Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

compiled with gcc and linked into the hvmloader as a byte-array.
Hvmloader allocates memory (rounded up to next 64kb) from the e820
table
below 4GB, copies and relocates the 32bit code in the allocated area
and
copies a jumptable (located in a section '.biosjumptable') pointing to
the 'exported' functions into the Bochs BIOS's memory area to link the
two code sections. The memory area has been reserved and can be
identified with the signature '___JMPT'.
In the Bochs BIOS only stub functions are provided. These load the
index
of a particular function in the jump table, switch to protected mode
and
call the function in the high memory area. The stack is prepared such
that functions compiled by gcc can just pick the parameters from the
stack as usual - this means that the 16bit real-mode return address is
taken off the stack. The stub functions should have the same signature
as those in 32bit space. For ABI compatibility reasons parameters
inside
the Bochs BIOS stubs should all be 32bit wide.
This patch includes a test function that calls three gcc-compiled
functions in the high memory area and displays their success status.
Simple tests are done doing multiplication and addition of 32-bit
numbers and reading and modification of a static variable. These
functions test the interface and the relocation code. The test code is
removed in patch part 3.

Currently the ROMBIOS includes static MP tables for only four
configurations: 1-way, 2-way, 4-way, and 8-way.
This patch makes the creation of MP tables more dynamic by creating them
from within HVMLOADER based upon the VCPU number provided by the HVM
information table.
Note: Some of the information included used to create the MP tables is
still hard coded and based upon values used in the original ROMBIOS MP
tables. Data such as the CPU family/model/stepping information should
probably be made to match the information provided to the guest when
executing a CPUID.

Advertising more CPUs than the guest is allocated hangs boot
of Windows XP (selects wrong HAL). The correct fix here is
to dynamically generate the MPS table (at least the CPU
entries) from hvmloader binary.

* Move .PHONY directives next to targets,
this makes them a lot harder to miss
* Add missing .PHONY directives
* Remove nonexistent .PHONY directives
* Hopefully I didn'T miss anything...

The following allows you to run unmodified guest operating systems
under Xen on VMX (VT) enabled processors. The tree lives under
<ROOT>/tools/dfw. Instead of booting a guest kernel, boot vmxloader and
specify the disk image in qemurc.
