core: pass the file flags down through the stack

2011-05-02T01:11:40+00:00

Pass the file flags down through the stack.  This allows us to
distinguish between open for read, open for write, or opendir in the
low-level filesystem functions; this will matter for the PXE methods.

Generalize ipappend handling as "sysappend", and move to PM code

2011-04-26T03:25:02+00:00

Generalize the ipappend handling to cover all the derivatives, and
rename it "sysappend" ("ipappend" is a valid alias for all
derivatives.)  Move all the string handling to protected mode.
Currently only pxelinux exports strings, but the plan is to change
that in the future.

core: add a ms-denominated timer

2010-07-05T22:41:36+00:00

Add a timer denominated in milliseconds.  This is still driven by the
18.2 Hz timer interrupt, but counts "real" milliseconds, including
handing the adjustment factor (which in reality means it advances by
55 for most timer ticks and 54 for some.)

PM getcwd(); Fix COM32 getcwd

2010-06-27T03:52:58+00:00

Implement getcwd() in the core; Fix COM32 getcwd() to use the new function.

This resolves the previous comment about COM32 getcwd() not working by
not using INT 22h AX=001Fh.

Fix COM32 chdir()

2010-06-26T19:31:28+00:00

Fix COM32 chdir() since it's implemented in the core.
Forgot the core changes needed for this before.

pmapi: make the pmapi vector include its own size

2010-06-26T19:30:13+00:00

Future-proof the pmapi vector by making it include its own size.

core: move idle handling into protected mode

2010-03-30T23:10:13+00:00

Do the actual idling in protected mode.  This both allows PM code a
more efficient interface, but also handles bugs in HVM implementations
which don't handle HLT in real mode.

Add 32-bit versions of open file/close file

2010-03-06T19:55:57+00:00

Add 32-bit API calls for open file and close file.

readdir: replace opendir/readdir/closedir API with a 32-bit API

2010-03-05T06:54:07+00:00

The 16-bit API to opendir/readdir/closedir was confused, had a memory
leak, and was incompatible with Syslinux 3.x anyway.  Replace it with
a pure 32-bit API.

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.
