1. Reduce debugging level to sane levels
2. Fix bugs in alloc_data_map related to allocing whole bytes of bitmap at
a time.
At this point the driver is functional. It talks to a local drive here and
can label/newfs. Performance is...lacking at the moment as its chewing cpu
heavily (probably due to the number of memcpy's) and will be the next area
attacked.
To make this work, we now have to use separate handler lists for hardware
and software interrupts as the soft interrupt handlers do not return
an `interrupt handled' status.
Thanks to Matt Fredette for providing an initial set of patches on port-sparc.
the same method to access TOD clock, so move chipset-dependent mcclock
routines to appropriate files.
This should also fix Express RISCserver and RISCserver2200 (aka R96) support
which has been broken since "struct platform" was introduced.
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
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.
