useful. The functions delay, cpu_initclocks, and setstatclcokrate have been
renamed to mips3_delay, mips3_initclocks, and mips3_setstatclockrate.
We provide weak aliases for the original names, so machdep code doesn't have
to provide wrapper routines. (Giving good performance.)
I've moved mips3_clockintr, mips3_initclocks, and mips3_setstatclockrate to
their own mips3_clockintr file, because some ports may not be able to use
these, and its senseless to carry that baggage.
- Add a few scopes to the kernel: system, network, and machdep.
- Add a few more actions/sub-actions (requests), and start using them as
opposed to the KAUTH_GENERIC_ISSUSER place-holders.
- Introduce a basic set of listeners that implement our "traditional"
security model, called "bsd44". This is the default (and only) model we
have at the moment.
- Update all relevant documentation.
- Add some code and docs to help folks who want to actually use this stuff:
* There's a sample overlay model, sitting on-top of "bsd44", for
fast experimenting with tweaking just a subset of an existing model.
This is pretty cool because it's *really* straightforward to do stuff
you had to use ugly hacks for until now...
* And of course, documentation describing how to do the above for quick
reference, including code samples.
All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:
http://kauth.linbsd.org/kauthwiki
NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:
- Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
- Checks 'securelevel' directly,
- Checks a uid/gid directly.
(or if you feel you have to, contact me first)
This is still work in progress; It's far from being done, but now it'll
be a lot easier.

Many thanks to YAMAMOTO Takashi, Matt Thomas, and Christos Zoulas for help
stablizing kauth(9).
Full credit for the regression tests, making sure these changes didn't break
anything, goes to Matt Fleming and Jaime Fournier.
Happy birthday Randi! :)
on port-ews4800mips.
XXX: ews4800mips can't use mips/mips/mips3_clock.c for now because
it isn't configured to use internal clock interrupt for CPU INT 5,
i.e. mips3_clockintr() is not needed and its own cpu_initclocks(9)
is required.
long standing issue with interrupts onthe PowerStack E1. Remove the
quirk entry for the PowerStack E1 and revert to using the IVR.
Also, add a \n to the attachment of the mk clock printf that was missing.
From the PR:
The cache is flushed using the bus address where the phys address
is required. Errors would be seen only on ports where address
translation is done between the bus and physical memory.
The PIOBM is used by only one driver (will be added later,
stay tuned) and intruduce an attribute "ata_piobm" so that
it will be conditionally compiled in.
The "ata_dma" (busmastering transfer using ATA DMA mode) and
"ata_udma" (busmastering transfer using ATA Ultra DMA mode)
attributes are also added for consistency, but unused for now.
Convert to timecounters.
From Rivo Nurges (rix at estpak dot ee). ok soren@, tested by simon@.
Note that this means we aren't using the gt clock, and maybe we should clean
that up a bit.
by the initial PCI_NETBSD_CONFIGURE, nor should it be manually wired by
the indirect stuff. This is all taken care of by the prep_init() function.
7025-F40 support supports the primary pci bus only. The second PCI bus
on the machine is still unsupported, but the machine runs and can access
everything except for the two slots the other bus covers.
We can have in a register an address that points to/into some variable
in the data segment, but db_print_loc_and_inst only looks for
functions, so it will misprint it as something unrelated from libkern
+ huge offset. E.g. instead of netbsd:cpu_info_store it would print
netbsd:prop_string_create_cstring+0xdeadbeef
Worse, if the address happens to be odd (char field in a struct, an
element of char array), attempt at printing the "instruction" at that
address will cause a fault and will abort "mach frame".
Disassemly is not really that useful in "mach frame" listing anyway
and more often just clutters things by overflowing 80 columns.
Dreamcast does not use SuperH on-chip RTC, so do it seprately from
other sh3 ports. Convert dreamcast rtc code into a real device
instead of searching/attaching it manually.
