Apply patch proposed in PR port-xen/45975 (this does not solve the exact problem reported here but is part of the solution): xen_kpm_sync() is not working as expected, leading to races between CPUs. 1 the check (xpq_cpu != &x86_curcpu) is always false because we have different x86_curcpu symbols with different addresses in the kernel. 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.

Expose the PG_k #define pt/pd bit to both xen and "baremetal" x86. This is required, since kernel pages are mapped with user permissions in XEN/amd64 since the VM kernel runs in ring3. Since XEN/i386(including PAE) runs in ring1, supervisor mode is appropriate for these ports. We need to share this since the pmap implementation is still shared. Once the xen implementation is sufficiently independant of the x86 one, this can be made private to xen/include/xenpmap.h

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.

Welcome to 5.99.53! Merge rmind-uvmplock branch: - Reorganize locking in UVM and provide extra serialisation for pmap(9). New lock order: [vmpage-owner-lock] -> pmap-lock. - Simplify locking in some pmap(9) modules by removing P->V locking. - Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs). - Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner. Add TLBSTATS option for x86 to collect statistics about TLB shootdowns. - Unify /dev/mem et al in MI code and provide required locking (removes kernel-lock on some ports). Also, avoid cache-aliasing issues. Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches formed the core changes of this branch.

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.
See also http://mail-index.netbsd.org/port-i386/2010/07/17/msg002062.html
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).

Ephemeral mapping (emap) implementation. Concept is based on the idea that activity of other threads will perform the TLB flush for the processes using emap as a side effect. To track that, global and per-CPU generation numbers are used. This idea was suggested by Andrew Doran; various improvements to it by me. Notes: - For now, zero-copy on pipe is not yet enabled. - TCP socket code would likely need more work. - Additional UVM loaning improvements are needed. Proposed on <tech-kern>, silence there.

- Don't bother using sse to copy/zero pages on demand. It turns out not to be worth it. - If the machine has sse, re-enable zeroing pages in the idle loop and use the sse instructions so that we don't blow out the cache.

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).

- rewrite P->V tracking. - use a hash rather than SPLAY trees. SPLAY tree is a wrong algorithm to use here. will be revisited if it slows down anything other than micro-benchmarks. - optimize the single mapping case (it's a common case) by embedding an entry into mdpage. - don't keep a pmap pointer as it can be obtained from ptp. (discussed on port-i386 some years ago.) ideally, a single paddr_t should be enough to describe a pte. but it needs some more thoughts as it can increase computational costs. - pmap_enter: simplify and fix races with pmap_sync_pv. - don't bother to lock pm_obj[i] where i > 0, unless DIAGNOSTIC. - kill mp_link to save space. - add many KASSERTs.

Merge the bouyer-xeni386 branch to head, at tag bouyer-xeni386-merge1 (the branch is still active and will see i386PAE support developement). Sumary of changes: - switch xeni386 to the x86/x86/pmap.c, and the xen/x86/x86_xpmap.c pmap bootstrap. - merge back most of xen/i386/ to i386/i386 - change the build to reduce diffs between i386 and amd64 in file locations - remove include files that were identical to the i386/amd64 counterparts, the build will find them via the xen-ma/machine link.
