Thorpe as an extension to the bus_space(9) API.
Only the mainbus has a working mmap... iomd, podulebus and isa dont have
one yet. Its trivial to add the iomd and isa's memory part but am a bit
hessistant to add it without knowing its implications by heart.
Podulebus might be implemented in 32 bits EASI but otherwise its not really
transparent since there is AFAIK no function to explicitly read one byte or
so .. or is this implemented in a higher level ?
ARM26 and arch/arm32/dnard (Shark) kernels compile and RiscPC and Shark
kernels are tested and function OK.
Implications of other ARM systems like hpcarm and ebarm are propably
minimal or solved trivially.
functional yet since the keyboard changes are not committed yet but it
should compile and work independently.
Initial support for mouse and screen takeovers / screen hardware scroll
reset is done.
Improved locking (not that we actually use it on a uniprocessor, but one day :)
Removed unneeded splvm's
tweaked pmap_clean_page code to only flush the cache if the page is mapped in the current pmap (based on diff from richard E)
Adopted pv entry allocation mechanism from i386.
Laid framework for returning ptp's when we've finished with them rather than holding onto them till the process exits.
ptp's are now allocated with a uvm object for the pmap, means that we can walk a list to free them off in pmap_release, until they get freed off by pmap_remove.
Also implemented a page zeroing function when the processor is idling. Note that hpcarm may wish to disable this.
I believe this code to be stable, if anyone has any problems please shout up.
bootable GENERAL kernel for the 3 machines.
This is done by integrating the ARM7500 in a better way. In various places
the IOMD ID is checked and action is taken at runtime compared to
compiletime.
The small piece of assembler that is changed now uses the flag
`arm7500_ioc_found' that is set up by iomd.c at startup. When this chip
isnt found at startup it will skip reading the ARM7500 extended IRQ
registers and wont clear them either.
The next step will be getting the mode-definition files to the bootloader.
Currently they are compiled in.
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)
header file. This should allow MI drivers to use the podloader functions,
though obviously they'll have to be able to cope if podulebus_initloader()
fails.
ea0 at podulebus0 slot 2: address 00:02:07:dd:ee:16, 16-bit, SEEQ 8005
eb0 at podulebus0 [ netslot 0 ]: address 00:00:a4:54:42:cb, 16-bit, SEEQ 80C04
Netslots will be dealt with later (I didn't like the idea of just printing
"slot 8").
