files of all the different powerpc ports (except amigappc). It should be
compatible with sandpoint and macppc. It is compatible with evbppc minus
one device (gtmpsc).
To convert a port to use this file rather than a local one, delete your
majors file, and edit your files.port to point to this instead. (I will
follow up with a MAKEDEV fix to support this)
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.
TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.
NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
an overflow occurs.
. Make this error a fatal build time error
. Move the support for dbsym into the MI Makefile.kern.inc,
conditional upon the SYMTAB_SPACE option being defined in
the kernel config file.
It cannot be compiled with -Wno-cast-qual due to a volatile pointer
being passed to memset(), and there's no easy way other than open-
coding memset() to fix this. So instead we cheat for now and add
-Wno-cast-qual to CFLAGS for this file. To be documented in doc/HACKS.
This makes it possible to define header files on the command line that
might include ${MACHINE} somewhere in the path. This might be used in
evbppc, for example, when defining PPC_PCI_MACHDEP_IMPL as, for example:
PPC_PCI_MACHDEP_IMPL="<arch/evbppc/sandpoint/pci_machdep.h>"
which will be included as
#include PPC_PCI_MACHDEP_IMPL
Prior to this change, the compile would fail trying to include
<arch/evbppc/1/pci_machdep.h>
the canonical versions in kern_synch.c). Define __HAVE_BIGENDIAN_BITOPS
so the canonical versions will be used but will store priorities in the
desired (MSB) order for PowerPC (which allows the use of the cntlzw (count
leading zeroes, word) instruction in locore_subr.S to find the proper
priority).
- different set of device control registers.
- non-standard access to the time base.
- 16 byte cache lines.

a pointer to current cpu's cpu_info structure. Use cpu_info for
intstk,intr_depth,still_stk,idle_pcb,curpcb,curlwp,etal even on
non-MULTIPROCESSOR machines. Add common macros GET_CPUINFO and
INIT_CPUINFO to get and initialize the cpu_info struct on startup. Make
ibm4xx use the standard <powerpc/frame.h>. Use IFRAME_xx in ibm4xx
trap_subr.S instead of explicit magic offsets. Move INTSTK and SPILLSTK
to std.<platform>. Change faultbuf to a struct instead of an array.
On MPC6XX cpus, stop using the vector page for temporary space and use
reserved space in cpu_info.
