The first board to be included here is the port to the 405GP-based
Walnut evaluation board, which up until now lived in arch/walnut.
arch/walnut will go away soon, once all the remaining walnut-isms
in the tree have been dealt with.
support up to the max ohci descriptor segments. Then attempt to fill it in
via a load. Use the number of segments filled in as the basis for figuring
out how many descriptors to supply to the ohci DMA engine.
XXX: Still needs to account for requests which because of splits may overflow
the 6 dma descriptors available today. For now this fixes cases where a
single 512 byte write was getting split into 2 dma segments from 1 incoming
iov request
executed the make job with sigprocmask(SIG_BLOCK) in effect for a
number of signals including SIGCHLD. This caused recursive submakes
of the make process in question not to receive SIGCHLDs when their
jobs exited. This was a second, independent cause of bin/18895 in
addition to the race condition already fixed. Fixed by unblocking all
signals before executing the job.
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.
- The pcibus is now called 'pcib' and the isabus 'isab'. Their attributes are
'pcibus' and 'isabus' respectively. This makes the underlying busses
attach again.
- Initialize the parent structure in the config_console() function.
Otherwise we end up without a console.
given that PROM maps just 4 or 16 this is not going to be a bottle
neck). Doesn't really affect normal kernels, need it for the changed
kernel base address (uncommitted) hack for broken javastation OFW.
Ok by pk.
The definitions were not the same between the scsi_messages file and this
definition so simply removing it here and letting the other one be used
results in incorrect behavior (regardless of whether it made the code
compile....)
compat/common, so that they can be shared by several emulations, and use
them for Darwin.
This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN
