmap_update() calls after calls to: - pmap_enter() - pmap_remove() - pmap_protect() - pmap_kenter_pa() - pmap_kremove() as described in pmap(9).
These calls are relatively conservative. It may be possible to optimize these a little more.

branches: 1.4.2; Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Arrange to update cached LWP credentials in userret() rather than during syscall/trap entry, eliminating a test+branch on every syscall/trap.
This wasn't possible in the 3.99.x timeframe when l->l_cred came about because there wasn't a reliable/timely way to force an ONPROC LWP running on a remote CPU into the kernel (which is just about the only new thing in this scheme).

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.
Welcome to NetBSD 8.99.37.

Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port.

Merge the ppcoea-renovation branch to HEAD.
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.

branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.

Sprinkle pmap_update() calls after calls to: - pmap_enter() - pmap_remove() - pmap_protect() - pmap_kenter_pa() - pmap_kremove() as described in pmap(9).
These calls are relatively conservative. It may be possible to optimize these a little more.

branches: 1.4.2; Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.

Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port.

Merge the ppcoea-renovation branch to HEAD.
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.

branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.

branches: 1.4.2; Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.
Welcome to NetBSD 8.99.37.

Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port.
Tested by rjs@ on a Quadra 950. (Thanks!)

Merge the ppcoea-renovation branch to HEAD.
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.

branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.

merge the 12 copies of vm_machdep.c on the m68k platforms. clean up some other stuff along the way, including: - use m68k/cacheops.*, remove duplicates from cpu.h. - centralize a few declarations in (all the copies of) cpu.h. - define M68K_VAC on platforms which have a VAC. - switch the sun platforms to the (now common) proc_trampoline(). - do the phys_map thang on the sun platforms too, no reason not to.

branches: 1.19.4; Update pmap_update to now take the updated pmap as an argument. This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.

Sprinkle pmap_update() calls after calls to: - pmap_enter() - pmap_remove() - pmap_protect() - pmap_kenter_pa() - pmap_kremove() as described in pmap(9).
These calls are relatively conservative. It may be possible to optimize these a little more.

branches: 1.4.2; Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.

Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port.

Merge the ppcoea-renovation branch to HEAD.
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.

mhitch |
branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.

branches: 1.4.2; Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.
Welcome to NetBSD 8.99.37.

Refactor the 68040 writeback() from each m68k port's trap handler into a shared copy: m68040_writeback(). It is essentially a copy of the Atari version, with some minor cosmetic tweaks and one small performance optimization from the mvme68k port.

Merge the ppcoea-renovation branch to HEAD.
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.

branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.

- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Overhaul the API used to fetch and store individual memory cells in userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(), subyte(), suword(), etc.) are retired and replaced with new ufetch(9) and ustore(9) APIs that can return proper error codes, etc. and are implemented consistently across all platforms. The interrupt-safe variants are no longer supported (and several of the existing attempts at fuswintr(), etc. were buggy and not actually interrupt-safe).
Also augmement the ucas(9) API, making it consistently available on all plaforms, supporting uniprocessor and multiprocessor systems, even those that do not have CAS or LL/SC primitives.

Merge the ppcoea-renovation branch to HEAD.
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.

branches: 1.54.4; 68030 and 68040 processors consider the read portion of a read-modify-write transfer as a write to ensure the memory is writable before starting any transfer. The fault status information does not reflect this in the 'read' status bit (i.e. it shows up as a read access), so faults with a RMW access to non-writable memory was not getting the correct protection. The page would be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts to execute a RMW access to a data page, which is read-only because it's CoP Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write fault bits, and both are set on a RMW access and the trap code was checking the write status bit.
Fixes PR#36848.

* Shuffle some data structures so, and add a flags word to ksiginfo_t. Right now the only flag is used to indicate if a ksiginfo_t is a result of a trap. Add a predicate macro to test for this flag. * Add initialization macros for ksiginfo_t's. * Add accssor macro for ksi_trap. Expands to 0 if the ksiginfo_t was not the result of a trap. This matches the sigcontext trapcode semantics. * In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal. Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles the case of non-trap-generated signals that have a > 0 si_code.
This patch fixes a signal delivery problem with threaded programs noted by Matthias Drochner on tech-kern.
As discussed on tech-kern. Reviewed and OK's by Christos.

branches: 1.4.2; Reduce use of curproc in several places:
- Change ktrace interface to pass in the current process, rather than p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it handy anyway.
- Add a second proc argument for inferior() since callers all had curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O (simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD. Do non-blocking I/O, and yield a finite number of times when receiving EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()

First sweep at scheduler state cleanup. Collect MI scheduler state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap of non-empty run queues), sched_slpque (sleep queues). NOTE: These may collectively move into a struct schedstate at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime (time process on this CPU started running), spc_flags (replaces struct proc's p_schedflags), and spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and a curcpu() macro. Simplify existing cpu_info declarations where appropriate.
- All references to per-CPU scheduler state now made through curcpu(). NOTE: this will likely be adjusted in the future after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies in advance if it doesn't compile on a particular platform.

Use preempt(), not an open-coded equivalent (which won't be equivalent for long).
