On Xen, there is variable-sized Xen data after the kernel's text+data+bss (this include the physical->machine table). (vaddr_t)(KERNBASE + NKL2_KIMG_ENTRIES * NBPD_L2) is after text+data+bss but, on a domU with lots of RAM (more than 4GB) (so large xpmap_phys_to_machine_mapping table) this can point to some of Xen's data setup at bootstrap (either the xpmap_phys_to_machine_mapping table, some page shared with the hypervisor, or our kernel page table). Using it for early_zerop will cause of these pages to be unmapped after bootstrap. This will cause a kernel page fault for the domU, either immediatly or eventually much later, depending on where early_zerop points to. To fix this, account for early_zerop when building the bootstrap pages, and its VA from here. May fix PR port-xen/38699

- Make pmap_write_protect() work with pmap_kernel() too ((va & L2_FRAME) strips the high bits of a LP64 address) - use pmap_protect() in pmap_pdp_ctor() to remap the PDP read-only instead of (ab)using pmap_kenter_pa(). No more "mapping already present" on console with DIAGNOSTIC kernels - make sure to zero the whole PDP (NTOPLEVEL_PDES doens't include high-level entries on i386 and i386PAE, reserved by Xen). Not sure how it has worked before - remove an always-true test (&& pmap != pmap_kernel(); we KASSERT that at the function entry).

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.

amd64/Xen doesn't require special treatment for pmap_is_curpmap(), since cpu_load_pmap() ensures that the linear map is in place for the kernel. This emulates normal shared kernel mappings, except for the recursive mapping of the PDP_BASE, which will point to the per-cpu pdir, which will be a copy of the pmap_kernel()->pm_pdir; instead of the user pmap->pm_pdir.

On xen, prevent cached PDP objects from being reused by pool_cache(9), since they are "pinned" on the hypervisor and thus R/O for the domU. Separately, after every per-cpu pmap pdir entry reset, make sure that the corresponding L3 PTP pointers are flushed from all cpus with the pmap loaded. Enforce this immediately via pmap_tlb_shootnow();

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.

- Rather use pmap_pte_set() when modifying a PTE. - Call pmap_pte_flush() when issuing PTE modifications. While it is a NOOP for native x86, it is not for Xen. It will flush all operations that are possibly waiting in the queue, like xpq_queue_pte_update(). Do it for each level, this function is only called at boot time and is not performance critical. While here: - No need to cast early_zerop to void with memset(). - Move common variables out of the #ifdef's. - KNF

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).

Check the virtual address 'va' for each PDIR_SLOT_PTE entry. PDP_SIZE is 4 with PAE (Xen only currently), 1 otherwise: loop should be unrolled when PDP_SIZE is 1. pmap_alloc_level() is used by pmap_growkernel(), the PDE is a kernel mapping: mark it so with PG_k. While here, use pmap_pa2pte() for physical address 'pa'. No functional change.

This patch fixes the NX regression issue observed on amd64 kernels, where per-page execution right was disabled (therefore leading to the inability of the kernel to detect fraudulent use of memory mappings marked as not being executable). - replace cpu_feature and ci_feature_flags variables by cpu_feature and ci_feat_val arrays. This makes it cleaner and brings kernel code closer to the design of cpuctl(8). A warning will be raised for each CPU that does not expose the same features as the Boot Processor (BP). - the blacklist of CPU features is now a macro defined in the specialreg.h header, instead of hardcoding it inside MD initialization code; fix comments. - replace checks against CPUID_TSC with the cpu_hascounter() function. - clean up the code in init_x86_64(), as cpu_feature variables are set inside cpu_probe(). - use cpu_init_msrs() for i386. It will be eventually used later for NX feature under i386 PAE kernels. - remove code that checks for CPUID_NOX in amd64 mptramp.S, this is already performed by cpu_hatch() through cpu_init_msrs(). - remove cpu_signature and feature_flags members from struct mpbios_proc (they were never used). This patch was tested with i386 MONOLITHIC, XEN3PAE_DOM0 and XEN3_DOM0 under a native i386 host, and amd64 GENERIC, XEN3_DOM0 via QEMU virtual machines. XXX Should kernel rev be bumped? XXX A similar patch should be pulled-up for NetBSD-5, hopefully tomorrow.

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.

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.

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.

PR port-i386/40143 Viewing an mpeg transport stream with mplayer causes crash Fix numerous problems: 1. LDT updates are not atomic. 2. Number of processes running with private LDTs and/or I/O bitmaps is not capped. System with high maxprocs can be paniced. 3. LDTR can be leaked over context switch. 4. GDT slot allocations can race, giving the same LDT slot to two procs. 5. Incomplete interrupt/trap frames can be stacked. 6. In some rare cases segment faults are not handled correctly.

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).

add functions to update pm_stats and use them in some places. for pmap_kernel(), use atomic ops to update stats because pmap_map_ptes doesn't lock the pmap.

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.

Reorder some operations for better handling of failures in xpq_update_foreign(). Note that this also affects native operations, but it shoulnd't cause problems even for SMP system. Proposed on port-amd64@ and port-i386@ Don't invalidate the recursive PTE entry in user pmap when switching from kernel to userland on Xen/amd64. This effectively means that a userland process can read its own page tables (no write, of course) on Xen/amd64, but it shouldn't cause security issue (discussed on tech-kern@ some time ago). This makes NetBSD Xen/amd64 more than 10x faster building pkgsrc/pkgtools/digest

- When computing the TSC frequency, call i8254_delay() and not DELAY().
- Use atomics to adjust the pmap reference count, instead of taking locks.
- Implement I386_{SET,GET}_{FS,GS}BASE, allowing %fs and %gs to be used
as per-thread registers. This is compatible with FreeBSD.
- Run patches after we have attached CPUs, since we then know if the
system is uniprocessor or not. Eliminates a lot of #ifdef MULTIPROCESSOR
and makes running MP kernels on UP systems cheaper.
- Patch out many of the 'lock' prefixes to nops if uniprocessor.
- Do a wbinvd after patching to ensure that the trace/instruction cache
is up to date.
