Use pmap_mapbios() to map ACPI tables on amd64 and i386. The ACPI table-mapping code used pmap_kenter_temporary() to create mappings, which in turn uses the fixed-size crashdump map. Moreover, the code was not verifying that the table fits in this map, so when mapping large tables we could clobber adjacent mappings. This use of pmap_kenter_temporary() appears to predate support in pmap_mapbios() for creating early mappings, but that restriction no longer applies.

sys/amd64: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

If x86 CPU implementation of the MWAIT instruction reasonably interacts with interrupts, query ACPI and use MWAIT for entrance into Cx sleep states. Support C1 "I/O then halt" mode. See Intel' document 302223-007 "Intelб╝ Processor Vendor-Specific ACPI Interface Specification" for description. Move the acpi_cpu_c1() function into x86/cpu_machdep.c and use it instead of inlining "sti; hlt" sequence in several places. In the acpi(4) man page, besides documenting the dev.cpu.N.cx_methods sysctl, correct the names for dev.cpu.N.{cx_usage,cx_lowest,cx_supported} sysctls. Both jkim and avg have some other patches implementing the mwait functionality; this work is unrelated. Linux does not rely on the ACPI to provide correct tables describing Cx modes. Instead, the driver has pre-defined knowledge of the CPU models, it was supplied by Intel. Tested by: pho (previous versions) Sponsored by: The FreeBSD Foundation

Extend the meaning of the CTLFLAG_TUN flag to automatically check if there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.

Rework how the nexus(4) device works on x86 to better handle the idea of different "platforms" on x86 machines. The existing code already handles having two platforms: ACPI and legacy. However, the existing approach was rather hardcoded and difficult to extend. These changes take the approach that each x86 hardware platform should provide its own nexus(4) driver (it can inherit most of its behavior from the default legacy nexus(4) driver) which is responsible for probing for the platform and performing appropriate platform-specific setup during attach (such as adding a platform-specific bus device). This does mean changing the x86 platform busses to no longer use an identify routine for probing, but to move that logic into their matching nexus(4) driver instead. - Make the default nexus(4) driver in nexus.c on i386 and amd64 handle the legacy platform. It's probe routine now returns BUS_PROBE_GENERIC so it can be overriden. - Expose a nexus_init_resources() routine which initializes the various resource managers so that subclassed nexus(4) drivers can invoke it from their attach routine. - The legacy nexus(4) driver explicitly adds a legacy0 device in its attach routine. - The ACPI driver no longer contains an new-bus identify method. Instead it exposes a public function (acpi_identify()) which is a probe routine that the MD nexus(4) drivers can use to probe for ACPI. All of the probe logic in acpi_probe() is now moved into acpi_identify() and acpi_probe() is just a stub. - On i386 and amd64, an ACPI-specific nexus(4) driver checks for ACPI via acpi_identify() and claims the nexus0 device if the probe succeeds. It then explicitly adds an acpi0 device in its attach routine. - The legacy(4) driver no longer knows anything about the acpi0 device. - On ia64 if acpi_identify() fails you basically end up with no devices. This matches the previous behavior where the old acpi_identify() would fail to add an acpi0 device again leaving you with no devices. Discussed with: imp Silence on: arch@

Commit MD parts of a loosely functional AMD64 port. This is based on a heavily stripped down FreeBSD/i386 (brutally stripped down actually) to attempt to get a stable base to start from. There is a lot missing still. Worth noting: - The kernel runs at 1GB in order to cheat with the pmap code. pmap uses a variation of the PAE code in order to avoid having to worry about 4 levels of page tables yet. - It boots in 64 bit "long mode" with a tiny trampoline embedded in the i386 loader. This simplifies locore.s greatly. - There are still quite a few fragments of i386-specific code that have not been translated yet, and some that I cheated and wrote dumb C versions of (bcopy etc). - It has both int 0x80 for syscalls (but using registers for argument passing, as is native on the amd64 ABI), and the 'syscall' instruction for syscalls. int 0x80 preserves all registers, 'syscall' does not. - I have tried to minimize looking at the NetBSD code, except in a couple of places (eg: to find which register they use to replace the trashed %rcx register in the syscall instruction). As a result, there is not a lot of similarity. I did look at NetBSD a few times while debugging to get some ideas about what I might have done wrong in my first attempt.
