manage interrupt masking.
This change is necessary for straightforward implementation of coming IPL
support for cascaded intrs, and it should not impair performance.
swap in and out the mappings for virtual pages zero through three,
which are what the PROM really uses. This is tied to the
move to ELF and the low memory usage changes.
now loads the kernel into physical memory at the linked address.
So we link the kernel a little lower virtually, but the bootloader
actually will load it higher in physical memory than before.
This allows us to quadruple the size of the msgbuf to 8K, and
we also shuffle around tmp_vpages and the temporary stack.
Added % to all register names. The boot loader now
loads us exactly where we're linked, so no PIC or
remapping funny business. Removed more 68881 code
that is only needed with the real silicon, which
a 68010 will never have.
define what "boot media" and "distribution media" mean
macppc/install:
corrected the text in example of booting system
corrected partition number to use in example of booting from HFS partition
added example of how to use MacOS X to print partition table using pdisk
macppc/prep:
actually drive setup 1.8.1 (ships with MacOS 9.0) works too
actually describe what netbsd.ram.gz is (installation kernel)
common/postinstall:
macppc uses vt100 for console, not vt220
describe how to mount root filesystem to edit /etc/rc.conf
order of recommendations for installation methods.
macppc/hardware:
update list of unsupported models
macppc/prep:
mention that ofwboot.elf is obsoleted, and all users should be using
ofwboot.xcf instead
link to partitioning HOW-TO on website
added some info on the "official" NetBSD/macppc-1.5.1 CD-R image
added some info on cdrecord
added note that netboot must be from on-board ethernet
macppc/install:
added a few more details to some of the open firmware error messages
reordered error messages to be in order user might encounter them
removed "pciide0:0:0: lost interrupt" since this is fixed in 1.5.1
added "TFTP timeout" and explanation to list of possible problems
point to macppc X11R6 HOW-TO
common/postinstall:
point to macppc X11R6 HOW-TO
common/xfer:
recommend waiting until later to create media for distribution sets
common/sysinst:
control-C to stop sysint, but added that you can re-run it from the
command prompt, no need to reboot.
added an example of what the sysinst main menu looks like
timezone in the kernel. We now keep track of it for emulated processes.
Tested for powerpc and i386. Untested on m68k, but it should be ok
Alpha has a particular implementation (osf1_sys_gettimeofday), and it has
therefore not been touched.
DIAGNOSTIC/DEBUG from the kernel. This helped to boost the performance
on my test machine from ~5KB/s to like 800KB/s for ftp test, and
to like 700KB/s for netio test. I wouldn't have imagined the options
are THAT costly ....
I guess he indents to prepare a temporary variable for saving the next
pointer of a list element, but he seems to forget to substitute the
pointer for the variable. This often causes my dreamcast panic.
Previously, we passed __FILE__ and __LINE__ on all pool_get/pool_set calls.
This change results in a measured 1.2% performance improvement in
ping-flood packets-per-second as reported by ping(8).
