we start calling into C code. Previously we called memset() in our
C code. Unfortunately the compiler would sometimes store local variables
on the statck, which got killed by the memset(). Oops!
0x6?0000, load at 0xe00000. This gives us room for around 13 MB of
kernel, as opposed to the current 5 MB (0x600000 - 0x100000).
No changes to load-base or real-base are needed due to this change,
though machines that needed specific OFW settings before (OF 1.x
and 2.x) this change still need those settings.
Partially revert revision 1.25 -> 1.26 of ofwboot/Makefile & friends.
We do not need to distinguish between where ofwboot and ofwboot.{elf,xcf}
load; they are both fine loading somewhere other than load-base.
* lpt device is defined in MI place (dev/ppbus/files.ppbus), dev/ic/lpt.c
is included there too; dev/ic/lpt.c is not included if ppbus is
configured or if there is alternative platform lpt (like for pc532)
* g/c MD lpt definitions and custom puc/upc attachments,
glue moved to conf/files and dev/pci/files.pci respectively; remove
device lpt definition from dev/isa/files.isa
* add ppbus parport attribute, atppc device attachments, adjust plip and lpt
glue
files for machines I know to have genuine PCI slots. As sent to tech-kern
for feedback in December 2003. Based on feedback, opencrypto is commented
out in the macppc GENERIC (due to absense of GENERIC_SOFTINT support),
and added to the sparc64 config (sys/arch/sparc64/conf/GENERIC32).
- wdc_xfer to ata_xfer
- channel_queue to ata_queue
and move them to <dev/ata/atavar.h> so they can be used by non-wdc ATA
controllers. Clean up the member names of these structures while at it.
some iBook and PowerBook models.
this driver was written by Tsubai Masanari and further hacked on by
Jared D. McNeill to work on his iBook.
the driver is limited (master volume control only, and I haven't
tested recording) but has been functioning perfectly on my PowerBook
g4 DVI (ivory) for some time.
ok'd by matt.
APs to run at "full speed" where before they ran at just 1 or 2Mb/s.
The AP will adapt the data rate for each client based on packet
losses and the received signal strength.
I have also enabled rate adaptation for STA mode and for IBSS mode,
but the hardware gives us less control over the data rate in those
modes.
copyin() or copyout().
uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed. however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors. most of
the callers of uvm_useracc() make the above incorrect assumption. the
rest are all misguided optimizations, which optimize for the case
where an operation will fail. we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors. since there appear to be no good uses of uvm_useracc(), we'll
just remove it.
While we are here, try to tag machine dependent functions in header files.
also transformed darwin_ppc_*_state into mach_ppc_*_state, as this is
what they really are (COMPAT_DARWIN is on the top of COMPAT_MACH, not the
other way around)
Use <powerpc/oea/bat.h> exclusively and remove <machine/bat.h> and
<powerpc/bat.h>. Remove unneeded <machine/cpufunc.h>. To insure
1:1 correspondence of <powerpc/FOO.h> to <machine/FOO.h> include
"../../powerpc/include/Makefile" in "arch/FOO/include/Makefile".
Incororpate <byte_swap.h> into <bswap.h> and then byte_swap.h
