printing into a function, add a bit more pretty-printing of existing stuff.
Implement pretty-printers for type 1 and type 2 headers. (Right now,
these are just quick stabs based on some on-line bridge docs that I have
handy on my laptop. Mmmm, meetings. I'll check the bits when I get
back within reach of my official docs.)
lots of data, e.g. ~18k on a PCI system with few add-in devices; use
with MSGBUFSIZE=...). Useful to have here so that people who want as
much data about the PCI configuration in a machine can get it without
having to craft their own code. Also, clean up a few of the other
#if 0'd printfs.
* print all configuration space registers. Then, where possible,
interpret them. (That is, PRESENT ALL THE DATA, then interpret it --
don't hide data behind interpretation. Also, when interpreting
fields, try to print out the specific value that's being interpreted.)
* handle different header types.
* allow caller to specify a function which can interpret the
device-dependent header and is responsible for pretty-printing it.
It spews (use 'options MSGBUFSIZE=...' 8-), but when you want the data,
you really want _all_ of it.
Still needs some cleanup and additional code (e.g. interepretation
of PCI-PCI (type 1) and PCI-Cardbus (type 2(?)) bridge headers).
pci_mapreg_info() call. pci_mapreg_map() implies this check,
but code which calls pci_mapreg_info() has to check it explicitly.
Otherwise, if memory space is disabled, the driver does the wrong
thing, and tries to use memory space anyway, potentially resulting
incorrect driver operation and no useful error message.
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
needs some testing, but it seems to produce sound. The driver was written
by me, but since I don't have the hardware the debugging and testing was
done by Andreas Gustafsson <gson@araneus.fi>, Chuck Cranor
<chuck@maria.wustl.edu>, and Phil Nelson <phil@cs.wwu.edu>. Thanks.
