syslinux.ld: remove redundant definition of STACK32_LEN

2010-06-27T03:37:37+00:00

STACK32_LEN is already defined in layout.inc.

syslinux.ld: don't pad between .got and .data

2010-05-13T04:22:14+00:00

Adding padding between .got and .data is unnecessary, and can
cause spurious decompression failures when .data is empty (which it
almost is already...)

core: don't bother zeroing the disk cache and heap

2010-03-07T05:44:42+00:00

No point in zeroing out the disk cache and the heap.  Put those in a
.hugebss section which we align, but don't zero.

core: page-align .earlybss

2010-03-07T05:30:56+00:00

Leave the entire first page unmolested.

core: use assembly for the .stack section

2010-03-07T05:29:47+00:00

Use assembly to define the .stack section, so that it get proper
attributes.

core: fix lowmem malloc

2010-02-24T22:16:15+00:00

a) initialize *all* the head nodes
b) the lowmem heap needs to be paragraph (16 byte) aligned
c) use a dedicated tag value for headnodes.  The type code should be
   removed and replaced with special tag values for head node and
   free.
d) for libcom32 code called from the core, do NOT present a
   usable bounce buffer; we should only ever use lmalloc/lfree.

core: move aligned segments earlier

2010-02-24T19:14:04+00:00

Move the aligned segments downward, to provide for the largest
possible contiguous lowmem heap.  This minimizes the necessary lowmem
footprint.  (Note: the heap doesn't actually need to be contiguous,
but having it not be makes it harder to size.)

core: use better malloc; add low memory malloc; fix com32 exit

2010-02-24T06:32:32+00:00

Use a better malloc for the core.  In particular, use the same core
that we should eventually be able to use for the entire system in
Syslinux 5 -- with module awareness, etc.

This code can also accommodate multiple heaps.  Set up a separate heap
for lowmem; the intent is to use explicit lowmem allocations instead
of the static bounce buffer.  The lowmem allocation is also exported
via the pmapi mechanism, so modules can safely allocate lowmem.

core: let xfer_buf_seg, real_mode_seg be assigned by the linker

2010-02-21T23:42:03+00:00

Use the linker to assign xfer_bug_seg and real_mode_seg.

core: separate bcopyxx code and data; use linker-generated symbols

2010-02-16T01:47:09+00:00

Separate out bcopyxx code and data, and use linker-generated barrier
symbols instead of inline label hacks.  This makes it possible to link
code into the bcopyxx area if need be.
