Hot-Adding Nehalem Sockets on Solaris

Intel® QuickPath Architecture Performance
- Hot plug capability to support hot plugging of nodes, such as processor cards.
As Intel's engagement in the OpenSolaris community has continued, the first step toward readying Solaris for the hot-add capabilities of Nehalem hits build 123. This first round of changes lay down the ACPI infrastructure future phases of support will rely upon. Kudos out to Gerry Liu at Intel for getting the code into OpenSolaris. Places to get more details:
- PSARC/2009/104 Hot-Plug Support for ACPI-based Systems
- 6846944Device tree creation and acpi virtual nexus driver for acpi based x86 systems
- 6849408 Device matching rule in ppm.conf is not flexible enough
And of course me in my FMA world will get more excited as Solaris continues to be able to fault manage newly added resources. More to come on that I'm sure...
