x86: Split most of pmap.h into pmap_private.h or vmparam.h.
This way pmap.h only contains the MD definition of the MI pmap(9)
API, which loads of things in the kernel rely on, so changing x86
pmap internals no longer requires recompiling the entire kernel every
time.
Callers needing these internals must now use machine/pmap_private.h.
Note: This is not x86/pmap_private.h because it contains three parts:
1. CPU-specific (different for i386/amd64) definitions used by...
2. common definitions, including Xenisms like xpmap_ptetomach,
further used by...
3. more CPU-specific inlines for pmap_pte_* operations
So {amd64,i386}/pmap_private.h defines 1, includes x86/pmap_private.h
for 2, and then defines 3. Maybe we should split that out into a new
pmap_pte.h to reduce this trouble.
No functional change intended, other than that some .c files must
include machine/pmap_private.h when previously uvm/uvm_pmap.h
polluted the namespace with pmap internals.
Note: This migrates part of i386/pmap.h into i386/vmparam.h --
specifically the parts that are needed for several constants defined
in vmparam.h:
VM_MAXUSER_ADDRESS
VM_MAX_ADDRESS
VM_MAX_KERNEL_ADDRESS
VM_MIN_KERNEL_ADDRESS
Since i386 needs PDP_SIZE in vmparam.h, I added it there on amd64
too, just to keep things parallel.

Fix fallout from previous uvm.h cleanup. - pmap(9) needs uvm/uvm_extern.h. - x86/pmap.h is not usable on its own; it is only usable if included via uvm/uvm_extern.h (-> uvm/uvm_pmap.h -> machine/pmap.h). - Make nvmm.h and nvmm_internal.h standalone.

Introduce Xen PVH support in GENERIC. This is compiled in with options XENPVHVM x86 changes: - add Xen section and xen pvh entry points to locore.S. Set vm_guest to VM_GUEST_XENPVH in this entry point. Most of the boot procedure (especially page table setup and switch to paged mode) is shared with native. - change some x86_delay() to delay_func(), which points to x86_delay() for native/HVM, and xen_delay() for PVH Xen changes: - remove Xen bits from init_x86_64_ksyms() and init386_ksyms() and move to xen_init_ksyms(), used for both PV and PVH - set ISA no-legacy-devices property for PVH - factor out code from Xen's cpu_bootconf() to xen_bootconf() in xen_machdep.c - set up a specific pvh_consinit() which starts with printk() (which uses a simple hypercall that is available early) and switch to xencons when we can use pmap_kenter_pa().

The way the xen dummy page is taken care of makes absolutely no sense at all, with magic offsets here and there in different layers of the system. It is just blind luck that everything has always worked as expected so far. Due to this wrong design we have a problem now: we allocate one physical page for lapic, and it happens to overlap with the dummy page, which causes the system to crash. Fix this by keeping the dummy va directly in a variable instead of magic offsets. The asm locore now increments the first pa to hide the dummy page to machdep and pmap.

Extend the xpmap API, as described in [1]. This change is mechanical and avoids exposing the MD phys_to_machine/machine_to_phys tables directly. Added: - xpmap_ptom handles PFN (pseudo physical) to MFN (machine frame number) translations, and is under control of the domain. - xpmap_mtop is its counterpart (MFN to PFN), and is under control of hypervisor. xpmap_ptom_map() map a pseudo-phys address to a machine address xpmap_ptom_unmap() unmap a pseudo-phys address (invalidation) xpmap_ptom_isvalid() check for pseudo-phys address validity The parameters are physical/machine addresses, like bus_dma/bus_space(9). As x86 MFNs are tracked by u_long (Xen's choice) while machine addresses can be 64 bits entities (PAE), use ptoa() to avoid truncation when bit shifting by PAGE_SHIFT. I kept the same namespace (xpmap_) to avoid code churn. [1] http://mail-index.netbsd.org/port-xen/2009/05/09/msg004951.html XXX will document ptoa/atop/trunc_page separately.

Retire XEN_COMPAT_030001 as detailed on port-xen@: http://mail-index.netbsd.org/port-xen/2012/06/25/msg007431.html The xen_p2m API comes next. ok bouyer@. Tested on i386 PAE and amd64 (Xen 3.3 on private test bed, and Xen 3.4 for Amazon EC2). FWIW, Amazon always reported: hypervisor0 at mainbus0: Xen version 3.4.3-kaos_t1micro multiple times for Europe and US West-1, so I guess they are now at 3.4 (32 and 64 bits).

Fortunably, all addresses dissaemble to the same code. Because of this we always use the code intended for bootstrap, which doesn't use cross-calls or lock. 2 once 1 above is fixed, xen_kpm_sync() will use xcalls to sync other CPUs, which cause it to sleep and pmap.c doesn't like that. It triggers this KASSERT() in pmap_unmap_ptes(): KASSERT(pmap->pm_ncsw == curlwp->l_ncsw); 3 pmap->pm_cpus is not safe for the purpose of xen_kpm_sync(), which needs to know on which CPU a pmap is loaded *now*: pmap->pm_cpus is cleared before cpu_load_pmap() is called to switch to a new pmap, leaving a window where a pmap is still in a CPU's ci_kpm_pdir but not in pm_cpus. As a virtual CPU may be preempted by the hypervisor at any time, it can be large enough to let another CPU free the PTP and reuse it as a normal page. To fix 2), avoid cross-calls and IPIs completely, and instead use a mutex to update all CPU's ci_kpm_pdir from the local CPU. It's safe because we just need to update the table page, a tlbflush IPI will happen later. As a side effect, we don't need a different code for bootstrap, fixing 1). The mutex added to struct cpu needs a small headers reorganisation. to fix 3), introduce a pm_xen_ptp_cpus which is updated from cpu_pmap_load(), whith the ci_kpm_mtx mutex held. Checking it with ci_kpm_mtx held will avoid overwriting the wrong pmap's ci_kpm_pdir. While there I removed the unused pmap_is_active() function; and added some more details to DIAGNOSTIC panics. When using uvm_km_pgremove_intrsafe() make sure mappings are removed before returning the pages to the free pool. Otherwise, under Xen, a page which still has a writable mapping could be allocated for a PDP by another CPU and the hypervisor would refuse it (this is PR port-xen/45975). For this, move the pmap_kremove() calls inside uvm_km_pgremove_intrsafe(), and do pmap_kremove()/uvm_pagefree() in batch of (at most) 16 entries (as suggested by Chuck Silvers on tech-kern@, see also http://mail-index.netbsd.org/tech-kern/2012/02/17/msg012727.html and followups). Avoid early use of xen_kpm_sync(); locks are not available at this time. Don't call cpu_init() twice. Makes LOCKDEBUG kernels boot again Revert pmap_pte_flush() -> xpq_flush_queue() in previous.

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.

Use only one function to pin pages with Xen, and provide macros to call it for different levels (L1 => L4). Replace all calls to xpq_queue_pin_table(...) in MD code with these new functions, with proper #ifdef'ing depending on $MACHINE. Rationale: - only one function to modify for logging - pushes responsibility to caller for chosing the proper pin level, rather than Xen internal functions; this makes the pin level explicit rather than implicit. Boot tested for dom0 i386/amd64, PAE included. No functional change intended.

Welcome PAE inside i386 current.
This patch is inspired by work previously done by Jeremy Morse, ported by me
to -current, merged with the work previously done for port-xen, together with
additionals fixes and improvements.
PAE option is disabled by default in GENERIC (but will be enabled in ALL in
the next few days).
In quick, PAE switches the CPU to a mode where physical addresses become
36 bits (64 GiB). Virtual address space remains at 32 bits (4 GiB). To cope
with the increased size of the physical address, they are manipulated as
64 bits variables by kernel and MMU.
When supported by the CPU, it also allows the use of the NX/XD bit that
provides no-execution right enforcement on a per physical page basis.
Notes:
- reworked locore.S
- introduce cpu_load_pmap(), used to switch pmap for the curcpu. Due to the
different handling of pmap mappings with PAE vs !PAE, Xen vs native, details
are hidden within this function. This helps calling it from assembly,
as some features, like BIOS calls, switch to pmap_kernel before mapping
trampoline code in low memory.
- some changes in bioscall and kvm86_call, to reflect the above.
- the L3 is "pinned" per-CPU, and is only manipulated by a
reduced set of functions within pmap. To track the L3, I added two
elements to struct cpu_info, namely ci_l3_pdirpa (PA of the L3), and
ci_l3_pdir (the L3 VA). Rest of the code considers that it runs "just
like" a normal i386, except that the L2 is 4 pages long (PTP_LEVELS is
still 2).
- similar to the ci_pae_l3_pdir{,pa} variables, amd64's xen_current_user_pgd
becomes an element of cpu_info (slowly paving the way for MP world).
- bootinfo_source struct declaration is modified, to cope with paddr_t size
change with PAE (it is not correct to assume that bs_addr is a paddr_t when
compiled with PAE - it should remain 32 bits). bs_addrs is now a
void * array (in bootloader's code under i386/stand/, the bs_addrs
is a physaddr_t, which is an unsigned long).
- fixes in multiboot code (same reason as bootinfo): paddr_t size
change. I used Elf32_* types, use RELOC() where necessary, and move the
memcpy() functions out of the if/else if (I do not expect sym and str tables
to overlap with ELF).
- 64 bits atomic functions for pmap
- all pmap_pdirpa access are now done through the pmap_pdirpa macro. It
hides the L3/L2 stuff from PAE, as well as the pm_pdirpa change in
struct pmap (it now becomes a PDP_SIZE array, with or without PAE).
- manipulation of recursive mappings ( PDIR_SLOT_{,A}PTEs ) is done via
loops on PDP_SIZE.

No objection raised on port-i386@ and port-xen@R for about a week.
XXX kvm(3) will be fixed in another patch to properly handle both PAE and !PAE
kernel dumps (VA => PA macros are slightly different, and need proper 64 bits
PA support in kvm_i386).
XXX Mixing PAE and !PAE modules may lead to unwanted/unexpected results. This
cannot be solved easily, and needs lots of thinking before being declared
safe (paddr_t/bus_addr_t size handling, PD/PT macros abstractions).

Fixes regarding paddr_t/pd_entry_t types in MD x86 code, exposed by PAE: - NBPD_* macros are set to the types that better match their architecture (UL for i386 and amd64, ULL for i386 PAE) - will revisit when paddr_t is set to 64 bits for i386 non-PAE. - type fixes in printf/printk messages (Use PRIxPADDR when printing paddr_t values, instead of %lx - paddr_t/pd_entry_t being 64 bits with PAE) - remove casts that are no more needed now that Xen2 support has been dropped Some fixes are from jmorse@ patches for PAE. Compile + tested for i386 GENERIC and XEN3 kernels. Only compile tested for amd64. Reviewed by bouyer@. See also http://mail-index.netbsd.org/tech-kern/2010/02/22/msg007373.html

Starting with Xen 3 API, MMU_EXTENDED_COMMAND (tlb flush, cache flush, page pinning/unpinning, set_ldt, invlpg) operations cannot be queued in the xpq_queue[] any more, as they use their own specific hypercall, mmuext_op(). Their associated xpq_queue_*() functions already call xpq_flush_queue() before issuing the mmuext_op() hypercall, which makes these xpq_flush_queue() calls not necessary. Rapidly discussed with bouyer@ in private mail. XEN3_DOM0/XEN3PAE_DOM0 tested through a build.sh release, amd64 was only compile tested. No regression expected.

- 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.

- rework the page pinning API, so that now a function is provided for each level of indirection encountered during virtual memory translations. Update pmap accordingly. Pinning looks cleaner that way, and it offers the possibility to pin lower level pages if necessary (NetBSD does not do it currently). - some fixes and comments to explain how page validation/invalidation take place during save/restore/migrate under Xen. L2 shadow entries from PAE are now handled, so basically, suspend/resume works with PAE. - fixes an issue reported by Christoph (cegger@) for xencons suspend/resume in dom0. TODO: - PAE save/restore is currently limited to single-user only, multi-user support requires modifications in PAE pmap that should be discussed first. See the comments about the L2 shadow pages cached in pmap_pdp_cache in this commit. - grant table bug is still there; do not use the kernels of this branch to test suspend/resume, unless you want to experience bad crashes in dom0, and push the big red button. Now there is light at the end of the tunnel :) Note: XEN2 kernels will neither build nor work with this branch.

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@).

Merge the bouyer-xeni386 branch. This brings in PAE support to NetBSD xeni386
(domU only). PAE support is enabled by 'options PAE', see the new XEN3PAE_DOMU
and INSTALL_XEN3PAE_DOMU kernel config files.
See the comments in arch/i386/include/{pte.h,pmap.h} to see how it works.
In short, we still handle it as a 2-level MMU, with the second level page
directory being 4 pages in size. pmap switching is done by switching the
L2 pages in the L3 entries, instead of loading %cr3. This is almost required
by Xen, which handle the last L2 page (the one mapping 0xc0000000 - 0xffffffff)
in a very special way. But this approach should also work for native PAE
support if ever supported (in fact, the pmap should almost suport native
PAE, what's missing is bootstrap code in locore.S).

Snapshot of work in progress: an Xen i386PAE kernel boots and start init on a amd64 dom0, but panics when init forks. This code needs a lot of cleanup, and the pmap handling is minimal to allow init to start. It's a proof of concept of how PAE on Xen can work. For PAE guest, the Xen MMU handling differs in some significant way from the i386 or amd64 Xen. The L3 page has only 4 entries, the last one mapping 0xc0000000->0xffffffff (which happens to be our kenrel VM range, that's cool). The L2 page pointed to by this last entry is handled specially by Xen because it contains some Xen private mapping, including a recursive mapping. So this page can only be pointed to by exactly one L3 entry, and nothing else (it can't be part of a recursive mapping for example). In addition, it would waste too much VA space to do recursive mapping at the L3 level. We do pmap switching at the L# level, instead of doing it though %cr3. %cr3 is static, as is L3[3] which contains only kenrel mappings. pmap_load() does pmap switching though the first 3 entries for L3. PTE mapping is done though 4 contigous L2 entries; the last one pointing to a shadow of L3[3]. This way we can consider we have a 2-level VM system, but with the L2 being 4 pages in size instead of one. The plx_i() macros can be used with it to access the PTE without changes. This can be reused as is for native PAE support (without the L3[3] shadow which wouldn't be needed here)

Finish sync with HEAD. Especially use the new x86 pmap for xenamd64. For this: - rename pmap_pte_set() to pmap_pte_testset() - make pmap_pte_set() a function or macro for non-atomic PTE write - define and use pmap_pa2pte()/pmap_pte2pa() to read/write PTE entries - define pmap_pte_flush() which is a nop in x86 case, and flush the MMUops queue in the Xen case
