In 32-bit mode, "xor eax,eax" is shorter than "xor ax,ax"

2007-11-10T00:56:02+00:00

For 32-bit code, 32-bit operations are shorter than 16-bit operations,
so use them.

Typo cleanup

Clean up the transition to PM for shuffle-and-boot-to-PM

2007-11-07T01:15:13+00:00

Clean up the transition to PM for shuffle-and-boot-to-PM, and set LDTR
and TR to keep Intel VT happy.

Setting cr0 requires a jmp to synchronize on 386/486

2007-11-05T00:34:38+00:00

The 386 and 486 requires a jmp after any setting of cr0.  It can be a
near jmp, but those processors do not correctly synchronize without
it.

We have jmps after setting cr0 in all spots except one, so make that
happen correctly.

Code cleanup: get rid of hard-coded descriptor numbers

2007-11-02T01:25:10+00:00

Get rid of hard-coded descriptor numbers, and instead use symbolic
names for the descriptors derived from the calculated offset in the
GDT.

Mark TSS unbusy before protected mode entry

2007-10-11T22:01:32+00:00

The LTR instruction marks the TSS descriptor busy, and any subsequent
attempt to load it will #GP unless maked unbusy first.  Sigh.

Set TR and LDTR when entering protected mode

2007-10-11T21:47:23+00:00

Intel's VT daftly requires TR and LDTR to have valid protected-mode
values in order to kick in.  Thus, give it at least a valid chunk of
memory for the TR and a null selector for the LDTR.

Support chaining shuffle descriptors when buffer is too small

2007-03-30T20:33:47+00:00

Provide a method for re-loading shuffle descriptors from a buffer in
high memory when the shuffle descriptors are too many to fit in the
buffer.  This can happen when trying to stitch an initramfs together
from parts.  Still need library support for this, however.

Stealth whitespace cleanup (automated)
