d6866202f9 Until we have a functioning UDP stack and PXE API again, there's not much 
point trying to use the old boot sequence.  Replaced with a call to the
AoE demo code, so that people can at least build and try something useful.

0479e9f541 relocate.o is now dragged in by the objects that require it; there is no 
need for a CONFIG_RELOCATE.

bef8874842 - implemented printw (formatted string output, a la printf) 
- implemented hline/vline (part of wborder family)
- screen cursor now relocates at same time as window cursor when
  restoring after a non-wrapping function

84a493b88d Allow vcprintf() to be called by external code such as the curses library. 
Also trim another eight bytes from vsprintf.o.  :)

f778500739 - fixes to _wputch to get positioning and wrap working properly 
- fixes to wborder (same)
- addition of a few minor functions
 2006-05-22 13:10:19 +00:00

d166dc57ab - made _wputch wrap lines as well as cols (wraps back to line 0, as we have not way to scroll...) 
- implemented color_content, wborder, wblrtobot, wclrtoeol, wcolor_set and several small functions
- added rest of expected global variables

a4143e8c87 Split debug functions out into core/debug.c, so that they can be 
automatically linked in on demand.

Corrected warnings in misc.c.  strtoul() really should be
  unsigned long strtoul ( const char *p, const char **endp, int base )
but such is not the ANSI standard.

15ee09ed10 Restructured PCI subsystem to fit the new device model. 
Generic PCI code now handles 64-bit BARs correctly when setting
"membase"; drivers should need to call pci_bar_start() only if they want
to use BARs other than the first memory or I/O BAR.

Split rarely-used PCI functions out into pciextra.c.

Core PCI code is now 662 bytes (down from 1308 bytes in Etherboot 5.4).
284 bytes of this saving comes from the pci/pciextra split.

Cosmetic changes to lots of drivers (e.g. vendor_id->vendor in order to
match the names used in Linux).

0afa9db2de Tear out old heap code, replace with code that simply allocates memory 
for use by malloc().

This breaks the image-loading code (which previously used the heap to
allocate the buffer for downloading the image), but that's not a major
concern since I'm going to tear out all the image formats within the next
couple of days anyway.  Byebye, NBI!  :)

efd6281a35 Correctly handle zero-length buffers. 2006-05-14 11:18:42 +00:00
Michael Brown
25f5d114a0 Updated documentation. 
Shaved around 100 bytes off vsprintf.o.  It's now 50 bytes smaller than
the old implementation and provides much more conformant semantics,
including the ability to return the number of characters that would have
been printed to the string had the buffer been big enough.  (iSCSI needs
this functionality).

f99e7a375e At least cope with "%llx" by reading the correct-sized va_arg from the 
stack, even if we don't yet print it out.

At some point, vsprintf() needs to be fixed up so that it can correctly
cope with limited-sized buffers (i.e. vsnprintf), long longs, and
standard format specifiers (e.g. "%04x").  We should also remove the
special types (MAC addresses and IP addresses).  This would then enable
us to use gcc's ability to type-check printf format strings.

f8f75cef5b BSS is now zeroed by libprefix (along with the otherwise non-zeroable 
portions such as the stack) during the installation process.

init_fns() are called from main().  We need to think about initial
control flow some more.

95f8a42930 Removed incorrect comment; malloc() is inefficient only when the 
alignment and size are both powers of two, and there's no way to
specify an alignment through the malloc() interface anyway.

b601a7d355 Updated memory allocator to improve support for unaligned or partially 
aligned blocks.

Moved header to include/malloc.h, since we now also provide the
POSIX-like malloc()/free() pair.

Not yet tested.

832e86246b gcc is rather over-aggressive about optimising out static data structures 
even when __atribute__ (( unused )) is correctly set...

824d6ffa7f Header rearrangement. 
I want to get to the point where any header in include/ reflects a
standard user-level header (e.g. a POSIX header), while everything that's
specific to gPXE lives in include/gpxe/.  Headers that reflect a Linux
header (e.g. if_ether.h) should also be in include/gpxe/, with the same
name as the Linux header and, preferably, the same names used for the
definitions.

Michael Brown
49f933fbc3 Moved if_ether.h and if_arp.h to include/gpxe, for consistency with Linux 
kernel.

Removed obsolete struct arprequest from if_arp.h and put it in nic.c so
that nic.c will still compile.  ARP will very shortly be handled by
net/arp.c instead.

75d864432c Use the magic of common symbols to allow struct dev to effectively grow at 
link time to accommodate whatever bus objects are included.

1434e8d68d struct nic is now part of struct dev, rather than the other way around. 
Tie into new boot device framework.

out the new probing logic.

87508aa0b2 arch_initialise() is now sufficiently generic that we may as well just 
call it initialise() and place it in main.c.  :)

1937b39079 Drag in relocate unless NORELOCATE is defined, since it's now called 
only via the initialisation function table.

a4920c16bd Moved relocate.c to arch-specific dir, since it involves arch-specific 
logic (e.g. avoiding memory regions with A20=0).
