SV stuff to be committed to FreeBSD
Revisit these as we port to 8.1.
TSC miscalibration
- reqst00084792
- Supermicro / SMM / BIOS related
- Files in 6.x:
- sys/i386/isa/clock.c
- sys/i386/include/clock.h
- sys/i386/i386/tsc.c
- sys/amd64/isa/clock.c
- sys/amd64/include/clock.h
- sys/amd64/amd64/tsc.c
- Merged x86 tree
- sys/x86/isa/clock.c
- clock.h not moved - why?
- tsc.c not moved
- gnn confirms still an issue on 8
- Addressed by mav's patches in HEAD
- MFC to 8 in progress
Softclock backlog printout after panic
- sys/kern/kern_clock.c
- sys/kern/kern_timeout.c
- sys/sys/callout.h
if_bridge changes
Interfaces for querying the state of an if_bridge interface’s MAC learning table.
- fw-bsd/src/sys/net/if_bridge.c
- fw-bsd/src/sys/net/if_bridgevar.h
vlan routing socket notification
Notify the routing socket if the configuration of a vlan interface changes.
- fw-bsd/src/sys/net/if_vlan.c
- fw-bsd/src/sys/net/route.h
- fw-bsd/src/sys/net/rtsock.c
dummynet
Change RED_SCALE from 16 to 12. RED_SCALE is a scaling parameter that's used in dummynet's implementation of the RED algorithm.
- fw-bsd/src/sys/netinet/ip_dummynet.h
Interface renames
Add IFAN_RENAME define for interface renames. In discussion with brooks@ (the original author of interface rename support in FreeBSD) this is the approach we'll take upstream, but probably with a backwards compatibility mode there.
- fw-bsd/src/sys/net/if.c
- fw-bsd/src/sys/net/if.h
Others
- top & libthr - print thread names in top
- Contribute from $WORKBSD
- sysctl_handle_byte
- We use to expose some if_em registers
- em(4) rxd / txd tunables
- don't recall exactly what this was
- maybe just need to contribute something from $WORKBSD
- descriptor ring sizes?
- Read-only .text section
- sys/kern/kern_linker.c
