settings/drivers/kernel: Reorder to be in more logical groupings.

Also add better descriptions for APM and ACPI.

settings/drivers/kernel: Clean up and clarify comments.

No "functional" change.

data: Kernel settings file

* Add example line to always boot using safe
video mode (vesa)

Removing the acpi_avoid_full_init config option.

I've never heard anyone that been helped by that setting.

I was being lazy, as pointe out by mmlr. It is much better to copy DSDT always do you don't need to figure out if you need to toggle that switch.

Patch by scgtrp (Mike Smith) to copy DSDT to memory, as some machines corrupt DSDT after boot. This fixes bug #8043.

Forgot to commit that when enabling IO-APICs by default. It's the (commented)
kernel settings file entry to disable IO-APICs.

* Set the actual default of the ACPI module to enabled instead of relying on the
kernel settings file. As pointed out by Rene, there's otherwise no way to
enable ACPI when the settings file is absent, as there's only a disable switch
in the boot menu.
* Remove MADT dumping as it isn't really implemented. This info can actually be
printed in the IO-APIC code now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41497 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add commented setting to enable the laplink type debugging output module.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39998 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added safe mode option B_SAFEMODE_4_GB_MEMORY_LIMIT (plus a boot loader menu
item) and kernel settings option "4gb_memory_limit". Enabling either one
causes the memory beyond 4 GB to be ignored.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37225 a95241bf-73f2-0310-859d-f6bbb57e9c96

Enable ACPI.

While there has been no reports of fan or temperature problems that we know of,
there are rumours that this might happen.
It's a good idea to check that fans and temperature works as normal
just to be safe.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36474 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented TODO about not loading symbols at boot.
This saves ~0.5s of boot time here, but I suspect it might be better for CD.
Enabled loadSymbols in kernel settings so the behavior should be the same as before this change.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34666 a95241bf-73f2-0310-859d-f6bbb57e9c96

patch from Fredrik Holmqvist:
* oshaiku.c is based on a different original from a stub, therefore it
looks like a lot of comment changes.
* achaiku.h is redone completely.
* dpc is added as boot module.
* acpi_busman.c now does all mandatory steps to init.
* style fixes
* added another acpi kernel settings to avoid full init for debugging.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33236 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added an emergency key mechanism to the kernel, inspired by Jan Klötzke's
patch from about a year ago (I couldn't use any code of his yet, though,
but there are a few things left). The emergency keys are triggered by
pressing Alt-SysReq + key.
* By default, only Alt-SysReq+'d' is used as a means to deliberately enter
the kernel debugger. F12 belongs to userland again, now :-)
* Debugger add-ons now have another optional method to implement their own
emergency keys - 'd' for the debugger cannot be overridden, though.
* The mechanism can be turned off via a new kernel setting, so it's not that
easy anymore to "crash" Haiku if you don't want to.
* Right now, the PS/2 driver, and the pre-input_server in-kernel debugger
keyboard mini-driver support this, USB not yet.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31660 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a new kernel setting "syslog_buffer_size" to change the size of the
internal syslog ring buffer.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28280 a95241bf-73f2-0310-859d-f6bbb57e9c96

Update example description to the current state of affairs. Please revert to old description whenever we enable ACPI by default again.

When the boot loader goes to load its settings files, it will now also prepend the "kernel" settings file to the safe mode settings if it exists. This allows settings from kernel/drivers/kernel to be respected early in the boot process as well, which allows us to do things like disable_smp permanently instead of having to pick from the safe mode menu every single boot. Review welcome.

Enabled syslog debug output by default, added new syslog options to config file.
Reversed arguments in kernel settings file, now you only need to uncomment a line
to get the non-default setting. Explained default setting in comments.

on at least one of my systems, it only works on 3 of them...).
