Bypass ACPI_NOTIFY_DEVICE_WAKE also in acpilid(4). Use aprint_debug_dev(9)

Implement enough of a SCSI target to be able to perform tests on
our SCSIPI driver stack.  Currently we pretend to be a single CD
controller with an optional host file as the image, but I guess
the sky's the limit.

As all reported P-state failures so far have centered around the status-
check (today it was christos@' laptop), follow Linux and disable this rather
expensive sanity-check for the time being. A hypothesis about the cause of
the failures relates to the absence of cross-CPU coordination in the current
implementation.

(jruoho)

Backport improvements from FreeBSD.
Introduce two new options:
-f : force root node
-i : set priority budget where supported
developped, tested and reviewed by kiyohara@ and me.

(cegger)

Add native support for AMD family 0Fh processors. This is the furthest we
will go backwards; K7 will not be supported already due doubts about
availability and reliability of ACPI during that era. Some unfortunate code
duplication is present (but not overly much). Thanks to cegger@ and jakllsch@
for patiently testing this.

(jruoho)

Few small nits.

Initialize acpi_force_load so that it gets allocated in the data segment

update component lists: scsipi is independent of umass now

(pooka)

add rumpdev_scsipi

(pooka)

Fix issues with stack allocation and pax aslr:
- since the size is unsigned, don't check just that it is > 0, but limit
  it to the MAXSSIZ
- if the stack size is reduced because of aslr, make sure we reduce the
  actual allocation by the same size so that the size does not wrap around.
NB: Must be pulled up to 5.x!

(christos)

Split scsipi out of librumpdev_umass into librumpdev_scsipi.  umass
still compile time depends on scsipi in the sense of "ifdef
NATAPIBLUES", but I'm not going to fix that now.

(pooka)

Convert one second(!!) delay to kpause.  It was originally done
from a callout, so delay was the only option (in those days).  Then
the caller was converted to a thread, but left as a delay.  It
still may block the scsipi completion thread processing (so I
seriously doubt this code path is executed very often on a live
system).

(pooka)

Added rumpdev, rumpdev_putter and rumpdev_disk to LDADD for fs-utils binaries

(stacktic)

Add #include <sys/param.h> for howmany().

Other entry points beyond x86_cpu_idle_halt() may use HLT as the

Simplify.

(joerg)

Initialize the new kernconfig_lock for rump kernels before it can be used.

Should fix the rather massive breakage in the automated test runs, too.
Sorry for breaking rump.

(pgoyette)

Add a delay between startup of pinger and pingee here too.

XXX: there's apparently some race condition which appears to trigger
if a broadcast arp arrives around the same time as the arpwhohas

arpwhohas requestor.  If this rings a bell to someone, please let
me know.

(jnemeth)

Move FWH chip detection area entirely within the mapping for

Add more articles and more formatting.

(wiz)

Import NPF - a packet filter.  Some features:

- Designed to be fully MP-safe and highly efficient.

- Tables/IP sets (hash or red-black tree) for high performance lookups.

- Stateful filtering and Network Address Port Translation (NAPT).
  Framework for application level gateways (ALGs).

- Packet inspection engine called n-code processor - inspired by BPF -
  supporting generic RISC-like and specific CISC-like instructions for
  common patterns (e.g. IPv4 address matching).  See npf_ncode(9) manual.

- Convenient userland utility npfctl(8) with npf.conf(8).

NOTE: This is not yet a fully capable alternative to PF or IPFilter.
Further work (support for binat/rdr, return-rst/return-icmp, common ALGs,
state saving/restoring, logging, etc) is in progress.

Thanks a lot to Matt Thomas for various useful comments and code review.

(perry)

Revive S.R. Bourne's original tutorial on using the Bourne Shell.
This initial commit consists of the files as they existed in 4.4BSD,

Don't put devices in the ignored IDs list just because no driver exists.

(jmcneill)

avoid false positives when matching a (non-existent) encryption subkey

use debugging output to point to the matching key

(agc)

After discussion with jakllsch@ and jmcneill@, revert the previous and only
do the status-check when the comparison value reported by BIOS is not zero.
The uncertainty noted in the previous commit still applies. But if we ever
see a timeout again, it will likely be either a firmware bug or a special
case like the Intel Turbo Boost.

(jruoho)

I guess people still attach com & lpt to isa, so don't skip legacy devices.

(jmcneill)

If ACPI is active and the FADT reports no legacy devices present, set
the 'no-legacy-devices' property to true on isa0.

(jmcneill)

If the 'no-legacy-devices' property is present and true, skip device
enumeration.

(jmcneill)

in acpibut_notify_handler, suppress 'unknown event' messages for
ACPI_NOTIFY_DEVICE_WAKE. Control method power and sleep buttons can
generate this event upon waking from G1 sleep to indicate that it was
responsible for waking the system.

(jmcneill)

Add support for parsing the data format "@<seconds since epoch>" e.g.
"@735275209" for "Tue Apr 20 03:06:49 UTC 1993". This change was inspired
by coreutil's "date" utility.

(tron)

When we do the sanity check that a P- or T-state transition was successful,
compare also against the control-field. There appears to be many BIOSes in
the field that report a zero value in the status-field. It is unclear whether
this should be taken as a hint that the status-check is not necessary also
during P-state transitions. If we still see timeouts (EAGAIN), this should
be reverted and the status-check should be bypassed if ps->ps_status is 0.

(jruoho)

Fix botched update.

(pgoyette)

Include DHparams_print_fp

(joerg)

Put a valid date here - no more placeholder.

(pgoyette)

Add a new atf test-case to check that recursive module calls actually work.

(pgoyette)

Add the new kern_cfglock.c to rump.

(pgoyette)

Update the rest of the kernel to conform to the module subsystem's new
locking protocol.

(pgoyette)

Update the various xxx_verbose modules to conform to the module subsystem's
new locking protocol.

(pgoyette)

Define a set of new kernel locking primitives to implement the recursive
kernconfig_mutex.  Update module subsystem to use this mutex rather than
its own internal (non-recursive) mutex.  Make module_autoload() do its
own locking to be consistent with the rest of the module_xxx() calls.
Update module(9) man page appropriately.

As discussed on tech-kern over the last few weeks.

Welcome to NetBSD 5.99.39 !

- don't clobber the data found by _PSS if XPSS validation fails
- XPSS spec says that Status{,Mask} and Control{,Mask} buffers are 8 bytes
- use ACPI_GET64 macros instead of memcpy when reading from buffers

malformed XPSS packages but has a working _PSS

(jruoho)

Add a comment.

(jruoho)

Check from CPUID 0x06 %eax (on Intel) whether we might actually have an
invariant APIC timer or an "ARAT" ("always running APIC timer"). This means
that the APIC timer may keep ticking at the same rate also in deep C-states
with some new or forthcoming Intel CPUs.

PRBS, RX, TX, UI, VID, WDT, XBAR, XIP.

(jruoho)

Add a quirk for Turbo Boost.

It was observed that at least Sverre Froyen's ThinkPad T500 reports values
that do not match readings from the IA32_PERF_STATUS register. This only
applied to the P0-state. Thus, for now, skip the status check if Turbo
Boost has been detected and the requested state is P0.

This needs to be revisited once Turbo Boost actually works in NetBSD. It is
unclear whether this is a BIOS flaw or not; these values may well be what we
get from IA32_PERF_STATUS once the CPU actually uses the +133.33 MHz boost.

(jruoho)

Detect Intel's Turbo Boost and presence of IA32_APERF/IA32_MPERF. The former
is required for a quirk, and the latter is needed for hardware P-state
coordination (once acpicpu(4) will support fine-grained coordination).

(jruoho)

Detect whether TSC is invariant, which may be the case on both new AMD and
Intel processors. The invariance means that TSC runs at a constant rate
during all ACPI state changes. If it is variant, skew may occur and TSC is
generally unsuitable for wall clock services. This is especially relevant
with C-states; with variant TSC, the whole counter may be stopped with states
larger than C1. All x86 CPUs before circa mid-2000s can be assumed to have a
variant time stamp counter.

(jruoho)

Add upgt(4), Intersil PrismGT USB 802.11b/g adapter.

(tsutsui)

Add IA32_MPERF (E7h) and IA32_APERF (E8h) as MSR_MPERF and MSR_APERF.

(jruoho)

Properly detect AMD hardware P-state support. Also detect "core boost" (only
present in some models of family 10h).

(jruoho)

Add CPUID_APM_CPB at Fn8000_0007 %edx, for core performance boost.

(jruoho)

Use a constant from <x86/specialreg.h>.

Remove stray {

(pooka)

PT_STEP historically ignores the argument. Indepent of whether this
behavior will be restored, pass down 0 for now to unbreak single
stepping after the thread changes.

(joerg)

Consider a mapped IPv4 address of 0.0.0.0 as unspecified. This allows
using mapped IPv4 address with connect without preceding bind.

(joerg)

Allow ELF objects with more than two PT_LOAD sections. Go creates such
binaries by default with separate sections for executable, writeable
data and constants. Use the same heuristic as FreeBSD to match up the
text and data segment assumptions.

(joerg)

Add two flags that needs to be dealt with (hardware vs. software
coordination of P-state transitions, and Turbo Boost / Turbo Core).

(matt)

Deal with autoconfiguration madness by using config_defer(9) to defer

(macallan)

Add a two-way floodping test and a test which sends icmp echos with

(pooka)

Check the status of P- and T-state transformations on all CPUs. This is
still not ideal, as ACPI gives us information about "cross logical processor
dependencies". For instance, a single MSR call on one CPU may cause all other
CPUs in the same domain to follow the state shift. Thus, rather than using
xc_broadcast(9), we should xc_unicast(9) on per-domain or per-CPU-set basis.
