com32: replace hard-coded bounce buffer use in com32/lib

2010-02-24T22:18:49+00:00

Replace hard-coded bounce buffer uses in com32/lib with lmalloc/lfree.

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.

lmalloc: set errno on failure

2010-02-24T19:58:42+00:00

The core function can't set the com32 errno, so we need to do it in
the wrapper.

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.

pxe: clean up/fix generation of ipappend strings

2010-02-24T03:35:11+00:00

Clean up and fix the generation of the ipappend strings.  In
particular, BOOTIF= was generated into a buffer which was too small.
Put the buffer definitions in C while we're at it.

fs/pxe: drop the use of PKTBUF_SEG

2010-02-24T03:16:34+00:00

Drop the use of a magic PKTBUF_SEG, and instead just have a high
memory buffer for each file, and a single lowmem buffer that we reuse
at will.
