PVH and HVM guests can easily have more than XEN_LEGACY_MAX_VCPUS (32) cpus. Support up to HVM_MAX_VCPUS (256). This requires resizing a few arrays in evtchn.c, and using VCPUOP_register_vcpu_info for vcpuid >= XEN_LEGACY_MAX_VCPUS Tested with 96 vCPUs.

Some devices (e.g. ixg in MSI-X mode) don't to have their handlers called when no interrupt are pending. So add an extra ih_pending field to struct intrhand, which is incremeted when the handler is not called because of IPL level and reset to 0 when called. Check this in Xen's resume assembly to call only handlers that are really pending.

Change event_set_handler() to take the target CPU parameter. If ci is NULL, event_set_handler() will choose the CPU and bind the event. If ci is not NULL the caller is responsible for binding the event. Use a IPI xcall to register the handlers if needed. pull in a hack from x86 to force pirq handlers to be mpsafe if registered at a level != IPL_VM. This is for the com at isa interrupt handler, which registers at IPL_HIGH and has to way to tell it's mpsafe (taking KERNEL_LOCK at IPL_HIGH causes deadlocks on MP systems).

Add PVHVM multiprocessor support: We need the hypervisor to be set up before cpus attaches. Move hypervisor setup to a new function xen_hvm_init(), called at the beggining of mainbus_attach(). This function searches the cfdata[] array to see if the hypervisor device is enabled (so you can disable PV support with disable hypervisor from userconf). For HVM, ci_cpuid doens't match the virtual CPU index needed by Xen. Introduce ci_vcpuid to cpu_info. Introduce xen_hvm_init_cpu(), to be called for each CPU in in its context, which initialize ci_vcpuid and ci_vcpu, and setup the event callback. Change Xen code to use ci_vcpuid. Do not call lapic_calibrate_timer() for VM_GUEST_XENPVHVM, we will use Xen timers. Don't call lapic_initclocks() from cpu_hatch(); instead set x86_cpu_initclock_func to lapic_initclocks() in lapic_calibrate_timer(), and call *(x86_cpu_initclock_func)() from cpu_hatch(). Also call x86_cpu_initclock_func from cpu_attach() for the boot CPU. As x86_cpu_initclock_func is called for all CPUs, x86_initclock_func can be a NOP for lapic timer. Reorganize Xen code for x86_initclock_func/x86_cpu_initclock_func. Move x86_cpu_idle_xen() to hypervisor_machdep.c

By default, events are bound to CPU 0 (exept for IPIs and VTIMERs which are bound to a different CPU at creation time). Recent MI changes caused the scheduler to choose a different CPU when probing and attaching xennet devices (I guess it's the xenbus thread which runs on a different CPU). This cause the callback to be called on a different CPU than the one expected by the kernel, and the event is ignored. It is handled when the clock causes the callback to be called on the right CPU, which is why xennet still run, but slowly. Change event_set_handler() to do a EVTCHNOP_bind_vcpu if requested to, and make sure we don't do it for IPIs and VIRQs (for theses, the op fails).

Excise XEN specific code out of x86/x86/intr.c into xen/x86/xen_intr.c While at it, separate the source function tracking so that the interrupt paths are truly independant. Use weak symbol exporting to provision for future PVHVM co-existence of both files, but with independant paths. Introduce assembler code such that in a unified scenario, native interrupts get first priority in spllower(), followed by XEN event callbacks. IPL management and semantics are unchanged - native handlers and xen callbacks are expected to maintain their ipl related semantics. In summary, after this commit, native and XEN now have completely unrelated interrupt handling mechanisms, including intr_establish_xname() and assembler stubs and intr handler management. Happy Christmas!

add support for kern.intr.list aka intrctl(8) 'list' for xen event_set_handler() and pirq_establish() now have extra intrname parameter; shared intr_create_intrid() is used to provide the value xen drivers were changed to pass the specific driver instance name as the xname, e.g. 'vcpu0 clock' instead just 'clock', or 'xencons0' instead of 'xencons' associated evcnt is now changed to use intrname - this matches native x86

Fixes for physical interrupts on Xen: - do not cast int * to intr_handle_t *, they're not the same size - legacy_irq is not always -1 for ioapic interrupts, test pic_type instead - change irq2port[] to hold (port + 1) so that 0 is an invalid value - add KASSERTs to make sure vect, port or irq values extracted from arrays are valid (or that they are invalid before write) - for the !ioapic case, we still need to do PHYSDEVOP_ASSIGN_VECTOR and bind_pirq_to_evtch(). now XEN3_DOM0 boots again

Back out previous KASSERTMSG for now. The immediate problem appears to have been elsewhere, in the wrong interrupt level passed by the Xen-specific intr_establish to event_set_handler. We should maybe restore these assertions later, but at least one was violated before cherry's interrupt rototill anyway.

Fix theoretical race in xen_evtchn_trymask.
This now matches ioapic_trymask:
- Caller masks CPU interrupts while the PIC's interrupts are unmasked.
- Trymask masks the PIC's interrupts, and tests whether any were
pending that we missed because the CPU interrupts are masked.
==> If there were any pending, trymask unmasks PIC's interrupts and
returns false.
==> If not, interrupts are masked on the PIC and CPU and there were
none pending and trymask returns true.
No functional change right now because cpu_intr_redistribute is
currently disabled on Xen.
ok cherry

With help from Robert Elz we've finally figured out what's going on, and it actually isn't a bug in the handler, but related to spin mutexes. When a spin mutex is released, the IPL isn't lowered back if the curcpu is holding other spin mutexes. This is because mutexes may not be released in order (and, in this case, the CPU in interrupted while it holds a spin mutex at IPL < IPL_SCHED). Also remove the test and resetting the IPL, it will be reset anyway inside the loop, or at the end of the loop.

Simplify the xen event handler callback by: - moving the interrupt handler callback traversal into a separate function. - using evt_iterate_bits() to scan through the pending bitfield - removing cross-cpu pending actions - events recieved on the wrong vcpu are re-routed via hypervisor_send_event(). - simplifying nested while() loops by encapsulating them in equivalent functions. Many thanks for multiple reviews by bouyer@ and jym@

Do not escalate the local spl while taking the interrupt handler list lock. Re-entrance is protected against within the events handler framework by toggling interrupts/events, so we don't need (and cannot use) the spl framework in that path. The other consumers (interrupt registration/removal code) are not spl sensitive wrt this lock.

hypervisor_set_ipending() should not set the pending flag across cpus. The reason for this is that the pending flag update is not atomic, or protected by a lock. Since its current (mis)use in evtchn_do_event() across cpus is to notify the remote cpu of an interrupt, we use hypervisor_send_event() instead, to trigger an event on the remote cpu, which in turn invokes evtchn_do_event() on that cpu and DTRT on it. On the local cpu, we protect hypervisor_set_ipending() from re-entry via cli(). Remove a redundant and unprotected call to hypervisor_set_ipending(). Thanks to jym@ for spotting this discrepancy while reviewing a related patch. See: http://mail-index.netbsd.org/tech-kern/2012/11/12/msg014374.html

Xen MP merge introduced MP safety around ipl handlers. When removing an event handler, check handler's function and arguments against the real ones, not the ones from wrappers. This fixes a bug where !mpsafe events could not be removed from the handler chain, thereby blocking suspension of a domU. ok releng@.

Merge jym-xensuspend branch in -current. ok bouyer@. Goal: save/restore support in NetBSD domUs, for i386, i386 PAE and amd64. Executive summary: - split all Xen drivers (xenbus(4), grant tables, xbd(4), xennet(4)) in two parts: suspend and resume, and hook them to pmf(9). - modify pmap so that Xen hypervisor does not cry out loud in case it finds "unexpected" recursive memory mappings - provide a sysctl(7), machdep.xen.suspend, to command suspend from userland via powerd(8). Note: a suspend can only be handled correctly when dom0 requested it, so provide a mechanism that will prevent kernel to blindly validate user's commands The code is still in experimental state, use at your own risk: restore can corrupt backend communications rings; this can completely thrash dom0 as it will loop at a high interrupt level trying to honor all domU requests. XXX PAE suspend does not work in amd64 currently, due to (yet again!) page validation issues with hypervisor. Will fix. XXX secondary CPUs are not suspended, I will write the handlers in sync with cherry's Xen MP work. Tested under i386 and amd64, bear in mind ring corruption though. No build break expected, GENERICs and XEN* kernels should be fine. ./build.sh distribution still running. In any case: sorry if it does break for you, contact me directly for reports.

VIRQ_TIMER virqs are allocated and tracked in a array (virq_timer_to_evtch, indexed by cpuid) different from the VIRQ <> event channel one (virq_to_evtch, indexed by event channel ID). This is fine: fix a "harmless" bug that resulted in the event channel of VIRQ_TIMER getting lost during bind as it was not stored in the proper array. "Harmless" because it is not critical for -current, however in the Xen save/restore branch this completely cripples restore. Xen clock gets suspended, but never comes back (fetched channel ID being invalid). Oops. Add a small comment so we can better see the "get => allocate? => set" chain of actions when binding/unbinding event channels.

- Upgrade suspend/resume code to comply with Xen2 removal. - Add support for PAE domUs suspend/resume. - Fix an issue regarding initialization of the xbd ring I/O that could end badly during resume, with invalid block operations submitted to dom0 backend. NetBSD supports PAE under x86_32 by considering the L2 page as being 4 pages long instead of 1. Xen validates the page types during resume. Sadly, the hypervisor handles alternative recursive mappings (== PG/PD entries pointing to pages other than self) inadequately, which could lead to incorrect page pinning. As a result, the important change with this patch is to clear these alternative mappings during suspend, and reset them back to their former self upon resume. For PAE, approx. all 4 PDIR_SLOT_PTEs could be considered as alternative recursive mappings. See comments in pmap.c for further details. Now, let the testing and bug hunting begin.

Modifications for the Xen suspend/migrate/resume branch:
- introduce xenbus_device_{suspend,resume}() functions. These are routines
used to suspend/resume MI parts of the Xenbus device interfaces, like updating
frontend/backend devices' paths found in XenStore.
- introduce HYPERVISOR_sysctl(), an hypercall used only by Xentools to obtain
information from hypervisor (listing VMs, printing console, etc.). I use it
to query xenconsole from ddb(), as a last resort in case of a panic() in
dom0 (xm being not available). Currently unused in the branch; could be, if
requested.
- disable the rwlock(9) used to protect code that could use transient MFNs.
It could trigger nasty context switches in place it should not to.
- fix some bugs in the xennet/xbd suspend/resume pmf(9) handlers.
- following XenSource's design, talk_to_otherend() is now called
watch_otherend(), and free_otherend_details() is used by Xenbus device
suspend/resume routines.
- some slight modifications in pmap regarding APDP. Introduce an inline
function (pmap_unmap_apdp_pde()) that clears APDP entry for the current pmap.
- similarly, implement pmap_unmap_all_apdp_pdes() that iterates through all
pmaps and tears down APDP, as Xen does not handle them properly.
TODO/XXX:
- pmap_unmap_apdp_pde() does not handle APDP shadow entry of PAE. It will,
once I figure out how PAE uses it.
- revisit the pmap locking issue regarding transient MFNs. As NetBSD does not
use kernel preemption and MP for Xen, this could be skipped momentarily. See
http://mail-index.netbsd.org/port-xen/2009/04/27/msg004903.html for details.
- fix a bug regarding grant tables which could technically DoS a dom0 if
ridiculously high consumer/producer indexes are passed down in the ring during
a resume.
All in all, once the grant table index issue and APDP PAE are fixed, next step
is to torture test this branch.
Tested under i386 PAE and non-PAE, Xen3 dom0 and domU. amd64 is only compile
tested.

Initial code for xen save/restore/migrate facilities.
- split the attach code of frontends in two half: one that is only needed
during autoconf(9) attach/detach phases, and one used at each save/restore
of device state (between suspend and resume).
Applies to hypervisor, xencons, xenbus, xbd, and xennet.
- add a rwlock(9) ("ptom_lock") to protect the different parts in the kernel
that manipulate MFNs (which could change between a suspend and a resume,
without the kernel noticing it). Parts that require MFNs acquire a reader lock,
while suspend code will acquire a writer lock to ensure that no-other parts
in kernel still use MFNs.
- integrate the suspend code with sysmon.
- various things in pmap(9), and clock.
TODO:
- factorize code a bit more inside frontends drivers.
- remove all alternative recursive (APDP_PDE) mappings found in PD/PT during
suspend, as Xen does not support them.
- abstract the ptom_lock locking, it is only required when kernel preemption
is enabled, or on MP systems.
Current code works mostly. You may experience difficulties in some corner
cases (dom0 warnings about xennet interface errors, and Xen tools failing to
validate NetBSD's alternative pmaps).

- rename init_events() to events_init(), to better reflect netbsd semantics - change unbind_[pv]irq_from_evtch() so that they now return the event channel the [PV]IRQ was bound to. It reflects the opposite behaviour of the bind_[pv]irq_to_evtch() functions. - remove xenbus_suspend() and xenbus_resume() prototypes, as they are not used anywhere else, and will conflict with the xenbus pmf(9) handlers. - make start_info aligned on a page boundary, as Xen expects it to be so. - mask event channel during xbd detach before removing its handler (can avoid spurious events). - add the "protocol" entry in xenstore during xbd initialization. Normally created during domU's boot by xentools, it is under domU's responsibility in all other cases (save/restore, hot plugging, etc.). - modifications to xs_init(), so that it can properly return an error. Reviewed by Christoph (cegger@).

Remork the C implementation of spllower() in evtchn_do_event(), so that callbacks are always called in decreasing IPL order. Although it's not strictly a bug, it makes the code easier to read, and avoids processing the whole IPL range several times.

Implement a C version of splx() in evtchn_do_event(). using plain splx() here will reenable interrupts as a side effect, and we don't want it here. It could cause some event handlers to run twice (which should be harmless), and trap() to be called on the wrong LWP in doreti_checkast (which can probably cause some damage).

The event bitmasks provided by the hypervisor are unsigned long (so 64bits on amd64). Make sure to use the right type to store and manipulate them. This fixes amd64, where basically any event channel > 31 was not working (and you get there after starting/stopping a domU a few times). Things would occasionally unwedge though the spllower() callbacks.

Prepare for xenamd64: - kill xen/i386/identcpu.c, use i386/i386/identcpu.c instead (with a few #ifndef XEN) - move some files that can be shared between i386 and amd64 from xen/i386 to xen/x86 (or to xen/xen for non-cpu-specific code) - split assembly out of xen/include/hypervisor.h to xen/include/hypercalls.h - use <xen/...> instead of <machine/...> for cpu-independant include files. more work needed here, i386-specific files should got out of arch/xen to arch/xeni386, and more code shared with arch/i386.

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.

x86 changes for pcc and LKMs. - Replace most inline assembly with proper functions. As a side effect this reduces the size of amd64 GENERIC by about 120kB, and i386 by a smaller amount. Nearly all of the inlines did something slow, or something that does not need to be fast. - Make curcpu() and curlwp functions proper, unless __GNUC__ && _KERNEL. In that case make them inlines. Makes curlwp LKM and preemption safe. - Make bus_space and bus_dma more LKM friendly. - Share a few more files between the ports. - Other minor changes.

Add Xen3 support for ACPI and/or MPBIOS + IOAPIC. To help with this, physical CPUs are now configured on mainbus only in dom0, and only to know about their APIC id. virtual CPUs are attached to hypervisor as: vcpu* at hypervisor? and this is what's used as curcpu(). The kernel config files needs to be updated for this, see XEN3_DOM0 or XEN3_DOMU for examples. XEN3_DOM0 now has acpi, MPBIOS and ioapic by default. Note that a Xen dom0 kernel doens't have access to the lapic.

Apply patch (requested by bouyer in ticket #1245): Pull up Xen3 domU support. This adds support for the Xen-3 memory bootstrap, xenstore, and block and network device frontend. Xen-3 support is turned on by 'options XEN3', which disable Xen-2 support. Changes affecting non-xen3 specific code: - xbd and xennet at hypervisor now attaches with xbd_hypervisor and xennet_hypervisor - x86_atomic_* renamed to xen_atomic_* - use genassim.cf to pull in more constant from include files for assembly - Map the shared info page from locore.S instead of the 0xffffffff hack in xen_machdep.c - remove some unused code - some __asm__ __volatile__ -> __asm volatile and __inline__ -> inline - more debug code

Snapshot of work in progress on NetBSD port to Xen3: - kernel (both dom0 and domU) boot, console is functionnal and it can starts software from a ramdisk - there is no driver front-end expect console for domU yet. - dom0 can probe devices and ex(4) work when Xen3 is booted without acpi and apic support. But the on-board IDE doens't get interrupts. The PCI code still needs work (it's hardcoded to mode 1). Some of this code should be shared with ../x86 The physical insterrupt code needs to get MPBIOS and ACPI support, and do interrupt routing to properly interract with Xen. To enable Xen-3.0 support, add options XEN3 to your kernel config file (this will disable Xen2 support) Changes affecting Xen-2.0 support (no functionnal changes intended): - get more constants from genassym for assembly code - remove some unneeded registers move from start() - map the shared info page from start(), and remove the pte = 0xffffffff hack - vector.S: in hypervisor_callback() make sure %esi points to HYPERVISOR_shared_info before accessing the info page. Remplace some hand-written assembly with the equivalent macro defined in frameasm.h - more debug code, dissabled by default. while here added my copyright on some files I worked on in 2005.

Pull up revision 1.13 (requested by bouyer in ticket #192): Event handling optimisations: - sort the ih_evt_handler list by IPL, higher first. Otherwise some handlers would have been delayed, event if they could run at the current IPL. - As ih_evt_handler is sorted, remove IPLs that have been processed for an event when calling hypervisor_set_ipending() - In hypervisor_set_ipending(), enter the event in ipl_evt_mask only for the lowest IPL. As deffered IPLs are processed high to low, this ensure that hypervisor_enable_event() will be called only when all callbacks have been called for an event. We don't need the evtch_maskcount[] counters any more. Thanks to YAMAMOTO Takashi for ideas and feedback.

Pull up revision 1.7 (requested by bouyer in ticket #192): Allow to pass a more descriptive name to event_set_handler() (e.g. IRQ number for physical IRQ, or device name for xen device drivers). This makes systat and vmstat output more usable, especially as the channel numbers change each time a guest reboots.

Pull up revision 1.5 (requested by bouyer in ticket #192): Get rid of the event to pseudo-irq mapping. We are limited to 32 pseudo-irq, including soft interrupt, and this is way too low in some use (lots of domains, or domains with lots of xennet, or even hardware with lots of devices at different interrupts). Based on idea from YAMAMOTO Takashi, keep one list of handler per-event and one per-IPL (so the same handler is now in 2 lists). In the common case were an event is received at low IPL, we can call the handlers quickly (there is usually only one handler per event, unless the event is mapped to a physical interrupt and this interrupt is shared by different devices). Deffered events and software interrupts are handled by a bitmask (as before) with one bit per IPL. When one IPL has an event pending all handlers for this IPL will be called. With this change, it is now possible to have all the 1024 events active. While here, handle debug event in a special way: the handler is always called, regardless of the current IPL. Make the handler print usefull informations about events and IPL states. Also remove code not used on Xen in files inherited from the x86 port.

Event handling optimisations: - sort the ih_evt_handler list by IPL, higher first. Otherwise some handlers would have been delayed, event if they could run at the current IPL. - As ih_evt_handler is sorted, remove IPLs that have been processed for an event when calling hypervisor_set_ipending() - In hypervisor_set_ipending(), enter the event in ipl_evt_mask only for the lowest IPL. As deffered IPLs are processed high to low, this ensure that hypervisor_enable_event() will be called only when all callbacks have been called for an event. We don't need the evtch_maskcount[] counters any more. Thanks to YAMAMOTO Takashi for ideas and feedback.

Avoid a race between do_hypervisor_event() and stipending() that could cause an event to be both handled and marked as pending, or being marked as pending twice (triggering the diagnostic check evtch_maskcount[port] == 0 in hypervisor_set_ipending): mask and clear event by word of 32bit in do_hypervisor_event() or stipending(), instead of by indiviual bits in do_event() or xenevt_event(). In addition this is marginally more efficient.

- Add a centralised handler for physical interrupts, which will call the real handler. This is not necessery but is usefull for debug. - make irq_needs_unmask_notify[] per-IRQ, instead of per physical IRQ - use a static physdev_op_t for PHYSDEVOP_IRQ_UNMASK_NOTIFY (it never changes, so no need to allocate a new one each time) - call pirq_notify() from hypervisor_enable_irq().
