Forced commit to provide a more meaningful commit message.
John Michael-Gurney is responsible for fixing all the vast majority of the
issues that arose with PCI support.
Kris Kennaway and John Birrell pushed heavily on stability issues. Kris is to
thank for it having even reached its current level of stability. When it
reaches a production state, we will have John to thank for driving it forward.
The following items are needed before sun4v can be used from CVS:
- binutils/gas/config/tc-sparc.c needs to be pulled in from a modern
version of binutils.
- an updated version of the loader needs to be pulled in from perforce
The following items need to be addressed before sun4v can be considered for
deployment:
- The T1 has a fairly minimal floating point unit, fsqrt and a number of
other opcodes are not implemented. Emulation for unimplemented opcodes
needs to be added.
- Running against local disk a race condition exists whereby a cpu will
sometimes run off into the weeds at tl > 2.
- The MD code for interrupt handling will crash on the first ATA interrupt.
- The BCM chipset (bge) is not set up correctly on the T1000. The current
workaround is to use an add in Intel GigE card (em).
- With KSE in the kernel signals are often not directed to the right
process / thread within a process. This causes threaded processes
to frequently become unkillable and gdb to not be reliable when debugging
a threaded process. This issue is slowly being resolved on -threads.
Many thanks go to Sun for having lent / donated a T2000 to both me and
John Birrell.
