With recent introduction of conditionals for the various MP options, we broke the build for x86 systems that have MULTIPROCESSOR but which do not include MPBIOS. So let's try to untangle things just a bit. Presented on current-users (and referenced on source-changes-d) without any comment. XXX We really should find a better method to select kernel options; #ifdef spaghetti is rather sub-optimal.

in cpu_boot_secondary_processors(), wait until all the other CPUs have registered themselves in kcpuset_running before returning. recent changes to the TLB invalidation xcall code assume that any CPU which will receive a broadcast IPI is registered in kcpuset_running, so ensure that is true by waiting here.

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.

Don't shutdown the boostrap processor (BSP) because we may have to run BIOS methods on it. For example, ACPI requires that we execute the code for changing sleep state on the BSP. This may help the problem where folks' machines would hang instead of powering off when they entered ACPI sleep state 5. XXX If the BSP is already shut down, we should start it back up.

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.

Revert the previous changes to EST. The used hack had an obvious flaw: the acpicpu(4) driver should attach even if the existing frequency management code fails to attach, mainly because ACPI is the only proper way to deal with EST on new Intel system. Use a more drastic hack to deal with this: when acpicpu(4) attachs, it tears down any existing sysctl(8) controls and installs identical ones in place. Upon detachment, the initialization function of the existing EST is called.

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).

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.

Improve x86 tsc handling: - Ditch the cross-CPU calibration stuff. It didn't work properly, and it's near impossible to synchronize the CPUs in a running system, because bus traffic will interfere with any calibration attempt, messing up the timings. - Only enable the TSC on CPUs where we are sure it does not drift. If we are On a known good CPU, give the TSC high timecounter quality, making it the default. - When booting CPUs, detect TSC skew and account for it. Most Intel MP systems have synchronized counters, but that need not be true if the system has a complicated bus structure. As far as I know, AMD systems do not have synchronized TSCs and so we need to handle skew. - While an AP is waiting to be set running, try and make the TSC drift by entering a reduced power state. If we detect drift, ensure that the TSC does not get a high timecounter quality. This should not happen and is only for safety. - Make cpu_counter() stuff LKM safe.

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.
