input files should not be .o; from Scott Cheloha

Split early startup code out of locore.S into locore0.S. Adjust link
run so that this locore0.o is always at the start of the executable.
But randomize the link order of all other .o files in the kernel, so
that their exec/rodata/data/bss segments land all over the place.

As a result, the internal layout of every newly build bsd kernel is
different from past kernels. Internal relative offsets are not known
to an outside attacker. The only known offsets are in the startup code
(which will be gone when it is smashed).

The bootstrap code unmapping or smashing isn't done yet, and there is
some potential for more bits from locore.S to move to locore0.S

Since we are no longer attaching radeondrm(4) to this driver there is
no reason to pretend being compatible with the MI vga layer. So stop
using the vga_pci_bar interface and reduce the differences with the
sparc64 driver.

Include files.agp and files.drm from files.pci. Makes sure "drm.h" gets
generated on all architectures that support pci, making alpha and loongson
compile again.

ok todd@, miod@ seemed to agree with the idea

radeondrm now attaches directly to pci.

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

Thanks to M:Tier and the OpenBSD Foundation for sponsoring this work.

Mimic what's done on sparc64 and parse the OpenFirmware device tree to

Add sysbutton a driver for the 'System identifier' button found on the

and you press and hold the button you will cause a interrupt storm that will
slow the system down. So if you keep your xserve near a toddler or you

The "powerpc" port which has supported the newer Apple Macintosh powerpc based

between different powerpc base platforms.

Most of the work involved in the renaming process was performed by miod@

Files moved from powerpc/conf to macppc/conf

files.powerpc was modified to keep powerpc common files.

input files should not be .o; from Scott Cheloha

Split early startup code out of locore.S into locore0.S. Adjust link
run so that this locore0.o is always at the start of the executable.
But randomize the link order of all other .o files in the kernel, so
that their exec/rodata/data/bss segments land all over the place.

As a result, the internal layout of every newly build bsd kernel is
different from past kernels. Internal relative offsets are not known
to an outside attacker. The only known offsets are in the startup code
(which will be gone when it is smashed).

The bootstrap code unmapping or smashing isn't done yet, and there is
some potential for more bits from locore.S to move to locore0.S

Add a thermal management framework for macppc which controls the fan speed
