Hi! I've been doing a little hp700 work lately. While I don't have a new
snapshot, I do have a small update that should address the problems people
were seeing with the last snapshot.
This tarball contains a new bootable LIF image, a new kernel, and a new
/usr/libexec/ld.elf_so, to replace those in the 2002-07-06 snapshot.
I've tested this on a 712/80, 715/50, and a 735/99. Highlights:
- No more BTLB entry waste. The kernel used to run out of BTLB entries
on a 712/80, which only has eight.
- Better pmap memory usage. The pmap used to consume a gratuitous
amount of memory for its data structures.
- A workaround for a still-misunderstood cache behavior has been added to
ld.elf_so. This lets dynamic executables work on a 735/99.
- "ie0: receive descriptors out of sync" are now rare. They still
happen, but not nearly as much as they did before.
- On many machines that have them, the network transmit, network receive,
and SCSI LEDs blink, and the load average is displayed on the "other" LEDs.
