# Options specific to AMD64 platform kernels
This is the start of the FreeBSD/x86_64 kernel.

Initial landing of SMP support for FreeBSD/amd64. - This is heavily derived from John Baldwin's apic/pci cleanup on i386. - I have completely rewritten or drastically cleaned up some other parts. (in particular, bootstrap) - This is still a WIP. It seems that there are some highly bogus bioses on nVidia nForce3-150 boards. I can't stress how broken these boards are. I have a workaround in mind, but right now the Asus SK8N is broken. The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed. - Most of my testing has been with SCHED_ULE. SCHED_4BSD works. - the apic and acpi components are 'standard'. - If you have an nVidia nForce3-150 board, you are stuck with 'device atpic' in addition, because they somehow managed to forget to connect the 8254 timer to the apic, even though its in the same silicon! ARGH! This directly violates the ACPI spec.

Provide groundwork for 32-bit binary compatibility on non-x86 platforms, for upcoming 64-bit PowerPC and MIPS support. This renames the COMPAT_IA32 option to COMPAT_FREEBSD32, removes some IA32-specific code from MI parts of the kernel and enhances the freebsd32 compatibility code to support big-endian platforms.

#IBCS2 opt_dontuse.h
#COMPAT_LINUX opt_dontuse.h
Add preliminary support for running 32-bit Linux binaries on amd64, enabled with the COMPAT_LINUX32 option. This is largely based on the i386 MD Linux emulations bits, but also builds on the 32-bit FreeBSD and generic IA-32 binary emulation work. Some of this is still a little rough around the edges, and will need to be revisited before 32-bit and 64-bit Linux emulation support can coexist in the same kernel.

- change the example of compiling only specific modules to not contain the linux module, since it is not cross-platform - move linprocfs from "files" and "options" to architecture specific files, since it only makes sense to build this for those architectures, where we also have a linuxolator - disable the build of the linuxolator on our tier-2 architecture "Alpha": * we don't have a linux_base port which supports Alpha and at the same time is not outdated/obsoleted upstream/in a good condition/ currently working * the upcomming new default linux base port is based upon Fedora Core 3 (security support via http://www.fedoralegacy.org), which isn't available for Alpha (like the current default linux base port which is based upon Red Hat 8) * nobody answered my request for testing it ~1 month ago on current@ and alpha@ (it doesn't surprises me, see above) * a SoC student wouldn't have to waste time on something which nobody is willing to test This does not remove the alpha specific MD files of the linuxolator yet.

LINSYSFS opt_dontuse.h
Add support for Windows/x86-64 binaries to Project Evil. Ville-Pertti Keinonen (will at exomi dot comohmygodnospampleasekthx) deserves a big thanks for submitting initial patches to make it work. I have mangled his contributions appropriately. The main gotcha with Windows/x86-64 is that Microsoft uses a different calling convention than everyone else. The standard ABI requires using 6 registers for argument passing, with other arguments on the stack. Microsoft uses only 4 registers, and requires the caller to leave room on the stack for the register arguments incase the callee needs to spill them. Unlike x86, where Microsoft uses a mix of _cdecl, _stdcall and _fastcall, all routines on Windows/x86-64 uses the same convention. This unfortunately means that all the functions we export to the driver require an intermediate translation wrapper. Similarly, we have to wrap all calls back into the driver binary itself. The original patches provided macros to wrap every single routine at compile time, providing a secondary jump table with a customized wrapper for each exported routine. I decided to use a different approach: the call wrapper for each function is created from a template at runtime, and the routine to jump to is patched into the wrapper as it is created. The subr_pe module has been modified to patch in the wrapped function instead of the original. (On x86, the wrapping routine is a no-op.) There are some minor API differences that had to be accounted for: - KeAcquireSpinLock() is a real function on amd64, not a macro wrapper around KfAcquireSpinLock() - NdisFreeBuffer() is actually IoFreeMdl(). I had to change the whole NDIS_BUFFER API a bit to accomodate this. Bugs fixed along the way: - IoAllocateMdl() always returned NULL - kern_windrv.c:windrv_unload() wasn't releasing private driver object extensions correctly (found thanks to memguard) This has only been tested with the driver for the Broadcom 802.11g chipset, which was the only Windows/x86-64 driver I could find.

Remove sio(4) and related options from MI files to amd64, i386 and pc98 MD files. Remove nodevice and nooption lines specific to sio(4) from ia64, powerpc and sparc64 NOTES. There were no such lines for arm yet. sio(4) is usable on less than half the platforms, not counting a future mips platform. Its presence in MI files is therefore increasingly becoming a burden.

CONSPEED opt_sio.h

Allow the sio acpi attachment to be disabled (ie: use hints only). This hack means you can get the units and flags to match up more easily with serial consoles on machines with acpi tables that cause the com ports to be probed in the wrong order (and hence get the wrong sio unit number). This replaces the common alternative hack of editing the code to comment out the acpi attachment. This could go away entirely when device wiring patches are committed.

DEV_ATPIC opt_atpic.h
Implement an alternate method to stop CPUs when entering DDB. Normally we use a regular IPI vector, but this vector is blocked when interrupts are disabled. With "options KDB_STOP_NMI" and debug.kdb.stop_cpus_with_nmi set, KDB will send an NMI to each CPU instead. The code also has a context-stuffing feature which helps ddb extract the state of processes running on the stopped CPUs. KDB_STOP_NMI is only useful with SMP and complains if SMP is not defined. This feature only applies to i386 and amd64 at the moment, but could be used on other architectures with the appropriate MD bits. Submitted by: ups

Add isci(4) driver for amd64 and i386 targets. The isci driver is for the integrated SAS controller in the Intel C600 (Patsburg) chipset. Source files in sys/dev/isci directory are FreeBSD-specific, and sys/dev/isci/scil subdirectory contains an OS-agnostic library (SCIL) published by Intel to control the SAS controller. This library is used primarily as-is in this driver, with some post-processing to better integrate into the kernel build environment. isci.4 and a README in the sys/dev/isci directory contain a few additional details. This driver is only built for amd64 and i386 targets. Sponsored by: Intel Reviewed by: scottl Approved by: scottl

Add support for new Intel on-CPU Bull Mountain random number generator, found on IvyBridge and supposedly later CPUs, accessible with RDRAND instruction. From the Intel whitepapers and articles about Bull Mountain, it seems that we do not need to perform post-processing of RDRAND results, like AES-encryption of the data with random IV and keys, which was done for Padlock. Intel claims that sanitization is performed in hardware. Make both Padlock and Bull Mountain random generators support code covered by kernel config options, for the benefit of people who prefer minimal kernels. Also add the tunables to disable hardware generator even if detected. Reviewed by: markm, secteam (simon) Tested by: bapt, Michael Moll <kvedulv@kvedulv.de> MFC after: 3 weeks
