Calculate a LegacyRamSize directly from the e820 map for use by
handle_1588() and handle_15e801() (the only two external interfaces
that require "RamSize"). All other users of the existing RamSize (and
RamSizeOver4G) variables are specific to QEMU, so move the
declarations to paravirt.c.

CONFIG_QEMU means compile to start from QEMU (and possibly
Xen/KVM/Bochs) and definitely running under QEMU (or Xen/KVM/Bochs).
CONFIG_COREBOOT means compile for coreboot and definitely running
under coreboot. Places that used CONFIG_COREBOOT to mean "running on
real hardware" have been changed to use !CONFIG_QEMU.
CONFIG_QEMU_HARDWARE enables support for some virtual hardware devices
even if QEMU didn't start SeaBIOS.
usingXen() is replaced by runningOnXen().
runningOnQEMU() is added to hardware devices that are only safe to
access when we are sure we are running under QEMU (or Xen/KVM/Bochs).
Neither the coreboot nor the csm code currently enable runningOnQEMU,
but future patches may.

Set up the UC area of mtrr dynamically based on mtrr_base. This allows
the bios to work for other chipsets that might want to set the mtrr.
Since BUILD_MAX_HIGHMEM is no longer used we can remove the config parameter.
This change reverses the order of pci_setup() and smm_init() with
mtrr_setup().

Clean up includes of biosvar.h.
Rename GET/SET_EBDA2 to GET/SET_EBDA - nearly all users use the
extended form now anyway.

Enable SeaBIOS to work on 386/486 machines that don't have CPUID
instruction.
Based on patch by Rudolf Marek.

SeaBIOS is called by Xen's hvmloader which does the basic platform
setup (PCI, APIC, etc) and provides the various BIOS tables. Therefore
avoid re-doing that setup and copy out the tables as necessary. A
simple data structure is defined to pass the addresses of these
tables.
This patch also establishes the basic infrastructure to make
hypercalls, although it currently only uses it to query the hypervisor
version.

Some versions of Bochs don't like the MTRR initialization, so add
CONFIG_MTRR_INIT to control whether SeaBIOS will touch the MTRRs.
|
|
Use the "write protect" setting instead of "uncached" for that region.
Also, make sure to clear all variable MTRRs before enabling them.

Rename smpdetect.c to smp.c - the code does more than just cpu detection.
Don't probe cpu count on demand - schedule it during post.
Add logic to run wrmsr on all cpus.
Don't make mtrr setup specific to kvm - do it on all machines that
have mtrr and msrs.
Detect cpu signature/features automatically in mptable.
Also, make sure acpi structures are packed.
|
|
Use consistent types in mtrr.c.
Remove extra ';' from lds files.
Report found serial and lpt ports.
Remove extra newlines from inline asm.
Add memset_far and memset16_far functions.

Change license of contributions from Kevin O'Connor from GPLv3 to
LGPLv3 (or later). Since the work as a whole is based on Kevin's
contributions and the "bochs bios" which has a license of LGPL (v2 or
later), this effectively makes the work as a whole available under
LGPLv3 (or later).

Add some of the enhancements KVM has to their bochs bios tree. This
is only partial support for KVM - some features still do not work
correctly.
