# Options specific to the i386 platform kernels
Create a special option file "opt_global.h" which is included by all source files via a 'cc -include opt_global.h ...' type arrangement. This means we can untangle certain header files. options.i386 has a placeholder until it has a real member so we can avoid having to teach config about it just yet. Reviewed by: bde

MAXMEM
Disable probing of HTT CPUs by default for the MP Table case. HTT CPUs should only be used if they are enabled in the BIOS. Now that we support enumerating CPUs using the ACPI MADT, any HTT machine using ACPI should respect the BIOS setting. For HTT machines with ACPI disabled in the kernel, the MPTABLE_FORCE_HTT kernel option can be used to try to probe HTT CPUs like have done in the past for the MP Table case. This option should only be enabled if HTT is enabled in the BIOS.

COMPAT_LINUX opt_dontuse.h
- 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on our tier-2 architecture "Alpha": * we don't have a linux_base port which supports Alpha and at the same time is not outdated/obsoleted upstream/in a good condition/ currently working * the upcomming new default linux base port is based upon Fedora Core 3 (security support via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
Man the liferafts! Here comes the long awaited SMP -> -current merge! There are various options documented in i386/conf/LINT, there is more to come over the next few days. The kernel should run pretty much "as before" without the options to activate SMP mode. There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment. This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code!

Introduce a new option, KVA_SPACE, which can be used to reconfigure the size of the kernel virtual address space relatively painlessly. Userland will adapt via the exported kernbase symbol. Increasing this causes the user part of address space to reduce.

When (1) CPU_PPRO2CELERON option is defined, (2) Intel CPU is found and (3) CPU ID is 0x66?, L2 cache is enabled through MSR 0x11e. The L2 cache latency value can be specified by CPU_L2_LATENCY option. Default value of L2 cache latency is 5. These options are useful if you use Socket 8 to Socket 370 converter (e.g. Power Leap's PL-Pro/II.) Most PentiumPro BIOSs don't enable L2 cache of Mendocino Celeron CPUs because they don't know Celeron CPUs. These options are needles if you use a Coppermine (FCPGA) Celeron or PentiumIII, becuase the L2 cache enable bit is hard wired and L2 cache is always enabled.

Make sure your kernel configuration file has the following line. options "VM86" If you want to statically link the VESA support code to the kernel, add the following option to the kernel configuration file. options "VESA" The vidcontrol command now accepts the following video mode names: VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600 The VESA_800x600 mode is a raster display mode. The 80x25 text will be displayed on the 800x600 screen. Useful for some laptop computers. vidcontrol accepts the new `-i <info>' option, where <info> must be either `adapter' or `mode'. When the `-i adapter' option is given, vidcontrol will print basic information (not much) on the video adapter. When the `-i mode' option is specified, vidcontrol will list video modes which are actually supported by the video adapter. Submitted by: Kazutaka YOKOTA yokota@FreeBSD.ORG

Keyboard driver update in preparation for the USB keyboard driver. - Refined internal interface in keyboard drivers so that: 1. the side effect of device probe is kept minimal, 2. polling mode function is added, 3. and new ioctl and configuration options are added (see below). - Added new ioctl: KDSETREPEAT Set keyboard typematic rate. There has existed an ioctl command, KDSETRAD, for the same purpose. However, KDSETRAD is dependent on the AT keyboard. KDSETREPEAT provides more generic interface. KDSETRAD will still be supported in the atkbd driver. - Added new configuration options: ATKBD_DFLT_KEYMAP Specify a keymap to be used as the default, built-in keymap. (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP, SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap. These options are now gone for good. The new option is more general.) KBD_DISABLE_KEYMAP_LOADING Don't allow the user to change the keymap.

DEV_APIC opt_apic.h
Handling all the three clocks (hardclock, softclock, profclock) with the LAPIC may lead to aliasing for softclock and profclock because frequencies are sized in order to fit mainly hardclock. atrtc used to take care of the softclock and profclock and it does still do, if the LAPIC can't handle the clocks properly. Revert the change when the LAPIC started taking charge of all three of them and let atrtc handle softclock and profclock if not explicitly requested. Such request can be made setting != 0 the new tunable machdep.lapic_allclocks or if the new device ATPIC is not present within the i386 kernel config (atrtc is linked to atpic presence).

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 support for XBOX to the FreeBSD port. The xbox architecture is nearly identical to wintel/ia32, with a couple of tweaks. Since it is so similar to ia32, it is optionally added to a i386 kernel. This port is preliminary, but seems to work well. Further improvements will improve the interaction with syscons(4), port Linux nforce driver and future versions of the xbox. This supports the 64MB and 128MB boxes. You'll need the most recent CVS version of Cromwell (the Linux BIOS for the XBOX) to boot. Rink will be maintaining this port, and is interested in feedback. He's setup a website http://xbox-bsd.nl to report the latest developments. Any silly mistakes are my fault. Submitted by: Rink P.W. Springer rink at stack dot nl and Ed Schouten ed at fxq dot nl

hyperv: Fix vmbus after the i386 4/4 split The vmbus ISR needs to live in a trampoline. Dynamically allocating a trampoline at driver initialization time poses some difficulties due to the fact that the KENTER macro assumes that the offset relative to tramp_idleptd is fixed at static link time. Another problem is that native_lapic_ipi_alloc() uses setidt(), which assumes a fixed trampoline offset. Rather than fight this, move the Hyper-V ISR to i386/exception.s. Add a new HYPERV kernel option to make this optional, and configure it by default on i386. This is sufficient to make use of vmbus(4) after the 4/4 split. Note that vmbus cannot be loaded dynamically and both the HYPERV option and device must be configured together. I think this is not too onerous a requirement, since vmbus(4) was previously non-functional.

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

x86: Add MPTABLE_LINUX_BUG_COMPAT option Linux has two bugs in its handling of the x86 MP table: 1. It assumes that there is always 640 kB of base memory, and looks for the MP table in the top kB of this even if the memory map indicates that memory location does not exist. 2. It ignores that entry_count field and instead iterates through the MP table by scanning until it runs out of bytes in the table. The Firecracker VM (and probably other related VMs) relies on both of these bugs. With the MPTABLE_LINUX_BUG_COMPAT option, we search for the MP table at address 639k even if that isn't in the memory map; and replace a zeroed entry_count with a value computed from scanning the table until we run out of table bytes.
