The integration of:
PSARC/2009/505 IRM Framework Extensions
PSARC/2009/665 Pcitool Extensions
6669984 Solaris x86 need to provide large number of interrupt
vectors for MSI/MSI-x
6866130 Interrupt Resource Management (IRM) support on x86 platforms
6876744 Need a new mdb debugger module for the new apx PSM
6881939 decouple current i86xpv interrupt implementation from i86pc
6916041 Pcitool Enhancement(1M) for the new apix PSM on X86
6957091 update pcitool(1m) manpage for 6916041
Introduces enhancements to the x86 platform specific interrupt framework
(apix) which provides large number of interrupts for MSI/MSI-X that scales
with the number of processors in the system. This is currently enabled for
Nehalem-EX based platforms and beyond. This project also enables IRM
(Interrupt Resource Management) feature for x86 platforms that depends
on the enhanced interrupt framework. This provides the following benefits:
* Configuration of large number of devices in the system.
* Device drivers can now get upto 8 MSI-X interrupts by default and
more if they are using IRM interfaces (ddi_cb_*register(9F)).
* Enhanced pcitool(1M) command with new options.
* IRM feature enabled for x86 on Nehalem-EX platforms.
Note that the new functionality is enabled only for Nehalem-EX
based systems, so no real changes are perceived on other platforms.

BFU USERS
This putback is a minor FLAG DAY for the developers who still
use bfu(1M) script to update their systems. This project updated the
bfu(1M) script to add a new entry to /etc/mach file. Developers
should either use the latest version of the script from
/ws/onnv-tools/onbld/bin/bfu
or use the bfu script built in the tools directory of their ON workspace
after updating the workspace from the latest Nevada ON gate. Not using the
latest script will not enable the new interrupt framework even if the
platform supports it.
Bugs on this should be filed against:
solaris/kernel/mp-platform-x86
solaris/utility/pcitool
solaris/utility/mdb
solaris/kernel/ddi
For any questions or issues on this, please send an e-mail to
apic-...@sun.com.
