f7b963da51 (Redoing check-in lost by SourceForge's failure.) 
Use .text16.data section with "aw" attributes, to avoid section type
conflicts when placing both code and data into .text16.

Add __from_{text16,data16}.

fdb983d473 Preserve the whole of %esp across prot_call(). We have to split this 
between the low half stored in the static variable rm_sp, and the high
half stored on the prot_call() stack, because:

  Just using the stack would screw up when a prot_call()ed routine
  executes a real_call(); it would have no way to find the current top of
  the RM stack.

  Extending rm_sp to rm_esp would not be safe, because the guarantee that
  rm_sp must return to the correct value by the time an external
  real-mode call returns applies only to %sp, not to %esp.

f8e087767b Allow access to variables in .text16 as well as .data16. Chained 
interrupt vectors, for example, will be easiest to handle if placed in
.text16.

832807726a Add infrastructure to support access to .data16 (and .text16) variables 
from protected-mode code.

Set up %ds to point to .data16 in prot_to_real, so that code specified
via REAL_EXEC() and friends can access variables in .data16.

Move most real-mode librm variables from .text16 to .data16.
 2006-05-04 23:14:06 +00:00

f4429533a6 Added methods for efficiently declaring and accessing variables in 
.data16.  librm will need to supply "char *data16", i.e. the virtual
address of the start of .data16.

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.

10c28a51bd Create two easy-to-use entry points in libprefix: install and 
install_prealloc.  I *think* these will suffice for all the 16-bit
prefixes.

9e1dd6402d <name>_size variable is no longer needed, since we don't copy the code. 
However, it's worth adding a .size directive so that objdump reports the
correct sizes for the code fragments.

9fcded3d23 Towards a(nother) new real-mode infrastructure, in which we take 
advantage of the fact that we have to have a permanently-resident block
in base memory.

8f62b39c03 Move stack out to separate object, so that having a stack doesn't drag in 
setup.S.

d081d65d48 This should be much more elegant: we use flat real mode for the 
highmem data, so decompress16 will be able to unpack blocks bigger
than 64kB.

cc8821a443 Checking in because I don't want to lose this rather neat code for 
running the decompresser in 16:16 protected mode using the real-mode
stack.  However, there's an even simpler way to do it...

04b6a1e004 Make all TCP methods optional; at least FTP data is a read-only 
connection and so legitimately ignores acked() and senddata().

bac97eb979 Change semantics of network API so that packet-absorbing calls *always* 
take ownership of the packet, rather than doing so only if they return
success.  This breaks semantic compatibility with Linux's
hard_start_xmit() method, but means that we don't have to worry so much
about error cases.

Split mechanism of processing received packets (net_rx_process()) out
from policy (net_step()), preparatory to putting net_step() in a separate
object.

d8e99bf28f Gave up on adding POSIX errno's as required, and just added (almost) all 
of them in one go.

EBADIMG has been replaced by ENOEXEC, and EIMGRET by ECANCELED.
